Latest Technologies: XMPP - Extensible Messaging and Presence Protocol

India Latest Technology - NANO

The much awaited Tata small car, which is giving sleepless nights to its rivals, was finally unveiled at the Auto Expo 2008. The small car, which is priced at Rs100, 000 (2,500 dollars), has been named Nano. According to the Tata Motors, the Nano will hit the Indian roads later this year. Ever since the Tatas announced their intention of developing the 1 lakh car (touted as people’s car), the auto industry experts have been raising doubts over the price, features, safety and specifications of Tata Nano. Have a look at specifications and other aspects of the Tata Nano, the four door mini-hatchback.

Looks & Dimensions of Nano: Keeping in mind the young age group, the Tata Motors has strived well to give the Nano a contemporary and stylish look. The snub-nosed small car derives inspiration from Fiat 500 and Nissan Micra. As far as dimensions of the car are concerned, Nano is 3.1 metres (10.23 feet) long, 1.5 metres wide and 1.6 metres high and can accommodate four to five people.

Engine: The small car sports a two cylinder 623 cc, 33 horsepower rear mounted multi-point fuel injection (MPFi) petrol engine. Tata claims that the car can touch the top speed of 105 kms.

Fuel Efficiency: Engineers at Tata Motors have designed an efficient engine that can run 20 Kms on every litre of petrol.

Pollution: Against the criticism and concerns of the environmentalists, Nano surpasses Indian regulatory requirements and Euro IV emission norms. In fact, Tata claims that the small car is less polluting than most of the bikes on Indian roads.

Safety: Tata says that they have tested the small car extensively for front, rear and side collisions and come out with a product that exceeds current regulatory requirements. The safety features of the Nano include a strong passenger compartment, intrusion resistant doors, seat belts, sturdy seats and anchorage.
Price: The base model of the car will sport a price tag of Rs 100,000 (2,500 dollars) which excludes taxes and transport costs. The high end/deluxe models will include air-conditioning and other features to be incorporated based on suggestions of the common people

XMPP - Extensible Messaging and Presence Protocol

XMPP (Extensible Messaging and Presence Protocol) is a protocol based on Extensible Markup Language (XML) and intended for instant messaging (IM) and online presence detection. It functions between or among servers, and facilitates near-real-time operation. The protocol may eventually allow Internet users to send instant messages to anyone else on the Internet, regardless of differences in operating systems and browsers.
XMPP is sometimes called the Jabber protocol, but this is a technical misnomer. Jabber, an IM application similar to ICQ (I Seek You) and others, is based on XMPP, but there are many applications besides Jabber that are supported by XMPP. The IEEE XMPP working group, a consortium of engineers and programmers, is adapting XMPP for use as an Internet Engineering Task Force (IETF) technology. In addition, the Messaging and Presence Interoperability Consortium (MPIC) is considering XMPP as an important interoperability technology. Eventually, XMPP is expected to support IM applications with authentication, access control, a high measure of privacy, hop-by-hop encryption, end-to-end encryption, and compatibility with other protocols.
IBM and Microsoft are working on a similar standard called SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE) based on Session Initiation Protocol (SIP).

XMPP Standards Foundation
The XMPP Standards Foundation (formerly the Jabber Software Foundation) is an independent, nonprofit organization whose primary mission is to define open protocols for presence, instant messaging, and real-time communication and collaboration on top of the IETF's Extensible Messaging and Presence Protocol (XMPP). The XSF also provides information and infrastructure to the worldwide community of Jabber/XMPP developers, service providers, and end users. Although our elected members and self-selected sponsors provide a legal and financial basis for the organization, the XSF not a closed industry consortium but instead is a completely open and transparent standards development organization in which any interested individual may freely participate. Furthermore, our developer-friendly standards process avoids design by committee and places a premium on the values that built the Internet in the first place: rough consensus and running code
