Search - "abstraction hell"
-
I’m surrounded by idiots.
I’m continually reminded of that fact, but today I found something that really drives that point home.
Gather ‘round, everybody, it’s story time!
While working on a slow query ticket, I perused the code, finding several causes, and decided to run git blame on the files to see what dummy authored the mental diarrhea currently befouling my screen. As it turns out, the entire feature was written by mister legendary Apple golden boy “Finder’s Keeper” dev himself.
To give you the full scope of this mess, let me start at the frontend and work my way backward.
He wrote a javascript method that tracks whatever row was/is under the mouse in a table and dynamically removes/adds a “.row_selected” class on it. At least the js uses events (jQuery…) instead of a `setTimeout()` so it could be worse. But still, has he never heard of :hover? The function literally does nothing else, and the `selectedRow` var he stores the element reference in isn’t used elsewhere.
This function allows the user to better see the rows in the API Calls table, for which there is a also search feature — the very thing I’m tasked with fixing.
It’s worth noting that above the search feature are two inputs for a date range, with some helpful links like “last week” and “last month” … and “All”. It’s also worth noting that this table is for displaying search results of all the API requests and their responses for a given merchant… this table is enormous.
This search field for this table queries the backend on every character the user types. There’s no debouncing, no submit event, etc., so it triggers on every keystroke. The actual request runs through a layer of abstraction to parse out and log the user-entered date range, figure out where the request came from, and to map out some column names or add additional ones. It also does some hard to follow (and amazingly not injectable) orm condition building. It’s a mess of functional ugly.
The important columns in the table this query ultimately searches are not indexed, despite it only looking for “create_order” records — the largest of twenty-some types in the table. It also uses partial text matching (again: on. every. single. keystroke.) across two varchar(255)s that only ever hold <16 chars — and of which users only ever care about one at a time. After all of this, it filters the results based on some uncommented regexes, and worst of all: instead of fetching only one page’s worth of results like you’d expect, it fetches all of them at once and then discards what isn’t included by the paginator. So not only is this a guaranteed full table scan with partial text matching for every query (over millions to hundreds of millions of records), it’s that same full table scan for every single keystroke while the user types, and all but 25 records (user-selectable) get discarded — and then requeried when the user looks at the next page of results.
What the bloody fucking hell? I’d swear this idiot is an intern, but his code does (amazingly) actually work.
No wonder this search field nearly crashed one of the servers when someone actually tried using it.
Asdfajsdfk.rant fucking moron even when taking down the server hey bob pass me all the paperclips mysql murder terrible code slow query idiot can do no wrong but he’s the golden boy idiots repeatedly murdered mysql in the face21 -
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 -
I’m trying to add digit separators to a few amount fields. There’s actually three tickets to do this in various places, and I’m working on the last of them.
I had a nightmare debugging session earlier where literally everything would 404 unless I navigated through the site in a very roundabout way. I never did figure out the cause, but I found a viable workaround. Basically: the house doesn’t exist if you use the front door, but it’s fine if you go through the garden gate, around the back, and crawl in through the side window. After hours of debugging I eventually discovered that if I unlocked the front door with a different key, everything was fine… but nobody else has this problem?
Whatever.
Onto the problem at hand!
I’m trying to add digit separators to some values. I found a way to navigate to the page in question (more difficult than it sounds), and … I don’t know what view is rendering the page. Or what controller. Or how it generates its text.
The URL is encrypted, so I get no clues there. (Which was lead dev’s solution to having scrapeable IDs instead of just, you know, fixing them). The encryption also happens in middleware, so it’s a nightmare to work through. And it’s by the lead dev, so the code is fucking atrocious.
The view… could be one of many, and I don’t even know where they are. Or what layout. Or what partials go into building it.
All of the text on the page are “resources” — think named translations that support plus nested macros. I don’t know their names, and the bits of text I can search for are used fucking everywhere. “Confirmation number” (the most unique of them) turns up 79 matches. “Fee” showed up in 8310 places before my editor gave up looking. Really.
The table displaying the data, which is what I actually care about, isn’t built in JS or markup, but is likely a resource that goes through heavy processing. It gets generated in a controller somewhere (I don’t know the resource name so I can’t find it), and passed through several layers of “dynamic form” abstraction, eventually turned into markup, and rendered as a partial template. At least, that’s how it worked in the previous ticket. I found a resource that looks right, and there’s only the one. I found the nested macros it uses for the amount and total, and added the separators there… only to find that it doesn’t work.
Fucking dead end.
And i have absolutely nothing else to go on.
Page title? “Show”
URL? /~LiolV8N8KrIgaozEgLv93s…
Text? All from macros with unknown names. Can’t really search for it without considerable effort.
Table? Doesn’t work.
Text in the table? doesn’t turn up anything new.
Legal agreement? There are multiple, used in many places, generates them dynamically via (of course) resources, and even looking through the method usages, doesn’t narrow it down very much.
Just.
What the fuck?
Why does this need to be so fucking complicated?
And what genius decided “$100000.00” doesn’t need separators? Right, the lot of them because separators aren’t used ANYWHERE but in code I authored. Like, really? This is fintech. You’d think they would be ubiquitous.
And the sheer amount of abstraction?
Stupid stupid stupid stupid stupid.11 -
This was initially a reply to a rant about politics ruining the industry. Most of it is subjective, but this is how I see the situation.
It's not gonna ruin the industry. It's gonna corrupt it completely and fatally, and it will continue developing as a toxic sticky goo of selfishness and a mandatory lack of security until it chokes itself.
Because if something can get corrupted, it will get corrupted. The only way for us as a species to make IT into a worthy industry is to screw it up countless times over the course of a hundred years until it's as stable and reliable as it can possibly be and there are as many paradigms and individually reasonable standards as there can possibly be.
Look around, see the ridiculus amount of stupid javascript frameworks, most of which is just shitcode upon vulnerabilities upon untested dependencies. Does this look to you like an uncorrupted industry?
The entire tech is rotting from the hundreds of thousands of lines of proprietary firmware and drivers through the overgrown startup scene to fucking Node.js, and how technologies created just a few decades ago are unacceptable from a security standpoint. Check your drivers and firmware if you can, I bet you can't even see the build dates of most firmware you run. You can't even know if it was built after any vulnerability regarding that specific microcontroller or whatever.
Would something like this work in chemical engineering? Hell no! This is how fucking garage meth labs work, not factories or research labs. You don't fucking sell people things without mandatory independent testing. That's how a proper industry works. Not today's IT.
Of course it's gonna go down in flames. Greed had corrupted the industry, and there's nothing to be done about it now but working as much as we can, because the faster we move the sooner we'll get stuck and the sooner we can start over on a more reasonable foundation.
Or rely on layers of abstraction and expect our code to be compilable on anything the future holds for us.2 -
I'm working with an xml schema that effectively emulates xml... inside xml...
It looks like this
<child>
<tag>ABC</tag>
<value>DEF</value>
</child>
I don't event want to get started on how it handles child elements.
This is some next level abstraction hell.
And it's not like it can't use normal XML tags. In other parts of the project it uses a slightly more sane schema.5 -
The devs delved too greedily and too deep. You know what they awoke in the darkness of abstraction hell... shadow and flame1

Why do you lil' shits keep making LAYERS and LAYERS of unnecessary abstraction and then call it goddamn progress???
Dude what the fuck is this UEFI shit?!
Why the hell do I NEED to import a frigging library and read tons of boring and overly complicated documentation just so I can paint a pixel on the screen now uh??
Alright alright yeah so the BIOS is a little basic but daaaamit son if you want something a bit more complicated you make it yourself or install an OS that provides it! Like we've been doing it for years!!!
Dude, you don't get to know what a file system is until I tell you!
The PC be like:
"You wanna dereference the 0x0 pointer? There you go: it's 0xE9DF41, anything else?
You wanna write to the screen? Ok I have a perfectly convinient interrupt setup for that.
Wanna paint a pixel yellow? Ok, just call this other interruption. Theere we go.
And it only took four bytes and a nanosecond to do it."
That shit works, and if you want something more complex, but not too much, that still runs efficiently install DOS.
Don't mess around with the hardware pleeease.
We can still understand what's going on down there. Once UEFI steps in, it'll be like sealing a door forever. Long live BIOS damn it all!1 -
Sydochen has posted a rant where he is nt really sure why people hate Java, and I decided to publicly post my explanation of this phenomenon, please, from my point of view.
So there is this quite large domain, on which one or two academical studies are built, such as business informatics and applied system engineering which I find extremely interesting and fun, that is called, ironically, SAD. And then there are videos on youtube, by programmers who just can't settle the fuck down. Those videos I am talking about are rants about OOP in general, which, as we all know, is a huge part of studies in the aforementioned domain. What these people are even talking about?
Absolutely obvious, there is no sense in making a software in a linear pattern. Since Bikelsoft has conveniently patched consumers up with GUI based software, the core concept of which is EDP (event driven programming or alternatively, at least OS events queue-ing), the completely functional, linear approach in such environment does not make much sense in terms of the maintainability of the software. Uhm, raise your hand if you ever tried to linearly build a complex GUI system in a single function call on GTK, which does allow you to disregard any responsibility separation pattern of SAD, such as long loved MVC...
Additionally, OOP is mandatory in business because it does allow us to mount abstraction levels and encapsulate actual dataflow behind them, which, of course, lowers the costs of the development.
What happy programmers are talking about usually is the complexity of the task of doing the OOP right in the sense of an overflow of straight composition classes (that do nothing but forward data from lower to upper abstraction levels and vice versa) and the situation of responsibility chain break (this is when a class from lower level directly!! notifies a class of a higher level about something ignoring the fact that there is a chain of other classes between them). And that's it. These guys also do vouch for functional programming, and it's a completely different argument, and there is no reason not to do it in algorithmical, implementational part of the project, of course, but yeah...
So where does Java kick in you think?
Well, guess what language popularized programming in general and OOP in particular. Java is doing a lot of things in a modern way. Of course, if it's 1995 outside *lenny face*. Yeah, fuck AOT, fuck memory management responsibility, all to the maximum towards solving the real applicative tasks.
Have you ever tried to learn to apply Text Watchers in Android with Java? Then you know about inline overloading and inline abstract class implementation. This is not right. This reduces readability and reusability.
Have you ever used Volley on Android? Newbies to Android programming surely should have. Quite verbose boilerplate in google docs, huh?
Have you seen intents? The Android API is, little said, messy with all the support libs and Context class ancestors. Remember how many times the language has helped you to properly orient in all of this hierarchy, when overloading method declaration requires you to use 2 lines instead of 1. Too verbose, too hesitant, distracting - that's what the lang and the api is. Fucking toString() is hilarious. Reference comparison is unintuitive. Obviously poor practices are not banned. Ancient tools. Import hell. Slow evolution.
C# has ripped Java off like an utter cunt, yet it's a piece of cake to maintain a solid patternization and structure, and keep your code clean and readable. Yet, Cs6 already was okay featuring optionally nullable fields and safe optional dereferencing, while we get finally get lambda expressions in J8, in 20-fucking-14.
Java did good back then, but when we joke about dumb indian developers, they are coding it in Java. So yeah.
To sum up, it's easy to make code unreadable with Java, and Java is a tool with which developers usually disregard the patterns of SAD. -
i always get sucked into this "cute code" hell whenever i am working with a b2c codebase, and especially with kotlin code.
here's a scenario:
task : build a debounce logic for an input view where each user input is currently triggerring an api call.
my steps
1. read what debouncing is.
2. see if any code is available on the internet
=> found a code piece on the internet with some level of abstraction ( basically a simple final class that implements the input event callback and encapsulates the debounce logic)
3) copy it, run it , it wokrs
------
for any sane coder, these steps are hardly 10-30 mins and they can move on with life. but its your truly that made this task into a 6hour research only to come up at similar solution. my curiosity led me to stupid places
1) why this class is final? what if someone else wanna use it but with a different behaviour? lets try open(non final class) .
2) why even use a class? it extends an interface, lets try to wrap the logic in interface itself (kotlin supports interfaces that don't require implementation)
3) umm , the interface works but it looks ugly, with all its global overridden variables. what about we make it extension?
4) yeah the extension approach is also not very good, lets go back to open class.
5) but extend is super nice to look! lets keep the extension and open class too
6) can we optimise the implementation? why it uses an additional handler? what if we provided everything in constructor? how about builder pattern?
FUCK MY BRAIN! there are so much fucking options that i forgot that i spent 4 hours on this small thing
the simplest approach would have been tk just shove all the listeners and everything in activity and forget about it :/
senior devs on this platform, how do you stop yourself from adding every concept that you know into the smallest possible task?6
