Not sure if it exists, but I'm looking for an FPGA with on-chip MCU with support in an open-source toolchain. Mostly for trying FPGA programming again. Ideally something like an ICE40 with a RISC-V micro in one chip.
At my old job I really enjoyed working with the Altera SoCs, having custom peripherals in the FPGA, but still being able to write normal software to process the data was really nice.

But if I don't want to open Quartus or Vivado again...

Bevy Jam #8 is up on itch.io (https://itch.io/jam/bevy-jam-8) and ready for theme submissions in ⁠jam-theme-voting on Discord.

If you're looking to participate, note that our rules have changed for this one: all AI use is banned for this jam (go learn stuff! have fun scrambling!) 💚
Jam dates are October 31st to November 8th 🎃

Anybody need a reference?

Someone should invent a (fast) computer that doesn't care about memory alignment.

The streets would fill with cheering crowds and the dancing would continue to dusk.

For his internship, Camiel dove into using TrustZone-M with Rust. In this blog, he describes how TrustZone-M currently helps you secure your embedded device and shares a minimal working example for the Raspberry Pi Pico 2:

Mmmmhh, apple sauce is amazing for a sore throat. Too bad it's so bad for everything else

Btw, I won't be maintaining two disk versions *for free*. The equation changes if the extra work is paid for.

So ehh, hit me up if that sounds attractive. There could even be slow transition where old pages are read using the old format and new pages are written in the new format

Half a page state is at worst just one byte. 2 bits minimum are used for the state, so there's 6 bits left. Double up every bit and you have 3 bits or 8 versions.

So maybe just a parity bit? Then there's 5 bits for 32 versions. At this rate s-s could then support 80 years of development

I could add a little disk format version field in the page state I think. That could be nice to have. Not sure.
At least there could be a (runtime) error for version mismatch. But that has to be bitflip resistant too, just like the rest of the code.

I've got 2 bugs and 2 enhancements for sequential-storage that require a "disk-breaking" change. So at some point I'll come with a properly breaking release.

I don't think I want to maintain two disk formats.

So if you have an idea for a (disk) breaking change, please open an issue!

3 days later, yep definitely a bad situation 🤒

Minesweeper for 2026?

Brilliant.

Oh, speaking of discord. #duckduckfedi We currently have ours bridged to matrix with https://t2bot.io/. Functionality wise, it works really well, surprisingly seamlessly, but the bridge has been really slow lately (several minutes for messages to pass across)

Is there a better alternative out there somewhere? Or should I just try to self host this one and assume it is server issues causing the slowness

Since the start of this month I've been with @tweedegolf for 5 years!

ah damn, RIP Margaret Hamilton.

she took safety-critical software engineering seriously, and got people to the moon and back.

I've got the beginnings of a sore throat but I've also got "goto definition" working in the LSP, so it's unclear whether this is a good situation or not

Rust 1.99.0 has been released, and this time both @folkertdev and Björn have 100+ contributions to their name, and Folkert co-hosted the Changelog video!

Opt-in is the opposite where reasonable users must always provide a list. The advantage is that they will do so because they must.

So... I don't like either of these options.

Opt-out has the disadvantage that people aren't going to opt-out on their own for nothing. So adding new traits will still break people in practice. The advantage is that a default user just gets everything which is likely what you want.
