Here’s the setup: You are a web server named Puma. You need to accept incoming connections and give them to your thread pool, but
Do you have 5 minutes? Do you want to decrease the “over the wire” size of your Rails app by 80%? Sure you do! I added Rack::Deflate to CodeTriage.com, the best way to get started in Open Source, and went from a page size of 85,523 bytes to 15,568 bytes (over the wire). You can verify with this retro looking web based compression tool. First up, what does Rack Deflate do and why do we want to use

WEBrick is the “slowest” webserver in Ruby, how could it possibly be webscale? To answer this question and explore Is Ruby Too Slow For Web-Scale?, we will compare WEBrick to a real piece of “webscale” tech: NGINX. While there might be some faster webservers on the market, is there a case where WEBrick is fast enough? Before we can dig into that question, let’s look at a real world deployment of W

Database load can be a silent performance killer. I’ve been optimizing the query performance of a web app I run designed to get p
How does an asset get compiled? It’s less of a pipeline and more of a recursive ball of, well assets. To understand the process we will, start off with an asset with no directives (no require at the top). We’ll then walk through all the steps Sprockets goes through until a usable asset is loaded into memory. For this example we will use a js.erb file to see how a “complex” file (i.e. multiple exte
It’s impossible to just glance at something and know how things are interacting. You change this one method that you thought was only being used in this one part of the project, and something else breaks. For more information about how Sprockets work, I highly recommend you go to Rafael’s talk What is the solution to god objects? We can move logic over to helper classes. For example I introduced t
This weekend I made my OVER 9000 pull request to Rails, that features a demo of the functionality in GIF format. I’ve had a number of people ask the same question “what is your GIF workflow?”. For the detail oriented of you in the crowd, here it is. The Content I filmed my screen using Screen Flow, which I used to do all my work on UT on Rails, it’s not free at $99, but does editing, exporting, an
