Terracotta is out to cure skimpy cache by making Ehcache really, really big, 1TB in fact, a size only a few people can use right now, but just you wait, it says, the day is upon us when practically everybody with a database will want it to be in-memory. The biggest caches these days are still 100GB-200GB and they’re a lot of work to build. Maybe there are two or three that hit 200 GB. The average, on the other hand, is more like sub-20 gigs. Terracotta swears it’s made it easy to store over a terabyte of data and hundreds of millions of entries in a single cache, so data retrieval is a whole lot faster and clouds and virtualization aren’t bottlenecked.

Block storage is a key foundation to most file systems. File sharing and file locking are important processes for sharing cloud data resources, and for eliminating race conditions. Efficient implementation can make a significant mark on your system's and applications' performance levels. In this article, we use an open source example -- cloud platform Eucalyptus and its storage component Walrus -- to demonstrate how to modify block storage to improve the file-sharing and -locking mechanisms. Learn how to install Eucalyptus so you can deliver a top-notch Infrastructure-as-a-Service platform.

The code is polished, the site map is frozen, and the UI is dripping with gorgeous colors. Everything is perfect -- aside from worrisome reports that some beta testers are finding that buttons are slow or even completely unresponsive. The AJAX calls that seemed so snappy in the lab were working well -- except for those inexplicable moments when they aren't. And those moments can't be duplicated.

Following on from the problems that Eclipse users were experiencing with Java 6 Update 21, Oracle has rebuilt the release. If you look at the release notes it's now up to build 7. This build regresses the rebranding of the files' Company Name from "Oracle" back to "Sun Microsystems, Inc.".

This should mean that any Eclipse users who haven't upgraded to Java 6 Update 21 won't notice any problems when they do and for those who started using build 6 you can just download and reinstall with the latest Java update. It also gives Eclipse (and any other similarly affected applications) a chance to update their code in time for the release of JDK 7 when the rebranding changes will go ahead.

The Java language is more than you need for some projects, but scripting languages are famously lacking on the performance front. Find out how the Java Scripting API (javax.script) delivers the best of both worlds, by allowing you to invoke scripts from your Java programs, and vice versa.
