Today's links 13/02/2015: Scalable and resilience web site, CAP theorem, automated log analyzer and Exascale HPC challenges

• Scalable and Resilient website : lessons learned from all the biggest sites on the internet about how to build scalable and resilient architectures. 
• Perspectives on the CAP theorem : paper summary that show the CAP theorem in the broader context of a family of results in distributed computing theory that shows impossibility of guaranteeing both safety and liveness in an unreliable distributed system.
• Sequence: Automated Analyzer for Reducing 100,000's of Log Messages to 10's of Patterns
• Algorithmic and Software Challenges atExtreme Scales : presentation by Jack Dongarra  , quite redundant as the same theme are pretty common to all HPC exascale challenge : matrix operations optimizations, power, resilience, scalability, etc..
