# My sister and brother inlaw got into geocaching 
# after I showed them the android app for it... anyhow I was in Olympia for my m
# oms birthday and I showed them that puzzle cache (http://coord.info/GC1JD07)... 
# and when my manual math ended up being off by one in my "B" calculation  (21-19 
# != 3) I uh, got carried away once I got back to seattle.  :(

# I only got this carried away though 'cause I'm trying to build a presentation 
# on parsers for a conference and I thought this was a reasonable mini language wh
# ere I could show the "quick" hour long solution I came up with versus the actual
# parser one I'll present.  I also could've done this faster by just coding this

Javascript Obfuscation, Minification and why it doesn't really matter.

I'm working on placing some geocaches[http://www.geocaching.com] and they must be 0.1 miles away from other geocaches.  Being a programmer I thought, well, let's just write a bookmarklet to augment the geocaching website with a radius around the caches displayed on the map.  So I googled for chunk of code that would do this because I'm lazy.  The first tool was http://www.freemaptools.com/radius-around-point.htm and its UI was clunky but the output looked good enough to me.  So I dig into the source... and *gasp* what is this?

10111010001000010111010000111101010101101101110100010101010100100001...
http://www.freemaptools.com/script/radius-around-point.js

At that point, I could've just looked for the next site but I have a few tricks up my sleeve since I've had to dig into ridiculous javascript for serveral of my jobs... The first trick is just use chrome developer tools, it'll probably get you 90% of the way there... and look, it does!

Back Button Boy: Do not try and hit the back button. That's impossible. Instead... only try to realize the truth.
Neo: What truth?
Back Button Boy: There is no back button.
Neo: There is no back button?
Back Button Boy: Then you'll see, that it is not the app that goes back, it is only yourself.
