[$] Progress in modernizing kernel cryptography

At the 2026 Linux Security Summit North America, Eric Biggers spoke about some of the problems with the kernel's cryptography framework, as well as the recent progress in adding library APIs to allow developers to use cryptographic functions without using the traditional crypto API. He walked through a couple of examples to demonstrate the frailty of the original API and showed how the new library API made life easier for developers and kernel maintainers.

Single vs. Dual Channel Memory Performance With The Intel Core Ultra 7 270K Plus

Given today's pricing environment around system memory, a Phoronix Premium supporter recently requested some benchmarks to quantify the performance difference from single to dual channel memory. In considering a new computer build, he is contemplating whether to go for a single stick of DDR5 memory until memory prices hopefully subside in the future. For those in a similar boat, here are some benchmarks of single versus dual channel memory on an Intel Core Ultra 7 270K Plus "Arrow Lake" desktop.
