The LED deltoidal hexacontahedron is complete! 60 identical PCB sides covered with 3D printed diffusers. Two #Pixelblaze controllers work in sync to provide a fast frame rate for patterns on the 1200 LEDs.
When `ActiveRecord::RecordInvalid` gets raised, it actually keeps the record inside the exception. You can grab it with `exception.record`.
Had to use it recently and thought it was pretty cool! 😊

As announced at @rubykaigi today, I've been working on a new HTML-Aware ERB Parser that I just released today.
Introducing Herb — a fast, modern, and HTML-aware ERB parser, designed from the ground up for smarter developer tooling.
Ruby 3.4.3 Released https://www.ruby-lang.org/en/news/2025/04/14/ruby-3-4-3-released/.
This is a routine update that includes bug fixes. We recommend upgrading your Ruby version at your earliest convenience.
Giving my talk at #RubyKaigi today on my newest SQLite project—Plume. Plume will be a suite of tools for working with SQlite elegantly, and the first major tool is a parser that is 100% compatible with SQLite source. Excited to share more today!

On pikoin (my small personal finance tracker) I'm using SQLite, so I don't have to worry about N+1, I'm just building data structures in Ruby even if the process triggers 30 or more database queries.
If there's one thing I'd like to see in the Rails ecosystem is a UI kit made by a designer. Or have a designer on the team.
I know us developers like to dabble in design but my perspective was always that we won't sweat that much on the small details as a designer will.
Do I know anyone hiring iOS engineers?
Hey #rubykaigi attendees, the conference is coming, and I have no plan for Day2/Day3 lunch and Day2 dinner. I'd love to talk with Rubyists, especially those from abroad, so please let me know if you can hang out with me!
