in the spirit of open source, if you'd like to critique one I've written before it goes out, you can do so here https://github.com/spinel-coop/spinel.coop/pull/4
I've been enjoying jj immensely so I wanted to write up everything you need to know about my experience
https://kaspth.com/posts/an-in-depth-look-at-my-jj-experience
I gave my first conference talk 2 years ago today on my design technique riffing.
I still use it all the time, and I honestly think it's even more valuable in the age of AI. You don't have to give up intention & learning to achieve speed.

Really fun getting to see a write up of the Martian's Gemfiles
https://evilmartians.com/chronicles/gemfile-of-dreams-libraries-we-use-to-build-rails-apps
It's also an honor to get the shoutout and sample code in there ❤️
I'm back on @deadcode to talk about the impactful Open Source I've done since Rails core.
We get into what these gems are and the philosophy behind them.

Is this too much indirection?
Context: since Associated Objects let you write smaller objects, having Mailers with one action becomes common. And then the Mailer becomes mostly plumbing.
Eventually I'd love rv to have a built-in matrix command, so we could do stuff like
rv matrix 3.2+ run "<script code>"
and have it print out the results on the terminal
I was verifying whether Symbol#to_proc called private methods. I remembered it as doing so, but it doesn't! And at the very least hasn't done so since 3.2.
I verified this with:
class Hello; private def yo = :yo; end
:yo.to_proc.call Hello…
Here's a nice rv win. Because Ruby installs take seconds it was super easy to verify behavior across many Ruby versions.
So I can just swap out the version and run my test code in irb like this:
rv run --ruby 4.0 irb
some odd ones on the guestbook, but I kinda like the silly ones too lol https://kaspth.com/guestbook
thank you to people who've signed it!
I've been really impressed with the kindness and support in the comments on my post on reddit. Shoutout to /r/rails!
