The end of OzLabs

OzLabs is a collection of Australian free-software developers that was, for most of its history, associated with IBM. Members of OzLabs have included Hugh Blemings, Michael Ellerman, Ben Herrenschmidt, Greg Lehey, Paul Mackerras, Martin Pool, Stephen Rothwell, Rusty Russell, and Andrew Tridgell, among others. The OzLabs "about" page notes that, as of January 2026, the last remaining OzLabs members have departed IBM. "This brought to a close the Ozlabs association with IBM". Thus ends a quarter-century of development history.

PostgreSQL contributor Robert Haas has published a blog post that breaks down code contributions to PostgreSQL in 2025.

I calculate that, in 2025, there were 266 people who were the principal author of at least one PostgreSQL commit. 66% of the new lines of code where contributed by one of 26 people, and 90% of the lines of new code were contributed by one of 67 people.

Contributions to the project seem to be on the upswing; in his analysis of development in 2024, there were 229 people who were the primary authors of a commit, and 66% of new lines of code were contributed by one of 18 people. The raw data is also available.

[$] Task-level io_uring restrictions

The io_uring subsystem is more than an asynchronous I/O interface for Linux; it is, for all practical purposes, an independent system-call API. It has enabled high-performance applications, but it also brings challenges for code built around classic, Unix-style system calls. For example, the seccomp() sandboxing mechanism does not work with it, causing applications using seccomp() to disable io_uring outright. Io_uring maintainer Jens Axboe is seeking to improve that situation with a rapidly evolving patch series adding a new restrictive mechanism to that subsystem.

Version 11.0 of the Wine Windows compatibility layer is out. "This release represents a year of development effort, around 6,300 individual changes, and more than 600 bug fixes." The most notable changes in this release are support for the NTSync Linux kernel module (when available), and the completion of the Windows 32-bit on Windows 64-bit (WoW64) architecture that was announced as experimental in Wine 9.0.
