The internet has seen an unprecedented network growth in the recent past. But According to the standard protocol there is a limitation in the number of IPs that can be supported. This hinted at a possibility that with the increasing number of devices the internet is about to run out of IP addresses very soon. The proposed solution is about to be implemented next week.

On June 6 all major Internet service providers (ISPs), home networking equipment manufacturers, and web companies around the world are coming together to permanently enable IPv6 for their products and services. It is the Internet Protocol version 6 which will allow 2^128 address spaces that can support billions of devices to connect to internet and it will also improve the QoS (Quality of Service) parameters in services including video and audio. The list of companies to shift to IPv6 includes Facebook, Google, Yahoo, AT&T, Cisco, and Akamai to name a few.

On June 8 2011, some companies tried out the IPv6 addresses for a day. The check was done to look for any issues that may crop up when the final transition from IPv4 to the new protocol is made. Last year’s industry-wide test of IPv6 successfully showed that its global adoption is the best way to keep web devices communicating in the future.” saidJay Parikh, VP of Infrastructure Engineering at Facebook.

This change to IPv6 is not going to affect end users too much. The 4 digit IP addresses will change to 6 digit addresses and there will a large number of IP addresses available for users.

 “The Internet has grown to be an essential part of our daily lives. It connects our devices to our apps; more importantly, it connects us to each other. Yahoo! is proud to be a part of the World IPv6 Launch – an event that marks the next chapter of our Internet. IPv6 enables the Internet to grow, while remaining open and accessible to new applications and new ideas.” said Jason Fesler, Distinguished Architect and IPv6 Evangelist, Yahoo!

Launching Airtel’s 4G services in Kolkata Tuesday, Telecom Minister Kapil Sibal admitted that 3G services have not been as popular as 2G due to lack of liquidity in the market to invest in the infrastructure and the devices required.

“We will give the environment to the industry to manufacture low cost quality smart phones. But it is the industry which has to deliver. This is the biggest challenge for the industry,” he told reporters.

“3G has not delivered because they paid such huge prices for the spectrum and there is no liquidity in the market for them to invest in the infrastructure and the devices to deliver 3G, for which 2G was successful and 3G was not successful.”

He hoped that the industry would keep this in mind and “ensure that people of this country have low cost devices”.

Sibal was speaking at the launch of broadband wireless access (BWA) services based on 4G technology here.

Telecom major Bharti Airtel Tuesday became the first telecom operator to launch broadband wireless access (BWA) services based on 4G technology in the country.

The high speed service was inaugurated by Sibal.

A successor to the 3G and 2G families, 4G is expected to be five times quicker than 3G services. It would offer services such as high-definition mobile TV and video conferencing.

Asked when the 4G will be rolled out in other cities, the company’s chairman and managing director Sunil Mittal said: “We are working very fast to launch in the other circles that we have.

“Hopefully, within this month it will be launched in Bangalore, within weeks followed by Pune, and then Chandigarh.”

Airtel, which had bagged BWA spectrum in four telecom circles – Kolkata, Maharashtra, Punjab and Karnataka – for rs. 3,314.36 crore in 2010, selected Chinese telecom equipment maker ZTE to manage its services in Kolkata.

The other players are yet to announce plans to rollout 4G services.

Around 30 per cent of all internet traffic is pornography, and the biggest porn site gets over four billion page views and 350 million unique visits per month, a study has found.

The ExtremeTech website said the only other websites that surpass this figure in size are Google and Facebook, the Daily Mail reported.

The report uncovered the viewing figures for porn website Xvideos from Google’s DoubleClick Ad Planner, which uses cookies to gather information about users.

It also used actual data from the second biggest porn site, YouPorn, to check how much data is being transferred out of the website’s servers.

The average length of time spent on Xvideos was 15 minutes. Around 29 petabytes a month, or 50 gigabytes per second, of pornography is being transferred.

The YouPorn website hosts over 100TB of porn, gets 100 million page views and transfers 950 terabytes per day.

Earlier this year, over 6,400 passwords and emails of YouPorn users were hacked and details revealed online.

Sam Pitroda, advisor to Prime Minister Manmohan Singh, Wednesday launched the country’s first cloud-based tablet solution for school students called ‘e-tutor tablet’.

This can be used by students from Class 1 to 12. Priced at 7,500, inclusive of content, the product would be available in the market from April onwards. The e-tutor tablet is a joint effort of Technopark-based e-tutor and Oztern Technology.

Ranjith Balan, founder and managing director of e-tutor, said that this will be the first complete solution for education to be made available on Tablet PCs.

“The teacher can easily explain concepts using the digital whiteboard that is set up in the Tablet PC. Using e-tutor learning tablet the students can access what was taught in the classroom and can also access the collaborative learning platform for discussions on relevant topics taught in the classroom,” said Balan.

The product is also aimed at making internet a safer place for children. E-tutor tablet safeguards the connectivity from the personalized Tablets PCs provided as a part of the solution, and restrict it to connect to internet only through the synchronization module in the product.

Detailing on the technology, Saiju V. Stella, CEO of Oztern Technology, said cloud computing technology can bring about a major leap in the way technology is being used in the educational sector.

“Most of the technology products available in the market today for education act as teaching aids rather than learning aids. Cloud computing also fulfills another major social commitment by reducing the carbon emissions, from dedicated servers and data centres that consume huge amounts of energy, thus making computing more energy efficient and green,” said Stella.

Lessons will be made available to the learner through personalised Tablet PCs, and regular content updates will be made available through a unique cloud – tablet synch mechanism, thus making sure that the device connects only to the relevant locations to access content.

Rajinish Menon, director, Business Strategy and Operations, Microsoft, who was present at the occasion, expressed his happiness to see partners like Oztern coming up with innovative solutions in the education sector using Microsoft Windows Azure which is Microsoft’s cloud computing infrastructure.

Cloud computing is a technology that uses internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth.

The world of web-application development framework has a new arrival: Ruby on Rails 3.2, which is said to be quicker and more convenient for web-application developers.

The first version of the Rails framework was released in 2004 as an open-source framework that would help in the quick assembly of web pages, based on the Ruby programming language, and the framework last saw a major release in August, with the 3.1 version.

The latest version of the Rails framework has a number of improvements on the previous version the most important of which is a faster development mode as it only re-loads altered classes instead of the whole library of classes used, making a larger applications a lot faster to load.  It also has a ‘tagged logger’ feature which makes it convenient for a multi-user environment—developers can now filter the log of applications based on who run them. Database queries are tagged and explained, making debugging an activity that can be performed with ease. The new routing engine implemented by the framework, called “Journey”, moreover is a breeze to use especially since it makes linking much faster and noticeable which would be of great help especially in cases that involve numbers like a hundred different links on each page.

While JavaScript has been used by a number of websites as a result of its HTML-5 compatibility, around 226,000 websites use Ruby on Rails. Aaron Batalion, chief technology officer and cofounder of LivingSocial, which uses the framework ardently, said “We wanted to focus on the actual products we were building and less on the engineering”. “Ruby on Rails is interesting because it gets out of your way”.
