Jester is written in Python, using Redis for storage.

I’ve created a tiny Domain Specific Language for defining rules using the pyparsing library.

A couple examples of rules:

create rule on game_play award 5 points
create rule on game_play award badge game_addict when game_play occurs 5 times in 1 day

This project is in the very early stages and is not yet functional as of this posting. However, I expect to have a rough working version of it up by the end of next week.

I fixed it by doing the following:

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

sudo ln -s /usr/local/mysql/lib /usr/local/mysql/lib/mysql

I’m not sure if it matters, but I’ve got MySQL 5.5 installed.

Well, fortunately it’s pretty easy to fix. Edit your .git/config, adding the remote and merge lines under your master branch.
[branch "master"]
remote = origin
merge = refs/heads/master


Next time you’re on the master branch and pull, it’ll fetch the latest code off the master branch on the origin and merge into your local master.

The fix is to use python to call easy_install instead of using the Apple provided one.

sudo python -m easy_install pymongo
