In terms of language popularity, much of the late 90s and early 2000s revolved around so called "managed" languages, such as Java or C#. Currently however, industry seems to be turning back more and more to native languages, and in particular two mainstream ones - C++ and Ada.

Rich Hickey discusses simplicity, why it is important, how to achieve it in design and how to recognize its absence in the tools, language constructs and libraries.

Reactive-web is a new framework for writing highly interactive and dynamic web applications. It's written in Scala , sits on top of Lift, and uses the Functional Reactive Programming library reactive-core (it's in the same repository). As in GWT, you can code the user interface in the same language as the rest of your application (except in Scala instead of Java), rather than writing JavaScript. Unlike GWT, however, you don't need an extra build step to convert your code to JavaScript. You can easily combine code that runs on the browser with code that runs on the server. And, you can declare dynamic relationships between components, like binding in Flex/JavaFX/etc. (only much more powerful).

DRBL (Diskless Remote Boot in Linux) is a solution to managing the deployment of the GNU/Linux operating system across many clients. Imagine the time required to install GNU/Linux on 40, 30, or even 10 client machines individually! DRBL allows for the configuration all of your client computers by installing just one server machine. DRBL provides a diskless or systemless environment for client machines. It works on Debian, Ubuntu, Mandriva, Red Hat, Fedora, CentOS and SuSE. DRBL uses distributed hardware resources and makes it possible for clients to fully access local hardware.
