We liked the program's interface, especially how it listed every element that makes up an aquarium and allowed for quick glances at each one's status. We never touched the instructional Help file because the program was so intuitive. We were impressed that every element from the water's PH balance, to food, to the electricity used allowed for its data to be inputted and monitored for a comprehensive … Read more

Home schoolers, high school tutors, and students needing additional mathematics study will find this many-featured app a handy addition to their toolbox. It provides assistance for grasping two-dimensional function graphs with animation, analyzing functions, understanding analytic geometry, solid geometry, and more.

Math Studio launches a three-paned interface similar to the familiar e-mail client design: the upper-left vertical pane is a graph manager, the lower-left pane is a result editor, and the large pane on the right is a plotting area for displaying graphs. However, the cluster of icons in the three toolbars aligned along the interface's top may intimidate … Read more

I read with interest that open-source messaging vendor Open-Xchange is building a "meta-address book" service that brings together your contacts from various social networking sites into "one continuous stream of updating contacts." While promising, I don't think it goes far enough.

It's nice to have a centralized address book. It's even better to analyze the connections between contacts and deliver services based on that data, as I recently argued.

One area in which this information would be hugely valuable is in connecting enterprises through their respective employees. Think about it: most companies spend … Read more
