LWN editor Jonathan Corbet was asked to give a brief talk about kernel maintainership at the recently concluded Linux Foundation Member Summit. That talk was recorded and has now been made available on YouTube. There is little in it that will be news to regular LWN readers,...
Matthew Garrett explains why ACPI exists and why it is not as bad a thing as some think. There's an alternative universe where we decided to teach the kernel about every piece of hardware it should run on. Fortunately (or, well, unfortunately) we've seen that in the ARM...

A fast-moving patch set—seemingly the norm for Linux networking development—seeks to add some Rust abstractions for physical layer (PHY) drivers. Lots of review has been done, and the patch set has been reworked frequently in response to those comments. Unfortunately,...

The New Stack covers a conference talk by Bjarne Stroustrup on turning C++ into a safer language. Stroustrup has arrived at his solution: profiles. (That is, a set of rules which, when followed, achieve specific safety guarantees.) They’d be defined by the ISO C++...
The 6.6 kernel was released, right on schedule, on October 29. This development cycle saw the addition of 14,069 non-merge changesets from 1,978 developers — fairly typical numbers for recent releases. The time has come for LWN's traditional look at where the changes in...

For a view into the OpenBSD approach to security, see this message from Theo de Raadt, where he describes a plan to remove the syscall() system call (which allows the invocation of any available system call by providing its number) from the kernel. The purpose, of course, is ...
