Make and let communication happen. Avoid dead communication channels. Don’t control, don’t manipulate. Harvest and refine information pieces. Deliberately leave pain points for the community to remedy. - Sebastian Bergmann

Communications and cooperation between development and operations isn't optional, it's mandatory. Flickr takes the idea of "release early, release often" to an extreme - on a normal day there are 10 full deployments of the site to our servers. This session discusses why this rate of change works so well, and the culture and technology needed to make it possible. - Sebastian Bergmann

Kestrel is a powerful but simple messaging server that enables reliable distributed queuing with an absolutely minimal overhead. It speaks the memcache protocol for maximum cross-platform compatibility. Any language that speaks memcache can take advantage of Kestrel's queue facilities. - Sebastian Bergmann

MILEPOST GCC is the first machine learning enabled open-source self-tuning research compiler that can adapt to any architecture using iterative feedback-directed compilation, machine learning and collective optimization. It combines the strength of the production quality GCC that supports more than 30 families of architectures and can compile real, large applications including Linux, and the flexibility of the Interactive Compilation Interface that transforms GCC into a research compiler. It is currently based on predictive modeling using program and machine-specific features, execution time, hardware counters and off-line training. MILEPOST GCC includes static program feature extractor developed by IBM Haifa. MILEPOST/cTuning technology is orthogonal to GCC and can be used in any future adaptive self-tuning compiler using common Interactive Compilation Interface. - Sebastian Bergmann
