Hi everyone, I'm Chris Wanstrath.

When Jeremy asked me to come talk, I said yes.  Hell yes.  Immediately.  But
then I took a few moments and thought, Wait, why?  Why me?  What am I supposed
to say that's interesting?  Something about Ruby, perhaps.  Maybe the
future of it.  The future of something, at least.  That sounds
keynote-y.


## Checkstyle pre-commit hook
#!/usr/bin/perl
#
# Pre-commit hook for running checkstyle on changed Java sources
#
# To use this you need:
# 1. checkstyle's jar file somewhere
# 2. a checkstyle XML check file somewhere
# 3. To configure git:
#   * git config --add checkstyle.jar <location of jar>
#   * git config --add checkstyle.checkfile <location of checkfile>

## wget_spider_https
http://addictivecode.org/FrequentlyAskedQuestions

To spider a site as a logged-in user:

1. post the form data (_every_ input with a name in the form, even if it doesn't have a value) required to log in (--post-data).
2. save the cookies that get generated (--save-cookies), including session cookies (--keep-session-cookies), which are not saved when --save-cookies alone is specified.
2. load the cookies, continue saving the session cookies, and recursively (-r) spider (--spider) the site, ignoring (-R) /logout.

# log in and save the cookies
wget --post-data='username=my_username&password=my_password&next=' --save-cookies=cookies.txt --keep-session-cookies https://foobar.com/login

## dirinbash
# taken from http://www.daybarr.com/blog/how-to-list-all-subdirectories-of-a-directory-in-bash

To (non-recursively) list all children of a directory in bash
find . -type d -maxdepth 1 -mindepth 1

and to do the same but omitting the .svn directory (subversion's working copy info)
find . -type d -maxdepth 1 -mindepth 1 -not -name .svn

Useful in constructs such as
view sourceprint?

                JIT for dummies: JIT compiling RPN in python
              
          
    If you don't care about the explanation, scroll down to find the code, it's 50 some odd lines and written by someone who doesn't know any better. You have been warned.
What it does

This is a very simple proof of concept jitting RPN calculator implemented in python. Basically, it takes the source code, tokenizes it via whitespace, and asks itself one simple question: am I looking at a number or not?
First, let's talk about the underlying program flow. Pretend that you are a shoe connoisseur with a tiny desk. You may only have two individual shoes on that desk at any one time, but should you ever purchase a new one or get harassed by an unruly shoe salesman without realizing that you have the power to say no (or even maybe?), you can always sweep aside one of the two shoes on the desk (the one on the right, because you're a lefty and you feel that the left side is always superior) onto the messy floor, put the other shoe on the right hand side, and then place your newly acquired shoe in
