Given an observed image containing a chessboard or a grid of circles, mrgingham locates the board in the image, and precisely computes the location of the chessboard corners (or circle centers). This is similar to the routines in OpenCV, but is faster and more robust.

Implements a procedure for forecasting time series data based on an additive model where non-linear trends are fit with yearly, weekly, and daily seasonality, plus holiday effects. It works best with time series that have strong seasonal effects and several seasons of historical data. Prophet is robust to missing data and shifts in the trend, and typically handles outliers well.

libuEv is a small event loop that wraps the Linux epoll() family of APIs. It is similar to the more established libevent, libev and the venerable Xt(3) event loop. The u (micro) in the name refers to both its limited feature set and the small size impact of the library.

Clang-format is both a library and a stand-alone tool with the goal of automatically reformatting C++ sources files according to configurable style guides. To do so, clang-format uses Clang's Lexer to transform an input file into a token stream and then changes all the whitespace around those tokens. The goal is for clang-format to both serve both as a user tool (ideally with powerful IDE integrations) and part of other refactoring tools, e.g. to do a reformatting of all the lines changed during a renaming.
