Pokebin

• like Pastebin but for Pokemon teams
• anyone can access the site and create an annonymous team
  • teams get urls like: http://pokebin.io/963fc4d
  • annonymous teams persist for 1 month and then are marked for deletion
    • teams marked for deletion are deleted when they are not visited for 2 consecutive days
  • spam filters and rate limiting to curb abuse
• users can optionally sign up to have their teams persist forever
• JSON api: http://pokebin.io/963fc4d.json

Persephone

Persephone provides a HTTP-based, RESTful web API wrapper around Capistrano tasks. The intent is to allow Capistrano tasks to be executed via web interfaces, chat bots, native applications, etc. without having to manually SSH in to a server and issue commands.

Installation

Persephone is a simple Sinatra app that is distributed as a gem.

Add the gem to your Gemfile:

aergonaut

namespace :db do
  namespace :sql do
    desc "Load database from SQL dump"
    task :load => [:environment, :reset] do
      ARGV.shift
      file = ARGV.shift
      
      name_and_extensions = file.split(".")
      name = name_and_extensions.shift
      extensions = name_and_extensions
