This document contains some notes I have gathered while I was trying to setup a redis service using boot2docker running on OS X. This won't cover what Docker is, see Docker website for details.

Installing boot2docker

First, install Virtualbox and follow the steps at http://docs.docker.com/installation/mac/

Since Docker only runs on Linux, boot2docker runs a virtual machine in Virtualbox (or VMWare etc), however you can run the docker command on OS X

1. Levenshtein distance - similarity between words
2. Damerau-Levenshtein distance - similarity between words
3. Hamming distance - similarity between words
4. BK Tree - spell checker implementation in O(log n). Also applied Levenshtein.
5. Suffix Tree/Suffix Array - string pattern
6. Random Indexing - Finding context in text
