mainly marketing articlle by cofiiunder What if you didn't have to do any of this funny business to get scalability and reliability? What if the JVM had access to a service that you could plug into to make its heap durable, arbitrarily large, and shared with every other JVM in your application tier? Enter Terracotta, network-attached, durable virtual heap for the JVM. In the spirit of full-disclosure, I'm a co-founder of Terracotta and work there as a software developer. Terracotta is an infrastructure service that is deployed as a stand-alone server plus a library that plugs into your existing JVMs and transparently clusters your JVM's heap. Terracotta makes some of your JVM heap shared via a network connection to the Terracotta server so that a bunch of JVMs can all access the shared heap as if it were local heap. You can think of it like a network-attached filesystem, but for your object data; see Figure 1.
By Joey Hess, Wikis are not just for encyclopedias and Web sites anymore. You can use Ikiwiki in combination with your revision control system to handle issue tracking, news feeds, and other needs of a software project. The wiki can make your bug reports as much a part of your software project as its code, with interesting results. Ikiwiki is a wiki engine with a twist. It's best described by the term "wiki compiler". Just as a typical software project consists of source code that is stored in revision control and compiled with make and gcc, an ikiwiki-based wiki is stored as human editable source in a revision control system, and built into HTML using ikiwiki. Ikiwiki uses your revision control system to track changes and handle tasks such as rolling back changes and merging edits.
