Introduction: According to its site , Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. Basically, it is a server side software system that can be used to design and write scalable Internet applications. It can be used to create a web server on its own, thus removing the need of using a web server software like Apache. Due to the asynchronous I/O mode, there is minimum overhead(computation time). I have a machine running Ubuntu 12.10, so I normally use my package manager (apt-get) to install applications which are present in the repository. However, even though I did apt-get multiple times, the installed version seemed to an outdated v0.6.* where-as, the latest version as per their site was v0.10.4 (Huhhh!!!) Detailed Steps: Below are the steps which I had to perform, to get the latest nodejs up and running: ...

(Updated: March 20, 2016) Around January 20, 2009, when Barack Obama took over the office of president of the United States, there was quite a lot of media attention about the fact that he had to give up his BlackBerry, because it was considered to be a security risk. This caused almost world wide media attention, but the follow-up was less accurately covered and a number of different stories were told. Here we will show that Obama actually kept his beloved BlackBerry, but only after it had been secured by special encryption software and some additional security measures.

Bush, also used a BlackBerry during the 2000 presidential campaign, but had to give it up, as well as the use of any e-mail software, upon taking office. Three days earlier, he sent out a final e-mail to 42 friends and family members to inform them that he would no longer correspond el...

Last week, North Korea said that it entered a "state of war" with neighboring South Korea. According to a report from the state-run Korean Central News Agency (KCNA) this includes a threat to "dissolve" the United States mainland too. On Friday, March 29, KCNA also released some pictures of the North Korean leader Kim Jong-un , giving a rare look at some of his communications equipment: North Korean leader Kim Jong-un presides over an urgent operation meeting at the Supreme Command in Pyongyang, March 29, 2013. (Photo: KCNA through Reuters) Quite surprisingly we see that at the right side of the table, there's an aluminum unibody iMac computer (with a corded keybord and mouse). This computer is made by the American manufacturer Apple and is an iconic capitalist lifestyle item. If this isn't a fake remake, it's a bit strange that we see this computer here, because there's a full US embargo for exporting products to North Korea. Probably the iMac...
