The developers at Digg have come up with an interesting way to speed up load times of high performance websites. They have taken the idea that reducing the number of HTTP requests per page speeds up website performance, and come up with a technique called MXHR (Multipart XMLHttpRequests). MXHR works by bundling files, sending them through a single request, then separating them for use once they head down the pipe.

JSLint is a JavaScript program that looks for problems in JavaScript programs.

When C was a young programming language, there were several common programming errors that were not caught by the primitive compilers, so an accessory program called lint was developed which would scan a source file, looking for problems.

Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages, enabling Java and other programmers to be more productive. Code sizes are typically reduced by a factor of two to three when compared to an equivalent Java application.

Many existing companies who depend on Java for business critical applications are turning to Scala to boost their development productivity, applications scalability and overall reliability.

In computer science, the Actor model is a mathematical model of concurrent computation that treats "actors" as the universal primitives of concurrent digital computation: in response to a message that it receives, an actor can make local decisions, create more actors, send more messages, and determine how to respond to the next message received.

Google has added the Java runtime to its App Engine, that (semi-)free service that lets you build and host web apps on Google's very own cloud distributed infrastructure.

When App Engine was first introduced, almost a year ago to the day, it stuck with Python, a favorite among code-happy Google Oompa Loompas. But after countless request from developers outside the Mountain View Chocolate Factory, the platform has now embraced Java as well.

The Persevere project is an open source set of tools for persistence and distributed computing using intuitive standards-based JSON interfaces of HTTP REST, JSON-RPC, JSONPath, and HTTP Channels. The core of the Persevere project is the Persevere Server. The Persevere server includes a Persevere JavaScript client, but the standards-based interface is intended to be used with any framework or client.
