This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
To capture the video (filesize: 19MB), using the free "QuickTime Player" application:
var parser = document.createElement('a'); | |
parser.href = "http://example.com:3000/pathname/?search=test#hash"; | |
parser.protocol; // => "http:" | |
parser.hostname; // => "example.com" | |
parser.port; // => "3000" | |
parser.pathname; // => "/pathname/" | |
parser.search; // => "?search=test" | |
parser.hash; // => "#hash" | |
parser.host; // => "example.com:3000" |
app.filter('bytes', function() { | |
return function(bytes, precision) { | |
if (isNaN(parseFloat(bytes)) || !isFinite(bytes)) return '-'; | |
if (typeof precision === 'undefined') precision = 1; | |
var units = ['bytes', 'kB', 'MB', 'GB', 'TB', 'PB'], | |
number = Math.floor(Math.log(bytes) / Math.log(1024)); | |
return (bytes / Math.pow(1024, Math.floor(number))).toFixed(precision) + ' ' + units[number]; | |
} | |
}); |
Two years ago, as part of GSoC 2011, I started working on an implementation of composite fields as a means to support multi-column primary keys in models. While the project was successful, the timeframe wasn't sufficient to finish it and get it into a state where it
When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:
const Article = require('../../../../app/models/article');
Those suck for maintenance and they're ugly.

So, you're a developer testing lots of codes and you want to ensure that you don't accidentally send out email to people during testing.
However, you also want to actually view emails in a real email client, not a console.
This is how you can do it using Ubuntu and Exim ensuring that the email gets sent out through Google apps.

# Usage: mv oldfilename | |
# If you call mv without the second parameter it will prompt you to edit the filename on command line. | |
# Original mv is called when it's called with more than one argument. | |
# It's useful when you want to change just a few letters in a long name. | |
