[$] Owning C types from Rust code

Rust's system of ownership and borrowed references is convenient when it can correctly model a program's needs. The Rust for Linux project has worked to provide adapters between Rust's semantics and the existing C code in the kernel. At Kangrejos 2026, Andreas Hindborg spoke about a patch series implementing the next such adaptor: an Ownable trait for representing objects that are allocated in C code, but which Rust code is responsible for cleaning up (if not necessarily deallocating) when it is done with them. He hoped to finally reach a consensus on the patch series, after months of discussion on the mailing list.

Eisentraut: The reverts will continue until morale improves

PostgreSQL core team member Peter Eisentraut has written a blog post reflecting on the "unusually high number of features" that have been taken out of the upcoming PostgreSQL 19 release since the beta period began. Some of the reverted features had significant architectural defects that would have been hard to fix quickly and during beta. But there was also a long tail of relatively harmless issues involving various edge cases. In past times, many of these would not have surfaced until much later and we would have fixed them bit by bit over the subsequent five years. But with LLM-assisted code review, these kinds of things can get found much faster, and then you're staring at a list of like forty defect reports. And even if each of them requires only a three-line fix on average, there is a fixed overhead to dealing with each of these, and then you run out of time. Most if not all of the affected reverted features were written a long time ago when LLM-assisted code review was not as use

Asterinas 0.19.0 released

Asterinas is a project to build a new operating-system kernel in Rust; it was covered here in 2025. Version 0.19.0 of the Asterinas kernel has been released; changes include a new graphics subsystem capable of running X.org, "minimal but usable" 64-bit Arm support, better virtualization support, and more.

Framework Laptop 12 Offers Improved Performance & Efficiency With Intel Core 3 Wildcat Lake

Last year Framework Computer launched the Framework Laptop 12 as a convertible, 2-in-1 laptop that was friendly with Linux and upgradeable inline with the beloved Framework Laptop 13 and 16 models. The initial Framework Laptop 12 was nice but the use of an Intel Raptor Lake U SoC in 2025 wasn't all that exciting. Now though Framework Laptop 12 is available with Intel Core 3 "Wildcat Lake" for offering better performance and power efficiency.
