Rails: Postgres Partial Indexing
Postgres has a nice feature where you can index only the values you want to query on. Today I learned that Rails has a nice shortcut for taking advantage of said feature.

Anti-Decay Programming
de•cay noun - the state or process of rotting or decomposition. Let us kick off the new year with a lovely post on decay. All systems decay. Even when you continually work on improving the system, it decays. That said, in my experience, not all decay is equal with
