After adding support for constrained-memory environments to the Deku parser, we've had some interest in using Deku for #rustlang binary parsing.
So, Andrew has put together a great Deku walkthrough doc, parsing the ELF format as an example.

Code Constructionist @arjeffery.bsky.social has recently had contributions to #rust crate Deku merged, which allow implementing safe, reliable, binary-protocol parsing within #embedded microcontroller environments.

Your periodic reminder about the Bluesky network analyzer, a surprisingly useful tool for finding people you know who you probably intended to be following if you knew they were here. It's eerily good, especially if you use "favour niche accounts" mode.

Bluesky Network Analyzer
Find accounts that you don't follow (yet) but are followed by lots of accounts that you do follow.

These did seem to be very good years, at least in comparison to recent times. Also happened to coincide with me joining ozlabs, which turned out to be pretty good for my career too 😄
Twitter roughly 2015-2019 was SO GOOD for my career
I learned so much from following people who are a lot smarter than me, and understanding how they think
I only started tweeting myself in 2020 or so, and then the whole site got borked more recently, and I kinda wish I could go back

An orange site article involving assembly analysis for performance reminded me of the time I got a 2495x improvement out of tceetree when run against Linux v4.12 medium.com/@andrewrjeff...
Optimising tceetree for the Linux kernel
Recently I set about learning the Linux kernel’s pmbus subsystem, and started hand-drawing a call-graph to show myself around. Needless to…

Well, openbmc/libpldm can finally be built with `-DNDEBUG` and I've set `b_ndebug=if-release` as the default in meson.build. It only took ~100 patches and three tags 🥴

Guess I should do an intro post: Hi I'm Andrew, I'm an open source software nerd who looks after implementations of some DMTF PMCI specifications and enjoys rage-debugging awful firmware issues. At some point I intend to enjoy playing guitars again.
