Published 3D print & model files for a mounting bracket for the Leo Bodnar mini GPSDO device. These are commonly used in VHF+ amateur communications as 10 MHz references for use with timing-critical weak signal modes and for frequency-locking microwave & mmwave equipment.

I'm using the CERN-OHL-W license, which seems best for design files.

I do have a bunch of HV capacitors of uncertain vintage if anyone in the UK has a fun use for them.

🔔 The proposal notifications just went out for All Systems Go! 2025.
🙏 Thanks to everyone who submitted!
📆 Once we have the confirmations in, we'll publish the schedule.

The simple elegance of the Mac Mini is unmatched.

This graph is the one I'm most excited about: the lifetime of security flaws in Linux is finally starting to get shorter (and the number of fixed flaws continues to rise).

It took a long time and over 60 articles but, at @lwn, we have finally managed to complete our reporting from the 2025 Linux Storage, Filesystem, Memory Management, and BPF Summit. If you want to know what is going on in those core parts of the kernel, this is the place to look.

We've put together an EPUB version of the whole set as well — good bedtime reading!

1️⃣4️⃣ Here's the 14th post highlighting key new features of the upcoming v258 release of systemd. #systemd258

The concept of system credentials has existed since a while in systemd. It allows parameterizing the system (and the services running on it) in a secure and hierarchical way. You can pass them into containers and into VMs, for example via SMBIOS Type #11 vendor strings. While the transport is low-level and firmware compatible, they can reasonably only be consumed in userspace.

I've just released mount-insight v0.1 https://gitlab.com/zygoon/mount-insight/-/releases/v0.1

Here's an excerpt from the release notes:

This is the initial release of mount-insight, a tool created to explore and display the data provided by the statmount system call.
Some features are only going to work once Linux 6.15 is released. The code needs to see matching, up-to-date headers for userspace Linux APIs as well.

1/n

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.

I 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.
