# Description: Simple demo to showcase Redis PubSub with EventMachine
#
# Update 7 Oct 2010:
# - This example does *not* appear to work with Chrome >=6.0. Apparently,
#   the WebSocket protocol implementation in the cramp gem does not work
#   well with Chrome's (newer) WebSocket implementation.
#
# Requirements:
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby

NOTE: You will need at least Redis 2.1.6 to use the ZREVRANGEBYSCORE method.

Add players to HIGHSCORES table:

	fossil:~ dczarnecki$ redis-cli 
	redis> zadd HIGHSCORES 1 player_1
	(integer) 1
	redis> zadd HIGHSCORES 2 player_2
	(integer) 1
	redis> zadd HIGHSCORES 3 player_3

# Usage:
#
# - With set/get:
#   App.config.set("some_config_value", "123456")
#   value = App.config.get("some_config_value")
#
# - With hash:
#   App.config["some_config_value"] = "123456"
#   value = App.config["some_config_value"]

# Find latest *n* tweets, but don't repeat tweets by users.
# Example:
#
# If we have the following table:
#
# id  |   user_id   |   created_at
# 1   |     1       |     3 days ago
# 2   |     2       |     3 days ago
# 3   |     1       |     2 days ago

Lies, Damned Lies and Benchmarks

This is just an exercise to measure the performance between Sinatra-like libraries in:

• Elixir v0.4.dev (running on top of the Erlang VM R14B03) with Dynamo;

• Ruby 1.9.2 with [Sinatra Synchrony] v0.0.3 (https://github.com/kyledrake/sinatra-synchrony) + Thin;

• node.js 0.4.7 with [express] v2.3.10(https://github.com/visionmedia/express)
