'The Art of the Data Center' highlights data center innovations
Despite recent news articles regarding energy waste in the data center industry, there are plenty of designs that stand out for their innovation. A new book, The Art of the Data Center, highlights these gems and provides interviews with some of the key players who produced the designs.

Real Life IT: The day the websites went out in Georgia
Google Chrome and Mozilla Firefox web browsers use the lists from the Google Safe Browsing service for checking pages against potential threats.” Internet Explorer wasn’t impacted by this problem since it uses a separate mechanism (SmartScreen filter) to notify users of malware-affected sites. The site malware was picked up by Google Safe Browsing, and then Chrome/Firefox users were presented with warnings.

Aside from a full-on Android upgrade, there's nothing like a cool new app to make your phone feel fresh and exciting again. So as we move closer to the start of spring, I thought it'd be a fine time to share some interesting new Android apps that have caught my eye. These five selections all stand out in some way -- for their excellent design, innovative functionality, or outstanding user experience. And they've all either been released or significantly updated in recent weeks.

Cloud Computing Price Comparison Engine
Use sliders to set minimum RAM, HDD, and CPU requirements for your cloud server. The result table will update accordingly with monthly prices from multiple IaaS cloud providers. You can also adjust required transfer rates and specify the maximum length of a subscription plan you are willing to prepay. Click Advanced mode for complex configuration requirements.

Optimising CPU and memory usage in AS3.0
This post is extremely useful for serious ActionScript 3.0 programmers. Kids has nothing to do with it but any serious application cant give high results and framerate without code optimization. Memory and processor optimization is especially important for those who make games and complicated graphics. Most of the information in this post represents links with description but in time maybe I will add textual information and more links.

A classic on how to run an office
Whenever the subject of management is discussed, the name of Peter F Drucker, the father of modern management, comes up.

Intel releases SSD cache acceleration software for Linux servers
Additionally, Intel's CAS now supports caching to NAND flash (solid-state drives and PCIe cards) in storage arrays. And it supports VMware vMotion, which allows virtual machines to migrate between systems while maintaining hot data on cache, regardless of the host machine. "The advantage is not just to provide better performance, but ensure no matter what happens, that performance remains consistent," said Andrew Flint, Intel's CAS product manager.

Data Clustering Using Entropy Minimization
The algorithm works with categorical and numeric data and scales well to extremely large data sets. Although all the ideas used in the clustering algorithm presented here are known, the overall algorithm and specific implementation, as claimed by the author, have not been published before. James McCaffrey call this algorithm and its implementation Entropy Minimization Iterative Agglomerate Clustering (EMIAC) to distinguish it from other clustering techniques.

Certificate Authorities form group to push for better certificate-revocation checking
The group's first efforts will focus on educating Web server administrators, software vendors, browser developers and end users about the importance of certificate-revocation checking and the benefits of adopting and implementing a mechanism called OCSP stapling -- OCSP stands for Online Certificate Status Protocol.

Need to set new rules for the “Technology Game”
Technology has a purpose. It exists in service of achieving the goals, not for its own sake or for the sake of the players. Technology should do no harm. It would be great if everyone can win, even win a little bit, but if there are losers their losses should be recoverable and not permanent. You can get back into the game. Technology should be readily available and accessible; all should have the chance to play the game.

E-stamps replace stamp papers in Delhi courts
"It's your rent agreement on the e-stamp paper. Now all stamp papers will be produced online and can be printed on normal paper like this one," explained the notary. That is true.
