Basic

• Bill Sky - The Computer Guy (Playlist) .

  • Haven't seen it yet, but I think I like the guy.

• Nice explanation with Teej .

  • Starts with the basics, like int main() { return 0; } .

Tips

• Tips for C .

  • C Versions.

    • He uses C99.

  • Compiler Flags.

  • Unity Build.

  • Debugger.

    • Recurring segfault problems can only really be debugged with a debugger. It's very hard to debug a segfault with prints, and the segfault error given is usually terrible and not descriptive.

  • ASan.

    • Address Sanitizer.

    • Accessing memory out of scope causes a Segfault, but accessing memory within the scope of something else in the code can cause memory corruption.

    • For this reason, ASan is used to check if access is within the array bounds, etc.

  • Arrays and Strings.

    • He creates his own arrays and strings using structs, so he can implement his own "boundary checks", etc.

  • Indexes and Pointers.

    • Suggestion: store the index of an object instead of a pointer to the object.

    • Apparently, this helps with array resizing, etc.

  • Arenas.

    • Related to Lifetime.

    • "Arena = One Lifetime".

    • It's where you store all data that has the same lifetime.

Includes

• Unity Build.

  • A way to handle #includes  and avoid duplicate includes.

  • I found it interesting; I saw it being used in Zig too.

• #pragma once  in .h  files.

Libraries

• gb library .

  • A helper library by Ginger Bill, to group everything together.

  • (2025-07-03) On a quick glance, I found it very useful, as it resembles Odin types.

• stb .

  • Single-file public domain libraries for C/C++.

  • Created by Sean Barrett.

  • ~ Advice for Writing Small Programs in C .

    • Quotes :

      • The C std library is terrible.

        • Some APIs are not designed very well.

        • strcopy  is notoriously bad.

      • I needed a way to systematically reuse code.

      • JAI is quite interesting.

      • He worked on Thief , creating the render engine.

        • Thief is known for having good programming; use of 'fat structs'.

        • It was the first time ECS was used; the entity is just an ID for a lookup table.

      • OOP is a waste of time.

      • Spend your time writing useful code, not doing other things. Aka, minimize overhead.

      • Many libraries are written only for big projects.

      • He disagrees with Casey on some things, but agrees quite a bit on others.

    • Overall, the video is mostly irrelevant; the only "relevant" things are the quotes I put.
