After the Rubygems drama, I felt frustrated that I can’t escape evil people trying to dominate my life.
I found myself mourning the future I thought we would have; but also hopeful that it’s not too late to start choosing kindness.

I bought this this morning and I’m over half way through it. Probably the best $25 I’ve spent in years. I use web components for my blog posts and have known for a while that there are big gaps in my knowledge, and this has filled a whole bunch of them.
Online on a weekend? You can grab access to my web components course for $25 today and tomorrow. Big ol’ discount. Use the code OCT25-26.

Once you realize the web is really just a giant game / graphics engine that gives you a DSL for content, and a DSL for styling, and a scripting language for anything extra...it all kinda starts to make sense.
the "scripting" language is the escape hatch for the cases the DSLs can't handle.
