OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

caged

var svg  = document.getElementById('graph'),
    xml  = new XMLSerializer().serializeToString(svg),
    data = "data:image/svg+xml;base64," + btoa(xml),
    img  = new Image()

img.setAttribute('src', data)
document.body.appendChild(img)

simple 4mb buffer proxy benchmarks

the goal: to do fast virtual host routing, e.g. to have a single process on a machine listening on port 80 and proxying data based on HTTP Host to other non-port-80 web processes on the same machine

many people use nginx for this because nginx is faster than node is currently for data-heavy applications (see below)

about these benchmarks

they use the JS proxies from https://github.com/substack/bouncy/tree/master/bench
