Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Memory leak proof every C program
Hilarious!
But I remember the first time I saw such a program which never freed anything: jitterbug, the simple bug tracker which ran as a CGI script.
It indeed allows a very simple style!
Meanwhile, use ccan/tal (https://github.com/rustyrussell/ccan/blob/master/ccan/tal/_i...) and be happy :)

My review of the C standard library in practice
Please note that the above link has been claimed by squatters and isn’t the right link for CCAN anymore! The maintainer suggests [1] just using the GitHub repo [2] instead.

[ROAST MY CODE] Implementing generic vector in C
This is a great learning exercise but not very useful because using void* creates practical problems that the compiler cant help you with. IMHO, for a nice vector in C look at https://github.com/rustyrussell/ccan/blob/master/ccan/darray/darray.h

Toward a better list iterator for the Linux kernel
For more advanced intrusive lists in C, I've found that ccan's tlist2 (https://github.com/rustyrussell/ccan/blob/master/ccan/tlist2...) provides a decent model here.
Compared to the linux kernel's intrusive lists, it also tracks the offset of the list_node within the structure contained by the list, which eliminates another class of problems. It does still have the "using the iterator after the for loop is over" issue discussed in this article, but it also already tracks the types as Linus proposed doing in the article to resolve the issue.

Good C Source Code
ccan library https://github.com/rustyrussell/ccan I think it is used also in the linux kernel(?)

What are your favorite C resources? They can be either for learning or reference.
ccan (analagous to cpan, but for C rather than Perl.)

Dynamic link list
You could use a discriminated union in your list node. You could use a void pointer in your list node, allocate space as needed and memcpy the date into this space, or don't allocate and store pointers to the original data. You could use an intrusive list, like this.

The Byte Order Fiasco
The fallacy in the article is that anyone should code these functions. There's plenty of public domain libraries that do this correctly.

SectorC: A C Compiler in 512 bytes
Not using this, but tangentially related is (full disclosure, i am a maintainer of this project) live-bootstrap, which uses about a KB of binary to do a full "Linux from scratch" style thing - read https://github.com/fosslinux/live-bootstrap/blob/master/part... for all 143 steps you have to go through to get there.

what is the smallest linux system capable of building itself?
live-bootstrap builds a variety of intermediate systems, starting from a <1KB binary seed (kernel excluded). Check parts.rst for a description, it's kinda wild just how many C and C subset compilers get compiled... but the end result is a system with musl and GCC 4.7, from which building the latest GCC is 2 steps away.

Ken Thompson: Reflections on Trusting Trust (Turing Award Lecture)
There is also live-bootstrap which uses a similar bootstrap chain to Guix (stage0 -> Mes -> tcc -> gcc), but without needing Guile/guix-daemon binaries etc. The whole thing starts with just a 357-byte binary seed (source)!

GHC blog: Migrating from Make to Hadrian (for packagers)
There's some cool stuff being done in this area. For example, live-bootstrap goes from a tiny, auditable binary seed to a full GNU userland using only source code (and a Linux kernel).
