This week has been about a tool for rapid note management, a tool for shell history management, a streaming database for real-time applications, a hierarchical note taking application, trigonometry using turns instead of radians and a paper comparing state machine patterns.

# Turns are Better than Radians

An article looking into the common implementation of trigonometric functions in game engines and proposing an alternative using turns instead of radians.

# The Anthology of the Finite State Machine Design Patterns (pdf)

A paper comparing different finite state machine designs with focus on flexibility and associated costs.
