transformed the lives of billions of people across the world, turned 30 on January 1,
2013. The computer network officially began its technological revolution when it fully
substituted previous networking systems on January 1 1983. Known as “flag day”, it
was the first time the US Department of Defence (DoD) — commissioned Arpanet
network fully switched to use of the Internet protocol suite (IPS) communications
system. Using data “packet-switching”, the new method of linking computers paved
the way for the arrival of the World Wide Web.

A computer called Titan, which is 10 times more powerful than the last lab machine,
has claimed the title of the world's most powerful supercomputer. Titan uses
microchips more usually used for video-gaming to crunch numbers for climate
studies, models of advanced materials and alternatives to petrol. The machine has
seized the top spot in the Top500 – a closely-watched global league of the fastest
supercomputers. Built by Cray at the US government's Oak Ridge National
Laboratory in Tennessee, Titan is 10 times more powerful than the lab's last
supercomputer, Jaguar, which led the world as recently as 2009. Titan was
measured at 17.59 petaflops or 17.59 thousand trillion calculations per second
beating the previous record of 16.32 petaflops, held by Sequoia, a supercomputer at
Lawrence Livermore National Laboratory in California, which simulates nuclear
attacks.

[B]IBM
[C]Intel
[D]AMD
IBM
IBM scientists are reporting progress in a chip-making technology that is likely to
ensure the shrinking of the basic digital switch at the heart of modern microchips for
more than another decade. The advance is based on carbon nanotubes, exotic
molecules that have long held out promise as an alternative material to silicon from
which to create the tiny logic gates that are now used by the billions to create
microprocessors and memory chips. The IBM researchers have been able to
pattern an array of carbon nanotubes on the surface of a silicon wafer and use them
to build chips that are hybrids of silicon and carbon nanotubes with more than
10,000 working transistors

Arjun Munda, the Chief Minister of Jharkhand announced Tablet Computers for Students

Chief Minister of Jharkhand Arjun Munda on the 13th Foundation Day of the State announced tablet computers for students who will pass matriculation. The Chief Minister made this announcement to prepare students of the states against the challenges that they would face in the tough competitive world of 21st Century. 

On the eve of foundation day celebration, the Chief Minister also declared that he would be working for making all the departments of the state paperless by getting them fully computerised.

Micro Blogging Site Twitter Launched New Email sharing Feature for Tweets

Micro Blogging site Twitter on 15 November 2012 launched a new service for Email Sharing of Tweets also known by one-to-many text messaging service.

The new email service is now going to allow users to share their favorite Tweets via email. The Company is giving users the ability to share tweets beyond their list of followers on the social media site.

Now,with the help of new service you can retweet any (Twitter messages) to your Twitter followers, but sometimes if you want to share with another group, like your college roommates or your parents or a friend who isn't yet on Twitter, You can simply do it with the help of this brand new service.

Suppose if you want to email a tweet click on the “more” icon next to the reply, retweet and favourite buttons in order to email a tweet to anyone you know. As per Twitter, you can add your own comment, and it’ll send an email with your comment and the tweet together.

Mobile Twitter users already had an access to this features that to for some time. But making it available on the web only makes sense, it means that instead of two slightly different Twitter experiences, we’re that much closer to the ideal of one social network, one experience.

With this, Twitter also revealed that it is going to make available photos, videos and news sharing service on it to top of the search feed.

Also, Twitter had made an update of applications for iPhone and Android to improve search results and highlight photos, videos and news shared at the service.

Chips made of Carbon Nanotubes to replace silicon chips soon

November 14th, 2012

Researchers have developed a new technique to mass produce much tinier and faster carbon nanotubes that can replace silicon chips in computers. It could be possible to replace silicon with carbon nanotubes in manufacturing computer chips. It use would make the size of the computing components much smaller.

What are carbon nanotubes? What are the applications of carbon nanotubes?

• Carbon nanotubes are allotropes of carbon (like diamond, graphite, grapheme etc.) with a cylindrical nanostructure.
• Nanotubes have been constructed with length-to-diameter ratio of up to 132,000,000:1, considerably larger than for any other material.
• They have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology.
• In particular, owing to their extraordinary thermal conductivity and mechanical and electrical properties, carbon nanotubes find applications as additives to various structural materials. For example, nanotubes form only a tiny part of the material(s) in (primarily carbon fiber) baseball bats, golf clubs, or car components.

India on 5 July 2012 signed an agreement with Indian Institute of Technology (IIT) Madras to support its faculty and students in Cloud Computing Research.  The project costs around 50 lakh rupees. The lab will be available for cloud computing courses and doctoral candidates. The students will be able to start to work in lab from next semester.

As per Yahoo Vice-President Hari Vasudev, Indian product offering generates over 200 terabytes of data in a week. Such big data research performed at the R&D lab would likely to help Yahoo in analysing data, which is later be used to improve its various products like Yahoo Home Page, Yahoo Slides. So the agreement is helpful for yahoo as well as for IIT-Madras.

Cloud Computing is the release of computing and storage capacity as a service to different community of end-recipients. It gives services with a user data, software and computation over a network.

Recently in November 2011, Yahoo! India launched a free online video service. By this, Yahoo! video will give the real matter across various sorts like news, entertainment, lifestyle and movies.

Apple had paid 60 million dollar to Chinese computer maker Shenzhen Proview Technology on 2 July 2012 to settle legal dispute over iPad trademaker. The dispute was that Proview claimed the ownership of iPad trademark whereas Apple contradicted that it had bought the trademaker earlier.

Proview demanded 400 billion dollar to settle the dispute, but Apple had paid 60 million dollar and 55 million dollar earlier. The total amount was not given to Proview inspite of that it had settled the dispute because it has to pay debts. The settlement was signed by the Communist Party of China outside the court in between Proview and Apple. The settlement was later announced in the court. The Apple transferred the amount of 60 million dollar to the Guangdong High Court account which was requested in mediation letter.

After US, Apple’s biggest market is in China. After the settlement, Apple is free to sell the new iPad 3 in China.  Apple Tablets are already approved by China telecommunications equipment certification agency in May 2012. Apple's products are made in China-based factories which are run by Taiwanese firm Foxconn.

the computer virus that recently attacked Saudi Arabia's
state oil company, ARAMCO?

Shamoon virus
US government agencies have alleged that Iran orchestrated the “shamoon” virus
that disabled tens of thousands of computers at Saudi Aramco, the world’s largest
oil company and struck Qatari natural gas firm RasGas as well. US said that Iran
likely launched the attack in retaliation for US-led sanctions over its nuclear program
and a cyber sabotage campaign reportedly backed by Washington. Where as
Iranian officials denied any role in recent cyberattacks.The "shamoon"virus can
spread through networked computers and ultimately wipes out files by overwriting
them.



INDIA'S FIRST COMPUTER INSTALLED IN INDIAN STATISTICAL INSTITUTE IN KOLKATTA

A generic top-level domain (gTLD) is one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. It is visible to Internet users as the suffix at the end of a domain name.

Overall, IANA currently distinguishes the following groups of top-level domains:^[1]

• infrastructure top-level domain (arpa)
• country code top-level domains (ccTLD)
• internationalized top-level domains (IDNs)
  • internationalized country code top-level domains
  • testing top-level domains
• generic top-level domains (gTLD)

The core group of generic top-level domains consists of the com, info, net, and org domains. In addition, the domainsbiz, name, and pro are also considered generic; however, these are designated as restricted, because registrations within them require proof of eligibility within the guidelines set for each.

Historically, the group of generic top-level domains included domains, created in the early development of the domain name system, that are now sponsored by designated agencies or organizations and are restricted to specific types of registrants. Thus, domains edu, gov, int, and mil are now considered sponsored top-level domains, much like the many newly created themed domain names (e.g., jobs). The entire group of domains that do not have a geographic or country designation (see country-code top-level domain) is still often referred to by the term generic TLDs.

gTLD	intended use
aero	the air transport industry.
asia	companies, organizations and individuals in the Asia-Pacific region
biz	business use
cat	Catalan language/culture
com	commercial organizations, but unrestricted
coop	cooperatives
edu	U.S. post-secondary educational establishments
gov	U.S. government entities at the federal,state, and local levels

The super cluster — a set of tightly-connected computers that work together — at IIT-Madras has been declared the fastest among all educational institutions in the country.

TOP500, a global project that details the most powerful known computer systems in the world, has ranked the new IBM Virgo Super Cluster at IIT-Madras as the 224th in the top 500.

The other Indian entries ahead of the one at IIT Madras are the machines at an ISRO facility in Mumbai and the CSIR Lab in Bangalore. The cluster worth Rs. 9 crore, which will be put to use from Monday, will enormously increase the speed of computing and accuracy of results of research experiments.

This new system will be available to users, both professors and research scholars, across departments. Users can access it from wherever they are.

Five years ago, the institute was the first IIT to set up a cluster with a computing power of 20 teraflops, but Virgo has a computing power of 97 teraflops.

FLAME

Iran reported substantial damage and huge data lost due to malicious software dubbed as Flame. It could be 3rd most powerful virus after  Stuxnet and Duqu viruses. Largest number of infected machines is in Iran, followed by the Israel/Palestine, then Sudan and Syria.

What is Flame?

Flame is a complex data stealing Virus that contains about 20 times as much code as Stuxnet about and about 100 times as much code as a typical virus designed to steal financial information.

What is the potential of Flame?

Flame is capable of:

gathering data files

remotely change settings on computers

turn on PC microphones to record conversations

take screen shots

log instant messaging chats

Thus it can steal sophisticated data from computers by exploiting flaws in the Windows O/S.

What are Stuxnet and Duqu?

Stuxnet: A computer worm. Basically spies on and subverts industrial

systems. It is notorious for attacking and damaging centrifuges of an Iranian uranium enrichment facility in 2010.

Duqu: Also a computer worm which is often related to the Stuxnet. It was named “Duqu” as it gives prefix "~DQ" to the names of files it creates.

To understand the potential of FLAME more, lets see the 5 Dimensions of FLAME:-

1. Complexity

2. Breadth

3. Network

4. Victims

5. Perpetrator

Complexity:

One of the most complicated pieces of malicious software ever discovered. Nearly 20 times as much code than Stuxnet.

Built with some 20 modules which even the researchers can’t fully

understand.

Breadth:

Most complete data-stealing tools found to date.

Can record sounds, access Bluetooth communications, capture regular

screenshot images and log Internet Messaging conversations.

Network:

A network of over 80 servers across the world used by the FLAME creators to

remotely access infected machines.

Can change settings on PC

Can quietly gather the stolen data

Largest such Command and Control network identified to date.

Victims:

Most number of infected infected systems found in Iran, followed by Israel and the Palestinian territories.

Also found in Sudan, Syria, Lebanon, Saudi Arabia and Egypt.

Estimated 1,000-5,000 machines infected worldwide.

Perpetrator:

Kaspersky Lab, which claimed credit for uncovering Flame, believes the virus may be the work of the same nation or nations that built the Stuxnet worm that attacked Iran's nuclear program in 2010. But the Kaspersky researchers declined to say which nation or nations they believe are behind Flame.

Why the needle of suspicion points towards the same nation states that build Stuxnet?

Actually, the creators of Stuxnet and Flame employed similar techniques to infect computers, which suggests that they were "parallel" projects backed by the same nation state.
