Emaigos imports Google contacts and calendars into Emacs. Contacts are stored in a Big Brother Database (BBDB) file, which makes them usable with many Emacs email packages, like Gnus. Google calendars are stored as a single Org-mode file, so events may be viewed as a structured document and possibly shown within an Agenda view. With Emaigos, it's possible to use Google as a contacts and calendars manager, while having all the same data available within Emacs. The original Google contacts and calendars are not modified in any way by Emaigos. The name "Emaigos" is an acronym for "EMAcs Importer for GOogle Stuff".
PyParticles is a particle simulation toolbox entirely written in Python. It simulates a particle-by-particle model with the most popular integrations methods, including Euler, Runge Kutta, and Midpoint. It represents the results on an OpenGL or Matplotlib plot, and offers an easy-to-use API.
schwinn810 allows you to extract data (tracks, laps, points, and waypoints) from a Schwinn 810 GPS sport watch with a heart rate monitor. It can optionally feed points to gpsbabel to convert data into other formats like TCX, GPX, and KML. A standalone converter for TCX with split-lap and heart rate data is provided. It should work on any platform as long as there is a driver for the CP2102 USB-UART bridge from SiLabs and python-serial.
