JNTUK 4-1 CSE II MID ONLINE BITS

Fight against ragging goes online

The UGC has launched a web portal to facilitate the lodging of complaints against ragging. G. Krishnakumar says the portal also acts as a central database as students are required to file an anti-ragging affidavit.

The University Grants Commission (UGC) has stepped up its efforts to weed out the menace of ragging from campuses across the country.

Alarmed by the increasing incidence of ragging, the Supreme Court passed a judgment in 2009 issuing guidelines for setting up a central crisis hotline and anti-ragging database.

Based on those directives, the UGC has developed the web portal 

The portal, launched by Union Minister for Human Resource Development Kapil Sibal on July 26, provides students an online platform to register their complaints against the barbarism of the campus kind.

Affidavit

UGC Acting Chairman Ved Prakash told The Hindu-EducationPlus over the phone from New Delhi that it was mandatory for every student and his or her parents to submit an anti-ragging affidavit at the time of first admission and thereafter each year at the time of annual registration.

The authorities had received 50 complaints online when this report was filed. There were 42 pending cases, while action was taken on eight cases. Nearly 700 anti-ragging affidavits were uploaded on the site.

Prof. Prakash said the affidavits would be stored electronically and would contain the details of each student. “The portal has information on anti-ragging regulations and directives issued by the Supreme Court. It has facilities to lodge a complaint against ragging,” he said.

The aim of the portal is to eliminate ragging in all its forms from universities, deemed universities and other higher education institutions in the country.

This will be achieved by preventing its occurrence and punishing those who indulge in ragging, in accordance with the Supreme Court regulations.

Status

Prof. Prakash said the complainants could keep track of the status of their applications and follow-up action would be taken based on the nature of the complaints. These would be passed on to the head of the institution, besides the local administration and the Superintendent of Police or the Sub-Divisional Magistrate.

Explaining that the registration of affidavits online was an easy task, UGC authorities pointed out that the complainants need to log on to www.antiragging.in. or www.amanmovement.org. They had to click on the link “Online affidavits.” Step two was to fill information as desired and submit the form. On successful completion, petitioners would receive copies of the affidavits, both for students and parents, through e-mail.

Parents need not worry if they do not have an e-mail address or phone number. They can give the e-mail id or other contact details of friends or relatives.

Complainants can start afresh and submit the information again, if they make mistakes while submitting the form.

Electronic storage

The apex court has ordered that contact details of students must be collected from these affidavits and stored electronically in a central location.

Earlier, the colleges used to collect the information but it was not stored in any central location.

An online procedure for downloading anti-ragging affidavits has been developed as part of the ragging prevention programme.

College authorities need not collect information separately and compile it from now onwards thanks to the new facility. The objective of the initiative is to save time while lodging a complaint against ragging.

Students can also call any time on the toll-free number 1800 180 5522 or send an e-mail tohelpline@antiragging.in as part of the ragging prevention programme. The college administration will extend help to the students besides the local police and the local administration.

The UGC says anybody can register a complaint of ragging of a student.

It need not be the victim alone who should lodge the complaint.

The commission has pointed out that it is the duty of every individual who comes across an incident of ragging to inform the call centre.

It will be difficult for the authorities to take action, if the person wants to protect his identity. Students can always log on to www.antiragging.in or www.amanmovement.org to track the progress of their complaint.

Google launches free SMS service in India

 Search giant Google has started rolling out free SMS for its free email service Gmail and paid email service Google Apps customers in India. The service allows users to send SMSes to mobile phones from chat windows. Users have to add mobile numbers of their contacts in the email address book and they are set. 

The service starts with 50 SMS credits for each user, every sent SMS costing one credit. Every reply received adds on 5 credits subject to the maximum level being 50 SMS at any given time. There is no official statement from Google on the launch of this service, however the service has gone live this evening in the chat windows of many users. 

Google is rolling out the service in partnership with cellular operators, which means they would share revenue with Google out of SMSes users on their network send. It specifies a way to buy more SMS credits. 

"You can always send an SMS to your own phone, and then reply to that message multiple times. Every time you send a reply message, your SMS credit is increased by five. Effectively, you're buying more messages by paying your phone company for these outgoing messages," it writes on its chat help portal. 

The service currently supports eight cellular operators including Aircel, Idea, Loop Mobile, MTS, Reliance, Tata DoCoMo, Tata Indicom and some circles of Vodafone. BSNL, MTNL and Airtel are not supported yet. 

The SMSes sent from Gmail chat are delivered to mobile phones while replies from the mobile phone come into the chat window. For the mobile phone user, the reply is charged at local SMS rate as per her/his normal billing plan. 

If no replies are received to any of the 50 SMSs sent and the credit balance come down to zero, Google says, "...it will increase back up to one 24 hours later. So, you won't ever be locked out of the system."

General Motors plans to hire 10,000 software developers, programmers

DETROIT: Now hiring in Detroit: Software developers and programmers. General Motors is moving past layoffs and the Motor City's rusty, low-tech image. It's setting out on its own to develop software and invent the most advanced gizmos for your car. 

America's biggest automaker plans to hire up to 10,000 computer professionals in the next three-to-five years as it tries to lead the auto industry with cutting-edge technology. 

It's a bold and expensive move, counter to the industry's history of buying software and other electronic applications from outside companies. Experts say it's also the start of a trend as manufacturers realize that software is among the few things that will set them apart from competitors. 

"The companies that build the software themselves in general are going to have an advantage," says David Kirkpatrick, author of a book about Facebook and CEO of Techonomy Media, a New York firm that specializes in setting up technology conferences. "If you outsource the development of software in particular to others, you can risk ... your own ability to compete in the future.'' 

General Motors isn't alone in trying to move more technology development under its roof. But the plans of its biggest competitor, Ford Motor, aren't nearly as ambitious. 

GM's aims to bring 90 per cent of its computer technology work into the company by recruiting workers to four new information technology centers around the nation. Ford recently joined GM, BMW AG and Renault-Nissan in opening a technology office in California's Silicon Valley, although it's staffed by only about 15 people. 

GM's first "Information Technology Innovation Center" was announced last month in Austin, Texas, with plans to hire 500 programmers and software experts. And Monday the carmaker unveiled plans to hire 1,500 more at a second computer center in Warren, Michigan, on the campus of its big tech center. GM already has product designers, engineers and other technical experts at the site, including the team that created the Chevrolet Volt electric car. 

The other two sites haven't been revealed. 

Staff at the centers will try to stay on top of software trends. They'll develop the latest ways to link smartphones with cars or control a vehicle's heating and air conditioning with voice commands. They'll also be counted on to invent technology that no one's thought of yet. And GM also sees long-term cost savings when the centers are fully in operation. 
"We're currently seeking the next generation of game-changers to help us usher in a new age of automotive innovation,'' says GM Chief Information Officer Randy Mott, who was Hewlett-Packard's CIO until he joined GM in February. 

Although there are shortages of programmers and software engineers in some parts of the country, GM should be able to recruit enough talent by setting up shop in four different regions, experts say. With the tech-hub of Austin and GM's home base in Detroit already covered, the most likely locations for the next two centers are on the West Coast, experts say. 

GM says it will offer competitive wages and benefits to pull in recent college graduates and experienced information technology professionals. The company's iconic brand status will help attract people, experts say. 

But offering competitive pay will cost GM. Software engineers make $60,000 to $70,000 a year right out of college, and experienced workers can make more, says James Stoeckmann, senior compensation specialist for World at Work, an organization of human resources executives who deal with pay issues. 

Expensive or not, the strategy is correct for GM as it tries to differentiate its products from other automakers, says Michael Robinet, managing director of IHS Automotive, an industry consulting firm. With the gap in quality between brands shrinking, the way a car drives and its electronics soon will be the only things that set a company apart, he says. 

Currently, GM and most automakers rely on outside companies for touch screen and other technology. But often those companies sell the technology to multiple carmakers, or new software is sold in an expensive bidding war, Robinet says. "If they have their own skunk works and they find a new technology, they are guaranteed to bring it to market first," he says. 

Ford, for instance, worked with Microsoft Inc. on its pioneering Sync system, which brought voice activation technology into cars ahead of most competitors. But Ford only had exclusive use of the system for a year before Microsoft was able to license it to other companies, namely Hyundai and Kia. 

Outside companies have so much expertise that it will take years for GM to catch up, making it unlikely that the company will completely walk away from outside firms, Robinet says. 

Yet with software gaining so much importance in the way all companies operate, it's even possible that GM will find its next generation of leaders somewhere in the computer centers, says Kirkpatrick. "CEOs of every company in the future are going to have to be software thinkers," he says.
