I spent an hour arguing with the CTO, pushing for having all our new products' data in the database (wow) with an API I could hit to fetch said data (wow) prior to displaying it on our order page.
He never actually agreed with me, but he finally acquiesced and wrote the migrations, API, and entered my (rather contrived) placeholder data. (I've been waiting on the boss for details and copy for three days.)
Anyway, it's now live on QA. but. I don't know where QA is for this app, and it's been long enough that i'm kind of afraid to ask.
Does that sound strange?
well.
We have seven (nine?) live applications (three of which share a database), and none of their repos match their URLs, nor even their Heroku app names. (In some of these Heroku names, "db" is short for the app's namesake, while in the rest it's short for "database").
So, I honestly have no idea where "dbappdev" points to, and I don't have access to the DNS records to check. -.-
What's more: I opened "dbappdev" on Heroku and tested out his new API -- lo and behold! it returns nada. Not a single byte. (Given his history I expected a 500, so this is an improvement, I think. Still totally useless, however.)
And furthermore: he didn't push the code to github, so I cannot test (or fix) it locally.
just. UGH.
every day with this guy, i swear.16 -
So, a rather unfortunate bug on the Minecraft website.
Minecraft allows you to change your name every 30 days. I was reverse engineering their API so I could use it personally.
On the username change form there are two fields: your desired username, and your password.
To protect myself from actually changing my name, I purposefully put in password123 so that it would fail. Then, I clicked "Change name" to monitor the network traffic.
Well that's when two unfortunate things combined.
#1: I used my last name to test. It's a unique word that is relatively short and very easy for me to type out of habit.
#2: That password field doesn't actually get validated.
So imagine my shock when I clicked "change username" and it WORKED.
And now my username is doxxing me for at least 30 days + the permanent name history
FUCK me6 -
Preface: i'm pretty... definitely wasted. rum is amazing.
anyway, I spent today fighting with ActionCable. but as per usu, here's the rant's backstory:
I spent two or three days fighting with ActionCable a few weeks ago. idr how long because I had a 102*f fever at the time, but I managed to write a chat client frontend in React that hooked up to API Guy's copypasta backend. (He literally just copy/pasted it from a chat app tutorial. gg). My code wasn't great, but it did most of what it needed to do. It set up a websocket, had listeners for the various events, connected to the ActionCable server and channel, and wrote out updates to the DOM as they came in. It worked pretty well.
Back to the present!
I spent today trying to get the rest to work, which basically amounted to just fetching historical messages from the server. Turns out that's actually really hard to do, especially when THE FKING OFFICIAL DOCUMENTATION'S EXAMPLES ARE WRONG! Seriously, that crap has scoping and (coffeescript) syntax errors; it doesn't even run. but I didn't know that until the end, because seriously, who posts broken code on official docs? ugh! I spent five hours torturing my code in an effort to get it to work (plus however many more back when I had a fever), only to discover that the examples themselves are broken. No wonder I never got it working!
So, I rooted around for more tutorials or blogs or anything else with functional sample code. Basically every example out there is the same goddamn chat app tutorial with their own commentary. Remember that copy/paste? yeah, that's the one. Still pissed off about that. Also: that tutorial doesn't fetch history, or do anything other than the most basic functionality that I had already written. Totally useless to me.
After quite a bit of searching, the only semi-decent resource I was able to find was a blog from 2015 that's entirely written in Japanese. No, I can't read more than a handful of words, but I've been using it as a reference because its code is seriously more helpful than what's on official Rails docs. -_-
Still never got it to work, though. but after those five futile hours of fighting with the same crap, I sort of gave up and did something else.
zzz.
Anyway.
The moral of the story is that if you publish broken code examples beacuse you didn't even fking bother to test them first, some extremely pissed off and vindictive and fashionable developer will totally waterboard the hell out of you for the cumulative total of her wasted development time because screw you and your goddamn laziness.8 -
I'm extremely lucky I'm not violent person. What happened today for some reason just completely pissed me off. I'm not sure why it got under my skin so much, but I feel completely disrespected.
I went to our marketing person's office to discuss a basic requirement for our api. Very simply, we have a lot of old shitty date that doesn't have a lot of fields filled out (worse yet, some are simply bogus values like crazy random dates and whatnot).
She put in a ticket claiming our most recent change started changed the creation dates to be empty. Easy enough to disprove, because the marketing software we have shows a records of all the edits for each contact, and if it came from our api it'll be labeled as "Web API". So of course I check the example contacts she give us, and there's no history of changes, meaning they never had the date to begin with (which is correct, as until now we didn't track creation date WHICH IS NOT MY DECISION. So dude 10 years ago probably made that decision).
So I start asking what exactly we're using it for. She does an absolutely horrible job of describing it and keeps telling me "no you absolutely have to be able to do all this, it's our requirements". By "this" she wants me to magically give all these contacts correct creation dates after the fact.
Eventually she gets the whole campaign idea out and I point, politely, that they're probably violating GDPR. She starts yelling saying her and her boss have been doing marketing for years and they know what they're doing. So I (less politely this time) said that's fine, I just want to talk with her boss to make sure he understands he's in the grey area and that if I'm the one building this, I'm kind of liable as well.
She clearly didn't like that, but I thought whatever, let's just agree on some requirements and I'll pass it on to my boss (who genuinely shits on her every single day and is constantly saying she never knows what she's doing).
So I go back , do some work. A little later I have to go print something off which is next to her office. Her door is shut, but I can hear her from down the hall yelling at someone about the conversation we just had. She actually starts mocking me. Doing the "stupid person" voice. This goes on for longer than our conversation.
Like I said, I know I'm right and she's just venting because she doesn't want to admit she's made a mistake. But for some reason it just completely broke me. I'm new but up until this point everyone had been pretty open about how they feel about me and my co-worker. But she just didn't need to go that bloody far.9 -
I’m adding some fucking commas.
It should be trivial, right?
They’re fucking commas. Displayed on a fucking webpage. So fucking hard.
What the fuck is this even? Specifically, what fucking looney morons can write something so fucking complicated it requires following the code path through ten fucking files to see where something gets fucking defined!?
There are seriously so fucking many layers of abstraction that I can’t even tell where the bloody fucking amount transforms from a currency into a string. I’m digging so deep in the codebase now that any change here will break countless other areas. There’s no excuse for this shit.
I have two options:
A) I convert the resulting magically conjured string into a currency again (and of course lose the actual currency, e.g. usd, peso, etc.), or
B) Refactor the code to actually pass around the currency like it’s fucking intended to be, and convert to a string only when displaying. Like it’s fucking intended to be.
Impossible decision here.
If I pick (A) I get yelled at because it’s bloody wrong. “it’s already for display” they’ll say. Except it isn’t. And on top of that, the “legendary” devs who wrote this monstrosity just assumed the currency will always be in USD. If I’m the last person to touch this, I take the blame. Doesn’t matter that “legendary Mr. Apple dev” wrote it this way. (How do I know? It’s not the first time this shit has happened.) So invariably it’ll be up to me to fix anyway.
But if I pick (B) and fix it now, I’ll get yelled at for refactoring their wonderful code, for making this into too big of a problem (again), and for taking on something that’s “just too much for me.” Assholes. My après Taco Bell bathroom experiences look and smell better than this codebase. But seriously, only those two “legendary” devs get to do any real refactoring or make any architecture decisions — despite many of them being horribly flawed. No one else is even close to qualified… and “qualified” apparently means circle jerking it in Silicon Valley with the other better-than-everyone snobs, bragging about themselves and about one another. MojoJojo. “It was terrible, but it fucking worked! It fucking worked!” And “I can’t believe <blah> wanted to fix that thing. No way, this is a piece of history!” Go fuck yourselves.
So sorry I don’t fit in your stupid club.
Oh, and as an pointed, close-at-hand example of their wonderful code? This API call I’m adding commas to (it’s only used by the frontend) uses a json instance variable to store the total, errors, displayed versions of fees/charges (yes they differ because of course they do), etc. … except that variable isn’t even defined anywhere in the class. It’s defined three. fucking. abstraction. layers. in. THREE! AND. That wonderful piece of smelly garbage they’re so proud of can situationally modify all of the other related instance variables like the various charges and fees, so I can’t just keep the original currency around, or even expect the types to remain the same. It’s global variable hell all over again.
Such fucking wonderful code.
I fucking hate this codebase and I hate this fucking company. And I fucking. hate. them.7 -
Freelance project I was working on was deployed. Without my knowledge. At 11pm. Their in-house "tech guy" thought that the preview build i gave them was good enough for deployment. Massive bug, broke their api endpoints.
Got a call at 2 in the morning,asking for a fix. I told them how it was their fault and the App they deployed had TESTING written right on the main screen.
They promised additional payment to get me to fix it asap.
Went through the commit history (thank goodness their tech guy knew git, fuck him for committing on production though) and the crash reports.
Removed three lines. All became right with the world again. 😎2 -
While I work on my devRant client, I always end up thinking, "how would dfox do it for the backend".
Some of the functions I have include:
-fetching new rants, 250 at a time
-remembering the ones I've read and filtering those out (kinda similar to Algo)
-checking for updates from followed users and new notifications
My implementions are kinda spammy though part of it is because I need to use the existing API.
But even so, how would/does he implement these so all the users' requests don't end up bringing down the server, and efficiently store and retrieve everyone's view history?
My problems are small compared to his... How do you think and deal with problems at that scale though? -
It began when I was tasked with creating a better and more engaging experience for our new Facebook page. This was in Facebook's early days, so there were not really any "best practices". We were making it up as we went along. I decided one way would be to game-ify things, since gaming, at the time, was a Big Deal on Facebook and people were starting to use it to build customer funnels.
Grasping for low-hanging fruit, I decided a Tetris variant around our topic would be fun. I had to hire a dev because at the time I was a static HTML web developer just getting into social media management. I knew nothing about game development or how to use Facebook's API for such things.
Long story short, we got about $10,000 (FB app devs came at a premium then) into the project when I came across a very recent article about the history of Tetris games. It said that even though Tetris had once been considered for all intents to be public domain due to it being created by a Russian coder during the Cold War, it had just been acquired by an IP protection entity that was charging royalties for any variant of Tetris created from a specific date onward and paying the original developer. So, even though I thought I had been thorough in my initial permissions checking, it turned out we were gonna be in deep doo-doo with licensing fees and restrictions if we released this game to the public.
I had to call my boss and admit my error. She was FURIOUS and really gave me an ass-chewing over it. I then had to call the marketing person whose budget I'd been slaving away at wasting. She was a bit more forgiving (her budget was in the millions). Then I had to call the corporate legal department and explain what was going on. They told me to immediately pay any outstanding hours, then fire the dev but not before getting him to send me all code and assets, deleting his copy, and then, upon my receipt of those assets, deleting MY copy so that nothing of it ever existed. And I was supposed to say _nothing_ to the dev about why he was being let go, so that there would be no "trail" leading back to this fiasco. (The dev hounded me for weeks asking what he'd done wrong. It killed me that I was bound and gagged by corporate legal and couldn't tell him.)
I was in so much trouble. I was literally in tears over it. I'd never wasted that much money in my life. That incident pretty much sealed my fate as far as any trust my bosses ever put in me again (not much at all). I was a bit of a pariah in a lot of ways for the next 5 years whereas I had come onto the team as a young social media rockstar at first.
After that, and a couple of other bad scenarios that were less my fault and more due to a completely dysfunctional management and reporting structure, they eventually "transferred" me to another team. Which was really just a way of getting rid of me by sending me to a department that was already starting to outsource overseas and lay people off. It was less messy that way. I was in the first set of layoffs.
Since then, I've had a BIG fear of EVER joining a large corporation EVER again. I prefer to work for small businesses now, even if I get paid less. Much less stressful from an office politics and impact of mistakes standpoint.3 -

Discovered pro tip of my life :
Never trust your code
Achievements unlocked :
Successfully running C++ GPU accelerated offscreen rendering engine with texture loading code having faulty validation bug over a year on production for more than 1.5M daily Android active users without any issues.
History : Recently I was writing a new rendering engineering that uses our GPU pipeline engine.. and our prototype android app benchmark test always fails with black rendering frame detection assertion.
Practice:
Spend more than a month to debug a GPU pipeline system based on directed acyclic graph based rendering algorithm.
New abilities added :
Able to debug OpenGL ES code on Android using print statement placed in source code using binary search.
But why?
I was aware of the issue over a month and just ignored it thinking it's a driver bug in my android device.. but when the api was used by one of Android dev, he reported the same issue. In the same day at night 2:59AM ....
Satan came to me and told me that " ok listen man, here is what I am gonna do with you today, your new code will be going production in a week, and the renderer will give you just one black frame after random time, and after today 3AM, your code will not show GL Errors if you debug or trace. Buhahahaha ahhaha haahha..... Puffff"
And he was gone..
Thanks satan for not killing me.. I will not trust stable production code anymore enevn though every line is documented and peer reviewed. -
Give up. Share Target API is already on Android, even in garbage like Samsung Internet. Desktop native apps are already history, mobile apps are sure to follow. Led by Apple Silicon, we will add JS-specific hardware to the CPUs and conquer the world. JavaScript will be the only language, with an exception being C and Lisp.9

JavaScript has an exciting API for monitoring changes made to HTML elements. The API is called the MutationObserver API, and it was invented at the prestigious W3C—the global organization comprised of our genius software engineer overlords.
Unfortunately, the W3C has a history of occasionally forgetting to proofread new specifications before publishing them, after their large army of monkeys with typewriters have produced working draft specifications, but I'm sure those mistakes are all in the past. The MutationObserver API is receiving praise online. I'm sure it's well designed!
Let's dive in to how it all works.
The API works by calling (1) a specific function of yours any time (2) a specific kind of change is made to (3) a specific HTML element—all three configurable by you.
When a change occurs, your function is passed a collection of information about the change, known as a "record".
If you ask, that record can even include information about the state of the HTML element before the change occurred, available under the `oldValue` property. How convenient!
Oh, and one more thing. If several changes happen in a short window of time, your function may receive a whole list of records—instead of being run once for each change. You know, to save on computer resources.
Anyway, let's start using this powerful API! But wait, what's that?
The record doesn't contain the state of the HTML element when the change occurred?
No problem! That information doesn't have to be included in the record. I can just look at the element as it appears right now.
But what's this, now? I'm receiving a long list of records. I guess lots of changes happened in a short window of time, so all the records are bundled together.
So how do I know what the state was for each record?
If I look at the element as it appears right now, I can only see the end result. That won't tell me what the state was after each individual change.
I guess there's only one way to find out. For each record, I need to look at the next record and check that record's `oldValue` property.
I need to write look-ahead logic just to see the state at each record!
What kind of monkey wro—oh, right. The W3C wrote the MutationObserver API.
Just forget that I asked.3 -
Alrighty, saturday morning rant time!
I just recieved a mail from one of my not-so-much-loved colleagues.
Now Background first: I work in IT-Support. We provide services for other companies. One of those services is monitoring servers and clients for various things. I recently took over the project (was assigned to do it) and restructured everything, wrote new scripts to test more stuff, successfully tested it internally and rolled it out over the last 2 weeks.
Now one of these scripts hooks into the Windows Update API and looks at the update history. It filters for known Windows Update Agent strings (UpdateOrchestrator, AutomaticUpdates and AutomaticUpdatesWuApp in case you also want to do something like this) and then looks for installation errors over the last 24 hours and wherever there have even been any successful updates over the last one and a half months.
Back to that mail.
My colleague sent me this lovely mail about a ticket i opened about his customers servers beeing all out-of-date on updates.
"This is all wrong, everything's fine. I disabled the checks."
...
It's on bitch.
So i logged on to my work PC via TeamViewer, opened my script, connected to the customer and was ready to debug the shit out of my script, knowing i probably won't even need to.
I looked at the update history via Windows Update itself and behold: 1st April. That's almost 50 days in the past.
So the script works, go figure.
Great, so search for new Updates then.
>None found.
Hm. What could it be? Did my super special colleague forget to care about his very special totally-needs-WSUS-customer WSUS again?
Yup.
Online-Search finds a ton of new Updates.
Screenshot, write pissed mail to colleague, re-enable checks, breakfast.1 -

I'm currently between jobs and have a few rants about my previous job (naturally). In retrospect, it's somewhat therapeutic to range about the sheer brainfuckery that has taken place. Enjoy!
First, let me set the scene: legacy B2B web app made with LEMP stack and sencha ext.js 3 + 4 (don't ask) and a lot of madness. Let's call that app "Alpha".
Alpha is a self made CMS build for typical ERP stuff. Yes, a self made CMS: entities are containers, containers have types and fields and values. Like so many legacy PHP apps, it does not have a dedicated FE: the HTML is rendered on the server and then spewed out to the browser.
Easy right? Coding like it's 1999! But there was a twist: Because everything is basically a container, the HTML-templates are saved in the DB. Along with the nessary JS and the CSS. And the translation variables. Why? Because fuck you! That's why. Who needs a git history anyways.
For some reason, Alpha was kinda slow.
There was also an editor, that allowed you to modify templates (web, mail, pdf) on the fly in prod. Because templates contain repeating data (header/footer), one template could contain additional templates. Much confusion. You could change templates via migration (slow, boring) or just ctrl-c/ctrl-v that sucker (fast, much excitement).
Did I mention Alpha was slow?
On with the rant: e-mails! How do they work? Noone knows. How to send mails asynchronous in PHP? Witchcraft is the only possible answer to that riddle. Here is your enterprise™ solution:
1. create mail
2. insert mail into DB
3. WAIT UP TO 59 SECONDS FOR A FUCKING CRON TO SEND MAIL
Why? "Because that way, we can resend mails in case the network is down :)"
Same procedure for the SOAP-API (db-queue + cron). You read that right: all requests to various other systems are processed once a minute.
Alpha slow.
Alpha was only one of several systems. Imagine a bunch of monolithic php apps, interconnected via SOAP, REST and GraphQL like a godamn intergalactic orgy. Image having to debug that cluster fuck.
Let's say there is a bad request. These things happen. No biggie. Remember the db-queue? Let's try to send the bad request a second time! And a third time! Still no luck? How odd. Let's create a specific file in a specific directory: a LOCK-file. Now, "the db-queue is on hold and no request gets processed :)"
Golly gee thanks Alpha.
Anyhow, did you know that MySQL has a join limit of 61 tables?3 -
Designing with "real" data
In Interaction Design Uni i've got this assignment to design a prototype for an "Ebay for used books". A requirement is that we have use "real" Data and not lorem ipsum for our design prototype tools. Which is a fair point but....
It's about 50 book categories (crime, history, romance) we have to cover, and for every category the prof wants at least 2 Books.
I've don't have the time to type in the (meta)data for 100 books at 30 JSON properties by hand. What would be your advice?
Do you maybe know a easy to use online bookshop API? (remember I'm a tech savy designer not a dev)
Or do you know someone in a low income country who does data entry? Or any experience with hiring someone on fiverr?

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 -
Damn, history web API really sucks for SPAs that have a hierarchical navigation structure.
For example there's no built-in way to know whether the back or forwards button were clicked, only that one of them was clicked.
And if you reload the page, any state you pushed remains in the history stack. So the user might not be able to go back in your application anymore, but they can still press the browser back button and all those states you pushed will be fucking up your navigation system3 -
Hii,
I want to use HTML5 History API.
I'm using ajax to fetch whole page (Yes Whole page)
Then I'm searching a particular TAG and replace whole html code in container.
I'm feeling that I'm doing it so wrong.
Can anybody tell me best use of HTML5 History API.
This update data in page without reloading page, but I think this does not make any sense.
This is an Example of my Code, You'll get Idea:
$('body').on('click','a.ajax-nav-link',function(e) {
e.preventDefault();
//call ajax method, show data and update url via html5 history api :)
if (isHistorySupport) {
//fetch url associated with a tag
let url = $(this).attr("href");
let title = $(this).attr("data-title");
fetchPage(url);
$(".ajax-nav-link").removeClass("active");
$(this).addClass("active");
return false;
}else {
alert("Not Available");
}
});5
