Computer Science is not science, and it's not about computers. Got reminded about this gem from MIT the other day

FAANG companies will require 11 rounds of leetcode from you and at least 3 phds in CS, but then will still push React slop to their user as some 300k ARR fake YC startup. How does it happen every time?

Dynamic Arrays in C

Year of Linux desktop will never happen as long as glibc is de-facto standard libc. As far as I know, this regression is wontfix, so many games just won't work anymore. Imagine being a game dev from 5 years ago and making a native Linux version of your game in a good faith, that's 100% a net-negative money-wise, only for it to stop working in a couple years. Backward compatibility on Linux does not exist as far as regular users concerned, and the only way to make software that works in years to come is to make it for Windows, and hopefully let Valve and Wine teams handle the rest.

This guy ported DOOM to his own OS written from scratch, which is free and open source. These are people who keep me wanting to open my code editor and lock tf in.

The answer to this is actually very simple - making production grade GUI applications for Linux is a soul crushing depressing agonizing dogshit experience. People just don't want to deal with it.

OOP people are crazy. They will take the most mundane thing in programming ever - passing arguments to a function, and call it DEPENDENCY INJECTION, and then will sell you books and courses about it.

Hear me out: fast native gui programs that don't ship the browser engine

Today I learned that NixOS has steering committee, elections, and a constitution. A FUCKING CONSTITUTION for a Linux distro. Year of Linux desktop will never happen when people larp the government instead of, I don't know, MAKING THE FUCKING SOFTWARE.

$20/hour job: 5 interview stages, 4 take-home coding tasks and 6 months of talking to hrs of different levels 300k/year job: 10 minutes of vibe-check zoom call (or some back-n-forth in twitter dms), and you get an offer in an hour and all systems access by eod

Veteran game programmers sharing decades of their knowledge for free. It's never been easier to learn programming than in 2025. I think Casey Muratory, Jonathan Blow, and Sean Barrett spearheaded biggest thing in programming education a decade or so ago with their streams

I love this website sometimes

A lot of people think Casey is joking about CSS being harder than ASM. No, it's actually unironically true. Web spec is way more complex than any mainstream ISA you might ever need. If you've mastered the dark corners of flexbox and grid, if you know subtle differences in how browser engines treat font sizes, if you ever worked on reducing CLS and optimizing LCP - x86 assembly will be a piece of cake for you as soon as you learn a little bit of bit math. I swear to you, mental overhead of being closer to the hardware is orders of magnitude lower!

Why corpos can't just write emails like normal people. Just say "oops we fucked up here's your 20% discount for a year we'll work hard to never do that again". But instead you have AI-generated response with "Credit Karma" in the footer

Why does Microsoft bother rewriting its core libs to Rust if all users see is just slow React Native slop anyway?

Real reason - this was not in the sprint, so merging this would not count towards performance review at the end of the quarter.

Modern games are native apps that are being released for like 5+ different platforms, and yet web devs will scream that you absolutely need browsers or you can't be crossplatform. The amount of copium we inhale as an industry is insane

don't worry, it will surely work when they deploy agentic GitHub Search MCP to accelerate the search experience and make it AI-powered and agentic!

People are saying that this particular breakage is not a nofix anymore (I thought it was, initially), but it doesn't undermine anything I said. glibc breaking ABI was an issue since FOREVER. Linus himself called it out many times. And this isn't gonna be the last one!

Jai is officially on github! With syntax highlighting and stuff!

There's a gigachad in Jai beta who wrote a lisp parser that lets you import Lisp files directly as Jai modules. It uses some Jai metaprogramming magic to parse Lisp files at compile time and insert resulting Jai code into the target program.

The stupidest thing about C programming language is that stdint.h wasn't introduced until C99, but even then, Microsoft didn't have it until like 2010. So now Windows has unsigned long as 32 bits, Linux has it as 64 bits, and every C programmer has their own fucking int aliases!

I wanted to counter that Raylib doesn't have software rendering, but holy shit they literally dropped it 3 weeks ago. Very common Raylib W

This is the very original G of the anti-OOP sentiment that I remember seeing just few years after starting my professional programming career. At the time I was very intrigued by it, but my senior peers instantly dismissed it and called it naive and non-scalable. I had pretty much no choice but to listed because, well, I was just a beginner guy who got into enterprise hell and I had no arguments to defend it other than "yeah just writing normal code seems so much easier". I'm really glad that nowadays we mostly left this crazy world of OOP behind, minus some very high paying corners of Enterprise Java (tm) where programmers in their 50es go to die to.

I'm listening to new @cmuratori podcast on IntelliJ channel and this part really highlights my struggle being a Eastern European working for Americans as contractor. Americans have ability to take any combination of letters, even the most innocent, and getting offended at it. I grew up in an environment where giving and taking direct feedback is considered a trait, so it really took me a lot of time to learn "proper" English to navigate American idioms in a way that my colleagues, managers and customers don't feel like I'm constantly being a dick for no reason. It's somewhat funny to see that sometimes it's so ridiculous that Americans themselves are struggling with it :D

I have removed two hash tables and replaced them with static arrays that you preload and then access with enum ints instead of string keys. Feel like a real optimization expert

If your programming language "build system" is not either simple build.bat/build.sh, or a file in the same programming language - you fucked up, your language is bad, throw it away.

Entire software rendering backend of SDL is just a dozen of C files in a single directory. It's never been easier to find information on how to draw stuff on the screen than in 2025. What are you waiting for?

I once quit my job without any plan. And was just doing recreational programming, watching tv shows, hanging with my family, and playing games for 3 months. Best 3 months of my life by far.

When I write win32 code I don't really know why something works as it does. The code is closed, you can't look into win32 api sources. On Linux, you can go all the way down to the kernel and get full context.

A compiler that rolls out a doxing campaign against you every time you use unsafe would be a banger

This is r/speedrun post of all time

One guy single-handedly destroying Perforce, a company that has 1800 employees. I really love version control renaissance we're seeing in 2025, with all major players in the field being heavily challenged.

Pray for me as I'm about to install 5 months of Arch Linux updates...

Yes, absolutely! It's a shame there isn't like a universal C library that's literally just a tiny wrapper around syscalls and people who want to rawdog syscalls have to do their own thing most of the time.

The point of this post is why do you want to hire "the best of the best of the best sir!" if your goal is to ship crap that any 3-weeks bootcamp graduate can do?

I like this mini-argument about unsigned integers in C between @rfleury and PLT people while @EskilSteenberg just casually be like "actually, you should use u32 for array indices, so that when it underflows you're 4 gigs off and more likely to crash" :D

I'm very surprised MS bots are not here in the thread asking you to DM them your issue xdd

BREAKING: git v3.0 will fully replace Perl with Rust

Gamedev and web dev converges in 2025. Using off-the-shelf frameworks just because it lets you hire cheap 3rd world labor is something web shops did since forever. AAA game studios are catching up

Let's talk about security in Rust! Rust compiler has security guarantees that are quite foolproof, so traditional RAII style of programming from C/C++ land becomes very safe by default, posing minimal (realistically, close to 0) risk of causing memory-related security fuckups. And Rust slowly, but steadily gains adoption - you see C/C++-written tools getting rewritten in Rust, or wrapped into safe Rust wrapper, pretty much a few times a day. Now, there are, of course, realistically thinking and reasonable people, who understand that Rust is definitely a net-positive on the system's programming space, and while it has productivity hits, the guarantees it gives might be worth it in the long run in many applications. There are also, of course, terminally online redditors, who see some kind of agenda everywhere they look, but it's just a natural part of Internet being The Place For Everyone (c). Aight, back to the topic! What I don't see people talking about enough is, in my opinion, the biggest security risk in Rust right now, which is the most awful ecosystem hygiene that happened since npm. You see projects that are not even that complex relying on insanely large number of crates. One of my biggest shocks dealing with this was me packaging Alacritty, a relatively featureless terminal emulator, for GNU Guix Linux distro (which is a source-based distro that insists on everything being able to be built from the source down to the lowest possible level). While doing that, I realized that after flattening Alacritty's dependencies there were like 300 3rd party crates it depends on! I don't remember the exact number, it was in 2019-2020, but it was something in a ballpark! And some of these were different versions of same crates due to cyclic dependencies. To my knowledge, the ecosystem isn't much better in 2025. I kid you not, right now there's a leftpad crate that has almost 400k downloads on crates dot io over 9 years. I know, I know `format!` can do the same thing in a built-in way now, it's not the point! The point is that it is only a matter of time before there's a huge-ass supply chain attack scandal in a critical Rust-based project. And remember - Rust is not some punk-ass Javascript that can't do much more than stealing your useless facebook cookies and getting access to your AI-generated boomer slop - because who even runs javascript on the server, can't be me! A Rust code with npm-inspired code ethics will run in some RING 0 kernel space of your enterprise wage overlord's mainframe, making your entire Megacorp Inc. a little bitch of your Overseas Partner. In fact, I wouldn't be surprised if something like this already happens, because there's no way it's humanly possible to vet this many dependencies. Imagine CrowdStrike-tier fiasco, but intentional instead of due to Occam's Razor. I personally think the main reason behind this shitshow is the biggest technical issue with Rust compiler itself - it's being fucking slow, forcing people to slice their code to crates as thinly as they can to try to speed the compilation up and minmax binary cache. I really want to believe that Rust compiler will get much faster in the future (and credit where credit due - Rust team is actively chasing ever-increasing complexity of the compiler, making it a bit faster every time), and this issue will go away naturally, and this is not some original sin brought on board by uncultured web programmers. Overall, despite me not actively programming in Rust anymore, I'm still overly positive about it, and want it to be as good as it can be, and hopefully it will.

I don't need Python because I have Jai

My goats please make this real

Never seen 3:08 and never will. Owe this one to Scruffy and his new reroutes <3

I think a lot of issues with OOP is in its historical context. Alan Kay coined term "OOP", but he actually meant Smalltalk. He never meant Java or C++. Unfortunately, Smalltalk died, its better relative (Objective-C) gotten pretty obscure, its other relative (Ruby) is, well, Ruby. So by late 90es people have two really mainstream monstrosities which are C++ and Java, with their own interpretation of OOP, using which leads to memetic AbstractSingletonFactoryBeans. I actually think clean code, solid, tdd, extreme programming and other things from around that time all were a good-faith attempts in "taming" the horrors of post-smalltalk high level programming wasteland. I don't think any of them are snake oil, or harmful, or any of bad in general. Anyway, this is my millennial understanding of some of the history lol, please be gentle!

On top of that you have quite questionable GPU drivers

Project of 10 files 1k lines of code each will always have better quality and readability than a project with 100 files where each one is 100 lines.

REAL. There are basically two types of Rust programmers

LLMs can't produce something like this yet. Even in a barely working state

Самый депрессивный период в моей карьере это когда я работал над проектом целый год, и в итоге все пошло в стол. И, конечно, постоянные митинги, линкединовый новояз, все как у автора.

pov you fatfingered 8 upon switching to insert mode. This single "feature" radicalizes me against vim so much lol

You used to need to pay huge money to optimization experts to review your code. In 2025, you can just post you code online and ragebait them to review it and give you tips for free. It's never been easier to write high-performance code than in 2025.

It's done! - 12gigs of packages downloaded - JDK broke during the update (it always does) - 9 packages vanished from AUR since last update - 3 dependency cycles detected (and resolved) by pacman - System is 6 years old (installed mid 2018) - Took ~ an hour - Bonus neofetch pic

People under this tweet (and in quotes) argue about what _true_ OOP is, further proving that this paradigm is a psyop and was never real in the first place. I've never seen FP/PLT people argue about a true meaning of Functional Programming, or C guys argue about what real procedural code looks like.

We are going for 3:06 peepoHappy

tech twitter programming language circlejerk lives in the biggest bubble, while the majority of software in the world is powered by C and PHP.

This is the perfect programmer vs mathematician question lol. Similar to "what's the opposite of 1"

Linux syscall ABI for system level programming. win32 through wine for desktop/graphics programming. There you have it, your perfect amalgamation of OS interface to have software that works forever...

@cmuratori's talk from @BetterSoftwareC will be absolute flames and hellfire when it drops public. Can't wait for it, and all the many twitter threads it'll cause. Especially what excuse brigade comes up with, considering how packed with receipts the talk is!

What's the point of using javascript over systems programming languages if it also has to go through the linker now???

Not going to lie, I'm like 95% sure this is just a shitpost to farm Lunduke. No way on earth somebody would seriously write it. It has to be a high-effort shitpost.

A big part of why I have a lot of respect for you is that you always seem to answer in a good faith even to obviously rude comments. Kids call it aura farming

Yes, the fact that they 100% knew and still did it only makes this W even more huge.

So it's not even me complaining about electron/react. Microsoft actually shown that you can ship electron app with serviceable performance and resource requirements like back in 2016 with first versions of vscode. Of course, in 2025 it's also a bloated sluggish mess, but back then you could not believe it uses electron under the hood.

Serializing and deserializing of your program data is trivial if you thought about memory allocations. If you just malloc everything all over the place, then you need a complex recursive code to assemble all of the data, count the size, then memcopy it into a separate buffer, and then have a code that reverses this process on the receiving end. But if you use custom allocators that tries its best to store your data hierarchies in a contiguous memory (YES, ARENAS), you can almost just take backing arena memory and straight up send it over the wire without any transformations.

Guys, guys! It doesn't cost "billions" to make a chat application UI, what are you talking about? They already pay huge salaries to the best of the best of the best candidates. Just make them write actually good software, how hard could it be?

This is an act of desperation. La Liga (Spanish football thingie) is extremely broke because nobody really cares about it apart from Real vs Barcelona, so they're really trying to squeeze every last bit of it.

4th one starts like a reddit posts - "Hi I'm 36(m, attractive)" :D

Now is unironically the best time to learn programming. You have no idea how much work programmers will have in a couple years!

"You just don't understand true deep meaning of Dependency Injection" ahahahahahh

Hot damn the @BetterSoftwareC talk on Xar isn't even out yet, but @LubaRaphael already dropping the implementation in the current Jai beta. Only 256 lines of code, including all comments and TWO different quick sort implementations for the array!

Linkedin is over there sir

Turns out, you can just do things!

I think "invert a binary tree" here is a catch-all phrase for CS-ey whiteboard interviews, not necessarily literally inverting a binary tree.

Man don't salt my wounds, it's so bad! I just yesterday tried out Arch without systemd. First time I tried a new distro in 6 years xd

Another day, another hash table replaced with a static array. Hitboxer used to have a table of key code -> its remapping, but there are only so many physical keys on all possible devices (actually, only 767 different key codes supported by Linux kernel). So 1000 statically allocated key sources should be enough for everyone!

Microsoft Windows crashout needs to be studied. Sometimes the only sane reason I can think of is that it must be an inside job to kill Windows lol

Even if this one gets reverted/fixed, there are MANY situations that followed the same pattern before. And it's certainly not the last one.

True, but you know what's even more funny? "Hoisting" is not even official term that is defined in ECMAScript. Hoisting literally doesn't exist. It's just a fancy term web bros invented because they are allergic to implementation details and would rather think in fantasy terminology than learning how it actually is. It's very sad because the way it actually works is so much easier to understand. As soon as you look at the difference between "cannot access before initialization" ReferenceError and "is not defined" ReferenceError and just slightly dig at environment records and lexical/variable environemnts - ACTUAL terms from the spec that might sound scary but actually way simpler - everything becomes so obvious. But yes, cargo-culting midvit tech recruiter will ask you about hoisting, and you will parrot, because you really need this 200k job, and being smartass on tech interviews is not what gets you jobs ^_^

Nah this is nothing compared to writing a comparable editor from scratch

musl does work better because you can straight up statically compile it in an easier way, so even if musl changes something - your existing apps will keep working. But distros that main musl (and apps that even support it) are far and few.
