It’s HighScalability Time:
- 50 million in 50 days : Draw Something downloads; 40 million concurrent users : Skype
- Key to making sensors ubiquitous is getting the BOM cost down. Here’s a dream way of making that happen: Bye-Bye Batteries: Radio Waves as a Low-Power Source. “Silicon technology has advanced to the point where even tiny amounts of energy can do useful work.” No batteries == cheaper, smaller products == ubiquity.
- The MySQL “swap insanity” problem and the effects of the NUMA architecture. Jeremy Cole with a spectacular article on maleextra review add a comment website the differences between NUMA and SMP/UMA systems and the mostly unsatisfactory tricks required to get MySQL to perform on NUMA systems. There are really two issues: the evils of an OS controlled swap and NUMA performance effects due to a single node (in the NUMA sense) running out of memory. This is the kind of stuff you only see when you push your systems to the edge.
