StevenMaude / password_animation.py
Last active August 24, 2016 22:33
Movie-like password cracking animation in Python that looks nifty. Code for guessing a string written for a problem in "Problem Solving with Algorithms and Data Structures" with my additional idea of printing every attempt and slowing down prints to make them readable. Tested with Python 2.7/3.4.

Use gpsbabel to convert Garmin .FIT to .gpx — requires a fairly recent version of gpsbabel (minimum 1.4.3); see https://www.stevenmaude.co.uk/posts/using-garmin-forerunner-watches-with-linux for more details on using Garmin watches with Linux
#!/bin/sh
# Usage: convert_gpx.sh <FIT filename>
# Should works whether you include the .FIT extension or not.
filename=$(basename "$1" .FIT)
gpsbabel -i garmin_fit -f "$filename".FIT -o gpx -F "$filename".gpx
