Lots of recent picolibc news:

* Oliver Stannard at ARM got testing running on the FVP emulator for more rigorous AARCH64 validation.

* Eduard Tanase fixed a bunch of documentation issues.

* Joel Holdsworth added OpenRisc support.

* Jiaxun Yang fixed my janky tools situation by creating picolibc-ci-tools which auto-builds all of the extra bits we need for CI. They also add LoongArch and LatticeMico32 support. The latter uncovered GCC bugs which I had fun fixing.

Thanks to all of you!

Dumb legal question: if people generally do not read terms of service type documents, how are they valid as a legal vehicle?

util-linux has merged support for statmount() and listmount() to list mounts:
https://github.com/util-linux/util-linux/pull/3092#event-15865684400

This should be a nice performance improvement.

See https://brauner.io/2024/12/16/list-all-mounts.html for some details on listmount() and statmount().

Here's a brief blog on my amateur radio publications last year: https://w7txt.net/2024/12/29/publications-in-2024/

- Investigating the Extended Frequency Range of the WA1MBA Millimeter Wave Quadrupler.

- Open Source Arduino Controller for Surplus Flatpack2 PSU.

I've written a post that shows how to list all mounts in all mount namespaces (all mounts on the system) using new apis we added to the last year.

1️⃣9️⃣ Here's the 19th post highlighting key new features of the upcoming v257 release of systemd.

A relatively basic feature of systemd's service management is the ability to automatically restart a service in case it terminates unexpectedly, configurable via the Restart= setting.

In v254 we added the RestartMode= setting that allows to fine tune the mechanism to use for restarting the service, i.e. it adds a logic to optionally avoid marking the service as failed between…

@spacetelescope definitely worth clicking through: the image holds a second discovery that’s easier to overlook. Examine the white elliptical galaxy at left. A faint red arc appears in the inset at 10 o’clock. This is a very distant galaxy whose light is bent by the gravity of the elliptical foreground galaxy – and its appearance is duplicated. The stretched red arc is warped where it reappears – as a dot – at 4 o’clock. These images of the lensed galaxy are so faint and so red that they went unrecognized in Hubble data, but are unmistakable in Webb’s near-infrared image.

I've been seeing slow downloads from #Fedora mirrors yesterday & today, pretty sure my Internet connection is ok. Anyone else seeing this?

8️⃣ Here's the 8th post highlighting key new features of the upcoming v257 release of systemd.

A longer time ago systemd introduced JSON based user records as an extension of classic UNIX `struct passwd`. These records can be provided via Varlink IPC or via drop-in files. The much richer set of account settings is documented here:
