This is also your weekly reminder that Fedora comes out of the box with zswap and zstd root file system compression.

What you see above is me extending a timachine snapshot disk (defrag adds comp) over smb to backup our laptops to a little Thunderbolt drive on Fedora.

For @mattdm.org as always.

Just sent an email to my dad who used to be a legit professional trombone player about listening to Radio2 playing brass band music, but now with added techno.

The opensource tech to send music to the kitchen and the library from England and all be in sync has me quite teary eyed.

Spending decades running β€œbig computer” at β€œfancy ass organizations”, now being the tester for projects like this make me think of busting out a proper @kelseyhightower.com inspiration post.

It’s not about the size of the market, it’s all about the people you meet along the way.

Yo Dawg,

We heard you like Claude, so we put Claude in your containers to contain Claude so it contains your containers that Claude’s gonna find a rootkit to bust out your containers.
