I followed tech twitter over to this place. I like old video games and computers.

I think a fundamental problem is that my brain is all map and no reduce.

I don't know who needs to hear this - but `tar` has a handy flag (`-S`) for compressing sparse files. If you don't use it when compressing VM volumes, you may end up filling a disk unintentionally and wondering where 80 GB of data suddenly came from.

Are people really running `kubectl apply -f $random-github-url` when they see it on random blogs?

Thanks to AI, I’m constantly worried about putting em dashes in my writing now. How am I suppose to give everyone the bonus context they need?

Vibecoding today instead of my usual copy/pasting chunks of code into Claude and asking for feedback. Its neat, but feels weird.

If I code predominantly with AI output -- am I actually writing software? Am I copying someone else's work? Can I look back and say "I did this"? Does it matter?

On Amazon, your digital marketplace can be different than your physical goods marketplace. If your digital library (kindle, etc) is set to another country, lots of stuff mysteriously fails. In my case, I couldn't get Libby or Audible to work at all.

Okay, I'm several days into bsky and I love the simple timeline view of the world. I'd forgotten how much less chaotic this feels.
