Turns out some stupid distros were shipping screen with suid bit 🤦♂️ https://security.opensuse.org/2025/05/12/screen-security-issues.html anyway, take care and update your screens

TIL Linux is not setting the POSIX TMPDIR environment variable anymore and it's just relying on the XDG_RUNTIME_DIR one. Kind of make sense to have and use a per-user tmpdir. It's not even safe to assume /tmp is a valid place because linux-based systems like android also have their random way to define this. #unixfun

@amszmidt @korreckj328 imho defining some sane restrictions on symbols is somehow cleaner. It’s like having emojis or spaces in filenames. Surely we can even make files with slashes but it feels wrong

Now #Swift permits functions with spaces in the name. TIL that Kotlin, Zig, Scala and other languages already supported this “feature”.., https://github.com/swiftlang/swift-evolution/blob/main/proposals/0451-escaped-identifiers.md

Fyi, the deprecated decorator has been deprecated

@delta im curious if there are stats about the amount of active users too

@dexternemrod @delta thats what i though, despite how nice would be to have such thing for statistical purposes I guess it’s fine to focus on amount of registered relays :) cool indeed

console.lol()

Seriously speaking, it’s 2025 and we are all still depending on monolitic kernels written in unsafe languages and hardware support is still exposing the same problem we had 30 years ago.

@argv_minus_one @wolf480pl @hunger imho the weak points or rust are:

- complex language
- moving and evolving target
- only one compiler exists
- heavy cpu and memory requirements
- added tech debt as custom wraps need to be handcrafted all the time

Gccrs is unfinished but i want to assume it solves some of these problems, what about the others? im trying to be constructive and not get into a flame. Im not a rust or a kernel dev, despite i wrote drivers, kernel patches and wrote some rust too, so im probably not seeing the whole picture.

PD: I would love this thread can become into a constructive discussion.

Rust was never designed to replace or interface with C. Despite its safety benefits, i think it was too early and probably a bad idea to make it into the Kernel. Despite the ego flames, all the dev conflicts prove that. But I guess that monster (the kernel) is too big to fall. #rust #kernel

Damn, there's no #ghostty for Debian/Ubuntu https://ghostty.org/docs/install/binary

One more device to run @radareorg #phosh #pmos

I never understood if nano users are real or just a meme

The hardest part for me when doing slides is to simplify all the concepts into something humans can process and then I feel like i’m missing like 90% of all the stuff I want to share. Can’t find a balance

Today I was planning to integrate r2ai with Cozmo. But got migraine and I guess the total world domination can wait a day.

Sadly the company behind this beautiful robot go bankrupt in 2019 and they didnt released the source of the firmware. But i bet i can reuse the old sdk or reverse engineer the app with r2frida to get the job done.

PD: if you do software and your company go bankrupt, you should morally be forced to opensource everything.

Can I trust this window? Oh yeah I do

To all Americans from Europe: welcome back to the right time 👋
