Really every theorem should either describe what it does or have ten thousand names, chained by hyphens, going back to an early hominid named Garg.

Dr Becky, PBS Space Time and Angela Collier all release on the same days. Giving me one big day filled with quality astro physics. But leaving all other days devoid of good content. It would be nicer if they staggered a little.

Posting here for a lack of !verymildlyinconvenient.

Hi all!

I have a Debian stable server with two hdds in a md RAID which contains an encrypted ext-4 filesystem.

sda          8:0    0   2.7T  0 disk
├─sda1       8:1    0     1G  0 part                    
│ └─md0      9:0    0  1023M  0 raid1 /boot             
├─sda2       8:2    0   2.7T  0 part                    
│ └─md2      9:2    0   2.7T  0 raid1                   
│   └─mdcrypt

I'd like to migrate that over to BTRFS to make use of deduplication and snapshots.

But I have no idea how to set it up since BTRFS has its own RAID-1 configuration. Should I rather use the existing MD array? Or should I take the drives out of the array, add encryption and then add the BTRFS RAID inside that?

Or should I do something else entirely?

I migrated my wife's PC after a forceful Windows 11 update to Linux. I made a backup of her files by doing an rsync of almost the complete C: drive onto an external drive formatted with exFAT. This was a grave mistake.

After the Linux installation we noticed that several files were missing and older files were back. My current guess is that I was somehow copying from an old snapshot instead of the current state.

I rsynced everything except for the Windows folder. Does anyone know if there is any chance of getting our filea back? Amd what actually happened?

Edit: After several weeks I finally found the answer. There are two drives in the laptop. But Linux didn't see the NVME drive because it does not support "RST with Optane". As soon as I switched the SATA mode over to AHCI I could see the system drive with the lost files.

to see that AIs have as many problems as they do with drawing hands.

With every version of Android it seems to be harder and harder to get real time notifications anywhere near real time.

Twitch notifications, Signal, WhatsApp, I often get these ten to thirty minutes too late.

I've excluded them from battery optimisation but that doesn't seem to do anything. And I can't find anything else.

I don't care about battery usage. I'm always near a charger.

Android 13 on a Fairphone 3.

Edit: I've disabled DOZE according to https://stackoverflow.com/questions/40204605/android-completely-disabling-deviceidle-doze-in-android-m Hopefully that helps.

FOSS AI painting with Krita

It's so awesome that I can let my kid paint with Krita and let her enhance the picture with AI live. She wanted to have an AI picture editor on her phone but I didn't like the privacy policy. But Krita AI Diffusion came to the rescue.

After testing it out myself I showed her Krita, the most important tools and how to use layers and before I could say anything she was off to paint a nice landscape. When she was finished I actually got to enable the AI plugin and show her the ropes around that. And after enabling live painting she went ham and added a phoenix and a giant hand.

Hardest thing about it was that she had to describe what she wanted in English. But she's already learning that in school so it shouldn't give her too much trouble in the long run.

Anyways, FOSS rules!
