WatchWednesday for 20100929

It’s Wednesday again, time for us to serve up another quick list of projects to watch on GitHub. These are projects you might have missed or should could keep an eye on.

Heroku::Autoscale

David Dollar makes automatically scaling your Heroku dynos a snap with this gem. Simply add the gem to your Gemfile

gem 'heroku-autoscale'

and configure your Heroku credentials and the minimum and maximum numbers of dynos for your app in your rackup file

use Heroku::Autoscale,
  :username  => ENV["HEROKU_USERNAME"],
  :password  => ENV["HEROKU_PASSWORD"],
  :app_name  => ENV["HEROKU_APP_NAME"],
  :min_dynos => 2,
  :max_dynos => 5,
  :queue_wait_low  => 100,  # milliseconds
  :queue_wait_high => 5000, # milliseconds
  :min_frequency   => 10    # seconds

Now your app will scale up with traffic and down as traffic wanes.

Justin.tv’s Apple Push Notification Service gem

fugitive.vim

A nice Git wrapper for Vim:

View any blob, tree, commit, or tag in the repository with :Gedit (and :Gsplit, :Gvsplit, :Gtabedit, …). Edit a file in the index and write to it to stage the changes. Use :Gdiff to bring up the staged version of the file side by side with the working tree version and use Vim’s diff handling capabilities to stage a subset of the file’s changes.
