I thought we’d have another decade or two until the machines took over.
The scariest part of this single program was that its millions of quotes accounted for 10 percent of the bandwidth that is allowed for trading on any given day, according to Nanex. (The size of the bandwidth pipe is determined by a group made up of the exchanges called the Consolidated Quote System.)

As a web developer, I hadn’t decided to focus on front-end work until another developer told me about Firebug.
When I started targeting mobile, I switched to the Developer Tools suite (DevTools) built in to Google’s Chrome browser.
Two years later and I’m just beginning to realize what I’ve been missing. I was on the /r/javascript forum on Reddit and the top post is a slide deck showing forty pro tools and tips I had no clue about.
I’ve been working with JSLint profiling and what they say is true: minification is more efficient if you write your JavaScript following certain JavaScript sub-standards (I know there’s a better way to phrase that).
File Sizes
Original: 27,542 bytes
Original (minified): 21,179
Linted: 30,714
Linted (minified): 20,899
Here’s the scoop. The original file size was 27,542 bytes. When rewritten using Crockford’s “Good Parts” settings in JSLint the file size grew to 30,714 bytes (by ~12%). The original file size minified to 21,179, a savings of 6,363 bytes (~23%).
Here’s where it gets cool.
Linting the file added 3,172. But doing so allowed the compression to reduce the file size to 20,899 bytes, shrinking it by 31% and making it even smaller than the original file was when it was minified!
Awesome and weird, right?
