A diagram of C23 basic types (wordpress.com)
This week on the C committee mailing list we had a discussion about how C’s types are organized into different categories. At the end I came up with a diagram with that organization. It basically translates the section “6.2.5 Types” of the C23 standard into a graph of inclusions.

Writing Programs with Ncurses (invisible-island.net)
This document is an introduction to programming with curses. It is not an exhaustive reference for the curses Application Programming Interface (API); that role is filled by the curses manual pages. Rather, it is intended to help C programmers ease into using the package.

Strncpy? just say no (2011) (liw.fi)
This is a rant. I’ve made it in various forms in various places over the years, and I think it’s time to put it somewhere so I can point people at it, and stop repeating myself.

Writing a Simple Garbage Collector in C (maplant.com)
People seem to think that writing a garbage collector is really hard, a deep magic understood by a few great sages and Hans Boehm (et al). Well it’s not. In fact, it’s rather straight forward. I claim that the hardest part in writing a GC is writing the memory allocator, which is as hard to write as it is to look up the malloc example in K&R.

Reinforcement Learning in less than 400 lines of C (github.com/antirez)
This code implements a neural network that learns to play tic-tac-toe using reinforcement learning, just playing against a random adversary, in under 400 lines of C code, without any external library used.

Robust Wavefront OBJ model parsing in C (nullprogram.com)
Wavefront OBJ is a line-oriented, text format for 3D geometry. It’s widely supported by modeling software, easy to parse, and trivial to emit, much like Netpbm for 2D image data. Poke around hobby 3D graphics projects and you’re likely to find a bespoke OBJ parser. While typically only loading their own model data, so robustness doesn’t much matter, they usually have hard limitations and don’t stand up to fuzz testing.

Examples of quick hash tables and dynamic arrays in C (nullprogram.com)
This article durably captures my reddit comment showing techniques for std::unordered_map and std::vector equivalents in C programs. The core, important features of these data structures require only a dozen or so lines of code apiece. They compile quickly, and tend to run faster in debug builds than release builds of their C++ equivalents. What they lack in genericity they compensate in simplicity. Nothing here will be new. Everything has been covered in greater detail previously, which I will reference when appropriate.

Fixing C Strings (thasso.xyz)
It’s well-known that null-terminated C strings are bug-prone and unsafe to use. They’re the stereotypical footgun. I’ve been tinkering in a bare-metal environment recently, writing all code myself, including the common types and routines you find in libc or similar. In all the code I wrote, there is not at single null-terminated string, and I have yet to encounter a bug related to bounds checking on strings or buffers.

In C some things aren't what they seem – The Craft of Coding (wordpress.com)
In C it is possible to make up things that don’t exist. For example this can lead to operators being created when they don’t exist, at least in the eyes of the programmer. Take the “–>” operator. This operator doesn’t exist, but can function as if it does. Here is an example program:

C99 doesn't need function bodies: VLAs are Turing complete (lemon.rip)
The 1999 revision to the C programming language brought several interesting changes and additions to the standard. Among those are variable length arrays, or VLAs for short, which allow array types to have lengths that are determined at runtime.
