Caching with NSCache, or, The most underrated Objective-C Class
“There are only two hard things in Computer Science: cache invalidation and naming things.” —Phil Karlton There are four things you need to know about NSCache.

It’s programming from here on out
There comes that point in every project where the “hard” part has been solved. Where the learning curve has been topped and one can start getting into the flow. The hacker equivalent to “smooth sailing from here on out”: “It’s programming from here on out.” Happy hacking.

Today I’ve been playing around with sqlAlchemy and Elixir. I was having problems with how some strings (Chinese Characters) were being encoded and stored. The issue was with the metadata.bind statement (create_engine() without Elixir) before it was: metadata.bind = ‘mysql://username:password@localhost/database’ You need to select utf8 encoding manually. metadata.bind = ‘mysql://username:password@localhost/database?charset=utf8′ or, plain SQLAlchemy: db = [...]
