Simple snippet for cross-platform .pid management in NodeJS. I use it for managing NodeJS apps with supervisord and monit

Convert SVG's to PNGs. This works OK if the SVG's styles are inline. The SVG element must contain an xmlns attribute. Webkit also requires you specify a font size on `text` elements.
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)

This snippet of code is syntactically valid in both PHP and Java, and produces the same output in both.
