After a Hiatus…

So it’s been a long time since I’ve posted anything so I thought I’d give an update so that there is something here.

I love my job to death! I work with awesome people and have a lot of cool stuff to do. I’m also climbing three times a week, which doesn’t leave me with a lot of time to code or be at home. When I am home I’m working on a STOMP library for the Arduino Ethernet Shield.

The STOMP library is going to be used in part of a home automation system my partner and I are working on. I say “working on” because she’s just as busy as I am and doesn’t have much time to work on all of the projects she’s got on the go.

So I’m still around and just really busy!

Random Snippet: Soundex

This bit of code is the Soundex algorithm based on some C written by a friend of mine (Hi Jen!). She writes really compact C (read: hard to read) and it took me a long time to understand what the code she wrote did.

So here is the annotated version of the code (correlates to the Rule numbers on Wikipedia).

PLAIN TEXT

RUBY:

class String
@@sem = [ 0,1,2,3,0,1,2,0,0,2,2,4,5,5,0,1,2,6,2,3,0,1,0,2,0,2 ] # Letter codes, Rule 3
def to_soundex
s = self.upcase
chars = s[1 .. s.size - 1].split(//) # Split the word into characters to encode
ret = s[0,1] # Rule 1
chars.each_index do |i|
c = chars[i]
next if ( c <'A' or c> 'Z' ) # Not a letter
next if i>0 and c == chars[i - 1] # Rule 4
d = @@sem[ c[0] - 'A'[0] ] # Encode it
ret += d.to_s unless d == 0 # Rule 2
end
ret += "0000" # Rule 5
ret[0..3] # Rule 5
end
end

It was fun to write and it works well.
