Coffee lovers, have you tried cascara?
I had one yesterday for the first time, got a sample from a local roastery. It's quite unique and fruity. I need to experiment with the dosage, but so far, it's not the most interesting thing I've tried. I think I'll stick with the beans.

I made my first commit to a Rails app over 12 years ago.
At that time, I was a university student looking for a framework my classmates and I could use for our team project.
Little did I know that Rails would become my favorite stack, shaping my career for the next decade.
Thank you, Rails! ❤️

If you put a drop in a bucket every day, the bucket's going to have some water in it.
If you collect modest drops of meaningful effort for 365 days, you'll end the year with a bucket that's pretty full.

I'm slowly migrating my Rails apps from Sidekiq and Redis cache to the Solid Trifecta, especially the low-traffic ones. Ditching Redis should simplify things. So far, so good!

Once I forgot to enable the Hetzner firewall for a new VPS.
A Redis instance on this server was left open to the public because I relied on the firewall being enabled. At that time, I didn't know that UFW doesn't work with Docker out of the box.
