This script looks for text files in a specific folder that include completed tasks ('@done') and timestamps, and then collects them into a daily log for the Day One journaling application. It works especially well when it's connected to IFTTT. See more details at http://craigeley.com/tagged/sifttter

# SIFTTTER 1.5: An IFTTT-to-Day One Logger by Craig Eley 2014 <http://craigeley.com>
# Based on tp-dailylog.rb by Brett Terpstra 2012 <http://brettterpstra.com>
# Multiple Date Function by Paul Hayes 2014 <http://paulrhayes.com>
#
# Notes:
# * Uses `mdfind` to locate a specific folder of IFTTT-generated text files changed in the last day
# * The location of your folder should be hardcoded in line 67, and the location of your Day One in line 66
# * Scans leading timestamps in each line matching the selected dates
# * Does not alter text files in any way

The only simple way to do SSH in Python today is to use subprocess + OpenSSH...
#!/usr/bin/python
# All SSH libraries for Python are junk (2011-10-13).
# Too low-level (libssh2), too buggy (paramiko), too complicated
# (both), too poor in features (no use of the agent, for instance)
# Here is the right solution today:
import subprocess
import sys
