FileVault mysteriously re-enabled after Tahoe 26 -> 26.1 upgrade. Wonderful !
Why Wonderful ! - It turns off remote connections.
Time to grab a keyboard and monitor and logon to each Mac and reconfigure so I get remote access back.

Affinity Photo has always been a good value rival to Photoshop. I have been using it to edit my photos for 10 years.
Now Affinity Photo is part of Affinity Studio and it is free. You only pay if you want the Canva AI features.

Fun and games with the Raspberry Pi Imager. The current release 1.9.6 does not allow username / password login over SSH.
Took several hours to find the solution.
Solution: Downgrade to 1.8.5.

Always good to hear @scott.hanselman.com speak. This talk is fantastic covering tech; what was promised, what was delivered and how we need to assess what we consume.
I just wanted to say, I’m probably more proud of this Ted talk than just about anything I’ve ever done so I’m gonna be absolutely useless for the next couple of weeks as I promote the shit out of this because I want you to watch it because it matters in the moment we are in youtu.be/dVG8W-0p6vg
