systemd lost the plot a long time ago. they stopped following the Unix philosophy and now they're busy adding nonsense like age verification. Just like Firefox, systemd doesn't understand its core user base. There are plenty of distros without systemd

@janmon It's the reason why I went tubeless. I just refill the sealant twice a year and have a CO2 canister with me at all times. Got my tires self-sealed at least twice in 3 years.

Removing physical buttons from hardware was one of the worst product design decisions in history and everyone involved should be publicly shamed.

Today in InfoSec Job Security News:

I was looking into an obvious ../.. vulnerability introduced into a major web framework today, and it was committed by username Claude on GitHub. Vibe coded, basically.

So I started looking through Claude commits on GitHub, there’s over 2m of them and it’s about 5% of all open source code this month.

https://github.com/search?q=author%3Aclaude&type=commits&s=author-date&o=desc

As I looked through the code I saw the same class of vulns being introduced over, and over, again - several a minute.

Build software better, together

GitHub is where people build software. More than 150 million people use GitHub to discover, fork, and contribute to over 420 million projects.

I was very disappointed to hear that it got cancelled.
We need more shows/movies based on Gibson's work. It's more relevant than ever.

Ever since the Matrix was released in 1999, cell phones have been steadily replacing landlines - which were shown to be the only way to escape.

An (almost) catastrophic OpenZFS bug and the humans that made it (and Rust is here too) https://despairlabs.com/blog/posts/2025-07-10-an-openzfs-bug-and-the-humans-that-made-it/
An (almost) catastrophic OpenZFS bug and the humans that made it (and Rust is here too)

A couple of weeks ago I fixed a nasty bug in this function in OpenZFS:
