Paul McKenney has put together a series of articles on how to improve one's ability to give a good talk at a technical conference. On the other hand, (1) presentation skills stay with you through life, and (2) small improvements in presentation skills over months or years...

Intel's indirect branch tracking (IBT) is a hardware-implemented control-flow-integrity mechanism that makes it harder for an attacker to gain control of the system by way of a corrupted indirect branch. FineIBT is a software extension to IBT that is meant to improve its...

FOSDEM 2025 featured the usual talks about open-source software, but, as always, the conference also offered the opportunity to discover some more exotic and less software-centric topics. That's how I learned about the Flow Battery Research Collective (FBRC), which is...
The Gentoo Linux project has announced the availability of qcow2 images for amd64 (x86_64) and arm64 (aarch64), and plans to 'eventually' offer images for the riscv64 and loongarch64 architectures. The images, updated weekly, include an EFI boot partition and a fully...
One of the often-requested LWN site features that has languished the longest on our to-do list is full-text RSS feeds. We are happy to announce that, finally, there is a set of such feeds available; the full set can be seen on our feeds page. This is a subscriber-only...

The conversation around the merging of a set of Rust abstractions for the kernel's DMA-mapping layer has mostly settled after Linus Torvalds made it clear that the code would be accepted. One other consequence of this decision, though, is that Christoph Hellwig has quietly...
The Linux kernel supports attaching BPF programs to many operations. This is generally safe because the BPF verifier ensures that BPF programs can't misuse kernel resources, run indefinitely, or otherwise escape their boundaries. There is continuing tension, however, between ...

The kernel's slab allocator is responsible for the allocation of small (usually sub-page) chunks of memory. For many workloads, the speed of object allocation and freeing is one of the key factors in overall performance, so it is not surprising that a lot of effort has gone...
