Memory efficient Ubuntu VMs - Attila G

https://coderwall.com/p/a56j3w

I wrote about virtualisation recently when I found out how to cut my virtual machines’ memory consumption by as much as 50%. In this article I explain what the motivations were and how to create a low memory footprint Ubuntu server for production and development use cases. Also, my recent article that I posted on coderwall has made it into the hot articles list.

Please consider up voting it if you think that the article is well written and is useful to you.

The great thing about the Mozilla API is its ability to access low level raw data and write it out to file. In the first incarnations of the Webkit Audio API this was a much harder task! This article though, shows you how to go from a sound input to lossless wav file.

Hyperaudio - Making Audio a First Class Citizen of the Web - Andy M

http://vimeo.com/69612769 This is an interesting discussion into the place of audio on the web and what the Web Audio API’s are capable of. Not only in terms of music and sound but communication and mobile technology too!

Yet another X things in X time period project! This immensely bold undertaking is chronicled in a series of blog posts by someone who started out with no coding experience whatsoever.
