Engineer & Rubyist.
Speaker of tech stuff with a dubious sense of humour (https://www.rubyvideo.dev/speakers/cristian-planas).
Author of Rails Scales! (https://t.co/g6sFeDDgp4).

I lived around: BCN, HEL, CPH, SF, NYC. Currently @zendesk.
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...

Now we had @cplanas.bsky.social do a **super fun** and inspiring talk about going full cycle from microservices to monolith. Really great!! 🔝🔝

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.

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.
