Ruby 3x3 announced that Ruby 3.0 would be three times as fast as Ruby 2.0. It was an audacious goal, especially for a language released in 1995.

In this series I’ve built out a Rails app from scratch, deployed it and I’m this close to getting it actually useful.

Will today be that final bit to hit “useful?” I don’t know as I write this, but it’s getting closer…

In this series I’ve built out a Rails app from scratch, deployed it and I’m not too far off from getting it actually useful.

I’ve also had a nice photo shoot with my stuffed animals so the site’s a lot prettier.
