Every year I promise to post more of what I'm doing, which unfortunately doesn't make it happen.
Interested in programming languages / algorithms / software tooling, but I spend most of my time with embedded(C, C++, Rust).

It’s always a good idea before you say anything publicly about someone’s intentions or ideas to figure out if you are comfortable with the same being done to yourself

in-band signaling is always a mistake and unix tooling is full of in-band signaling https://mas.to/@zekjur/116022397626943871

Attached: 4 images PSA: Did you know that it’s **unsafe** to put code diffs into your commit messages? Like https://github.com/i3/i3/pull/6564 for example Such diffs will be applied by patch(1) (also git-am(1)) as part of the code change! This is how a sleep(1) made it into i3 4.25-2 in Debian unstable.

I'm having fun finding out how much less code Rust's integer functions generate for rp2350's RISCV cores (when all of it's bitmanip extensions are enabled):

Finally getting around to listening to the Wookash Podcast where defer is, apparently, mentioned. I guess I should listen to this thing in ful-- oh my god it's two hours?? Well, time for the 2x speed buff.

Alright, with a last minute async Rust bug fixed (thanks 2024 edition), it's time for the first #bevymergetrain of Bevy 0.18! The release branch has been cut, and we're merging feature work again!
Let's go over the 10 open community-reviewed PRs in our backlog for this week <3

It’s a good thing we’re keeping our dependency count low, I think to myself, as I read about how my UI framework also provides threads, networking utilities, data structures, floating point math, D-Bus, cryptographic utilities, geographic utilities, and a Bluetooth implementation

I wonder if early-in-career folks would appreciate folks like me doing little AMAs on here.

Cursed knowledge learned today:
thumbv8 targets (like the RP2350!) start with their memory marked as "non-sharable" at boot, meaning that atomics between the processors *don't actually work*, until you either set the regions sharable in the MPU, or set a global "everythings sharable" flag.
