A red box with the ARC Studio product sitting on a brown desk. 

ARC Studio is a hardware box that helps with calibrating studio monitors to the room they sit in. Basically to make the sound coming out of the speakers more balanced across the frequency range.

Can’t wait to get rid of the SoundId Reference system-wide plugin. Nothing but trouble with it for the past couple of years.

I am hoping a hardware box willl bring more stability to the system.

Maybe OT: If anyone interested and stay few days before/after the conference we could do a climbing trip :) πŸ§—There a ton of climbing areas close by, thousands well-bolted sport routes.

El Chorro for example - also a great place to go for a hike or to see the famous Caminito Del Rey ✨

After a whole day inside, I went outdoors only to find out that my street had turned into a winter post-apocalyptic scene. Got scared for a moment :D

The snow is artificial.

Hey bksy, I’m on the look out for my next project, I’m an experienced Elixir dev (> 8 years commercially, and > 10 years of Ruby before that + I'm still the maintainer of RSpec), very familiar with Phoenix and LiveView, and have enough CSS / JS knowledge to approach projects from a full stack angle.

Thank you for everything! ❀️

After years of working with RoR I was not happy with the state of things (the Rails way), I started looking into alternatives in 2018.

dry-rb and ROM played an important role in showing me the FP approach and it ended up with me moving to Elixir.

You opened that door
