If you update or delete often rows watching bloat tables and indexes is important. This article is a great explanation and I also recommend using the gem rails-pg-extras to watch bloat ratios: github.com/pawurb/rails...

One thing I'm really excited about in Ruby 4.0 is that object allocation is going to get a nice speed boost

Tonight I will be presenting at Geneva.rb on how to protect a web application against bots and brute force attacks without annoying humans and **without relying on a third-party service**.

Next Wednesday I will give a presentation at Zurich.rb, and then on the 19th November at Geneva.rb: How to protect web applications against spam bots and brute force attacks without annoying humans, and why I think captchas are not the best solution.

AI can write tests, but it doesn't understand what truly matters to you, your product, or your codebase. Without guidance, it follows patterns, and the output feels sometimes good, sometimes bad. That's why I'm launching a new workshop: Reliable Test Case Generation with AI.

If your are unsure about adding a new column to a table or creating a new model, always create a model. Your code base will thank you. Let's have a look to the User model.

TIL: In SQL the RETURNING instruction accepts any expression, not only a column name. That seems so obvious, but I took all that time to notice it 😅

6 spots filled, 9 remaining for the Good Enough Workshop this Friday at 15:00 UTC Here are all the details about the workshop. In case you have questions reply here or via email -> [email protected]

I tried to explain why I don't believe the recent accusations toward my former teammates, as well as how the Ruby and Rails Infra team at Shopify operates and why it can be trusted. byroot.github.io/opensource/r...

I am very happy to have become dual citizen 💎 since last @euruko.org. Thanks @adrianthedev.com and @avohq.io 😀

Switched to ReActionView in production! Deploy on Friday and go away 🙃

So using Ruby, what is the largest Fibonacci number we can calculate quickly? This article is a deep dive into the world of Fibonacci numbers to show some really neat tools that Ruby provides. www.rorvswild.com/blog/2025/fi...

Developers who remove lines of code are the ones who maintain a project's productivity. Those who frantically add lines of code sabotage it.

“If this test fails, would I care or just ignore it?” “If this works, what does it prove?” “If this fails, do I know why?” If a test doesn’t help you think better, it’s noise. More on this mindset → Aug 1 workshop goodenoughtesting.com

I just published a recap of my RailsConf 2025 talk on my blog! Herb v0.4.0 is out, now with the Herb Linter, a Formatter preview, and deeper editor integration for HTML+ERB. Plus: a look at ReActionView, my vision for the future of the Rails view layer. #railsconf #railsconf2025 @rubycentral.org

I knew that handling time in programming is hard, but not that hard: shanrauf.com/archive/how-....

Do yourself a favor and buy a programming book in addition to your AI subscription. One is consumption, the other is investment in yourself. You will get more skilled at the end.

Internet must remain decentralized. Cloudflare is the easy choice to protect your website, but it has a hidden cost. It controls which trafic goes to your website and can read it. This price is too high for me, and for you too. torrentfreak.com/cloudflare-c...

I released version 0.4.0 of active_hashcash. Thanks to @ivanverges.bsky.social and @elalemanyo.bsky.social for their contributions. ActiveHashcash protects Rails applications against bots and brute force attacks without annoying humans. github.com/BaseSecrete/...

Namespaces 101 During the last days I have done an immersion into namespaces, the new big feature that is coming in Ruby. Here's a digested mental model for you all. gist.github.com/fxn/86ad8584...

Among things to do at least once in your life, there is attending Friendly.rb. The conf and the organizers are great!

Got attacked by a botnet with more than 18000 IPs. ActiveHashcash saved that Rails app. I strongly believe that is the best protection since CPU is the most expensive in hardware and it does not annoy final users.

Do you remember the song Ruby Ruby Ruby Ruby (www.youtube.com/watch?v=qObz...) ? There is one version which has been recorded during a Ruby conference by Ruby developers a long time ago. I think it was in Poland. Could you help me find it?
