Michael Barker and Martin Thompson's talk at the last QCon on the LMAX Disruptor, and other nifty lock-free techniques and patterns. 'Martin Thompson and Michael Barker explain how Intel x86_64 processors and their memory model work, along with low-level techniques that help creating lock-free software.'

Amazing stuff from Adrian Cockroft at last week's QCon. Faceted object model, lots of Cassandra automation

Detect near-duplicates; would be good for future Razor-like efficient near-duplicate detection. (slides)

'GC Strategies for Event Processing Systems on the JVM'

intro slideshow to this really nifty-looking distcomp platform

great slides, via HN. recommends a canonical Hadoop long-term store and a quick, realtime, separate datastore for "not yet processed by Hadoop" data

PDFs, docs, links

specifically, Hadoop and Pig for log/metrics analytics, Cassandra going forward; great preso, lots of detail and code examples. also, impressive number-crunching going on at Twitter
