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

Tool Assisted Speedruns are 100x compared to manual speedrunning. If you still practice and speedrun yourself you're literally ngmi. TAS will fully replace traditional speedrunners within 6 to 8 months from now, just get over it.

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

Celeste is the tightest and the most satisfying momentum-based platformer in the world. And the meat of it is open source for you to learn! Absolute must for study if you're making a platformer game! It being a single 5k lines of code class instead of a mess of abstractions and indirection makes it very straightforward to follow

I caught TDD virus at the start of my career, and this talk by Erik Meijer saved me! As often the case with snake oil salesmen, they take a good core idea (write usage code first), and turn it into a parody to sell books and courses to people who don't know better. This talk is 10 years old, but still relevant today. LLMs like writing A LOT of tests, but you must delete most of them and only leave integrational and e2e ones that test real system behavior.

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".

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.

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!

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"

I hate exceptions. Here's why, and also some crazy ways how the most used library in the world abuses them just to draw loading spinners.
