From the abstract: “Patterns and functional programming aren’t often mentioned together, but they’re related in a couple of ways. First, most of the classic object oriented design patterns fade away in languages with functional features. Second, functional languages have their own set of interesting patterns, which can often be given first class language support. In this talk, based on the forthcoming Pragmatic Press book Functional Programming Patterns, we’ll examine a few of each type of pattern, and show how adding…

From the abstract: “HTML5 Boilerplate is an extremely popular front-end template that helps lay the ground work for building fast, robust, and adaptable web apps or sites. This project is the product of many years of iterative development and combined community knowledge. It tries to be agnostic of any specific, higher-level development philosophy or framework. Rather than adding features, the core project is now significantly smaller than when it was first released. The original creators of the project having long…

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…

Philly ETE Screencast #7 – Doug Lea – Engineering Concurrent Library Components

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…

PhillyETE Screencast #6 – Alex Miller – Clojure: Enemy of the State

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….
