Redis based IP blacklist for Nginx (LUA)
-- a quick LUA access script for nginx to check IP addresses against an
-- `ip_blacklist` set in Redis, and if a match is found send a HTTP 403.
--
-- allows for a common blacklist to be shared between a bunch of nginx
-- web servers using a remote redis instance. lookups are cached for a
-- configurable period of time.
--
-- block an ip:
-- redis-cli SADD ip_blacklist 10.1.1.1
-- remove an ip:

# 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

/* This is when a refactoring really pays off.
*
* In order to make your code more modular, avoid hard-coding assumptions (or refactor them away).
* The most fundamental, anti-modular assumption in Object-Oriented software is the concrete type of objects.
* Any time you write "new MyClass" in your code (or in Ruby MyClass.new) you've hardcoded
* an assumption about the concrete class of the object you're allocating. These makes it impossible, for example,
* for someone to later add logging around method invocations of that object, or timeouts, or whatever.
*
* In a very dynamic language like Ruby, open classes and method aliasing mitigate this problem, but
* they don't solve it. If you manipulate a class to add logging, all instances of that class will have

Emulating ARM on Debian/Ubuntu

You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

Running ARM programs under linux (without starting QEMU VM!)

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux
