Usemon - Usage monitoring of your Java client or server applications during runtime Usemon is a monitoring system for usage trends, response time and dependency analysis of plain Java applications or big multi-clustered Java Enterprise applications running in production.

Ubuntu Offers One Operating System for Any Device - Phone, Tablet, or PC Making a single operating system work on smartphones, tablets, laptops, and TVs is a tricky proposition. You can’t just scale a mobile OS up or a desktop OS down; you have to build software that is flexible enough to adjust for different use cases. And if you want developers’ apps work across multiple devices running your OS, you have to figure out how to make that work, too. This is what Canonical, the U.K. company that developed Linux-based operating system Ubuntu, is trying to do.
