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.

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...

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.

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

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.

Comprar "acciones Trump" no creo que les vaya a salir a cuenta. Todo es jauja, hasta que Trump empiece a hostigar a Europa, lo que pasará más pronto que tarde.

Los conservadores canadienses ya lo han aprendido a las malas: su distancia con los liberales se ha reducido en más de 10 puntos.
