FOSS Weekly #22.37: Free Ubuntu Pro, Kernel 6.0, TUXEDO OS, Crossword, Btrfs and More
After several weeks, I published a new video on YouTube. Videos take quite some effort and I am not a fan of videos.
However, I know many people prefer videos to text articles. What do you prefer?

Plop Boot Manager boots PCs off media they can't start from • The Register
Elmar Hanlhofer's Plop Boot Managers are a small family of tiny tools to enable booting from media that a computer can't usually boot from.
Before you point out that all modern computers can boot from USB – the boot managers also work well in virtual machines, where USB boot support is still a lot rarer. Yes, of course, you can virtually "insert" an ISO file into your VM's virtual CD-ROM, but if you want to boot a VM from a real physical USB key, it's not so easy.
The programs are tiny: they fit onto a single floppy disk (even a 720kB one), and the ISO image is about half a megabyte.
[...]
The original Plop Boot Manager, currently on version 5.15, and the new, still in development, PBM6 are freeware, but they're not open source. Saying that, though, both are free to use for both personal and commercial purposes. They also have a Linux-only relative, PlopKexec, which is fully open source.

OpenStack 'SLURP' ends requirement for six-monthly upgrades • The Register
OpenStack has completed an alphabet’s worthy of releases, with the project on Wednesday issuing “Zed” – the 26th version of the open-source cloud stack and also adding an optional slower upgrade cadence.
The stack’s 41 sub-projects – from adjutant to zun - each publish release notes and there are too many changes to mention or summarise.
The OpenStack project has chosen to highlight the addition of OAuth 2.0 to the Keystone authentication service, Cinder now allowing users to transfer encrypted volumes across projects, and support for Xilinx FPGAs in the Cyborg accelerator support framework. The Nova VM-wrangler can now support IOMMU, which means VMs get direct access to memory if needed.
