OpenBGPD 8.9 released
Claudio Jeker (claudio@) announced the release of version 8.9 of OpenBGPD, the OpenBSD project's Border Gateway Protocol (BGP) daemon:
We have released OpenBGPD 8.9, which will be arriving in the OpenBGPD directory of your local OpenBSD mirror soon. This release includes the following changes to the previous release: * In verbose mode log the NOTIFICATION data for UPDATE errors. * Fix a busy loop error in the pfkey handling for OpenBSD and FreeBSD. * Introduce monotime - an internal time API using microsecond resolution. * Fix accounting of the pending update counter * Use new ibufq interface instead of handrolling the same. * Large refactoring of internal APIs to make the code easier to share and cleaner.[$] Jumping into openSUSE Leap 16
The openSUSE project is nearing the release of Leap 16, its first major release since openSUSE Leap 15 in May 2018. This release brings some changes to the core of the distribution aside from the usual software upgrades; YaST has been retired, SELinux has replaced AppArmor as the default mandatory access control (MAC) system, and more. If all goes according to plan, Leap 16 final should be released in early October, with planned support through 2031.

Cuni: Tracing JITs in the real world @ CPython Core Dev Sprint
Adding a JIT completely changes how we reason about performance of a given program, for two reasons:
- JITted code can be very fast if your code conforms to the heuristics applied by the JIT compiler, but unexpectedly slow(-ish) otherwise;
- the speed of a given piece of code might depend heavily on what happens elsewhere in the program, making it much harder to reason about performance locally.
The end result is that modifying a line of code can significantly impact seemingly unrelated code. This effect becomes more pronounced as the JIT becomes more sophisticated.
Cuni also gave a talk on Python performance, which LWN covered, at EuroPython 2025 in July.

Fedora considers an AI-tool policy
You are responsible for your contributions. AI-generated content must be treated as a suggestion, not as final code or text. It is your responsibility to review, test, and understand everything you submit. Submitting unverified or low-quality machine-generated content (sometimes called "AI slop") creates an unfair review burden on the community and is not an acceptable contribution.

PostgreSQL 18 released
Version 18 of the PostgreSQL database has been released. Notable improvements in this release include "skip scan" lookups for multicolumn B-tree indexes, virtual generated columns, better text processing, oauth authentication, and a new asynchronous I/O (AIO) subsystem to improve performance:
AIO lets PostgreSQL issue multiple I/O requests concurrently instead of waiting for each to finish in sequence. This expands existing readahead and improves overall throughput. AIO operations supported in PostgreSQL 18 include sequential scans, bitmap heap scans, and vacuum. Benchmarking has demonstrated performance gains of up to 3x in certain scenarios.There are, of course, many other improvements and changes; see the release notes for full details.
