Zig: A new direction for low-level programming? (bitshifters.cc)
Zig is a general-purpose systems programming language designed by Andrew Kelley. The language bills itself as “a general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software”.

Let’s code a TCP/IP stack, 1: Ethernet and ARP (2016) (saminiir.com)
Writing your own TCP/IP stack may seem like a daunting task. Indeed, TCP has accumulated many specifications over its lifetime of more than thirty years. The core specification, however, is seemingly compact1 - the important parts being TCP header parsing, the state machine, congestion control and retransmission timeout computation.

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.

Bit-permuting 16 u32s at once with AVX-512 (blogspot.com)
The basic trick to apply the same bit-permutation to each of the u32s is to view them as matrix of 16 rows by 32 columns, transpose it into a 32 u16s, permute those u16s in the same way that we wanted to permute the bits of the u32s [1], then transpose back to 16 u32s. Easy:

Learn Rust the Dangerous Way (cliffle.com)
LRtDW is a series of articles putting Rust features in context for low-level C programmers who maybe don’t have a formal CS background — the sort of people who work on firmware, game engines, OS kernels, and the like. Basically, people like me.
