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

We quietly released the code a little while ago but this is the official announcement of Capslock, our contribution to the supply-chain security conversation.

https://security.googleblog.com/2023/09/capslock-what-is-your-code-really.html

Capslock is a tool for understanding at high level what a given piece of (Golang) code is capable of and for detecting when an update to a library changes this capability set, to give users a chance to catch supply-chain attacks in progress.

After many hours, including re-capping the power supply (no dice, but worthwhile in any case), and tracing through most of the upper section, I finally found the issue with this Tektronix spectrum analyzer. A tantalum cap on the horizontal storage board failed and shorted the +15v bus. Replaced it and the SA seems to be working ok so far. #hamradio #amateurradio #electronics
