Thoughts on open source software, the Internet, Ruby, Golang and programming in general.

Ruby 2.3 was released last month with yet another bunch of performance improvements. But is it really faster than 2.2? Let's take a look.

One of the highly anticipated feature of Rails 5 is the official solution for integrating web socket communication with Rails, dubbed Action Cable.

Rails 5 provides cache_key for ActiveRecord::Relation that can help in caching result of a collection of records.

Document-Stores, Key-Stores, and Relational databases all have different use cases that they work best for, but there is quite a bit of overlap. What if we were to have the advantages of all of these databases in one hybrid database?

It happened gradually so you may have missed it, but Twitter has grown up. It started as a struggling three-tierish Ruby on Rails website to become a beautifully service driven core that we actually go to now to see if other services are down. Quite a change.

The idea is that if code can be changed and your tests do not notice, either that code isn't being covered or it does not have a speced side effect.
