#jj-vcs part 1: what is it

andre.arko.net/2025/09/28/j...

If you do #embedded #Rust on the #rp2040 with elf2uf2-rs, and you struggle with the recent "Unrecognized ABI" error due to a change in Rust's elf header for `thumbv6m-none-eabi`, I've landed StripedMonkey's patch in both Arch Linux and Homebrew, so if you use those packages, things should work […]

I'm probably going to post this a couple times, but if you are a Rust dev, who cares about messaging between tasks/threads/process/devices, and would be willing to do me a personal solid, I want YOU to help me put Ergot through its paces:

Sans-io: meh YouTube video by Self-Directed Research

This week, I attempt ill-advised-slide-writing-time-travel, and @fasterthanli.me and I chat a bit about "Sans IO" protocols on @sdr-podcast.com!

(bonus, keep an ear out from the best punchline from @amandamajor.bsky.social :D)

Fun data structure of the day!

A joyful Ferris the crab throws confetti under text that reads "Happy 10th birthday, Rust 1.0!"

Today marks a decade since the 1st stable release of #rustlang 🎉 To commemorate this milestone, we asked Karen Tölva (Ferris creator 🦀) to design a celebratory graphic & answer a few questions in our blog.

Congrats to EVERYONE who has made Rust what it is today 🧡

2. I wanna try postcard in this case.
a minor note: I need to ensure other implementations (like in Go, JS) can easily decode it.

Currently Im considering the Native Redis Values vs. JSON for message serialization.
Personally, I don’t like JSON due to its overhead. I have 2 choices:
1. im using serde_redis to convert the object we want to send into native Redis data ( Redis::Value::Array(...) ).

@jamesmunns.com
i have a BE service at work, which gonna use a rust lib that provides a high-level abstraction over Redis Streams. Basically It implements a message bus pattern using Redis Streams as the underlying transport mechanism.

Apply Profile-guided optimization to improve performance · Issue #9412 · rust-lang/rust-analyzer Profile-guided optimization (PGO) shows great promise in improving the speed of software, last year tests where made on applying it on Rust itself improving build time by ~15%. Would it be feasible...

today's Rust Analyzer release ships with profile-guided optimizations, making it roughly 20% faster. Time to upgrade! github.com/rust-lang/ru...

been away from the keyboard for almost 3 weeks to renovate my house, i miss my unfinished projects so much, hopefully the renovation will be finished by the end of this month so i can restart my unfinished projects 😮‍💨

Having just told the story of how I made a POC for #sdfstudio, a data pipeline visualizer, and signed a contract to continue work on the project, it seems to be a good time to tell the full story of how a I got a job through #opensource

It's not a Presto, it's a really big PicoSystem!

Good things come to those who wait (for 8 years!)

I also found out an interesting benchmark repo recently

In one screen:
1. data integration/dbt code
2. analysis of SQL queries
3. db connections/browser
4. result of queries
5. docker build
6. dbt run
7. postgres
8. more windows/sessions (tmux)

More dotfiles.ssp.sh.

Yes, I have some ideas but not very soon because I'm still learning PCB design lolol...
for now I'm just tinkering with assembling some hardware components.

saw another post on your eurorack for Poststation demo, could you share the design files? or some docs would be greatly appreciated too! 🤓

crates.io: Rust Package Registry

Today I published arm-targets, a Rust crate that looks at your target string and lets you mark code as only working on specific versions of the Arm architecture. Ideally Rust would have built in target features for this, but it doesn’t.

Both are okay, I always enjoy your blog posts on embedded field no matter what PL it is 😁

This is so damn cool! Wish I can touch it directly and watch demo in real life 😙
