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.

Setting goals is healthy, but aim for action over outcome.

Outcome: Complete a marathon.

Action: Exercise daily.

Whether you are a LocaleApp customer or not, this might be the perfect time for your Ruby on Rails startup to give LocaleData a chance. 🙂

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! ❤️

It's wild that the top deal for our national .sk domain comes from across the border – from Czechia.

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.

I'm a software engineering graduate, but man, do I love great design, illustration, photography, art, nature, and everything visual! 👌

I've upgraded all my sites to Rails 8.

Now I'm ready for 2025.

If you are using `has_secure_password` and have your own `password_reset_token` field, do not forget to disable the default one after upgrading to Rails 8:
