Automatically fetch remotes then fast forward to the new changes or launch a GUI.
# first update all remote branches
git fetch --all --prune
# loop over all local/remote pairs
git for-each-ref --format="%(refname:short) %(upstream:short)" refs/heads | \
while read local remote
do
# make sure remote exists
[ -z "$remote" ] && continue

A simple bookmarklet to add an alert feature to bitcoinwisdom.com :)
interval_id = high = low = null
ticker = $ '#price'
alert_url = 'http://www.angelfire.com/ut/jlpicard/images/picalert.wav'
start = ->
do nodes.stop.show
do nodes.start.hide
interval_id = setInterval ->
current_price = parseFloat do ticker.text
unless high > current_price > low

Getting started with testing in Python

Why Test

  • Tells you when your code is broken
  • Manual testing sucks
  • Prevent against regressions
    • Upgrading dependencies
    • Refactoring
  • Documentation
    • Other devs can read your tests to see how you intended your code to be used
