I hosted drupal during learning drupal and now partially completed module is tested on server. The server blocks many permissions which makes some features which works well on localhost fails on server ..

Errors On Changing Picture:

To make the module works well on server I tried changing picture via default method My Accounts > Edit and encountered this.
I noticed file upload error and checked the file system.
Drupal Error  (1)
No database entry is made. No file is uploaded.

Errors On File System:

Drupal Error  (2)

Steps taken:
– ‘files’ directory is given write permission.
– Temporary Directory is changed from (D:/wamp/tmp) local file system to (tmp) on drupal hosted space on my account and given write permission.

Drupal Error  (3)

Now errors on file system is cleared.

Errors On Changing Picture (After Clearing File System Errors):

Drupal Error  (4)

Database entry is perfectly made.
But File is uploaded only to ‘tmp’ Temporary Directory and not to ‘sites/default/files/pictures’.

Errors On Uploading in Module I developed:

Drupal Error  (5)

I understand that server won’t give all permission to all directories and expecially have strictly no access to local directories ..

Public authorities in India are vulnerable to cyberattacks as government and corporate leaders in the country are shockingly not even aware of the dangers and sophisticated methods used by hackers, a senior UN official has said ..

“The recent hacking of Council of Indian School Certificate Examination and CBSE websites by a 20 year old student has once again demonstrated the vulnerability of public authorities in India to cyberattacks,” said Babu Lal Jain, senior adviser to the UN Office for Partnerships, said ..

“Though the attack was sans any malicious motive and caused no damage, it was to prove in the words of the perpetrator, how unsecure the sites were on which depended the fate of millions of school-leaving students trying to enter into careers of their choice,” he told PTI in an interview ..

“What to talk of taking counter measures, shockingly a majority of Government and corporate leaders in India are not even aware of the dangers and sophistication of methods employed by the hackers these days.” ..

Not only the state and military secrets coveted by the other state spying agencies as well as economic and commercial intelligence of value to business rivals, the hackers these days have no qualms in selling the information they steal to the highest bidder, including gangs engaged in credit card frauds and other criminal activities, he said ..

Besides the young techies and nerds who indulge in hacking for fun and as a challenge to break into important and tightly secured sites, crime syndicates are on the prowl to steal passwords, account details and personal information to indulge in illegal money transfers, ATM withdrawals and other damaging activities ..

With most of the critical infrastructureelectricity grids, ports, railways, airports, banking and financial services etc dependent on the Internet for efficient working, real time information and communications, the dangers of hackers in league with terrorist groups disrupting essential services and causing large scale economic and social chaos cannot be over emphasised, Jain said ..

After loading a standard anti-virus and firewall software, most of the authorities and corporate entities in India feel that they have secured their systems and network cyber intrusions ..

A New Wooden Battery

Posted: June 24, 2013 in Tech Updates

In an era where it is cool to be environmentally aware, scientists at the University of Maryland have come up with a formula for batteries that can be counted as cool. These batteries have wood as a major element in their formation, besides fiber and sodium, making them sodium powered batteries. Sodium-ion batteries are, incidentally considered less powerful and efficient than their lithium-ion counterparts. That doesn’t however mean that these batteries can’t be useful ..

According to the team of these scientists, these wooden batteries might not end up within your smartphone or your laptop or in any other fancy gadget, but they are extremely useful for storing power on a large scale basis, given the fact that they are good for storing electrolytes as they can swell and contract many times over ..

The side effect of the process, which will lead to erosion in battery capacity is the fact that the wood wrinkles due to the stress involved, but this doesn’t stop the battery from working, In fact, according to the claims of these scientists, the batteries can be charged and recharged over 400 cycles and have a capacity of 339 mAh/g. This will only increase as the scientists better the design ..

Large scale production, however, is still some way off as what has been revealed is a working prototype at best. The discovery, however, does bode well for the future given the fact that, this is, in essence a low cost, environmentally friendly battery tech ..

“The inspiration behind the idea comes from the trees. Wood fibers that make up a tree once held mineral-rich water, and so are ideal for storing liquid electrolytes, making them not only the base but an active part of the battery,” says Hu, an assistant professor of materials science, at the University ..

Humans may be able to upload their brains to computers by as early as 2045, some futurists believe. This notion formed the basis for the Global Future 2045 International Congress, a futuristic conference held in New York, last week ..

The conference, which is the brainchild of Russian multimillionaire Dmitry Itskov, featured Ray Kurzweil – an inventor, futurist and now director of engineering at Google – who predicted that by 2045, technology will have surpassed human brainpower to create a kind of superintelligence an event known as the singularity ..

Other scientists have said that robots will overtake humans by 2100, ‘LiveScience’ reported ..

According to Moore’s law, computing power doubles approximately every two years. Several technologies are undergoing similar exponential advances, genetic sequencing to 3D printing, Kurzweil told conference attendees ..

By 2045, “based on conservative estimates of the amount of computation you need to functionally simulate a human brain, we’ll be able to expand the scope of our intelligence a billion-fold,” Kurzweil said ..

Substantial achievements have already been made in the field of brain-computer interfaces, or BCIs (also called brain-machine interfaces) ..

Jose Carmena and Michel Maharbiz, electrical engineers at the University of California, Berkeley, are working to develop state-of-the-art motor BCIs ..

These devices consist of pill-size electrode arrays that record neural signals the brain’s motor areas, which are then decoded by a computer and used to control a computer cursor or prosthetic limb (such as a robotic arm) ..

Theodore Berger, a neural engineer at the University of Southern California in Los Angeles, is taking BCIs to a new level by developing a memory prosthesis. Berger aims to replace part of the brain’s hippocampus, the region that converts short-term memories into long-term ones, with a BCI ..

The device records the electrical activity that encodes a simple short-term memory (such as pushing a button) and converts it to a digital signal. That signal is passed into a computerit is mathematically transformed and then fed back into the brain,it gets sealed in as a long-term memory ..

Martine Rothblatt – a lawyer, author and entrepreneur, and CEO of biotech company United Therapeutics Corp introduced the concept of “mindclones” – digital versions of humans that can live forever – in the conference ..

She described how the mind clones are created a “mindfile,” a sort of online repository of our personalities, which she argued humans already have (in the form of Facebook, for example). This mindfile would be run on ‘mindware’, a kind of software for consciousness ..

Big Data will grow past its hype towards 2016 to become “just data” once the technologies mature, and organizations learn how to deal with it, according to Gartner, Inc. While data is regularly defined by the dimensions of volume, velocity and variety, information management concerns must be much broader ..

“The bottom line is that not all information requires a Big Data approach,” said Frank Buytendijk, research vice president at Gartner. “The new “Big Data way’ is not going to replace all other forms of information management. There is more room – and need – for experimentation in the area of ‘information of innovation,’ for instance with social media data, or by making processes more information-centric.” ..

Buytendijk said that it’s important that organizations understand that Big Data isn’t the only stream of innovation in information management. The industry is in the middle of what Gartner calls ‘The Nexus of Forces”, and it is in the combination mobile, social, cloud and information innovation where new opportunities arise ..

Mobile has undoubtedly shaken up information dissemination. Knowledge workers expect to be Read More ..

Reliance Industries’ Jio Infocomm is still around a year away from launch of telecom service on 4G technology, said promoter Mukesh Ambani on Thursday. “We have charted an ambitious plan for the next 12 months and we foresee making rapid progress over this period towards launching our services across India.” ..

The company bought airwaves in 2010 for roughly 13,000 crore, but has not launched services till date, in anticipation of a more evolved technology ecosystem. Ambani told shareholders at Reliance Industries’ 39th annual general meeting that plans to do initial launches were on course. “Let me assure that my continued optimism is based on the significant strides that we at Reliance have taken in the past year — towards engineering and testing a world-class broadband network, and in developing a suite of compelling and synergistic digital services,” he said. He did not share a timeframe for the official launch ..

Jio’s entry in the Indian telecom market is expected to drastically bring down prices for broadband services, even though a similar launch from Airtel in Kolkata and Bangalore has not shown much immediate promise ..

A 20-year-old Indian student from Cornell University hacked into the database of ICSE (Class X) and ISC (Class XII) school exam results, exposed glaring anomalies in the marking system and went on to merrily write about his exploits in an online post ..

Kolkata-born Debarghya Das, majoring in computer science, says that all he had to do was run a simple program that entered all roll numbers after defining a range to get access to all the results. “It is shocking they haven’t implemented a more secure system,” Das told TOI on phone from New York ..

After the result’s data was crunched, analysed and plotted in graphs, Das discovered an interesting incongruity in the marking system: there are 33 different scores unattained between the passing mark of 35 and the maximum of 100 by the nearly 1,50,000 who appeared for the ICSE (Class X) exam. According to Das’ findings, not a single student got the following marks: 36, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 56, 57, 59, 61, 63, 65, 67, 68, 70, 71, 73, 75, 77, 79, 81, 82, 84, 85, 87, 89, 91, 93. Similarly, in the case of ISC (Class XII exam) a set of 24 marks between 40 and 100 were found to be unattained ..

When contacted, chairperson of the CISCE (Council for the Indian School Certificate Examinations) Gerry Arathoon, refused to comment on both data security and the unattained marks. “I can’t say anything until I have had a look at things myself,” he said ..

Pranesh Prakash, policy director at the Center for Internet and Society, says one needn’t even be a techie to execute such a hack. “You don’t need real technical skills to do this. You just need to figure out the ranges and feed them in. It is an interesting revelation that the website does nothing to obfuscate the javascript for security, but one can still retrieve data without that information. Once you have the data, it requires two minutes of programming to get it in a spreadsheet,” says Prakash ..

In his post, titled “Hacking into the Indian Education System”, Das wrote that he was doing this to “demonstrate how few measures our education board takes to hide such sensitive information”. The student also told the TOI that it wasn’t possible to change any values in marks and upload fudged data again, and that he made any significant progress in this direction only about 3-4 days after the results were announced. His online post says he also has the data for CBSE class XII. Though he hasn’t yet made it public, he does admit it was harder to crack than CISCE, though not altogether difficult ..

Schooled in Kolkata, Das is currently interning at Google, working on YouTube’s captioning system. He is also working on a tongue-controlled game and has earlier been active in game and applet design. The idea to hack the results came to him following a desire to help two close friends who had recently taken the exams ..

Das, nicknamed Deedy, told ToI that he worked on the ICSE and ISC results off and on for a week, but it essentially took about 4-5 hours to get all the data.”It took me more time to write the blog post,” says Das, referring to his 19-page post with all the graphs, data and explanations that is currently online ..

For Das, there was only one other takeaway from the whole exercise. “Regardless of any tampering, it would be nice to see a transparent exam scheme. SAT (Scholastic Assessment Test) publishes everything related to the exam results every year. It is inconceivable that a national level exam board doesn’t do that,” he says ..

Tata Consultancy Services, India’s largest software services exporter, said it has raised the chief executive N Chandrasekaran’s maximum salary limit by 50% to Rs 15 lakh a month with effect from April 1, 2014, to “compensate for the additional business activities and responsibilities.” ..

Including benefits and bonuses, TCS CEO was paid around Rs 12 crore in the year to 31 March 2013. The salary bump comes at a time when TCS is easily outpacing its competition in the Indian IT outsourcing industry. Revenue in 2012-13 grew 14%, ahead of the industry growth rate of about 11% ..

TCS also expects to beat IT industry body Nasscom’s 2013-14 growth expectations of about 12-14% ..

There will be a proportionate increase in benefits related to his salary, the company said in its annual report for the year 2012-2013 ..

The company said it ask shareholders to approve Chandrasekaran’s revised compensation at its annual general body meeting, slated to be held on June 28th ..

Really the power of open source technology has actually led ‘giants’ like Apple to take a bow. Apple may not accept its defeat to Android but the world is seeing the truth. So, this time, when Tim Cook, CEO of Apple spoke, he did not talk ill of Android. Infact, he proposed something that may sound music to Android app developers ..

Cook said that Apple will not have any issues if its applications are ported to Android. He precisely said, “We have no religious issue with porting an Apple app to Android.” He responded to a question where he was asked whether iCloud should branch out to other platforms. Cook said, “If it made sense for us to do that, we would do that. You could apply that to every area of Apple.” ..

Apple’s head honcho said that he is not ‘flustered’ by the growth of Android. Cook said, “Do I look at that? Of course, I don’t have my head stuck in the sand. But for us, winning has never been about having the most.” He reiterated Apple’s theory of quality versus quantity. He said, “Arguably, we make the best PC, but we don’t make the most. We made the best music player, and we wound up making the most — but we didn’t initially.” ..

When it came to proving his supremacy in the market, Cook turned to the usage stats rather than focusing on install base. According to an Engadget report, he said, “You can look at tablet web market share in North America. Almost every study I see has the iPad in the 80s (percentage).” He also cited NetApp figures, according to which around 59 per cent of web traffic from smartphones and tablets comes from iOS devices ..

Please note that Steve Wozniak, Apple’s co-founder, has gone on records to express his fondness for Android. As reported earlier, Wozniak says that Android scores better than iPhone in certain situations like voice commands and GPS. He adds, “I have a lower success rate with Siri than I do with the voice built into the Android, and that bothers me. I’ll be saying, over and over again in my car, ‘Call the Lark Creek Steak House,’ and I can’t get it done. Then I pick up my Android, say the same thing, and it’s done. Plus I get navigation. Android is way ahead on that.” ..

Cook may not want to accept that Android is flourishing, but he surely knows that he needs to keep developers happy to make iOS flourish ..

Search engine Google is aiming to increase the number of female computer engineers in order to reduce the gender gap in the industry ..

Co-founder Larry Page in his address during the I/O conference, said that the company is focused on recruiting more women ‘forever’ so as to ensure that the company is not all male ..

In a report by CNN, Page suggested that more young girls and women need to be directed towards technology, which will undoubtedly double the rate of progress ..

Google Vice president Megan Smith said that visibility of technical women has always been the company’s priority because in the past years women representation was low at the company’s developer conference ..

The report further added that Google held a Women Techmakers social for female I/O attendees before the conference to create projects using littleBits and arts and craft supplies ..

Smith indicated that part of the problem of having less female presence in the technology sector is the poor PR because women didn’t think the field is interesting or that they too can be good at it, the report said ..
