"'This release remains on track, nothing special to report. The biggest patch here is for the AMD microcode signing snafu[1], other than that it all looks entirely regular with small fixes spread fairly normally across the board.

NGC 1499: The California Nebula

Explanation:
Could Queen Calafia's mythical island exist in space? Perhaps not, but by chance the outline of this molecular space cloud echoes the outline of the state of California, USA. Our Sun has its home within the Milky Way's Orion Arm, only about 1,000 light-years from the California Nebula. Also known as NGC 1499, the classic emission nebula is around 100 light-years long. On the featured image, the most prominent glow of the California Nebula is the red light characteristic of hydrogen atoms recombining with long lost electrons, stripped away (ionized) by energetic starlight. The star most likely providing the energetic starlight that ionizes much of the nebular gas is the bright, hot, bluish Xi Persei just to the right of the nebula. A regular target for astrophotographers, the California Nebula can be spotted with a wide-field telescope under a dark sky toward the constellation of Perseus, not far from the Pleiades.

Our nearest decent size town (Pikeville, KY) got hammered with the #flood today. We're fine; our house is a reasonable distance above the creek, but our road got messed up and all the local towns that are built down on the riverbanks got decimated. Somebody just sent me this video in a group message on Signal:

I am back on Qtile and using Picom as my compositor. How do you prefer to manage all you dot files? just have a seperate git repo for each that you want? Or just a general dots repo? I've been wanting to get more comfortable with git. Such as gitignore and what not. I typically just do a dots repo or a specific repo for the subject/package.

AppArmor out, SELinux in for openSUSE Tumbleweed.

Very happy to announce my book The Linux Memory Manager is now available to pre-order at

https://nostarch.com/linux-memory-manager

It's a comprehensive 1,300 page exploration of how memory functions in Linux that goes into great depth on the subject, and is the first book of its kind for 20 years :)

How to speed up your phone for free - tested guide, it works!

1. Enable KASAN and other kinds of instrumentation while debugging your phone's kernel.
2. Notice how it makes things slower, but not slow enough to be unusable.
3. Keep using the phone this way.
4. Get used to it and forget that these things are enabled.
5. Many months later, get back to stock kernel config while doing something unrelated and enjoy your newly unlocked extra performance! 😝

I always wanted a simple way to put the phone to silent mode when e.g. placing it on the table next to the 🛏️ . Since Biemster got NFC to work on the Oneplus 6/6T (https://github.com/biemster/pmos-openbox-conky/blob/main/nxp_nci_i2c.py) we can leverage that and have feedbackd's profile adjusted when certain RFIDs are seen (https://source.puri.sm/Librem5/feedbackd/-/merge_requests/154). For this to land we want to move the NFC support from a python script to s.th. like nfcd (https://github.com/biemster/pmos-openbox-conky/pull/18#issuecomment-2653920089). Help on this would be appreciated.

Did you know that in the early 1990s, shortly before the first smart phones dropped, "smart calculators" were poised to become the hubs of our of digital lives?

Here's a photo of one such device from Casio. For more calculator history, check out https://lcamtuf.coredump.cx/blog/calculators/
