The avconv utility can be made to work in 'the Unix way' by specifying stdin and/or stdout instead of filenames for the input and output respectively. See: http://libav.org/avconv.html#pipe

Example:

cat input.ts | avconv -i pipe:0 -f mp4 -movflags frag_keyframe pipe:1 | cat > output.mp4

Using node's require('child_process').spawn(), we can pipe streams of video data through avconv's stdin and stdout and thus Stream All The Things.

var fs = require('fs');

An ongoing project to catalogue all of these sneaky, hidden, bleeding edge selectors as I prepare my JSConf EU 2012 talk.

Everything is broken up by tag, but within each the selectors aren't particularly ordered.

I have not tested/verified all of these. Have I missed some or got it wrong? Let me know. - A

A friendly reminder that you may need to set this property on your target/selected element to get the styling results you want:

-webkit-appearance:none;

Run VMware Fusion headless at Mac OS system startup.

I heard you like headless VMs on your Mac so I wrote this script for your launchds.

Assumptions

• Tested on Mac OS X 10.6.4 with VMware Fusion 2.0.5 and 3.1.1.
• A interactive user automatically logs into the system at startup. I had some issues trying to get this running without an interactive user logged in. I automatically log in for Airfoil Speakers anyway.
• Your virtual machines live in /Virtual Machines
