  • Twitter Shifting More Code to JVM, Citing Performance and Encapsulation As Primary Drivers

    While it almost certainly remains the largest Ruby on Rails based site in the world, Twitter has gradually been moving more and more of its stack to the JVM. Last year the company announced that its back-end message queue had been re-written in Scala, and more recently it moved the search stack to Java, making Twitter search around three times faster.

  • Memory Barriers and JVM Concurrency

    Memory barriers, or fences, are a set of processor instructions used to apply ordering limitations on memory operations. This article explains the impact memory barriers have on the determinism of multi-threaded programs. We'll look at how memory barriers relate to JVM concurrency constructs such as volatile, synchronized and atomic conditionals.

  • Service Dynamics: the lazy man's way

    This article describes "the hardest topic in OSGi, how to deal with service dynamics," based on personal experience. Two factors, concurrency and direct service references, make the problem "fiendishly hard." An import and an export policy should form a comprehensive doctrine for dealing with service dynamics and the article explores two export policies with their corresponding doctrines.
