Browsing Memory the JRuby Way

Why do I like Git?
It's fast.
It's offline, it's online. It's branch-happy, it's merge-happy. It's stash-happy, it's pop-happy. In short, I can develop how I want to without worrying about how mySCM wants my workflow to go. I recently came across a great description of orthogonality in general
use: "[an approach | a tool | a programming language] is orthogonal if
its features can be used without thinking about how that usage will
affect other features." (from http://searchstorage.techtarget.com/sDefinition/0,,sid5_gci283993,00.html) Sweet! That's Git to a tee. I don't have to think about how it's all
going to affect something else. I just use it. If I mess something up,
it's usually only in my local repository. If I can't fix it with some
really easy command, I can just revert the repo. No one on my team is
any the wiser because what I just did didn't affect them (unless I
pushed it out, of course). I've messed things up a lot, but only once
have I had to completely revert the repo -- that was very early in my
use of Git. Git's It! Git it.
Scoring RailsConf speakers by their expletives
I threw up an application on Heroku that scores speakers based on the
number of expletives they use.
Stored Functions in MongoDB
I've been experimenting with stored functions in MongoDB. While generally useful in a JavaScript context, I don't think I will use them from Ruby. Stored Functions run on the server side, making them extraordinarily useful. The problem I am running into is trying to call them from a non-JavaScript client (in this case, Ruby) without using the Database.eval interface to call the function because that will block execution on the server.
Here is some code to store a function in Mongo that will group Asset documents by a virtual attribute (small, medium, large) based on their file_size attribute. The function returns a count of the number of docs within that bucket, the average size, and a total size (in bytes) of the GridFS files to which the assets point.

An interesting read
I'm looking forward to more development with Mongo, and if I can do it
in Smalltalk all the better. Kent Beck has been working on a driver in
VisualWorks and Squeak/Pharo and has written an interesting read about
his experience thus far:

My first post
Posterous seems like a really neat way to blog -- just email, anything...
So, here's my first post, with a picture of our youngest in his sailor outfit.
All of the posts that come before this (after this if you're reading top to bottom) have been imported from my original blog at wordsanddeeds.org (which I will be shutting down soon).
Crazy Michigan Spring
It's April 6th, spring started a couple of weeks ago. And this morning, I woke up to 3 inches of snow on the ground. Ugh...
