Having met with both sides on the current RubyCentral/RubyGems situation, here's my take: - RubyCentral have managed this exceptionally poorly in many ways including removing literally the most active member of the RubyGems organisation by mistake who has declined to return

Bending Ruby to make the code more readable can sometimes feel like a gimmick. But I think it's super important. Understanding what the code is doing was always important, but even more so with LLMs. Which is why I really like the direction rubyllm.com is taking: readability first.

All of the #RailsWorld videos are now edited and live and my presentation is here: www.youtube.com/watch?v=kWFY... :)

Almost every single experienced developer I worked with loves removing code. It's not some kind of weird developer fetish. All things equal, a solution with less code is usually easer to: understand, maintain AND extend. In other words: it's more valuable to the business.

Here's Rails World 2025 from a first time speaker perspective: radanskoric.com/news/rails-w...

RailsWorld in Amsterdam was intense but also very rewarding. Met old friends, new friends, online friends. I'm writing up a blog post to sum it all up, but for now, here's a photo of the most intense, stresful moment: hooked up to mic, people coming in, waiting for the start ...

I saw a bus on the highway. It was in wild colours and had a large sign: "Party bus for 18 to 39yo". I was relieved that I'm 40 and society allows me to just read a book in the shade, but that was a close call!

If you were still on asdf 0.15 and were not particularly attached to it. What would you move to: asdf 0.16 or mise? Asking for myself. :)

Just republished a classic article! 👇🏾 Have a great idea? Prove it by finding ten customers ready to hand over cash. Everything else is avoiding the truth. Many thanks for spreading the love with ❤️ and 🔁!

I'm working on the web version of masterhotwire.com and I like how meta it is. It's a version of the book built using the technology from the book and I'm using this unfinished version to look up things I forgot while I'm working on finishing it.

Always forgetting to add an alt-text to your images on Bluesky? Me too! Go to settings > accessibility > and click “Require alt-text before posting”. Then you’ll never forget again. Alt-texts are important to people with visual impairments. Just a small alt-text makes your post more inclusive.

This seals the deal for me, I need to switch away from Windsurf, I expect it to go downhill from this: techcrunch.com/2025/08/05/t... Cursor is the easy switch, but Zed is interesting, especially since it got debugger support recently. Advice? Anyone got Ruby debugger running with Zed?

Digging into exactly how Hotwire Native integrates with Turbo Drive to be able to convert web app page navigation into native looking screens navigation: radanskoric.com/articles/tur...

Really nice to see a new library of frontend components based on Stimulus. And it's looking very polished: railsblocks.com

Ok, I'll be honest. I was a bit skeptical about the value of the addition of "it" as an implicit keyword for the block parameter. Until now. Now I'm sold on it. :) #ruby

I've added an all new section on Hotwire Native to "Master Hotwire". I've put over 70h into making it the fastest way for experienced Rails developers to get up to speed with Hotwire Native. But I'll leave the old price until the end of the week: masterhotwire.com

I'm trying to shape a thought on LLMs, wondering what others think. Here's what I got: "Understanding" was always more valuable than just "knowing". And LLMs give "knowledge" for free but don't "understand". This must skyrocket the value of "understanding". So this is where human effort should go.

Next Tuesday I'll add a whole new Hotwire Native section to masterhotwire.com. It's a deep but concise intro written specifically for experienced Rails developers. I'll up the price a few days later. Also, a discount will go out to my mailing list on Tuesday. #hotwire

Finished going over all 170 comments from beta readers of second part of "Master Hotwire". I'm so much happier with it now! Getting other people to critique your work is always sooo useful, from code review to beta reader feedback.

People outside tech starting to realize how quality software and typing/generating code fast are not correlated

If you can read mathematical notation, it's usually the shortest way to express a mathematical concept. Certainly shorter than English. Every time I see an AI prompt be much shorter than the code it makes me wonder what we're doing wrong that the code can't be more expressive?!?

Does anyone know why pretty much all LLMs like to use em dashes so much? They'll eager-use them near-everywhere. It's weird. Where in the training data could it be coming from?

Turns out, creating a simple AI coding agent is not very hard, especially in Ruby: radanskoric.com/articles/cod...

Multitasking was always a bad idea. At best humans are faking it, or, in the case of me personally, failing miserably. And in the age of AI it's full expiry date is around the corner: anything simple enough that humans can multitask it will soon be automated. Best to focus on the deep, human work.

Episode 56 crossed the finish line! 🏃‍♂️ Jess & Jeremy chat with Radan Skorić about discovering Rails, technical blogging, and writing his forthcoming book, Master Hotwire. Thanks again for the great conversation, Radan! 🙏 www.indierails.com/56

I've stumbled upon the concept of "Server Driven UI" in mobile app development. I don't understand how is this not reinventing the web? Wouldn't this direction eventually converge on something like #hotwirenative, just taking much longer to get there?

As announced at RubyKaigi today, I've been working on a new HTML-Aware ERB Parser that I just released today. Introducing Herb — a fast, modern, and HTML-aware ERB parser, designed from the ground up for smarter developer tooling. #rubykaigi #rubykaigi2025

Just scheduled the next RubyZG Meetup: Tuesday, April 29th at Kodius. We've got some very nice talks lined up about Ruby's Global VM Lock and about Ruby's async programming capabilities: www.meetup.com/rubyzg/event...

If you want to use an npm package that you can’t just pin to the importmap but that needs bundling, do you need to abandon the default Rails asset pipeline? Absolutely not, here’s how you can bundle just one package and keep the rest on vanilla Rails asset pipeline: radanskoric.com/articles/rai...

Coding at its best is not just getting something to work. It's modelling the problem domain in a way that captures all the important and simplifies the unimportant parts. Done well, the pure act of modelling, with code as just a tool creates huge value. And then vibe coding side steps all of that.

This was a fun episode to record. I already got my copy of "Master Hotwire"! Take a listen to the episode and grab yours with a special discount for listeners 😉

Big thanks to @drbragg.dev for hosting me on "Code and the coding coders who code it" and especially thank you for publishing on April 1st. It makes me childishly happy that someone might wonder if the episode is an April Fools joke :) www.buzzsprout.com/1927628/epis...

Enjoyable little coding challenge from @cassidoo.co this week. Solved in Ruby (using Rails's Active Support for time munging) The problem: buttondown.com/cassidoo/ar...

I've been digging into the default Rails 8 asset pipeline, doing some a bit unusual things. Here's how to combine Importmaps to be able to use different maps on different parts of the website: radanskoric.com/articles/rai...

This is inaccurate. There is no known vulnerability with Signal's core tech. The memo was discussing phishing attempts, which Signal has worked to mitigate. And it was hastily reported. It's important not to spread misinfo that can confuse people into moving away from meaningfully private comms.

The older I get the more I'm convinced that number one single factor for easier software maintenance is: good names! Is that controversial? Code is communication about how systems work. Verbs and nouns are key tools of human communication. They've evolved for longer than any other programming tool.

How appropriate "vibe coding" is will depend a lot on project's risk tolerance. Yes, I'll happily play a vibe coded game. I would not come anywhere near an elevator with vibe coded control software. There's a spectrum in between but for me the border is pretty close to the game end. What about you?

Happy Pi day. :)

I'm so excited to share the tool I've been working on for the past month! Do you know how much it would cost to host YOUR app across Heroku, Render, Fly, and Railway? Now you can compare costs side-by-side. judoscale.com/tools/paas-...

I wanted to customize Rails 8 default asset setup and I couldn't find documentation or articles explaining clearly how Propshaft and importmap-rails interact so I ended up writing it: radanskoric.com/articles/rai... #rubyonrails

I love it when Ruby makes me smile with its elegance. Need to find next few months that start on a Monday? No problem. (P.S. yes, there's some ActiveSupport in there) #ruby #rubyonrails
