LXD 3.15 released
The LXD team has announced the release of LXD 3.15. "One
big highlight is the transition to the dqlite 1.0 branch which will bring us
more performance and reliability, both for our cluster users and for standalone
installations. This rework moves a lot of the low-level database/replication
logic to dedicated C libraries and significantly reduces the amount of back and
forth going on between C and Go."
[$] Who's afraid of a big bad optimizing compiler?
Our increasingly aggressive modern compilers produce
increasingly surprising code optimizations. Some of these optimizations might
be especially surprising to developers who assume that each plain C-language
load or store will always result in an assembly-language load or store.
Although this article is written for Linux kernel developers, many of these
scenarios also apply to other concurrent code bases, keeping in mind that
"concurrent code bases" also includes single-threaded code bases that use
interrupts or signals.

[$] 5.3 Merge window, part 1
As of this writing, exactly 6,666 non-merge changesets have
been pulled into the mainline repository for the 5.3 development cycle. The
merge window has thus just begun, there is still quite a bit in the way of
interesting changes to look at. Read on for a list of what has been merged so
far.
