Starting tomorrow, you will be able (on linux without cross-compilation) to install and use the Rust GCC backend directly from rustup! To do so:

Add GCC and the GCC codegen backend to build-manifest and rustup by Kobzol · Pull Request #151156 · rust-lang/rust
This PR adds the GCC codegen backend, and the GCC (libgccjit) component upon which it depends, to build-manifest, and thus also to (nightly) Rustup. I added both components in a single PR, because ...

Really scratching my head why WireGuard explicitly disables IPv6 link-local addressing. Sure there's no MAC address for EUI-64, but you could easily derive one from the interface public key or allocate a random one like many operating systems now do.

Wanted to try out WebGPU, so wrote a little shader to replicate how I remember the SNES to look on a CRT when using composite input.
I'm sure it's horrifically inefficient, but the chroma sub-sampling look feels pretty close.

One of the most frustrating artifacts of tools like Copilot and Chat GPT is partial/limited context. It doesn't need much to sound competent and that it "understands the problem", but scratch beneath the surface and you find there's nothing really there.

Just for fun I decided to try doing some of #adventofcode on the Flipper Zero using flipperzero-rs. My initial try at Day 1 OOM'd because of Vec's amortized re-allocation strategy, but I can work around that by giving an explicit capacity.
Exposed a few of the rough edges in flipperzero-rs API too.

We keep hearing that "it's getting too expensive to make games/software/movies/tv-shows/albums/etc." when doing so has never been easier or more accessible.
