Are we going to generally see less interest in learning new programming languages? Even less motivation for creating new ones?

I think autoload_relative is a big deal, not for Zeitwerk (Zeitwerk already uses absolute paths exclusively), but for Ruby. My personal hunch is that $LOAD_PATH lookups should be eliminated, and Kernel#require deemphasized. Let me elaborate.

Just landed in Ruby master: Dir.scan: List directories with entry types using half the syscalls (mod :unknown), by @byroot.bsky.social: github.com/ruby/ruby/co... autoload_relative: Like require_relative, but for autoloads, by @ioquatix.bsky.social: github.com/ruby/ruby/pu...

When thinking about the new **experimental** Ruby::Box, you cannot have a fork mental model. A box is a blank slate that inherits nothing from who created it. You start from scratch, no gems loaded (conceptually), no monkey patches in place, etc.

Cool one. I have always said: Your monolith is not such, you already have a SOA. You did no write Redis, Sidekiq, or the error tracker, but SOA is about splits, responsibilities, communicarion, etc. If the service was developed in-house or not does not matter. www.iankduncan.com/engineering/...

In agent-based development Waterfall meets Agile.

Something that is proving great for my supervised/interactive agent-based work is to provide the source code of the relevant dependencies. Like, the source code of Active Record is here, and of this related gem is here (bundle show), ..., please study them in depth. Then, we plan.

unusual job perks: getting to watch @evanphx.dev argue with a robot about kernel memory semantics 🤣🍿

At the same time, we should be cautious about extrapolating from the previous world. When the printing press was invented, people worried that memory skills would deteriorate, as oral transmission faded And here we are, in a different world. (BTW, did those people ever play the telephone game?)

As most people, I am figuring AI out. Not AI per se, but my related personal feelings. You won't grow as before. Can a junior develop seniority to review AI generated solutions? Maybe? To be seen. The builders are in a paradise, the thinkers... not as much fun. www.jernesto.com/articles/thi...

I guess my Stevens from 2001 could be updated 😅.

@eregon.me @byroot.bsky.social I am writing that extended directory listing in C in Zeitwerk itself, with fallback to stat functions if needed, and to Ruby as last resort. By being internal it can ad-hoc, like, filter hidden files out, and only return :file, :directory, or nil. That is all I need.

While doing my cardio I was like, OMG, who is this? How much does it take to be able to solo on tenor like that?! At the end of the piece, conductor says: "Ladies and gentlemen: Michael Brecker". So, it just takes a lifetime plus being among the best of all time. open.spotify.com/track/1DmLu6...

I have it, but I might discard it. The new behavior creates the dummy modules at scan time, descends to set autoloads, and recurses. Traversal stops at .rb files. I have checked booting a huge Rails app: from 8K autoloads set we go now up to 30K, which increases boot time in dev/test by 10%.

To me, the concept "vibe coding" suggests superficial involvement and lack of agency. If you used AI to help in a process that *you own* (generating, understanding, whatever), that is different. That is not vibe coding, it is you producing the same patch with new tools.

I have started "Infinite Jest". Let's compare forearm circumference before/after.

I am working these days on a change to Zeitwerk that will remove a hack. When I wrote the gem, autoloading had been brittle for more than a decade and I wanted to mimic the classic autoloader as much as possible for users' peace of mind. But there was a corner case that had no clean solution.

If you keep working on something, turns out eventually you may finish it. So it is with "Master Hotwire" book! I've finally finished it and it's available in Web, PDF and EPUB formats at masterhotwire.com I started working on it a bit under 2 years ago. :)

someone built a Linux CPU scheduler that makes scheduling decisions based on planetary positions and zodiac signs it actually works haha:

Tonight's the night: Wagner's "Tristan und Isolde" at Gran Teatre del Liceu (the Opera House of Barcelona). So looking forward it, I have never seen this masterpiece live. Production is top, they perform at the Met in March.

Programming is 2/3 dealing with the non-happy path.

The SF Ruby workshops are out! 🌁🎉 In my workshop, we did an interactive dive into Rails' source, so you can find your way around the unstructured space that is most codebases. My style is impromptu and some attendees said it's not for everyone, but that's ok :)

This was an interesting read. I taught Perl at the University of Barcelona for 7 years, and in the exams my students had their editor of choice in computers connected to Internet, they could check docs, do web searches, etc. That is the real life I was preparing them for. ploum.net/2026-01-19-e...

There's this story about Paul Dirac in which he is in a conference or something, and someone approaches with small talk: "Lovely weather today!". He leaves the room, goes outside, checks, returns, and says "Yes". Well, I may have done something in that line 😂. True statements above all folks!

Wonder if code generation is going to be able to distinguish private APIs that have public visibility in langs that do not support lib or package levels. Because, up to now, the contract was: The public interface is in the docs, anything else is internal. @antirez what is your experience in C?

I don't have many opinions formed on the whole topic of AI just yet. But I believe writing detailed specs for code generation of non-trivial things, like writing good tests, need flight hours. Plus, you need flight hours for validation (at least for now, though some people directly push).

Before the internet, your references were local. Then, you could interact with world-class experts. In IRC, USENET, mailing lists, easy access to the best books, etc. I believe that exposure raised the level. Now, we are going to have an expert at our fingertips. The level is going to skyrocket.

I'd say I see Claude Code way more mentioned than Codex.

The constants API chapter in my book has RBS signatures. Annotations as docs are necessary and orthogonal to static vs dynamic typing. Readers have to know, e.g., constant names come as symbols. You can say that in English or using some standardized notation, but you have to say it.

Let me tell you a bit about the watch I got in Frankfurt. Sinn has its manufacture there, visiting their shop was obligatory 😀. Sinn specializes in what we call "tool watches". Timepieces engineered with a practical purpose. In the case of the U50 I got, diving and seawater are their thing.

Oh, you are the one who gets it. My model retirement house (since I first so it 25 years ago) is the museum-house of the poet Maximilian Voloshin in Crimea. Its biggest room is basically 2-stories high library (with ladders and all) with a panoramic window overlooking the sea 🥲

I would not retire to a beach, but to a library. Well, it could also be a library in the beach.

Happy New Year! 🎉 2025 was an incredible year for Ruby Events around the world and also for the @rubyevents.org platform! To celebrate, we're releasing RubyEvents Wrapped! A look back at talks, events, speakers, sponsors, and the Ruby community's year!

New year's getaway to Frankfurt. Night photo is the opera house, we are going to see Tosca tonight. Tried also some Sinn divers this morning in the old town boutique. Some are filled with oil and can go 5 km deep (not a typo!). But did not purchase any in the end.

That was an interesting read. That is why I want to self-publish, I want full control of the content and how to present it, among other things. My book is going to be rigurous and comprehensive you-are-here-for-the-real-deal. austinhenley.com/blog/cancele...

Given a class object `klass`, it is not uncommon to see klass.to_s to get its name. However, that is unnecessarily indirect. If you want the class name, just ask for it! klass.name That is more concise/intentional.

I used Turbo C quite a bit in the 90s. That color scheme with the blue background brings so many memories. youtu.be/xtKcagvogSA?...

Just published this year's version of my "Ruby Changes" project: a full annotated changelog for Ruby 4.0: rubyreferences.github.io/rubychanges/... Goals: Full, comprehensive, concise, well-structured. Examples, explanations of reasons, links to docs, all of it.

Will the future develop some sort of declarative language from which LLMs can produce implementations?

I’m very honored and grateful. Rails has given me a lot, and giving back through open source has always felt like the natural response. Looking forward to continuing the work. ❤️ I wrote a short note on my blog: marcoroth.dev/posts/rails-...

Yesterday was a nice and special day. Now enjoying Zurich by walk a bit before my flight.

We were very proud to present @marcoroth.dev with the Rails Luminary Award 2025. And yes, I was on a secret mission to Zurich 😀. rubyonrails.org/2025/12/17/m...

I'm really happy to see @marcoroth.dev receive the 2025 Rails Luminary Award! 🎉 He’s done so much for the Rails ecosystem and the Ruby community. Huge congrats, Marco! 🙌 And it's great to have @fxn.bsky.social and @amandabrooke.bsky.social around. #rails #RubyOnRails #ReActionView #herb
