Me being a good collegue teaching my friend basic C++ for upcoming exam and trying my best not tore my friend apart.
Crime scene: university's library, today, 1PM.
Me: Create a new class, just type 'class' and hit TAB
Him: I'm trying to but it pastes some code
Me: That's the point of hitting TAB.. now that we are finished, include it in your main file, the one with main entry point
Him: I have no such thing
Me: Look for main function
Him: There's none, what is it called?
Me: ...main
Him: Yeah, what is it called?
Me: ..main, the name is main
Him: I get it, but what is it called?
Me: 'MAIN' FOR GODS SAKE, THE NAME IS 'MAIN' *points towards my code*..
Him: Oh, okay, I get it now
Me: Ok, let's compile
*Error pops on his screen*
Him: You know what, I don't think you can really program.. *closes laptop and walks away*.

You know who sucks at developing APIs?
Facebook.
I mean, how are so high paid guys with so great ideas manage to come up with apis THAT shitty?
Let's have a look. They took MVC and invented flux. It was so complicated that there were so many overhyped articles that stated "Flux is just X", "Flux is just Y", and exactly when Redux comes to the stage, flux is forgotten. Nobody uses it anymore.
They took declarative cursors and created Relay, but again, Apollo GraphQL comes and relay just goes away. When i tried just to get started with relay, it seemed so complicated that i just closed the tab. I mean, i get the idea, it's simple yet brilliant, but the api...
Immutable.js. Shitload of fuck. Explain WHY should i mess with shit like getIn(path: Iterable<string | number>): any and class List<T> { push(value: T): this }? Clojurescript offers Om, the React wrapper that works about three times faster! How is it even possible? Clojure's immutable data structures! They're even opensourced as standalone library, Mori js, and api is great! Just use it! Why reinvent the wheel?
It seems like when i just need to develop a simple react app, i should configure webpack (huge fuckload of work by itself) to get hot reload, modern es and jsx to work, then add redux, redux-saga, redux-thunk, react-redux and immutable.js, and if i just want my simple component to communicate with state, i need to define a component, a container, fucking mapStateToProps and mapDispatchToProps, and that's all just for "hello world" to pop out. And make sure you didn't forget to type that this.handler = this.handler.bind(this) for every handler function. Or use ev closure fucked up hack that requires just a bit more webpack tweaks. We haven't even started to communicate to the server! Fuck!
I bet there is savage ass overengineer sitting there at facebook, and he of course knows everything about how good api should look, and he also has huge ass ego and he just allowed to ban everything that he doesn't like. And he just bans everything with good simple api because it "isn't flexible enough".
"React is heavier than preact because we offer isomorphic multiple rendering targets", oh, how hard want i to slap your face, you fuckface. You know what i offered your mom and she agreed?
They even created create-react-app, but state management is still up to you. And react-boierplate is just too complicated.
When i need web app, i type "lein new re-frame", then "lein dev", and boom, live reload server started. No config. Every action is just (dispatch) away, works from any component. State subscription? (subscribe). Isolated side-effects? (reg-fx). Organize files as you want. File size? Around 30k, maybe 60 if you use some clojure libs.
If you don't care about massive market support, just use hyperapp. It's way simpler.
Dear developers, PLEASE, don't forget about api. Take it serious, it's very important. You may even design api first, and only then implement the actual logic. That's even better.
And facebook, sincerelly,
Fuck you.17 -
Smart India Hackathon: Horrible experience
Background:- Our task was to do load forecasting for a given area. Hourly energy consumption data for past 5 years was given to us.
One government official asks the following questions:-
1. Why are you using deep learning for the project? Why are you not doing data analysis?
2. Which neural network "algorithm" you are using? He wanted to ask which model we are using, but he didn't have a single clue about Neural Networks.
3. Why are you using libraries? Why not your own code?
Here comes the biggest one,
4. Why haven't you developed your own "algorithm" (again, he meant model)? All you have done is used sone library. Where is "novelty" in your project?
I just want to say that if you don't know anything about ML/AI, then don't comment anything about it. And worst thing was, he was not ready to accept the fact that for capturing temporal dependencies where underlying probability distribution ia unknown, deep learning performs much better than traditional data analysis techniques.
After hearing his first question, second one was not a surprise for us. We were expecting something like that. For a few moments, we were speechless. Then one of us started by showing neural network architecture. But after some time, he rudely repeated the same question, "where is the algorithm". We told him every fucking thing used in the project, ranging from RMSprop optimizer to Backpropagation through time algorithm to mean squared loss error function.
Then very calmly, he asked third question, why are you using libraries? That moron wanted us to write a whole fucking optimized library. We were speechless at this question. Finally, one of us told him the "obvious" answer. We were completely demotivated. But it didnt end here. The real question was waiting. At the end, after listening to all of us, he dropped the final bomb, WHY HAVE YOU USED A NEURAL NETWORK "ALGORITHM" WHICH HAS ALREADY BEEN IMPLEMENTED? WHY DIDN'T YOU MAKE YOU OWN "ALGORITHM"? We again stated the obvious answer that it takes atleast an year or two of continuous hardwork to develop a state of art algorithm, that too when gou build it on top of some existing "algorithm". After listening to this, he left. His final response was "Try to make a new "algorithm"".
Needless to say, we were completely demotivated after this evaluation. We all had worked too hard for this. And we had ability to explain each and every part of the project intuitively and mathematically, but he was not even ready to listen.
Now, all of us are sitting aimlessly, waiting for Hackathon to end.😢😢😢😢😢25 -
So I had my exams recently and I thought I'd post some of the most hacky shit I've done there over here. One thing to keep in mind, I'm a backender so I always have to hack my way around frontend!
- Had a user level authentication library which fucked up for some reason so I literally made an array with all pages and user levels allowed so I pretty much had a hardcoded user level authentication feature/function. Hey, it worked!
- CSS. Gave every page a hight of 110 percent because that made sure that you couldn't see part of the white background under the 'background' picture. Used !important about everywhere but it worked :P.
- Completey forgot (stress, time pressure etc) to make the user ID's auto incremented. 'Fixed' that by randomly generating a user id and really hoping during every registration that that user ID did not exist in the database already. Was dirty as fuck but hey it worked!
- My 'client' insisted on using Windows server.Although I wouldn't even mind using it for once, I'd never worked with it before so that would have been fucked for me. Next to that fact, you could hear swearing from about everyone who had to use Windows server in that room, even the die hard windows users rather had linux servers. So, I just told a lot of stuff about security, stability etc and actually making half of all that shit up and my client was like 'good idea, let's go for linux server then!'. Saved myself there big time.
- CHMOD'd everything 777. It just worked that way and I was in too much time pressure to spend time on that!
- Had to use VMWare instead of VirtulBox which always fucks up for me and this time it did again. Windows 10 enjoyed corrupting the virtual network adapters after every reboot of my host so I had to re-create the whole adapter about 20 times again (and removing it again) in order to get it to work. Even the administrator had no fucking clue why that was happening.
- Used project_1.0.zip etc for version control :P.
Yup, fun times!6 -
Me: Hi Guys, theres no docs on our custom push notification / deeplinking implementation. I've tried to work backwards from a QA testing doc to add new links. Can someone tell me if this is all ok? It seems to behave a little weird.
Dev: Looks ok, but we've moved to the braze platform for sending notifications. You'll need to trigger braze notifications now. Test that it works ok with that <confluence-link>
*hour later*
Me: I've tried the debugging tool, both with my payload and one of the samples from the link. It displays on the phone, but tapping it doesn't trigger the deeplinking.
Dev: No it works, try one of these <screenshot of samples I used>
*hour later*
Me: Tried it again on the real device to make sure, as well as on develop and master. Not working with those samples or mine.
Dev: No it does. It comes in here in this library <github link to line of code>
Me: ... Nope, debugged it, it doesn't get passed the next 'if' check on the next line as its missing a key/value. The whole function does nothing.
Dev: Oh do you want to send a braze notification?
Me: ..... you told me I had too .... yes I guess.
Dev: ok for a braze notification it works different, send this <entirely different sample no where on the link>
Me: ...... but ..... this is only for braze notifications ..... why .... all the samples have deeplink url's .... but they don't ....... are you ..... FFS!!!!! !@#?!

Yo!
I went to see my mother a few days, and her TV's broken.
She told me to repair it, because "you're a programmer"
Does anybody knows a python function or a useful library that could repair TV ?5 -
OMFG!! I just discover a fucking bug in a library used by thousand of people in scientific community!! 🤩🎉
Started when my program outputting strange result. I was in a huge fight with my supervisor about one of the function from the library. My hunch was telling me that this function is the source of the problem, but he insisted that no such bugs could exist in the library that has been used by thousands of people.
I couldn't reproduce the bug so I just stayed silent at that time,
But now, I finally got the bug showing. Yeah I am gonna shove it to his face next week.✊
I will also let the people who maintain the library know.
Feels so good being able to be a contributor PR to this famous library 😎
The downside is now I can't use this function, I have to implement by own function.5 -
Started working on a pihole alternative a while ago.
I like pihole a lot but one of the features I am missing is to be able to define a list of mass surveillance related domains (Snowden leaks; PRISM program and such) and show statistics based on dns queries containing blacklisted domains, prases/words and surveillance-related domains/words (google/facebook/microsoft/apple etc).
Started working on one based on an existing (php based) dns server which is open source and slowly but surely developed something which worked.
Then, I found out that the php resolving function (dns resolving) uses the system default, which can, of course, be google's dns as well. Changing this would be ideal but while the documentation suggested that it could be done some way, it didn't work for me so I chose a library which can do it with specific dns servers (to use as external dns servers).
This library used a different way of showing the retrieved dns query results and really wasn't in for converting everything by hand so i kinda quit the project a while ago.
A few days ago I thought fuck it and started again.
Now have a working version based on the new dns resolving library and made some other good improvements.
For those who are wondering why I chose PHP for this: why the fuck not?
Happy happy happy.rant php fuck mass surveillance fuck microsoft fuck google dns server yes i love php fuck facebook dns16 -
Not a rant about anything in particular. Just a summary of some feelings stored in the hateful part of my heart.
Developing for Android: Add this third-party library to your Gradle build. Use (this) built-in Android class to make the thing work.
*Clicks link
Deprecated since API version SUCKMYDICK-7. Use (this) instead
*Clicks link
Deprecated since API version LICKMYBALLS-32. Use...
Developing for Windows: Please use (this) API call. It was literally already available before Bill Gates was born. Carbon dating has placed this item to older than the universe itself and it is likely the entry point for the big bang. It is also still the best way to accomplish (task).
Developing for Linux: "Hmm, I wonder how to use this"
> > > Some shitty mailing list in small blue monospace font tells you to reference a man page that is three versions behind but the only version available.
What? Those three sentences didn't explain it enough? Well, maybe you aren't cut out for this type of thing.
JavaScript: you know how it is.
SQL: You expect a decent-quality answer from stack overflow but you always get an outdated and hacky response and it's using syntax from Microsoft SQL. You need MySQL.
C#: A surprising number of Microsoft forum results ranking high on Google. You click on one in hopes that it will be of any sort of quality. You quickly close the tab and wonder why you ever even had hope.
Literally any REST API: Is it "query" or "q"? "UserID" or "user_id"? Oh, fuck, where's the docs again?
You thought you escaped JavaScript, but it was a trick!: Some bullshit library you downloaded to make your other library work redefined one of the global variables in the project you inherited. Now you get 347 "<x> is not a function" errors in your console. Good luck, asshole.
FontAwesome/ Material fonts/ Any icon font pack: You search "Close" for a close button icon. No results. You search "Simplified railroad crossing sign without the railroad". You get a close icon.
I think that's all of my pent up rage. Each of them were too small for an individual rant so I had to do this essay.2 -
writing library code is hard.
there are sooo many details that go into writing good libraries:
designing intuitive and powerful apis
deciding good api option defaults, disallowing or warning for illegal operations
knowing when to throw, knowing when to warn/log
handling edge cases
having good code coverage with tests that doesn't suck shit, while ensuring thry don't take a hundred years to run
making the code easy to read, to maintain, robust
and also not vulnerable, which is probably the most overlooked quality.
"too many classes, too little classes"
the functions do too much it's hard to follow them
or the functions are so well abstracted, that every function has 1 line of code, resulting in code that is even harder to understand or debug (have fun drowning in those immense stack traces)
don't forget to be disciplined about the documentation.
most of these things are
deeply affected by the ecosystem, the tools of the language you're writing this in:
like 5 years ago I hated coding in nodejs, because I didn't know about linters, and now we have tools like eslint or babel, so it's more passable now
but now dealing with webpack/babel configs and plugins can literally obliterate your asshole.
some languages don't even have a stable line by line debugger (hard pass for me)
then there's also the several phases of the project:
you first conceive the idea, the api, and try to implement it, write some md's of usage examples.
as you do that, you iterate on the api, you notice that it could better, so you redesign it. once, twice, thrice.
so at that point you're spending days, weeks on this side project, and your boss is like "what the fuck are you doing right now?"
then, you reach fuckinnnnng 0.1.0, with a "frozen" api, put it on github with a shitton of badges like the badge whore you are.
then you drop it on forums, and slack communities and irc, and what do you get?
half of the community wants to ban you for doing self promotion
the other half thinks either
a) your library api is shitty
b) has no real need for it
c) "why reinvent the wheel bruh"
that's one scenario,
the other scenario is the project starts to get traction.
people start to star it and shit.
but now you have one peoblem you didn't have before: humans.
all sorts of shit:
people treating you like shit as if they were premium users.
people posting majestically written issues with titles like "people help, me no work, here" with bodies like "HAAAAAAAAAALP".
and if you have the blessing to work in the current js ecosystem, issues like "this doesn't work with esm, unpkg, cdnjs, babel, webpack, parcel, buble, A BROWSER".
with some occasional lunatic complaining about IE 4 having a very weird, obscure bug.
not the best prospect either.3 -

Time to rant about JavaScript tutorials.
If you don't know the 'jQuery basic arithmetic' joke, Google it now. It'll make you laugh, promised.
In that manner i just remembered a JavaScript tutorial my fiancee tried to follow when she did an internship at the company i work for last year.
She was tasked to create a temperature interface for our server rack, which she wanted to do via an Arduino and a webserver aswell as an SQL database.
The Arduino part wasn't really a problem, but since she had no experience with js she very closely clinged to a chart visualisation tutorial.
All of that worked very well, but beeing the person i am i looked at the code and found something off.
The chart library had no dependencies to external libraries or any local files for any of them. Though the tutorial used a jQuery import.
So why did it use jQuery?
Well...
To load the chart initialization after the page has loaded.
So they pulled the entirety of jQuery in just to do what fucking window.addEventListener('DOMContentLoaded',function(){...}); could have done.
I wonder how many people who just want something to work did this shit. I hate it that so many tutorials do not adhere any kinds of standards, override behavior because they don't like it, even though it may have a very good reason to exist, pull entire libraries in for something vanilla <language> can do in 3 lines, etc.
Fuck.7 -
"I'm almost done, I'll just need to add tests!"
Booom! You did it, that was a nuke going off in my head.
No, you shouldn't just need to add tests. The tests should have been written from the get go! You most likely won't cover all the cases. You won't know if adding the tests will break your feature, as you had none, as you refactor your untested mess in order to make your code testable.
When reading your mess of a test case and the painful mocking process you went through, I silently cry out into the void: "Why oh why!? All of this suffering could have been avoided!"
Since most of the time, your mocking pain boils down to not understanding what your "unit" in your "unit test" should be.
So let it be said:
- If you want to build a parser for an XML file, then just write a function / class whose *only* purpose is: parse the XML file, return a value object. That's it. Nothing more, nothing less.
- If you want to build a parser for an XML file, it MUST NOT: download a zip, extract that zip, merge all those files to one big file, parse that big file, talk to some other random APIs as a side-effect, and then return a value object.
Because then you suddenly have to mock away a http service and deal with zip files in your test cases.
The http util of your programming language will most likely work. Your unzip library will most likely work. So just assume it working. There are valid use cases where you want to make sure you acutally send a request and get a response, yet I am talking unit test here only.
In the scope of a class, keep the public methods to a reasonable minimum. As for each public method you shall at least create one test case. If you ever have the feeling "I want to test that private method" replace that statement in your head with: "I should extract that functionality to a new class where that method public. I then can create a unit test case a for that." That new service then becomes a dependency in your current service. Problem solved.
Also, mocking away dependencies should a simple process. If your mocking process fills half the screen, your test setup is overly complicated and your class is doing too much.
That's why I currently dig functional programming so much. When you build pure functions without side effects, unit tests are easy to write. Yet you can apply pure functions to OOP as well (to a degree). Embrace immutability.
Sidenote:
It's really not helpful that a lot of developers don't understand the difference between unit, functional acceptance, integration testing. Then they wonder why they can't test something easily, write overly complex test cases, until someone points out to them: No, in the scope of unit tests, we don't need to test our persistance layer. We just assume that it works. We should only test our businsess logic. You know: "Assuming that I get that response from the database, I expect that to happen." You don't need a test db, make a real query against that, in order to test that. (That still is a valid thing to do. Yet not in the scope of unit tests.)rant developer unit test test testing fp oop writing tests get your shit together unit testing unit tests8 -
Last year, we had to do a big university project in randomly selected groups (5-6 students in every group).Three of the five guys were completely useless, I mean, both the other competent guy and me wrote around 20,000 lines of code each, the other ones wrote around 500 lines of code (combined).
After our first few meetings we quickly knew that we have to give them a small task which was so trivial that not even they can fuck it up. But we were wrong. Oh boy, so wrong.
They simply had to code the excel export of the data, which means they had to use two functions from a library and pass the correct data. But their solution was so bad, I lost faith in humanity and was fascinated by it at the same time.
For example, there was this simple class "Room", which had a few properties like size or number of seats and a few getter/setter etc. That was a core class and written by the other qualified guy. So how did the others fuck up the excel export? They somehow rewrote that class in German (although the other code was completely in English), implemented a function for each property that would write its value to a hardcoded cell in a hardcoded excel file.
And this was just the tip of the iceberg. Needlessly to say that I had to rewrite the whole export in the night before we had to present the project.5 -

In conclusion, NVIDIA is a fucking piece of shit that can't make their own libraries compatible with themselves, and can't be fucked to write instructions that actually work.

The new mobile app codebase i'm working with, was clearly written by someone who just read a book on generics and encapsulation.
I need to pull out 2 screens into a separate library to have it shared around. The 1 networking request used is wrapped up in a 'WebServiceFactory' and `WebServiceObjectMapper`, used by a `NetworkingManager` which exposes a generic `request` method taking in a `TopLevelResponse` type (Which has imported every model) which uses a factory method to get the real response type.
This is needed by the `Router` which takes a generic `Action` which they've subclassed for each and every use case needing server communication.
Then the networking request function is part of a chain of 4 near identical functions spread across 4 different files, each one doing a tiny bit more than the last and casting everything to a new god damn protocol, because fuck concrete types.
Its not even used in that many places, theres like 6 networking calls. Why are people so god damn fucking stupid and insist on over engineering the shit out of their apps. I'm fed the fuck up with these useless skidmarks.3 -
So, i recently joined the community and must say im suprised by the lack of toxicity so probs to you people.
Anyway. I am almost finished with my internship as a Software enginieer(kind of). As my finshing presentation i made a script (mainly in Python with asciimatics(a great library btw)) wich is displayed in the Terminal (Linux Ubuntu) and as i know the kinds of people at my school i tryed to find any way they could crash it. (Already rebound the close window function from Alt + F4 to Alt+.)
Now im wondering if you; the nice people of Dev rant could suggest ways to make it safer or rather name ways you would attempt to shut it down. (i cant disable Keyboard input since that is needed to continue in the script.)
I wish you a nice day. and thanks in advance
Yours Humbly an aspiring Dev.

Back when I was in high school I created something like a simple version of MS Paint using Turbo C where the only graphics library function I used was putPixel().

CTO: We'll use epochs for any time related fields in our services.
After service integration...
Dev from producer team: Hey the time field is showing up as 1970 and not null in your table. That seems to be a bug.
Me: Code looks fine. We are converting epochs to timestamps here. Null is taken care by the library function itself.
The same dev: Actually we are sending zero instead of null values in that time field. But we'd want the end table to treat that as null.
Me: Why can't you send null then?
The dev: Actually avro doesn't support nulls. Hence the zero.
Me: WTF??????
Manager to me: Actually you need to convert them as null. Anyways, this is not a blocker and we can live with it for now.
END OF RANT
Why can't they fucking send it as null? And when I asked about the details, that particular event type doesn't require that field. Still the manager insists on sending that field for it.23 -
It's pretty common the hear developers moan about JQuery being imported to select an element. That's fair enough and I've sighed inside about that myself before.
However, I've come across an odd one. I'm looking a JavaScript file here that's close to 600KB in size.
528KB of that file is the Loadash library (which is excellent btw). The actual site uses the "join" function (https://lodash.com/docs/4.17.4#join).
I mean seriously wtf, face palms all around.
JQuery, for all it's faults is always cited in such circumstances i.e. being used unnecessarily. However, such things are not limited to Jquery alone unfortunately.
I'm now going to do some serious optimization and cut a 600KB file to ~80KB.

List of shit my superior said and wrote in the project:
1. Prefer to write "pure" SQL statement rather than ORM to handle basic CRUD ops.
2. Mixing frontend and backend data transformation.
3. Dump validation, data transformation, DB update in one fucking single function.
4. Calculate the datetime manually instead of using library like momentjs or Carbon.
5. No version control until I requested it. Even with vcs, I still have to fucking FTP into the staging and upload file one by one because they don't use SSH (wtf you tell me you don't know basic unix command?)
6. Don't care about efficiency, just loop through thousands of record for every columns in the table. An O(n) ops becomes O(n * m)
7. 6MB for loading a fucking webpage are you kidding me?
Now you telling me you want to make it into AJAX so it'll response faster? #kthxbye2 -
That's it. I'm fucking retarded. I'm just so fucking retarded. I'm so fucking supid, it makes me wonder why do I even keep trying. I'm not sure I even have the energy in my fingers to keep typing this stupid rant.
I've been banging my head against this stupid fucking issue for A WEEK. Digging into the documentation, trying different library versions, trying to move stuff around even if it didn't make sense, trying to use different approaches because maybe I was missing something, or maybe I didn't understand some concept.
Surely spawning a child function from a parent can't be that hard, right?
Nothing.
Even tried it on a different OS - who knows, maybe it's Windows doing some if its magic fuckery?
Still nothing.
"Wait, why am I calling this function directly instead of calling its parent?"10 -
You know you have chosen the wrong JS library when you read a function definition like this:
validateSync(schema, options, callback) -
Some motherfucker pulled the entire fucking Lodash library off a CDN so he could use one fucking function.
Buddy, the library is open source, you can just copy the relevant code off Github
This is why websites are slow as fuck, devs import shit they don't need3 -
During a design meeting, our boss tells me that Vertx's MySQL drivers don't have prepared statements, and that in the past, he's used a library or his own functions to do all the escaping.
"Are you kidding me? Are you insane?"
I insisted that surely he must be wrong; that no one would release a database library without built in support for query arguments. Escaping things by hand is just asinine and a security risk. You should always use the tools in the database drivers, as new security vulnerabilities in SQL drivers can be found and fixed so long as you keep your dependencies up to date.
He told me escaping wasn't as tricky as I made it out to be, that there were some good libraries for it, and insisted Vertx didn't have any built in support for "prepared statements." He also tried to tell us that prepared statements had performance issues.
He searched specifically for "prepared statements" and I was like, "You know they don't have to be called that. They have different names in different frameworks."
Sure enough, a short search and we discovered a function in the Vertx base database classes to allow SQL queries with parameters. -
When I first started my current job, 2.5 years ago, I helped write the class that told the machine how to dispense and deposit money.
When the other programmer left, I decided to refactor that section. I wrote a new class that told the machine how to dispense and deposit money.
We are integrating new hardware that has a very different protocol of communication. I am making a library that will convert universal commands into vendor specific function calls. I am writing a new library that tells the machine how to dispense and deposit money.3 -
Not sure if it's the worst code review but it's a recent one.
We don't really do code reviews where I work unfortunately but my coworker used my framework for the first time (build some nice composer libraries for cmdline projects) and asked if I could make them do autoloading.
He never used namespaces before so I was glad to help him out.
What I saw was a dreadful mess. His project was called "scripts" so good luck picking a namespace...
Than it was all lose functions in the executable file. All those functions are however called by a class in another file (if they where not calling eachother as a cascading mess). That class was extending an abstract class from my library as instructed. However I never imagined my lib being raped like that.
The functions themselves are a horrible mess. Nothing uniform completely different style (our documentation states PSR's should be used).
Parameters counts higher than 5.
Variable names like Object and Dobject (in calling function Dobject is Object but it needs a fresh one.
If statements on parameters that need basically split it in two (should simply be to functions)
If else statement with return of same variable as a single line (sane people use ternary for that)
Note that I said functions. All of it should have been OO and methods. Would have saved at least some of the parameter hell.
I could go on and on. Do I think the programmer is bad yes (does not even grasp interfaces, dep injection, foreach loops). Is this his best work no. He said that for a one of script like this it just has to work. Not going to be used elsewhere. I disagree as it is a few thousand lines of code that others have to read too.2 -
Init Mud. (A poem)
A Giant Ball of Mud.
Haphazard in structure.
A sprawling, enthralling, duct-taped warning,
Of things to come.
Tumbling down a well-worn path
Of untamed growth and aftermath.
Into Spaghetti-code Jungle.
Where quick and dirty wins the day
And warnings spoken hold no sway
Or fall on deaf ears in the undergrowth.
Tumbling.
Gaining weight.
Bits stuck on.
Bytes taken out.
Patches,
On top of patches,
On top of obsolescence.
Hacked at, uploaded
All elegance eroded.
Made and remade
Then duplicated
Relocated
Refined and redesigned
Suffocated by expedient repair after expedient repair
The original self no longer there
Replaced by something
Unwieldy.
Design resigned to undefined
An architectural mystery
Whose function can no longer be
Seen or gleaned
From obfuscated in-betweens
Of classes
Made and remade
Duplicated.
Abused.
A squirming library of disused.
Pulled at, prodded, committed
Corners cut and parts omitted.
Bug ridden branches fused to a rotting core.
The structure...
The system...
The content...

python machine learning tutorials:
- import preprocessed dataset in perfect format specially crafted to match the model instead of reading from file like an actual real life would work
- use images data for recurrent neural network and see no problem
- use Conv1D for 2d input data like images
- use two letter variable names that only tutorial creator knows what they mean.
- do 10 data transformation in 1 line with no explanation of what is going on
- just enter these magic words
- okey guys thanks for watching make sure to hit that subscribe button
ehh, the machine learning ecosystem is burning pile of shit let me give you some examples:
- thanks to years of object oriented programming research and most wonderful abstractions we have "loss.backward()" which have no apparent connection to model but it affects the model, good to know
- cannot install the python packages because python must be >= 3.9 and at the same time < 3.9
- runtime error with bullshit cryptic message
- python having no data types but pytorch forces you to specify float32
- lets throw away the module name of a function with these simple tricks:
"import torch.nn.functional as F"
"import torch_geometric.transforms as T"
- tensor.detach().cpu().numpy() ???
- class NeuralNetwork(torch.nn.Module):
def __init__(self):
super(NeuralNetwork, self).__init__() ????
- lets call a function that switches on the tracking of math operations on tensors "model.train()" instead of something more indicative of the function actual effect like "model.set_mode_to_train()"
- what the fuck is ".iloc" ?
- solving environment -/- brings back memories when you could make a breakfast while the computer was turning on
- hey lets choose the slowest, most sloppy and inconsistent language ever created for high performance computing task called "data sCieNcE". but.. but. you can use numpy! I DONT GIVE A SHIT about numpy why don't you motherfuckers create a language that is inherently performant instead of calling some convoluted c++ library that requires 10s of dependencies? Why don't you create a package management system that works without me having to try random bullshit for 3 hours???
- lets set as industry standard a jupyter notebook which is not git compatible and have either 2 second latency of tab completion, no tab completion, no documentation on hover or useless documentation on hover, no way to easily redo the changes, no autosave, no error highlighting and possibility to use variable defined in a cell below in the cell above it
- lets use inconsistent variable names like "read_csv" and "isfile"
- lets pass a boolean variable as a string "true"
- lets contribute to tech enabled authoritarianism and create a face recognition and object detection models that china uses to destroy uyghur minority
- lets create a license plate computer vision system that will help government surveillance everyone, guys what a great idea
I don't want to deal with this bullshit language, bullshit ecosystem and bullshit unethical tech anymore.11 -
I made test library a bit happier. Rainbows, fires and happy faces. Before the happy faces i had traditional dots. This is more cancer. I like it. My applications looks much more modern now.
The emoticon list is made by gpt but i've added a simple search function that finds an emoticon if you put a part of the description. It doesn't have to be exact. printf("%s",remo_get("books")) for example.

So the library we used to interact with s3 had this very cool delete function. (Pseudocode)
function delete(bucket, file)
request = buildRequest(bucket, file)
sendRequest(request)
OK
Now imagine how many problems we setup without delete permission, because we assumed this librsry actually returns an error code -
Dont you just love spending like 2 hours playing around with a library and doing some math, on real pen and paper, only to find out the library had a function for what you need already there and available

Context: New to typescript. Writing a thing, doing it for work, good opportunity to stretch my dev legs. Using a propriety lib, alternatives not an option.
Rant begin:
SOOOO, who the fuck thought THIS was a good idea:
1. Lib has minified react in dev (because closed source) meaning no downstream errors AND the entire premise of the lib is that a widget is a react component, so I'm writing typescript react the entire time without downstream errors
2. SHIT docs. By that, I mean there's an API reference page that's so sparse there's literally a set of CRUCIAL interfaces that only say the word 'Interface' on them. That's it. that's what i get. It's an interface. NO FUCKING SHIT SHERLOCK, what the fuck is it though? What's its purpose? Is it an interface for a dog? A dog that has a 'shit' property? or a cat? or a cat eating dog shit? Nobody fucking knows - the docs sure as fuck don't care.
3. No syntax highlighting - editors, IDEs (i've tried a few) can't even find the lib inside this environment, so Code and everything else thinks I'm importing shit that doesn't even exist - so no error prediction, code completion based on syntax of the library, none of that.
4. There are some EXTREMELY basic samples - these samples exclusively use React classes - no function components, no hooks, nada - just classes and even perfect replicas of the sample code display erratic behavior like errors about missing props, so that's mostly FUCKING USELESS
5. And this... this is where the straw breaks the fucking camel's back... there's no... there's no hot reloading... Do you know what that (in conjunction with the previous 4 fuckups) means?
When I write anything or I fuck up (which of course I'm doing every time I write half a line because how the fuck?) I have to restart the client and server EVERY FUCKING TIME and manually test to see if the error (THAT ONLY GETS REPORTED IN THE LOCAL UI) is gone or different.
Then, once I see the error, it isn't an error: it's the minified React error-decoder link and guess what? It isn't really clickable a link OR copyable, meaning that every FUCKING time I get a new error, I have to MANUALLY TYPE A FUCKING 50 CHAR URL TO FIND OUT A GENERIC REACT ERROR MESSAGE WITHOUT A LINE NUMBER OR ANY FUCKING CONTEXT. I HAVE TO DO THIS CONSTANTLY TO SEE IF ANYTHING I'M DOING EVEN WORKS.
6. There's no github to complain to the maintainers or search for issues because it's NOT FUCKING OPEN SOURCE so there is literally nothing to be fucking done about it.
This is due in a week and a half, found out about it last Friday. How's your day going?
PS: good to be back after a long respite from dev ranting.1 -
I really hate PHP frameworks.
I also often write my own frameworks but propriety. I have two decades experience doing without frameworks, writing frameworks and using frameworks.
Virtually every PHP framework I've ever used has causes more headaches than if I had simply written the code.
Let me give you an example. I want a tinyint in my database.
> Unknown column type "tinyint" requested.
Oh, doctrine doesn't support it and wont fix. Doctrine is a library that takes a perfectly good feature rich powerful enough database system and nerfs it to the capabilities of mysql 1.0.0 for portability and because the devs don't actually have the time to create a full ORM library. Sadly it's also the defacto for certain filthy disgusting frameworks whose name I shan't speak.
So I add my own type class. Annoying but what can you do.
I have to try to use it and to do so I have to register it in two places like this (pseudo)...
Types::add(Tinyint::class);
Doctrine::add(Tinyint::class);
Seems simply enough so I run it and see...
> Type tinyint already exists.
So I assume it's doing some magic loading it based on the directory and commend out the Type::add line to see.
> Type to be overwritten tinyint does not exist.
Are you fucking kidding me?
At this point I figure out it must be running twice. It's booting twice. Do I get a stack trace by default from a CLI command? Of course not because who would ever need that?
I take a quick look at parent::boot(). HttpKernel is the standard for Cli Commands?
I notice it has state, uses a protected booted property but I'm curious why it tries to boot so many times. I assume it's user error.
After some fiddling around I get a stack trace but only one boot. How is it possible?
It's not user error, the program flow of the framework is just sub par and it just calls boot all over the place.
I use the state variable and I have to do it in a weird way...
> $booted = $this->booted;parent::boot();if (!$booted) {doStuffOnceThatDependsOnParentBootage();}
A bit awkward but not life and death. I could probably just return but believe or not the parent is doing some crap if already booted. A common ugly practice but one that works is to usually call doSomething and have something only work around the state.
The thing is, doctrine does use TINYINT for bool and it gets all super confused now running commands like updates. It keeps trying to push changes when nothing changed. I'm building my own schema differential system for another project and it doesn't have these problems out of the box. It's not clever enough to handle ambiguous reverse mappings when single types are defined and it should be possible to match the right one or heck both are fine in this case. I'd expect ambiguity to be a problem with reverse engineer, not compare schema to an exact schema.
This is numpty country. Changing TINYINT UNSIGNED to TINYINT UNSIGNED. IT can't even compare two before and after strings.
There's a few other boots I could use but who cares. The internet seems to want to use that boot function. There's also init stages missing. Believe it or not there's a shutdown and reboot for the kernel. It might not be obvious but the Type::add line wants to go not in the boot method but in the top level scope along with the class definition. The top level scope is run only once.
I think people using OOP frameworks forget that there's a scope outside of the object in PHP. It's not ideal but does the trick given the functionality is confined to static only. The register command appears to have it's own check and noop or simply overwrite if the command is issued twice making things more confusing as it was working with register type before to merely alias a type to an existing type so that it could detect it from SQL when reverse engineering.
I start to wonder if I should just use columnDefinition.
It's this. Constantly on a daily basis using these pretentious stuck up frameworks and libraries.
It's not just the palava which in this case is relatively mild compared to some of the headaches that arise. It's that if you use a framework you expect basic things out of the box like oh I don't know support for the byte/char/tinyint/int8 type and a differential command that's able to compare two strings to see if they're different.
Some people might say you're using it wrong. There is such a thing as a learning curve and this one goes down, learning all the things it can't do. It's cripplesauce.12 -
JavaScript libs have a massive problem with quality and especially with quality of documentation and error reporting
For the entire day I've been staring at this stupid error and can't figure it out. The documentation stating that the source function sets the source dir, but not actual saying what 'source dir' means or what paths are resolved against it is no help either
npm is actually really awesome but almost every library I've tried just fucking sucks3 -
So i'm visiting the JavaScript bubble every now and then when i'm writing on the userscript i develop to fix bugs in our ticketing system or fix some clients website they negelected. Every time i'm searching for answers to the weird problems that inevitably turn up i have to filter out all the threads that derail with the classic 'google jQuery basic arithmetic plugin' craziness to find an actual vanilla solution to my problem.
All the time i wonder why on earth people put up with this framework hell. This is part serious question and part rant but seriously, how did we come to this? With all that jQuery, React, Node, whatever stuff i'm kinda losing the overview over what's even todays standard. I always try to keep my code as vanilla as possible without using external libraries. But it seems the entire web development industry is heading the completly other way. I tried to look into a few frameworks but i never really see the appeal. Just now i looked up react native because the last 20 rants talked about it and immediately noped out because they fucking create a DOM in js, why the fuck would you do this?!
Worst thing about this framework shithole is that some frameworks are beeing pulled into the mix for very weird and unnecessary reasons. Best example is a charts library i recently used to visualize a database of temperatures that was completely written in native js but pulled jQuery in for the equivalent of window.addEventListener('load',function(stuff)) and i was furious. I rewrote the code and could throw out the jQuery dependency with no problem. What the fuck is wrong with people?
Alright since you made it here: I'm not trying to throw any of you under the bus for using frameworks. I just fail to understand why you would use these. To each their own and unless your site has the performance of the ticketing system i use at work that takes like 15 seconds to load one fucking page i won't complain at all. But pull in a framework just to do a task you can easily do in native js in remotely the same timeframe you are on my list.2 -
Just found my first little game I wrote in c++ and opengl(like 5yrs ago). Need to rename over 300 file names, class names and for each class their members names and function names now because ewww how can you call vars in programming like that. Porting it to Linux now. Library linking is working yet. I remember how awful it was to do that shit in vs. In Linux its ez. Also wrote a makefile because vs always compiled my whole project every time I ran it (for whatever reason).
I think that's what I'm going to be doing as a side project this week.2 -
Other peoples' code... (in C++)
I am finding what some people consider good code is not as described. I found a class that provides strings. Great it gives me paths and stuff. I incorporated it in a new project.
segfaults
Hmmm, it must have an init function... It does, but not in the class. It has a friended init function:
friend init_function(). If this function is not created and called external to the class then the class will segfault...
okay...
I implement this. I use code from another project that implements this correctly. The friend class allows the private constructor to be called to create the main instance of the class. So its a fucking cryptic ass singleton. I look at this class. It uses a macro to decide what to function call in the class. The class already has function names for each call it needs to make. The class is literally a string lookup table. I vow to redo this shitty code, someday...
I start to wonder what other fragile code I will find. Not long later I keep getting errors on malloc. Like any malloc that is called results in a segfault. The malloc is not at fault though. I run valgrind and find a websocket library is returning an object a different size than the header file describes.
WTF...
Somebody has left an old ass highly modified definition of the websocket header in a location in that I include headers (partly my fault). I eliminate that from my include path. All is well, everything behaves. I will be making sure this fucking header is not used and it is going to die. Wasted a bunch of time.
Lessons learned: some code is just fucked and don't leave old ass shit you tried laying around.5 -
This is a question and a rant about my frustrations with an API description. First take a look at this usage information for a library I have been playing with:
https://github.com/avaneev/avir/...
Now my first question: Is it clear as to you what the formats are for the InBuf and OutBuf parameters are?
Now, read his response to people (including me) struggling with determining the format of the buffers for this resize function:
https://github.com/avaneev/avir/...
Does the guy come across as condescending as hell? Am I reading into this? It is like the guy takes every opportunity to find fault with people not understanding the details he didn't put in his API description. I would find it difficult to have to work with someone like this.
The irony about this is the description of his code makes me think it is going to magically create this wonderfully rescaled image preserving details. The result is that a standard bilinear filtering scaling function looks practically the same. I saw no real perceptible improvements of his code over the scaler I tested against. When I adjusted parameters using presets he provided it didn't improve the results and added artifacts I could not accept. His scaler is also at least a magnitude slower than the bilinear version. So the code is pretty much a non-starter for my current project.
Ah well, I appreciate him posting the code and making it a very permissive license. That part is really cool.16 -
Messing with three.js library. Now imagine I have a letter in 3D, from which I removed all the faces and replaced vertices with white dots (plexus effect), and all around are like thousands of dots. Now I wanted to put single sprite somewhere on that letter. So I wrote a short script doing that. Fast forward an hour. I am figuring out, why the FPS significantly dropped to like 0.5 fps or what. Checking various browsers, even downscaling image from 512x512 sprite to 64x64, checking whole stackoverflow why is just one fucking sprite causing a lot of trouble and such an fps drop. Trying everything except... I wrote that function inside loop rendering those thousands dots all around. Lol my computer almost catched in fire rendering that shit.
Must to say, in chrome it had 0.5fps, mozilla had around 15-20 fps which is A LOT better.1 -
We used a javascript library before on our project. While reading the documentation, it states that you need to put the ajax response on an .addRow() function in json array.
That was what we did, but it keeps on throwing tons of errors. In the end, we visited our senior dev. Turns out, the function needs an array and not a json array.
I stopped reading documentations since then. And our senior dev stopped talking to us. Hahahajk -
Sometimes in our personal projects we write crazy commit messages. I'll post mine because its a weekend and I hope someone has a well deserved start. Feel free to post yours, regex out your username, time and hash and paste chronologically. ISSA THREAD MY DUDES AND DUDETTES

Just a quickie
I dont know what im committing...3 -
The setting is a computer lab on campus. The assignment was due tomorrow and I was just finishing up the code. I was a novice at C and programming in general at that time. I finish the ~250 lines of functions or so but behavior of the simple library isn't right. I'm getting wrong values and I cannot find the source - I hate myself for not testing incrementally. Then, after looking for hours piece by piece while looking at references and StackO, I realized that I improperly dereferenced a pointer, something like *(this) instead of (*this) in a function. I didn't even know that I was making a mistake because I missed one of the relevant lectures. After that I realized that the errors thrown by the compiler weren't all that bad...

ok this may look like a lazy ass beginner crying out for spoon feeding( which it kinda is), but i want some real industrial training in non documented Android coding.
For last 2 years i have been reading tons of Android articles and documentation on "how to use this library", "how to add this feature", "what this function of this class does", but not much about how to use it efficiently, like the way its used in industry.
When I interned with a startup, all they wanted from me was to push new design changes, fix layout bugs and work as fastly as i could. I had no time to understand their core code, which had so many things that i could have learned : those mvp/mvvm design/architecture patterns, dependency injections, kotlin , coroutines, state management designs, data bindings, eventbuses and handling, and VIPER,RIBS (I mean, not everything was particularly in their code, i picked up a few keywords from here n there)... a lot of stuff that is used by many apps for their codebase.
I can read up these stuff by myself, but i always end up feeling bored coz frankly, i got no big/valuable project to implement it upon and feel excited about it. I feel that open source projects from OSS companies could be my window, but their chat spaces are also mostly empty to discuss/get some guidance.
I want some specific training about these. Can you guys provide any online/offline course/company training/books in this subject, the best practices?1 -
Pulled my hair out over one today (and a week ago when I first saw the issue)
Setting up development environment. Created test user and test database and used mysqldump to copy data over.
MySQL was executing a function as the wrong user. Checked my config files, checked my config reader, checked my database connection, checked checked checked. Checked everything twice, I felt like Santa.
Changed the password in the config file to make sure it was logging in right. It threw an error still but not one I had expected so I figured the login still worked (My bias was that I thought the config file was not working or the mysql library was caching authentication. Both were wrong but this blinded my debugging. Foolish, I have forgotten my training)
Logged into the database directly via client. *didn't bother executing the function because I was only testing auth*
Think
Think
Think
Search entire project for database username. It's gotta be hard coded by accident SOMEWHERE.
It's not.
Why
Why
Why
Wait.
-- Flashback to how the test db was created -- What's actually in this damn script?
DEFINER `production_user` CREATE PROCEDURE `old_db`.`procedure_name`
Two issues: definer is old user (this is the error I was seeing) and its creating the procedure on the old db (this would be the next error I would have found if I kept going)
Fuck mysqldump. Install mysqldbcopy. Works
Put hair back in head. -
Once upon a time aka last week,
Was trying to fix an industrial automation software coded in Codesys. My company's standard library is riddled with bad documentation with a mix of English and German terminology.
Had to find out why a program kept crashing the program upon start up. Long story short and many stressful hours later, I found two functions in the standard library that caused an endless terminal process loop. Had to wrap the function in an 'if statement' so it would only run once. Function should have done this by default. -
Going through another department's API documentation and wrapper library where it has documented samples on how to use it. One of the samples specifically shows how to disable HTTPs requests for when retrieving customer info but it also states in the documentation to specifically NOT USE this disable function.
When it comes to customer info, I don't know why the fuck you would allow an override option to do everything over unsecure requests, and even document about it! -

Wonderful experience today
I'm scraping data from an old system, saving that data as json and my next step is transforming the data and pushing it to an api (thank god the new system has an api)
Now I stumbled upon an issue, I found it a bit hard to retrieve a file with the scraper library I'm using, it was also quite difficult to set specific headers to download the file I was looking for instead of navigating to the index of the website. Then I tried a built-in language function to retrieve the files that I needed during the scrape, no luck 'cause I had to login to the website first.
I didn't want to use a different library since I worked so hard and got so far.
My quick solution: Perform a get request to the website, borrow the session ID cookie and then use the built-in function's http headers functionality to retrieve the file.
Luckily this is a throwaway script so being dirty for this once is OK, it works now :) -
I’m paying for GitHub Copilot and it is serving me well in about 40% of the cases. It is nice to not have to type entire utility methods. Sometimes it also try-catches things that I wouldn’t generally do with a new library that I haven’t used before. Pretty cool.
I also used the Cursor IDE, that isn’t very useful in general cases, but helped me read and understand a horrible piece of 200 line-function with extremely cryptic variable names. Sadly, my free quota there ended.

One of the worst practices in programming is misusing exceptions to send messages.
This from the node manual for example:
> fsPromises.access(path[, mode])
> fsPromises.access('/etc/passwd', fs.constants.R_OK | fs.constants.W_OK)
> .then(() => console.log('can access'))
> .catch(() => console.error('cannot access'));
I keep seeing people doing this and it's exceptionally bad API design, excusing the pun.
This spec makes assumptions that not being able to access something is an error condition.
This is a mistaken assumption. It should return either true or false unless a genuine IO exception occurred.
It's using an exception to return a result. This is commonly seen with booleans and things that may or may not exist (using an exception instead of null or undefined).
If it returned a boolean then it would be up to me whether or not to throw an exception. They could also add a wrapper such as requireAccess for consistent error exceptions.
If I want to check that a file isn't accessible, for example for security then I need to wrap what would be a simple if statement with try catch all over the place. If I turn on my debugger and try to track any throw exception then they are false positives everywhere.
If I want to check ten files and only fail if none of them are accessible then again this function isn't suited.
I see this everywhere although it coming from a major library is a bit sad.
This may be because the underlying libraries are C which is a bit funky with error handling, there's at least a reason to sometimes squash errors and results together (IE, optimisation). I suspect the exception is being used because under the hood error codes are also used and it's trying to use throwing an exception to give the different codes but doesn't exist and bad permissions might not be an error condition or one requiring an exception.
Yet this is still the bane of my existence. Bad error handling everywhere including the other way around (things that should always be errors being warnings), in legacy code it's horrendous.6 -
I'm working with a nice piece of code written 6 years ago by somebody who isn't in the company anymore and only the fact that they live on the other side of the continent prevents me from physically strangling them.
They must have thought that they were very smart trying to use JavaScript as a functional language. A shitload of library-specific decorators that ultimately don't do shit except for raising the cognitive load of anybody who hasn't worked with it before. Why the fuck did you use 'curry' in a function that then is never called in a functional manner? Because fuck me, go check the documentation of ramda because you obviously have too much time at work if you ask questions, just to learn fuck all.
It fascinates me how people take this steaming pile of shit that is JavaScript and then try to work against all its design assumptions to create something that is even more slimy, disgusting and smelly. It shows a radical misunderstanding of what you're even working with.
Take shit, add straw and you might have a docent construction material. Take shit, sprinkle it with chilli and try to eat it and it's just hot shit. But at least you will make everyone else try to find out why the fuck is that chilli in there because why would you expect it there. I'm a coprologist, not a cook.2 -
So today I learnt that babel/runtime-corejs2 is a lib which makes babel more optimised by refactoring most of its function calls. So I need to import a library..... to gain more performance out of an existing library.... I mean you could literally refactor babel instead of asking people to import another package in your project 🤦♂️6

Rust noob Q:
Given x a variable on the heap, e.g.
let x = String::from("Hello, devRant!");
Then, given some function that I didn't write (from a library) that takes ownership of its argument:
fn some_function(y: String) -> bool { ... }
How would you handle this situation:
if some_function(x) {
another_function(x); // not ok, because x has gone out of scope in the line before
}
Is it idiomatic to just clone() x in the first call? That seems bad practice, because it's the second (or some other additional) call that needs x. What should I be doing instead?8 -
I've just joined a new company out of despair after several month out of jobs without being able to even get interviews.
I've been warned about the code being a bit behind with modern Android stack, they needed to migrate from rx to coroutine and compose is not a priority at the moment.
Fine with it, I like handling and planning migration, that's a nice challenge.
But if only that were the only problems !! Far from it, the code is a formidable mess, I've never seen so much amateurism... Most of it was written from the previous Lead Dev who stayed there for years and touched everything with their very bad practices.
I don't even know where to start honestly...
While the code is in Kotlin, it stink Java. Nothing wrong about Java, but if you code in kotlin, you need to understand what kotlin try to achieve. And that's not the case here. There is freaking nullable everywhere, for no reason at all, the data classes contains lot of var in their constructors, equals are override to compare only one or 2 params and no hashcode override with it.
Sealed class, what for ?! Let me just write a List<Pair<Enum, Any>> and cast your any depending on the enum !
Oh and you know what, let's cast everywhere, no check, and for once no null safe, there is enough nullable in the code !
What about the reactive part ? well let's recreate a kind of broken eventbus with rx ! Cause why not ?!
The viewmodel observable don't contain data, they just contain enum for the progress of the states we're checking.
In the viewmodel function we update that enum states and emit it to be observed and make the data available as a var for the view to pick it up when needed.
But why put the business logic in the viewmodel, let's put in the views, and grab and check the variable contain in the viewmodel whenever it fits.
Testing the business logic ? uh let me just test my variable initialisation in the viewmodel instead.
The vm, the views, make about 2000 lines, the test over 3000, and not a single test really test the business logic in it ! I've made big refactoring we're all the tests stayed green, while the function are full of side effects ! WTF ?!
Oh and what about that migration from rx to coroutine ? well better not break the existing code and continue writting like rx, everything is cold flow ! We just need to store a boolean saying if we already did our call to the data layer then we decide to start our flow or not.
As for the RecyclerView, having too many viewHolder is just so annoying, let's put all our different views in one, and hide what we don't need.
Keystore has been push on the repo, but it's private no ? So who cares ?!
And wait i'm not done ! Some of the main brick of the apps depends on library that hasn't been updated for years, and you know what... yes they were hosted on Jcenter and it's only now that they decide to do something about it, we we're warned about the sunset of jcenter 2 years ago !!!!
So what about compose ? What do you want with compose ?! there is no design system in that app obviously, so don't even think about it !
And there... among all of that mess, I'm supposed to do code review... how the fuck do you do a code review when all the code that is around stink ?!
And there is so much more but by now I'm afraid you're thinking i'm just pissing on the old code like everyone... but damn I guarantee, that's the worst code I've ever seen, and i've work on more than 15 app from small to big on different contract with a lot of legacy code, but nothing that bad !1 -
Hey guys!
Once again, I got a little stumped when writing one thingmajig in Python.
I am normally not a programmer (Work as sysadmin), so I don't really know all the fancy abstract ways things are done "properly", which is why I need to ask here:
I have a program, separated into parts. The "core" is a part that sets commandline argument structure (using the argparse library), loads master configuration file, sets up the main logging facility, and then proceeds to load "plugins" - python files with one or more classes that implement one specific abstract class that forces them to implement a common interface of init, run, cleanup functions.
The core then proceeds to initialize those classes, run the "run" function, and run the "cleanup" function.
If the plugin class throws a Warning, it is only logged and runtime continues. If it is anything else, the program logs it and stops.
Now, the issue is, sometimes, a user may want to continue even if a non-warning occurs.
Lets say that I am creating a user, and the user already exists. Sometimes, the program user might want to continue with further plugin execution. And what I was told was to implement specific commandline switches that force continuation of runtime despite the plugin failing.
How should I implement it? The most obvious thing is to add a specific switch for every plugin, but that is exactly what I am trying to evade. I want to have the core as abstract as possible.
Other solution I thought of is to have a file of some sort that would list extra switches to implement, then it would be up to the class to implement if it uses the switch or not (I pretty much pass the entire Namespace received from parse_args() function), but this also feels kinda hackish.
I thought about having some sort of function that the plugin could call in the core to add a new argument, but at the point that plugins start loading, the argument parser is already compiled and cannot be changed further.
Any other ideas of how to re-implement the program are also welcome! I may not do it this times, but I'd at least learn something new again.3 -
Why the fuck would you use a Java Optional in your Scala library. As a Scala novice I just spent about 30 minutes wondering why my map function wouldn't compile 😠
-
Fuck JS. I want to import file and it just gives errors. In PHP for few years it never happens. You check if namespace is correct it always imports without problems. Fuck you JS creators. It asks to install a library, but I am not fucking importing a library. I am just importing my own created simple file. Fuck you.

Okay say I'm compiling a windows binary but I need to call a function from a linux library when running on cygwin. How would one go about doing this? Does it even make sense?
My idea is compiling a dll with one function that links against the linux lib and calls the function. Then just load the dll when needed.
Kinda new to linking stuff so any input is appreciated2 -
Stuck in debugging a python script (using 'requests' library to achieve 'curl' type function) for the last 2 hours
Worked fine yesterday in Python REPL.. Throws exception when put in a long exisitng .py script.. Works fine again when put in Python REPL
Found out that when in REPL, I am careful to import 'requests' library every time but ignored when typing in .py script
(Feeling stupid)
Lesson learned: Don't use "generic exceptions"!! They never let you know what the real problem is.1 -
Okay, so I need a Twitter client library for my Python app. Surely there's a decent one out there, right?
> Goes to Twitter's developer site
There are links to nine different Github repos.
> Takes a look at the one with the most stars
Every method of the API class is @property decorated and returns the result of a function that creates an entirely new class, and then returns a new function that creates an instance of the new class and calls one of its methods that happens to actually make the damn API call.
Alright then...
> Takes a look at the one with the second most stars
All method names are PascalCased.
Please help😭 -
I am trying to decompose a 3D matrix using python library scikit-tensor. I managed to decompose my Tensor (with dimensions 100x50x5) into three matrices. My question is how can I compose the initial matrix again using the decomposed matrix produced with Tensor factorization? I want to check if the decomposition has any meaning. My code is the following:
import logging
from scipy.io.matlab import loadmat
from sktensor import dtensor, cp_als
import numpy as np
//Set logging to DEBUG to see CP-ALS information
logging.basicConfig(level=logging.DEBUG)
T = np.ones((400, 50))
T = dtensor(T)
P, fit, itr, exectimes = cp_als(T, 10, init='random')
// how can I re-compose the Matrix T? TA = np.dot(P.U[0], P.U[1].T)
I am using the canonical decomposition as provided from the scikit-tensor library function cp_als. Also what is the expected dimensionality of the decomposed matrices.1 -
Code comments are good and all, but there's a time and a place for them. They're more or less an opinionated free-form version of what code is doing.
In a library, they're good for documentation. However in a platform, it makes less sense. Especially one which is changing at quite a fast rate (though it has matured in recent months).
Dont get me wrong, we aren't doing wades of horrible, unintelligible code. We need to be sure of what happens when we call a function, so we make sure the signature is always correct.
def do_good_things(puppies): # "good things" is opinionated. Say what you're doing

tfw you're learning a new library and a function gives an error suggesting xyz in data. You assume you're using the function wrong. 5 hours later...turns out there is xyz in data ya big dummy!

Has anyone else used the Decimal module in python?
And if so do you know why it returns
"AttributeError: type object 'decimal.Decimal' has no attribute 'power'"?
According to the documentation
https://docs.python.org/3/library/...
...theres a power() function.
Doing
decimal.power()
Decimal.power()
power(x, y)
No matter how I call it, it always returns an error indicating power() doesn't exist and I'm scratching my head.4 -
How deep do you go when trying to find a solution?
I have a need for combinations of items. I have used built in functions in Python for this. When I first used those I wanted to learn how they worked internally. I read through the source and thought that was cool. I don't think I really understood that code very well.
Now I need the same solution in C++. There is not a prebuilt combinations function in C++. There is a prebuilt verion of next_permutation. I can build upon that to make my combinations code. However, I am in the middle of trying to make something work. So I found this nice SO question:
https://stackoverflow.com/questions...
The code I ended up using:
template<class RandIt, class Compare>
bool next_k_permutation(RandIt first, RandIt mid, RandIt last, Compare comp){
std::sort(mid, last, std::bind(comp, std::placeholders::_2, std::placeholders::_1));
return std::next_permutation(first, last, comp);
}
template<class BiDiIt, class Compare>
bool next_combination(BiDiIt first, BiDiIt mid, BiDiIt last, Compare comp)
{
bool result;
do{
result = next_k_permutation(first, mid, last, comp);
}while(std::adjacent_find(first, mid, std::bind(comp, std::placeholders::_2, std::placeholders::_1)) != mid);
return result;
}
I am mostly able to figure out what is going on with the templates. I still am not understanding the basic algo behind permutations.
Our data set is tiny. 4 items max. So efficiency isn't really a big issue here.
How long do you spend learning how it works versus just finding a solution for the task at hand?
In general I need to spend more time learning different kinds of algorithms. So I should probably add permutations to that list of ones to study.1 -
Is using getx's `ever` function a code smell? I'm using getx as a library rather than a framework ie state management instead of wrapping the app in it and using their widgets
My background from writing reactive code in vuex is that whenever a watched variable in the overarching store is updated, it automatically calls its listeners and re-renders the view. However, my flutter widgets remain stagnant except I explicitly mount the ever worker and call setState on a local field basically duplicating the store variable/field. It feels hacky to me tbh and leads to errors about calling setState on non-mounted screens, which I'm circumventing by checking if mounted (another hack)
It feels contrived like Band-aid over an actual problem. Is there a more natural way to propagate changes? I'm neither using getBuilder nor obx cuz a significant portion of my code entails computing stuff rather than just outputting data off an api. I want ui decisions to reside on my statefulWidget rather than migrating them to getx controller
Is this really how the project functions, should it be used a specific way, or am I missing something?6 -
4 hours wasted due to a rather strange "scope poisoning" bug... it was really fucking strange.
Had to move the 5 lines of code, above where the error happened, to a private function.
The 5 lines just called an XLSX library which read a given file and returned an array. I don't know how but the thing somehow messed with my Soap client call one line below. The culprit must have been some IO resource handle which didn't get destroyed when in the same scope due to persisting object references..1
