Data Science gets thrown around in the press like it's magic. Major retailers are predicting everything from when their customers are pregnant to when they want a new pair of Chuck Taylors. It's a brave new world where seemingly meaningless data can be transformed into valuable insight to drive smart business decisions.But how does one exactly do data science? Do you have to hire one of these priests of the dark arts, the "data scientist," to extract this gold from your data? Nope.Data science is little more than using straight-forward steps to process raw data into actionable insight. And inData Smart, author and data scientist John Foreman will show you how that's done within the familiar environment of a spreadsheet....

'Dear PHP, It's over between us. You can keep the kitchen sink, but I want my MVC. With TurboGears, I was able to shed the most heinous FileMaker Pro legacy 'solution' imaginable. It has relationships based on fields that change frequently, causing 'disappearing data.' I replaced it with an easy to maintain TurboGears application. Defunkifying and normalizing many years worth of munged data took twice as long as developing the TurboGears's application itself. TurboGears's excellent set of tools and best-of-breed approach makes it so easy to build applications quickly.' -Isaac Csandl, Manager of Information Technology, Chicago Legal Search, Ltd. 'TurboGears has resulted in significant time savings for rPath. Before it was released, we expected to ...

As data centers grow in size and complexity, enterprises are adopting server virtualization technologies such as VMware, VMotion, NIC teaming, and server clustering to achieve increased efficiency of resources and to ensure business resilience. However, these technologies often involve significant expense and challenges to deal with complex multisite interconnections and to maintain the high availability of network resources and applications. Interconnecting Data Centers Using VPLS presents Virtual Private LAN Service (VPLS) based solutions that provide high-speed, low-latency network and Spanning Tree Protocol (STP) isolation between data centers resulting in significant cost savings and a highly resilient virtualized network. The design guidance,...

Instead of presenting the standard theoretical treatments that underlie the various numerical methods used by scientists and engineers, Using R for Numerical Analysis in Science and Engineering shows how to use R and its add-on packages to obtain numerical solutions to the complex mathematical problems commonly faced by scientists and engineers. This practical guide to the capabilities of R demonstrates Monte Carlo, stochastic, deterministic, and other numerical methods through an abundance of worked examples and code, covering the solution of systems of linear algebraic equations and nonlinear equations as well as ordinary differential equations and partial differential equations. It not only shows how to use Rs powerful graphic tools to construct t...
