Building a GraphQL API in Rails - Part 1

This is a series blog post cover above three topics of GraphQL:

1. About GraphQL
2. Building a basic API with Rails
3. Some best practices

GraphQL is not a new thing, it already exist for a while, the reason I decide to investigate it is because Github released their GraphQL API alpha currently. We know Github has been a very good company for a long time, their RESTful API also becomes some kind of standard for developers, so it's pretty interesting to see what’s new they've been released.

Finding a Ruby memory leak using a time analysis

When developing a program in Ruby, you may sometimes encounter a memory leak. For a while now, Ruby has a facility to gather information about what objects are laying around: ObjectSpace.

There are several approaches one can take to debug a leak. This discusses a time-based approach, where a full memory dump is generated every, say, 5 minutes, during a time that the memory leak is showing up.
