Hello Rubyists! Today, I’m launching a new product: The Ruby on Rails Performance Apocrypha. Over the last four years, I’ve written a lot of stuff to this newsletter. Until now, none of that stuff has been publicly accessible if you wanted to go back and read it again. If something useful was posted to the newsletter before you subscribed, you were just sort of screwed. So, I’ve compiled 4 years of writing to this newsletter into a book. It covers my usual topics: performance science an...| Speedshop - Ruby on Rails performance consulting

I’ve noticed four different factors that prevent software organizations from improving the performance of their Rails applications, and I’d...| Speedshop - Ruby on Rails performance consulting
Today, the Complete Guide to Rails Performance has been updated to version 2.0. You can purchase it here. All existing purchasers have had their copies updated on Gumroad. When I started this project, I always believed that a digital course should be better than a typical paperback programming book. That’s why I don’t include any DRM or proprietary video codecs. That’s why I think, like most software, updates should be free. “Version 2.0” isn’t quite as drastic a change as a softw...| Speedshop - Ruby on Rails performance consulting
