Just checked the "Best Sellers in Ruby Programming"(lnkd.in/gq4sKWkt) on Amazon and found a pleasant surprise!

After 3 years of work, my book Rails Scales! is finally complete, and the print copies are now available! I recorded a short unboxing video of my copies to share with you. You can get your own paperback copy of Rails Scales! on Amazon: www.amazon.com/Rails-Scales...

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. #ruby #rails www.youtube.com/watch?v=0cI8...

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.

Hard week. In the world, and at work. This too shall pass.

New Year, new Ruby talks proposals... It's been a productive day, I already got 4 ready, haha.

This is so spot on. Two things: 1. Being focused on producing output the fastest way possible means that you will never prioritize "going deep" 2. Going deep (and down the rabbit hole) is how you learn more: but you need to balance it. Figure out how to do both: it's tricky!

The Last Jedi is the 3rd best Star Wars movie. There, I said it.

Updating my book to Rails 8 (it was written with an example application written in 7) I found an unexpected difference. In Rails 8, the request logs do not show the amount of memory allocations. This was quite useful for the examples of the book. Any way to turn this back on?

here's a computer take: it didn't actually take that much computing power to go to the moon

There's this evergreen joke on software development that goes something like this: "We're done with 90% of the project. Which means we only have the other 90% left to go." It's funny because it's true. It's also why experienced engineers are in-demand: they are the "finishers." AI tools: not now.

My book "Rails Scales!" is currently discounted. The book is still on beta, but the manuscript is completed. You don't have much longer to get the beta!

Just finished writing my first book, Rails Scales! (pragprog.com/titles/cprpo...) Here is how it ends: "Scalability is also empowering humans to reach their full potential for creativity and innovation. Here's to the Ruby community, and to all the other fools who dream. Here's to the mess we make!"

Posts like this make me realize how opinions in software architecture field have changed in the last years. From a software engineer at AirBnB: "a polished monolith would have served us far better than our sprawling service ecosystem. [...]Microservices made our system more complex and brittle."
