Oh yeah, I already mentioned this a while ago but I also added support for pidfds in Linux coredumps.
/proc/sys/kernel/core_pattern has been extended so userspace can instruct the kernel to install a pidfd for the
crashing process into the usermode helper process, e.g., systemd-coredump.

l0kod@mastodon.socialI released a new version of the #Landlock crate: https://github.com/landlock-lsm/rust-landlock/blob/HEAD/CHANGELOG.md#v042
We can now easily restrict signal sending and connections to abstract UNIX sockets for #rustlang programs. The documentation and tests have also been improved. Last but not least, a few new features will be useful for the upcoming Landlock configuration format.

jmorrisIf you answered other, please feel free to explain.
In honor of this landslide vote, here's a photo of my latest tinkering: making pipecap filters for an 11 GHz RF multiplier (using the W1GHZ board & design). I'll use brass M3 tuning screws once some arrive from McMaster-Carr, although I'd be interested to see if they are very different to stainless steel. And yes, I had to order them online after not finding any metric brass fasteners locally. Why not use SAE screws? Standard metric screws have much higher TPI, even more than fine-thread SAE. This will provide better mechanical stability & finer tuning, but then again, I'm not building a spaceship here, so 🤷

Telegraph poles like these, with multiple "code lines", were once a common feature along American railroads. They are distinguishable from ordinary power or telephone lines by their multitude of cables, often occupying several crossarms. They typically carried a power bus plus individual lines for the signals along the route, with more efficient encodings used as technology improved.
They've been mostly supplanted by more modern SCADA systems that don't require so many individual wires.
