Building a JSON API with Rails 5
Rails is great for making traditional server-rendered web applications. It has support for cookies, sessions, and other browser-specific functionality right out of the box. It's also great for building JSON APIs, but why include a whole bunch of functionality that we aren't going to use if what we want is to simply build a JSON API?

Debugging memory leaks in Ruby

Nobody understands the GIL
Nobody understands the GIL Published on June 12, 2013 by Jesse Storimer Throughout most of my time in the Ruby community, MRI's infamous GIL has been an elusive creature for me.
