'Bobtail: Avoiding Long Tails in the Cloud' [pdf]
'A system that proactively detects and avoids bad neighbouring VMs without significantly penalizing node instantiation [in EC2]. With Bobtail, common [datacenter] communication patterns benefit from reductions of up to 40% in 99.9th percentile response times.'

Excellent stuff -- another conclusion they come to is that it's not the network's fault, it's the Xen hosts themselves. The EC2 networking team will be happy about that ;)

Removing DRM Boosts Music Sales by 10%
Based on a working paper from University of Toronto researcher Laurina Zhang
Comparing album sales of four major labels before and after the removal of DRM reveals that digital music revenue increases by 10% when restrictions are removed. The effect goes up to 30% for long tail content, while top-selling albums show no significant jump. The findings suggest that dropping technical restrictions can benefit both artists and the major labels.
