Instead of:

A hill I'm willing to die on

I'm gonna start saying:

A hill I'm having a picnic on

Just... spreading out a nice blanket with a basket of food and staying on that hill for a long long time

✅ too many ppl dying already
✅ picnics are cozy n nice
✅ nobody wants to eject someone having a nice picnic on a hillside, so you will probably win

Holy moly, #GNU sed was immensely faster than #FreeBSD's #sed with the exact same command.

The BSD sed was taking minutes and not finishing at all, only writing about 64KiB of the file per second.

GNU sed finished the entire 34MiB file in a few seconds.

Weird.

@mwl @dexter Ask me what my storage team thinks about this inability. And how many times a day I hear them express this opinion

SCSI is short for supercalifragilisticexpialidocious

A simplified history of regular expressions:

- In 1951, Stephen Kleene invented regular expressions.

- In 1966, Ken Thompson built the first software implementation of regular expressions, in the QED text editor for CTSS. UNIX ed is a cut down version of QED, popularizing the tradition of regular expressions in editors. grep started as a standalone version of the engine from ed. em, ex, vi, and vim evolved from ed.

- In 1987, Larry Wall spread regular expressions to the next generation of programmers through Perl. Gravely, it uses backtracking, spreading terrible performance for decades. It derives its engine from the rn newsreader, which derives it from Gosling Emacs. James Gosling told me he wrote it from scratch.

- In 2010, Russ Cox, having spent time at Bell Labs, rejected backtracking and built RE2, a fast and scalable engine, generalized from work on Google Code Search. Its ideas have spread to Go regexp and Rust regex, a new generation of engines. These engines dynamically select between specialized matchers, depending on the pattern.

- Since 2025, Ian Erik Varatalu has been researching regular expressions for his PhD and has produced a fast engine using symbolic derivatives. It implements seldom-included intersection and complement and efficiently implements lookaround, which had been exclusive to backtracking engines.

When passkeys first came out, I saw that they were tied to a particular device. I have many computing devices. I could use my password manager to store them but then, what advantage do they offer over my password manager? None.

Based on that, I decided against using them.

The post linked above goes into the technical details of how passkeys aren't for us.

For real world use, for someone who isn't a techie? Use a different password for each site. Either use a password manager or, if that's too complex, write it down in a book. On paper.

A nice discussion of passkeys.

They're for the company's convenience. They don't protect the user.

Initial support for ACPI in OpenBSD vmd (virtual machine daemon / hypervisor), adds the required tables for most modern OSes - Code by Mike Larkin mlarkin@ #OpenBSD #Virtualization https://github.com/openbsd/src/commit/c542173c8471e204b823acbb005697ed37e746a1

Recovering and reminiscing on an incredible #EuroBSDCon 2026 in Brussels, Belgium! 🇧🇪 😥

What a week! Over 234 attendees, 48 brilliant speakers, and 14 amazing sponsors came together to celebrate all things #BSD. The energy was #BSD, deep dives into tech, inspiring talks, and those hallway conversations that spark new ideas and collaborations.

Huge shout-out to the video crew who made sure every moment was captured, and to everyone who traveled near and far to be part of this vibrant community. Whether it was hacking, learning, or just geeking out over #BSD, the connections made here are what make this event so special.

Brussels, and the incredible Organizing Committee, you were the perfect host! Already counting down to the next one in Bratislava!

Did you attend? What was your highlight? 👇

We are collecting as much as possible on: https://2026.eurobsdcon.org/wrapup.html
