0. Plan before you code. Document everything. You won't remember either your idea or those clever implementations next week (or next month, or next year...).
1. Don't hack your way through, unless that's what you intend to do. Name your variables, functions etc. neatly: autocomplete exists!
Protip: Sometimes you want to check a quick language feature or a piece of code from one of your modules. Resist the urge to quickly hack in the test into your actual project. Maintain a separate file where you can quickly type in and check what you're looking for without hacking on your project (For example, in Python, you can open a new terminal or IDLE window for those quick tests).
2. Keep a quiet environment where you can focus. Recommend listening to something while coding (my latest fad is on asoftmurmur.com). Don't let anything distract you and throw your contextual awareness out of whack.
3. Rubber ducks work. Really. Talking out a complex piece of logic, or that regex or SQL query aids your mind greatly in grasping the concept and clearing the idea. Bounce off code and ideas with a friend or colleague to catch errors and oversights faster. Read more here: https://en.wikipedia.org/wiki/...
4. Since everyone else is saying this (and because it merits saying), USE VERSION CONTROL. Singular most important thing to software development aside from planning and documenting.
5. Remember to flout all of the above once in a while and just make a mess of a project where you have fun throwing everything around all over the place. You'll make mistakes that you never thought were possible by someone of your caliber :) That's how you learn.
Have fun, keep learning!3 -
Every day.
I am a PHP developer.
Yeah, "another PHP is awful" rant... no, not really.
It's just unsuitable for some ambitious projects, just like Ruby and Python are.
First of all, DO NOT EVER use Laravel for large enterprise applications. The same goes for RoR, Django, and other ActiveRecord MVCs.
They are all neat frameworks for writing a todo app, as a better-than-wordpress flexible blogging solution, even as a custom webshop.
Beyond 50k daily users, Active Record becomes hell due to it's lazy fat querying habits. At more than a million users... *depressed sigh*.
PHP is also completely unsuitable for projects beyond 5M lines of code in my opinion. At more than 25M lines... *another depressed sigh*.
You can let your devs read Clean Code and books about architecture patterns, you can teach them about SOLID & DRY, you can write thousands of tests... it doesn't matter.
PHP is scaffolding, it's made of bamboo and rope. It's not brick or concrete. You can build quickly, but it only scales up to a certain point before it breaks in multiple places.
Eventually you run into patterns where even 100% test coverage still doesn't guarantee shit, because the real-life edge cases are just too complex and numerous.
When you're working on a multi-party invoicing system with adapters for various tax codes, or an availability/planning system working across timezones, or systems which implement geographical routefinding coupled to traffic, event & weather prediction...
PHP, Python, Ruby, etc are just missing types.
Every day I run into bugs which could have been prevented if you could use ADTs in a generic way in PHP. PHP7 has pretty good typehints, and they prevent a lot of messy behavior, but they aren't composable. There is no way to tell PHP "this method accepts a Collection of Users", or "this methods returns maybe either an Apple or a Pear, and I want to force the caller to handle both Apple/Pear and null".
Well, you could do that, but it requires a lot of custom classes and trickery, and you have to rewrite the same logic if you want to typehint a "Collection of Departments" instead of "Collection of Users" -- i.e., it's not composable.
Probably the biggest issue is that languages with a (mostly) structural type system (Haskell, Rust, even C#/JVM languages to some degree, etc) are much slower to develop in for the "startup" era of a project, so you grab a weak, quick prototyping language to get started.
Then, when you reach a more grown up phase, you wish you had a better type system at your disposal...28 -
Inspired by @h3ll, this is a combination of current and former coworkers:
Awkward Wizard:
This guy has the social skills of a microwaved dog turd. He is a genius, but working with him is about as uncomfortable as sticking a grill skewer in your eye and twisting it repeatedly until close of business. He laughs at inappropriate times, and every time he does, an unborn child tears its own ears off. He explains things in a way that only himself and Satan understand, then talks to you like you're a child when you don't follow his logic. He is the guy you hide when the CEO is around. His code is immaculate.
Backstab McGillacutty:
This bowl of bile is the son of a bitch that takes credit for everybody else's work. When you do something good, he was miraculously involved, but when you mess up, this twat is the dicknose that brings it up in retrospective and calls you out by name to the boss. You can usually find these guys talking shit about the CTO, until the boss quits. Then they buddy up with the CTO and become a Joel Osteen-esque evangelist for everything the CTO wants in a shitty, underhanded attempt to climb the ladder. Fuck this guy.
Professor Fuckwaffle:
This coworker used to teach Computer Science classes. Their resume is amazing, and they can speak to the most complex of design principles. This is the shitstain that you hire because of their skill and knowledge only to find out that ol' fuckwaffle can't apply the shit they spout to save their wretched lives. You'll spend more time listening to fuckwaffle lecture than you will reviewing their code (because they cant fucking write any!) You know the saying, those who can, do, and those who can't, teach? Yeah, that shit was written for Fuckwaffle.
Last but not least:
Scrumdumb:
This guy isn't even a coder. This guy is worse than the the scum you pour out of the bottom of a slow-cooker that you forgot to wash last time you made chicken. He's a non-technical PM. You know the type, right? He usually says "cloud infrastructure," "paradigm," "algorithm," "SDLC," etc but has no grasp of any of them. He often opens his dumpster to spout off something like "You can just create a new class for that" while talking about HTML. I won't waste any more breath on Scrumdumb, he already creates enough work for me.3 -
"Can you work on this ticket? It's kind of urgent."
-- "OK"
"And could you please not refactor? Just get this done."
-- "Why? What's the issue?"
"The logic is complex. We should not break it."
-- "Erm, that's what the tests are for. So yes, if the need arises, I'll refactor. The tests are my guidelines if the logic breaks or not."
There's a reason we create tests. So let's not hinder code base improvements by some random fear that stuff might break.
If breaks due to refactoring, we'll fix it by adding a valid test case during and then fixing the bug.
If my refactoring does not break the tests, I'll assume the code base is stable.
If your code is untested, then we have a complete different problem.3 -
Juniors are a fun bunch to work with.
Over confident, hero complex of that fresh graduate high, and then thrown in to the real world! Where there hopes and dreams are crushed in minutes when they see what monolithic applications really look like!!
But don't let that overwhelm you, your not going to be changing all of it any time soon, hell some of this code hasn't been touched in 5+ years and still works without fail.
Don't stress about the work load, you can only write 1 line of code at a time anyway, and hell, even seniors make mistakes.
The key about being able to manage this beast is simple, break it! Because the more you break it, the more you'll understand how a project is put together, for better or worse. Learn from the examples in front of you, and learn what not to do in the future 😎
But more importantly, plan your changes, whiteboard the high level logic of what it is you want to add, then whiteboard in the current codebase and determine where to slice this bitch up, then when it all looks well and good, take out your scalpel and slice and dice time.
Don't worry, your changes aren't going to production anytime soon, hell, you'll be lucky to get past the first pull request with this working 100% the first time, and that's a good thing, learn from tour short comings and improve your own knowledge for the next time!2 -
I'm convinced code addiction is a real problem and can lead to mental illness.
Dev: "Thanks for helping me with the splunk API. Already spent two weeks and was spinning my wheels."
Me: "I sent you the example over a month ago, I guess you could have used it to save time."
Dev: "I didn't understand it. I tried getting help from NetworkAdmin-Dan, SystemAdmin-Jake, they didn't understand what you sent me either."
Me: "I thought it was pretty simple. Pass it a query, get results back. That's it"
Dev: "The results were not in a standard JSON format. I was so confused."
Me: "Yea, it's sort-of JSON. Splunk streams the result as individual JSON records. You only have to deserialize each record into your object. I sent you the code sample."
Dev: "Your code didn't work. Dan and Jake were confused too. The data I have to process uses a very different result set. I guess I could have used it if you wrote the class more generically and had unit tests."
<oh frack...he's been going behind my back and telling people smack about my code again>
Me: "My code wouldn't have worked for you, because I'm serializing the objects I need and I do have unit tests, but they are only for the internal logic."
Dev:"I don't know, it confused me. Once I figured out the JSON problem and wrote unit tests, I really started to make progress. I used a tuple for this ... functional parameters for that...added a custom event for ... Took me a few weeks, but it's all covered by unit tests."
Me: "Wow. The way you explained the project was; get data from splunk and populate data in SQLServer. With the code I sent you, sounded like a 15 minute project."
Dev: "Oooh nooo...its waaay more complicated than that. I have this very complex splunk query, which I don't understand, and then I have to perform all this parsing, update a database...which I have no idea how it works. Its really...really complicated."
Me: "The splunk query returns what..4 fields...and DBA-Joe provided the upsert stored procedure..sounds like a 15 minute project."
Dev: "Maybe for you...we're all not super geniuses that crank out code. I hope to be at your level some day."
<frack you ... condescending a-hole ...you've got the same seniority here as I do>
Me: "No seriously, the code I sent would have got you 90% done. Write your deserializer for those 4 fields, execute the stored procedure, and call it a day. I don't think the effort justifies the outcome. Isn't the data for a report they'll only run every few months?"
Dev: "Yea, but Mgr-Nick wanted unit tests and I have to follow orders. I tried to explain the situation, but you know how he is."
<fracking liar..Nick doesn't know the difference between a unit test and breathalyzer test. I know exactly what you told Nick>
Dev: "Thanks again for your help. Gotta get back to it. I put a due date of April for this project and time's running out."
APRIL?!! Good Lord he's going to drag this intern-level project for another month!
After he left, I dug around and found the splunk query, the upsert stored proc, and yep, in about 15 minutes I was done.1 -
> Root struggles with her ticket
> Boss struggles too
> Also: random thoughts about this job
I've been sick lately, and it's the kind of sick where I'm exhausted all day, every day (infuriatingly, except at night). While tired, I can't think, so I can't really work, but I'm during my probationary period at work, so I've still been doing my best -- which, honestly, is pretty shit right now.
My current project involves legal agreements, and changing agent authorization methods (written, telephone recording, or letting the user click a link). Each of these, and depending on the type of transaction, requires a different legal agreement. And the logic and structure surrounding these is intricate and confusing to follow. I've been struggling through this and the project's ever-expanding scope for weeks, and specifically the agreements logic for the past few days. I've felt embarrassed and guilty for making so little progress, and that (and a bunch of other things) are making me depressed.
Today, I finally gave up and asked my boss for help. We had an hour and a half call where we worked through it together (at 6pm...). Despite having written quite a bit of the code and tests, he was often saying things like "How is this not working? This doesn't make any sense." So I don't feel quite so bad now.
I knew the code was complex and sprawling and unintuitive, but seeing one of its authors struggling too was really cathartic.
On an unrelated note, I asked the most senior dev (a Macintosh Lisa dev) why everything was using strings instead of symbols (in Rails) since symbols are much faster. That got him looking into the benchmarks, and he found that symbols are about twice as fast (for his minimal test, anyway), and he suggested we switch to those. His word is gold; mine is ignorable. kind of annoying. but anyway, he further went into optimizing the lookup of a giant array of strings, and discovered bsearch. (it's a divide-and-conquer lookup). and here I am wondering why they didn't implement it that way to begin with. 🙄
I don't think I'm learning much here, except how to work with a "mature" codebase. To take a page from @Rutee07, I think "mature" here means the same as in porn: not something you ever want ot see or think about.
I mean, I'm learning other things, too, like how to delegate methods from one model to another, but I have yet to see why you would want to. Every use of it I've explored thus far has just complicated things, like delegating methods on a child of a 1:n relation to the parent. Which child? How does that work? No bloody clue! but it does, somehow, after I copy/pasted a bunch of esoteric legacy bs and fussed with it enough.
I feel like once I get a good grasp of the various payment wrappers, verification/anti-fraud integration, and per-business fraud rules I'll have learned most of what they can offer. Specifically those because I had written a baby version of them at a previous job (Hell), and was trying to architect exactly what this company already has built.
I like a few things about this company. I like my boss. I like the remote work. I like the code reviews. I like the pay. I like the office and some socializing twice a year.
But I don't like the codebase. at all. and I don't have any friends here. My boss is friendly, but he's not a friend. I feel like my last boss (both bosses) were, or could have been if I was more social. But here? I feel alone. I'm assigned work, and my boss is friendly when talking about work, but that's all he's there for. Out of the two female devs I work with, one basically just ignores me, and the other only ever talks about work in ways I can barely understand, and she's a little pushy, and just... really irritating. The "senior" devs (in quotes because they're honestly not amazing) just don't have time, which i understand. but at the same time... i don't have *anyone* to talk to. It really sucks.
I'm not happy here.
I miss my last job.
But the reason I left that one is because this job allows me to move and work remotely. I got a counter-offer from them exactly matching my current job, sans the code reviews. but we haven't moved yet. and if I leave and go back there without having moved, it'll look like i just abandoned them. and that's the last thing I want them to think.
So, I'm stuck here for awhile.
not that it's a bad thing, but i'm feeling overwhelmed and stressed. and it's just not a good fit. but maybe I'll actually start learning things. and I suppose that's also why I took the job.
So, ever onward, I guess.
It would just be nice if I could take some of the happy along with me.7 -
So... my girlfriend has a very random work schedule. Sometimes she works 4 days a week sometimes only 1, sometimes only at the weekend sometimes not at all. If only there would be an app to track that... 🤔
She tried quite a few apps on the app store but they were shit/ugly/too complex..etc
Wait.. i’m a developer, i can do that.
So i made a dead simple calendar-like app in javascript+fuseopen.
She selected the colors, background, layout etc..
If she taps on a date it turns red indicating that is a workday, if a workday is tapped it turns back to normal color.
The main logic is:
Main:
If(AppHasSavedWorkdays){
//check if save is current month
LoadCalendarWithWorkdays();
}else{
CreateEmptyCalendarAndSave();
}
She likes it.
Cool, so let’s build this! She has an iphone and my mac is still in the service center so i can’t build🙁
But its okay, i have a mac at my office, we can build there, the only downside is that is 40min of travel.
We take the subway, go to the office, build the app, make a certificate, install to her phone, everything goes as planned.
Coming back we were lucky enough to catch the bus that goes in 30 min intervals, we only had to wait like a minute so life is good 😃
I enter the house, chill down on the bed, pull out my laptop to close the project when a FUCK ME!!!!
I completely forgot to implement a whole else branch on start!!!
Soo the app does nothing when is opened on january 1😂😂
I guess that’s why we have testers and qa.. 😃8 -
New to this but here's my rant I suppose. It bothers me how "non-tech" people kind of devalue what tech people do. Like they have zero understanding of it, so you make something in 30 minutes or an hour that took years of building said skills and involved complex logic and understanding of relational data and because it only took you 30 minutes or an hour it must have been "easy". Or the way you are everybody's free tech advisor with family and friends... And things are said like "I'm not good with this stuff, but you're so good with it". For the record nobody is just "great" at technology or coding from birth its been a 2+ decade craft that I've experimented with and learned and put effort into. So taking into consideration all this effort I have put in to understand all this you say you'll never remember to push that button so you'll just ask me again when the problem arises. Yes because its so fun for me to constantly maintain your electronics because you can't bother to remember to push a button.5

If you need to learn/teach object orientation, these are my approaches (I hate that classic "car" example):
1) Keep in mind games like Warcraft, Starcraft, Civilization, Age of Empires (yes, I am old school). They are a good example of having classes to use, instantiating objects (creatures) and putting them to work together. As in a real system.
2) Think of your program as an office that has a job to do, or a factory that has something to deliver. Classes are the roles/jobs and objects are the workers/employees. They don't need to be complex, but their purpose must be really (really, really) well defined. Just like in a real office / factory.
3) Even better (or crazier), see your classes and objects as real beings, digital creatures in a abstract world, and yourself as a kind of god, who creates species (define classes) with wisdom. Give life when it is the time for them to come into the world (instantiate object) and kill them when they are done with their mission (dispose an object). Give them behavior, logic, conditions to work with, situations where they take action, and when they don't. Make them kinda "smart". Build them able to make decisions and take actions based on conditions. Give them life. Think on your program as an ecossystem. There must be balance, connection, species must be well defined and creatures must work together to achieve a common objective. Don't just throw code and pray for it to run. Plan it.
-----
When I talk about my classes like they are real beings, and programs as mini-worlds, some people say I am crazy, some others say that's passion.
It is both! @__@3 -
The nightmare continues.
Currently dealing with a code review from a “principal” dev (one step above senior), who is unironically called a “legendary dev” by some coworkers. It’s painfully obvious he didn’t read the code, and just started complaining and nitpicking.
It’s full of requests to do things that make absolutely no sense, and would make the code an unmaintainable mess.
• Ex: moving the logic and data collection from the module’s many callers into the module instead of just passing in the data.
• Ex: hiding api endpoint declarations by placing them in the module itself, and using magic instance variables to pass data to it. Basically: using global functions and variables instead of explicit declarations and calls.
• Ex: moving the logic to determine which api endpoint to use, for all callers, into the view.
More comments about methods being “too complex” (barely holds water) right next to comments saying “why are these separate? merge them together!”
Incredulously asking how many times I’m checking permissions and how ridiculous it all is. (The answer? Twice.)
Conflating my “permissions” param and method names with a supposedly forthcoming permissions system overhaul, and saying I shouldn’t use permissions because my code will all have to get rewritten. Even if that were true, and it’s likely not, the ticket still needs to use the current permissions. I can’t just ignore them because they might be rewritten someday.
Requests to revert some code cleanup because the reviewer thought the previous heavily-nested and uncommented versions (with code duplication) were easier to read. Unsurprisingly, he wrote them.
On the same ticket, my boss wants me to remove all styling and clientside validation, debouncing, and error messages from a form. Says “success” and “connection failed” messages are good enough. The form in question sends SMS and email using arbitrary user input for addresses. He also says it shouldn’t be denounced on the server, and doesn’t want me to bother checking permissions. Hello, spam!
Related: the legendary dev reviewer says he can’t think of a reason why we would want to disable the feature for consumers, so I should remove the consumer feature flag.
You can’t make this stuff up.7 -
I just love refactoring :) that feeling when an agonic 50loc method with ifs, loops, streams, other shit shrinks down to 3 lines with descriptive and SRP-compliant method calls.. When you can actually read code as a nicely written story. When there are no rubbish comments, cryptic variables and no overly complex if-else skyscrapers jamming all the logic in one conditional chain. When all the abstractions are designed so nicely and design patterns applied so perfectly that extending either of the components is as easy as a walk in a park.
When everything is nice and neat. Only then can I sleep well and enjoy the autumn :)
just some random thoughts after today's coding session :)5 -
I could bitch about XSLT again, as that was certainly painful, but that’s less about learning a skill and more about understanding someone else’s mental diarrhea, so let me pick something else.
My most painful learning experience was probably pointers, but not pointers in the usual sense of `char *ptr` in C and how they’re totally confusing at first. I mean, it was that too, but in addition it was how I had absolutely none of the background needed to understand them, not having any learning material (nor guidance), nor even a typical compiler to tell me what i was doing wrong — and on top of all of that, only being able to run code on a device that would crash/halt/freak out whenever i made a mistake. It was an absolute nightmare.
Here’s the story:
Someone gave me the game RACE for my TI-83 calculator, but it turned out to be an unlocked version, which means I could edit it and see the code. I discovered this later on by accident while trying to play it during class, and when I looked at it, all I saw was incomprehensible garbage. I closed it, and the game no longer worked. Looking back I must have changed something, but then I thought it was just magic. It took me a long time to get curious enough to look at it again.
But in the meantime, I ended up played with these “programs” a little, and made some really simple ones, and later some somewhat complex ones. So the next time I opened RACE again I kind of understood what it was doing.
Moving on, I spent a year learning TI-Basic, and eventually reached the limit of what it could do. Along the way, I learned that all of the really amazing games/utilities that were incredibly fast, had greyscale graphics, lowercase text, no runtime indicator, etc. were written in “Assembly,” so naturally I wanted to use that, too.
I had no idea what it was, but it was the obvious next step for me, so I started teaching myself. It was z80 Assembly, and there was practically no documents, resources, nothing helpful online.
I found the specs, and a few terrible docs and other sources, but with only one year of programming experience, I didn’t really understand what they were telling me. This was before stackoverflow, etc., too, so what little help I found was mostly from forum posts, IRC (mostly got ignored or made fun of), and reading other people’s source when I could find it. And usually that was less than clear.
And here’s where we dive into the specifics. Starting with so little experience, and in TI-Basic of all things, meant I had zero understanding of pointers, memory and addresses, the stack, heap, data structures, interrupts, clocks, etc. I had mastered everything TI-Basic offered, which astoundingly included arrays and matrices (six of each), but it hid everything else except basic logic and flow control. (No, there weren’t even functions; it has labels and goto.) It has 27 numeric variables (A-Z and theta, can store either float or complex numbers), 8 Lists (numeric arrays), 6 matricies (2d numeric arrays), 10 strings, and a few other things like “equations” and literal bitmap pictures.
Soo… I went from knowing only that to learning pointers. And pointer math. And data structures. And pointers to pointers, and the stack, and function calls, and all that goodness. And remember, I was learning and writing all of this in plain Assembly, in notepad (or on paper at school), not in C or C++ with a teacher, a textbook, SO, and an intelligent compiler with its incredibly helpful type checking and warnings. Just raw trial and error. I learned what I could from whatever cryptic sources I could find (and understand) online, and applied it.
But actually using what I learned? If a pointer was wrong, it resulted in unexpected behavior, memory corruption, freezes, etc. I didn’t have a debugger, an emulator, etc. I had notepad, the barebones compiler, and my calculator.
Also, iterating meant changing my code, recompiling, factory resetting my calculator (removing the battery for 30+ sec) because bugs usually froze it or corrupted something, then transferring the new program over, and finally running it. It was soo slowwwww. But I made steady progress.
Painful learning experience? Check.
Pointer hell? Absolutely.4 -
Programming lesson #5
When logic becomes too complex to solve mentally while coding, writing the requirements and inputs on paper and coming up with pseudocode is a good approach.10 -
"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 -
I once had to make a shitty canvas game as part of a marketing campaign when I worked for an agency, for fuck only knows what. You dragged a shopping trolley back and forth in an aisle, and got points for catching items that fell from the top.
The initial round of feedback had the complaint that sometimes players weren't receiving points for items. I spent a night playing this senseless game over and over, but I never failed to get the points for an item. I was pretty confident that it worked, it wasn't like the logic was complex, so I sent it over.
Second round of feedback had the same complaint. They were getting quite annoyed by it, said that it was a bad user experience. Again, I could not reproduce it at all: the game was an equally tedious waste of life on every device I tried it on.
In exasperation, I asked the sales guy whose pitch it had been to get me a video or a more detailed report. The client was quite arsey, as they saw it, at having to do bug-fixing for us, but they did agree.
Anyway, it transpired that they were angry that players were not receiving the points for the items they *failed* to catch. The way they saw it, the game wouldn't be fun if you were punished for not catching items - so they wanted the player to get ten points for every item on screen, regardless or not of whether they caught it in their trolley. Of course, I thought. Silly me.
I was actually quite impressed at how a marketing department could accidentally undermine the very notion of a game whilst seeking to make one more fun.8 -
Is it just me who sees this? JS development in a somewhat more complex setting (like vue-storefront) is just a horrible mess.
I have 10+ experience in java, c# and python, and I've never needed more than a a few hours to get into a new codebase, understanding the overall system, being able to guess where to fix a given problem.
But with JS (and also TS for that matter) I'm at my limits. Most of the files look like they don't do anything. There seems to be no structure, both from a file system point of view, nor from a code point of view.
It start with little things like 300 char long lines including various lambdas, closures and ifs with useless variables names, over overly generic and minified method/function names to inconsistent naming of files, classes and basically everything else.
I used to just set a breakpoint somewhere in my code (or in a compiled dependency) wait this it is being hit and go back and forth to learn how the system state changes.
This seems to be highly limited in JS. I didn't find the one way to just being able to debug, everything that is. There are weird things like transpilers, compiler, minifiers, bablers and what not else. There is an error? Go f... yourself ...
And what do I find as the number one tipp all across the internet? Console.log?? are you kidding me, sure just tell me, your kidding me right?
If I would have to describe the JS world in one word, I would use "inconsistency". It's all just a pain in the ass.
I remember when I switcher from VisualStudio/C# to Eclipse/Java I felt like traveling back in time for about 10 years. Everyting seemd so ... old-schoolish, buggy, weird.
When I now switch from java to JS it makes me feel the same way. It's all so highly unproductive, inconsistent, undeterministic, cobbled together.
For one inconveinience the JS communinity seems to like to build huge shitloads of stuff around it, instead of fixing the obvious. And noone seems to see that.
It's like they are all blinded somehow. Currently I'm also trying to implement a small react app based on react-admin. The simplest things to develop and debug are a nightmare. There is so much boilerplate that to write that most people in the internet just keep copying stuff, without even trying to understand what it actually does.
I've always been a guy that tries to understand what the fuck this code actuall does. And for most of the parts I just thing, that the stuff there is useless or could be done in a way more readable way. But instead, all the devs out there just seem to chose the "copy and fix somehow-ish" way.
I'm all in for component-izing stuff. I like encapsulation, I'm a OOP guy by heart. But what react and similar frameworks do is just insane. It's just not right (for some part).
Especially when you have to remember so much stuff that is just mechanics/boilerplate without having any actual "business logical function".
People always say java is so verbose. I don't think it is, there is so few syntax that it almost reads like a prose story. When I look at JS and TS instead, I'm overwhelmed by all the syntax, almost wondering every second line, what the actual fuck this could mean. The boilerplate/logic ration seems way to off ..
So it really makes me wonder, if all you JS devs out there are just so used to that stuff, that you cannot imagine how it could be done better? I still remember my C# days, but I admin that I just got used to java. So I can somehow understand that all. But JS is just another few levels less deeper.
But maybe I'm just lazy and too old ...4 -

And he just competed in just few lines with common logic
And i done it but used complex logic

Worst collaboration experience story?
I was not directly involved, it was a Delphi -> C# conversion of our customer returns application.
The dev manager was out to prove waterfall was the only development methodology that could make convert the monolith app to a lean, multi-tier, enterprise-worthy application.
Starting out with a team of 7 (3 devs, 2 dbas, team mgr, and the dev department mgr), they spent around 3 months designing, meetings, and more meetings. Armed with 50+ page specification Word document (not counting the countless Visio workflow diagrams and Microsoft Project timeline/ghantt charts), the team was ready to start coding.
The database design, workflow, and UI design (using Visio), was well done/thought out, but problems started on day one.
- Team mgr and Dev mgr split up the 3 devs, 1 dev wrote the database access library tier, 1 wrote the service tier, the other dev wrote the UI (I'll add this was the dev's first experience with WPF).
- Per the specification, all the layers wouldn't be integrated until all of them met the standards (unit tested, free from errors from VS's code analyzer, etc)
- By the time the devs where ready to code, the DBAs were already tasked with other projects, so the Returns app was prioritized to "when we get around to it"
Fast forward 6 months later, all the devs were 'done' coding, having very little/no communication with one another, then the integration. The service and database layers assumed different design patterns and different database relationships and the UI layer required functionality neither layers anticipated (ex. multi-users and the service maintaining some sort of state between them).
Those issues took about a month to work out, then the app began beta testing with real end users. App didn't make it 10 minutes before users gave up. Numerous UI logic errors, runtime errors, and overall app stability. Because the UI was so bad, the dev mgr brought in one of the web developers (she was pretty good at UI design). You might guess how useful someone is being dropped in on complex project , months after-the-fact and being told "Fix it!".
Couple of months of UI re-design and many other changes, the app was ready for beta testing.
In the mean time, the company hired a new customer service manager. When he saw the application, he rejected the app because he re-designed the entire returns process to be more efficient. The application UI was written to the exact step-by-step old returns process with little/no deviation.
With a tremendous amount of push-back (TL;DR), the dev mgr promised to change the app, but only after it was deployed into production (using "we can fix it later" excuse).
Still plagued with numerous bugs, the app was finally deployed. In attempts to save face, there was a company-wide party to celebrate the 'death' of the "old Delphi returns app" and the birth of the new. Cake, drinks, certificates of achievements for the devs, etc.
By the end of the project, the devs hated each other. Finger pointing, petty squabbles, out-right "FU!"s across the cube walls, etc. All the team members were re-assigned to other teams to separate them, leaving a single new hire to fix all the issues.5 -
TL;DR: At a house party, on my Phone, via shitty German mobile network using the GitLab website's plain text editor. Thanks to CI/CD my changes to the code were easily tested and deployed to the server.
It was for a college project and someone had a bug in his 600+ lines function that was nested like hell. At least 7 levels deep. Told him before I went to that party it's probably a redefined counter variable but he wouldn't have it as he was sure it was an error with the business logic. Told him to simplify the code then but he wouldn't do that either because "the code/logic is too complex to be simplified"... Yeah... what a dipshit...
Nonetheless I went to the party and He kept debugging. At some point he called me and asked me to help him the following day. Knowing that the code had to be fixed anyways I agreed.
I also knew I wouldn't be much of a help the next day due to side effects of the party, so I tried looking at this shitshow of a function on my phone. Oh did I mention it was PHP, yet? Yeah... About 30 minutes and a beer later I found the bug and of course it was a redefined counter variable... My respect for him as a dev was already crumbling but it died completely during that evening2 -
Lets create a library.
Lets use that library in a project.
Lets wrap the library call in a wrapper functione to remove duplicate code.
Lets add an overloaded wrapper call that wraps the wrapper call that calls the library to partially undo the duplicate code removal.
Lets add another overloaded wrapper call that wraps the wrapper call that wraps the wrapper call that calls the library to partially undo the duplicate code removal.
How I love it. Not.
Sometimes redundancy makes sense, especially when it are two lines which make it obvious whats going on vs a single line that leads to a fuckton of overloaded wrapper functions.
Sheeesh.
Today in "code monkeys deserve divine punishment".
Another funny thing is creating a Helper class for Junit 5 tests, making it instantiable and adding to it all kinds of shit like testcontainer creation, applications instantiation, mocks, ....
... Then " crying " why the tests are so slow.
Yeah. Logic. Isolation of concerns, each test should be a stand alone complex.
But that would lead to redundancy... Oh no.
Better to create a global state god object.
Some devs... Really amaze me, especially when they argument in ways that makes one really wonder whether they are serious or just brain dead.14 -
FFUUUuucccckkk me sideways. So I decided to look into USB type-c's power delivery and alt modes. Cause I kinda want to make an adapter card to run my displays over a single cable. TLDR of the rest: USB-C has some huge capabilities which noone is interested in using since its way to complex to handle for what its worth in the end.
Now PD alone is kinda ok to deal with since a lot of powerbanks use it and some hobby guys documented how to work with it. I find it really odd thou that you NEED to use a dedicated IC for using the configuration chanel to negotiate how much power you can draw. Why the USB standard didnt use some simple 5V low speed signalling? Also the standard says that you only have to implement 5v 0.6A with every other power level being optional. (This is also true for cables. Most manufacturers use only the USB 2.0 standard for them and brag about how fast type-C is. ლ(ಠ益ಠლ) )
Now to the alt modes. These motherfuckers are a real shitshow to deal with. First you need a Mux to deal with USB-C's two way insertion, so your signals wont get flipped. Next thing is that you have four lanes at your disposal in alt mode. Which you can either use for four Display Port Lanes or two DP lanes and two USB 3.0 lanes. (You always get USB 2.0) Now you may think that there would be one simple chip to do it all? Nope you need atleast two at the price of 6$ each. One for PD and one for Alt modes. Both are very hard to solder (QFN, 0.5 mm pitch 40+ pins) TI ended up being the only one with a decent offering of IC's that do what I need. As for working with them, you would think that you just slap a simple MCU on there that communicates over I2C or SPI to configure the chips? Nope! You program the chips memory from which it configures itsself. And the programming is done with some TI tool which gives me no idea as to how you can handle everything whith no control logic behind it.
Looking into alternative IC's leaves me with cypress semi. And their documentation is basically a total mess. I wanna know what that chip is good for and what I need to do to make it work. I dont care about technical details mixed with marketing jargon nobody understands. And I really despise that I have to register just to download a datasheet. Especially since there is no info about it on the main page.
And this whole rant hasnt even touched the topic that USB-C only uses DP and nothing else. So you better hope that you have DP++ so you can use a passive conversion.
This was my Ted Talk about USB-C. Some info in it may be subject to my stupidity and errors as it currently is 02:15 in the morning and I need some sleep.14 -
Everywhere you go, you find these memes where developers are skeptical of their work. Things like "It works. I don't know how. It doesn't work. I don't know how.". Don't you guys think this is a huge problem? And people say that their programming language is the best, because preference. But isn't this happening because our tools suck?
Yes the problems maybe inherently complex but at least we should be able to figure out the logic behind the snipper and reason about it.
Haven't really experienced it, but they say Haskell and the likes are great at this and it must be true because it's backed by mathematical properties and laws, not " experience".
So the rant here is, wish we had better tools in the mainstream that allowed us to enjoy absolute faith in at least what we have written, regardless of the fact that we understood the problem in the domain.11 -
First year: intro to programming, basic data structures and algos, parallel programming, databases and a project to finish it. Homework should be kept track of via some version control. Should also be some calculus and linear algebra.
Second year:
Introduce more complex subjects such as programming paradigms, compilers and language theory, low level programming + logic design + basic processor design, logic for system verification, statistics and graph theory. Should also be a project with a company.
Year three:
Advanced algos, datastructures and algorithm analysis. Intro to Computer and data security. Optional courses in graphics programming, machine learning, compilers and automata, embedded systems etc. ends with a big project that goes in depth into a CS subject, not a regular software project in java basically.4 -

Mentors, take note. This is a best practice over here.
I've spent two days digging through obscure documentation trying to accomplish one of those tasks that is simple in word and complex in deed. Namely, I wanted to concatenate (not delete) near-duplicate values in Pandas before rendering the data into a graph. Two days beating my head against the wall.
One of my mentors (I'm an intern) heard about the issue, wrote in the proper line (a very specifically and archaically formatted command), and pushed it to repo without even asking for thanks. Works like a charm and he saved my rear end. What a guy.
Please, mentors, don't leave your interns hanging on problems where the only solution is shrouded in dubious documentation and magic syntax. Especially when there's a deadline involved. Let them struggle on logic flow and writing good code.
Be like this guy. You'll build the importance of teamwork and your intern will think you're a wizard.2 -
I was absolutely angry, my ego had been wounded. I had built the entire product from scratch, while my bosses just clinged onto one feature that i had not done.
It wasn't even going to be used i knew that and hence was slack. It also required a lot of algo writing.
Post the discussion i decided I'm gonna take out my hurt ego's anger on this algo. I drank whole night and coded. Damn fucking one of the most complex logics i had ever written. It was done and tested while the sun rose. And i slept, next day was a Sunday. I couldn't get hungover.
I was wrong, the logic was used and is one of the core logics of the product. Something that we boast of. 😁rant whiskey algo strikes again algorithm ego wk116 drunk coding algorithms egoistic-devs egotistical -
Ah, developers, the unsung heroes of caffeine-fueled coding marathons and keyboard clacking symphonies! These mystical beings have a way of turning coffee and pizza into lines of code that somehow make the world go 'round.
Have you ever seen a developer in their natural habitat? They huddle in dimly lit rooms, surrounded by monitors glowing like magic crystals. Their battle cries of "It works on my machine!" echo through the corridors, as they summon the mighty powers of Stack Overflow and Google to conquer bugs and errors.
And let's talk about the coffee addiction – it's like they believe caffeine is the elixir of code immortality. The way they guard their mugs, you'd think it's the Holy Grail. In fact, a developer without coffee is like a computer without RAM – it just doesn't function properly.
But don't let their nerdy exteriors fool you. Deep down, they're dreamers. They dream of a world where every line of code is bug-free and every user is happy. A world where the boss understands what "just one more line of code" really means.
Speaking of bosses, developers have a unique ability to turn simple requests into complex projects. "Can you make a small tweak?" the boss asks innocently. And the developer replies, "Sure, it's just a minor change," while mentally calculating the time it'll take and the potential for scope creep.
Let's not forget their passion for acronyms. TLA (Three-Letter Acronym) is their second language. API, CSS, HTML, PHP, SQL... it's like they're playing a never-ending game of Scrabble with abbreviations.
And documentation? Well, that's their arch-nemesis. It's as if writing clear instructions is harder than debugging quantum mechanics. "The code is self-explanatory," they claim, leaving everyone else scratching their heads.
In the end, developers are a quirky bunch, but we love them for it. Their quirks and peculiarities are what make them the creative, brilliant minds that power our digital world. So here's to developers, the masters of logic and the wizards of the virtual realm!13 -
We had 1 Android app to be developed for charity org for data collection for ground water level increase competition among villages.
Initial scope was very small & feasible. Around 10 forms with 3-4 fields in each to be developed in 2 months (1 for dev, 1 for testing). There was a prod version which had similar forms with no validations etc.
We had received prod source, which was total junk. No KT was given.
In existing source, spelling mistakes were there in the era of spell/grammar checking tools.
There were rural names of classes, variables in regional language in English letters & that regional language is somewhat known to some developers but even they don't know those rural names' meanings. This costed us at great length in visualizing data flow between entities. Even Google translate wasn't reliable for this language due to low Internet penetration in that language region.
OOP wasn't followed, so at 10 places exact same code exists. If error or bug needed to be fixed it had to be fixed at all those 10 places.
No foreign key relationships was there in database while actually there were logical relations among different entites.
No created, updated timestamps in records at app side to have audit trail.
Small part of that existing source was quite good with Fragments, MVP etc. while other part was ancient Activities with business logic.
We have to support Android 4.0 to 9.0 of many screen sizes & resolutions without any target devices issued to us by the client.
Then Corona lockdown happened & during that suddenly client side professionals became over efficient.
Client started adding requirements like very complex validation which has inter-entity dependencies. Then they started filing bugs from prod version on us.
Let's come to the developers' expertise,
2 developers with 8+ years of experience & they're not knowing how to resolve conflicts in git merge which were created by them only due to not following git best practice for coding like only appending new implementation in existing classes for easy auto merge etc.
They are thinking like handling click events is called development.
They don't want to think about OOP, well structured code. They don't want to re-use code mostly & when they copy paste, they think it's called re-use.
They wanted to follow old school Java development in memory scarce Android app life cycle in end user phone. They don't understand memory leaks, even though it's pin pointed by memory leak detection tools (Leak canary etc.).
Now 3.5 months are over, that competition was called off for this year due to Corona & development is still ongoing.
We are nowhere close to completion even for initial internal QA round.
On top of this, nothing is billable so it's like financial suicide.
Remember whatever said here is only 10% of what is faced.

There was a task of fixing up a payments page that features pretty complex logic. Initially it was like 200 lines of code, seems short but it was a fucking spaghetti mess. Never seen more cognitively complex code in my life.
So I delete the spaghetti and pull out the 500 lines fucking state machine. It works perfectly. It’s perfectly understandable even though it’s longer.
This is how I deal with problems. Shorter code isn’t always better code.4 -
TIL how time-delay relays are used in circuits with a hell lot of power. For example to power and control the motor of a machine that lifts 20 people up to the sky and back to ground again.
FYI this is a simple circuit. We will hopefully start experimenting with SPS/Speicherprogrammierbare Steuerung (Programmable Logic Controllers). I cannot wait to make use of our predesigned circuits with complex logic gates with the new unit we will get to know.
Unfortunately, we will do practical networking (testing cables for the signal strength and speed, building a network of telephones and call each other - guess this is going to be the funniest part lol, etc.) before the SPS and LOGO software phase.
Btw. I am doing an all-nighter rn and repeating everything we did in our recent signal calculation lesson. We have another exam tomorrow.11 -

What are y’all thoughts regarding whitespace, I have a coworker that uses an absurd amount of white space between functions, declaration sections... declarations and logic within functions.... and makes everything very complex without refactoring we talking like 5+ if else inceptions deep.

Below is a transcript from work Slack today. Only the names and some code are changed. It ended up causing a bit of drama. DevRanters, what do you take from this?
---
Delivery Lead:
Hey Gang. What's the blocker for FEATURE-123?
Dev1:
FEATURE-122 crashed on iOS app when viewing Feature Introduction page.
Teach Lead:
I've talked about this with Dev1 on a side channel.
And diagnosed the stack trace.
It looks like there is/was some bad handling of a List in the Feature Introduction view logic.
But this is confined to changes that Dev2 is still working on.
(It's not present in master)
Dev2, what's your current position on this?
Dev2:
I have tested at my end with Dev1 but it seems to be working fine
Tech Lead:
There is a race condition related to the use of someList.first()
My guess is that theres a Flow of those lists defined, with an initial value of emptyList
And that on your machine, that Flow is updating with a new value quickly enough that it doesn't matter.
But on Dev1's, for whatever reason, it doesn't get there in time, hits the empty list and falls over.
The logic that's performing the first() needs to gracefully handle empty lists as well.
Dev2:
Where is that logic called?
Tech Lead:
Here's the stack trace Dev1 provided in our conversation earlier:
Caused by: kotlin.NoSuchElementException: List is empty.
...
at 3 iosApp 0x00000000 kfun:kotlin.NoSuchElementException#<init>(kotlin.String?){} + 00
at 4 iosApp 0x0000000 kfun:kotlin.collections#first@kotlin.collections.List<0:0>(){0§<kotlin.Any?>}0:0 + 000
...
at 9 iosApp 0x0000000 kfun:kotlin.coroutines.native.internal.BaseContinuationImpl#resumeWith(kotlin.Result<kotlin.Any?>){} + 0000
This line:
kfun:kotlin.collections#first@kotlin.collections.List<0:0>()
...says that it's first() being called on an empty list.
Dev1:
FYI: Dev3/Dev4/myself are seeing the same issue with the same stack-trace above.
Tech Lead:
So Dev2, have you introduced such a call?
Because I checked master branch and there isn't one, in that version of the file.
Ok, I'll check your working branch Dev2
...
Yes you have here:
var processed1 = someList.first()
var processed2 = someList.first()
...
Lines 123, 124.
Solution looks really straightforward guys.
Dev2:
Okay, I will fix that and push the change
Tech Lead:
Check if someList is empty and allow for generating / handling null processedValues in the view.
Now; I'm going to be straight with you here.
This issue has been discussed over several hours today.
I expect that either one of you could have gone through the process I did in the last 10 minutes above, and resolved it in the same way :point_up:
Dev2:
I went on a break and it's not reproducible on my machine
Tech Lead:
I didn't reproduce it on mine either.
Dev1:
Dev2 and myself are now on sharing screen to sort this issue out. Hope to update back later.
Tech Lead:
<Screen shot of diff with changed code>
:point_up: That change should do it.
Dev2:
Already have pushed the change.
Tech Lead:
...just seen it, is good - same approach :ok_hand:
Dev1 please let us know when tested on your machine.
Dev1:
That does it. It fixes the issues. Thank you, Dev2. I will pick it off from here.
Tech Lead:
Glad to hear it guys.
Dev1:
I have to say this that it is not because we are not working on the issue - Dev2 and myself (together with Dev3/Dev4) have been on this issue all this morning. It just difficult to connect the dot when it wasn't reproducable on Dev2's machine. I brought the issue up because I wanted to switch to working on other tickets while waiting for this to resolve. Still thank you largely for Dev2's work and your keen eyes that spot and resolve the issue quickly.
Tech Lead:
Noted Dev1.
I think the take-away has to be to read the stack-trace carefully... don't worry - we've all been guilty of not reading the error in full, at some point.
The stack trace said that the 'first' element is being referenced from an empty list - that's just logically impossible, right?
Looking for that call to first, we saw it wasn't in the code before, and is after (two of them, in fact).
So then we ask ourselves, how can we deal with an empty list - and then solution almost presents itself.
It didn't really take reproduction of the error to resolve.
Maybe working with a new tech stack creates an anxiety that every issue faced will have a complex solution related to that stack; but I think you'll agree, this particular issue really just required a deep breath and your trusty 'debugging skills 101'... don't lose them! :smiling_face:4 -
I absolutely hate software to the point where I started converting from sysadmin to becoming more like a dev. That way I could just write my own implementations at will. Easier said than done, that's for sure. And it goes both ways.
I think that in order to be a good dev, you need these skills the most:
- Problem solving skills
- Creativity, you're making stuff
- Logical reasoning
- Connecting the dots
- Reading complex documentation
- Breaking down said documentation
- A strong desire to create order and patterns
- ...
If you don't have the above, you may still be able to become a dev.. but it would be harder for sure, and in some cases acceptance will be lower (seriously, learn to Google!)
One thing I don't think you need in development is mathematics. Sure there's a correlation between it and logic reasoning, but you're not solving big mathematical monsters here. At most you'd probably be dealing with arrays and loops (well.. program logic).
Also, written and spoken English! The language of the internet must be known. If it's not your first language, learn it. All the good (and crucial) documentation out there is in English after all.
One final thing would be security in my opinion, since you're releasing your application to the internet and may even run certain services, and deal with a lot of user data. Making those things secure takes some effort and knowledge on security, but it's so worth it. At the most basic level, it requires a certain mindset: "how would I break this thing I just made?"4 -
I hate complex boolean logic.
(true||false) && true || false || (true && false) ... etc (continue for at least ten clauses four times as long)10 -
Disclaimer - Day in the life of a whitehat student.
Whitehat Whitehat Whitehat
What is this????
When I attended my first white hat jr online free trial class, I got to know that the teachers does not know the difference between java and javascript. Infact they were saying blockly as javascript. I was knowing the difference between the same. There were 3 types of courses -
***Note : - This information is taken from the whitehat official website***
1.) Introduction to Coding :-
Sequence, Fundamentals Coding Blocks, Loops
(Teach us to drag and drop blocks of code.org(blockly))
2.) App Developer Certificate:-
Events / UI,Conditionals, Complex Loop, Logic Structures, Turtle Coding
(Advanced drag and drop(blockly))
3.) Advance Coding with Space Tech -
Extended UI/UX, Rich GUI app, Space Tech simulation in Space Lab / Game Lab, Professional Game Design.
(GUI - with tkinter(python), Game Design - Blockly(code.org))
These things are rubbish ......making GUI's is simplest with tkinter and the students who make games (with code.org) submit their codes to the whitehat community (because the teacher says "they will compile it to an android app, then you can publish it to playstore" --- this is for 1% students who are able to design their own games).
The thing whitehat do with code given by 1% best students:-
Export to HTML from code.org
Download HTML to APK Convertor
Setup SDK
Successfully converted to APK!
Publish it to Whitehat Jr console account
Credits of the students
Income of the exporters
Rest all students will only think to be the CEO of google one day.
My Opinion - StackOverflow, Unity for Game Development, Android Studio, Dart, Flutter and Kivy (using google colab for compiling the python code to an apk) for app development and Flask, HTML, CSS for web development.7 -
can we just get rid of floating points? or at least make it quite clear that they are almost certainly not to be used.
yes, they have some interesting properties that make them good for special tasks like raytracing and very special forms of math. but for most stuff, storing as much smaller increments and dividing at the end (ie. don't store money as 23.45. store as 2,345. the math is the same. implement display logic when showing it.) works for almost all tasks.
floating point math is broken! and most people who really, truely actually need it can explain why, which bits do what, and how to avoid rounding errors or why they are not significant to their task.
or better yet can we design a standard complex number system to handle repeating divisions and then it won't be an issue?
footnote: (I may not be perfectly accurate here. please correct if you know more)
much like 1/3 (0.3333333...) in base 10 repeats forever, that happens with 0.1 in base 2 because of how floats store things.
this, among other reasons, is why 0.1+0.2 returns 0.300000046 -
Started taking an Angular 5 tutorial to see how things were going in the world of Angular JS. I got to say, I am impressed. It makes me think of React in a lot of ways, but with a heavy emphasis on separation of concerns. Particularly suited for those that do not like to mix views with logic. I am liking it and going at it with an open mind although React is still my preferred option. One thing that irritates me is the ammount of "plz sir, can you give code for <insert complex and heavy app that people just do not give for free>".....so annoying.
On another note, I like how Angular brings in the concept of di among other things to the table, what I am trying to get is the feeling of writing 2 apps, there is one thing to have MVC on the background, the other is to have it in the frontend! Oh well, Angular (first edition) was fun and I know it decently well, time to get cracking on more code!! -
To create an abstraction simple enough to make complex business logic challenges solvable for non programmers.
The issue I see today is programmers solving problems they don't understand as well as the user. I think two ways might be taken:
- Programmers specialize in other fields and solve problems there
- Other professionals create their own software
Both will happen in the future (IMHO) and I want to help the second happening.
Note: Excel does this really well, but I think we can so quite better today.2 -
God I'm getting tired of the whole TDD culture. I get it, testing is good, but we're getting to the point where several major OSS projects fail on common real-world use cases because instead of worrying about the main purpose of a software, devs only worry about satisfying their artificial tests. And when someone opens an issue, it just stays there for months or even years simply because setup & teardown logic for the required tests would be several times more complex than the actual fix.11

Alright, fellow coders, I need your help this time <3
I was thinking about getting a full stack developer position after school, with mean/mern stack. (Yes, I love js, but you can hate me for that later)
So, I just got an offer for a front-end developer position that I didn't apply to but was recommended for by my full stack prof.
Everything is great about that company, but! I'm not sure I'm good for that!
My question is: does being a front-end developer mean being good at putting together nice looking website?
I'm good with angular, but suck at material or just CSS in general.
I can implement business logic, but anything more complex than grids causes my eye to twitch.
So, is front-end developer supposed to be good at design part of it or not?
Google says yes, but I got other opinions from my friends, but they are still students too!
All hope on you guys! Thank you8 -
Gonna teach someone conpletely new to programming some C#. What are some good exercises I can give them to understand general programming well?
So far I'm thinking FizzBuzz, some progressively more complex math+logic stuff and maybe fibonacci using recursion.11 -
1. Find a function: getDayDiff(d1, d2)
2. d1 and d2 are momentjs dates.
3. See that function performs complex ancient math rituals and then returns an integer
4. Try to rewrite function, return d2.diff(d1, 'days')
5. Should be OK right? Run tests
6. Whole module melts down. WTF?!
Turns out the math performed returned the difference + 1 because it included the current day which moment's diff() function does not (out of the box).
Processes that depended on this function then uses the result like this:
const diff = getDayDiff(d1, d2)
if (diff-1 == should_match) { /* more fun logic */ }
$ git checkout .

I would have liked to complete a task this week, however the one thing I've been working on has it's requirements changed every time I finish.
I get that things change, but all of this extra logic is far too complex for the issue at hand, and I don't have time to do other assigned things due to how laborious and intensive testing for this part of the application is.rant clients changing requirements there are only so many hours in the day don't blame me if other things are delayed -
How do you deal with relatively complex Boolean logic requirements?
Here's a simple example, of which I missed 50% of the cases because it was non-intuitive to me:
A year is a leap year if:
- it is divisible by 4
- except it is also divisible by 100
- unless it is also divisible by 400
To my intuition, the logic tree is as follows:
if (year % 4 == 0) -> true
if (year % 100 == 0) -> false
if (year % 400 == 0) -> true
so I ended up with 3 cases and I initially missed all the others until I started coding.
The full solution is:
if(year % 4 === 0) {
if(year % 100 === 0) {
if(year % 400 === 0) {
true
} else {
false
}
false
} else {
true
}
true
} else {
false
}
}
I don't like it when I don't immediately see all logic paths.19 -
we have 4 options when come to Windows 10 development
+ Windows 32 API
+ WPF
+ WinForm
+ UWP
the best performance would be Windows 32 API but really painful when maintaining
but game like League Of Legends have complex logic still accomplish so I think they also create their own OOP pattern7 -
Who actually started the reign of mixed character passwords? because seriously it sucks to have an unnecessarily complex password! Like websites and apps requesting passwords to contain Upper/Lower case letter, numeric characters and symbols without considering the average user with low memory threshold (i.e; Me).
Let's push the complaint aside and return back to the actual reason a complex password is required.
Like we already know; Passwords are made complex so it can't be easily guessed by password crackers used by hackers and the primary reason behind adding symbols and numbers in a password is simply to create a stretch for possible outcome of guesses.
Now let's take a look into the logic behind a password cracker.
To hack a password,
1) The Password Cracker will usually lookup a dictionary of passwords (This point is very necessary for any possible outcome).
2) Attempts to login multiple times with list of passwords found (In most cases successful entries are found for passwords less than 8 chars).
3) If none was successful after the end of the dictionary, the cracker formulates each password on the dictionary to match popular standards of most website (i.e; First letter uppercase, a number at the end followed by a symbol. Thanks to those websites!)
4) If any password was successful, the cracker adds them to a new dictionary called a "pattern builder list" (This gives the cracker an upper edge on that specific platform because most websites forces a specific password pattern anyway)
In comparison:
>> Mygirlfriend98##
would be cracked faster compared to
>> iloveburberryihatepeanuts
Why?
Because the former is short and follows a popular pattern.
In reality, password crackers don't specifically care about Upper-Lowercase-Number-Symbol bullshit! They care more about the length of the password, the pattern of the password and formerly used entries (either from keyloggers or from previously hacked passwords).
So the need for requesting a humanly complex password is totally unnecessary because it's a bot that is being dealt with not another human.
My devrant password is a short story of *how I met first girlfriend* Goodluck to a password cracker!6 -
If you find a programmer that uses getters() and setters() without any complex logic inside them, you should burn him/her/whatev with the strength of a thousand suns.19

Recently I have had to help our support team handle a variety of embedded development support tickets for a product line that is quite complex in nature. It is really starting become frustrating how common it is that the so-called “developers” that are using this product are so incompetent at requesting help in a proper/sane way. It is even more frustrating that some of these schmucks start acting up and stating bullshit statements like (para-phrasing) “OMG we have a ‘big opportunity’ and a deadline to meet”, “you need to help us faster”. These are also the same guys that are like “I know you have a free SDK that does everything correctly, but I want to write my own ‘pro’ driver written in my own ‘dumbass code style’. Oh and I am not going to follow documentation and not implement required functions and make you read my god awful code snippets to find out what I what I did wrong instead of reading the docs or comparing against the SDK.”
To anyone that behaves this way...fuck you! Just stop. Stop being a developer altogether. If your “opportunity” is so important, why the fuck are you half-assing your support ticket? Why are you making it SO DAMN DIFFICULT for someone to help support you! Give as much info as possible to prove your point or provide context to the problem you are having. In the majority of these tickets the dumbasses don’t even consider that relaying the product’s firmware version is relevant information, that a Wireshark (and/or logic analyzer) capture can be very useful to provide context to the type of operation being performed. Code snippets can be nice but only if there is sufficient context. We have had to ask one guy 3 times already for the FW version...what the flipping hell is wrong with you?!
Ug...I feel sorry for Support/FAEs sometimes dealing with customer bullshit drives me nuts and its a shame this stuff happens in a sector that should know better...Please don’t be like these devs. If you make a half-assed request it is only reasonable to expect a half-assed response and nothing more. -
That feeling when you inherit a script to automate something that takes 10 seconds. Why would they even write this? It's not like the task is hard....
...
And why would they write it this way? I'm sure if I just move this part and ....
That feeling when you spend several hours improving and redesigning a perfectly functional script to automate a 10 second task for zero gain aside from cleaner code. "But the code for this quick-and-dirty script I'm never going to look at again looks so much better now!"
... If only it did a bunch of complicated parsing, regex matching, and error checking just so I can answer one less prompt.... Unless that parsing fails. Then it should still ask me for that prompt... And also validate that the answers I give are valid and correct....
That feeling when you spend a whole nother day starting from scratch to implement error checking and complex parsing logic knowing full well the original task takes 10 seconds to do manually and is needed at most twice a day (for a grand total of 20s a day)
WHY AM I LIKE THIS?!?!?!4 -
In reply to this:
https://devrant.com/rants/260590/...
As a senior dev for over 13 years, I will break you point by point in the most realistic way, so you don't get in troubles for following internet boring paternal advices.
1) False. Being go-ahead, pro active and prone to learn is a good thing in most places.
This doesn't mean being an entitled asshole, but standing for yourself (don't get put down and used to do shit for others, or it will become the routine) and show good learning and exploration skills will definitely put you under a good light.
2)False. 2 things to check:
a) if the guy over you is an entitled asshole who thinkg you're going to steal his job and will try to sabotage you or not answer acting annoyed, or if it's a cool guy.
Choose wisely your questions and put them all togheter. Don't be that guy that fires questions in crumbles, one every 2 minutes.
Put them togheter and try to work out the obvious and what can be done through google or chatgpt by yourself. Then collect the hard ones for the experienced guy and ask them all at once. He's been put over you to help you.
3) Idiotic. NO.
Working code = good code. It's always been like this.
If you follow this idiotic advice you will annoy everyone.
The thing about renaming variables and crap it's called a standard. Most company will have a document with one if there is a need to follow it.
What remains are common programming conventions that everyone mostly follows.
Else you'll end up getting crazy at all the rules and small conventions and will start to do messy hot spaghetti code filled with syntactic sugar that no one likes, included yourself.
4)LMAO.
This mostly never happens (seniors send to juniors) in real life.
But it happens on the other side (junior code gets reviewed).
He must either be a crap programmer or stopped learning years ago(?)
5) This is absolutely true.
Programming is not a forgiving job if you're not honest.
Covering up mess in programming is mostly impossible, expecially when git and all that stuff with your name on it came out.
Be honest, admit your faults, ask if not sure.
Code is code, if it's wrong it won't work magically and sooner or later it will fire back.
6)Somewhat true, but it all depends on the deadline you're given and the complexity of the logic to be implemented.
If very complex you have to divide an conquer (usually)
7)LMAO, this one might be true for multi billionaire companies with thousand of employees.
Normal companies rarely do that because it's a waste of time. They pass knowledge by word or with concise documentation that later gets explained by seniors or TL's to the devs.
Try following this and as a junior:
1) you will have written shit docs and wasted time
2) you will come up to the devs at the deadline with half of the code done and them saying wtf who told you to do that
8) See? What an oxymoron ahahah
Look at point 3 of this guy than re-read this.
This alone should prove you that I'm right for everything else.
9) Half true.
Watch your ass. You need to understand what you're going to put yourself into.
If it's some unknown deep sea shit, with no documentations whatsoever you will end up with a sore ass and pulling your hair finding crumbles of code that make that unknown thing work.
Believe me and not him.
I have been there. To say one, I've been doing some high level project for using powerful RFID reading antennas for doing large warehouse inventory with high speed (instead of counting manually or scanning pieces, the put rfid tags inside the boxes and pass a scanner between shelves, reading all the inventory).
I had to deal with all the RFID protocol, the math behind radio waves (yes, knowing it will let you configure them more efficently and avoid conflicts), know a whole new SDK from them I've never used again (useless knowledge = time wasted and no resume worthy material for your next job) and so on.
It was a grueling, hair pulling, horrible experience that brought me nothing in return execpt the skill of accepting and embracing the pain of such experiences.
And I can go on with other stories. Horror Stories.
If it's something that is doable but it's complex, hard or just interesting, go for it. Expecially if the tech involved is something marketable.
10) Yes, and you can't stop learning, expecially now that AI will start to cover more and more of our work.4 -
So I've been working with a Ruby DSL my colleague wrote for our rails app that builds app flows represented by data using migrations, which are consumed and rendered by the frontend. So data-driven UI.
It's very solid in prod, so we're running with it, but it can be hard to work with because everything is built using migrations - for example, the one signup flow we have spans across 7 migrations that add/change/remove components in the flow, change decision logic, etc.
I'm building a particularly complex one and can't decide which development method is better. I can either
1. write the flow in one huge migration, then change as needed - keep rolling back, resetting and testing until it works, or
2. increment changes and additions in multiple migrations across multiple pull requests, such that the final product spans across about 10-12 smaller migrations
Which one?
Both are super icky to me but I'm leaning toward 1. At least all of the shit would be in one place and would make sense without needing to switch between 10-12 files to see where shit is being defined, changed, etc. because it reads chronologically.3 -
I was talking to some post doc researchers today about a complex logic problem and a fresher interrupted and said, I think you can do that with objects... (The logic problem didn't depend on how the solution is modelled)

Once a React aficionado, twice the frustration we endure,
In the realm of libraries, React's problems seem impure.
With Svelte's elegance and grace in our sight,
Let's vent about React, as day turns into night.
Boilerplate Overload, a monotonous affair,
Classes, constructors, lifecycle steps we declare.
In Svelte's simplicity, we find a breath of fresh air,
Just markup and magic – a coder's love affair.
Complex State Management, React's Achilles' heel,
Redux, Mobx, and their massive code appeal.
Svelte's state handling is a cinch, for real,
No more tangled webs of logic to conceal.
Unnecessary Re-Renders, React's performance woe,
Countless updates, like a never-ending show.
Svelte updates what's needed, like a pro,
Efficiency and speed, in its radiant glow.
Verbose Syntax, JSX's verbosity on display,
HTML in JavaScript, causing dismay.
Svelte's concise template syntax lights our way,
No more endless tags, just code that's here to stay.
Lack of Truly Reactive Behavior, React's hurdle high,
Hooks to wrangle, state to satisfy.
Svelte's reactivity, no need to question why,
It just works, oh my, oh my.
Ecosystem Complexity, React's sprawling sprawl,
Choices galore, making us bawl.
In Svelte's world, simplicity is the call,
A coherent ecosystem, it has it all.
Learning Curve, React's mountain to climb,
Classes, hooks, context, a hill of time.
Svelte's gentle curve feels sublime,
A smoother path to code, so fine.
Tooling Overkill, React's complex array,
Build tools, linters, configs in disarray.
Svelte's streamlined setup leads the way,
No more intergalactic code buffet.
Debugging Headaches, React's mysterious realm,
Complex state, intricate components overwhelm.
Svelte's predictable model, a soothing helm,
Debugging becomes a peaceful realm.
In the end, React, a complex labyrinth we explore,
Svelte's elegance and simplicity we adore.
If only React could learn, its problems to deplore,
A brighter future, for React we'd implore.3 -
