My materials probably took 4-6 hours to write the first draft (I did most of it over two evenings, maybe one more just skimming the questions to figure out what things to talk abou…

There's no single "embassy" crate, but all the components (HALs, executor, usb, net, etc.) are all on crates io and have been for a long time.

It's worth noting that the support for ESP32 in Rust is official [0], and there are multiple full time engineers at Espressif working on developing and maintaining it. [0]: https:/…

It's really not so different! In embassy, DMA transfers and interrupts become things that you can .await on, the process is basically: * The software starts a transaction, or trigg…

Speaking as someone familiar with C and Rust (not so much Go!), although there's a parallel here to Rust's Traits, this actually is much closer to dyn Trait in Rust, which uses vta…

As others have mentioned, ~all of the embassy HALs support nearly 1:1 parity of blocking interfaces for drivers next to the async ones. You really can avoid async entirely while st…

If you haven't seen it, Mara Bos' "Rust Atomics and Locks"[0] is an excellent book on this topic, even if you aren't particularly interested in Rust. [0]: https://marabos.nl/atomic…

In safety industries, particularly aviation, "alarm fatigue" is a really big deal. You recognize that pilots have limited situational bandwidth, and you REALLY don't want to be bug…

Nordic's nRF family is the major other vendor I've seen doing this, almost all peripheral can be on any pin. It's definitely a big help for designing boards.

Kobzol is an absolutely wonderful person to work with. I also work in the Rust project, and any time I've interacted with him, he's been great.

You definitely can, I designed a 206x85cm standing banner for my last trade show as one of the first "production" things I built in Typst: https://typst.app/project/r1YNDcKpoF1sVXH…

Thank you for sharing, I'd never seen this before. It's an incredibly good read (and relevant for me) so far.

Thanks for Sublime Text! It's been my daily driver for over 15 years :). 10 of those developing Rust, and making heavy use of the Rust Analyzer/LSP plugin infra. I also want to tha…

For 3, if you haven't seen snapshot tests, like those using the insta crate, it makes it very easy to detect when values change like this in tests/ci.

This is entirely incorrect, Ferrocene manages a specification of a subset of the language here: https://public-docs.ferrocene.dev/main/specification/index.h... , including things l…

I bridged my bluesky account, if you're on mastodon and want to talk to me here, you're welcome to. Not sure if you need to opt-in on the mastodon side to be bridged to bluesky. @j…

You don't generally need to license Arm chips unless you are designing your own chips for sale, like STM32 or Raspberry Pi do. This is something very few companies do, relative to …

In general in Rust, lifetimes enforce that references to a thing do not outlive the thing itself. Even in unsafe code, it is possible to tie the lifetime of the allocations to the …

Tock-OS, Oxid-OS (the safety version of Tock-OS, like freertos/safertos), and Hubris (from Oxide Computers) are the main three RTOSs, Embassy and RTIC are common frameworks (but no…

Phil's writing on OS development is always a wonderful read.

Additionally, recursion and function pointers (including dynamic dispatch) are the other two "normal" language features that can defeat static stack analysis. There are techniques …
