Discovered an interesting algorithm for finding longest palindrome by playing with sequences in a text editor. Anyone know if there's a name for this algorithm?

Worst running time is O(n^2), which is better than the naive implementation of O(n^3) but not as efficient as some O(n) implementations (http://www.akalin.cx/longest-palindrome-linear-time). In general, assuming a non-pathological case, running time is around 2n * m where n is the length of the string and m is the mean length of all palindromes. For non-pathological cases (i.e. human sentences), n is often logarithmic (log n) and fast approaches 1 as n increases. This puts the average case complexity at around n log n and best-case n.

Developed as a solution to: http://www.therubygame.com/challenges/4

Algorithm

Original hand-work to discover a pattern:

# Usage: git-unmerged branch1 branch2
# 
# Shows all the non-common commits in the two branches, where non-common
# commits means simply commits with a unique commit *message*.

proc getlog branch {
    lrange [split [exec git log $branch --oneline] "\n"] 0 400

Zero downtime deploys with unicorn + nginx + runit + rvm + chef

Below are the actual files we use in one of our latest production applications at Agora Games to achieve zero downtime deploys with unicorn. You've probably already read the GitHub blog post on Unicorn and would like to try zero downtime deploys for your application. I hope these files and notes help. I am happy to update these files or these notes if there are comments/questions. YMMV (of course).

Other application notes:

• Our application uses MongoDB, so we don't have database migrations to worry about as with MySQL or postgresql. That does not mean that we won't have to worry about issues with the database with indexes being built in MongoDB or what have you.
• We use capistrano for deployment.

Salient points for each file:
