As part of the #IETF hackathon, the people of Ariel OS are currently working on using #WASM to provision new functionality securely onto embedded systems.

so glad I can be learning Rust from the experts at Adobe, their beautiful elegant code is really an inspiration 😊

$impl<'a> From<&'a dyn Stream> for StreamAdapter<'a> { #[allow(invalid_reference_casting)] fn from(stream: &'a dyn Stream) -> Self { let stream = &*stream as *const dyn Stream as *mut dyn Stream; let stream = unsafe { &mut *stream }; Self { stream } } }$

Hmmm, not sure!
Maybe check this toggle?

How though? I think my counter is on 7000+ days.
Do you never shut your PC down?

An update has to be pending really long before windows auto-reboots

Ok, so there are two coalitions possible I think.

Center: D66 VVD GL-PVDA CDA
Center right: D66 VVD CDA JA21

I hope for the former.

I had hoped we could do without the VVD for once, but alas.

Ha lol, yeah there's lots of cursed stuff around!

On cortex-m, if you have a function at address 0x1000, your function pointer must be 0x1001 or your chip will crash (sometimes) :P

Folkert has become a co-maintainer of rust-lang/stdarch, which defines vendor-specific APIs that are used by the Rust standard library and Rust users writing explicit SIMD code.

In this blog, Folkert explains how they try to reduce the maintenance burden: buff.ly/X0F6yei

New #rust blog post on how we could get types that cannot be forgotten, types that must be moved, async and const drop, and other fun stuff:

Copy types cannot impl drop. So T: Drop is !Copy.
Not exactly what you're asking, but maybe close enough?

Alloc in consts is coming!

`Vec::push` in consts MVP by fee1-dead · Pull Request #147893 · rust-lang/rust

Neutral: AI features on by default. First time I've ever worked with AI suggestions. They're terrible and a net negative in productivity. But it's customizable and with one button click all AI features can be disabled.

Dion Dokter @diondokter.nl · 17d

Plus: Rust support is good and the available extensions are plenty enough and good enough.

Minus: Very little color by default. A lot of gray with relatively low contrast text. Same for icons. Can be fixed with themes though.

Plus: Everything worked well from the start. No weird problems.

Minus: The git gui doesn't have tools to interact with branches (creating, merging, etc). This is something I really miss.

Since Zed is out for Windows, I thought to give it a spin!

Authored this PR with it: github.com/diondokter/d...

TLDR, it's ok.

If I had 3 wishes from a genie, the first one would be:

Make every hardware designer stop using 2.54 mm pin headers for debug ports.

Give me a Tag-Connect, 10-pin FTSH-105 or anything civilized!

Nice big refactor done on device-driver.

The 'device' is no longer the only thing the compiler knows about. It's deeper integrated, which unlocks the ability to have multiple devices in one manifest.

On its own not too exciting, but the plan is to add templates so device families can be supported.
