Search - "not a database"
-
I hired a woman for senior quality assurance two weeks ago. Impressive resume, great interview, but I was met with some pseudo-sexist puzzled looks in the dev team.
Meeting today. Boss: "Why is the database cluster not working properly?"
Team devs: "We've tried diagnosing the problem, but we can't really find it. It keeps being under high load."
New QA: "It might have something to do with the way you developers write queries".
She pulls up a bunch of code examples with dozens of joins and orderings on unindexed columns, explains that you shouldn't call queries from within looping constructs, that it's smart to limit the data with constraints and aggregations, hints at where to actually place indexes, how not to drag the whole DB to the frontend and process it in VueJS, etc...
New QA: "I've already put the tasks for refactoring the queries in Asana"
I'm grinning, because finally... finally I'm not alone in my crusade anymore.
Boss: "Yeah but that's just that code quality nonsense Bittersweet always keeps nagging about. Why is the database not working? Can't we just add more thingies to the cluster? That would be easier than rewriting the code, right?"
Dev team: "Yes... yes. We could try a few more of these aws rds db.m4.10xlarge thingies. That will solve it."
QA looks pissed off, stands up: "No. These queries... they touch the database in so many places, and so violently, that it has to go to therapy. That's why it's down. It just can't take the abuse anymore. You could add more little brothers and sisters to the equation, but damn that would be cruel right? Not to mention that therapy isn't exactly cheap!"
Dev team looks annoyed at me. My boss looks even more annoyed at me. "You hired this one?"
I keep grinning, and I nod.
"I might have offered her a permanent contract"45 -
Yesterday, in a meeting with project stakeholders and a dev was demoing his software when an un-handled exception occurred, causing the app to crash.
Dev: “Oh..that’s weird. Doesn’t do that on my machine. Better look at the log”
- Dev looks at the log and sees the exception was a divide by zero error.
Dev: “Ohhh…yea…the average price calculation, it’s a bug in the database.”
<I burst out laughing>
Me: “That’s funny.”
<Dev manager was not laughing>
DevMgr: “What’s funny about bugs in the database?”
Me: “Divide by zero exceptions are not an indication of a data error, it’s a bug in the code.”
Dev: “Uhh…how so? The price factor is zero, which comes from a table, so that’s a bug in the database”
Me: “Jim, will you have sales with a price factor of zero?”
StakeholderJim: “Yea, for add-on items that we’re not putting on sale. Hats, gloves, things like that.”
Dev: “Steve, did anyone tell you the factor could be zero?”
DBA-Steve: “Uh...no…just that the value couldn’t be null. You guys can put whatever you want.”
DevMgr: “So, how will you fix this bug?”
DBA-Steve: “Bug? …oh…um…I guess I could default the value to 1.”
Dev: “What if the user types in a zero? Can you switch it to a 1?”
Me: “Or you check the factor value before you try to divide. That will fix the exception and Steve won’t have to do anything.”
<awkward couple of seconds of silence>
DevMgr: “Lets wrap this up. Steve, go ahead and make the necessary database changes to make sure the factor is never zero.”
StakeholderJim: “That doesn’t sound right. Add-on items should never have a factor. A value of 1 could screw up the average.”
Dev: “Don’t worry, we’ll know the difference.”
<everyone seems happy and leaves the meeting>
I completely lost any sort of brain power to say anything after Dev said that. All the little voices kept saying were ‘WTF? WTF just happened? No really…W T F just happened!?’ over and over. I still have no idea on how to articulate to anyone with any sort of sense about what happened. Thanks DevRant for letting me rant.15 -
Guy called in:
Guy: hello, i can't seem to login to the sql database, could you check if the ip whitelist went right? It's on the *names server* server.
Me: *checks if guy is calling from an authorized number* - nope.
Me: I'm sorry but you're not calling from an authorized number so I can't check that for you!
Guy: no you don't understand. I don't want any of this not-authorized bullshit, I just want a solution for this right now.
Me: and I just want you to call from an authorized number.
Yeah, I actually said that. He wasn't very happy 😅
I'm still employed by the way 🤣12 -
Ooooooh I just skip a heart attack and shit myself at the same time, thank god for error "can not delete database, database is in use"8

I just had a client complaining on the phone that she read my database design documents and that they are all wrong and need to be done again. Because things like varchar and int are confusing. And nobody understands what they mean. She asked around and nobody understood it.
Ooh, and I should place the customer name in more then one table because it would be handy to have in several places.
Spend a hour on the phone trying to explain that these documents are not intended for her. They are not for her to understand.
I make these documents to build a stable product and in case something bad happens to me its easier to pick up for another developer.
Long story short.. I'm currently making a document that explains the database design... Getting paid for it..... But fucking hell. Somebody save me.10 -
Our company got attacked last month by what i believe was a code time bomb from a ex employee. And it was brutal, website hacked, email server not responding, locked out from database servers. The IT department asked for my help and I was more than happy to do it. Long story short I got every thing back working smoothly. The IT guys ask for a favor to not include this in my monthly progress report. Fine by me. But then they went out and tokd the top management that they are teaching me about the networks and servers so thats why I was working with them last month. Fucking assholes. Not going to help them any more.3

So, as everyone knows on here by now (or, a lot of ranters), I am a fervid privacy person.
Appearantly a new surveillance law in my country is about to extend mass surveillance/hacking a lot. So here a rundown of what they are about to be allowed to do (stuff that is not okay imo and this is the reason I am so pro-privacy):
- Mass Data Gathering: The intelligence agency over here (lets call it IA from now) can pretty much record everything send through the country.
- Extra Protection: If they want to conduct surveillance on journalists/lawyers, they have to go through extra channels first at least.
- Data/survaillance sharing: The IA is allowed to share their raw/filtered data with foreign intelligence agencies without limits. Also, they're allowed to conduct surveillance based on foreign requests.
- Secret DNA database: A secret DNA database will be created which can store the DNA profiles of any person who has commited any kind of crime. These profiles are allowed to be stored for a maximum of 30 years. This database is allowed to be shared with any foreign intelligence agency.
- Hacking: Unlimited power to hack any device deemed neccesary to hack in relation to crime. From computers to smartphones and so on. Also, it's allowed to use zero-days without reporting them to the vendor (we have seen what can go wrong with that through the ShadowBrokers scandal).
- Automatic Database Collection: They are allowed to directly tap into any database they see required (banks, healthcare, messaging services and so on). Practically this can lead to backdoors being build in because if you don't cooperate, you can go to prison. (mother of god I am not using anything closed source anymore if possible).
So yeah, this is pretty much the reason why I am so privacy consious. This country is fucked.57 -
A US senator or judge or whatever his title is said today that he wants companies/governments to build a 'responsible encryption' system.
Preferably that would exist out of a big ass database which stores the private keys of citizens so in case a person loses their private key or the government needs access to encrypted content, that is possible.
NOO, WHAT COULD FUCKING POSSIBLY GO WRONG!?!?!
Seriously those kind of people should not be allowed to have the kind of positions they have.
This shit makes me so angry.45 -
"Do you have 2 factor auth for the database?"
a customer asked. I stared on the wall in front of me and suddenly fel and urge to punch and piss on something.
I took a deep breath while thinking to myself
*Oh boy, here we go. Another retard*
I put on my nice voice and asked:
"What you mean?"
The customer seems confused, as if my question did not make sense and he said:
"TWO FACTOR AUTHENTICATION! Dont you know what it is? To make the database more secure."
I was fucking right, this person reads to much shit. The fact that the email signature of that person said "Wordpress Developer" made me more angry.
I, still with the nice voice asked
"How would that work?"
"Two factor authentication when I am connecting to the database."
"So, do you want it by SMS then? You'll get alot of messages if it is going to send you one every time a query is made."
The following 7 seconds was dead silent until I heard the person hang up.3 -
I found a healthCheck function while troubleshooting an old application for a large auto manufacturer today. The healthCheck function was running several times a day on a timer. The function tries to insert a record into the database and returns whether or not it was successful. It was written in 1999 and has to date inserted over 2.5 million records into the database! 1/3rd of the data for this application was the same record.
How the hell did nobody notice this for 20 years!!!3 -
Me 5 years ago : "Guys we are gonna have a perf..."
CEO : "Not now, we need to deliver that functionality asap"
Me 3 years ago : "Guys, performances/scalibiluity will hit us like a trucK'
CEO : "Not nowem a new functionality needs to be done ASAP"
Me 1 year ago : "We are gonna be hit by a tank. We won't even understand what happens"
CEO : "I'm sure we can manage"
2 Days ago : Plateform quasiment down, response time in MIONUTES instead of milliseconds, database on fire.
CEO : "WHAT THE FUCK !!! GO FIXC I ASAP WE CANNOT HAVE THAT SHIT HAPPEN".
This is a brief summaru of working in a startup.9 -
Project Manager: You used a hash/salt to encrypt the password in our customer database?
Me: Yes.
Project Manager: That's mean we will not be able to see the password?
Me: That's the whole point. Why would you want to see what password customer is choosing?
Project Manager: Change it. Use random encryption method.9 -
So a coworker wrote this -- a function that returns a view if a specific object exists in the database. Now what would happen said object doesn't exist in the database? Forget about returning false and handling it properly, he decides that the function should print (echo) a zero! Not to mention almost all his if-else blocks prints a fucking zero when the if condition is false (there are 8 of them, if you're asking). Error messages? The hell with those.
He is now the PM btw. I've had enough of this shithole.14 -
Ex-coworker of mine fixed this bug a week after the site was launched and has gathered several thousand users in database.
Yep its exactly what you think it is, each time one user would update its infos, it would update his infos to all the users in the database.
Luckily I was not in charge of the project in that time, so it was really fun to watch how everyone's name was changing every couple of minutes for a whole week :D12 -
I... uhm... I... I can't... I ... I can't even.... THIS IS LIVE IN THE CLIENT'S SITE WHERE ANYONE CAN CREATE A LOGIN WITH NO VERIFICATION WHATSOEVER AND SEE THIS WHICH IS LINKED TO A BIG RED BUTTON THAT RESETS THE WHOLE DATABASE, YOU FUCKING DUMB PIECE OF SHIT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
// This event clears the entire solution in all active clients, truncates the database and also removes any stored PDFs in the server folder
$(document).on('click', '#resetDB', function () {
// This event only happens if the user correctly enters the password, this is to prevent other users than the admin from performing this action
var answer = prompt("Please enter the password required to perform this action.");
if(answer == "-REDACTEDBECAUSEHOLYSHIT-") {
socket.emit('resetDB');
} else {
alert("The password is incorrect, please try again!");
}
});
AAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!111!!1!!11!1!!1!1one!one!!!11
(I'm not inventing this, even though the "site" is internal only and not accessible through the web. That does *not* make it any less stupid!)11 -
You know your week starts great, when you receive a call, that the whole shop database of a company is not working anymore.
Turns out MS Fucking SQL decided to drop all tables, just because the harddisk was full.
A SERIOUS FUCK YOU TO MICROSCHROTT!
It's not a lot of fun, when 15 people have to wait for you about 1 hour, until it is restored.
Why does this have to happen on a monday?10 -
Went with a cousin to hospital for vaccination .I took a pen and wrote: "Anti-Virus database updated 09.01.2017" . Now I am not allowed to stay with my cousin :(

Data scientist: we need to whitelist a pod to connect to a database
Me: Whitelist? We don't use whitelists on private databases
DS: It's the new data warehouse database
Me: is it on <X> VPC?
DS: I'm not sure what that means but its ip is <real world ipv4>
Me: Are you hosting a publicly accessible database with all our end users information?!
DS: ...
Me: There goes our SOC2 audit controls...
DS: how long until you can white list it?
Me: I won't be whitelisting it. You need to put it on a private VPC and peer with the cluster, you'll have to rebuild all the Terraform and redeploy
DS: We didn't use Terraform because it takes too long, just white list the pods IP.
Me: No. I'm contacting the CISO and CTO...21 -
A fun experience with a client:
Client: We want to use a database in the cloud without internet.
Us: Uhm that's not possible.
Client: Why not? You don't need internet to use a cloud database, because it's in the sky right?
.....
We will never forget our first client.
p.s. he also wanted to use his wifi printer without internet and cable
I pray for a future where clients have a better understanding of IT related concepts🙏2 -
manager (not technical) : we need to add blocking feature to our social media.
me : adding block feature will take 2 weeks developing.
manager (not technical) : why it takes too much time to develop you can just delete the user from the database if a user blocked him.
me : hahahaha ... just ... delete ...
manager (not technical): ...
me : hahahhahahhaha.....

No amount of backend code is seen as progress by client.
Have a web store app project that is running and looking beautifully and is currently connected to nothing.
Got scolded this week for not having any new deliverables.
Spent 15 hours on security updates and database architecture.5 -
Not exactly a security bug, but there was a company that made a Django app for some internal work and later open sourced it. I was browsing through the code and I saw that the config file had an IP address and a hashed password for the database credentials
When I tried to use them, I was able to login directly to their read replica RDBMS, I had access to all their customer data (including phones & home addresses)
Being the saint I am, I informed them of the ignorance made by their developer and was presented with some cool swag.5 -
I HATE working with MS Office products. Yes, Access, I'm looking at you, you backwards, whanabe database reject! You're invalid as a serious SQL database and retarded as an data application suite.
VBA, make up your MIND with your damn function calls! Either require me to use parenthesis or don't! I'm sick of this conditional parenthesis sh*t!
While we're talking about not making up your mind... screw 'sub', you half wit language! Either use functions like a real language or go the f&$k home and make room for a language that knows what it's doing!
Oh!!! WHY... WHY! do you have null AND... NOTHING?! Who... Who... WHO invented "nothing"?! And what sick joke are you playing at with isnull() and empty()??? How many damn ways so you need to test for "no value"?!?!
Access... That's right, I'm not done with you yet... How is it you've survived this damn long in the business world with all of the databases you corrupt? Sure, you suck as a real database, but at least have some freaking pride that people even USE you! How DARE your corrupt yourself with the regularity you seem to have! I wish my bowel movements were as regular as your database corruptions, for the love of humanity.
F$@k you, VBA! F@&k you, Access! F$#k you, MS Office! And Fuuuuuu$k YOU Microsoft for shoving these half assed reject tools down my throat!
I hope your cloud uses Access as a back end and gets some injection virus.
*Takes deep breath* need to say that.10 -
We've built a web app and now a client wants a VPN acces to the database of web app. When asked why, they said they want to occasionally pull some data out. 😱
We said no, and this is what they wrote:
"We’ve got live VPN access to every other web database we work with – why is this different?"
Well because maybe we know that we can build you an export of whatever you want, prepare you API calls for getting data to your CRM, but hell I'm not giving you access to the production DB.5 -
Let's settle this:
Blockchain is just a dumb database, the feature that makes it amazing is trust-less ness.

I'm currently 40h/week meeting attender. I'm not enjoying my life right now.
Today I have a meeting about the legal requirements of an invoicing system, in my role as database administrator — the meeting will mostly be lawyers bickering over what the addresses of subsidiaries look like on invoices and which taxes should apply to services provided across borders.
Wait, I can play Factorio during this meeting and say "yeah that sounds OK" once in a while. Not the worst job after all...10 -
I once asked my database teacher whether he is certified on any database system or not and he said if I was then why would I be a teacher !!!3

The reason why I changed my username ( I'll just be honest here )
I was working on a website. I noticed that entries were submitting yesterday but today new entries were not showing up on database. It was like my database refused to insert new rows but there was no new error in log. I kept trying for almost half an hour, read all the answers on stackoverflow, read docs, tried different methods. Nothing worked. I was fucked up. Completely fucked up.
In frustration, I just stared my database for 10 mins without a single blink, and then I noticed this thing 'showing 25 out of 78 rows'
(-_-)
I clicked on 'show all'
AAAAAAND
I felt retarded.
Okay I can give an excuse that last time I saw a database was a year ago, but still.. how retarded you need to be to not see this FUCKIN 'SHOW ALL' when it is on the TOP of the FUCKIN TABLE!!6 -
A recent project actually taught me how HORRIBLY STUPID it is to store large bodies of text in a SQL Server database. There were millions of records with pages of compressed text each.
More and more text records pile on every single day. Needless to say it was becoming super slow and backups were taking WAY too long.
After refactoring them out as compressed files to disk storage (I love you, micro-services) and dropping them completely from the database, the backup size went from 90gb to 3gb!
It's not every day you get to see a dramatic result like that from a refactor.
Lesson learned, and yes it was quite cool.6 -
For fucks sake, corporate IT has locked a database application for new entries because it will be phased out by the end of the year. However, the new application is not yet working.
The interim solution? An excel sheet on a shared network drive. In fucking 2020! Unbe-fucking-lievable!12 -
So my marketing dept request us to perform a SQL injection to someone's bank account. I refuse to do it.
1. Most bank no longer use Relational Database , they use something like NoSQL Database.
2. Even if the bank Use Relational Database system, I assume their security must be high, validating my session maybe...
3. I am not going to do shit like this for illegal purposes, well this task sounds super illegal to me
4. Hacking is not a part of my job description. I was hired to be a Senior Fullstack Mobile App Developer.
This is screwed up !24 -
Sometimes I think back to all the funny shit that happened and how simple stuff fucks everyone
- tired Database engineer deleting (not dropping, literally rm -rf) the database files on the wrong server
- Microsoft delivering viruses through updates
- Pissed and stubborn dev deleting his one line library repo which does something like removing a char left side of string fucking an unmeasurable amount of other projects
- Adobe getting hacked and exposed for storing passwords in plain texts
- a doubled line causing a bug called heartbleed in a fuckton of webservers
- a Tutorial Company getting kicked from github because their repo got so big github staff had to maintain the repo manually
- and an old one: bad code crashed a space shuttle16 -
"please use a secure password*"
* But don't make it too secure, 20 Charakters is enough.
Why would you fucking do this? The only reason I can think about is a scenario like this:
"How do we store the passwords in the database?"
"Just like anything else?"
"So I create a VARCHAR(20)?"
"Yeah why not? It's good enough for a name, and you shouldn't use your or anyone else's name as a password, so it should be perfect"10 -
Email subject: Urgent need for developers!
Email body: We found you in our database, and think you're a match for this position! Requires 5+ years of C++ experience
Apparently C# == C++. Good luck finding an appropriate candidate, buddy. I was tempted to send them an email pointing out their error, but I'm not too good with "pointers"4 -
was a member on a web developers group on Facebook.
someone posted a question:
- I am getting error 500, how can I fix it (yes just like that, no error message, not even what technology he's using)
comment 1 : how can I build a website please? (I mean, wtf, you can at least post a separate post)
comment 2: check your database, MySQL has problems bla bla ( yes, don't know how he guessed that ia the database is the problem, and who tell you he used MySQL anyway??)
Me: what the hell am I doing here?
*Quit the group*8 -
Web Development on a single laptop is tough....
Window 1: editor, tabs for markup, styles, server, terminal
Window 2: browser...so small that everything is in low res mode, if not mobile.
Window 3: database, stress testing system and making sure data flows properly.
Window 4: design specs.
*shudders*5 -
The experience that made me feel like a dev badass was when a teammate accidentally deleted the database for production and I had the latest backup. Everybody was panicking not until I told them I had the solution4

Recently had a meeting with the company that acquired my startup, where I was required to relinquish root/admin access across AWS, SSH, and database. It was decided that I held too much power, and will now only have read-only access to develop. I'm not entirely sure what I do for work now.5

Yesterday a colleague of mine told me that another colleague has done this in his web application for a subject:
For checking user and password, he did not query a database, but instead he checked information in a HIDDEN DIV in the html page.
Reason: "this way I don't lose my precious time".
I think of that and I'd like to punch him. People like him are the reason websites in Italy suck and my University web infrastructure sucks (he worked as intern on that).
My. God.7 -
Early in my database developer career, I started a new job at a mortgage company. I was poking around the code, just getting familiar with things.
One script identified properties in certain states/territories for special handling:
AND STATECD IN (‘PR’, ‘HI’, ‘AL’)
I thought “Puerto Rico, Hawaii, and ALABAMA?? One of these things is not like the other…”
Yeah, that was supposed to be Alaska (AK)… But they’ve been special-handling properties in Alabama for years. -
Boss wants to scale our webservers because it seems they're having performance/capacity issues....
I'VE BEEN TELLING HIM FOR WEEKS IT'S NOT THE SERVERS!!! IT'S THE FACT THAT EVERY SINGLE QUERY HITS A SINGLE MONGODB... AND NO CACHE EITHER... AND THE DB CANT BE ENTIRELY LOADED INTO MEMORY AS ITS TOO BIG FOR RAM ON A SINGLE SERVER...
HOW THE FUCK CAN YOU SCALE IF EVERYTHING HAS A DEPENDENCY ON 1 NON-DISTRIBUTED DATABASE?6 -
At a previous company, a new IT director decided we should outsource the development of a webapi to another company, but this outside company would not be allowed access to the database, so we had to develop a webapi to provide data to the outside company's system, so we could call their webapi and get the same data back.6

For my school project that was due awhile back my group ran into the problem of a certain feature not working on a site we made. I had a test version of the site and it was working perfectly. Both the test version and the project site had the exact same code. We couldn't figure out why it wasn't working and so we just turned it in and took the point hit.
Today I was thinking about it because I was still annoyed/upset that the site feature didn't work. I started talking it through with a friend and in the middle of it stopped-I figured out why it didn't work. My teammate didn't actually update the database, he just downloaded the code to the database and was using an outdated version of it. I suddenly stood up and screamed, "F***!" At the top of my lungs.
I startled my friend so bad that she spilt beer all over herself.1 -
Jim comes in and tells me that server RENEGADE-DB1 has no more space left and that he tried to remove a few ridiculous sized log files, but that the system wouldn't allow him. So he used some 3rd party tool to shutdown the processes that used those log files and then succesfully removed them.
Now the database is not working and Jim needs my help.
Hello darkness my old friend.11 -
Database tip of the day:
Spent hours on Amazon's DynamoDB and ultimately found it couldn't do what I wanted, not without a complicated workaround.
Switched to Mongo and had it working in literally under 5 minutes.
Hooray for Mongo 😀3 -
Dev: Hay dude , look this page is broken, how long has it been like this.
Me: No? 🤔, Weren't you working on the Database for this yesterday?
Dev: I didn't change anything yet...
Me: Okay, let's do a git bisect and see where this came from.
...After going back in history and checking out like 3 commits.
Dev: It's fine I'll just search for it
Me: 😕, that's what we are doing the bisect for?
Dev: But we've already looked at so many!?
...After some time of convincing, finds good commit, does the bisect and finds offending piece of code. The database details changed.
Me: okay so while it's still pointing to the old database it's working but switch it to the latest one and it breaks. You sure you didn't change anything?
Dev: I didn't do anything.
Me: okay well it seems to me like it must be a database issue, let me know what you find.
10min later...
Dev: Hay dude, soo I found it, I accidentally renamed a table
In my mind: 😲😲😲
I hate working at a company with bad practices like saving database config into git and not making a copy of the database when you intend to work on it, and not edit the f'ing live instance! Not even close to the luxury of migrations.1 -
That feeling when you try to get entries from a mongodb and it doesn't put out anything, not even errors and after 4 FUCKING HOURS trying, googling and looking around on stackoverflow, you realize THAT THE PROGRAMM DIDN'T EVEN CONNECT TO THE DATABASE
That's the stupidest problem I ever had IN MY ENTIRE FUCKING LIFE
Thanks devRant, I feel better now.4 -
my boss asked me to log in 1h30 after i logged off because "a user has been experiencing this bug the entire day and i should fix it because we're on maintenance tomorrow " but a) it's a known bug that we can't reproduce, he should've notified sooner the issue; b) it's not a big deal, i can fix it tomorrow, it's just not ticking a column in the database; c) I'm off work, go cry about it2

I was having dinner with two girls, one a project manager and the other some finance reviewer or something like that. We were discussing our line of work and I was talking about how bad quality code affects everybody and the finance reviewer girl goes like (and I quote) "In our company we use polymorphism, inheritance and encapsulation so it's not a big problem. So our database has a parent class and we only use the parent class". I was at a loss for words. I mean, if only more programmers just did that, right?14

Just got a lection from my manager.
Today he sent me an email with request to change validation on one field validation from decimal(5,3) to int which will be 5 digit number. Ok i did that, I changed it on UI, changed validation, changed mappings, changed dtos, created migration files, and changed it in databse. After i did all of that I replied to his email and said that ive changed validation and adjusted it in database.
After my email here comes rage mail from manager with every fuckin important person in cc I kid you not. Manager is asking why the fuck did I change database when Ive could only use different validaton for that field on UI.
I Almost flipped fuckin table. What does validation good do if you wouldnt be able ti save that form? And form has like 150 fields. And if I left validation only everthing would fuckin break.
Sometimes i think that its better not to think.

The company I work for is requiring customers to submit credit card info in an online form which then gets stored into our "secure database". Which employees then pull and charge the card later on. They're also telling customers that the form is "encrypted". This is all because they're too fucking lazy and not patient enough to wait for someone to integrate a payment gateway. This is a lawsuit waiting to happen.5

So last night i was dealing with some mysql query issues trying to grab some complex data from a relational database and ended up giving up.
This afternoon i was about half-asleep going to nap, not even thinking about the code and randomly came up with the solution.
A few hours later i made the changes and it works as intended.
Anyone else solve code subconsciously ? 😂😂😁😁12 -
One thing I've noticed about devRant is the ratio of web dev/mobile dev posts to database/architecture/big data dev posts. There's A LOT of you web peeps out there, and not enough data dudes, which I guess justifies my constant demand, salary and lack of competition. Just an observation.9
-
40 minutes to realize that the "Access denied" error was not about the database on the server but about a local file.
And a sudo solved everything2 -
I hired a coder to write a WordPress plugin on my dev server. He no longer works for me and is unreachable. The plugin does most of what it needs to do. But when I dig into the code and the database to find what should be obvious bits of code that do obvious things? None of that code is found. Not even with a recursive directory keyword search for that should be easy to find like CSS class names and IDs. Even the data that comes from the database and that I see on the screen is not actually present in the database!!! Yet it all works. I'm pretty sure at this point the code and data reside in a parallel dimension only the coder can get to. How do I debug code that doesn't actually exist?!13

SOO.
I work at a grocery store, right. Cashier and all ya know, livin the dream. And whoever manages our product database. Needs to get thekr stuff together. We managed to confirm the DB isn't the same across the the registers. So now I have a bunch of stupid pictures of barcodes in my phone so I can make error reports for each and every single item that doesn't ring up. I know not ready dev related. But a dev somewhere is slacking5 -

I once wrote a room planning application on unity, to allow people in my company to book meetings using tablets attached to the room doors.
Turns out the c# Datetime object unity uses was highly localized and therefore had a different formats on each different device.
I saved those timestamps into a SQL database and eventually all devices crashed due to having some Datetime format they could not parse.
Had to fully bypass the datetime and reinvent it essentially and had to reset the database.
I think it's needless to say I'm not particularly good in dating.4 -
Once Upon a Time.........
Three database SQL walked into a NoSQL bar.
A little while later they walked out Because they could not find a table.1 -
<just got out of this meeting>
Mgr: “Can we log the messages coming from the services?”
Me: “Absolutely, but it could be a lot of network traffic and create a lot of noise. I’m not sure if our current logging infrastructure is the right fit for this.”
Senior Dev: “We could use Log4Net. That will take care of the logging.”
Mgr: “Log4Net?…Yea…I’ve heard of it…Great, make it happen.”
Me: “Um…Log4Net is just the client library, I’m talking about the back-end, where the data is logged. For this issue, we want to make sure the data we’re logging is as concise as possible. We don’t want to cause a bottleneck inside the service logging informational messages.”
Mgr: “Oh, no, absolutely not, but I don’t know the right answer, which is why I’ll let you two figure it out.”
Senior Dev: “Log4Net will take care of any threading issues we have with logging. It’ll work.”
Me: “Um..I’m sure…but we need to figure out what we need to log before we decide how we’re logging it.”
Senior Dev: “Yea, but if we log to SQL database, it will scale just fine.”
Mgr: “A SQL database? For logging? That seems excessive.”
Senior Dev: “No, not really. Log4Net takes care of all the details.”
Me: “That’s not going to happen. We’re not going to set up an entire sql database infrastructure to log data.”
Senior Dev: “Yea…probably right. We could use ElasticSearch or even Redis. Those are lightweight.”
Mgr: “Oh..yea…I’ve heard good things about Redis.”
Senior Dev: “Yea, and it runs on Linux and Linux is free.”
Mgr: “I like free, but I’m late for another meeting…you guys figure it out and let me know.”
<mgr leaves>
Me: “So..Linux…um…know anything about administrating Redis on Linux?”
Senior Dev: ”Oh no…not a clue.”
It was all I could do from doing physical harm to another human being.

My manager is instructing my team to add a feature that can only be enabled for users by running an update script in the database.
When I argued that it's not really "complete" if it can't be turned on without someone going into the production database, I was told that not only is it complete, but they plan to have our non-technical customer service enable it for customers if the customer requests it...
Apparently giving everyone and their brother write access to prod is a good idea, but implementing a checkbox is a "waste of time and would cost too much money".
Probably going to float my resume... :-p2 -
This is fucking bad. I just stumbled across a database online, unencrypted plain text containing ALL details of thousands of students at my university. Full names, ID number (SSN), student numbers, address, family info, medical aid info, physical fitness reports
What do I do? I was not on any VPN or proxy when I accessed it19 -
Clients don't know what they want!
Was handed a detailed report and asked if I could create a webpage to dynamically generate the same thing from our database. Sure its ez ps lemon squeezy.
Simple page and database query. Boom, done. Exactly matched what they gave me.
They ask why some of the data isn't there. Uh well you cunts it wasn't on the original report...so it's not there obviously.1 -
A few years ago I found a public AWS S3 bucket owned by a fortune 500 company containing a database dump backup with all of their users unsalted md5 hashed passwords.
I didn't report it because I don't want to get sued or charged. I don't know whether it's still public or not.6 -
He wanted to hire me as CTO but insisted of defining architecture himself even though he admitted he has no tech background. He insisted that his CRM doesn’t even need backend because “we have database”. He was dysgraphc but completely ignored accessibility, including measures for dyslexic people. He called his product “startup” but denied that startups need to constantly validate ideas and denied the conception of a/b testing, offering no alternative.
He also wanted me to work for free.

Hello DevRant! Time for my first rant. As the saying goes: Everyone should put his own house in order first. So why not rant about myself before i rant about others...
Dear past self next time be less an idiot and enter a database into the persistence.xml wich actually exisist so i don't waste a fucking hour or something like that, for looking what's wrong with my JDBC driver....

The ups and downs of a corporate database developer job:

We just got into a malicious bots database with root access.
So guard duty gave us some warnings for our tableau server, after investigating we found an ip that was spamming us trying all sorts. After trying some stuff we managed to access their MySQL database, root root logged us in. Anyway the database we just broke into seems to have schemas for not only the bot but also a few Chinese gambling websites. There are lots of payment details on here.
Big question, who do we report this to, and what's the best way to do so anonymously? I'm assuming the malicious bot has just hyjacked the server for these gambling sites so we won't touch those but dropping the schema the bot is using is also viable. However it has a list of other ips, trying those we found more compromised servers which we could also log in to with root root.
This is kinda ongoing, writing this as my coworker is digging through this more.11 -
Completely got my localhost and live database confused and dropped the whole live server. And there was a power outage so the last backup is from Friday. Luckily not completely live, but still having a stream of people walking in. Also pretty obvious that they are talking about me especially since there's no other shes in the department.5

Website from 2011.
Made from a 2007 template.
The database was in latin1.
The template wasn't even a good one, an adapted hotel booking example for a main page, contact, and news.
There were unused variables and weird functions everywhere.
3 years later and I still don't understand how it managed images. Not that I care to look back. -
And 1&1 again... I tried to create a new database... 1&1: “the password is to long. Please choose a password that is not longer than 16 characters.” 🙃9

During the first few months of my first professional development role, I had a really odd bug on a live WordPress site that I couldn't replicate locally, despite having the same code and dependency setup. Using WordPress was a mistake but not the one I'm writing about.
I decided to copy live site and its database. Then I thought it best to delete all the users from the copy of the database (I'm not sure why I thought I should do that) and I did so via the WordPress admin UI.
What I wasn't aware of was there was a custom function to email the user before they get deleted.
I got inundated with hundreds of confused/angry/hysterical users about their accounts being deleted, even though they hadn't actually been, and a telling off from the boss.1 -
I'm debugging someone else's 10 year old legacy .asp web application (shoot me now), and I'm trying to find the most recent records in a database table.
Why is the most recent record from September of last year?
Oh.
Because they're storing the datetime value as varchar (40).
Good thing they were smart enough not to waste disk space by using varchar (255)!4 -
Let's say you have a MySQL database table for jobs. Each job has 1 associated ticket. You want to keep track if the ticket is closed or not. Every sane person creates jobs table, tickets table, keeps bool value for ticket state and relationship between them.
But because our database is designed by a half braindead amoeba, we have one table only, so each job has to be updated individually with a new ticket number and its state. Beacuse it sooo much faster to update (daily!) 13k jobs than just 100 tickets.
As a bonus - if the ticked is closed, the column "ticket_closed" is "No", if it's still open the value is "FALSE". Yes, both as varchar/strings.7 -
Just because I manually updated a database record, does not mean I can fix your bluetooth headset. Now fuck off.1

So, part of my job is working with SQL. Not my favorite technology to work with. But the tables have mostly non-descript fields, multiple schemas in the same table, and encoded relationships spanning multiple tables. Yes, the database from hell! On top of that, there is very little documentation on this mess. -- And my boss wants me to write queries against a combination of these tables to make sure the program is working. RIGHT...3
-
Junior coders want to argue about database design saying an employee table in the database does not need a start date and end date because the requirements don't say that. I am doing gold plating he says. He didn't care that I had been doing this over 10 years and he 0 years. Oh yea and by the way I have never been given specific requirements about database design.4

I accidentally started a reindex on a collection that had 14 million records in the middle of the day. Caused an outage in a major portion of our applications for about 3 hours. Worst thing was that once I pressed enter, I realized that it was for the production database, and not the staging database like I intended. I immediately went to go tell the dev ops lead, and he basically said, "whelp, let's just sit back and watch the world burn. Not much we can do about it"1

What's this erogant world?
Someone asked a question in Stack Exchange, he put his design of a school management database and asked for suggestions.
Well, there are many things to improve, relations and data types etc..
BUT, he got 10 very long answers about why every student has exactly a father and a mother, why not 2 mothers and 3 fathers and all some off topic talks that could be said in 1 line..
Like what the... ok we know you're gay but answer the question without being an attention greedy12 -

What a silly end of the week. Have to continue developing at a project a student started at our company. Today I had a phone conference with the client. They told me there where missing several data. At first I thought it is only a frontend issue but now I know it is a database issue so I have to work through several database procedures which are all undocumented and the student who build those is not reachable. Business integration ftw

Still dealing with the web department and their finger pointing after several thousand errors logged.
SeniorWebDev: “Looks like there were 250 database timeout errors at 11:02AM. DBAs might want to take a look.”
I look at the actual exceptions being logged (bulk of the over 1,600 logged errors)..
“Object reference not set to an instance of an object.”
Then I looked the email timestamp…11:00AM. We received the email notification *before* the database timeout errors occurred.
I gather some facts…when the exceptions started, when they ended, and used the stack trace to find the code not checking for null (maybe 10 minutes of junior dev detective work). Send the data to the ‘powers that be’ and carried on with my daily tasks.
I attached what I found (not the actual code, it was changed to protect the innocent)
Couple of hours later another WebDev replied…
WebDev: “These errors look like a database connectivity issue between the web site and the saleitem data service. Appears the logging framework doesn’t allow us to log any information about the database connection.”
FRACK!!...that Fracking lying piece of frack! Our team is responsible for the logging framework. I was typing up my response (having to calm down) then about a minute later the head DBA replies …
DBA: “Do you have any evidence of this? Our logs show no connectivity issues. The logging framework does have the ability to log an extensive amount of data regarding the database transaction. Database name, server, login, command text, and parameter values. Everything we need to troubleshoot. This is the link to the documentation …. If you implement the one line of code to gather the data, it will go a long way in helping us debug performance and connectivity issue. Thank you.”
DBA sends me a skype message “You’re welcome :)”
Ahh..nice to see someone else fed up with their lying bull...stuff. -

I just wrote a function that creates a configuration struct that is stored in a Singleton struct, but to create it I called the Singleton to get a connection to the database.
This created an infinite recursive function that maximized connections on the database, as the Singleton never got fully initialized. Not a good idea.
So to fix this I created the configuration after the creation of the Singleton, still calling the singleton from within the function. This worked.
Then I remembered that I could have just passed the connection as a parameter to the function. Like I've done a million times before...
It's time for the weekend, I need a break -

Wrote a small code to test my "Reset Password" feature, service console kept printing: User not found and returns 404

Made a backup script today that backs up our site files and database (total size 34gb, we have 70gb storage)
the script takes 1:10 hours to far the website files and backups up the database and somehow when running in a detached terminal because my boss wanted me to run it at 4:20pm when I'm leave at 5:05pm( what could go wrong) it went in a infinite loop and filed our storage.
Our provider just called our boss that his drive is full ( why can you even see that)
Well it will not be a fun morning tomorrow6 -
I just saw this job opening for visual artists (not me at all, but still curious what kind of person they are looking for).
https://artstation.com/jobs/J1OY/
It's so detailed, a person applying would immediately know what is expected of them and what their role will be. Why isnt this like this for most programming jobs?
Example of programming job opening descriptions:
Knowledge of a backend language (ex: python, java, C++)
Experience with databases
Experience with making and using APIs
This does not in any way describe what I will do at all. (yes this is a copy of most useful information of a job offer I recently got). It does not state which language to work with (I know none of the listed ones, but I do know PHP, C# and javascript/typescript (yes I know) for backend languages.
What kind of database experience? I have worked as supermarket employee and when I had to order new things I had to use a application to update the database. (Ive done more, but who does not have experience with any kind of database in any way)
TL;DR The artist job opening description is so well described. Why isnt it that way for programmers more often -
This is a public service announcement with a threat at the end of it:
"Do not, I repeat, do NOT attempt to write web applications, or any particular sort of application that works with a relational database (damn near more than half of applications) without a PROPER grasp and knowledge of SQL.
I do not want to see you reaching out for an ORM either, no, you need to learn to properly design a database or to properly interact with them AT most before you even attempt using an ORM OR designing an application from the beginning, shit will only hurt you in the long term I promise, learning SQL can go a looooong fucking way and most DBA's I know make way tf more than people think they make, it might even be an interesting career choice"
If you do not follow the above advise, and I see your ass reaching for building a web application without the above knowledge I will be under your bed at night, putting oil in my hairy body before I jump into bed to you and leave you confused for the rest of your life.
Build to learn, YES, but for the love of Chamberlain and Boyce PLEASE do not neglect SQL. I have seen such neglect REACH production and I am currently wishing I had these mfkers close to me.9 -
The worst thing I have seen a dev do?
- Have all the APIs work without an access token for our main product which handles ~10k requests a day.
- Calling our architecture secure in the crucial investor meeting and being 'confident' that our database can not be compromised. No wonder we did not get funded.3 -
Spent the last month creating a really scalable chat application, with fast front end, all kinds of neat functions such as polls, and a really efficient database structure in Apache Cassandra.. Everything is built to use NoSQL, and even the front-end is using all kinds of features to speed up itself... Now, guess what... The company I'm doing an internship decided that everything needs to be done in MariaDB, and I can basically remove 1/3 of my program, event the front end will get a huge purge of code, and as much as I explained that MariaDB IS NOT FUCKING USABLE FOR A CHAT APPLICATION, and when there are many messages, the access times will get realllllyyy sloow, and that the whole structure there currently is based on NoSQL... Now I can remove all the clustering, custom data types, and bucketing of messages... And store FUCKING JSON IN 'TEXT' FIELDS IN A STUPID SQL DATABASE. FUCK ME6

This one recruiter keeps calling me and leaving me messages on different phone numbers (mixed landline and mobile phones) and I have to block them all.
How unprofessional of an agency to continue harassing a candidate if they're not interested. I've muted their numbers now.
And this is not about being interested either on their side - I know them. They're full of recruiters whose sole purpose is getting their fat ass promoted by use of candidate database and track record filling. One of them even had the nerve to tell me he got promoted and how wonderful it is.
I think I'm gonna make a request to delete my data.
Can you guys believe this?1 -
Database lost connection to the application.
Chaos.
Anybody did anything on the network?
Silence.
Go to datacenter and start reviewing cables.
Nobody touch anything on the weekend? Really? It is not possible...
45min later looking into connectivity tracing... I just overhear:
"I just changed a switch, but nothing else. This is probably the DB having a hiccup."
Ughhhh! I hate our cable network maintenance!!1 -
Possibly the start of a very bad adventure: I'm helping my brother-in-law set up a website for a business he'd beginning with his wife. I'll be needing to provide him a simple cms & shopping cart that he can manage. No payments as we want to just use PayPal so as to avoid having to actually manage user data & credit card information.
Wish me well....
Also advices appreciated cause otherwise, I'm gonna use a simple Drupal or WordPress site with like 1 theme and 0 plug ins.4 -
Dear Oracle,
why do I have to have an X server running for your stupid Oracle Database to install?
Why are you sometimes capable of writing good software like VirtualBox, and then fuck up simple tasks like creating a docker image for your fucking Database? (Seriously, try it, you will not be able to set up a simple Oracle Database using their official Dockerfiles)
Also, what makes you think that -4 is the "most appropriate exit status"?!
What the fuck is wrong with you?
Fuck you really hard you proprietary piece of shit!7 -
So last night a friend randomly found a raw not-yet-installed WordPress instance on a public domain that he found on a Facebook site (it was already linked for I don't know how long, but just not installed).
He told me about it and, being the guy I am, I signed up an account on some free MySQL hosting website, set up a database and used it for that WordPress site.
I then left a kind little note on the front page for the admin telling him that I just saved his ass since others could've done the same but posted racist shit or something and, also, told him not to use WordPress.
Even though I had no bad intentions, I used proxies and VPN connectsions because you never know how these people might react.
Hopefully they'll learn from it 😇 -
When I was really new to JavaScript, I wanted to create an image gallery with images which I stored in a MySQL database. Well, I did not really had a clue how to load all the image sources into my JavaScript to load the images. I also didn't know much about fetching an endpoint of my website to get the data asynchronously.
I also wasn't a good database architect at that time and my database had an image table wich was for the gallery. Within this table there were multiple columns for one image slider (there should be multiple sliders on one page in the gallery (I know... 🤢)).
So I ended up writing an PHP loop wich printed Javascript loops for each row in my images table. Within my JavaScript loop I created the sliders and set the images.
In my defense I can say: It worked. 😅
It hurts to remember this. And I hope you won't judge me.2 -
I had to write a script to clean some crap from a database.
In particular it had some records containing multiple names and I had to split them.
It was really a nightmare because the separator was not always the same, e.g. "John, Mark and Bob" or "Alice+Mary".
«Ok, let's use a fucking regex: ",|(and)|\\+|/|&"»
Then, I realized there were some "Alessandro" in the database. Yeah, Aless(and)ro. Shit.
So I had eventually added more crap into the database.6 -
Working on a database where every column name are acronyms. No, the 2-5 seconds you just saved yourself from typing are not worth it, it’s so easy to make a self-documenting database but you had to fuck that up.1

Our production database has tables that exist only to be recompiled into a single table. Like, one record across 4 tables. Each record is only for one other record in the other 3 tables.
I LOST 2 HOURS DEBUGGING IT BECAUSE IT COULD NOT RECOMPILE THIS FUCKING TABLE. FUCK! -
Dev nightmares :
- Not finding bug fix on stackoverflow/GitHub .
- Losing code that hasn't been pushed to GitHub.
- Dealing with an unclean and inconsistent database.
- Installing Node Dependencies.
- Resolving CORS and 500s.
- Training a Linear Regression Model with 700 epochs on an entry-level Laptop.

Unpopular opinion: unit tests are often overrated.
Although a well written test suite is almost essential in some parts of the application (I.E. business logic) I cringe when I see hundreds or thousands of line which “mocks” everything to test a micro service which just does CRUD operations on a database, in cases like that unit tests are just a waste of time because almost every operation involves a mock which may not behave like the real database and often needs to be rewritten when the code undergoes a huge refactoring. In these case a integration test suite is faster to write and way more helpful.9 -
I was cleaning up dangling images in docker, and I accidentally removed the production database container as well.
Its not a big issue, I can just up the container back and everything should be fine. But after I up the container and connected to the database, I found out there's no data inside. I thought I fucked up, and sent msg in slack channel that I nuked the db.
Later my friend asked me which compose file I am using and that's when I realized I used the wrong config to up the db. Used the correct config to up the database again and everything goes back to normal.
It's friday evening and if I really dropped the db it would be fucking bad weekend....3 -

1. Find a decent, entry level job at a company for full time
2. Graduate from my two year tech school with my degree
3. Apply/start at a university for my Bachelor's degree.
4. Start actually building my database application project. Its been on the back burner for over a year.
5. Try not to be so doubtful or unsure of dev skills. Try being less anxious to ask for advice or explanations, and dont let lack of knowledge discourage or embarrass me from growing my skills.1 -
Beware: Here lies a cautionary tale about shared hosting, backups, and -goes without saying- WordPress.
1. Got a call from a client saying their site presented an issue with a third-party add-on. The vendor asked us to grant him access to our staging copy.
2. Their staging copy, apparently, never got duplicated correctly because, for security reasons, their in-house dev changed the name of the wp-content folder. That broke their staging algo. So no staging site.
3. In order to recreate the staging site, we had to reset everything back to WP defaults. Including, for some reason, absolute paths inside the database. A huge fucking database. Because WordPress.
4. Made the changes directly in a downloaded sql file. Shared hosting, obviously, had an upload limit smaller to the actual database.
5. Spent half an hour trying to upload table by table to no avail.
6. In-house uploads a new, fixed database with the help of the shared hosting provider.
7. Database has the wrong path. Again.
8. In-house performs massive Find and Replace through phpMyAdmin on the production server.
9. Obviously, MySQL crashes instantly and the site gets blocked for over 3 hours for exceeding shared hosting limits.
10. Hosting provider refuses to accept this was caused by such a stupid act and says site needs to be checked because queries are too slow.
11. We are gouging our eyeballs as we see an in-house vs. hosting fight unfold. So we decide to watch a whole Netflix documentary in between.
12. Finally, the hosting folds and enables access to the site, which is obvi not working because, you know, wrong paths.
13. Documentary finishes. We log in again, click restore from backup. Go to bed. Client phones to bless us. Client’s in-house dev probably looking for a cardboard box to pack his stuff first thing in the morning. \_(ツ)_/¯ -

There is this company that saves your information, before you have even registered.
If you merely fill in a field, they will save it to their database. Not even saving/submitting it, just filling it in.
So when you then visit their store, they already know stuff about you (if you gave enough unique identifiers, like phonenumber or email adress) and recommend stuff based on your browsing of their website5 -
Boss at the start of a new project: "We could hire an intern to gatter some data in an excel list... You can easily implement that in the application later - right? So can you get us a excel list to fill out? "
No... Just no...
You tell me what you wanna see and how you wanna interact with the application!
In the process we will figure out which data is necessary, I will build some tables in the database for that data and then, !!! not a second sooner !!! , I'll be able to give you an suitable excel list, which includes a complete list of columns for the necessary data in a form I can work with it.
It's not my job to know what data a application needs to make YOUR JOB easier! I'm not a magician! I just love programming stuff!3 -
So here I am investigating something our users are claiming. I look up which user the UserId did the change and I see not only the user but also the users password in clear text in a separate field. I thought that field was for a password hint that the user can set up, but I asked around and apparently, no... It's literally the plain text version of the password stored in the database, next to the hash of the password.
Apparently, the users were so impossible to deal with that we added that column and for users that constantly pester us about not knowing their password and not wanting to change it, we added a plaintext password field for them :D2 -
3 Database SQL walked into a NoSQL bar.
A little while later they walked out.
Because the could not find a table -
Uhm, that's not how it works GoDaddy.
Apparantly it takes 2 hrs to bring a website back online (which went offline simply because the database was larger than 1 GB) after the DB size has been reduced... And that's exceeding my expectations!?3 -
Oh no 😱
.
So I have a database with 12 tables, It grows really slowly and it's not really important, so I just do a manual backup once in a while.
.
Today, I wanted to do a backup, and realized that the content of the only table I cared about has disappeared.

I miss you Data, rip7 -
Not have privileges in prod database, so i have to create a simple 'hidden API func' in the backend of apps that i develop, so it can receive raw query and give response for the results, the REST API is (/getReport). Still Works :/2

I've been assigned lots of database work the last couple of weeks. Managing old databases are what make or break people surely.
The customers have this proprietary mess of a Visual FoxPro database manager.
I spent the entire day navigating what I should and shouldn't export for them (as they're fortunately trying to rid themselves of the service)
When I was supposed to do the export, the proprietary hardware only allowed exports of 25 rows at a time with the free version this big company is using... I ehr... I just regret not converting it into SQL to begin with.2 -
One of the largest companies on the continent. Uses Oracle on AWS RDS with the beefiest resources available. It comes to the point where lowering the number of CPUs boosts the DB performance up (concurrency). Point is - Oracle is sweating hard during our tests. You can almost feel the smell of those hot ICs on AWS servers.
And then someone at higher levels, while sitting on a pooper, has a great idea: "I know! Let's migrate to Aurora! They say it's so much faster than anything there is!"
*migration starts*
Tests after migration: the database on the largest instance possible shits itself at 10% of the previous load: the CPU% is maxed out (sy:60%,us:40%), IO is far, far from hitting the limits.
Is it really possible Aurora will cope with the load better than Oracle? Frankly, I haven't seen any database perform better than Oracle yet. Not sure if it's worth to invest time in this adventure..2 -
Just had a recruiter contact me, and found this gem in their text:
"We work with MS stack and SQL Server, but we really think JavaScript is the way of the future"
Motherfucker, JavaScript can hardly tell basic types apart, how the fuck you gon' run a relational database with it!? And if you're not, then why the fuck are you running a relational database in the first place!?
Fuck outta here!2 -
this year i finally found a job where I don't feel like dying, and it pays well. things are going so smoothly that I'm a bit weirded out, in a good way.
the work as a dev requires creativity and is mentally exhausting, but i got a nice routine going on (not a lot of programming, mostly database maintenance), and even with the high pressure I'm still fine :) -
I have multiple contenders ;)
Contender one:
A program used to sort emails.
We was in the process of moving from lotus notes to exchange and needed a way route emails to the right server internally.
Solution, a qmail to receive all emails, a script running by cron every minute to read the emails, check the recipient name to a list and resending to the right server. The script was written in php :P since that was the only way we at the time had to read an email into an object, it was run just like any other shell script :D
Contender two:
A multi threaded mail sender that fetch email addresses and content from a database and posted them through qmail using background execution and pipes to get the result back and then update the database, written in bash script.
Contender three:
A c program used in a similar way as in one but this time using dial up and uucp to fetch email and then drop these either into lotus notes or into a bbs for our customers to give them an email address. This was around 1993, so not to many isp’s offered email and not to many had internet anyway, dial up bbs was much more common.5 -
When a vendor tells you you can't do certain things on their API because their database is not optimized, and then drops the bomb that doing a certain action that, when it happens to overlap with a completely different client doing the same action, causes their system to go down, you know it's a Tuesday that feels like it should be a Friday...

So.. name one fucken case where your database is not a computer backed thing.
Just asking because.. why the fuck? I don't think your database server supports input of fucking math symbols? JUST USE HUMAN LANGUAGE, AS YOU HAVE TO DO ANYWAY!
It's stupid how everything needs to be expressed mathematically ffs. Not that it's hard to understand - it's just more complex than of a very simple wording.5 -
A programme I have to maintain (and not allowed to optimise or change):
1) read input from serial connection
2) store data in MySQL database
3) every day convert to CSV
4) store on Windows file share
5) process CSV in access 2000
6) store in MsSQL database
When it was first developed, I said to te developer to store it straight from serial to MsSQL but out boss wanted it to follow the above spec.
He has now left and I have to maintain it1 -
Export data from a database that you've not modeled is a problem (sometimes), I just realized that this DB has two tables to storage cities, the main difference is the id, the other fields are the same in both tables, I hate that kind of people....

Finished a complete version upgrade with vastly improved scalability and maintenance in just 3 weeks!
NO!
I forgot to do the database migrations as I went along. Ok... no problem.. I'll just use some kind of database comparing software, I'm sure they exist...
<googles...>
...fuck... is there not any for free?
Ok fine whatever i'll manually compare the tables and columns, fuck it. Sure there's like 50 tables and like 20 columns per... whatever...
should take like a day or so, with testing...
YES!
Finished my new version upgrade after just 6 weeks of coding!

Hello not a rant,
Are there MS SQL Server admins here who self taught and learn thru self study?
I work in a company where they use MS SQL Server as the database. I would love to 'understand' how to write efficient queries, and how things really work, not just selecting and joining table blindly and not understanding how things work.
Would you recommend how you understand MS SQL Server, or what learning path you took?
Thank you. I would appreciate any suggestions and comments.10 -
First time programming for work... Man in the middle student password changes. Yep that's right I'm being asked to write a program that will change students passwords on their Google accounts and local domain while also keeping a decryptable format password in a database. Granted it's much better than not letting students change their passwords at all. Plus were doing it because it will let us fix their issues while their out of school so...8

A few minutes ago, I was going crazy over a bug caused due to data mutation in Rails.
Basically, user1 was creating a post record and it's stored in the database normally however, on page reload for a second user, user2, the post (that user1 created) was update to belong to user2. This is because, on page reloads, I was using `<<` method call to append user2 and user1 posts together! Apparently, `<<` not only mutates the array, it also performs a database update.
Kill me please!!
Also, data immutability seems a more reasonable feature in languages now.1 -
Had to fix all bugs of my colleague this night because our client was not happy.
Before he joined us he worked as a database admin and now he wants to learn web dev and coding. But he did so bad mistakes like endless loops or requesting api 5 times.

Working at a local seo sweat-shop as "whatever the lead dev does't feel like doing" guy.
Inherit their linux "server".
- Over 500 security updates
- Everything in /var/www is chmod to 777
- Everything in /var/www is owned by a random user that isn't apache
- Every single database is owned by root sql user
- Password for sudo user and mysql root user same as wifi password given to everyone at company.
- Custom spaghetti code dashboard with over 400 files in one directory, db/ api logins spread throughout these files, passwords in plain text.
- Dashboard doesn't have passwords, just usernames to login
- Dashboard database has all customer information including credit card stored in plain text
- Company wifi is shared by other businesses in the area
I suggest that I should try to fix some of these things.
Lead Developer / Tech Director : We're an SEO company, not a security company . . .7 -
To a fellow dev on my team; If you notice a difference between the spec and the database structure, just fucking talk to the BA! Don’t code something that fails and put it into QA.
And constantly saying “It’s not my job” is a severely career limiting move you dogmatic little shit.2 -
In PHP, constants can only be of simple data types like strings or floats.
You can't make a database connection a constant because it's not a simple data type.
That makes the only way of accessing complex "constants" within functions using the keyword global... which is not encouraged and forces you to make the database connection global (that may not be convenient in some software patterns).
The last option is passing the database connection as a parameter (either to the function or to the constructor of the instance whose methods will use the connection)... which would be good if I didn't want to go full OO. Because it's a pain to do so.
So all in all, constants are not well supported by PHP.
Come on, constants...12 -
Mine: not listening to early warning sings that shit won't work. As a result we implemented the wrong technology and had to roll back after a month in production. Lost some customers data, though we had backups, so it was just a delta of a day or so. Still, not pretty, had a rough night writing scripts at 3am to check data validity after.
I will throw in another one from a colleague of mine. He was running some database migrations and ended up pointing the DB migration tool to production by accident. Oops. That one required a restore as well, if I remember correctly. -
Recruiter bot just emailed me with some offers, let's take a look...
"Hand-on Experience with SQL and NO-SQL Databases preferably Redux"

Soo... Let me get this straight... My boss reeeeeeally wants me to reconfigure our database system to sync data between each of our 15 sites... Let me this about this...
Our database is an MS Access database originally written about 17 years ago. It was written as a standalone database that runs a unique instance for each of our sites.The person responsible for the database (still not the original developer) before I took over 6 years ago bragged about how they were "an 80s developer" (w...t...f!). Even with all of the fixes and additions (additions because... F&$#ing of course there are!) It's still basically held together by duct tape and spit.
Hmmm... Ok, still possible. What's the environment I'm working in... I have absolutely ZERO control of our workplace network... That's a whole other department. Due to the nature of the workplace (and it's sites) there is extreme limitation on network access.
Well... If I'm Reeeeeeally nice to the people in charge of the network, maaaaaybe they can give me access to a little server space.
A very long shot, but, doab.... Oh, the boss would really like this handled in the next couple months...
F$#k you! There is no way on God's (still) green earth that I... Alone... Can rewrite a legacy database... written across 4 or 5 different versions of FU$KING MS Access, and give 15 sites, with extremely limited networking, real time data sync in... Oh, a few months.
Now, I do not work with "computer people". I'm usually lucky when my coworkers remember their passwords (which, even if they don't, WHY tell ME! I don't run the network!)
And when I tell my boss basically what I just said... In a nice, pleasant way... They suggest I'm not giving the problem enough thought...
FU#K YOU IGNORANT ASS! Write me a ToDo list in MS Access (no, I'm not going to tell you where to start) in under an hour then, MAYBE, we can talk about... No... Just NO... Can't be done!
*Takes deep breath* so... Lovely weather we're having, right?3 -

Client be like:
Hello,
could you please restore our database from today's backup?
At a first glance - nothing out of the ordinary. Daily backups are standard...
Until we get the backed up snapshot running.
MySQLDump is somehow... Stuck. It... Doesn't seem to be doing... Like, anything. For ages. Wtf.
So we check the database. Connect, change scheme and... The commandline tool gets stuck, too. Weird.
So a layer lower, we check the datadir and... ls... After also getting stuck for a bit, lists about 500k files O_o
Yea, dumping a database with roughly ~250k tables is not fun. No wonder it takes ages.8 -
So here I am trying to understand the database schema in order to write a REST interface. Then I find that one of the tables contains an id and a name columns but the name is Integer not a string!
I contacted the developer who gladly explained that it was easier for them to store the ids in the database but the actual names strings were hard coded in the source files so they can handle translations! -
Until today, I had assumed deploying stuff to prod would NOT be one of my responsabilities in this company. Apparently that's not the case.
Had to deploy my code and pray it didn't break anything. Why is this a big deal at all?
Well you see, there is no repository. At all. No git, no svn, not even duplicate folders. No tests, no pipeline. Just a bunch of CPanels.
Had to manually copy files and folders from the development site to the production site and partially copy a database. "Just drag and drop" were the instructions I was given.
As if using CakePHP2, PHP5 and having to parse fucking Excel files wasn't bad enough, now I have to deal with one of the worst ways to deploy code.
Fuck it, I'm switching on the looking-for-job flag on linkedin.5 -
Me: Ok, this sounds like a good idea, however we need to consult the Act to ensure we're not breaking any laws by requesting this new information and making it mandatory.
Boss: I am trying to ensure good database management and data design principles, why can't you just agree with me?
Me:... I agree with you... But changing up the process like this may put us in hot water, let's just check to ensure we're good on the legal front --
Boss: The law is just a guide. My primary concern and your concern should be the design of this database and ensuring we stick to good data management principles!
Me and other technical staff: 👀6 -
I think that was that automated greenhouse thingy.
This is basically a Raspberry Pi with sensors, a fan and a water pump controlling the air circulation and watering of the greenhouse. The data from the sensors gets stored in a database and you can check the temperature & humidity history on a shitty web interface.
This was one of my very first projects and I'm really proud of finishing it although it's really not perfect. When I started it I had never worked with
1) databases
2) sensors on the raspi
3) webinterfaces
before and somehow managed to get it working.4 -
Just got handed a dozen servers. Documentation shows a (Linux) database cluster is using ldap authentication. I try logging in with my creds. No joy. I look up the root password and log in.

Hello,
I just quit my job at a big market research company. It was disturbing how much processes there depended on excel and obscure visual basic scripts.
They load data from a database, do typical database tasks with excel and upload it back into the database.
PhDs run complex statical computations through an excel interface that passes the request to R.
Instead of an hour Python they execute stupid tasks with excel by hand. Day after day, month after month.
WHY? My colleagues were not dumb but instead of learning SQL and some python they build insane excel tables.
Maybe it's time pressure. But this excel insanity costs much more time in the end.5 -

Wasted half of the Weekend to Setup MySQL on my vServer which uses ssl encryption, have specific User and so on.
Thought: well, the User mysql is not so good as a Name. Drop it, you don't need it.
What did I? Instead of Drop User mysql , I typed Drop Database mysql.
Fuck that fucking Shit. I'm so sad right now. Broked the complete MySQL Database. Nothing is working anymore. And the server is new, I've Just made One Backup. Deleted this a few hours ago.. also accidently.
Help me :( Shit :( so sad :( Now, I don't have Motivation anymore to work with the vServer :(3 -
So, i started at this company about 4 months ago. So far i mostly worked in existing project and legacy code.
We started a new project for a pretty big client, and i'm the one who's responsible for setting the project up. The last two days i've been struggling with database issues. Finally got the site running locally about an hour ago.
And now i am running into troubles because i don't know how to set up a project yet since i only worked in existing projects.
Great. Can't say i'm not challenged here! -
Hey there people, I have a few questions regarding neo4j. Your experience could also be very useful to me here @dfox.
1. Is neo4j good for storing user data, like password hashes, etc.. In addition to the regular relationships with other components of the ecosystem
2. Is neo4j good enough to accommodate a really large number of users..
3. Does DevRant use a dual database, like user info in Mongo and relationships like comments and ++ on neo4j or is it like everything on neo4j
For q.3, if you're not @dfox then just provide an idea of how you would handle the situation.7 -
I am programming a site where developers can share shell scripts and other users can execute it via a CLI.
I decided to add a little joke into it: the page where users can view a shell script is https://mukodik.com/scriptid.sh
I use Express, so I just use app.get('/:id.sh') to get the scriptid.
How would someone possibly bug out this page? (the uploaded shell script is not actually stored in a file, it's stored in a mysql database(using connection.escape to escape chars))2 -
The customer wanted me to create a password for their database. I made it the name of the software and appended b4lls.
Whenever I tell him what the password is I spell out the software with the b at the end, say "the number four", then lls. He has never repeated "oh, softwareballs", I am not sure he has noticed.1 -
To solve an issue of slow data retrieval on an app, I suggested pre-loading the data once a week and storing it in a spreadsheet ready for instant download.

Domain Drive Design question:
I am working on a simple case to teach how to apply DDD, my case is as follows:
Simple forum with Author, Moderator and Users.
I am using Dotnet core for this. I am not sure how and where I should implement authorization:
1. Author can edit his posts only
2. Moderator edits any post
In dotnet core, we handle roles, policies in the api layer, and its per endpoint, I have an identity layer which handles accounts, registering roles and policies in database.
But I'm not sure if I should or how to handle authorization based on permissions in application layer.26 -
What's the actual requirements to be called full stack developer? I do front-end, back-end, database, server, my own api's etc. I even have a t-shirt with "Keep calm and hug a printer".

I’m either going crazy or someone just dropped a table from a database I’m actively working in. I don’t have a drop script for any tables in my code, not anywhere. One moment it’s right there, the next it’s gone? Luckily it’s pretty much empty, only generic data. On my way to check permissions.6

I don't care if you're a Senior Developer. You just make me look dumb adjusting to your needs of not normalizing your database queries.
We agreed that a restaurant can have many items, but instead, I get "an item has many restaurants" relationship. Geez.2 -
I'm still not over how LINQ is defined as a thin wrapper over both IQueryable (which can be efficiently queried) and IEnumerable (which can only be iterated), but IQueryable extends IEnumerable, so if you execute one unserializable operation anywhere in a query issued to your database it'll merrily pump whatever temporary collection happens to reside on the boundary through the C# program to execute that call on each row and process the rest as an IEnumerable.5
-
Not sure if it should be a joke or a rant, but something rather funny (at least to me) happened today.
TL;DR; Someone's outlook was crippled by 100k+ of warning notifications
So we have developed a server that has an internal database that wraps around an elastic search instance, that is managed by a POS vault/storage solution, that we have to use for legal reasons. The elastic search is "provided" by the software, but we keep this internal database just to be sure and totally not because it's unreliable POS.
Anyways, they take data integrity very seriously, so every warning our server produces is emailed to someone in charge to review it and if necessary forward it to us. This will be important later on.
Couple of days ago we got error forward when trying to write an entry into the POS software we get an error, because an object we tried to write already existed. After some investigation we concluded an entry was missing when the internal database was created, so we asked them to repopulate elastic search to solve this problem.
When start the server we always sync the internal database to the elastic search and emit a warning when an entry is missing in internal database or vice versa. And well... almost all of them were missing, which caused our server to emit ~40 warnings/ms. Poor outlook. Still investigating for the cause, but damn, I never expected I'd take down someone email account by accident -
Anyone else here who needs to deal with GDPR on the software level? I'll go nuts until we're compliant in every aspect.
I've been developing a consent library for the last few days. It even automatically links expressions of explicit consent to current screenshots of the relevant forms (because you need to do that too), and past records are immutable. Well, unless the whole database gets fucked somehow, then it's not.3 -
I was working for a project with one of the project managers. Despite several discussions, he was not ready to have provisioned for procurement of couple of extra drives for database backups. Also because it's always how they worked, developers were allowed to make changes to the production databases directly.
Since I knew it was going to be burning some day, despite his negligence, I ran a script to take full database backups every night, compress, and remove old backups all to do in the drives we had on server. Sat it automated using scheduler.
One day it happened that one of the junior developers deleted one major table taking whole production down. Next thing you know everyone went crazy. Since I felt bad for the managers and users, I was able to restore database using backup from last night.
You know who jumped in first before senior management to take credit of all this and got some nice kudos..that project manager. Also, you know who got burned..it would not be a rant if I did not got schooled for not following on the wisdom of project manager.
Anyways, we are still not taking database backups (as per project manager) -
I was trying out flutter because why the fuck not. I made a plan for an application the downloads an Osu!-beatmap file and extracts the infos relevant for an external music player (like background, the song file, title and so on)
So I designed a basic database scheme and decided to include the files into the database. 3 hours into development it hit me...
HOW THE FUCK IS THE EXTERNAL MUSIC PLAYER SUPPOSED TO GET THE AUDIO FILES WHEN THEY ARE IN MY DATABASE!
Guess I'll just have to replace the files with absolute paths instead. 😒 -
I really hate the term fullstack developer. Just call it what it really is. Javascript react developer who dabbles in node occasionally.
If you don't have some knowledge of tuning a database, tuning your runtime, handling issues with networks and latency in your code, dealing with issues with message queues, writing abstraction layers for the database, etc. you aren't a backend developer, sorry to say.
Being able to reason about a mean stack running on digital ocean doesn't not make you proficient in the backend.3 -
JQuery is not badly designed... It's not designed at all.
JQuery is just awful and it's being used by people who know nothing about programming... Hell, some of the JQuery developers were not even programmers or had programmed before.
JQuery is a part of the whole "Wordpress community/world" and that world is full of people who doesn't understand what they are doing, Wordpress isn't designed either (that's why Wordpress stores serialized data in a structured database).
Every single Wordpress theme developer includes JQuery and it's disgusting. Most of the time, they don't even use it.
JQuery is not Javascript on steroids, it's javascript with cancer. Get rid of it. It's bloated and only lazy people use it. (JQuery will give you about 200ms extra response time for your site)5 -

Hm. in MySQL 8.0.23 (yeah I'm kinda slow at catching up) they changed quite a lot.
- Hash Join implementation
- invisible columns
- InnoDB behaviour, eg AHI / IB

https://dev.mysql.com/doc/relnotes/...
https://dev.mysql.com/doc/refman/...
Guess no more MySQL for me.
How should I trust a database whose QA seems completely non existent and where minor version releases change the complete behaviour of the database....
(it's not new per se, Oracle announced that with the 8 GA release minor releases can have new features, but I'm surprised they really keep it up with breaking... Their QA sucked before, but with the new features coming, MySQL / Oracle is dead to me. )
Will be interesting to see in which direction Maria DB goes.... So far it looks good, although they really should think about cutting ties with Oracle / MySQL as a lot of internals have quite diverted....
Fuck Oracle.20 -
It's too early to be asking these questions today:
Are your DB schema changes checked into source control?
What branch are they checked into?
Why are the schema changes checked into one branch, but deployed to a completely different database?
Is my CI pipeline deploying incorrectly? Oh, you manually deployed changes.
Are your DB changes in source control an accurate reflection of what you actually put in the staging database?
Why not?
Can I just cherry-pick update my schema with your changes from the staging database?
Why is there a typo in your field name?
Oh. Why is there a typo in the customer data set? Don't they know how to spell that word?
Why is the fucking staging database schema missing three critical tables?
Is the coffee ready? I need coffee.
Why is the coffee not ready yet?
What's going on in DevRant this morning?
What project am I working on now anyway?
Did my schema update finish yet?
Yup, it finished. Crap. Where the hell do I keep those backup files?
What's the command line to restore the file again?
Why doesn't our CLI tool support automated database restores?
I can fix that. What branch name should I check the CLI tool into?
What project was I working on this morning again?1 -
So, i'm trying to get linkr (a pretty cool short link service) to work in a docker container since 4 hours now to host it on my server. There is no official container because it needs a working database connection and stuff during installation which can only be done via console and (for whatever reason I couldn't find out yet) need to be done while building the container. The problem is, I can't connect it to the database while building the container so there is no database during installation to create tables and stuff and the build will fail. ARGH.
Why the hell would you do this????? Theyre actually saying in their readme there is no dockerfile because the config options are specific to your configuration...?!?!
The thing is entirely written in python, so reading and parsing configfiles on the fly should not really be a problem.
Of course I could ssh into the container and run the installation script but that's not the point.
Docker is not about being lazy.
It's about portability.
Maybe I don't want to bloat my server with your 39579372639 npm dependencies? Or I don't want to install a freakin apache, because I have every other site on nginx and therefore wouldn't work with apache.
AAAAAAAARRRRRRGGHHGGGGG
in the end, I'm probably going to modify the thing to install tables when running the container and giving the first user admin rights instead of prompting to enter credentials for a new admin user.
And yet I didn't even speak python. -
Im on it, all my rants refere to it:
780 columns table, pushing unfinished changes to master and recently the new hire pushed a 700mb database bkp to production... I had to learn how to clean that shit on git and rebuild the repository...
How can someone not realize they are pushing 700mb to gitlab?
That shit must have taken ages... I realized because git pull was taking too long... -
Am working on a chat module for android using firebase realtime database
Everything is working fine but am really confused how to select that this message should be sent to a specific user not to every single logged in user
Can someone help me with this?4 -
Hmmm, so you’ve used the DAO pattern everywhere so you’re not coupled to a particular database, but you don’t mind having 8 lines of Hibernate annotations at the start of an entity class, and 2-3 annotations on every property.

Last week I did a test for a huge real estate company here in Dubai.
The test they asked to create a database of students and use jquery datatables so far is easy.
But they told you cannot use any framework and uses mvc structure, in other words, build your own framework. It's ok.
But my main concern is, the company is quite famous to not provide proper feedbacks or just forgot about you. And I would be very piss off if after of 3 entires days building my own framework, doing documentation, code comments those guys didn't reply me any feedback.4 -
I eagerly wait for the day some people will realize and believe that Hadoop is a file system and NOT a database!!

If, as a Dev, you have not heard of BAYOU, you need to research it, especially if you live in an area that can afford the initial investment. I think this AI technology will mature in less than a decade.

I don't think this will be limited to software development either, I think this type of AI will lend itself equally well to database development. We live in a technologically exciting, if somewhat unsettling world.5 -

Mf php and mf mysql database. Fuck you for being such a cunt.wasted my whole fucking day to configure the shit i didnt even broke. All i wanted from your ass was a storage for users but no you piece of shit. And a fucking special mention for php bcz that shit is a stinky piece of work.

So.. I'm migrating a physical server to a virtual (Hyper-V) one.
The physical server is running Windows Server 2008 R2 with IIS6 and Windows SQL Server 2012.
I've set up a VM with Windows Server 2016, IIS10 and Windows SQL Server 2017.
I'm testing with just moving 1 db at a time (we have about 20, 1 per client running this software and a few others) and I've already imported all of the IIS sites.
So the database import and IIS import went smoothly and was surprisingly without hassle but now I'm trying to run the website that I imported the database for and it is throwing 503 Errors at me.
I've been trying to find out the cause but for some reason IIS isn't making any logs.
It's not any 64/32bit system problems (they're both x64) and I can't seem to find anything wrong with the imported config.
Anyone got any ideas?14 -

Fire every single teacher who runs from self education. Someone who keeps themselves up to date should be keeping students up to date.
Secondly, assign each class a major project which starts from 4th semester with one of the faculty acting as the Project Manager. Allow each student to choose their area of interest and work on that module. This will help develop team work and teach how not to rm rf production server or db:drop production database ^.^ -
Hey guys,
can you recommend a graph database? I already tried orientdb but was really disappointed. The performance was quite good but I stumbled across a lot of bugs during my tests (even managed to corrupt the database during normal operation). So I am looking for a graph database that's a little bit more mature. I heard a lot of great things about neo4j..but I am not 100% comfortable with the license costs. Are there any alternatives?6 -
I've been wondering for a while about something...why do so many devs complain sooo much when they have to to stuff not related to their main area of expertise.
I like learning and trying everything if I have the opportunity...backend, fronted, database, dev-ops, crypto, networking, virtualization...I stuck my nose in everything...but I see a lot of people moaning and despairing when they are thrown out of their comfort zone.
Like why...it's interesting... it's not always sunshine and rainbows but knowing something new in IT is never gonna hurt you...who knows maybe someday it's gonna help you get out a tight spot or land that awesome job you wanted.
Ok I'm done 😁11 -
I've been working in web development and design since 2012 and, while I've worked with others in my field along the way, I've not forged any lasting friendships... maybe I'm just a shitty person? I've burned some bridges that's for sure. Anyway, it all boils down to: I have no one to bitch to when I want to stab someone in the abdomen over frustrations at my current job.
Enter devRant...
I'm coming up on the year anniversary at my new position and there is still a lot to take in. I replaced a "web guy" who had been doing it for 20 years. Anyway, his stuff is all a mess, and what's worse is that the problems I'm seeing stretch far beyond my own responsibilities. I'm in a group of "tech" people who have all been here for a decade or more, and they're almost all like the guy I replaced: set in their ways and years out of date.
There is one gentlemen who is managing a database application and each site links to his ASP (not .NET) pages. Each of these pages looks like the website they were linked from. He showed me how he achieves this and it's just insane - he uses a bunch of files (basically just text files) that make up different pieces of the page to recreate the look/feel of the website on this his server - just to serve the information from the database. God forbid the website changes 'cause then all his little files need to change.
When I suggested that I can just query the database myself and display all that information on the actual site instead of doing all these redundant steps, I get "I think we should stick with the way we've been doing it for now."

Is it just me, or do REST API's literally rule the world right now?
Feeling like I can automate the universe.
But this is a real question. Are there reasons to avoid using web API's rather than sending data through some kind of shared database? I guess I'm not even sure what the alternatives would be right now... Are there disadvantages I should know about?3 -
What use is a frontend developer (having exclusively frontend development knowledge) that's not a designer / isn't good at design.
Sorry if I'm being harsh, but you're either a web developer, knowing how to build web apps (or websites, or whatever), or a UX developer or whatever, knowing how to do pretty (and usable and accessible and...) things. Or even both.
Lemme say it differently. You either come from a web design and build a frontend, or come from the development of an application (database, logic, architecture, APIs, etc., backend++) and build a frontend for it. Again, or both.
Not being able to design, and not being able to build a product, is just... nothing? You're in the middle.
Sorry, but I don't think you're a developer. Maybe a coder.11 -

Had trouble to connect to our MySQL database, so I decided to open a ticket to the Database admins. At least they are pros and I'm sure they'll help me:
"Hey guys, I have trouble connecting to [Hostname]. I guess it's a firewalling issue would you take a look? Attached are screenshots, saying hostname not found.
Answer:
Hey Dominique, are you sure the password you used is correct? Is it yours or the sysuser pw what you sent to the server? How did you send it?
Me: (kind of confused) Hey dear admin, did you look at my error message? It says Hostname not found. What do you think how I provided any credentials?
Support: yes, I saw your screenshot and don't see any password entry. That's why I asked!
Me: Well, than... ok... go and search for another job. Yeah and consider fucking yourself. Kisses. -
2 AIX workloads got messed up during patching. Apparently they had a local database and they were in PROD env.
"Not a biggie - there's always a netbackup to restore the whole workload" - I said and reached out to netbackup folks.

Mini witch hunt going on with broken builds last couple of weeks. Change satellite assembly/project A, breaks random unit test that hasn’t been changed for months and the TFS nazi sends out emails demanding the “broken” projects be fixed. Doesn’t matter the unit/integration tests are likely out dated and team responsible for the tests needs to fix it.
Yesterday I deleted some logging code out of a security assembly, broke an integration test that hasn’t needed to be ran since January (test database didn’t exist anymore).
I would have had to re-create the database, re-import the test data (not trivial), re-deploy a service using the test database…blah. All because I removed some logging code.
I deleted the gated check-in TFS build definition. Code check in … no sirens …whew! I win! -
So we finished our requirement ( barely) for a new client. Next is data modelling and system design.
We started with data modelling. Unfortunately the lead developer does not know the difference between database and data modelling.
me: hey bro, we'll do the database and stuff later, now let's focus on data modelling.
him: (acting like he knows) yeah I have developed a sample design for the "data model".
me: no this is database design.
him: what's the difference?
me: dude, they're totally different. Okay, simple explanation data model is what you want to store, whereas DB design is how you store it.
him: So, if I am not wrong, it's implied that you know what to store if you are talking about how to store it.
me: but you don't know what it is you want to store yet. And one of them precedes the other.
him: Okay, let's start with DB design.
me: What?????? you want to build a house without a plan??? That's it for me I am done !!!
I left the project yesterday, later I heard that, the team members are coders, who think that developing a software is all about coding and fixing errors. -
Pulled my hair out over one today (and a week ago when I first saw the issue)
Setting up development environment. Created test user and test database and used mysqldump to copy data over.
MySQL was executing a function as the wrong user. Checked my config files, checked my config reader, checked my database connection, checked checked checked. Checked everything twice, I felt like Santa.
Changed the password in the config file to make sure it was logging in right. It threw an error still but not one I had expected so I figured the login still worked (My bias was that I thought the config file was not working or the mysql library was caching authentication. Both were wrong but this blinded my debugging. Foolish, I have forgotten my training)
Logged into the database directly via client. *didn't bother executing the function because I was only testing auth*

Search entire project for database username. It's gotta be hard coded by accident SOMEWHERE.
It's not.

-- Flashback to how the test db was created -- What's actually in this damn script?
DEFINER `production_user` CREATE PROCEDURE `old_db`.`procedure_name`
Two issues: definer is old user (this is the error I was seeing) and its creating the procedure on the old db (this would be the next error I would have found if I kept going)
Fuck mysqldump. Install mysqldbcopy. Works
Put hair back in head. -

This one time last year a colleague found out that some data went missing and suggested to recover the data from a backup. When trying to create a new database instance in the Google Cloud Platform (if everything works it's amazing!) it failed.
Not knowing why this happened, I tried to revert that backup to the production database, after creating a backup using the GCP. Needless to say that failed as well, resulting in a corrupted database instance where I couldn't access the created backups anymore.
This all went at around 10pm and the only users of our product are currently in the same timezone and use it from around 7.30AM until 6PM so no one besides our team knew the server was down.
After a long night chatting Google's support team the database was successfully recovered and the only harm done was sleep depravation for me and a colleague.
Apparently there was a bug in the GCP. It was resolved in two hours and the last time a breaking bug was in that piece was more than seventy days earlier.
I did at least learn to create local backups as well, instead of relying on the tools of the same product...
Best: the moment I saw the corrupted database spin up again and not losing my job because of it. -
At what point can you say you are experienced in x language?

Our site has a feature where if a user changes some parameters in his profile, his plans on the site are updated in accordance with the change.
It took me a 2 weeks to implement a proper queue based updating mechanism.
My manager : "What's taking so long? Why not implement it in a recursive loop of all the users in the database?"
I could only stare with my mouth open. -
Me: Why is the record not there? Why? Why? Does this database even work?
2 mins later: Damn. I had a "limit 10" at the end of the SQL. -
I love it when someone wants you to troubleshoot an issue but will not give you a test user account to test with. So you have to sit with a user or talk with them over the phone while you troubleshoot. I'm literally elbows deep in the code and database, but you won't give me an account for security reasons. Ok, that makes complete sense.

Deadline was 2-3 days for product launch and doing distributed transactions was not an opinion as it requires heavy modifications.
I was doing money transfer app between one transactional system and one not transactional system so the way I did it was :
1. transfer money from one system to my app that was using Akka STM ( software transactional memory)
2. try to transfer money to second system
3. transfer money back on failure
There was no database, no state only transactional log as installing database would require to much time and paper work.
Sometimes transfer back failed so we need to look back at logs and search for money, it was quite easy cause there was error and there were not so many failed transactions like this.
About one or two in a month and everyone accepted that.
I started to write some sort of reconciliation thread but then was assigned to other work and it worked like this for couple of years transferring couple millions worth of transactions.1 -
Was working in an n-tier website, standard Web forms, BAL, DAL, database architecture. Validation and processing of data done in the BAL. Not the best idea, but whatever. Well apparently some developer thought it was too much work to pass his data through the BAL, so he directly accessed the DAL, performing zero validation on the data being passed in. Luckily, this was in a non-critical part of the site but the PM at the time nearly had a heart attack when I told him.

A database fetch. All rows at once. Not that many rows, maybe 50.

Most fun I had coding?
I was developing my first android app and the database accounted for all the weekdays.
It was a night and I was coding. I build the app after 90 minutes of last build. I was fucking amazed to see that my app was running perfectly on Genymotion Emulator whilst the same god damn build crashed on my phone.
As a new novice developer, I thought it could be due to the OS version difference b/w my phone and VB.
I went on to spent an hour or so, to figure out where I had gone wrong. I re-read my code multiple times and nothing. I could not find a single error in the code.
I was fucking speachless when it hit me, FUCK, today is Saturday (last build was around 11PM Friday) and VM's time is usually screwed (it was Wednesday there) and since I had not accounted for weedends entry in database, the app crashed.
It was really fun having this sort of a bug for the first time in my life. Solved it within minutes after that. -
I'm still on a regular basis reminded of how I might be wrong despite the absolute certainty in how obviously wrong the other person is.
Lately I've been working on setting up this API with a fairly intricate database integration. One request can lead to multiple db calls if we're not careful, so we have been polishing up the implementation to guard against ddosing ourselves and dealing with thread-unsafe concurrency.
Someone on the team could happily report that they got rid of all async use so there should no longer be threading issues. "You mean it all runs sync now?" "I guess. It works at least".
I'm just internally pulling a surrender cobra. If this was pre-dev me I would have let him and everyone know what a stupidpants he is and that I thought he had some experience in api development. But let's not make an exception to the rule; I might be wrong. I mean I'm not, but let's pretend I could be. Let's pull down the changes and maybe set up a minimal example to demonstrate how this is a bad idea.
Funny story. He got rid of explicit calls to the database entirely. When resolving data, the query is instead constructed virtually and execution is deferred until the last step. Our functions are sync now because they don't call the database, and threading isn't an issue since there's only one call per request context.
Thank god I've learned to keep my mouth shut until I can prove with absolute conclusive certainty that they are wrong. Here's to another day of not making an ass of myself. -

Sooooo I came in to work yesterday and the first thing I see is that our client can't log on to the cms I set up for her a month ago. I go log in with my admin credentials and check the audit logs.
It says the last person to access it was me, the date and time exactly when we first deployed it to production.
One month ago.
I fired a calm email to our project managers (who've yet to even read the client complaint!) to check with ops if the cms production database had been touched by the ops team responsible for the sql servers. Because it was definitely not a code issue, and the audit logs never lie.
Later in the day, the audit log updated itself with additional entries - apparently someone in ops had the foresight to back up the database - but it was still missing a good couple weeks of content, meaning the backup db was not recent.
Fucking idiots. -
After all this time I’m still confused, why was Cambridge Analytica such a huge deal? I feel like a lot of people knew this in years prior, that Facebook/Google were scraping user data and activities to use for personal profiles and hence more directed as placement. Stuff like Ghostery, Privacy Badger, Disconnect, Ad Nauseum (rip it’s Chrome plug-in) etc. all focused on not allowing these same trackers to get information, so not like this case just magically busted the doors wide open screaming that all those websites you visited are now in Facebook’s database and no one knew.
I just can’t quite understand why everyone got up in arms after this.1 -
We had a test in class where one of the questions was "What is SQL injection?" and I wrote what it was and even gave a bang on simple example where I showed how you could end up with a truncate statement on your customer db. The last part of it was:
"This will be the SQL that gets executed:
INSERT INTO Customers (Name) VALUES (' ';TRUNCATE Customers;--);
When I got it back after we had a session of "grade each others work" I got the comment: "What makes this an attack against a database?"
I mean, I'm not sure what I could have written. That it truncates the database? And, correct me if I'm wrong, but if a user truncates your DB, is that not an attack? -
Today I discovered that Betheme for Wordpress stores data base64 encoded in the database. Meaning you can't just do a search replace when you migrate a site to a different domain. That combined with Chrome based browsers not loading mixed security assets, but Firefox (the browser I use) does, makes for a confusing trouble ticket.
You have to change the setting to serialize sanely, then go into every post and save to update the stored data. Fortunately, the site is new so I only had one page to update, but I can't imagine the headache an established site would be to migrate.3 -
So I have a question to anyone familiar with the General Transit Feed Specification...
Why is the data provided in text files? Is there not a way to format the data to allow for random access to it?
Like I'm currently writing a transit app for a school project, and as far as I can tell, the only way to get all specific stops for a route, is to first look up all trips in a route, then look up all the stopids that are associated with a trip in stoptimes.txt (while also filtering out duplicates since the goal is to get stop ids, not specifically stop times) and then look up those stop ids in the stops.txt file.
The stoptimes file alone is over 500000 lines long, unless there is a way better way to be parsing the data that I'm not aware of? Currently I'm just loading the entire stoptimes file into a data structure in memory because the extra bit of ram used seems negligible compared to the load times I'm saving...
Would it be faster if I just parsed all the data once and threw it into a database? (And then updated the database once a month when the new data comes in?)3 -
Told the 3rd party developer we wanted a feature in the software they are developing. When you change the master data X we want the corresponding historical Y's to be updated.

Growing list of asks to a team member that are unheeded:
1) Check in your code frequently
2) Stop the completion emails for your program
3) Stop using your personal UserID/Password to send said email
4) Create classes that do one thing
5) Reuse your database connections
6) Use DataTables and write to the database once and not a bunch of variables and write at the end of your crazy loop-if-else structures. -
Question:
For a real time chat (web) app. Whats the best technology to use for this? I dont want the chats to have delays or glitches (in case it gets sent but not delivered etc).
Backend stack is java spring boot
How about kafka? Or rabbitmq? Or socket.io? Should i use redis? Should i use AWS SQS? Talking about cloud what AWS tools should i be using to handle this the best way?
Note: it must be scalable. Meaning if i wanted to extend this software more by building a mobile app (aside from web), i should be able to use the same backend easily
Note 2: it is not ONLY a chat app. Chatting is just 1 out of many functionalities. So chatting is not the main component of the project just a side thing
Keep in mind the backend is a microservice architecture etc. Database postgresql.14 -

Need some assistance with Drupal and Dreamfactory.
Dreamfactory is an amazing piece of software that basically turns any database into a REST API. I mean any DB from SQL Server to MySQL and all kinds of others. For a connection to the API it uses JWT (JSON Web Tokens) which expire momentarily.
On Drupal, there's wsdata and rest client modules. Restclient is a module where you configure a connection via OAuth or HybridAuth to a rest server. The problem is that the rest server for dreamfactory uses JWT and i'm not sure how to get Drupal and restclient to connect that way. -
Last Saturday, I came across a fellow techie at a house party. As soon as he found out I am a developer, the question
"What is your favorite programming language?"
came bursting not even a nano-second after I told him.
Anyone else finds this super cringe?
I believe that people who dig deep trenches in such a topic will be the root cause for the next software crisis. I mean, look at Javascript. In one of my later posts, literally noone could give me a reason to not think Javascript is a dumpster fire. And yet it spread out like a malignant tumor.
To verify not all is lost, I quickly googled any databases written in JS, and luckily just found one archived repo and nothing else. Because Im calling it, once Javascript reaches the database layer, it's terminal.4 -

I wanted to know what is the worst mistake you make on database.
I have actually implements the logic of token access control on database and not on business logic layer.
The database have a login procedure which accept username and password. That login procedure actually hash the password and try to authenticate user.
If it is a correct user , it generate a token. In other to use other procedure on database , you must provide a token. By using that token , the procedure know who is it and what permission is granted to that user.4 -

What dev thought this would be a good idea in Swift? Sometimes I hear the compiler's thoughts as it comes across this:

A friend of mine just asked me if I can make an ERP System for his father, he wants to take control of the inventory, and the merchandise decrease.
Any advice of which database would be better for this job since I don't think he is going to pay for a license or something like that.
I was thinking using MySQL and C# or maybe Java.
Any comment is well appreciated ☺️7 -
BEHOLD! The voting power of Bill Gates!
j/k just a "bug" in my app, the rants were loaded this morning but going thru them now and upvoting.
But that gives me an idea for another app or maybe @dfox can just generate it from the database (not sure if he'd like me spamming the server to monitor the scores on certain rants).: A time graph of how a rant's score increases. -
Fuck you, webdev.
I had to explain to a new web developer about an Oracle database and Toad. Anyone remember Toad? I still remember not too long ago, developers knew the basics of relational databases and available client tools. -
I'm currently starting to develop a simple web app to access a database, just simple read, write, update stuff. Doesn't need to be fancy or anything, just work.
Now I asked a PHP dev I know for help and he told me I should use Symfony and Easy Admin Bundle. I'm not sure rn if it'd be worth it to get to know how to work with frameworks or not. What do you guys think?
Btw, I'm not planning on doing a lot more web development.3 -
My most hated term BY FAR is "In theory". It's a lousy-ass, weak excuse for not doing shit properly while distancing yourself from the problem. Short guide: "in theory" may be used prior to or following a statement in which you have little or no confidence in.
The web server shouldn't reach the database server "in theory", it fucking does or doesn't. The SQL cluster shouldn't "in theory" fail over to a working server in case of a hardware fault. Fuck off with your irresponsibility, man up and do things properly. This is the real world, not a sandbox for your shitty dorm room code1 -
So I´m still working on that Sync to get rid of this abomination called Wrike.
Now I have a problem.
To be able to sync mantis with our software I need to be able to create projects in mantis through the API.
No problem.
But then again, I need to link custom fields to that just created project.
The mantis API apparently doesn´t have that.
I now have two options:
1. I expose the custom field functions myself on the REST api.
2. I gain direct access to the mysql database and do it within my sync job in the database.
Well I´m not a web developer. Like, at all.
But I thought: Hey how hard can it be?
So I got an Apache server with php, mysql and XDebug running with VSCode.
Works better than expected.
But now that I have actually seen the mantis code, I´m seriously considering number 2 again...
Fucking php... -
Y'know, there are some things that are timeless. Like bug severity arguments. We don't have a "likeliness of occurrence" parameter in the bug database. We just have "severity if it occurs". You have to classify it as such. The bug database IS NOT FOR RISK MITIGATION ACTIVITIES IT'S FOR FIXING THE FUCKING SOFTWARE!!! STOP MAKING THESE DAMN MEETINGS TAKE 30 YEARS BY QUESTIONING THE SYSTEM THAT WAS ESTABLISHED IN THE BEFORE TIMES BY PEOPLE WHO ARE ABOVE YOUR PAY GRADE!!! TINDER BOX!!! MATCH!!! GODS DAMMIT!!!

One of my Computer Science modules this year revolved around completing a team project, and one person in the team basically fucked it up for all of us in the last minute.
We had to create a simple task management app for a fictional company, the university did not care about how the program looked and all that mattered was if the app is functional or not. The app relied heavily on a database, so all we basically had to do was get, modify, and add data from a database. Now this person did his part of the programming, but with an outdated database model and did not even test his code as he said MySQL wasn't working on his home computer.
2 days before the final deadline is when we decided to merge everything together in the git repo (as that's when the rest of us finished our tasks), and that's when we found out none of his code worked. We then spent the next 48 hours with little sleep to try our best to fix everything, but unfortunately due to his tasks carrying a majority of the complexity of the program we couldn't fix it all in time and we ended up losing roughly 50% of the marks.
This all probably could have been avoided if one person in the team did look at his git branch properly, but this person was the programming lead of the project and didn't ask for any help at any point until the last moment when we merged everything together. Oh well though, at least I've learnt better for the next team project that I do2 -
Anyone familiar with Wordpress site migration?
I'm trying to move a client site from my dev server to theirs, seem to do so fine, but all urls still point to my dev domain.
A search and replace plugin was recommended but it doesn't seem to be updating the database references correctly...or at all.
Not sure if anyone would mind lending some insight so I don't have to essentially redo the whole website over :p8 -
Imagine working hard on a project, bought a lot about database yourself and other expansive stuff, not sleep for several nights, and every users congrats only the project manager who just ask you once per week if the project is done... just imagine how terrible is your life...3

The job description of my internship:
You must be able to understand the complexities of receiving a unit test that you are told needs only mock data in the test database, but has never worked since it was written by a contractor a year ago. No one knows how the unit test works and requires testing a complex algorithm involving graph theory that you have not learned about yet. The task starts at 1 complexity and turns into a 13. -
So at the end of our sprint retrospective we (me and one other dev) apologize to the project owner for the fact that QA had to happen on dev for a few days because the database changes were not properly applied by the DBA. It was a one time thing, a little weird but not a big deal.
A few hours later we get a call from a new DBA saying that the project owner said that we wanted the old DBA off our project. So now we sound like assholes ruining a guy's self confidence and made working with him awkward as hell.
Thanks, project owner. -
Soooooo, how often does it happen that someone nukes a database and attempts for a restore fail?
Asking for a friend, who happens to be "future me"
Iam very much not responsible for fixing it but I will have a whole lot of work....7 -
Today I was fighting a bug in php that resulted in a steady increase of the upload time of a picture. I printed it out together with some other like the amount of accesses on the image.
They where separated with <br> tags which were not displayed for some reason (maybe you already gueesed it here).
I ask my teacher to help me out, because the entry in my database was correct, the value I received was correct, but not the displayed value...
We even modified the database structure in order to find the bug, but it turns out the error was how I displayed the values. TIL that strings are not concatenated with a '+', but with a '.', the hard way.
Next problem: why is the access count incremented? Also why 3 times?😅 -
Not a rant more like a question
Hello devRant,
I am currently planning to purchase a small home server + media client (with Kodi).
A small Linux Distro running the Hometheateroftware Kodi will run on the media clients (Odroid C2). The control is then over an app over the local network. The database of Kodi should be on the server in the form of a MySQL database. The movies, pictures, music are also streamed by the server (max. 2 simultaneously) via SMB (simplest variant). In addition, the server is to be accessible to the outside via a web interface to act as a cloud (maybe nextcloud). The whole should be optimized for stability and longevity. In addition, a small GitLab CE instance will probably run on the server. Do you have any comments or objections? The fact that I only take 2x ne 2 TB hard drive has the simple reason that I currently have no need for more space. Sometimes it happens to me that I forget completely obvious things :D -
I wonder if there is any technical issues that prohibit the creation of open source websites.
By "web sites" I do not consider CMS like Drupal or word press, but rather entire end web site sources.
In fact anything (frontend, backend) except database content that contain user data and credentials.
Not for reusability purposes like CMSs, but simply for transparency and community development purposes, like almost any open source end application.
I agree that a web server is much more exposed than a classic desktop app, as it has lots of targetable private data and internet public access. But for some non-critical purpose this seems to be affordable in exchange of better code review, allowing a community to help improve a tool it uses, and better (not perfect though) transparency (which is an increasingly relevant question nowadays, mainly towards personal data usage).6 -
I spent the whole weekend trying to get some messages of a database on Android, getting a lot of ANR (Application Not Responding).
I just found the problem. The database was damaged.
I've lost one weekend.1 -
Only last month I removed a file called 'statuspage.aspx', this file has been sat there for years on our customer sites.
The file did one simple query on the database to ensure connectivity, this query dumped the admin username and password to the page, no encryption.
Needless to say we rolled out ab emergency update... Not quite sure how that made it through QA! -
Today a collegue ranted about that he needs 96 variables in his code and also for the database querys and told me that's not possible to do it without so many variables... I just thought wtf.. I definitely need a new job!
-
Spent a good hour trying to query for data in DEV. I was seeing the data on the page but not getting any results back time after time, checked everything.
Looked closer and found out I was querying the QA database... 😤😧 -
"This module wraps around this genuinely awesome database and provides all the in-memory storing of the database so that nothing is persisted"
nice, just like I need it
Hudden truth:
"but in order to make it non-persistent you have to clear the database on every startup"
This shit cost me so much fucking time time, works needs it's sucked for every transaction, just for basic features not being implemented and performing even worse than standard choices because you can't leverage it's power for shit?
Fucking waste of time. I could have finished the Api with the standart module a long time ago, but I'm such and idiot and want to step outside my comfortzone too much.
I'm switxhing the fuxk back and maybe I get this done within 3 hours1 -
Best eays to improve database performance?
I have a huge database table with a lot of data, 10+columns and around 5-6million rows and growing. We are thinking about optimisation methods, the data will be frequently accessed, but not in the same ways. even though caching is helping, some initial requests take 6-20secs. What are good ways to improve a relational db performance? The data is date and item based, every item can have some data back from 2016 or older and up to 1000 related rows in each day. Every day new data would be added. Right now working with php.8 -
So I have spent the entire morning trying to fix null values in the database, because they keep fucking up my code.
I hate the fucking person who made the database at the place I work, dude has not heard of a thing called NOT NULL!!! -
The highlighted lines are a part of a flask app I'm writing in Python2(not python3 because I'm a bit too lazy to fix few dependency errors). All functions work as expected and all templates are rendered individually, and routes are all defined. check_date checks for invalid dates like 32Jan, 2018. It returns 0 if date is valid. add_data basically returns 0 if it decides to add user data into the database(db).
The problem is that line 60 renders but lines 54,57 don't. Any ideas as to what might be going wrong.?
PS: I'm building this app for learning and not for a production environment...1 -
I'm not sure who the fuck implemented the error handling of spring boot but goddamn he/she needs to be fired. Why the fuck does the application return a weird error about a setting not being set when it can't connect to a database?? Wtf took an hour to solve and that's not the only thing I hate about spring boot. Why is the documention utter garbage, why do I have to rely on tutorials and can't I just read in the documentation how for example the http rest mapping works. Now I have to cross-reference multiple tutorials to find the best way because guess what there are multiple ways to do something in this framework and some tutorials don't even work.
-
I can't stand when people spend a single day familiarizing themselves with a new technology or concept and then come to the conclusion that's it doesn't work and really the old way is great. Not saying all new things are better. In fact, I'm probably more in favor of tried and true methods than shiny new methods. But one day? Really? That's all it took? In this particular case it's code-first DB development. Again, I'm not a fan myself really. But I have a co-worker who said creating tables and and schemas is much harder using code-first instead of DB first. I mean... Neither are hard. I personally think it's easier for basic things like tables and schemas but either way it's not hard. Now SQL triggers and index's all that fun stuff? Yeah code first is probably more complicated (I'm clearly not a database expert or anything). But a day? Really? You know enough to force a design paradigm on the whole company now? Wtf.3

Why is customer support sometimes so shitty? A coworker good a Win10 Laptop (Win7 before) and one program wasn;t working there anymore. So we reached out to the support asking to help us fix it. After over a month later and x-amount of E-mails back and forth. The answer was, you have to upgrade everything (Webserver, Database, Client) to use Win10 (no backwards compatibility). Which is fine, I don't mind upgrading and understand that software sometimes is not backwards compatible. BUT THAT IS SOMETHIGN TO STATE IN THE 2nd E-MAIL. Not an infinity later after a tiring back and forth of nonsense.

You just have to love users, especially when you work in an environment where politics dictate database constraints and application rules.
"Can you pull tax info for x, y, and z."
Nope, I could if the stuff was entered into the database properly but until standardized I can't do much. Here are the numbers I have, use them or don't but I'm not fabricating data for you for a tax form. -
Three possible strategies for adding a new feature. Not sure which is the best, so I'm going to go with the one that's least invasive to the existing structure of the database.3
-
No, why would you make sure your not working with a database over a year old. Totally our fault, we're jackasses for telling you to do it over again.

Following some new nextjs tutorial to learn how to efficiently build a web chat app, the guy built it very solid, but is it efficient?
Im having mixed feelings about this approach. The way he did it is, for example when you click on a user (imagine it as a list of users from your contacts), it actually calls a route, which stores that in database, and once its done Then the route triggers lets say socket.io event to notify the frontend to update the UI.
Not only that but each new message that gets sent it actually calls a route which stores that message in database and once that's successful Then it emits a socket.io event to the frontend to fetch that message.
As you can imagine constantly calling routes like this Does induce small delays. Creating conversations, navigating, opening someones profile and especially sending messages, is NOT instantaneous. When you do it theres a small delay, giving the impression as if the app is SO large that it lags
But it doesnt lag, it just needs a few ms to store that in db so it can return the socket.io bidirectional message event. Which does make sense because what if the internet broke and the user immediately gets sent a message, but the message fails to get stored in database? Or db storage gets fucked or something else fails but socket.io works while db doesnt? The data then may be inconsistent. This approach fulfulls the single source of truth principle
So thats why im having mixed feelings about this approach particularly because of small delays. It is not instantaneous like whatsapp discord telegram signal viber etc the input UI freezes until the message is successfully sent
---
Of course this can be a UI/UX decision and can be handled differently even if the backend works like that.
My concern is is this approach valid?
My question is... I had an idea what if i emit socket.io event to send the message while in the background also call the route to store that message in db? This way not only would it work asynchronously but the message gets sent instantaneously, and if the backend fucks up to store it in db then the UI gets updated with message failed to get delivered, switching the socket.io into polling state. Is this a good (proper, efficient, better) way to do it or not?8 -
A question guys, I'm looking for a DB client. We are using SQL Management Server Studio, but its way way overkill for a frontend guy like me.
Min Requirements:
- Needs to be simple
- Must support MSSQL
- Plugin support and/or dark mode
- Free and/or not too buggy evaluation (like Sublime or Winrar)
- GUI should be reasonably modern
- Should also be native. Our database is a denormalized mess.6 -
Does anyone know a good method, or library to match 2 gps locations based on proximity to each-other?
while being fed a few 100 GPS locations per device per hour.
I currently do it by having the client send their Geohash to a database, then request all neighboring hashes around it and all other clients in those hashes, then get their GPS to check for distance.
But this does not seem to work flawlessly, it works on tests and emulators (its for phones) but on real phones it seems to be hit an miss, but no errors, the event just does not seem to fire.4 -
Okay so Ive been working on a custom queueing system
basically the system generates ticket numbers for checked in paients and then assigne them to a room when it's their turn to be attended to
so I'm having some challanges with the database when the patient finishes their session with the Dr the admin can remove them from the queue and is supposed to reset the room.state = 0 //which means room in unoccupied
this is proving to be problematic coz it's not even finding the room

Okay soo I’m not a database guy.. I’m an embedded engineer but I’m helping one of my interns make a hardware tracking database... so we are tracking assembled products (dev samples).. but also tracking the pcbs within the product.. depending on the product it might have more than one pcb or contain other components to track.
The question is how would I set up the relationship in the tables, so depending on the say “type id” of the product it would link to a table full of feilds specfic to that “type”.. say the product is of type phone and has a pcb of this and a camera of that.. blah blah blah.... but say another product is of type “washing machine”.. which has no screen, it has a different pcb, but also has other things..
There would be a type table .. washing machine, phone, tv, camera, pcb, ecu.. etc.. but those type would need their own tables...
I guess the question is how to relate a field to different tables depending on the value of the field... is this portion all done thru query results and logic rather than pure data base schemas?
What would be the question in terms of database lingo to google search the answer lol2 -

Hi, guys. I'm looking to get into Android development (Xamarin) and to build some simple apps first.
What I have in mind is something trivia-like, with a hosted database (can't find any free & reliable public APIs).
Do you know of any free downloadable databases on the topics of:
- trivia
- humour
- entertainment
http://www.usabledatabases.com/ seemed promising, but it's not free (or I couldn't find any free DBs, as they don't have a price filter).
Thanks in advance! -
We are migrating database from A to B. I am developing software for B side.
I am glad that there is only one B database instance. More excuses for long breaks when it is down for creation from start that takes 30 min.
I requested a database B copy for development purposes. Company is not that “agile” for such things. There is no feeling of guilt on my side.2 -
I am using MERN to develop a poll app. I have 6 collections in my database. I have an API for each collection, 4 of those API returns the data whereas the other 2 return 'undefined'. What is the issue I am facing? Is MongoDB not allowing me to use more than 4 collections?6

I was working on a project a while back making a language system, we obviously wanted to know what language the user had set so I looked to adding it to the database.
I've seen messy code and I'm not a gold standard but fml..
I ask the other dev who wrote the code and we end up spending a while getting it sorted. I had never seen the database before... 100+ fields on the main table...
I quit not long after. Hated that job and I have many things I can rant about from it. -
So finished 2 weeks project for co-worker. Now she can register cargo waybills to database and not to excel(I have nothing against it, but to have centralised way to keep data is better practice). Anyway project was done with Cpp, wxwidgets(first time trying GUI in my project), postgressql. Now I can see a lot of things I can rework, fix or add something new. I guess you can't finish fully anything.

Hey database experts. MySql question:
I have a table with houses, there is the location, color, etc. Shall I make a column for the owner or make a separate table HouseToOwner - where I connect the id's? I have no idea why is it good practice but saw it in few cases. I have the same with the things inside like I would just make a boolean column for a TV-like haveTV - true/false. Tell me why to not fill everything in one table. thx17 -
Function in my Dao file is:
@Query("SELECT * from appData WHERE type = :type ORDER BY id DESC")
fun getData(type: String): Flow<List<AppData>>
The database contains a column of automatically generated int primary key 'id', a column of string named 'type', and another string column named 'content'.
A Part of code from my composable function is:
val currentRetrievedDate: Date = Date()
val currentDate: String = SimpleDateFormat("dd-MM-yyyy").format(currentRetrievedDate)
var lastDateObjectList by remember { mutableStateOf(emptyList<AppData>()) }
LaunchedEffect(streakCounterViewModel) {
coroutineScope {
streakCounterViewModel.appDataRepository.getDataStream("lastDate")
.collect { newDataList ->
lastDateObjectList = newDataList as List<AppData>
}
}
}
if (lastDateObjectList.size>1){/*TODO*/
for (i in 1 until lastDateObjectList.size){
LaunchedEffect (Unit){
streakCounterViewModel.deleteData(id = lastDateObjectList[i]!!.id,
type = lastDateObjectList[i]!!.type,
content = lastDateObjectList[i]!!.content)
}
}
}
val lastDateObject: AppData?/* = lastDateObjectList[0] ?: null*/
lastDateObject = if (lastDateObjectList.isNotEmpty())
lastDateObjectList[0]
else null
var lastDate = lastDateObject?.content ?: "00-00-0000"
var currentStreakObjectList by remember { mutableStateOf(emptyList<AppData>()) }
LaunchedEffect(streakCounterViewModel) {
coroutineScope {
streakCounterViewModel.appDataRepository.getDataStream("currentStreak")
.collect { newDataList ->
currentStreakObjectList = newDataList as List<AppData>
}
}
}
if (currentStreakObjectList.size>1){
for (i in 1 until currentStreakObjectList.size){
LaunchedEffect (Unit){
streakCounterViewModel.deleteData(id = currentStreakObjectList[i]!!.id,
type = currentStreakObjectList[i]!!.type,
content = currentStreakObjectList[i]!!.content)
}
}
}
val currentStreakObject: AppData?/* = currentStreakObjectList[0] ?: null*/
currentStreakObject = if (currentStreakObjectList.isNotEmpty())
currentStreakObjectList[0]
else null
var currentStreak = currentStreakObject?.content ?: "0"
In this code, the last login time and last streak of user is already saved, we just have to fetch the data from the local database, make sure that there are not more than 1 occurrences of same data type in the database, and then use that data. But this, instead of using the database values, uses 00-00-0000 as the lastDate, and uses "0" as the currentStreak (which should only be used for the first not, and in some rare situations only), and is not able to retrieve data from the database properly.
The data saving and updating logic is working fine, but only the retrieval part is causing some issue.
The complete project is also uploaded on github: at HealthEase repo of tauqirnizami4 -
Why is my Spark Dataframe getting written as empty in the database table when deleting records? There’s no problem when inserting records, and I I have verified that my Spark Dataframe is not empty when trying to rewrite using Overwrite method. Then why is my whole table data getting deleted when I’m just trying to remove a few records using left_anti join?1

So... I've been thinking, I tend to default to LVM when trying to create easy-to-manage disk partitions, or when I want to backup a database without long lockings during a dump... Though, now... I got thinking.
What do you guys think, which is better in terms of functionality: BtrFS or LVM?
I know BtrFS offers such thing like full snapshots that allow to easily transfer just the increment over the snapshot origin off to a remote server for archival, but I never fully grew to trust btrfs as a server filesystem... Its...
Younger, and not as widespread, not to mention I don't know any performance statistics to recommend its use for this or that case (Like... Would a high-load database engine stutter flushing all those changes on disk while reading / writing temp tables and such)6 -

I am currently trying to set up a unit-test using Python Django framework.
I follow the official documentation step by step. I completed the steps.
It spits out an error: the table does not exist in the database.
Seriously, do you need any more proof that Python is bad? The developers of Python framework cannot even put together a working tutorial. If the unit-test framework requires the database then it should auto-create the tables3
