Music Smasher is a smash up of popular music streaming service APIs. I developed it to simplify the task of searching across Spotify, Rdio, Grooveshark, and other catalogs to find out who has the music you love, giving you more information for choosing a streaming service.

Weird Spotify Compression Artifacts
This is my personal blog. The views expressed on this page are mine alone and not those of my employer. Spotify Artifacts Showcase I love Spotify.

Exact MP3 Recompression
Let's say you have a library for decoding MP3* streams, and your library exposes some API methods that provide access to the resulting uncompressed PCM audio stream.

Human Birdwings Hoax
This human flight hoax has been picked up by all the tech and gizmo blogs within the past 12 hours. http://www.wired.com/wiredscience/2012/03/human-bird-wings/ They have Youtube videos going back several months, working machines, blueprints, blogs, press kits... pretty impressive.
