PHP: Set value if not exist

You know how, in JavaScript, we can set a value to a variable if one doesn't, like this:

name = name || 'joe';

This is quite common and very helpful. Another option is to do:

name || (name = 'joe');

Cross-platform git hooks for Node.js

Here's how this works:

  • Include a git_hooks/ directory in your project, with these two files (plus other hooks if you want, written in a similar style).
  • Add "npm" to your devDependencies in package.json, so that the pre-commit hook can do its magic.
  • Add test and lint scripts to your package.json, e.g.
    "scripts": {
        "test": "mocha",
 "lint": "jshint ./lib --show-non-errors"

Count the number of rules and selectors for CSS files on the page. Flags up the >4096 threshold that confuses IE
function countCSSRules() {
var results = '',
log = '';
if (!document.styleSheets) {
return;
}
for (var i = 0; i < document.styleSheets.length; i++) {
countSheet(document.styleSheets[i]);
}

Some whitespace relating testing with jadejs
<div class="test"><!-- Adding text using | results in a newline AFTER (not before) each line-->foo
bar
baz
</div>
<div class="test"><!--I thought I could use extra | lines to insert additional whitespace but
this currently outputs | characters into the result.

Quick guide to installing rbenv
# Clone rbenv into ~/.rbenv
git clone git@github.com:sstephenson/rbenv.git ~/.rbenv
# Add rbenv to your PATH
# NOTE: rbenv is *NOT* compatible with rvm, so you'll need to
# remove rvm from your profile if it's present. (This is because
# rvm overrides the `gem` command.)
echo 'export PATH="$HOME/.rbenv/bin:$HOME/.rbenv/shims:$PATH"' >> ~/.bash_profile
exec $SHELL
