ronny / check_box.js.coffee
Created August 17, 2014 05:04
ReactJS CheckBox component that works like Rails' `f.check_box`
_ = require('underscore')
React = require('React')
{span, input} = React.DOM
# Check box that always submits a value, even if unchecked. This uses the same
# trick as Rails's `f.check_box`: a hidden input with the same name as the
# checkbox but with a value of 0 that appears before the actual checkbox. When
# the checkbox is checked, the checkbox's value will be submitted, when it's
# unchecked, then the hidden input value of 0 will be submitted.

Ant colony simulation written in Clojure by Rich Hickey, from his presentation on Clojure Concurrency – http://www.youtube.com/watch?v=dGVqrGmwOAw – modified by me to work in Clojure 1.5, and also to make it look nicer.

Stevey's Google Platforms Rant
Stevey's Google Platforms Rant
I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.
I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out.
