  • 2015-02-19 GCE outage

    40 minutes of multi-zone network outage for majority of instances. ‘The internal software system which programs GCE’s virtual network for VM egress traffic stopped issuing updated routing information. The cause of this interruption is still under active investigation. Cached route information provided a defense in depth against missing updates, but GCE VM egress traffic started to be dropped as the cached routes expired.’ I wonder if Google Pimms fired the alarms for this ;)

  • Listen to a song made from data lost during MP3 conversion

    Ryan McGuire, a PhD student in Composition and Computer Technologies at the University of Virginia Center for Computer Music, has created the project The Ghost In The MP3 [….] For his first trick, McGuire took Suzanne Vega’s ‘Tom’s Diner’ and drained it into a vaporous piece titled ‘moDernisT.” McGuire chose the track he explains on his site because it was famously used as one of the main controls in the listening tests used to develop the MP3 algorithm.
