[$] Native support for Rust on the GPU

Christian Legnitto is the maintainer of rust-gpu and Rust CUDA, two libraries that make it possible to program a computer's graphics processing unit (GPU) from Rust. He isn't satisfied with the current state of GPU support in Rust, however. In a talk at RustConf 2026, he explained his vision for how the GPU could become an ordinary compiler target for normal Rust code, without the need for any special libraries or new ecosystem support. That vision is not yet fully implemented, but he does have a prototype that he is preparing to release.

Ubuntu 26.04 upgrades from 24.04 are now enabled

It’s taken longer than expected, but users can now upgrade to Ubuntu 26.04 from 24.04 directly, without command-line workarounds.

Destroy any website (browser game, but cathartic)

Destroy Any Website is a browser-based run-and-gun that lets you run amok on any public-facing website. You take command of a character and access a variety of weapons. The aim is to score points by blasting your chosen target to literal pieces. Run, jump and jetpack around the site elements using WASD controls and take aim using your mouse. A competitive multiplayer mode lets you pick a website, share a code with a pal and then compete to reach a destruction score, replete with scoreboard. Lest anyone panic, the wanton destruction the in-browser game can unleash is done on a […]

[$] The kernel from a PostgreSQL point of view

Andres Freund has a few claims to fame, but chief among them is his many years of work to improve the performance of the PostgreSQL relational database management system. That work requires working with β€” or around β€” many Linux kernel features and behaviors. He put in an appearance at the 2026 edition of Kernel Recipes to talk about his experience working with the kernel project, how the kernel could better support applications like PostgreSQL, and some interesting developments in the PostgreSQL world.
