@shonin @luckytran It's so ironic how eager those people are to listen to the government when it tells them to stop wearing masks.

I'm translating some C++ to Rust and the original C++ code silently relies on unsigned integer overflow just... somehow working for this math??? 🙃 This function has tests which I've also translated to Rust, and the only way I can get the tests to pass is by preventing overflow using wider integer types in the intermediate math... u16::overflowing_mul does not do the trick so I don't understand how the C++ code is working??? 🤔

Does overflowing a uint16_t on 32 bit MCUs just work by treating it as a size_t/uint32_t? This function works on 8 bit AVR microcontrollers, but those have their own assembler implementation rather than the C++... 🤷

Refuse the normalization of attacking hospitals. Don't let it fly under the radar, talk about it.

@skinnylatte @Viss In Chicago, only a small handful of bars around the city are allowed to be open until 4 AM and those permits are often opposed by neighbors and aldermen. I imagine it'd be quite difficult for a restaurant to legally be open at 4 AM here :/

Zionists watch Zone of Interest and treat it as a blueprint for what to do, but somehow manage to do it in an even more extreme way.

Bethlehem marks melancholic Christmas for second year in shadow of Gaza war

The excitement and cheer that typically descends on the Palestinian town in the occupied West Bank on Christmas are nowhere to be found.

@skinnylatte I think I'll try it with some fish that's been sitting in my freezer for a while.

@skinnylatte Tea-smoked food is a novel idea to me and I have to try it.

@Codeberg I went to the mentioned website in the spam and apparently a similar attack happened a few weeks ago on GitHub impersonating the same guy who had nothing to do with the spam. 🤨 https://www.bleepingcomputer.com/news/security/github-projects-targeted-with-malicious-commits-to-frame-researcher/

I've only used WebAuthn with Yubikeys and Bitwarden on Firefox on Linux, so I had no idea how badly Big Tech fucked it up on their OSes and browsers. 😞

@dcbaok @cwebber Get more than a few, and give them away! N95s are so cheap, you can get them for less than a dollar each! Here's a pack of 50 comfortable N95s for just $35 https://www.zoro.com/3m-n95-disposable-respirator-universal-white-pk50-9105/i/G0862784/

@jalcine It's cloudy and raining :/

It's wild that the full Rust standard library can run on ESP32 by wrapping the C library from Espressif's C SDK. You could write an HTTP server with Tokio on a cheap little microcontroller!

Also apparently embedded Swift is a thing now and at least someone at Espressif cares about supporting it.

AFAICT Espressif and Infineon are the only MCU vendors officially supporting Rust. But Infineon's support seems very early and understaffed; their HAL crates haven't had any updates in over a year (https://github.com/Infineon/traveo-t2g-pal/commits/develop/pal_crates/cyt2b6_d) and only has 3 contributors.
