Best New Mashups: Vizualization Mashups Using Twitter, Twilio and Klout
With data being both more plentiful and accessible than ever, tools that help users quickly make sense of it become increasingly valuable. As expected, much of the data being used comes from social sites. We come across mashups that access this data and provide interesting ways of looking at it from influence circles, tweet impacts and search results.
Ars Technica Guide to Virtualization: Part I
In 2003, Intel announced that it was working on a technology called "Vanderpool" that was aimed at providing hardware-level support for something called "virtualization." With that announcement, the decades-old concept of virtualization had officially arrived on the technology press radar. In spite of its long history in computing, however, as a new buzzword, "virtualization" at first smelled ominously similar to terms like "trusted computing" and "convergence." In other words, many folks had a vague notion of what virtualization was, and from what they could tell it sounded like a decent enough idea, but you got the impression that nobody outside of a few vendors and CIO types was really too excited. Fast-forward to 2008, and virtualization has gone from a solution in search of a problem, to an explosive market with an array of real implementations on offer, to a word that's often mentioned in the same sentence with terms like "shakeout" and "consolidation."In the previous installment of the Virtualization Guide, I talked in general ways about the exculsive hardware access privileges that the OS reserves for itself. Now it's time to nuance that picture a bit, so you can see exactly how the OS retains the upper hand over applications and users. This brief installment sets the stage for Part III, which will talk in some detail about Intel VT. A microprocessor does more than just blindly run whatever instructions are loaded into its front end, without regard for where those instructions came from. Microprocessors are in fact "aware" of the OS, and they provide direct hardware support for enforcing divisions between components of the hardware/software stack that I described in the previous article. In order to keep applications from usurping any part of the OS's privileged access to system hardware, processors provide a mechanism that allows different programs to run at different privilege levels .

The Best Tools for Visualization
Visualization is a technique to graphically represent sets of data. When data is large or abstract, visualization can help make the data easier to read or understand. There are visualization tools for search, music, networks, online communities, and almost anything else you can think of. Whether you want a desktop application or a web-based tool, there are many specific tools are available on the web that let you visualize all kinds of data. Here are some of the best: Visualize Social Networks
