Concatenation of sass value+units. See also: http://stackoverflow.com/a/9862328
// Set sizes without units
$basefont: 20;
$total-width-px: 1169;
$column-width-px: 72;
// Concatenation of units by addition results in conversion to string. This is bad
$basefont-px: $basefont+'px'; // = "20px"
// Conversion to pixels using multiplication
$basefont-px: $basefont*1px; // = 20px;

How to upload a file to a WordPress site via the XML-RPC API. Pretty easy, no? The attachment page if you want a html wrapper to present the file can be found at the following URL: http://yoursite.com/?attachment_id=722 (I left the ID the successful response in as an example)
<?xml version='1.0' encoding='utf-8'?>
<methodCall>

Bare minimum Chrome extension to inject a JS file into the given page when you click on the browser action icon. The script then inserts a new div into the DOM.
// this is the background code...
// listen for our browerAction to be clicked
chrome.browserAction.onClicked.addListener(function (tab) {
// for the current tab, inject the "inject.js" file & execute it
chrome.tabs.executeScript(tab.ib, {
file: 'inject.js'
});

Tinder API Documentation

Tinder API documentation

Note: this was written in April/May 2014 and the API may has definitely changed since. I have nothing to do with Tinder, nor its API, and I do not offer any support for anything you may build on top of this. Proceed with caution

http://rsty.org/

I've sniffed most of the Tinder API to see how it works. You can use this to create bots (etc) very trivially. Some example python bot code is here -> https://gist.github.com/rtt/5a2e0cfa638c938cca59 (horribly quick and dirty, you've been warned!)
