Kernel prepatch 5.15-rc2 The 5.15-rc2 kernel prepatch is out for
testing.
So I've spent a fair amount of this week trying to sort out all the
odd warnings, and I want to particularly thank Guenter Roeck for his
work on tracking where the build failures due to -Werror come from.
Is it done? No. But on the whole I'm feeling fairly good about this
all, even if it has meant that I've been looking at some really odd
and grotty code. Who knew I'd still worry about some odd EISA driver
on alpha, after all these years? A slight change of pace ;)

[$] More Rust concepts for the kernel The first day of the Kangrejos (Rust for Linux) conference introduced the project and what it was trying to accomplish; day 2 covered a number of core Rust concepts and their relevance to the kernel. On the third and final day of the conference, Wedson Almeida Filho delved deeper into how Rust can be made to work in the Linux kernel, covered some of the lessons that have been learned so far, and discussed next steps with a number of kernel developers. | | 10:40p |
Hoyt: Structural pattern matching in Python 3.10 Ben Hoyt has published a critical
overview of the Python 3.10 pattern-matching feature.
As shown above, there are cases where match really
shines. But they are few and far between, mostly when handling
syntax trees and writing parsers. A lot of code does have
if ... elif chains, but these are often either
plain switch-on-value, where elif works almost as well, or
the conditions they’re testing are a more complex combination of
tests that don’t fit into case patterns (unless you use awkward
case _ if cond clauses, but that’s strictly worse than
elif).
(Pattern matching has been covered here as
well). |
