Post-recording update: As I've been lobbying for (both publicly and behind the scenes), it has been announced that the RubyGems and Bundler client libraries are being transferred to Matz and the Ruby core team.

Mike McQuaid (of Homebrew fame) and I scheduled this episode of Hot Fix a week before the Ruby community exploded. Hot Fix is all about getting spicy, but even we were a little wary of the heat in that particular kitchen. The problem Mike brought to the table is the same one he's always on about: open source is not a career. Incidentally, Mike's favorite topic also happens to be relevant to the latest RubyGems controversy—because it all boils down to paying people to work on open source.

Not content to miss out on the fun, Jerod from The Changelog asked if he could join and discuss the ongoing Ruby drama as a group. So we decided to team up and do a collab episode—call it Breaking Changelog, I guess? It's nothing if not efficient: record once, edit twice, and syndicate everywhere.

If you don't mind swear words, listen to this version. If you don't like swearing, what the fuck are you doing here? (But seriously, you can listen to their edit if you want!)

If you know who José Valim is, then you know he probably made a mistake by joining me for our third installment of 🔥Hotfix🔥. The inventor of the Elixir programming language is at it again with his colleagues at Dashbit and they've got a new product called Tidewave. It's a coding agent with a twist: it has such a deep level of integration with your web framework that it can get the executable feedback it needs to tackle the entire feature development lifecycle.

I do eventually let him plug the tool (and our conversation genuinely makes me want to try it—I logged a todo and everything!), but to be on Hotfix you gotta bring a thorny problem to the table, and he picked a great one: marketing hype aside, nobody has a clue what the future of AI agents looks like.

Like always, we totally 100% and A+ solved the problem by correctly predicting the future. You gotta listen to find out.

Every time I talk to José, I get ideas for what I should be doing instead of what I'm actually doing. If you feel so inspired, write into [email protected] and I'll read it on the next mainline version release of Breaking Change.

You can follow José on Bsky, X, and Mastodon. Pick your poison. ☠️

Hey, look! Breaking Change now has chapter support for each segment! More on how I did that while still upholding my commitment to laziness later.

I didn't get a good job connecting this version's release to what I was referencing, so to be clear I was referring to my heart rate as opposed to any other bodily functions. The other ones are getting up just fine, thank you. Get your head out of the gutter.

Thanks for all the great e-mails the last couple weeks! Throw yours on the pile at [email protected]. Hopefully Fastmail won't lose it.

It's an emergency bonus edition of Breaking Change as I take the covers off yet another show-within-a-show. I call it Feature Release, and its job is to fill in that middle number in our semantically versioned series of conversations together. No pun, no news, just some timely content wrapped up in a name, logo, and jingle package that still has that new podcast smell.

It's a 1-hour review of the Airpods, Apple Watch, and iPhone updates Apple announced today. You can see the full event video on YouTube. The Verge has a 17 minute abridged version if you just want the synopsis.

Please enjoy this episode of Feature Release! It may be the only one. Write into [email protected] with your feedback!

Remember it is your civic duty to e-mail me at [email protected]. As of this episode, that address is monitored by Fastmail, so there's a higher probability I'll actually get your e-mail!

🔥Hotfix🔥 is back with a new guest! Scott Werner is the CEO of Sublayer, helps organize the Artificial Ruby meetup in NYC, and is the author of the extremely well-named (and well-written) Substack, Works on my Machine.

In this conversation, we jointly grapple with WTF is happening to programming as a career. Did the unprecedented peacetime the software industry experienced from 2005-2022 make us all soft? Is the era of code-writing agents fundamentally changing the nature of the job? Should we be less like DHH/Matz and more like why the lucky stiff?

We'd love to get your feedback to [email protected] — I'll read it all and flag relevant questions and comments for the next Breaking Change.

A handful of things we mentioned:

Thanks for writing so many lovely emails to [email protected]. Hell, thanks even for the unlovely ones.

Be sure to look out for me showing up on Dead Code at some point after it records next Tuesday. I'm realizing not all podcasts have a 1-hour-or-less turnaround time like this one does.

As promised, some URLs follow:

I've made it! I'm over the hump! I'm actually writing* my language-learning app in Swift!

Send an email expressing how proud you are of me to [email protected]. Or if there's any news worth following that isn't about AI. Too much AI stuff lately.

*And by "I'm writing", I admit Claude Code is doing a lot of the heavy lifting here.

Finally, a recommendation-heavy, full-mailbag show. Been a while.

Welcome to the first episode of 🔥Hotfix🔥! Breaking Change's first show-within-a-show, wherein I let somebody else talk for once. Each episode will show up as a patch release in the Breaking Change feed and feature guests with Hot takes about a relevant issue and a clear fix in mind for what we can do about it.

That first guest is a long-time collaborator and top 5 all-time colleague of mine named Dave Mosher, who's here to drop some truth bombs labeled "agentic coding" on the unsuspecting populace.

My secret mission on each of these is to lean into the show's E-for-explicit tag and try to get the guest to say something that could get them fired. I failed this time, but in fairness to me, Dave is Canadian.

We'd love to get your feedback to [email protected] — I'll read it all and flag relevant questions and comments for the next Breaking Change.
