DNS records in zone files add up to gigabytes. The simdzone C library can parse them at gigabytes per second. It is part of the popular NSD and likely in a server near you. Details at… Parsing Millions of DNS Records per Second, Software: Practice and Experience 55 (4), 2025…

ARM64 kernel now supports echoing user input. 372 bytes! It was fun getting backspace working on a UART! Code: gist.github.com/rrampage/c666e… #qemu #arm64 #osdev

Is there any cheap (<$100) ARM64 board/device/smartphone which supports nested virtualization? The RaspberryPi 4/5 don't seem to support it. #virtualization #arm64

Wrote an ARM64 implementation of `kill -9`. Compiles to a 208 byte ELF! The fun part was writing an `atoi` implementation for unsigned ints and reading `pid` from `argv[1]` cc @abhi9u Code: gist.github.com/rrampage/7f700…

Hand-crafted ELF using ARM64 assembly (no linker!): gist.github.com/rrampage/74586… Wrote the ELF headers in the assembly file. Uses `as` to create the object file and `objcopy` to fish out the ELF. Overhead of ELF and program headers is 120 bytes. Actual code is 12 bytes. #linux #arm64

i want to write some advice for handling intermittent bugs! So far I have: * add extra logging that triggers when the bug happens * look for time patterns (is it right on the hour?) * read the code really carefully to figure out how the Weird Thing might happen

If you're wondering what "P-four-nines" means, it's the latency at the 99.99th percentile, meaning only one in 10,000 requests has a worse latency. Why do we measure latency in percentiles? A thread about how how it came to be at Amazon...
