Cloud Computing: It’s Always Sunny in the Cloud

Cloud computing puts your desktop wherever you want it
Just 18 years ago the Internet was in its infancy, a mere playground for tech-savvy frontiersmen who knew how to search a directory and FTP a file. Then in 1993 it hit puberty, when the Web’s graphical browsers and clickable hyperlinks began to attract a wider audience. Finally, in the 2000s, it came of age, with blogs, tweets, and social networking dizzying billions of ever more naive users with relentless waves of information, entertainment, and gossip.

Multicore CPUs: Processor Proliferation

December 13th, 2011 No comments
From multicore to many-core to hard-to-describe-in-a-single-word core
But Kunle Olukotun, then a newly minted professor of electrical engineering at Stanford, saw that the party couldn’t go on forever. The microprocessors of the day couldn’t scale up as efficiently as you’d expect through the mere addition of ever more and ever faster transistors, the two things that Moore’s Law provided

A Cloud You Can Trust

How to ensure that cloud computing’s problems—data breaches, leaks, service outages—don’t obscure its virtues
More and more companies are doing just that. That’s why, according to analysts at the technology-research firm Gartner, by next year 20 percent of all businesses will no longer own their own servers. That percentage is likely to grow in the coming years. In short, cloud computing is here to stay.
