The other day I was thinking about some of the people who I used to follow in the old blue bird site. A few of them did open accounts here on Mastodon, mostly because it was "trendy" at that time, but most (of those few) eventually left their accounts to rot. A lot of people from the old site […]

My 2025 in (very brief) review.
In January I had a feeling this was going to be a very long year, for no particular reason at all, it was just a gut feeling.
In July I was "whoa! already?".
But now that we're here, on the very last day, looking back I can confirm it was a very long year.

It's funny how there are 40 Mph (65 Km/h) wind gusts right before a 30 F (16 C) temperature drop (from 55F/13C to 25F/-4C). It's like if nature turned on the AC on max. 🌬️☃️

The idea of Matrix as a chat service is nice. But the fact that it keeps going out of sync, and I keep losing messages from other people is just plain annoying. This is worse than IRC net split (at least there was a message when it happened).

pro tip: a Homelab and Selfhosted infra are two different things.
If you use your #homelab for #selfhosting your personal stuff, one of two things happens:
- you can no longer use your homelab as homelab and for experimentation
- your selfhosted infra is constantly offfline

Gran Turismo 7 on PlayStation VR2 is just mind blowing. I think that's the first racing game that I can drive without struggling. The 1st person view in VR makes it a lot easier. And the best part: no motion sickness at all.

She saw the future and saved us *thousands* of Dollars. 😄

You don't have to deal with packages in Bazzite. It's all Flatpak and Homebrew. You will very rarely have to even think about RPM at all, only very specific corber cases.
