But that only begins to describe Google’s ability to find information. Inside the company, engineers use several uniquely powerful tools for searching and analyzing its own massive trove of data. One of those is  Dremel , a tool that helps Google’s employees analyze data stored across thousands of machines, at unusually fast speeds. What’s more, Dremel lets the Google team to manipulate all of this data using a language very similar to SQL, short for Structured Query Language, the standard way of grabbing information from databases. Like most of its custom-built tools, Dremel is only available inside Google. But now, the rest of the world can hack data a little more like Google does, thanks to Quest, a Dremel-like query engine created by Theo Vassilakis, one of the lead developers of Dremel at Google, and Toli Lerios, a former en

JAVA-Oracle 7 in UBUNTU  If you really need to use Oracle (ex Sun) Java instead of OpenJDK in Ubuntu, here's an easy way to do it:  a PPA repository to install and keep your computer up to date with the latest Oracle Java 7 (Java JDK which includes JRE).

Please note that this package is currently in alpha and is offered without any guarantees, so it may or may not work! Use it at your own risk! The package should support proxies just like the flashplugin-installer does, but it may fail if your ISP or router blocks some non-standard ports because Oracle uses quite a few redirects for th
