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 -
Please actually pay attention to compiler warnings. They exist for a reason beyond just being a nuisance. If you're willingly ignoring warnings then you're accepting unnecessary risk into your project.4

I propose that the study of Rust and therefore the application of said programming language and all of the technology that compromises it should be made because the language is actually really fucking good. Reading and studying how it manages to manipulate and otherwise use memory without a garbage collector is something to be admired, illuminating in its own accord.
BUT going for it because it is a "beTter C++" should not constitute a basis for it's study.
Let me expand through anecdotal evidence, which is really not to be taken seriously, but at the same time what I am using for my reasoning behind this, please feel free to correct me if I am wrong, for I am a software engineer yes, I do have academic training through a B.S in Computer Science yes, BUT my professional life has been solely dedicated to web development, which admittedly I do not go on about technical details of it with you all because: I am not allowed to(1) and (2)it is better for me to bitch and shit over other petty development related details.
Anecdotal and otherwise non statistically supported evidence: I have seen many motherfuckers doing shit in both C and C++ that ADMIT not covering their mistakes through the use of a debugger. Mostly because (A) using a debugger and proper IDE is for pendejos and debugging is for putos GDB is too hard and the VS IDE is waaaaaa "I onlLy NeeD Vim" and (B) "If an error would have registered then it would not have compiled no?", thus giving me the idea that the most common occurrences of issues through the use of the C father/son languages come from user error, non formal training in the language and a nice cusp of "fuck it it runs" while leaving all sorts of issues that come from manipulating the realm of the Gods "memory".
EVERY manual, book, coming all the way back to the K&C book talks about memory and the way in which developers of these 2 languages are able to manipulate and work on it. EVERY new standard of the ISO implementation of these languages deals, through community effort or standard documentation about the new items excised through features concerning MODERN (meaning, no, the shit you learned 20 years ago won't fucking cut it) will not cut it.
THUS if your ass is not constantly checking what the scalpel of electrical/circuitry/computational representation of algorithms CONDONES in what you are doing then YOU are the fucking problem.
Rust is thus no different from the original ideas of the developers behind Go when stating that their developers are not efficient enough to deal with X language, Rust protects you, because it knows that you are a fucking moron, so the compiler, advanced, and well made as it is, will give you warnings of your own idiotic tendencies, which would not have been required have you not been.....well....a fucking idiot.
Rust is a good language, but I feel one that came out from the necessity of people writing system level software as a bunch of fucking morons.
This speaks a lot more of our academic endeavors and current documentation than anything else. But to me DEALING with the idea of adapting Rust as a better C++ should come from a different point of view.
Do I agree with Linus's point of view of C++? fuck no, I do not, he is a kernel engineer, a damn good one at that regardless of what Dr. Tanenbaum believes(ed) but not everyone writes kernels, and sometimes that everyone requires OOP and additions to the language that they use. Else I would be a fucking moron for dabbling in the dictionary of languages that I use professionally.
BUT in terms of C++ being unsafe and unsecured and a horrible alternative to Rust I personaly do not believe so. I see it as a powerful white canvas, in which you are able to paint software to the best of your ability WHICH then requires thorough scrutiny from the entire team. NOT a quick replacement for something that protects your from your own stupidity BY impending the use of what are otherwise unknown "safe" features.
To be clear: I am not diminishing Rust as the powerhouse of a language that it is, myself I am quite invested in the language. But instead do not feel the reason/need before articles claiming it as the C++ killer.
I am currently heavily invested in C++ since I am trying a lot of different things for a lot of projects, and have been able to discern multiple pain points and unsafe features. Mainly the reason for this is documentation (your mother knows C++) and tooling, ide support, debugging operations, plethora of resources come from it and I have been able to push out to my secret project a lot of good dealings. WHICH I will eventually replicate with Rust to see the main differences.
Online articles stating that one will delimit or otherwise kill the other is well....wrong to me. And not the proper approach.
Anyways, I like big tits and small waists.14 -
How can I be so fucking stupid?
I was developing and testing a small webserver running on an ESP32.
3 fucking hours were wasted resolving connectivity problems because I did not realize the fucking VPN on my PC was still up thus hiding my ESP32's IP.
How fucking brainless...
I've cie ked everything. Dead flash, wrong offsets, compiler warnings, CPU freq. config...6 -
Coworker: I did not progress much but at least I managed to get rid of all compiler warnings.
Me: That's okay. What were they about?
Coworker: No idea.
Me: How did you get rid of them then??
Coworker: I removed the "Wall" option when I use gcc. -
We need an open-source alternative to stack overflow. They have fucking monopolizing pieces of ratshit admins there and lame ass bots.
I HAD A FUCKING 450 REP :/ and now i have "reached my question limit"
I mean its okay of you want to keep stackoverflow clean , but straight out rejecting the new queries should be against your god damn principles, if those mofos have any!
If it is so easy to downvote and delete a question for the mods, why can't they create a trash site called dump.stackoverflow.com ? whenever a question is not following their stupid guidelines , downvote it to oblivion. After a certain limit, that question goes to dump space where it will be automatically removed after 30 days. Atleast give us 30 fucking days to gather attention of audience !
And how does a question defines someone's character that you downright ban the person from asking new questions? Is there a phd that we should be doing in our mother's womb to get qualified as legitimate question author?
"No questions are stupid" is what we usually hear in our school/college life. And that's a stretch, i agree. Some questions are definitely stupid. But "Your questions are so stupid we are removing you from the site" is the worst possible way to deal with a question asker.
Bloody assholes.
Now, can anyone tell me that if am passing a parcelable list of objects in an intent before starting a new activity, how can i retrieve it in the new activity without getting any kotlin warnings?
The compiler is saying that the data coming via intent is that of list<Type!> aka list of platform type, so how to deal with this warning?15 -
one of my guys decided to start learning c++ for the fun and fuck of it. We do not use c++ for shit (we web developers in this bitch) and he asked me if in the event of him getting completely fucking stuck he could come to me for guidance, I said sure. I do use c++ for personal game projects....it is mostly very bad C until I need c++, it is horrible seriously, I ain't no expert.
He decides to go with the LLVM. Creates a simple hello world app. Runs clang++ main.cpp -o main.
**QUICK PAUSE**
Done, the CLI returns the prompt back to him. He comes and asks me wtf is going on. I check on my machine(Linux based) and do the exact same thing. Executable comes out.
I check back on his windows machine, try typing the same shit. Nada. It does not throw errors or warnings, and the syntax is fucking fine, can't really fuck up c-outing hello fucking world. FUCKING NADA
I couldn't sit down to troubleshoot since it was still working hours, but this shit is haunting me and I am going ballsack crazy knowing that I won't be able to jump at it until tomorrow.
This just makes me dislike c++, i usually never have issues like that, but then again, I use the microsoft compiler (bitch at me all you want, most game developer tutorials etc use that shit, so does the Cherno, its all i know OK????)
I am going to go crazy sdjkfhasdkjlfghlajkhrfvluidefjbhfksjadhjksdsdsjksdjkl11 -
"Reflective" programming...
In almost every other language:
1. obj.GetType().GetProperties()
or
for k, v in pairs(obj) do something end
or
fieldnames(typeof(obj))
or
Object.entries(obj)
2. Enjoy.
In C++: 💀
1. Use the extern keyword to trick compilers into believing some fake objects of your chosen type actually exist.
2. Use the famous C++ type loophole or structured binding to extract fields from your fake objects.
3. Figure out a way to suppress those annoying compiler warnings that were generated because of your how much of a bad practice your code is.
4. Extract type and field names from strings generated by compiler magic (__PRETTY_FUNCTION__, __FUNCSIG__) or from the extremely new feature std::source_location (people hate you because their Windows XP compilers can't handle your code)
5. Realize your code still does not work for classes that have private or protected fields.
6. Decide it's time to become a language lawyer and make OOPers angry by breaking encapsulation and stealing private fields from their classes using explicit template instantiation
7. Realize your code will never work outside of MSVC, GCC or CLANG and will always be reliant on undefined behaviors.
8. Live forever in doubt and fear that new changes to the compiler magic you abused will one day break your code.
9. SUFFER IN HELL as you start getting 5000 lines worth of template errors after switching to a new compiler.13 -
C compiler : you have 27 errors and 35 warnings 😐.
Me : ok let's recompile it.🧐
C compiler : ok! You can go now🤣.4 -
When you're working with an unfamiliar codebase where there are tons and tons of compiler warnings to start with... So of course your latest build-breaking mistakes are completely buried.

Coworker: let's use Result monads in the project so that we're forced to deal with exceptions
Me: okay, sounds great!
Me: *implements Result monads *everywhere**
Coworer: how about we don't use results anymore in half the project? It makes the code look ugly. Let's just use exceptions.
Me: ...
Really? Why in your mind is it okay to only force us to handle a few exceptions and others we can just say fuck it and let them wander around?
Oh you want to use try-catch for these other exceptions.
So now we're back at square one, which is trying to remember/figure out which exceptions any method can throw (since the compiler doesn't do shit, not even warnings), but now we also have inconsistent and much less readable code. Isn't it great?
(╯°□°)╯︵ ┻━┻
I also can't do much about it, because I'm just a fucking intern and I do not want to cause trouble, so I just try to say that I disagree with it in the most polite of ways and that's that.4 -
What we will miss, if he really softens:
In fact, if the reason is stated as "it makes debugging easier", then I fart in your general
direction and call your mother a hamster.
In short: just say NO TO DRUGS, and maybe you won't end up like the Hurd people.
Of course, I'd also suggest that whoever was the genius who thought it was a good idea to read things ONE F*CKING BYTE AT A TIME with system calls for each byte should be retroactively aborted. Who the f*ck does idiotic things like that? How did they not die as babies, considering
that they were likely too stupid to find a tit to suck on?
Gnome seems to be developed by interface nazis, where consistently the excuse for not doing something is not "it's too complicated to do", but "it would confuse users".
I think the stupidity of your post just snuffed out everything
I think the OpenBSD crowd is a bunch of masturbating monkeys, in that they make such a big deal about concentrating on security to the
point where they pretty much admit that nothing else matters to them.
That is either genius, or a seriously diseased mind. - I can't quite tell which.
Christ, people. Learn C, instead of just stringing random characters together until it compiles (with warnings).
"and anybody who thinks that the above is
(a) legible
(b) efficient (even with the magical compiler support)
(c) particularly safe
is just incompetent and out to lunch.
The above code is sh*t, and it generates shit code. It looks bad, and
there's no reason for it."
