Links of the day 12 - 03 - 2015

Today's links 12/03/2015: cryptocurrency landscape, vsphere memory state, hyperscale datacenter system, rowhammer bit flip
  • Bitcoin Landscape : database and categorization of crypto based company [ database here ]
  • Vsphere memory state : What technique vmware use to increase memory density depending of the system memory state . Bonus : memory management performance in vsphere 5.0
  • HDS 8000 : Ericsson HDS 8000 (Hyperscale Datacenter System), built on Intel® Rack Scale Architecture. It uses optical interconnect. Combining a disaggregated hardware architecture with optical interconnect removes the traditional distance and capacity limitations of electrical connections.
  • Project Zero - row hammer : how flipping bit in memory can allow you to gain root access to a physical machine. Basically by aggressively flipping 2 bits you can trigger the third one to switch. ECC can help prevent that to a certain extent but is not completely immune.
