=> ↺ Looking forward to Akademy 2023
In less than 50 hours from now Akademy 2023 will start in Thessaloniki, Greece, with plenty of things to look forward to.
After having missed last year and the two previous ones having been online only, it’s the first in-person Akademy in four years for me.
While I have been at a couple of events in the recent months, there’s still a number of people I haven’t been able to meet again in person since Akademy in Milan, so this is all long overdue.

Hey folks,
I’m so thrilled to introduce you to our team’s recent new hires. This week, we’re joined by 3 new folks and here’s a bit of an intro from the 3 of them:

=> ↺ Haiku Activity & Contract Report, June 2023
The biggest changes last month were a series of commits by waddlesplash, all related to the user_mutex API and the consumers of it. This API is the kernel portion of the implementation of basically anything related to mutexes or locks in userland, including pthread_mutex, pthread_cond, pthread_barrier, unnamed semaphores (via sem_open), rwlocks, and more. It bears some resemblance in concept to Linux’s futex API, but is very different in both design and implementation.
=> ↺ Introduction to immutable Linux systems
If you reach this page, you may be interested into this new category of Linux distributions labeled "immutable".
In this category, one can find by age (oldest → youngest) NixOS, Guix, Endless OS, Fedora Silverblue, OpenSUSE MicroOS, Vanilla OS and many new to come.
I will give examples of immutability implementation, then detail my thoughts about immutability, and why I think this naming can be misleading. I spent a few months running all of those distributions on my main computers (NAS, Gaming, laptop, workstation) to be able to write this text.
=> ↺ Some notes on errno when tracing Linux kernel system call results
Suppose, not entirely hypothetically, that you want to print out some information about every fcntl() lock call that fails, system-wide. These days this is relatively easy to do with bpftrace, especially since there are system call entry and exit tracepoints. However, you might reasonably wonder how the fcntl(2) system call actually returns errno, the error code, and how this manifests at the level of the sys_exit_fcntl syscalls tracepoint. As it turns out, there's some tribal knowledge and peculiarities here.
