Hey -- there's a Chime listing on my exact team. This is a remote job for US/Canada applicants.

careers.chime.com/en/jobs/8414...

It's doing a lot of the work I do on our Ruby code, but focused on our Python teams.

Happy to answer questions about this here or via DM.

I have to admit that I'm wildly curious what you would make of Glasshouse in 2026. 2006 me liked it quite a lot, but I have no idea how it would read now.

The 2025 Book Post – Noel Rappin Writes Here I just write here

It's time for the somewhat-awaited annual book post, a tradition unlike any other...

noelrappin.com/blog/2026/03...

It's kinda long this year, but I really did extra-love my top two books of the year, so maybe at least scroll to the end?

I've been saying forever that Concrete would make an amazing TV series.

While we wait for that, you should check out the original stories.

When I first saw the title One Battle After Another, it played in my head to this tune. That hasn’t stopped. (I’m not well.)

What I want to do is build out my own kind of specific CLI tool (kind of like Claude Code, user enters commands, main section shows results). I've been going back and forth on what tooling works, Phlex-ish sounds good to me

Programming Ruby 4 (6th edition) Code Ruby, Be Happy!

I haven't mentioned it yet here, but Programming Ruby 4.0 does have a new beta out that runs all code against Ruby 4.0.0 final, and also covers Minitest 6.0 and a couple of other late breaking changes:

This Dave Berg strip is from MAD Magazine issue 316. In the strip, Nick Meglin and John Ficarra are talking to Charlie Kadau. Nick say "Charlie, the reason we didn't give you a promotion is because you're so indecisive." John adds "Do you disagree?" Charlie responds "Well, yes and no..."

In the background, other staffers (and I) watch the discussion. We really ought to mind our own business. Bill Gaines -- who recently passed away -- appears in a picture hanging on the wall. I think this may have been the first time he appeared as portrait in a Lighter Side strip.

Also, in news that will intrigue at least one or two of you, I actually managed to do mini book reviews as I read books in 2025, meaning my 2025 "Books I Liked" post, which traditionally comes out in, like, April, may actually come out in January.

The next beta of the book, which runs all code under Ruby 4.0 will come out this week. We'll have another one or two later this month with cleanup and any very late-breaking changes.
