From a net-effect standpoint, Rust's implementation of async/await is fairly similar to protothreads, which were used even on smaller AVR and MSP430 targets where rtos threads weren't practical. That being said, protothreads

For what it's worth: references in Rust (both `&` and `&mut`) are just pointers with stronger static (compile time only) analysis. They have zero runtime impact vs raw pointers. Even heap allocations like `Box` are still jus

Aw, it's a shame this is an older post, I was wondering if there was a published attack for the relatively newer nRF52. The nRF52 is already a little long in the tooth (there's an nRF53 available, and nRF54 now/soon), but the

This is something I'm also working on, but using off the shelf hardware for now and working on the OS first[0]. I'm going for something lower spec and portable for now, mostly because there are a fair number of relatively well d

MSVC is the default compiler backend for Rust on windows. You can also switch to use GCC tho: https://rust-lang.github.io/rustup/installation/windows.html

This is interesting, but many permissive licenses still require attribution at the project or file level. If Codeium doesn't produce these when producing "verbatim enough" snippets, how is this actually better, besides avoidi

For what it's worth, the entire esp32 family is officially supported in Rust by espressif themselves [1], and the stm32 family is probably one of the most widely used cortex-m families in embedded Rust as well[2]. [1]: https:/&#x

KiCad is a really excellent tool, usable for a pretty wide set of use cases, even professionally if you don't need a specific tool like antenna design or complex high speed trace matching. All of the low and high code board houses will

Another confirmation of this. I ordered a Librem 5 at the end of 2019, and have not gotten any meaningful update on it. I (now) know someone who ordered earlier than that, who has been trying for years to get a refund for his device.

Yep, we have `fence` for runtime+compile time barriers, and `compiler_fence` for compile time barriers. They take the same Ordering enum as atomics.

The generic name for these panels are "HUB75", based on the interface they use for driving them. I can confirm, these are $10-15/ea in small quantities on sites like Aliexpress. But you're likely right, they were probabl

This was a beautiful story, but was it fiction? I can't find the song named in the article, nor the "King Ozy" producer they are talking about. Edit, the author, Robin Sloan, is a fiction writer. That's... a little disap

Congrats on the release! Were there any organizational or policy changes after the "9 month grind" [0] tweet? Or is this still the policy of the bun/oven org? [0]: https://news.ycombinator.com/item?id=32584211

For those curious, I went and looked it up, and the one way (not round trip!) light travel time to the moon is about 1.3 seconds, and one way light travel time to mars is 3-22 minutes or so, depending on how far they are at the time. So maa

fwiw: cortex-m parts would be pretty conclusively referred to as 32-bit parts (due to the 32-bit address space/pointers as well as 32-bits being the native word size of the platform). Other 32 and 64 bit platforms support some kind of

stm32g0 parts (for example the stm32g030) can often be in the <$1 range, or <$0.50 at decent quantities. I think there is even an stm32c0 line planned at a lower price point. There are likely lower cost parts, but the REALLY cheap 32

Author of postcard here, I don't remember exactly where I got my bit twiddling example from, lemme see if I have notes from that. postcard's zigzag encoding matches phoboslab's psuedocode. Edit, not totally sure, but this wik

I learned git on tortoise git. It's definitely a good and simple option if you're on windows.

Both Rust (via 'cargo fix') and Clang (via `clang-tidy -fix` have ways of doing this, I don't think I've seen someone offer this automatically/interactively though. I don't think I've ever used them, but I

What would you like to know? I'm sort of writing as I go here, from scratch. You have to start somewhere. The problem is "good vs bad" is a little domain specific. I can show something that works for embedded, but it won&#x27

Hi, I am James, and I do in fact get paid. That being said: I do this as a consultant, and my official job title has never been "system engineer" (usually some flavor of software engineer).

Hey, author here :) Requirements changing are a reality. In safety critical fields, these changes are noticed by using traceability tools. I haven't written this far yet: but you should have a process for changing things like system re

Yeah, my third party messenger tool (beeper) threw that same error. I'm guessing something went wrong in a deploy. Hopefully they'll roll it back soon. I can still view pages when logged out, but trying to log in on an incognito w
