Some indie bookstores also carry the book! I think the recommended way to buy it outside of the US is using Biblio: biblio.es/libro/rails-...

I also asked my editor, maybe there are more options.

It's finally out! My talk "Full Circle: How Modern Ruby Powers the Re-integration of High-Speed Microservices into Rails".

Recommended if you are into Ruby, architectural debates with some historical perspective, and mostly Twin Peaks.

In Barcelona, terraces were *super* full. We were lucky this happened in April, on such a nice sunny day.

On the other hand, supermarket shelves were emptied quite fast. In my Mercadona last afternoon there was no bread, no conserves, no water. People went "Walking Dead" mode pretty fast...

My book, “Rails Scales!” is already available for presale at Barnes & Noble. 😍

Rails Scales!: Practical Techniques for Performance and Growth|Paperback

Rails doesn't scale. So say the naysayers. They’re wrong. Ruby on Rails runs some of the biggest sites in the world, impacting the lives of millions of users while efficiently crunching petabyte...

In the book there is another chapter about Product Design, and how communication between product and engineering is paramount to build a viable planetary-scale product. I think most experienced engineer have seen how apparently minor product features have *massive* engineering consequences.

It's its own thing. The book is mainly about improving performance, but there is a whole chapter dedicated to "Scaling, beyond performance". It talks mainly about eng org issues.

Cristian Planas @cplanas.bsky.social · Feb 26

Yep! The book is completed. We hope to bring it to printing very soon!

I’ll make sure to send you a copy as soon as I have the book!

Completely understandable. I do quite a few interviews, and AI made it very challenging.

Before, when a candidate was copying, it was kind of easy to spot: he didn't understand the algo. Now, with LLMs, he will give you the best step-by-step explanation of the algo you have ever heard.

Just released a new version of Rails Scales! (pragprog.com/titles/cprpo...). This one includes the completed book. :)

I'm currently working on the last revision, which updates the book from Rails 7 to 8. Mostly minor changes, with the exception that now I will cover Solid Queue.
