Vendo virado

Em uma caluladora de bolso os dígitos são representados por pequenas barras no visor de cristal líquido:

Quando olhamos com o visor de cabeça para baixo alguns números ainda podem ser lidos (só que com outros valores). Por exemplo, 1995 vira 5661. O quinto número que pode ser lido de cabeça para baixo é 8, e o décimo-quinto é 21, que passa a valer 12 quando é visto de cabeça para baixo.

  # monkey patching Ember.TextField so that you can add delay=500 to make the
  # TextField to update the binding value in debounced manner with delay of 500ms.
  # That is it will only update the value if there is a unsubmitted change and 
  # no user input for the specified delay period.
  # While no delay spcified, it's just the plain Ember.TextField
  # usage in handlebars:
  # {{view Ember.TextField valueBinding="someValue" delay=500}}
  Ember.TextField.reopen {
    delay: null # delayed period for updating the binding value in ms
    _debouncedSet: (key,value,delay)->Ember.run.debounce(this, Ember.set, this, key, value, delay)

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

# Prints a basic gemspec for GEMNAME based on your git-config info.
# If -s is passed, saves it as a GEMNAME.gemspec in the current

# Once you check this gemspec into your project, releasing a new gem
