An interesting article about how the Facebook team debugs the Linux Kernel at scale. With the drgn tool, they can obtain stack traces from crash dumps, etc.

There is a lot of cleanup activity (see example) in the Yocto project to either upstream or remove old patches. If you know of patches that need upstreamed, please help out!

The Yoe Distro has updated support for the Graphics drivers for the BeagleBone Black. Qt5 and other apps now work again. See several relevant PRs: 622, 623, and 627.

Quickemu is an excellent tool for launching a wide variety of different operating systems quickly, including most Linux distributions, Windows, and MacOS. Try it out -- it is very neat.

Discovered some more tools for the terminal. All written in Rust, which seems to be a trend.
