File explorer is something that a single dude from Croatia can write in a couple years on and off, and it will be better than anything a multi-billion dollar corporation has ever done in decades in this department

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

I've been using Linux for 15 years, and I hate terminals. Here's shell workflow that I've been using for the past 8 years.

SQLite is a masterclass in a library design. It shows how projects of even huge complexity can be very simple and unobtrusive to use. You can learn a lot from them if you are library author, regardless of programming language.

Teaching Microsoft employees how to implement a portable sleep: - C - absolutely from scratch - not even libc - the only dependency is The Kernel - some inline assembly magic included

You do not need Windows to create Windows executables. I fee like this will become very important few years into the future, when Microsoft finishes "the job".

If you properly vendor your dependencies, you don't need a complicated build system like cmake, or nix. All you need is a simple build script, 90% of which will be setting your compiler flags. If you don't believe this - RAD Debugger is over 200k lines of code, and clean debug build takes just a few seconds, and it has two dead-simple build scripts - one for Linux, and one for Windows. That even a person who never seen a shell script in their life can instantly understand. Linux packagers hate when you say this, because "boo hoo what if freetype that you vendor has security bugs???", but real reason they hate this is because it strips their perceived importance of infinite Sisyphean ecosystem churn to make sure exponential explosion of packages on your system has illusion of working together. I guess eventually even Linux people realized that they can't take it anymore, and invented flatpaks. For me personally, I pretty much landed at a middle ground of "dependencies are good, but automated distributed dependency management is bad"

The worst thing about dealing with C (and C++ to an extent) code is understanding and debugging macros that you didn't write. Here are a couple ways of how to deal with them!

Your agency is all you have left. Stop using LLMs for writing and reading, it actively hurts you.

You should stop using environment variables. They are a horrible untyped and unsafe mutable global state. A ticking time bomb. Even Rust can't save you.

Graphics programming tutorials always skip over "the platform" part, even though I think it's very important to struggle through it at least a couple times. So let's see how to set opengl up from the absolute scratch on Windows and X11 (bonus part - how X macros work in C)

Did you know that NaN exists not only to troll JavaScript programmers - but it is actually used for NaN Boxing, which is a very cool optimization technique!

Let's look at assembly around execution stack and variable initialization in C, talk about why you always need to initialize variables, and about best practices on what to initialize them to.

Let's compare tagged unions in Rust and in C, and then steal some of that type safety from Rust with a bit of a compiler and macro magic so that C can have nice things too!
