Scrum beyond software (think in lamp version)thinkinlamp
This document discusses lessons learned from translating a book about agile practices using agile principles. It notes challenges with assumptions vs reality, communication visibility, planning and tracking, collaboration, quality, and work procedures. It provides recommendations such as using Kanban techniques like limiting work in process, visualizing work, and frequent checkpoints to improve synchronization and prevent delays. The key is to focus on communication, feedback, self-organization, and simple tools while inspecting and adapting practices.

David Jiang presented InnoSQL, a new branch of MySQL that features a flash cache for the InnoDB storage engine. The flash cache provides higher performance than using an SSD as the durable storage alone. It caches both reads and writes using SSDs and employs techniques like merge writes and sequential writes to optimize for SSD performance. Benchmark results showed the flash cache improved throughput for the TPC-C workload by around 2x compared to using SSDs as the durable storage directly.
