So we merged this → https://github.com/systemd/systemd/pull/28891 into systemd today. I like to believe that this is a major step towards closing the "TPM gap" we have on Linux toward other OSes. It can automatically generate an automatic TPM2 PCR policy from various inputs covering the PCRs that generally are hard to predict by the OS vendor, i.e. things like local firmware versions, extension cards and so on. It stores this in an NV index in the TPM. Things like LUKS can then be locked against that NV index.

Working on some long-needed updates to my 1.2m dish setup. Mounting an azimuth sensor (ETS25 absolute encoder) directly under the Az slew drive. A previous belt-driven version was too complicated. This is all upside down, btw. #amateurradio #hamradio #radioastronomy #electronics #microwave

Made some millimeter waves today, presumably at 47.088 GHz. Using a Kuhne synth at 11.772 GHz into a WA1MBA quadrupler. I’m able to detect power in this band (6mm), but not frequency (yet). #microwave #mmwave #hamradio #amateurradio.

Ran a full disk threat scan on my Mac with MS Defender ($work requires it), and it found my archive of Linux malware from 1997, and wants to delete it :(

We recently added a new document to the systemd website focussing on one specific facet of the service manager: the fdstore. A concept that people should really use more to facilitate "seamless" service restarts and various other things. Please have a look:

I'm very excited to announce that you can now try online!
The new demo environment uses Incus virtual machines running on a remote Incus cluster with full support for both containers and VMs!

Reminder: we maintain a kernel feature wishlist here as part of the uapi group:

https://github.com/uapi-group/kernel-features

I just added a bunch of new entries to it (at the bottom). If you are looking for something to hack on (and have some kernel expertise, or would like to acquire it), would be more than excellent to work on those!

Saw a lot of Aurora flying over Greenland on the way to Linux Security Summit EU. This is the best I could do with an older iPhone #linux #linuxsecuritysummit #space #spaceweather #hamradio #amateurradio
