From the abstract: “With mobile apps becoming more and more reliant on web services, managing network code has become one of the central responsibilities of the mobile application architect. This talk will cover Robospice, an open-source networking library for Android. Robospice streamlines some the most common networking tasks on Android, such as: –asynchronous background threading –network request, response and error handling –binding of JSON, XML and other data interchange types to Java objects –robust response caching –support for several library…

From the abstract: “Over the past two years Tumblr has experienced tremendous growth, with traffic growing more than 10x from less than 1.6B pageviews a month to nearly 20B pageviews a month. Tumblr started in 2007 as a traditional LAMP application with some memcache usage. Over the past two years Tumblr has moved towards a service oriented distributed system built on the JVM and supported by heavily sharded MySQL along with HBase and Redis. In this talk we’ll review the…

From the abstract: “In today’s production environments, tremendous amounts of work can be performed on servers running the JVM with dozens of cores, yet in just a few years we could have machines that have thousands of cores. Parallelizing work in such a “manycore” environment is a hot topic, as is managing concurrency with so many possible threads executing at the same time. Will deterministic results be impossible in such a world? Will the JVM evolve to have more hardware…

Our day 1 keynote presentation was delivered by Claudia Perlich of Media Six Degrees. She’s been working in the data science field long before it became a hugely popular career choice. This keynote was both filmed and screen-captured, so you’ll not only hear Ms. Perlich and watch her slides, but view the presentation as it was given. Thanks to @Stephen_Metzger for ALL of his video expertise and for his team recording video on this one. From the abstract: “The Harvard…

From Doug Lea’s abstract: “Creating components based on concurrent and parallel algorithms and data structures often requires more attention to “engineering” issues not seen with most other libraries. Components created in the “obvious” way sometimes turn out to be wrong, to perform poorly, or are unusable in most applications, because the abstractions in which they are expressed are leaky, imprecise, or incorrectly specified. While many of these issues are encountered in other aspects of concurrent programming, the impact is accentuated…

From Alex’s abstract: “Clojure’s approach to data is significantly different than other popular languages, and somewhat different even than its Lisp heritage. On one hand, Clojure provides a small core set of immutable, persistent data structures. On the other, Clojure uses functional programming to provide a rich set of data manipulation functions. These two pillars of Clojure are fused together through the “sequence” abstraction. Because of sequences, Clojure developers expect that almost any function works with almost any composite data….

When you are faced with the challenge of tuning JVM, you can find a wide variety information. Yet, almost always the information is rather specific in the type of tuning, or specific to a type of problem. Seldom can you find information that tells abstracts the details into a higher level and simplifies it into a set of fundamentals and principles. This is what you can expect to hear and learn in this session. The first important thing to do…
