Good Morning!, its time for practiseSafeHex's most incompetent co-worker!
Todays contestant is a very special one.
*sitcom audience: WHY?*
Glad you asked, you see if you were to look at his linkedin profile, you would see a job title unlike any you've seen before.
*sitcom audience oooooooohhhhhh*
were not talking software developer, engineer, tech lead, designer, CTO, CEO or anything like that, No No our new entrant "G" surpasses all of those with the title ..... "Software extraordinaire".
*sitcom audience laughs hysterically*
I KNOW!, wtf does that even mean! as a previous dev-ranter pointed out does this mean he IS quality code? I'd say he's more like a trash can ... where his code belongs
*ba dum tsssss*
Ok ok, lets get on with the show, heres some reasons why "G" is on the show:
One of G's tasks was to build an analytics gathering library for iOS, similar to google analytics where you track pages and events (we couldn't use google's). G was SO good at this job he implemented 2 features we didn't even ask for:
- If the library was unable to load its config file (for any reason) it would throw an uncatchable system integrity error, crashing the app.
- If anything was passed into any of the functions that wasn't expected (null, empty array etc.) it would crash the app as it was "more efficient" to not do any sanity checks inside the library.
This caused a lot of issues as some of the data needed to come from the clients server. The day we launched the app, within the first 3 hours we had over 40k crash logs and a VERY angry client.
Now, what makes this story important is not the bugs themselves, come on how many times have we all done something stupid? No the issue here was G defended all of this as the right thing to do!
.. and no he wasn't stoned or drunk!
G claimed if he couldn't get the right settings / params he wouldn't be able to track the event and then our CEO wouldn't have our usage data. To which I replied:
"So your solution was to not give the client an app instead? ... which also doesn't give the CEO his data".
He got very angry and asked me "what would you do then?". I offered a solution something like why not have a default tag for "error" or "unknown" where if theres an issue, we send up whatever we have, plus the file name and store it somewhere else. I was told I was being ridiculous as it wasn't built to track anything like that and that would never work ... his solution? ... pull the library out of the app and forget it.
... once again giving everyone no data.
G later moved onto another cross-platform style project. Backend team were particularly unhappy as they got no spec of what needed to be done. All they knew was it was a single endpoint dealing with very complex model. There was no Java classes, super classes, abstract classes or even interfaces, just this huge chunk of mocked data. So myself and the lead sat down with him, and asked where the interfaces for the backend where, or designs / architecture for them etc.
His response, to this day frightens me ... not makes me angry, not bewilders me ... scares the living shit out of me that people like this exist in the world and have successful careers.
G: "hhhmmm, I know how to build an interface, but i've never understood them ... Like lets say I have an interface, what now? how does that help me in any way? I can't physically use it, does it not just use up time building it for no reason?"
us: "... ... how are the backend team suppose to understand the model, its types, integrate it into the other systems?"
G: "Can I not just tell them and they can write it down?"
**
I'll just pause here for a moment, as you'll likely need to read that again out of sheer disbelief
**
I've never seen someone die inside the way the lead did. He started a syllable and his face just dropped, eyes glazed over and he instantly lost all the will to live. He replied:
" wel ............... it doesn't matter ... its not important ... I have to go, good luck with the project"
*killed the screen share and left the room*
now I know you are all dying in suspense to know what happened to that project, I can drop the shocking bombshell that it was in fact cancelled. Thankfully only ~350 man hours were spent on it
... yep, not a typo.
G's crowning achievement however will go down in history. VERY long story short, backend got deployed to the server and EVERYTHING broke. Lead investigated, found mistakes and config issues on every second line, load balancer wasn't even starting up. When asked had this been tested before it was deployed:
G: "Yeah I tested it on my machine, it worked fine"
lead: "... and on the server?"
G: "no, my machine will do the same thing"
lead: "do you have a load balancer and multiple VM's?"
G: "no, but Java is Java"
... and with that its time to end todays episode. Will G be our most incompetent? ... maybe.

Android Development be like:
- Has great idea for app or feature
- Boots up PC
- Starts android studio and creates new project
- Build error
- Gradle build failed
- Android studio crashes
- Java Error
- Shutsdown PC
- Goes and hangs himself
Pretty accurate if you ask me 😀😀😀😎18 -
Was going through some old gadgets n found this fossil.

LONG RANT AHEAD!
In my workplace (dev company) I am the only dev using Linux on my workstation. I joined project XX, a senior dev onboarded me. Downloaded the code, built the source, launched the app,.. BAM - an exception in catalina.out. ORM framework failed to map something.
mvn clean && mvn install
same thing happens again. I address this incident to sr dev and response is "well.... it works on my machine and has worked for all other devs. It must be your environment issue. Prolly linux is to blame?" So I spend another hour trying to dig up the bug. Narrowed it down to a single datamodel with ORM mapping annotation looking somewhat off. Fixed it.
mvn clean && mvn install
the app now works perfectly. Apparently this bug has been in the codebase for years and Windows used to mask it somehow w/o throwing an exception. God knows what undefined behaviour was happening in the background...
Months fly by and I'm invited to join another project. Sounds really cool! I get accesses, checkout the code, build it (after crossing the hell of VPNs on Linux). Run component 1/4 -- all goocy. run component 2,3/4 -- looks perfect. Run component 4/4 -- BAM: LinkageError. Turns out there is something wrong with OSGi dependencies as ClassLoader attempts to load the same class twice, from 2 different sources. Coworkers with Windows and MACs have never seen this kind of exception and lead dev replies with "I think you should use a normal environment for work rather than playing with your Linux". Wtf... It's java. Every env is "normal env" for JVM! I do some digging. One day passes by.. second one.. third.. the weekend.. The next Friday comes and I still haven't succeeded to launch component #4. Eventually I give up (since I cannot charge a client for a week I spent trying to set up my env) and walk away from that project. Ever since this LinkageError was always in my mind, for some reason I could not let it go. It was driving me CRAZY! So half a year passes by and one of the project devs gets a new MB pro. 2 days later I get a PM: "umm.. were you the one who used to get LinkageError while starting component #4 up?". You guys have NO IDEA how happy his message made me. I mean... I was frickin HIGH: all smiling, singing, even dancing behind my desk!! Apparently the guy had the same problem I did. Except he was familiar with the project quite well. It took 3 more days for him to figure out what was wrong and fix it. And it indeed was an error in the project -- not my "abnormal Linux env"! And again for some hell knows what reason Windows was masking a mistake in the codebase and not popping an error where it must have popped. Linux on the other hand found the error and crashed the app immediatelly so the product would not be shipped with God knows what bugs...
I do not mean to bring up a flame war or smth, but It's obvious I've kind of saved 2 projects from "undefined magical behaviour" by just using Linux. I guess what I really wanted to say is that no matter how good dev you are, whether you are a sr, lead or chief dev, if your coworker (let it be another sr or a jr dev) says he gets an error and YOU cannot figure out what the heck is wrong, you should not blame the dev or an environment w/o knowing it for a fact. If something is not working - figure out the WHATs and WHYs first. Analyze, compare data to other envs,... Not only you will help a new guy to join your team but also you'll learn something new. And in some cases something crucial, e.g. a serious messup in the codebase.11 -
Its that time of the morning again where I get nothing done and moan about the past ... thats right its practiseSafeHex's most incompetent co-worker!!!
Today I'd like to tell you the story of "i". Interesting about "I" is that he was actually a colleague of yesterdays nominee "G" (and was present at the "java interface" video call, and agreed with G!): https://devrant.com/rants/1152317/...
"I" was the spearhead of a project to end all projects in that company. It was suppose to be a cross-platform thing but ended up only working for iOS. It was actually quite similar to this: https://jasonette.com/ (so similar i'm convinced G / I were part of this but I can't find their github ID's in it).
To briefly explain the above + what they built ... this is the worst piece of shit you can imagine ... and thats a pretty strong statement looking back at the rest of this series so far!
"I" thought this would solve all of our problems of having to build similar-ish apps for multiple customers by letting us re-use more code / UI across apps. His main solution, was every developers favourite part of writing code. I mean how often do you sit back and say:
"God damn I wish more of this development revolved around passing strings back and forth. Screw autocomplete, enums and typed classes / variables, I want more code / variables inside strings in this library!"
Yes thats right, the main part of this bullshittery was putting your entire app, into JSON, into a string and downloading it over http ... what could possibly go wrong!
Some of my issues were:
- Everything was a string, meaning we had no autocomplete. Every type and property had to be remembered and spelled perfectly.
- Everything was a string so we had no way to cmd + click / ctrl + click something to see somethings definition.
- Everything was a string so any business logic methods had to be remembered, all possible overloaded versions, no hints at param types no nothing.
- There was no specific tooling for any of this, it was literally open up xcode, create a json file and start writing strings.
- We couldn't use any of the native UI builders ... cause strings!
- We couldn't use any of the native UI layout constructs and we had to use these god awful custom layout managers, with a weird CSS feel to them.
What angered me a lot was their insistence that "You can download a new app over http and it will update instantly" ... except you can't because you can't download new business logic only UI. So its a new app, but must do 100% exactly the same thing as before.
His other achievements include:
- Deciding he didn't like apple's viewController and navigationBar classes and built his own, which was great when iOS 7 was released (changed the UI to allow drawing under the status bar) and we had no access to any of apples new code or methods, meaning everything had to be re-built from scratch.
- On my first week, my manager noticed he fucked up the login error handling on the app I was taking over. He noticed this as I was about to leave for the evening. I stayed so we could call him (he was in an earlier timezone). Rather than deal with his fucked up, he convinced the manager it would be a "great learning experience" for me to do it ... and stay in late ... while he goes home early.
- He once argued with me in front of the CEO, that his frankenstein cross-platform stuff was the right choice and that my way of using apples storyboards (and well thought out code) wasn't appropriate. So I challenged him to prove it, we got 2 clients who needed similar apps, we each did it our own way. He went 8 man weeks over, I came in 2 days under and his got slated in the app store for poor performance / issues. #result.
But rather than let it die he practically sucked off the CEO to let him improve the cross platform tooling instead.
... in that office you couldn't swing a cat without hitting a retard.
Having had to spend a lot more time working with him and more closely than most of the other nominees, at a minimum "I" is on the top of my list for needing a good punch in the face. Not for being an idiot (which he is), not for ruining so much (which he did), but for just being such an arrogant bastard about it all, despite constant failure.
Will "I" make it to most incompetent? Theres some pretty stiff competition so far

We were all 16 once right? When I was 16, my school had a network of Windows 2000 machines. Since I was learning java at the time, I thought learning batch scripting would be fun.
One day I wrote a script that froze input from the mouse and displayed a pop up with a scary “Critical System Error: please correct before data deletion!!”. It also displayed a five minute countdown timer, after which the computer restarted.
I may or may not have replaced the internet explorer icon on the desktop with a link to my program on the entire student lab of computers. Chaos.12 -
Okay i'm done - YOU FUCKING ANDROID STUDIO MORONS. Being at a high level in C++, I tried to do some android coding. THERE ARE FUCKING NO GOOD TUTORIALS, NO GOOD DOCS, HECK, THE SELF GENERATED CODE OF THE IDE IS WRONG: WHAT THE FUCK IS GOING ON YOU FUCKING MORONS?
oh wait, let me first import android.widgets.rant;
or was it android.widgets.devrant.rant; or was it android.dr.rant.RantManager;?
Oh wait, I know lets search the docs?
OH WAIT THE DOCUMENTATION DOESNT HAVE THAT.
NOW HOW ABOUT I JUST TRY THE EXAMPLE CODE? WELL UH-UH! YOU HAVE TO FIND OUT YOURSELF WHAT TO IMPORT IN ORDER FOR IT TO WORK. ALSO, WHAT FUCKING UP WITH THAT PERMISSION SYSTEM? ITS SO BADLY DOCUMENTED!!!
Oh wait, I'm sure that I have to change something in this file... or was it that other file?
GOD
how dare they have style and design guidelines?
MORONS!
I will resort to implement my app idea in godot, idc anymore... I don't want to burn out because I used the "official high standard" tech.
it definitely isn't high standard and definitely not good. Thank you morons@google
THANK YOU FOR NOTHING
A FRAMEWORK WHERE I NEED 2 DAYS TO FIGURE OUT TO ADD EVENT LISTENERS TO MY THINGS IS DEFINITELY NOT ONE I'D LIKE TO USE.
also, whats up with
AudioRecord (int audioSource, int samplerateInHz, int channelConfig, int audioFormat, int bufferSizeInBytes);
ARE WE BACK IN THE C ERA? CAN'T YOU BE BOTHERED TO IMPLEMENT SOME SIMPLE FUCKING ENUMS????
WHATS THE POINT OF AN OOP LANGUAGE IF YOU ARE GOING TO USE IT LIKE C?
Oh wait I found a tutorial ... First trigger: "java scripts". Second trigger: this guy LITTERALLY ONLY TEACHES YOU HOW TO PLACE WIDGETS ON THE CANVAS. THANKS FOR NOTHING SHERLOCK!
Oh btw: did you know that android studio gives the best error messages?
"Error: illegal start of expression"
NO ERROR MESSAGE - NOTHING!
YOU BETTER USE THE IDE OR YOU GO HOME YOU FUCKER!!!
Oh and btw: if you want to read the best documentation - the code itself YOU GOTTA AGREE TO OR TERMS OF SERVICE!!!! WE DONT WANT ANYBODY TO BECOME SUCCESSFUL WITHOUT US KNOWING!!!!!
THANK YOU GOOGLE FOR NOTHING!
YOU FUCKERS!
thanks godot for *atleast* existing. You are the... last pick i'd pick, but :shrug:, I have experienced android studio now.
If anybody has any advice on what to use instead, please go ahead. And you better not tell me how good you are at android studio. I DONT CARE ABOUT WHAT YOU CAN IMPLEMENT IN ANDROID STUDIO. I JUST WANT SOMETHING THAT IS USABLE WITHOUT HAVING TO BE EXTRA CAREFUL WHEN DOING *ANYTHING*!!!!

My teacher at school who taught me programming. We were taught Java.
You see, Java is not a beginner's language, most say. But the way she taught it, the examples, the analogy, the explanation; she made it so easy.
She made us execute our first Hello World program (using BlueJ) and proudly said, "you're all programmers now!", that was when fascination took me over. I remember that moment till today.
Also, unlike regular exams, the programming exams required extreme competency. Marks were split up for algorithm and syntax. There were also questions like find the error in this algorithm for this output. She would always surprise us at the exams!
I had several glorious moments in class by being the first to answer most of her questions. At 13, it was kind of a big deal for me.
(Okay, who am I kidding, it still is :-P)
*sigh*
It was mostly just self learning from there. I switched schools and then there was college. Attending classes in college was like going to the gym with fat trainers. Utterly useless :-/ It just made me appreciate her even more.5 -
At an interview, the first round was an online coding round. Two questions, one easy one hard, 90 minutes, easy peasy.
I solved the hard one first.
A bit of good logic, followed MVC pattern, all done. Worked flawlessly.
Submitted code. Online compiler threw up an internal error citing java is an invalid command(jdk not found).
Called the invigilators. What I heard next, I couldn't believe this shit.
"We're not responsible for any errors you may be having. Figure it out yourself"
I was like WTF dude. This is not even a compilation or runtime error!
After a heated discussion, I made him look at the code.
Him - what is all this classes and all? Why haven't you written everything inside the main function?
Me - those are model classes. Those are different helper functions. That is a recursive function to avoid 5 for loops and use divide and conquer. Ever heard of OOP? what kind of person writes a 300 line program inside one function?
Him - no no we write it like that only. Correct this.
Me - I fit everything inside the main function. Still the same error, java not installed. Called the idiot to have a look at it.
Him - yeah your code is wrong.
Me - may I know what's wrong with it? Can you fix it please?
Him - no no we aren't allowed to see the code (he had already read it twice. It was compiling and running perfectly, locally) .
Yeah you solved only 1 problem, you were supposed to solve 2.
Me - yes because the rest of the time I had the pleasure of your company. (It isn't everyday that I see talking buffoons.)11 -
Coworker asking for my help on a crm framework I have never seen before. She was banging her head on the monitor by 1 hour. I read the stacktrace of the error (Java), and 30 seconds later I solved her problem.

Spoke to a programmering student who insists on writing his Java and python code in PARAGRAPH format, like an essay (the teachers do not teach this). Tried to explain why this is a bad idea. He explains to me that if others can't read his code that it is their problem and that he would never make a silly syntax error like missing a semicolon or a bracket. Called me stupid and walked off.
Life will be hard for him.10 -

Stack Overflow. Everyone uses it but everyone seems to hate the community. I very often read about someone getting down voted and they all say the same thing - "I have no idea why".
I have spent a lot of time moderating SO posts, which gave me a lot of reputation and medals. I find it fun to help people and it feels good to give back to the community.
I have asked a bunch of questions and I've never gotten a single down vote, which leads me to believe everyone of you that is constantly getting down voted are doing something wrong. Because the posts I see getting down voted are fucking stupid questions that either lack information or contain too much information.
Example 1:
Server java error
Why is my server not working? I am using Tomcat, port 8080 and I'm getting IOException.
Example 2:
Webpack configuration not working
My webpack is not a working, why?
[entire webpack config]
End examples.
What the fuck are you expecting asking questions like these?? No one gets paid for answering your questions, so the least you can do is write a CLEAR AND UNDERSTANDABLE question. I'm not gonna tell you how to do it because there's A LOT of information on how to do it.
People devote hours and hours to helping others on SO, and of course they get fed up with the stupid and lazy questions. That community is not about being nice, it's not about making people feel welcomed, it's about QUALITY OF CONTENT. No one is crying when they find a superb question + answer, right? That's the result of a community not accepting low quality content.
So please, the next time you get a down vote on SO - do not come here whining about it but instead take a look at what you have posted there and ask yourself if it could have held a higher quality.
Thanks!8 -

Teach people how to google properly.
May sound a bit sarcastic but I think an important part is how to look for errors on your own rather than going to the professor/TA. I’ve seen people paste in whole error logs or more often “code throws error, what do?”
At least teach in classes what to look out for like what error type in java and understanding how to look at stackoverflow questions to apply their solution to your issue.
Moral of the story: teach people how to use existing knowledge rather than just depend on someone to help their exact issue.6 -
Went to an introductory session for the new version of the lousy CMS my organization uses and on the second slide of the presentation WRITTEN BY THE BIG BRITCHES OF THE IT DEPARTMENT they informed us that the CMS removes the necessity to learn languages for web programming like HTML, CSS, and Java. My first thought is "huh why would I need Java for... wait..." You could see the thoughts crossing my mind.
"Wait a minute... Who writes Java applets anymore? Java isn't.... but what if... no... they wouldn't..."
For the holy love of Bill, YOU ARE THE IT DEPARTMENT. Please don't tell me you misguided cactus-heads just mixed up JavaScript and Java on an official document you're using in presentations for everyone using the system? It hardly did anything to inspire overwhelming confidence. And even if it was handled by somebody whose entire job is to write PowerPoints for these things, who reviewed this thing? Dilbert's boss? And that wasnt even the only soul-scorching error. Sweet mother of Tux, people, I'm a student using your system, your professional presentations shouldn't make me cringe.3 -

In the begining of time, when The Company was small and The Data could fit in some fucking excel sheets, Those Who Came Before implemented some java tool to issue invoices, notify customers and clear received payments.
Then came the Time Of The Great Expanse, when The Company grew to unthinkable levels. Headcount increased with each passing day, and The Data shows that everything was going great!
But when the future seemed bright, came The Stall-Out. The days when The Company could not expand as fast as it did before. And Those Who Came Before left, abandoning their Undocumented Java Tool to its own luck.
Those who came after knew nothing of the inner workings of the Undocumented Java Tool. They knew only that the magical Jar would take a couple fucking excel spreadsheets and spit out reports and send emails like magic.
And those were The Dark Days.
In the darkness, The Data grew to be a monster. Soon a fucking excel spreadsheet could not hold The Data contained any longer. Those Who Came After, fearing the wrath of The Undocumented Java Tool, dared not mess with its code. Instead, they fucking cut away the lowest volume transactions from the fucking input spreadsheet, and left the company to report the unbilled invoices as "surprise losses". Fucking script kiddies, were Those Who Came After.
Then, at The Darkest of Days (literally, Dec 21st), marched into the project The Six Witchers, who fear not the Demon of Refactoring.
This story is still unfolding. Will The Six Witchers manage to unravel the mysteries of The Undocumented Java Tool? Will they be able to reverse engineer the fucking black box, and scale it's magic into a modern application?
Will they decrease revenue forecasting error by at least 2% in a single strike?
Only the future will tell.16 -
Developer came to our area to rant a bit about a problem he was having with Xamarin. A particular android device was receiving a java runtime error trying to de-serialize data from a WCF contract. What he found was not to use WCF and use WebAPI (or a simple REST service that sent back/forth JSON).
When he proposed changing the service (since the data transport didn’t really matter, he could plug the assembly into a WebAPI project in less than an hour), the dev manager shot down the idea pointing him to our service standard that explicitly stated no WebAPI (it’s in bold letters).
I showed him the date on the “standard”, which was 5 years ago. We have versioning on our sharepoint server, so I also him my proposal notes on the change request document (almost two years before that) stating we should stop using WCF in favor of REST based web standards. Dev manager at the time had wrote in his comment “Will never use REST. Enterprise developers prefer RPC.”
He just about fell over laughing when I showed him this gif.

Java:
Primitive streams. Their need to exist is a monument to legacy failure.
VB.net
OrElse and AndAlso short-circuiting operators. The language designers were too fucking lazy to process logic, so they give specific keywords for those cases.
PHP
Random Hebrew error messages
JS
Eval. It can be used responsibly, but most of the times you see it it's because someone fucked up.
C#
Lack of Tuple destructuring in argument specification. Tuples were added, and pattern matching was added, and it's been getting better. The gear grinding starts with how Tuple identity assignment in arguments is handled. Rather than destructuring into the current scope, it coalesces the identity specification into a dot property of whatever the argument name is. This seems like an afterthought given they have ootb support for ignore characters.
Typescript
This will probably be remedied in the next version or two, but Tuple identity forwarding between anonymous scopes normalizes to arrays of union types, because tuples compile to typeless arrays. It's irritating because you end up having to restate the type metadata in functional series even when there is no possibility for any other code branch to have occurred.12 -
I had a professor in college who was "the expert in java programming language". He had a unique way of teaching.
P: So you save your java file and run this command.
*Some error occurs*
Me: But this is showing some error
P: Exactly. I wanted to show this exact same error so that you learn that this is not how its done. I will let you figure it out how its done and it will be your assignment for the day. Class dismissed.4 -

Cs Student. We currently have a course on algorithms, where we have to implement something in Java, test it with some sample inputs and in the end submit it to an online judge, so far so good. So why a rant? Well there's this one person, who strugles with programing and asks me a lot of questions. Usually I tell her, could you send me your code, so I can have a look at what doesn't work/where you made a typo/what ever. My thoughts: let's just copy it my IDE, take a look at the error message, and that should do it.
Guess how I got the code: As a few photos, taken by her mobile phone (as the code doesn't fit on one screen...)! Just send me the fucking file, or post it to gist.github.com or pastie.org or what ever fucking code sharing tool you want! Make a fucking git repo, I'll even live with SVN or just a .txt file by mail. But for the love of Linus Torvalds, stop sending me crapy pictures of your crappy code! For fucks sake!15 -
So I've decided to go about converting a Java project that I've been working on to Kotlin a little bit at a time. I started out with basic entity classes converting them to simple `data class`es in Kotlin.
Eventually, I got to my first beast of a class to refactor. This class had over 40 service classes depending on it, so even a little hiccup would throw everything into chaos.
I finish all of the changes on all of the dependent classes, update the tests, and the configurations (as necessary), and I was finally ready to spin up the app to test for any breaking changes I may have introduced...
Well - I broke everything! But I was sure I couldn't have! So what the hell happened?
Turns out that as I was building my project with a Gradle watch, at one point something failed to compile, which threw an unhandled exception in the gradle daemon that was never reported.
So when I tried to run my app, gradle would continually re-throw the error in the app I asked it to run...
After turning the daemon off and on again, the app worked like a charm.

I’ve been programming with other languages than Python for so long that when I finally had to pick up Python to help teach my friend some python I felt like I was rediscovering a past life.
With Python I feel like King Fucking Arthur with the Holy Blade Excalibur, armored up and ready for fucking war.
When I’m writing a script I feel like I’m parrying and piercing my blade straight through that fuckers chest and slam them into the fucking ground. And leave their bleeding out cold dying body on the fucking ground with no hope in their eyes.
Although when an indentation error occurs I feel like I just fucking tripped over a fucking pebble and apparently stairs were nearby and I bash my head on all 1024 steps, get to the bottom to just to get some fucking Java Chad punt my fucking head like a fucking football screaming random reasons to not use python.7 -
For the love of god, I spent 2,5 hours debugging why Minecraft from the windows store doesn't work...
The game just shows a red message telling you it didn't work.
I checked the logs, nothing just warnings
I re-installed the game, nothing, same error
Updated java and all parts of the store, nothing....
Obviously I had to install Something called the "xbox identity Provider"... You know... On a PC... For a distinctly PC game to work... Installed by the store... And the provider is also on the store... But it doesn't auto-install with the game
Ever since you migrated to the Microsoft Auth the login experience is awful (I ranted about that already)
How about you do the bare fucking Minimum of an User experience and Install the fucking dependencies when I re-installed something your fucking store??!!!
The fucking bare minimum that every package manager ever created fucking has as a basic requirement?! Are you kidding me?

In school we had to write some code in Java and before the lessen one of my friends said to me that he already knew Java and that it was like a very easy coding language.
Then, when we actually had to code, he was complaining that his code didn't work.
So I stopped coding, stood up and walked over to him. He had only very few lines of code and after reading the error message I told him that he was missing a semicolon in line X.
He then asked me what a semicolon was. At that moment I thought: Oh, it's just that one thing that you put after ALMOST EVERY LINE OF CODE IN JAVA. I showed him where I find it on the keyboard and then I fixed his code (it had way more errors than just a missing semicolon).
I have no problem with helping other people but if that person brags about how well they know Java and then not knowing what a semicolon was, that's just not ok.2 -
Is it just me who sees this? JS development in a somewhat more complex setting (like vue-storefront) is just a horrible mess.
I have 10+ experience in java, c# and python, and I've never needed more than a a few hours to get into a new codebase, understanding the overall system, being able to guess where to fix a given problem.
But with JS (and also TS for that matter) I'm at my limits. Most of the files look like they don't do anything. There seems to be no structure, both from a file system point of view, nor from a code point of view.
It start with little things like 300 char long lines including various lambdas, closures and ifs with useless variables names, over overly generic and minified method/function names to inconsistent naming of files, classes and basically everything else.
I used to just set a breakpoint somewhere in my code (or in a compiled dependency) wait this it is being hit and go back and forth to learn how the system state changes.
This seems to be highly limited in JS. I didn't find the one way to just being able to debug, everything that is. There are weird things like transpilers, compiler, minifiers, bablers and what not else. There is an error? Go f... yourself ...
And what do I find as the number one tipp all across the internet? Console.log?? are you kidding me, sure just tell me, your kidding me right?
If I would have to describe the JS world in one word, I would use "inconsistency". It's all just a pain in the ass.
I remember when I switcher from VisualStudio/C# to Eclipse/Java I felt like traveling back in time for about 10 years. Everyting seemd so ... old-schoolish, buggy, weird.
When I now switch from java to JS it makes me feel the same way. It's all so highly unproductive, inconsistent, undeterministic, cobbled together.
For one inconveinience the JS communinity seems to like to build huge shitloads of stuff around it, instead of fixing the obvious. And noone seems to see that.
It's like they are all blinded somehow. Currently I'm also trying to implement a small react app based on react-admin. The simplest things to develop and debug are a nightmare. There is so much boilerplate that to write that most people in the internet just keep copying stuff, without even trying to understand what it actually does.
I've always been a guy that tries to understand what the fuck this code actuall does. And for most of the parts I just thing, that the stuff there is useless or could be done in a way more readable way. But instead, all the devs out there just seem to chose the "copy and fix somehow-ish" way.
I'm all in for component-izing stuff. I like encapsulation, I'm a OOP guy by heart. But what react and similar frameworks do is just insane. It's just not right (for some part).
Especially when you have to remember so much stuff that is just mechanics/boilerplate without having any actual "business logical function".
People always say java is so verbose. I don't think it is, there is so few syntax that it almost reads like a prose story. When I look at JS and TS instead, I'm overwhelmed by all the syntax, almost wondering every second line, what the actual fuck this could mean. The boilerplate/logic ration seems way to off ..
So it really makes me wonder, if all you JS devs out there are just so used to that stuff, that you cannot imagine how it could be done better? I still remember my C# days, but I admin that I just got used to java. So I can somehow understand that all. But JS is just another few levels less deeper.
But maybe I'm just lazy and too old ...4 -
One time, I was working with an org that got a new senior executive from Microsoft. He decided we needed to throw out our application's java stack and replace it with SharePoint. The code error was committing anything other than my immediate resignation.4
-
I realized why do i like java the most. Error messages are easy to read and consistent. Never really had to look up an error because the message tells you exactly what is wrong. Hell, you could write a script to self-repair the errors because they are so obvious to fix.
Now compare that to my current stack, python and js....8 -
Porting Java Code to Kotlin manually, just to get a better understanding of the language. Best thing so far, NO more Assertive Exception Handling.
Damnit Java, I know it for a fact that the damned thing won't throw an exception! There's Careful and Paranoid. KNOW THE DIFFERENCE

There was an error in one of my Java file. Impossible to find it. I commented all the code and the error remain. I commented the import of that class and no more error. How the f**** is possible that a empty class give an error ?
I opened the file in another text editor and found out that the last character was a symbol that wasn't recognize or display in other text editor.
I was really proud (and confused)3 -
I started my internship at the end of the year..
Fuck my ass!!! This code I have to work with is a huge pile of shit.
The code base I need to work with is around 40k LOC. It is a mixture of C++, C, Java, Python, Bash and I think I saw some lonely js files around.
A list of awesome parts:
- Paths are hard coded.
- Redundant code everywhere
- No documentation or inline comments available
Most of the comments in the code are just old code that is not used anymore. But the cherry on the turd is the class that should provide all kind of useful functions in my daily routine. About ninety percent of the functions have the same description or nothing. Sometimes a function name says "readSomethingFromSomewhere" but instead it writes something to a file. It is really confusing and I need to check everything twice instead of rely on what the function name promises.
I have also learned why copy paste isn't that good. The brief descriptions of every method in a files are always the same.
getName() - Description: Fork child process
getIp() - Description: Fork child process
getIpv6() - Description: Fork child process.
Surprise: None of these functions forks a child process. :D
Another awesome feature is the thing that they store up to five different versions of libraries. Everyone with slight modifications but no hint which one you need to use. Sometimes it is the newest, sometimes the oldest which is running in production. Another case of try and error.
Oh and my dev machine is a potato with a power supply and a fan. I started with NetBeans and every time I compiled the code it sounds like the machine wants to lift off and leave for a better place. (At this point I switched to Emacs and everything runs smoothly now)
At first I thought that I'm just not that good at coding and understanding a big project from scratch but some colleagues have the same problem. The whole system is very inflexible and it is all about "std::cout"-debugging to check if your changes do what you want them to do.
Currently I'm just trying to fix this mess to make the life for the next student or employee easier. The first month was just frustrating as hell. I need to ask so many questions and most of the time the answer was "I don't know, haven't touched this code in years". Needless to say that my progress isn't that awesome but at least I get a nice payment for 20 hours of work a week.2 -
Got rebuked by the Java teacher today at the University for using proper long names for variables in the code. She though I was just wasting time being lazy in the lab. "If something can be achieved by a single character, why type that long variable again and again?". *Everyone in class laughs*
Then, there was an error in my code [turned out to be long long int in Java is weird], and I had no clue what was going wrong [I'm a week old in Java]. So, I had initially called her to help. She made me change all private methods and attributes to public. When asked "why?", got trolled again.
Now, I know it's okay, and not that I really care about what my classmates think of me, but getting this kind of treatment really sucks. And if this is how future software developers are crafted today, maintainability is surely going to be an issue tomorrow.
Maybe staying in this stupid country was my worst career choice. I should have tried harder and gone abroad.11 -
Today was a manic-depressive kind of day. Spent the morning helping some developers with getting their code to run a stored procedure to drop old partitions, but it wasn't working on their end. It was a fairly simple proc. But working with partitions is a little like working with an array. I figured out that they were passing the wrong timestamp, and needed to add +1 to delete the right partition. Got that sorted out, and things were good. Lunch time.
After lunch I did some busy work, and then the PO comes up at about 2PM and says he's assigned some requests to me. The first was just attaching some scripts. Easy. The second, the user wants a couple of schemas exported ... at 6PM. I've been in the office since 6:45AM.
While I'm setting up some commands to run for the data export, a BA walks up and asks if I'm filling in for another DBA who is out for a few weeks. Yep. There's a change request that hasn't been assigned, and he normally does the work. I ask when it's due. Well, the pre-implementation was supposed to be done in the morning, but it wasn't, and we're in the implementation window ... half way through. I bring up the change task, and look at. Create new schema and users. That's all it says. The BA laughs. I tell I need more to go on. 10 minutes later he sends an email with the information. There's only two hours left in the window, and I can only use half of it, because the production guys have to their stuff, and we're in their window. Now I'm irritated, because I'm new to Oracle, and it's an unforgiving mistress. Fortunately, another DBA says he'll do it, so that we can get it done in time. But can't work it either, because Dev DBAs don't have access to QA, and the process required access for this task. Gets shelved until the access issue is resolved. It's now after 4:15PM. I'm going to in traffic with that 6PM deadline.
I manage to get home and to the computer by 5:45PM. Log in. Start VPN. Box pops on screen. Java needs to update. I chose skip update. Box pops up again. It won't let me log in until Java is current. Passed.
I finally get logged in, and it's 6:10PM. I'm late getting the job started. I pull up Putty and log into the first box, and paste my pre-prepared command in the command line and hit error. Command not found. I'm tired, so it's a moment to sink in. I don't have time for this.
I log into DBArtisan and pull up the first data base, use the wizard to set the job, and off it goes. Yay. Bring up the second database, and have enter the connect info. Host not found. Wut? Examine host name. Yep, it's correct. Try a different method. Host not found. Go back to Putty. Log in. Past string. Launch. Command not found. Now my brain is quitting on me. Why now? It's after 6:30PM. Fiddle with some settings, reset $Oracle home. Try again. Yay. It works. I'm done. It's after 7PM.
There is nothing like technology to snatch the euphoria of a success away from you. It's a love-hate thing, but I wouldn't trade it for anything else. I'm done. Good night.3 -

Fucking hell everything in java is so annoying, confusing and hard to get working. I just want to use JavaFX, why do you require me to sacrifice a lamb in order to do so? It might be my fault though, but c'mon, I don't want to spend 2-3 hours reading through shitty documentation in order to understand how maven works and what the hell Gradle is. Why can't it be as simple as adding a module name to a config file, like in Rust's Cargo? Even using intellij to acquire JavaFX and set it as a dependency doesn't work, it gives me some weird "JavaFX not configured" bullshit error. What the fuck, you're a library, you shouldn't need anything else ffs6

Running a fucking conda environment on windows (an update environment from the previous one that I normally use) gets to be a fucking pain in the fucking ass for no fucking reason.
First: Generate a new conda environment, for FUCKING SHITS AND GIGGLES, DO NOT SPECIFY THE PYTHON VERSION, just to see compatibility, this was an experiment, expected to fail.
Install tensorflow on said environment: It does not fucking work, not detecting cuda, the only requirement? To have the cuda dependencies installed, modified, and inside of the system path, check done, it works on 4 other fucking environments, so why not this one.
Still doesn't work, google around and found some thread on github (the errors) that has a way to fix it, do it that way, fucking magic, shit is fixed.
Very well, tensorflow is installed and detecting cuda, no biggie. HAD TO SWITCH TO PYHTHON 3,8 BECAUSE 3.9 WAS GIVING ISSUES FOR SOME UNKNOWN FUCKING REASON
Ok no problem, done.
Install jupyter lab, for which the first in all other 4 environments it works. Guess what a fuckload of errors upon executing the import of tensorflow. They go on a loop that does not fucking end.
The error: imPoRT eRrOr thE Dll waS noT loAdeD
Ok, fucking which one? who fucking knows.
I FUCKING HATE that the main language for this fucking bullshit is python. I guess the benefits of the repl, I do, but the python repl is fucking HORSESHIT compared to the one you get on: Lisp, Ruby and fucking even NODE in which error messages are still more fucking intelligent than those of fucking bullshit ass Python.
Personally? I am betting on Julia devising a smarter environment, it is a better language already, on a second note: If you are worried about A.I taking your job, don't, it requires a team of fucktards working around common basic system administration tasks to get this bullshit running in the first place.
My dream? Julia or Scala (fuck you) for a primary language in machine learning and AI, in which entire environments, with aaaaaaaaaall of the required dlls and dependencies can be downloaded and installed upon can just fucking run. A single directory structure in which shit just fucking works (reason why I like live environments like Smalltalk, but fuck you on that too) and just run your projects from there, without setting a bunch of bullshit from environment variables, cuda dlls installation phases and what not. Something that JUST FUCKING WORKS.
I.....fucking.....HATE the level of system administration required to run fucking anything nowadays, the reason why we had to create shit like devops jobs, for the sad fuckers that have to figure out environment configurations on a box just to run software.
Fuck me man development turned to shit, this is why go mod, node npm, php composer strict folder structure pipelines were created. Bitch all you want about npm, but if I can create a node_modules setting with all of the required dlls to run a project, even if this bitch weights 2.5GB for a project structure you bet your fucking ass that I would.
"YOU JUST DON'T KNOW WHAT YOU ARE DOING" YES I FUCKING DO and I will get this bullshit fixed, I will get it running just like I did the other 4 environments that I fucking use, for different versions of cuda and python and the dependency circle jerk BULLSHIT that I have to manage. But this "follow the guide and it will work, except when it does not and you are looking into obscure github errors" bullshit just takes away from valuable project time when you have a small dedicated group of developers and no sys admin or devops mastermind to resort to.
I have successfully deployed:
Java
Golang
Clojure
Python
Node
PHP
VB/C# .NET
C++
Rails
Django
Projects, and every single fucking time (save for .net, that shit just fucking works on a dedicated windows IIS server) the shit will not work with x..nT reasons. It fucking obliterates me how fucking annoying this bullshit is. And the reason why the ENTIRE FUCKING FIELD of computer science and software engineering is so fucking flawed.
But we can't all just run to simple windows bs in which we have documentation for everything. We have to spend countless hours on fucking Linux figuring shit out (fuck you also, I have been using Linux since I was 18, I am 30 now) for which graphical drivers for machine learning, cuda and whatTheFuckNot require all sorts of sys admin gymnasts to be used.
Y'all fucked up a long time ago. Smalltalk provided an all in one, easily rollable back to previous images, easily administered interfaces for this fileFuckery bullshit, and even though the JVM and the .NET environments did their best to hold shit down, and even though we had npm packages pulling the universe inside, or gomod compiling shit into one place NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO we had to do whatever the fuck we wanted to feel l337 and wanted.
Fuck all of you, fuck this field, fuck setting boxes for ML/AI and fuck every single OS in existence2 -
I did mostly Java and JavaScript coding before I came to my current job. When I started I pretty much had to learn PHP on the fly. Pretty much no problems, but my greatest shame from the few years I've been writing code is when I spent over an hour debugging an unknown error, after which time a fellow dev looked at my code and informed me that PHP uses . instead of + to concatenate strings...6

Short rant: I hate xcode, I hate Swift, I hate Apple.
After 3 weeks of intensive work (I'm an apprentice, part-student, part-worker), I was happy to go back to school and was like "Oh we're going to learn iOS, sounds cool !".
It is now friday, I have homicidal tendencies growing inside me, I want to cry whenever I hear xcode or swift.
Why in the hell I can't use a string argument when I'm calling a function NEEDING a string arg ?
Why do xcode take so long to tell me that there is a problem, why is the error message not explicit AT ALL ?
Why dictionaries so hard to manipulate, EVEN IN JAVA IT'S SIMPLIER.
Why putting our API call in specialized files make them run AFTER EVERYTHING ELSE and the solution that is given to us is deprecated since 5 years ?
Why is a classic c-style for loop is now deprecated ?
These are just a drop in the ocean of WHAT THE FUCK IS THAT that we came across this week.
Fuck Swift, fuck xcode.

So recently I needed to make a little Tic-tac-toe game with Node.JS for an university project. I previously learned Java and C# so Javascript as a non-compiled, script based language was something new for me.
Now during the programming process I reached the point where I needed to implement a function to change the player who's playing.
I was testing the game and... It seemed like the player was changed twice so it immediately switched back to the previous player.
Using a lot of console.log's I finally stumbled upon the error... (since Javascript or at least Visual Studio Code, I honestly don't know, doesn't have any kind of debugger or something).
Why the fuck does js allow to make allocations in if conditions?
I accidentally wrote one '=' instead of three '==='.
No error, no warning... Nothing.
Since then js and me are not friends anymore.8 -
I'm so done with flutter.
I wanted to give it a little try by rewriting a small android project I wrote a few years back. It brings some nice concepts especially when it comes to UI related programming but that's all I can really compliment it for. It's nothing more than something to play with as it is right now.
Also I think this text will be hidden behind the read more. Did I successfully bait you with that cat?
The things I truly hate about it:
The ide integration makes me wanna use eclipse again. At least most nonsensical error messages disappear after saving the document on eclipse.
.
Wanna generate a new function? Yeah, let me just place it RIGHT INSIDE THIS FUCKING IMPORT STATEMENT
Over at Google: Let's just rename everything from java slightly different and put it in nonsensical context so that you have to learn all of it again. Also why don't we make it so that the code suggestions only suggest things you already imported, so that you have to look up every little piece shit feature.
When it comes to databases, I must say, I had more fun working with PHP and mysql than with sqFUCKlite. Throwing away the Room components for that? What a joke...
I already said what i think about the syntax here an devrant but I'm more than happy to repeat it here:
The syntax looks like someone looked at C#, Java and JavaScript and then decided to vomit the worst parts of it into a programming language. I can't really classify anything original about it. There are clear inspirations, but they are confusingly mashed together with the other languages making this one nuts of a language.
Android SDK documentation is a blessing in comparison to whatever the fuck flutter tries to do.
I don't think I'll want top touch that Google side project again within the next few years, if it hasn't been replaced with a new side project like billiard by then.

I'm here in my bed. I can't sleep and in less than 5 hours I will have an important exam. I was thinking that a few months ago I went to a IT company as a school program. I would have to stay there for 2 weeks and "work" for them.
Upon arrival, the guy who had to monitor me gave me a sheet of paper with 5 alghoritmic problems to solve. He tells me to use java and hands me a laptop. naturally with windows. I try to look for some ideas but I can not find anything. I go to the control panel and search for something. Obviously there is a lot of bloatware and nothing catches my attention. then strangely I find something called oracle ... something ... but when trying to open it it gives me an error.
Fuck me. I decided to open notebook(normal one not ++ or something) and start solving the problems trying to remember the names of the methods and the classes based on what I had learned in school. then the guy comes back and looks at me puzzled. I tell him I did not find any IDE for java and the only one I found seem to give me an error. The guy double clicks and the program opens...fucking shit... He tells me to finish the problems and goes away perplexed. I copy the code from notepad to the IDE, I check the errors, I run it and the add some comments and I call the guy. he looks at the code, says that everything seems fine and then assigns me other things to do.
Now. HOW FUCKING STUPID MUST SOMEONE BE TO THINK THAT WRITING JAVA IN NOTEPAD IS A VIABLE CHOICE, AMONG ALL THE POSSIBLE SANE CHOICES I COULD HAVE MADE LIKE TRY TO UNDERSTAND THE ERROR OF THE IDE OR CALL THE GUY... NO. MY LITTLE SHOTTY FUCKING BRAIN DECIDED THAT NOTEPAD WAS A GOOD CHOICE. IF I COULD GO BACK IN TIME IN THE SAME MOMENT THAT I OPENED NOTEPAD I WOULD BITCH SLAP MYSELF SO HARD THAT I WOULD LOSE MY SOULD AND THE LAST 2 NEURON THAT MADE THAT SHITTY CHOICE. I WOULD BITCH SLAP MYSELF SO HARD THAT THE KINETIC ENERGY PRODUCED WOULD COLLAPSE THE UNIVERSE ITSELF. AND FROM THE DARKNESS A NEW UNIVERSE WILL BE BORN. A UNIVERSE WHERE THERE IS NO JAVA OR WINDOWS. A UNIVERSE WHERE MY 2 NEURONS WOULD HAVE MADE THE SHITTIEST DUMBEST CHOICE EVER IN A I LAST MISERABLE SELF DESTRUCTIVE ATTEMPT.
but then I come on devrant and I read about people who did thing worse than writing java on notepad and then everything is fine
PS my English is so bad I had to use Google translate, write an original version, translate it and do a side by side comparison with my translated version to check If I could improve something. Don't now If It improved the quality or not...3 -
I actually never felt the need to scream at a co-worker so let's talk about that time a co-worker screamed at me instead.
tl;dr : some asshole boss screamed and threatened me because someone else's project was shit and didn't work.
Context: I was in my third year of school internship (graded) and my experience is C, C++, C#, Python all in systems programming, no web.
I was working as an intern for a shit company that was selling a shit software to hospitals (though not medically critical, thank God) the only tech guy on site was the DBA (cool guy) the product was maintained by a single dev in VB from his house, the dude never showed up to work (you'll understand why) and an other intern who couldn't dev shit.
I was working with the DBA on an software making statistical analysis from DB exports, worked nice, no problems here if we forget the lack of specs or boundaries (except must work in ieShit).
The other intern was working on something else (don't ask me what it is) I just remember it was in GWT before the community revived it. His webapp was requesting the company http server for a file instead of having one of it's java servlet to fetch it (both apps ran on sane server) which caused a lot of shit especially CORS error. That guy left (end of contract) and leaves his shit as is, boss asked me to deploy the app, I fiddle with it to see if it works and when I find out it doesn't then that asshole starts screaming at me in front of every other employee present, starts threatening to burn me in the tech world and have me thrown out of my school for no goddamn reason than the other dude's project doesn't work.
After the screaming I leave and warn my school immediately.
I guess that's why the other dev never came to work.
I had three weeks of internship left, that I did from home and worked probably less than 2 hours a day so suck it asshole.
Still had a good grade because I was reviewed by the DBA and he was happy with the work I did.
It was only later that I realized that what he did was categorizing as harassment (at least in France) and decided that never again this would happen without a response from my lawyer.1 -

I am learning java at school and my teacher asked me to make a work on JTA (java transaction API). There's not a lot of tutos on it on the web so I say to myself "go on, give it a try, you'll only learn by trying."
I finally find how to make the @TransactionType, where to put the @Stateless, my test works, nice. Finally I want to try a case where it shouldn't work, just to be sure the rollback works well. The test goes and... NullPointerException. Wtf ! Normally, my catch is supposed to, well, catch the error !
And finally, I was just stupid. My catch worked great. But I put a "throw e" inside.
Now I wanna hides under blankets, cry, eat cake and never see my coworkers again.2 -

I often read articles describing developer epiphanies, where they realized, that it was not Eclipse at fault for a bad coding experience, but rather their lack of knowledge and lack of IDE optimization.
No. Just NO.
Eclipse is just horrendous garbage, nothing else. Here are some examples, where you can optimize Eclipse and your workflow all you like and still Eclipse demonstrates how bad of an IDE it is:
- There is a compilation error in the codebase. Eclipse knows this, as it marks the error. Yet in the Problems tab there is absolutely nothing. Not even after clean. Sometimes it logs errors in the problems tab, sometimes t doesn't. Why? Only the lord knows.
- Apart from the fact that navigating multiple Eclipse windows is plain laughable - why is it that to this day eclipse cannot properly manage windows on multi-desktop setups, e.g. via workspace settings? Example: Use 3 monitors, maximize Eclipse windows of one Eclipse instance on all three. Minimize. Then maximize. The windows are no longer maximized, but spread somehow over the monitors. After reboot it is even more laughable. Windows will be just randomly scrabled and stacked on top of each other. But the fact alone that you cannot navigate individual windows of one instance.. is this 2003?
- When you use a window with e.g. class code on a second monitor and your primary Eclipse window is on the first monitor, then some shortcuts won't trigger. E.g. attempting to select, then run a specific configuration via ALT+R, N, select via arrows, ALT+R won't work. Eclipse cannot deal with ALT+R, as it won't be able to focus the window, where the context menus are. One may think, this has to do with Eclipse requiring specific perspectives for specific shortcuts, as shortcuts are associated with perspectives - but no. Because the perspective for both windows is the same, namely Java. It is just that even though Shortcuts in Eclipse are perspective-bound, but they are also context-sensitive, meaning they require specific IDE inputs to work, regarldless of their perspective settings. Is that not provided, then the shortcut will do absolutely nothing and Eclipse won't tell you why.
- The fact alone that shortcut-workarounds are required to terminate launches, even though there is a button mapping this very functionality. Yes this is the only aspect in this list, where optimizing and adjusting the IDE solves the problem, because I can bind a shortcut for launch selection and then can reliably select ant trigger CTRL+F2. Despite that, how I need to first customize shortcuts and bind one that was not specified prior, just to achieve this most basic functionality - teminating a launch - is beyond me.
Eclipse is just overengineered and horrendous garbage. One could think it is being developed by people using Windows XP and a single 1024x768 desktop, as there is NO WAY these issues don't become apparent when regularily working with the IDE.9 -
I know its been quite a while since ive posted last but it is safe to say that i am back! And boy do i have some stuff to bitch about.
This semester, Im taking mobile app development as a class. I chose to take this class over the introductory c# class, so that i wouldn't need to work with Windows or really do anything else to touch Windows. Well the joke is on me. Here i was thinking that we would be using a bit of Java from time to time while only really learning best practices and concepts.
Never did i think that this class's curriculum would be entirely based off of Xamarin.
Seeing as I need either this class or the two c# classes to graduate, I had to bite the bullet and just accept that my semester would be full of irritation during this class.
Its been about seven weeks in, and i have turned in 8 assignments.
All 8 of those assignments have been Windows Form Applications doing simple shit like dividing two numbers.
We have not made anything for multiple devices. We have not made anything for even one mobile device. We have not even discussed how to do this in the class.
This wouldnt bother me so much since these are typically easy programs that take about 30 minutes to make and test and submit for grading. It does insanely bother me, however, that it takes Windows so FUCKING LONG to boot, or when it freezes every 2 minutes because i clicked into another program, or it just HANGS ON THE UPDATING SCREEN AT 36% FOR THREE DAYS, or when it took 4 different reinstallations of Visual Studio 2017 before i could actually open without an error code.
College, Ive learned, tests my patience way more than it has ever tested my knowledge.2 -
"Error: Program type already present"
So f--ing what? Ignore the doublon and MOVE ON WITH THE COMPILE, JAVA! -
coded a java program in eclipse throws back error .
Know that program is correct.
Created a new project file copy pasted the code, wolaa.. executed.

i hate people who join the company with a engineering in computer science degree and then can't even setup freaking java on their system.
like that is one of the basic languages taught to programmers, how do you graduate CS yet not know how to setup java!!!!!
this idiot today tired setting up eclipse without java and got errors and comes to me saying your files are corrupt.... i ask what happens and he shows me a error message box saying cannot find java paths... and then says i keep getting this error!!!
like freaking read the damn error and fix it. you're an engineering graduate for gods sake!!!!10 -
Was recently asked if our team wanted to change from Java to Kotlin so I looked over the feature lists but don't see much that's impressive.
One argument was less boilerplate code but I think they're are libraries like Lomboq that can write that stuff for you.
The other was smart type casting and type inference and to that I'm like this sounds like giving monkeys a hammer.
Our JS codebase looks like shit... And our Java app just crashed in prod.
Getting a ton of text messages this morning and thankfully I'm on vacation still...
The error is not caused by NPE... but how some or logic spammed the db..
A new language isn't going to fix this.... And a team that writes this sort of shit logic clearly shows they are incapable of learning a new one probably...
They are already script kiddies... Don't need them to become babies...6 -
I need some opinions on Rx and MVVM. Its being done in iOS, but I think its fairly general programming question.
The small team I joined is using Rx (I've never used it before) and I'm trying to learn and catch up to them. Looking at the code, I think there are thousands of lines of over-engineered code that could be done so much simpler. From a non Rx point of view, I think we are following some bad practises, from an Rx point of view the guys are saying this is what Rx needs to be. I'm trying to discuss this with them, but they are shooting me down saying I just don't know enough about Rx. Maybe thats true, maybe I just don't get it, but they aren't exactly explaining it, just telling me i'm wrong and they are right. I need another set of eyes on this to see if it is just me.
One of the main points is that there are many places where network errors shouldn't complete the observable (i.e. can't call onError), I understand this concept. I read a response from the RxSwift maintainers that said the way to handle this was to wrap your response type in a class with a generic type (e.g. Result<T>) that contained a property to denote a success or error and maybe an error message. This way errors (such as incorrect password) won't cause it to complete, everything goes through onNext and users can retry / go again, makes sense.
The guys are saying that this breaks Rx principals and MVVM. Instead we need separate observables for every type of response. So we have viewModels that contain:
- isSuccessObservable
- isErrorObservable
- isLoadingObservable
- isRefreshingObservable
- etc. (some have close to 10 different observables)
To me this is overkill to have so many streams all frequently only ever delivering 1 or none messages. I would have aimed for 1 observable, that returns an object holding properties for each of these things, and sending several messages. Is that not what streams are suppose to do? Then the local code can use filters as part of the subscriptions. The major benefit of having 1 is that it becomes easier to make it generic and abstract away, which brings us to point 2.
Currently, due to each viewModel having different numbers of observables and methods of different names (but effectively doing the same thing) the guys create a new custom protocol (equivalent of a java interface) for each viewModel with its N observables. The viewModel creates local variables of PublishSubject, BehavorSubject, Driver etc. Then it implements the procotol / interface and casts all the local's back as observables. e.g.
protocol CarViewModelType {
isSuccessObservable: Observable<Car>
isErrorObservable: Observable<String>
isLoadingObservable: Observable<Void>
}
class CarViewModel {
isSuccessSubject: PublishSubject<Car>
isErrorSubject: PublishSubject<String>
isLoadingSubject: PublishSubject<Void>
// other stuff
}
extension CarViewModel: CarViewModelType {
isSuccessObservable {
return isSuccessSubject.asObservable()
}
isErrorObservable {
return isSuccessSubject.asObservable()
}
isLoadingObservable {
return isSuccessSubject.asObservable()
}
}
This has to be created by hand, for every viewModel, of which there is one for every screen and there is 40+ screens. This same structure is copy / pasted into every viewModel. As mentioned above I would like to make this all generic. Have a generic protocol for all viewModels to define 1 Observable, 1 local variable of generic type and handle the cast back automatically. The method to trigger all the business logic could also have its name standardised ("load", "fetch", "processData" etc.). Maybe we could also figure out a few other bits too. This would remove a lot of code, as well as making the code more readable (less messy), and make unit testing much easier. While it could never do everything automatically we could test the basic responses of each viewModel and have at least some testing done by default and not have everything be very boilerplate-y and copy / paste nature.
The guys think that subscribing to isSuccess and / or isError is perfect Rx + MVVM. But for some reason subscribing to status.filter(success) or status.filter(!success) is a sin of unimaginable proportions. Also the idea of multiple buttons and events all "reacting" to the same method named e.g. "load", is bad Rx (why if they all need to do the same thing?)
My thoughts on this are:
- To me its indentical in meaning and architecture, one way is just significantly less code.
- Lets say I agree its not textbook, is it not worth bending the rules to reduce code.
- We are already breaking the rules of MVVM to introduce coordinators (which I hate, as they are adding even more unnecessary code), so why is breaking it to reduce code such a no no.
Any thoughts on the above? Am I way off the mark or is this classic Rx?16 -
So my coworker was trying to `npm install` after I recently installed Ubuntu on her machine and for some reason , I was doing something else, some jdk not being installed error popped on her screen.
She proceeded to have a mini freak out telling me that npm wasn't working because java wasn't installed and I started hysterically laughing in the middle of the office with my boss next to her staring at me... So I said firmly ( while laughing ):
"no bahuhaahah that's not hahahaha the case."
Still can't understand wtf she thinks happens with stuff in a computer... Cmon... -
I read the other day here about people not reading the error messages shown by the IDE and thought "there can't be people this dumb..."
Well, today I was helping a friend out with his java project and he was trying to figure out an error for at least 10 min so I told him, read the error message, he goes like nah, that won't help, I kept repeating it till he did it and guess what? The explanation was there and helped him figure out the problem.
His excuse? He didn't have the patience to read the message, it was 2 lines long...
How can you be so stupid to the point where your first thought isn't checking out the damn message the IDE gives you? It's there for a fucking reason.1 -
Just had a class where we had to write a heap adding algorithm in Java to reduce rounding error for x amount of floats being added together
After an hour of writing code with no testing anything I finished. Ran the JUnit tests provided by the teacher and it passed all the tests!
Who says it can't work the first time?

It was in old days when I was working in java and windows systems.
Java and different log4j versions across dependencies caused system not working only on production server.
Turned out some of libraries got log4j embedded and conflicted with other log4j.
It worked in all computers except production one.
Actually that was my main reason to switch my career to python after that dependency hell.
Another one was windows server 2008 tcp connection limit set to 200 or something.
We needed to change registry to get our servers working. After this case we finally managed to convince people to switch to linux.
Anyway any non standard error when you got multiple layers communicate with each other is hard, practice make it easier to solve those problems as your success moment comes faster.4 -
Here's the description of java.lang.NoSuchMethodError from https://developer.android.com/refer...
"...Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed."
Now, what are the chances of your app crashing on customer's device because of this, when calling an OS function, VibrationEffect.createPredefined(VibrationEffect.EFFECT_DOUBLE_CLICK)? In my case, it's 50/50. Lesson learned Google. try{}catch{} around every line of code from now on to deal with your stupidity.4 -

WTF?! I just dunno how to handle this error message.

Eh What!? I mean what?!
Will someone please catch that? I'll throw it to you...

Built my first App - the BOFH returns
So I started to learn programming about 7 weeks ago, learned some Java, immersed myself in git and then via a friend got introduced to android studio. To get some practice I decided to code my own app, and what better way than to create a quote generator for the funny and creative error messages as seen in The Bastard Operator from Hell. Now I wrote the thing, started adding a feature and before I know it, it works and I'm contacting the original author, if I may publish it to the playstore.
Io and behold: Merely 32 hours after the idea had sparked, in an act of spontaneous madness I've pubished my first app.
This was an absolutely electrifying experience and a huge feeling of success to me, to see my own creation on my homescreen.
Sorry for annoying you with this antirant, but I just had to get this out!
Btw here's the link if anyone is interested:

Funny story...
Got a small college assignment based on Java and Cassandra(database). The database shell was running fine. Spent 5 days removing the random java exceptions and working on the basic connectivity, searched everywhere on Stack overflow and other forums for solutions and still no help.
So, I decided to write a program that would print only the output as I knew what would be the output when it will run. Took a screenshot of it and made up a cover story to tell my professor that I did it on a friend's computer.
But while I was taking a screenshot of the Eclipse with code window and output window, some random syntax errors popped up.(but they weren't syntax error).
So I created a new project and copied the pom.xml file and the code into the new one(I tried this one before and it didn't work). And there were no errors. So I took a screenshot of it with output of different file and opened a different file.
But then, don't know what came across my mind and I clicked on run just to see if this works, and it worked fine. And now I'm like.. WTF JUST HAPPENED!! -
So, I decided over the weekend that I would move my entire dev environment to Linux. No Windows on the laptop and only as a backup boot system for my home PC. I wanted to wean myself off of Linux as only being a VM and move to the full blown desktop.
I can only describe my experience to that of having your first kid: lot's of crying and joy at the same time.
Things I've learned:
1. The install is amazingly painless. Wi-Fi and Bluetooth work straight out of the box no configuring needed.
2. OH MY GOD THE CUSTOMIZATION. Rocking Arc Dark theme on Gnome3 = EVERYTHING IS
ALWAYS DARK MICROSOFT WHY IS THIS NOT A THING.
3. Getting Java servlets to work has been hell. I gave up trying to get them to work in eclipse and moved over to IntelliJ. More trial and error before I can figure out why tomcat won't fucking work in eclipse but it's fine in IntelliJ.
4. The UI and overall work flow has been improved after getting past the learning curve. Gnome3 is way better from when I tried it out 4 years ago.
5. Vim has a steep learning curve but I am starting to understand the net benefits of it. It'll probably be a solid month before I get good with it.
6. Loosing Microsoft Office has been a little bit of a challenge but their suite is online so....meh. I do miss Visual Studio though, and am still looking for an adequate replacement for C++ and C# development.
Overall it's been a challenge but I think it's been a net gain. Now if only I could get the whole sys-admin team to use it. ;)

Let me start this off by stating I'm a Java dev, and a noob with C++.
Thought it'd be cool to learn some OpenCL, since I want to do some maths stuff and why not learn something new.
So I sat down, installed Nvidia proprietary drivers, broke my x-org server, purged, reinstalled, rebooted and after a while I got stuff sorted out.
Then on to my IDE. I use CLion and it uses Cmake. C++ noob knows shit about Cmake, so struggle for two hours trying to figure out wtf is going on with the OpenCL libs and why they're only partially detected. Fml.
Finally, everything is configured and I'm set. I start working on a Hello World program using OpenCL. Finish it in 20 mins, all good. No output. Do some googling, check my program a million times. Nothing wrong here. Check the kernel, everything as in the tutorial.
I start checking error codes after a while reported by OpenCL (which I had no clue was a thing) and I get some code saying the program was not created properly (to run the kernel). No fucking clue what's up with that. Google around, find another tutorial, rewrite my code in case I'm using outdated code or something. Nothing.
Fast forward an hour, I find out that OpenCL has logs! So I grab some code from the website I found it on, and voila, I finally get some info on what's going on.
Get a load of this bs.
In the kernel file, so that OpenCL knows that it's a function to run, you have to put __kernel. But in all the places I read, it said to put it as _kernel.
Add the underscore, compile, run and everything is perfect.
Then I tried just putting 'kernel'. Also compiles and runs fine.
Two hours hours and my program was fixed by adding an underscore. IF ONLY C++ GAVE AN INDICATION OF WHAT BLEW UP INSTEAD OF SITTING BACK AND BEING LIKE "oh wow man feels bad, work some magic and try again" THEN THIS WOULD NOT HAVE TAKEN SO LONG.
Then again, it was OpenCL that was being shitty with its styling enforcement or whatever the hell the underscore business is. But screw it. C++ eats shit too for this. Sure, maybe Java babies you by giving you the exact error and position that the error took place at. But at least that way you don't waste hours of your life chasing invisible bugs 😠😠
I'm going to eat some food... Too much energy was consumed fighting the system... Then I'll get back to OpenCL because 😇 but that doesn't make it less bs.1 -
Had to extend the platform of a customer. For one part of my task (generating an encrypted string) there already was a class with encryption and decryption methods. This class is used in a gazillion places all over the code, so I thought it might be a good idea to re-use already existing stuff... Until I saw that the encryption method using basic Java methods (all fine with that) wrapped in a try-catch block, 'cause the Java methods may throw, returning err.getMessage() in the catch block...
Yeah...sure...makes sense... Instead of throwing an error or returning null just remove the possibility to handle the error.
So I decided to basically copy the methods and return null so I can work with that.
Created a merge request and was told by another dev of that company to remove my own impelemtation of the encryption method and use the already existing. Arguing that I won't have a possibility to prevent my code, that returns an URI containing the encrypted string, from generating something like "http://..../Encryption failed because of null" without success.
So I had to use the already existing crappy code...5 -

I feel like writing or telling people about the time I jumped from Windows 7 Ultimate and jumping to Windows 10. (I'm not against 10, but I'm never updating after what had happened to me)
It all starts when none of my games will play due to a possible issue with my graphics card. I look up "3D source game bug" and not many results pop up. I go on Microsoft's Qna areas and ask this question but to my surprise nothing they say would make sense. "Clean the pins of your graphics card, make sure you verify the games on Steam". I verified the games and they checked out as perfectly fine. I don't have access to my graphics card because this is a laptop, sadly not a tower.
Two months pass and my computer is already showing signs of stress, like it didn't want to live in a sense. It was three times slower than when I was on Windows 7 and it was unallocating areas of my main hard drive where I could make virtual hard drives.
Instantly I start looking up Linux distros and find Linux Mint. 17.3 was the current version at the time. I downloaded it and burned it onto a DVD-rom and rebooted my computer. I loaded into the disc and to my surprise it seemed almost like Windows 7 apart from the Linux part. I grab my external hard drive and partition it to hold the Linux distro and leave it plugged in incase Windows 10 does actually fail.
On December 19, a few months after Windows 10 had released. I start my laptop to try and continue my studies in video game development. But to my surprise, Windows 10 had finally crashed permanently. The screen flickered blue and black, and an error box saying Loginui.exe failed to start. I look at it for a solid minute as my computer had just committed suicide in a sense.
I reboot thinking it would fix the error but it didn't. I couldn't log in anymore.
I force shutdown the laptop and turn it back on putting it into safe mode.
To my surprise loginui.exe works and I sign in. I look at my desktop, the space wallpaper I always admired, the sound files, screen shots I had saved.
I go into file explorer and grab everything out of my default hard drive Windows was installed on. Nothing but 400gb got left behind and that was mainly garbage prototypes I had made and Windows itself. I formatted my external hard drive and placed everything on it. Escaping Windows 10 with around 100GB of useful data I looked at the final shutdown button I would look at.
I click it and try to boot into normal Windows 10. But it doesn't work. It flickers and the error pops up once more.
I force it to shutdown and insert the previous Linux Mint disc I made and format the default hard drive through Linux. I was done. 10 gave me a lot of shit. Java wouldn't work, my games has a functional UI but no screen popped up except a black abyss and it wouldn't even let me try to update my graphics card, apparently my AMD Radeon 5450 was up to date at the AMD Radeon 5000's.
I installed Linux Mint and thinking the games would actually play I open steam and Launch Half-Life 2 to check if Linux would be nicer to me than Windows 10 had been.
To my surprise the game ran. The scene from Highway 17 popped on screen and the UI was fully functional. But it was playing at 10-15fps rather than the usual 60-70fps. Keep look at my drivers and see my graphics card isn't in use. I do some research and it turns out I have a Hybrid Laptop.
Intel HD Graphics and an AMD Radeon 5450 and it was using the Intel and not the AMD. Months of testing and attempts of getting the games to work at high frame rates pass and the Damn thing still functions at a low terrible fps. Finally I give up. I ask my mom for a Windows 7 disc and she says we can't afford it. A few months pass and I finally get a Windows 7 installation disc through money I've saved up. Proudly I put it into my optical disc drive and install it to my main hard drive deleting Linux completely. I announced to all my friends my computer was back in working order and I install everything I needed, Steam, Skype, Blender, and Unity as well as all my games. I test Half-Life 2 and it's running exceptionally smoothly, I test Minecraft at max settings and it's working beautifully. The computer was functioning properly once again and my life as a developer started as I modeled things and blender, learned beginners C# and learned a lot of Batch. Today the computer still runs at a great speed and I warn others of what happened to me after I installed Windows 10 to my machine if they are thinking of switching from 7 or 8 on an older machine.
Truly the damage to my data cannot be undone. But the memory of the maintenance, work, tests, all are a memory of how Windows 10 ruined me and every night before the one year anniversary of Windows 10's release, I took out the battery of my laptop and unplugged it from the a.c. power, just so Windows 10 doesn't show it's DLLs, batch scripts, vbs scripts, anything on my computer. But now, after this has happened and I have recovered, I now only have a story to tell5 -
Attempting to deploy my web application using Heroku. It throws me error code H14 so I add scale web=1 to the web dyno per their documentation. I get this console log thrown at me after attempting to deploy.
I'm starting to get pissed. I may end up just dumping this and deploying my node.js/java application straight to my Linux server.
Edit: Or better yet start learning to use this Docker thing I keep hearing about.

"hey, can you please help me out with this, it isn't working"
"What's it say?"
"I dunno, It's giving (not throwing) some exception/error" (no clear distinction between them)
Well, shit. Did NOT expect Java to do that in case of some undesirable flow in code! Stack trace, error message, what was happening when the exception (or actual error) occurred as inferred from logs... Nope.
Great! -
We had a tutorial on how to use spark/Hadoop.. part of the tutorial was the installation instructions for Ubuntu vms.
The Prof insisted we used an older version of Hadoop (v2.1.5), so naturally this required pulling older repos and older versions of java.
Naturally, some of the people in the class got some namespacing issues and garbage left from uninstalled packages.
Now, the tutorial was geared towards business/math people, not com sci. So most of the people didn't understand why apt didn't let them run certain commands (even though it very clearly just asked for them to run autoremove or autoclean, like in the "error message"). When the Prof and their "experienced TA" saw these messages, their recommendation was "make a new fresh vm".
The fuck? I heard that, run over and was like no. Just run the suggested command, it's literally a simple issue. And the guy didn't believe me. I had to sit him down, show him how I literally typed what the console was asking for, and everything just worked... The guy's response was "well that's Linux for you, its really complicated and can never trust anything, this time it worked, but next time it might not". Dude... Do you even know what you are saying? Like you are a supposed expert, least have some understanding of the package manager you are using. Maybe things will then be less "schrodinger cat".
God damn I can't wait to be out of this stupid fucking school. Never going back to academia.1 -
So I recently finished a rewrite of a website that processes donations for nonprofits. Once it was complete, I would migrate all the data from the old system to the new system. This involved iterating through every transaction in the database and making a cURL request to the new system's API. A rough calculation yielded 16 hours of migration time.
The first hour or two of the migration (where it was creating users) was fine, no issues. But once it got to the transaction part, the API server would start using more and more RAM. Eventually (30 minutes), it would start doing OOMs and the such. For a while, I just assumed the issue was a lack of RAM so I upgraded the server to 16 GB of RAM.
Running the script again, it would approach the 7 GiB mark and be maxing out all 8 CPUs. At this point, I assumed there was a memory leak somewhere and the garbage collector was doing it's best to free up anything it could find. I scanned my code time and time again, but there was no place I was storing any strong references to anything!
At this point, I just sort of gave up. Every 30 minutes, I would restart the server to fix the RAM and CPU issue. And all was fine. But then there was this one time where I tried to kill it, but I go the error: "fork failed: resource temporarily unavailable". Up until this point, I believed this was simply a lack of memory...but none of my SWAP was in use! And I had 4 GiB of cached stuff!
Now this made me really confused. So I did one search on the Internet and apparently this can be caused by many things: a lack of file descriptors or even too many threads. So I did some digging, and apparently my app was using over 31 thousands threads!!!!! WTF!
I did some more digging, and as it turns out, I never called close() on my network objects. Thus leaving ~30 new "worker" threads per iteration of the migration script. Thanks Java, if only finalize() was utilized properly.1 -
I just wanted to try out apache open natural language processing. But why is building java from source such a pain? Totaly unintuitive. 😕

Watched 2 different vendors struggle to get something going.
I stayed quiet during both meetings, the first, was a misconfiguration error on their project code. They were tailoring the product that they sold my institution, I could see the simple error: key-value settings on one of their json files (it is a dotneto app)
I don't get paid to troubleshoot the code for an external company, so I was silent, knowing full well this would take longer to get done, needless to say, I had originally advised against purchasing this product but was not listened to, very well then.
The other was a configuration issue on the side of a different Java based product, there were some strange XML configuration entries, some other project files that made little sense, but again: quiet.
Department head is concerned about the delays that this might cause and will still not ask if I am willing to help since he knows I A) was against this product purchase from the get go and B) knows DAMN well I will say that I don't get paid to troubleshoot the issues that third party vendors charging us over 100k of product "worth", they wanna spend the money on "enterprise" shit that does not work,they can deal with their own shit programs.
Morale of the story: money moves people. If there is no bling in my account: then I ain't doing it.
Now, I do get paid well for what I do, and for that I do bust my ass, for everything else: there is mastercard.11 -
gradle is infuriating.
firstly there are so limited resources to understand how it's building a java/android code. everything happens by magic and hit+trial
secondly the plugins and the tasks works in mysterious ways. sometime they work when applied in the project root's gradle file, other times they work when applied in module's gradle file, nd other times they need configuration at both levels.
then there are gradle tasks like build ,test, assemble , clean etc. these are less of an action and more of an alias to run a bundle of actions.
then we have 3rd party plugins which attach themselves to these "fat-actions" and run before/after them
and finally we have the fuckup from the java world where the only available code coverage plugin is jacoco and IT FUCKING SUCKS!!! it is a test environment plugin, it should impact test tasks , but somehow it's fucking with the assemble taskin such a manner, that the jars ans aar files generated via plugin are giving runtime errrors. yes , runtime! as if we are back in the messed up js world of "everything is good unless running live"
even if it was a compile time eeror, i would have considered. but runtime?!! fucking runtime error?! i barely understand this shit, there is absolutely no info available as to which classes are being used to create a build and how, and i am supposed to fix this? wtf?!4 -
Today is thursday. Oh no.
At thursdays I have a 8h30-19 schedule (I have 1h30' of free time to go home and cry after I finish a class at 15h30 though) and there's this one class I DREAD. It's a 2h class at 17h and it's an exercise class. This wouldn't be so bad it I actually understood the code behind the exercises, because they don't teach us code in the theory classes (btw it's C. I hate that language because of all this). The teacher pretty much tells us "do this exercise", waits like 10' and then starts to (try to) explain what we're supposed to do. Oh my god.
The other day he was like "write "exec ( ... "text" ... )", compile and execute". It didn't work. Of course it didn't why would it? I was switching around between terminal, manual and text editor, to no avail. In the end he explained but I don't think I got it.
Every time I think about this class I die a little inside and start to become somewhat anxious to be honest. The theory is not that that hard, the practice part is what is killing me (I have test in 2w but I'm just gonna start studying earlier so I can go watch this match LoL).
Does someone know a good book (preferably online, if possible) or a good website on C? I really need to read that, that language is killing me.
Bonus: the other day I had to do a homework that was to be delivered. We had to write a program that read the program and its arguments like this:
./program_name
numArgs
arg1
arg2
etc
I wrote the code, had some bumps in the way, asked a colleague for help because we needed to have a custom function made that was to be done in the class but that I couldn't make because of the reasons above. Then it came the time to test. My VM broke (I think I'm gonna format my PC to try to fix that. Have installed some other versions of the VM but the installations fails or the machine doesn't start) so I sent it to said colleague to test. She said it did OK and so I sent the work to this website we have to send our works to.
"2 errors".
What? What happened? She said it worked just fine.
Looked at my code, couldn't see anything wrong.
Asked the same colleague for help.
Turns out I missed a space. A SPACE. I don't think I've ever felt so frustrated in my life. A presentation error in Java is a good thing, at least we know the program works fine, it's just the output that's wrongly formatted. But C? Nope, errors all around, oh my god. I'm still mad about it.
And I owe her a chocolate.1 -
My DEV Story
After reading it, make a favor by ++d
Thought to be a software engineer in future
Learnt Python's basic modules, AI, and some ML
After getting intermediate in python, I started learning Java as my second language but could not do it because of JDK 8. Now don't ask me why.
Then, just stepped into game development with unity and C#, having a basic knowledge of C# with no experience in making a game myself. This is called ignorant.
After getting no success, I started learning PHP and got the chance to make a website having no content ;)
But it cannot meet my requirements
Soon I got content that AdSense regards as no content, no problem
I started learning Flask, a module in python for making web applications.
It took me 1 month to complete my website, which can convert file formats.
The idea for deploying it to the server
Sign Up to DigitalOcean
Domain Name from GoDaddy (I know NameCheap is better but got some offer from it)
Made a VPS for what I have to pay $5/month
Deploy my Flask App using WSGI server
This is the worst dev experience
.
.
.
.
Why in all the tutorial, they only deploy a flask app which displays Hello World only and not anything else
WSGI or UWSGI Server does not give us permission to save any file or make any directory in it
Every time........ERROR
Totally Fucked Up
Finally, it works on localhost with port 80
I know this is not the professional way to host a website but this option was only left.
What can I do
Now, I cannot issue a free SSL certificate through Let's Encrypt because **Error 98 Address Already In Used**
The address was port 80 on which my Flask App was running

Just spent 30+ hrs on an error that was due to using flatMap instead of map.
I feel stupid!
Pro Tip: Never try to learn Spring without learning java properly. -
I'm studying atm and I survived Haskell, SKI, ... now, in the second semester we started with Python (yeay ♡) and Java (that's fine).
One of the first exercises is about installing Jython ('cause it's good, right? /sarcasm off), using the lecturer's module and write some code for it. It's about painting some shitty graphics *gasp*...
I use PyCharm (not really necessary for these crappy exercises) and programming on Windows and/or Linux.
Downloaded Jython, installed it, set it as interpreter - works fine (win10, pycharm).
Some students got weird errors using linux - for me it's the same but meh Idc.
Today I tried using Jython on my notebook, too (win10, pycharm). Downloaded it from the Jython Project website. Can't update pip, can't run modules - error is about fckin charsets...
Some other student figured out - wrong version of Jython. The newer version has some bug fixes.
2.7.1 is the one and only - the download section of their website offers 2.7.0 as latest release...
So - how to know there is a version 2.7.1?
#1 version control website = Wikipedia
So... there is a blog, guy's writing about this release - this installer is hosted at maven central. Yeay. Obvious. Thanks.
Can't describe such stupidity - maybe it's the user again 😂 -
When I wrote count++ in Python and got syntax error. Darn!!! I just applied Java and C syntax again!

My work product: Or why I learned to get twitchy around Java...
I maintain a Java based test system, that tests a raster image processor. The client is a Java swing project that contains CORBA bindings to the internal API of the raster image processor. It also has custom written UI elements and duplicated functionality that became available in later versions of Java, but because some of the third party tools we use don't work with later versions of Java for some reason, it's not possible to upgrade Java to gain things as simple as recursive directory deletion, yes the version of Java we have to use does not support something as simple as that and custom code had to be written to support it.
Because of the requirement to build the API bindings along with the client the whole application must be built with the raster image processor build chain, which is a heavily customised jam build system. So an ant task calls out to execute a jam task and jam does about 90% of the heavy lifting.
In addition to the Java code there's code for interpreting PostScript files, as these can be used to alter the behaviour of the raster image processor during testing.
As if that weren't enough, there's a beanshell interface to allow users to script the test system, but none of the users know Java well enough to feel confident writing interpreted Java scripts (and that's too close to JavaScript for my comfort). I once tried swapping this out for the Rhino JavaScript interpreter and got all the verbal support in the world but no developer time to design an API that'd work for all the departments.
The server isn't much better though. It's a tomcat based application that was written by someone who had never built a tomcat application before, or any web application for that matter and uses raw SQL strings instead of an orm, it doesn't use MVC in any way, and insane amount of functionality is dumped into the jsp files.
It too interacts with a raster image processor to create difference masks of the output, running PostScript as needed. It spawns off multiple threads and can spend days processing hundreds of gigabytes of image output (depending on the size of the tests).
We're stuck on Tomcat seven because we can't upgrade beyond Java 6, which brings a whole manner of security issues, but that eager little Java updated will break the tool chain if it gets its way.
Between these two components we have the Java RMI server (sometimes) working to help generate image data on the client side before all images are pulled across a UNC network path onto the server that processes test jobs (in PDF format), by reading into the xref table of said PDF, finding the embedded image data (for our server consumed test files are just flate encoded TIFF files wrapped around just enough PDF to make them valid) and uses a tool to create a difference mask of two images.
This tool is very error prone, it can't difference images of different sizes, colour spaces, orientations or pixel depths, but it's the best we have.
The tool is installed in both the client and server if the client can generate images it'll query from the server which ones it needs to and if it can't the server will use the tool itself.
Our shells have custom profiles for linking to a whole manner of third party tools and libraries, including a link to visual studio 2005 (more indirectly related build dependencies), the whole profile has to ensure that absolutely no operating system pollution gets into the shell, most of our apps are installed in our home directories and we have to ensure our paths are correct for every single application we add.
And... Fucking and!
Most of the tools are stored as source bundles in a version control system... Not got or mercurial, not perforce or svn, not even CVS... They use a custom built version control system that is built on top of RCS, it keeps a central database of locked files (using soft and hard locks along with write protecting the files in the file system) to ensure users can't get merge conflicts by preventing other users from writing to the files at all.
Branching is heavy weight and can take the best part of a day to create a new branch and populate the history.
Gathering the tools alone to build the Dev environment to build my project takes the best part of a week.
What should be a joy come hardware refresh year becomes a curse ("Well fuck, now I loose a week spending it setting up the Dev environment on ANOTHER machine").
Needless to say, I enjoy NOT working with Java. A lot of this isn't Javas fault, but there's a lot of things that Java (specifically the Java 6 version we're stuck on) does not make easy.
This is why I prefer to build my web apps in python or node, hell, I'd even take Lua... Just... Compiling web pages into executable Java classes, why? I mean I understand the implementation of how this happens, but why did my predecessor have to choose this? Why?2 -
Changed db host from sles 11 to sles 12...
Users had to set a new pw...
And there is this guy, who is longer in this business,than i am on this world...
Yet i had to show him passwd...
And now he gets back to me with the following:
C: "since the pw reset my password doesn't work"
> Cutout from the error message, which clearly says ssh algorithm negotiation failed
Me: "just to be sure, are your pws set correctly? And what client do you have, where does this message come from?"
C:"i checked the pws, they match. I still get the error."
...
Me: "... And whats your client? Does putty/cygwin still work"
C:"yeah they still work"
...
Me:"and what throws this error?"
C:"uhm Ant"
*Fyi: some version as old as the brown coals used to do some shady db2 and java stuff"
*Me doin a quick googleing for the error and Ant"
Me:"yup... It appears, that the java lib has some problems with the ssh algorithms.. here are some stackoverflow links, which described your problem." *at least make me try, please*
*Waiting for his response, which will surely result in pure enlightenment and bliss for me...*
Seriously... How dares java to fuck this up... -
TLDR: A friend had only a local repository and fucked it up completly
A friend of mine had to do an project for school. Sche decided to do a little chat application. The requirements were to use java in combination of javafx.
Things started very well. Sometimes she asked me for a little help but that was no problem. She used mercurial for version control which was an inportant requirement too. But. The teacher didn't teach them how to use mercurial so all she had was a local repository. A few days ago she called me and told me that she fucked up the repository. I told her she should cerp calm and wait until i am at home. It's a fucking repository. this can be fixed i thought. But when i arrived at home and she sent me the repo i tried everything but a file (stored at .hg/store/) was missing. it was a manifest file. I asked her what happened to this file. "I deleted it because there were error messages because of it" FML. Why would you even delete such a file?
Luckily for her she sent me a copy of her repo to look at it a few days ago. so she only lost 5 commits.1 -
I'm very sad.
I don't pretend to work on the next Facebook, Google search engine or something else.
I would to be part of something useful.
But i work in a shitty company where quality, architecture planning and TDD are underrated.
Only to build very simple webapplications, where things you take for granted like server side input or a simple error page without java stacktrace are missing or not planned properly.
We have functional analysts, but worst specs ever.
I hate all of this... -
So at the HS I go to, there are 4~5 programmers (only 3 real "experienced" ones though including me).
So coming from JS & Python, I hate Java (especially for robotics) and prefer C++ (through some basic tutorials).
Programmer Nº2 is great at everything, loves Objective-C, Swift, Python, and to a certain extent Java.
Programmer Nº3 loves Python and used to do lots of C#, dislikes Java and appreciates Go (not much experience).
So naturally I get shit on (playfully) because of my JS background, because they don't understand many aspects of it. They hate the DOM manipulation (which is dislike too tbh), but especially OOP in JS, string/int manipulation, certain methods and HOISTING.
So, IDK if Java or C++ (super limited in them) have hoisting, but if you don't know what hoisting is, it means that you can define a variable, use it before assigning a value, and the code will still run. It also means that you can use a variable before defining it and assigning a value to it.
So in JS you can define a variable, assign no value to it, use it in a function for instance, and then assign a value after calling the function, like so:
var y;
function hi(x) {
console.log(y + " " + x);
y = "hi";
}
hi("bob");
output: undefined bob
And, as said before, you can use a variable before defining it - without causing any errors.
Since I can barely express myself, here is an example:
JS code:
function hi(x) {
console.log(y + " " + x);
var y = "hi";
}
hi("bob");
output: undefined bob
So my friends are like: WTF?? Doesn't that produce an Error of some sort?
- Well no kiddo, it might not make sense to you, and you can trash talk JS and its architecture all you want, but this somehow, sometimes IS useful.
No real point/punchline to this story, but it makes me laugh (internally), and since I really want to say it and my family is shit with computers, I posted it here.
I know many of you hate JS BTW, so I'm prepared to get trashed/downvoted back to the Earth's crust like a StackOverflow question.6 -

Went for the iv as senior java developer, they ask me to answer 3 pages of coding question, i need to read the code and state my answer. What's worse is, their coding without main method, and asking do this coding can be execute without error or not? What is the answer for this question.
I read all the questions and all written question without main method 🤣🤣.
Not sure are they really stupid or just testing me tho. But I still state my answer, "executing with error message.."
Later than, the manager did not show up to interview me and others 3 candidate.
Thats really funny. They ask us to leave and for their feedback.
After few month, meet my ex-colleague where he just resign from the that company. Surprisingly I told him about the test, than he inform the company to update the test 🤣🤣🤣.
Lucky me, if i choose to work there its gonna be a lot of hell.
fyi, my friend work as SCM, Software Configuration Manager which he always make a joke about his position as The Manager 🤣. I fucking believe it for month when we first work with same company. Just realized when he need to configure my machine to config as company rule. Dammit dude -
Android Crash is Fucking Bullshit Ever on this Earth Planet.
I really Hate these Number of Versions and Bullshit Incompatibility between each one.
It is Just a Shit Developed on Java.
The Crash Really Fucks the eyes of Developer.
And Fucking Bullshit Errors are not Even visible, Sometimes the shit goes so worst that it does'nt even give the Line Number where error Exists.
Worst OS Developed for Mobile on This Planet.
Anyone getting into these development i suggest IONIC is Best to start instead of Coding Native Bullshit Android.
If anyone knows how to see the realtime errors besides Logcat and Firebase Error please let me know.

My path into development started with my dad. He was a COBOL programmer and would bring his work home to debug by hand. He would explain his thinking and programming concepts as he went through his code.
I then got into Basic, and Visual Basic 6.0 (right before .NET). In high school CS I and CS II consisted of VB.NET and Java, but it also solidified some foundational concepts I was missing; binary, hex, flow charts, etc.
After that though, everything else was self exploration and trial and error. It all came together. I love my path, and it brought me here to devRant via the programming friends I have made along the way. -
I give up! Been trying to solve this shit for a week and still failed:

Hi, so currently in my Java course, I'm learning about abstract classes. I noticed how a method in an abstract class can use an access modifier, however, interfaces don't use them.
In addition to this, I noticed that IntelliJ didn't give me an error stating that adding an access modifier was redundant or useless. So I wanted to know if there is a point in adding access modifiers to abstract methods.
Thanks so much for anyone who can help me out with this!1 -

And there I was thinking Maven is going to make life simpler, with this granular dependency management and IDE independence (no extraneous classpath and module management required). But wait, it turns out that to run simple Ant task I need all my dependencies to have *.pom. Every. Fricking. Dependency.
I mean, sure, only if I knew which sub-dependencies they all had, but that seems like heck a lot of work to make external JAR libraries to work with Maven process.
WHY TODAY? Yesterday I had no issue: uploaded few libraries in corporate repository, refreshed index, dependencies downloaded, even had time appending javadoc to one of them and it worked. But today is the day, right? I just run simple task with maven-antrun-plugin (mvn antrun:run@<executionID>), and it starts scanning each dependency for *.pom file. I DON'T WANT THIS. Google, help me. Oh, no direct answers and clues?
Just... fuck you, Maven. With all 2 days effort I could just litter in IDE's classpath, write build.xml in no time, make normal webservice, but that would require me to also litter sources with required libraries. FML!4 -
Was using an open source piece of software for data storage and visualisation to work with the loggers my company makes. When importing old data for historical views, some of the csv imports would fail without any specific error messages.
It took me a couple of hours but after looking at their csv parser and making my own little one to test with, I eventually found out that it was all down to the way datatime (I think it was?) in java deals with DST, which apparently was to just fuck shit up.
Anyhow, a few simple lines added into the parser later and it all works just fine.
Was super proud of that one as it was the first time I actually looked somewhat good in front of my senior dev. -
I "programmed" (or better changed code) long before I even knew this is programming. I basically changed levels in gorillas and nibbles back then during my DOS time thru trial and error by looking and guessing what was written there in the BASIC files. I basically used goto alot 😂.
Later I copied code listings from computer magazines that never worked but took days to type down. My first real programming experience where I bought a much to expensive book and went through it front to back was Java 1.1 or 1.2 ( don't know exactly anymore but it was no later than 1.2) and I learned it because there was this guy that told me about it and I wanted to find out what he was talking about. -
How to write programs on Android 10 that work with files/directories? Have used a number of JVM-based languages like Groovy, Clojure and Kotlin.
My last try was with Groovy. I ran it under Dcoder which has to be cloud-, based as it supports numerous languages. I gave it permission to access storage but got a file not found error from Java. Copied this excerpt for the file path.
import java.io.File
class Example {
static void main(String[] args) {
new File("/storage/emulated/0/read_file.grvy").eachLine {
line -> println "line : $line";
}
}
}
Do I need root? Do I need to change file permissions using Termux? Why can't I find a way to write simple software on a Motorola Super, 3 GB RAM and 8 cores? I hate using a phone for a computer but a seizure has me in a nursing home with only one usable hand.
Any help is greatly appreciated.5 -

Today I got a long term contract at the company I have been working at for the past two years. We maintain and develop an open source java based framework, basically you write XML to configure components (pipes, receivers, senders) in Java to build a pipeline which usually functions as a backend service. We also do implementations of the framework for our customers.
Im in a position where I my main task is applying the framework which is writing XML or skyping people at the client office to chase them to fix their server settings, please create a database for us (each time different, sometimes we get a manager user sometimes the regular user can do everytbing), create NPA's, execute queries in ACC environment or ask them why 5/10 we get an error 407 pro,y authentication required ffs
My salary is increased aswell and they told me before that I am one of the five developers in the company (20~ devs) that they want to keep costing what it costs. Management also told me they are looking to bring out something like shares or certificates for those five dev's!
Sounds pretty good right? Actually im really happy about those things but I feel like management managed to keep me in the company whilst my dreams are saying to travel around the globe, do projects wherever I am and if I find a nice place to live ill stay there.
What would you guys do?
Would you try and find a way to chase your dreams and travel/live around the globe or invest your time and effort in growing the company?1 -
Thought I'd give kotlin spring boot a shot. I assumed it would work out of the box like with java. It didn't. Apparently with jdk 17 I chose an incompatible version with the gradle version provided. Downgrade gradle. 'runApplication()' still marked with an error, which I cannot seem to solve. Answers from the internet are no solution.
But I can run the project ... but I cannot reach my dummy address, same with maven ... wtf, which part of rtfm did I miss? Wasn't kotlin supposed to be the better java?3 -

I love linux because i dont have to forced to do frickin update like windows did.
Because i have an experience after update linux mint i cant even start the main GUI program. After boot only show blank console. It seem linux update broke the compatibility between my graphics card.
At least now i dont have to update because thats an option. The output of update is not different than windows.there is a chance you broke your OS.
But the struggle is when i need to install new app in linux. Sometimes need more than hour to find out why it doesnt work from the first time.
Any help here?
So this start from the office. In the office i usually use low spec laptop that work slowly. Then i found this IDE called rapidclipse. Its very promising with GUI builder and can build cross platform mobile app using only java built on top vaadin framework.
When i use it on low spec laptop hackintosh at office it work well although it take more time than other kind of eclipse and i dont need to install any kind of app again, just download-install-create new project-run on tomcat-work well.
Then i go to home to try this new tool , IMO my low spec PC still have more power to run something than old hackintosh. Because usually i use android studio with no problem. In the old hackintosh it went too long to build gradle only.
Then i install rapidclipse, then run desktop shortcut. Then it said i need to install correct java to use correct JavaFX.
After search on SO they said i must install jdk from oracle.
Ok so i got openjdk in my linux.wtf what is the different idk but dont have time to find out.
I install jdk from oracle.
Than finally can open the rapidclipse.
Wow , this gonna be fun.
Then create new project. Just a new project.
So im waiting. I see the progress at 10%. But still no increment on that.
I switch to other app for several minutes.
Then when switched back th app still at 10% and now is at no responding state. So i force close.
After that open rapidclipse again.
The previous new project can be opened. Yay, i think.
But so many error there. Omg.
So i create new project again.
But, but, i just repeated the first error then close again then try it again for several time. But still same output.
After an hour, i give up.
But still, why , just why it work like this. No error or whatsoever.
Back later i have a problem like this on different app.
Idkwhy.1 -
Brain fart.
In Java and many other languages there are basic types, like char and String. So why does Java have char and String, but not a digit type?
A number is basically a series of digits. For modular arithmetic it is very useful to be able to extract the 3 in the number 1234, it's just the 3rd digit in a number.
Base 2, base 10, base anything could be supported easily too. E.g. a base 2 digit would be:
digit d = 0b2; // or 1b2, but 2b2 would be a compilation error
A number would then be some kind of string of digits.
Any thoughts on this?9 -
I have a Java project at work that now has some library that's using some other library that has a security issue. We have a scan during the TeamCity build that detects it but error message contains the exact library with the issue. But not the one that defined in the pom. So I can't tell from the error which pom dependency needs to be replaced.
Is there a way to get the full dependency tree? -

Won't connect anymore now.

Seems like spring boot kotlin doesn't want to cooperate in any way. Tried to set up a backend with it, but it keeps showing an error regarding wrong jvm-target. The project runs nevertheless. I changed the maven settings according to the docs, but no change. Whatever, still runs. However a newly created "hello world" rest endpoint just doesn't work, even following a beginner tutorial. localhost:8080/hello ... error fallback page.
I really wanted to give kotlin a try. Doing the same with java, instantly working.
Fuck spring boot kotlin. Or fuck me for not knowing how to handle it.5 -
