Convert values between RGB hex codes and xterm-256 color codes.

""" Convert values between RGB hex codes and xterm-256 color codes.
Nice long listing of all 256 colors and their codes. Useful for
developing console color themes, or even script output schemes.

Blocking the new version of the NYTimes paywall

The NYTimes has updated their paywall-- it's slightly more sophisticated. The content is no longer hidden behind a big transparent div, but instead is now actually removed from the page entirely. It's still simple to defeat, though. Using adblock plus (or your preferred adblocking device), block the following URLs:

*://*.nytimes.com/*/gwy.js*
*://*.nytimes.com/*/gw.js*

And you're done.

Default git pre-commit hook
#!/bin/sh
#
# An example hook script to verify what is about to be committed.
# Called by git-commit with no arguments. The hook should
# exit with non-zero status after issuing an appropriate message if
# it wants to stop the commit.
#
# To enable this hook, make this file executable.
# This is slightly modified from Andrew Morton's Perfect Patch.
