I know a guy who writes everything in Haskell.
He started learning it because his parents got him into a math school (and math schools in Russia use either Python or Haskell), he liked it, but later he dropped out. Today, apart from Haskell, he only really knows HTML and CSS, and maybe some JavaScript.
He writes backend AND frontend in Haskell and uses some kind of JRPC stuff to manage all that. He told me that his life is a pure heaven. He IS RELEVANT (!!!!!!), his apps always run without bugs (because in Haskell you can mathematically prove that there are no bugs), they are performant, faster than C (because you can't write a complex enough app in C that will be as efficient as compiled Haskell, because it's you vs compiler). He doesn't have any problems in life whatsoever. He never got burned out, he never got anxiety or depression. He doesn't act pretentiously and stuff, he's just a normal person who rarely even mentions that he can program.
Science says it can't be done! You can't only know Haskell and be a relevant software engineer! You know what, he didn't _know_ it was impossible. He's like that grandpa from a meme, he got Alzheimers, but because of it he forgot that he had Alzheimers, and now remembers everything.
The fun thing is that he looks like a typical gopnik, with adidas suits and stuff.
What a gem of a person.26 -
Python: I hate the way it uses True/False over true/false
Java: Static. Just fuck static. oh and System.out.println(), why the fuck did they make the basic print function so long to write.
C#: I despise the way the curly braces get automatically put under the function declaration rather than beside it since it's a language style thing.
C: the inability to declare vars in altho declaration of a forloop. Although I think C11 let's you do this.
Javascript: Fucking prototypes.
Coldfusion: it runs like an elephant. Slow and heavy.
Go: The way the compiler won't let you have unused variables/imports. Pain in the ass for testing.17 -
brain: ABSTRACTION ABSTRACTION ABSTRACTION too much ABSTRACTION!
me: jeez calm down a lil i just deployed a boilerplate ember web app with cli tools with next to nothing amount of 'my' code.
b: YES U SUCKER THAT'S WHAT WENT WRONG U DON'T KNOW SHIT ABOUT THE LIL STUFF THAT HAPPENS BEHIND THE SCENES THE FUCK MAN U CALL YOURSELF A CS STUDENT YOU CAN'T EVEN WRITE A COMPILER YET
m: sooo remember when we were studying logic gates and binary conversions and you sigkilled all my threads cuz it was 'boring'?
b: why yes why do you ask
m: WELL that's where we'll end up again if you don't stop nagging me about going down. Trust me, I KNOW how to starve you and you'll beg me to use Python again. You start making advanced data structures in C and the next thing you know you're writing assembly code 'just for fun'.
I have a hackathon coming right up and I have to use a framework or my team loses the advantage. Are we good?
b: well if you put it that way...BUT AFTER THAT YOU'RE TAKING ME TO AN ALGORITHM SESSION
m: *eerily stares at the dusty book in the corner*
you... have a deal3 -
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 -
My two cent: Java is fucking terrible for computer science. Why the fuck would you teach somebody such a verbose language with so many unwritten rules?
If you really want your students to learn about computer, why not C? Java has no pointer, no passed by reference, no memory management, a lots of obscure classes structure and design pattern, this shit is garbage. The student will almost never has contact with the compiler, many don't even know of existence of a compiler.
Java is so enterprise focused and just fucked up for educating purpose. And I say it as somebody who (still) uses it as main language.
If you want your students to be productive and learn about software engineering, why not Python? Things are simple in Python can can be done way easier without students becoming code monkeys (assuming they don't use for each task a whole library). I mean java takes who god damn class and an explicitly declared entry point which is btw. fucking verbose to print something into the console.
Fuck Java.17 -
I believe it is really useful because all of the elements of discipline and perseverance that are required to be effective in the workforce will be tested in one way or another by a higher learning institution. Getting my degree made me little more tolerant of other people and the idea of working with others, it also exposed me to a lot of topics that I was otherwise uninterested and ended up loving. For example, prior to going into uni I was a firm believer that I could and was going to learn all regarding web dev by maaaaaself without the need of a school. I wasn't wrong. And most of you wouldn't be wrong. Buuuuuut what I didn't know is how interesting compiler design was, how systems level development was etc etc. School exposed me to many topics that would have taken me time to get to them otherwise and not just on CS, but on many other fields.
I honestly believe that deciding to NOT go to school and perpetuating the idea that school is not needed in the field of software development ultimately harms our field by making it look like a trade.
Pffft you don't need to pay Johnny his $50dllrs an hour rate! They don't need school to learn that shit! Anyone can do it give him 9.50 and call it a day!<------- that is shit i have heard before.
I also believe that it is funny that people tend to believe that the idea of self learning will put you above and beyond a graduate as if the notion of self learning was sort of a mutually exclusive deal. I mean, congrats on learning about if statements man! I had to spend time out of class self learning discrete math and relearning everything regarding calculus and literally every math topic under the sun(my CS degree was very math oriented) while simultaneously applying those concepts in mathematica, r, python ,Java and cpp as well as making sure our shit lil OS emulation(in C why thank you) worked! Oh and what's that? We have that for next week?
Mind you, I did this while I was already being employed as a web and mobile developer.
Which btw, make sure you don't go to a shit school. ;) it does help in regards to learning the goood shit.7 -
Coming back to c++ after far too long in python...
Compiler: "Do you even know what a semicolon is?!"6 -
Chased a bug for nearly a week. Huge code base, over 2mn lines consisting of a mess of C++, Python and Lua glued together.. Wrote a very complex distributed computational framework. End up with a elusive compiler bug in GCC.. FML

A bit confused
I have a code and it is giving different answers in different language and compilers
the code is
Int a=4
Int b = ++a + a++ + --a
Please ignore the syntactical errors
But this logic give different answers in different compiler and language like in
C(turbo c++ compiler) it gives 12
C(gcc)- 16
Java- 15
Python- 12
Can anybody explain the logic behind this...10 -
Oh god, structure alignement, why you do this... You might be interested if you do C/C++ but haven't tried passing structures as binary to other programs.
Just started working recently with a lib that's only a DLL and a header file that doesn't compile. So using python I was able to use the DLL and redefined all of the structures using ctypes, and the nice thing is: it works.
But I spent the whole afternoon debugging why the data in my structures was incoherent. After much cussing, I figured out that the DLL was compiled with 2 bytes packing...
Packing refers to how structures don't just have all the data placed next to each other in a buffer. Instead, the standard way a compiler will allocate memory for a structure is to ensure that for each field of the structure, the offset between the pointer to the structure and the one to the field in that structure is a multiple of either the size of the field, or the size of the processor's words. That means that typically, you'll find that in a structure containing a char and a long, allocated at pointer p, the double will be starting at p+4 instead of the p+1 you might assume.
With most compilers, on most architectures, you still have the option to force an other alignment for your structures. Well that was the case here, with a single pragma hidden in a sea of ifdefs... Man that took some time to debug...2 -
Yocto is the most overly complicated shit on earth! How the fuck did i ever get my board to boot? You get so easily lost in layers and bb and bbappend and there are like 20 flavours of assignement operators and to configure the kernel you need to run one command for menuconfig and then another right after to pull a diff out of the .config into your project. otherwise noone else will have your changes. TrY the same thing with the bootloader and the whole thing shits its pants. Also there are like four devicetree that are required for boot. And if you specially fuck up here, your hardware will be an expensive paperweight. Also there are like featuresets that enable shizz like wayland or ethernet but good luck finding out what in the actual genderbent jesus the thing you just configured does. And there is like no way to visualize any of it as its just a cockblock of text and files. Also if you use search the results are most likely useless. As the thing you are looking for is a filename and vscode does a text search only. Also you can add layers but whatever the fuck that means as a bsp is like a layer but so can also be a kernel patch or some rando variable change. And good luck fugurig out to which dir $PWD points to. As it could just be on the Elon Musk nazi base on the dark side of the moon. Also every folder starts with meta for some dumb reason. And if it starts compiling you could just aswell build a coffin and go into winter hibernation. It takes fucking forever. I have a 3800x and the build takes 1.5h. Why? Because, BECAUSE, B E C A USE! There is a require package called optee. Which need a python package. That package depends on a crypto lib thats written in rust. And since its all from source, it downloads the FUCKING rust compiler source and compiles the compiler to compile a lib that only takes like 5 seconds to compile. Also good luck figuring that out without constantly staring at the compile log. As there is some compilation time info but you need to write a parser for that first as there is no included anal -lyzing tool for it. I could keep on yappin' waaay longer about why dantes inferno is kindergarten compared to yocto, but i dont have enough alcohol in the house to fuel that.1

Friend of mine has some C++ he wrote and wants to run it in a web area, so he can demo it and output the results to a webpage. He wants to stick to using the C++ and avoid rewriting it in Python (my suggestion).
Any advice on how he could go about it? I’ve heard about a C compiler that could run in a web area, but not sure if they are any good..?4 -
I had an introductory course on C during my engineering (using the Turbo C compiler). Got interested there and started learning on my own during the breaks between semesters. Mainly ended up doing basic things with VB 6, C, C++ and some Windows programming using a language called BCX Basic.
Then ended up being introduced to HTML, JavaScript and Java during my first job and ABAP in the next. Also managed to learn a little of Python in my spare time (weekends) along the way.
I still continue learning the basics of new languages in my spare time (planning to start with PHP next). -
Fuck you Linux! I thought user password validation would be a piece of cake, like bash one liner. How wrong could I be!
Yeah, it's already ugly to grep hash and salt from /etc/shadow, but I could accept that. But then give me a friggin' tool to generate the hash. And of course the distro I chose has the wrong makepswd, OpenSSL is too old to have the new SHA-512 built in, as it should be a minimal installation I don't want to use perl or python...
And the stupid crypto function that would do me the job is even included in glibc. So it's only one line of C-code to give me all I want, but there is no package that would provide me this dull binary? Instead I will have to compile it myself and then again remove the compiler to keep image small?5
