“Looping” an audio file with Sox, Lame and mkfifo

Published under Technology

Today I needed a very long (3 hour) MP3 audio file to use for an experiment; a test file with some music on it. My first thought was to start a MP3 audio recorder, turn on the radio, and leave for 3 hours. But impatience is among the three great virtues of a programmer, so […]

Why I will also never deploy with Java Web Start again

Published under Technology

Keith Lea pointed out that he will never deploy with Java Web Start again. With Web Start in its current form, he’s be deploying with it long before I will use it again.  “Never” is much too soon.. here is why, echoing and expanding on Keith’s experiences.
