‘ns‘ is a discrete event simulator targeted at networking research. Ns provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless (local and satellite) networks. ns-2 is a packet-level simulator and essentially a centric discrete event scheduler to schedule the events such as packet and timer expiration. Centric event scheduler cannot accurately emulate “events handled at the same time” in real world, that is, events are handled one by one. However, this is not a serious problem in most network simulations, because the events here are often transitory. Beyond the event scheduler, ns-2 implements a variety of network components and protocols.

Another Twitter Client I was just checking and this one is really awesome (you heard me).Hotot as the name goes is gonna be really hot pretty soon that I predict . Amazing well built this Twitter client almost all the features a user intends to use in its sleek interface.It will be pretty early to judge since its not officially available at its official site Hotot.org but I’m already in love with it. While I’m to figure out how it got the name Hotot you can go ahead and install it.
The recent built was stable enough for daily use and I’ve not experienced any errors whatsoever till now.Impressions were alike using a Twitter app on a Touch device though I really hope they get better sounds for notification .Rest at every level I see Hotot a real winner .Here are few features you really wanna know about
- supports Ubuntu Indicator Applet Notifications with sound
- supports single click Retweet feature
- supports extension support for additional features like Translation,Image Upload,Video Preview,URL Shortener & much more.
- supports Threaded view of Tweet conversations

Tor: Anonymity Online in Ubuntu
08
Nov
As we all know, Ubuntu is one of the most stable and secure operating system around. We accept the fact that it is totally free from viruses/malware but still there are some things which need to be looked upon while using Ubuntu on a Public Network like CyberCafe’s, Offices, School/College Wifi etc. Most of the times, these places are governed by Surveillance personnel compromising your privacy and freedom of browsing. To solve this problem, we have for you Tor: The Onion Router.
Tor is free software and an open network that helps you defend against network surveillance that threatens personal freedom & privacy, confidential business activities and relationships, and state security known as traffic analysis. Tor is a network of virtual tunnels that allows people to improve their privacy and security on the World wide web. Tor provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. With Tor, you will be free to browse anonymously without your ISP knowing what sites you are visiting. It can also help you bypass any blocks put up by your ISP on some particular websites as well.
How it Works :-
Tor protects a user by bouncing the communications around a distributed network of relays, it prevents somebody(may be Authorized personnel in case) watching a user’s Internet activity from learning sites being visited, and it prevents the sites from learning user’s physical location. The original IP is masked by passing it through special(Onion) routers, and hence it prevents Internet applications that are configured to send their traffic from compromising user’s privacy. Tor works with many existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol.
Tor anonymizes the origin of your traffic, and it encrypts everything between you and the Tor network and everything inside the Tor network, but it can’t encrypt your traffic between the Tor network and its final destination.
