first_img Sony PlayStation Network hacked again by resetting user passwords Hackers tried to get the best of Hotmail by figuring out how to reset Hotmail user passwords for e-mail accounts this month. Locking hotmail users out of their own accounts when trying to key in their passwords was something like a bad-dream scenario, trying to open your front door only to find your key does not work and thieves are inside. This could have turned into a big-time nightmare if Microsoft, after being notified of the weakness, had not rushed out a patch for its troubled password reset system. The Redmond company reportedly closed the loophole, so that hackers trying to manipulate data would now get an error message.

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. The fix was issued after information about the bug was actively publicized online. According to security watching reports, information about the bug and how to pull the password caper off spread “like wildfire” and some mischief-makers were offering to hack Hotmail accounts for twenty dollars a shot. They realized it was possible to manipulate data passed between a user and Hotmail servers in such a way that could give them control over an account, The flaw in the password reset functionality allowed a remote attacker to reset the Hotmail/MSN password with the attacker’s own values, according to a notice dated April 26 by Vulnerability Lab senior researcher Benjamin Kunz Mejri. The bug basically involved the way Hotmail handled (or didn’t) the information that must be processed when a user wants to reset the Hotmail password. Peter Bright, writing in ars technica, explained that Hotmail’s password reset system uses a token system to ensure that only the account holder can reset the password. The weakness was in the validation of the tokens, a weakness allowing attackers to reset passwords of any account.Vulnerability Lab researcher Mejri explained, “The token protection only checks if a value is empty then blocks or closes the web session. A remote attacker can, for example bypass the token protection with values “+++)-“. Successful exploitation results in unauthorized MSN or Hotmail account access. An attacker can decode CAPTCHA & send automated values over the MSN Live Hotmail module.”Email user stats are not uniform; the numbers set forth of Hotmail users vary, somewhere between an estimated 350 million and 360 million. Sophos and other security sites say it is not known how many of these users experienced incidents over their Hotmail accounts. Those who may have fallen victim would have known if they found they were locked out of their Hotmail accounts. Hackers would know that particular game was over in their getting an error message upon trying to sabotage the data exchange. Microsoft, addressing the incident, confirmed the fix and said “there is no action for customers, as they are protected.”last_img read more

first_img © 2012 Phys.org Citation: Consumer product giants’ eye-trackers size up shoppers (2012, July 16) retrieved 18 August 2019 from https://phys.org/news/2012-07-consumer-product-giants-eye-trackers-size.html (Phys.org) — Consumer product giants whose supply chains, profit margins, and boardroom reports depend on how fast the paper towels, shampoo, and diapers can fly off the shelves no longer dare to rely on just focus groups or survey handouts for consumer data. Technology is supporting retailers and marketers with sophisticated ways. “Neuromarketing” has become a frequently used term to describe a shopping environment where advanced technologies s including eye tracking reveal consumer wants and shopping behavior. Explore further Dr. Stephen Sands of Sands Research, for example, has done research on consumer behavior in supermarkets using a mobile EEG technique and eye tracking in a real supermarket environment. Researchers like Sands are getting a better read on what the newer technologies can actually say about consumer behavior.Businesses use the data that eye tracking collects to make decisions on product weight, package design, and where to put the items on shelves. They cannot rely just on what shoppers report back because research indicates that shoppers may say they like a product yet their purchases tell a different story. Marketers in turn look to eye-tracking solutions as helpful tools for better understanding shopping behavior. New 3-D computer simulations of shopping experiences augmented with eye-tracking technology and brain-wave monitoring are taking the place of conventional market research, according to a report this week in The Wall Street Journal. Eye-tracking collects eye data points when people are looking around a store. Eye tracking is also used to tell how the floor plan and design of the store are affecting the consumer. According to the WSJ, three company giants, Unilever, Procter & Gamble, and Kimberly-Clark, are combining three-dimensional computer simulations of product designs and store layouts with eye-tracking technology.Kimberly-Clark’s researchers in the past have used computer screens outfitted with retina-tracking cameras when testing packaging for paper towels. Their goal was to find which designs got noticed in the first ten seconds a shopper looked at a shelf. They also wanted to know if the preferences held up on different count packages, from single rolls to multipacks.Types of eye-tracking equipment may range from a special camera that is embedded in the rim of a computer screen to free-standing devices. Prices may run as high as $25,000 to $40,000, depending on the type of system. Data visualization results may be in the form of heat maps, the most familiar kind, where collected information forms a heat map that uses color to show where people looked. Another data visualization format is the Gaze Plot which shows a diagram overlaying an image of the ad or product package. Gaze Plots display the order that someone looked at a point, how long they looked at the point in relation to other points, and the path that person’s eyes took. The Gaze Plot is considered useful to learn what drew the attention of the customer, if the message was easy to interpret, and if the customer became confused at any point.

first_img More information: Law of Urination: all mammals empty their bladders over the same duration, arXiv:1310.3737 [physics.flu-dyn] arxiv.org/abs/1310.3737AbstractThe urinary system evolved to eject fluids from the body quickly and efficiently. Despite a long history of successful urology treatments in humans and animals, the physics of urination has received comparatively little attention. In this combined experimental and theoretical investigation, we elucidate the hydrodynamics of urination across five orders of magnitude in animal mass, from mice to elephants. Using high-speed fluid dynamics videos and flow-rate measurement at Zoo Atlanta, we discover the “Law of Urination”, which states animals empty their bladders over nearly constant duration of average 21 seconds (standard deviation 13 seconds), despite a difference in bladder volume from 100 mL to 100 L. This feat is made possible by the increasing urethra length of large animals which amplifies gravitational force and flow rate. We also demonstrate the challenges faced by the urinary system for rodents and other small mammals for which urine flow is limited to single drops. Our findings reveal the urethra evolved as a flow-enhancing device, enabling the urinary system to be scaled up without compromising its function. This study may help in the diagnosis of urinary problems in animals and in inspiring the design of scalable hydrodynamic systems based on those in nature.

Credit: puppy-training-solutions Journal information: arXiv (Phys.org) —Researchers at the Georgia Institute of Technology have discovered that mammals above a certain size appear to conform to what they have dubbed, the “law of urination”—that is, mammals of all sizes, they report, take approximately 21 seconds to void their bladder. Not content to use existing data, the research team undertook field work—visiting zoos and other places where animals reside—where they filmed the animals urinating (or medically speaking—engaging in micturition). They have written a paper describing their adventures and results and have posted it on the preprint server, arXiv, for those that wish to review their work.center_img © 2013 Phys.org The study, led by Professor David Hu, began as a fluid mechanics puzzle: how long should it take animals of various sizes to pee?—an apparently valid question considering the differences in size of not just the animals, but the body parts they use when relieving their bladder. The team notes that there are two main parts involved: the bladder and the urethra—the straw-like tube that carries urine from the bladder to the outside world. They note that gravity is an issue with urination mechanics—large animals, such as elephants (which can drain up to 42 gallons in one release) tend to allow gravity to do all the work. Smaller animals, such as dogs or goats use muscles to help the process along.Hu left it to his team (of undergrads) to collect field data, recording animals at various sites as they relieved themselves, hopefully, without attracting the notice of others worried they might have less than scientific notions in mind, to learn more. In studying the videos, along with others found on YouTube, the team discovered that regardless of size, all of their subjects appeared to take approximately the same amount of time to finish the job. What’s more, they discovered that the body parts used by the animals to urinate tended to have the same proportions, size-wise.Hu and his team don’t speculate as to why animals larger than bats and rats (they take just a second to urinate) take roughly the same amount of time to pee, but do note that nature seems to have made sure it wouldn’t take too long. With elephants for example, the urethra is so long that the urine speeds up as it falls, bursting out of the animal like a fire-hose. They also note that they didn’t test human beings, though they do suggest it’s likely people conform to the law of urination as well, so long as they go when their bladders are full, rather than when it’s simply convenient.

first_img The famed Karisoke Research Center was established in 1967 by Dian Fossey and has been running ever since. Its mission is to study the mountain gorilla and to assist in protecting it from extinction—a dire prediction made by Dr. Lois Leaky in the early 60’s after noting the declining population of gorillas due to poaching and loss of habitat. Today, researchers from all over the world come to the center to help study the wild gorillas and to learn from others that work there.Up until now, there have been only two reports of mountain gorillas using tools in the wide (those in captivity have demonstrated a wide range of tool use). One team of researchers spied an adult pushing a stick around in a muddy part of a river to learn whether there was anything below worth trying to catch. Another team witnessed an adult move a tree-trunk crosswise over a stream then use it as a bridge to cross over.In this latest report, team members Cyril Gruetera, Martha Robbinsa, Felix Ndagijimanab, and Tara Stoinskib report watching as a an adult female manipulated a bamboo pole to position it for use by one of her offspring, then held onto it to keep it steady as the little one clambered up the pole from the ground to join her in her perch. The team adds that it was clearly intentional as the mother didn’t act until she heard distress calls from her infant.The researchers suggest that unlike chimpanzees, which have been seen using all manner of tools in the wild to gain access to food, gorillas may be more inclined to use tools as a way to deal with the rugged environment in which they live. That suggests researchers may need to look for such use in different ways.

first_imgKolkata: Chief Minister Mamata Banerjee’s attempt to produce more doctors in the state and thereby, addressing the crisis of doctors at the state-run hospitals and medical colleges will soon take shape as the Medical Council of India is all set to increase around 450 more undergraduate medical seats in the state this academic year.After becoming the Chief Minister, Banerjee took a pledge to revamp the overall health infrastructure in the state. Many superspecialty hospitals were inaugurated by the Mamata Banerjee government and this led to the vacancies of doctors. Also Read – Heavy rain hits traffic, flightsChief Minister also said the state government was committed to create more MBBS seats. She also announced an increase in the MBBS seats in the state, which have finally got approval from the highest regulating body, the Medical Council of India. In past three years, there was no increase in the undergraduate medical seats in the state. State government has brought a significant change in health education in the state. After coming to power, Banerjee not only stressed on the development of heath infrastructure at various hospitals but also on medical education, particularly by increasing the number of medical and dental seats in the state. According to the sources, the present government has increased the combined number of MBBS and BDS seats from 2,205 to 3,750, Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedwhile the numbers of post-graduate medical seats have increased from 880 to 1,297. The numbers of post-doctoral seats have also increased to 147 from 107.The MCI has recommended the Centre for the permission of around 450 new undergraduate medical seats in the state from the current academic year. Out of the total seats, Calcutta National Medical College and Hospital (CNMCH) has bagged 50 more seats.

first_imgChildren who are born in summer are more likely to be taller and healthier adults, suggests new research.The study also revealed that girls born in summer attained puberty later —an indication of better health in adult life.More sunlight — and therefore higher vitamin D exposure — in the second trimester of pregnancy could explain the effect, the researchers said.“Our results show that birth month has a measurable effect on development and health, but more work is needed to understand the mechanisms behind this effect,” said lead author of the study John Perry from the University of Cambridge.  Also Read – ‘Playing Jojo was emotionally exhausting’The research, involving almost half a million people in Britain, looked at whether the birth month had an effect on birth weight, onset of puberty and adult height. They found that children who were born in summer were slightly heavier at birth, taller as adults and went through puberty slightly later than those born in winter months.The researchers compared the growth and development of around 450,000 men and women from the UK Biobank study, a major national health resource.The results revealed that babies born in June, July and August were heavier at birth and taller as adults. The findings were detailed in the journal Heliyon.last_img read more

first_imgSoumitra Chatterjee is a man who redefined the concept of a hero in Bengali cinema. His extraordinary talent and expressive eyes was enough to aesthetically portray a scene without dialogues. Satyajit Ray’s Apur Sansar was the turning point of his life, after which there was no looking back for Soumitra Chatterjee. As an actor, he is well known for his versatility and honesty which is evident through the characters that he has played earlier. Be it the ambitious Apu in Apur Sansar or the character of a nationalist leader Sandip in Ghare Baire or his role as Feluda in Sonar Kella, he is a man with many golden feathers to his hat. To celebrate his 81st Birthday, R.A.I.D. (group of companies) screened Satyajit Ray’s Apu in the national capital on Sunday. It is a 60-minute documentary based on Chatterjee’s life, inspiration and his overall journey, directed by Ipshita Gon Gupta. Also Read – ‘Playing Jojo was emotionally exhausting’The documentary showed the actor narrating the journey of his life from a small town to the silver screen. He repeatedly mentioned how Ray’s movies helped him to grow as an actor. He also mentioned that he could relate to the character of Apu, a small town guy who comes to Kolkata to fulfill his dreams. Ipshita, director of the documentary said:  “Satyajit Ray and Soumitra Chatterjee both complement each other. I feel that without one, the other is incomplete.” Also Read – Leslie doing new comedy special with NetflixWhen asked about the documentary, she further added: “I have been doing it (documentary) for quite some time, in bits and pieces. It took about six or seven years to complete it. Firstly it was time consuming and then I also had to deal with my finances. Also, it was necessary to coordinate with the timings of Soumitra kaku but the kind of co-operation I got from him, was awesome. “The documentary was followed by a play- Apu Trilogy, the adapted version of Ray’s Apu Trilogy. The two hour play, which was staged under the guidance of Happy Ranajit Sahoo, was beautifully portrayed. The scene which showed Apu and Durga running on the stage as Apu wishes to see a train and her elder sister, Durga takes him long with her, was interesting.last_img read more

first_imgThe magic of theatre is, in its ability to stir the penned stories, in the minds of those witnessing it. Such was the magic of Bhishmotsav, a series of skits performed as a part of the three-day event, to commemorate the birth centenary of the renowned Hindi writer- Bhisham Sahni. Director Seema Bhargava Pahwa brought forth the simplicity and depth of Sahni’s literature through the grace and poise of legendary actors like Naseeruddin Shah, Ratna Pathak Shah and Manoj Pahwa amongst other renowned artists. Based on five of his short stories, Oob, Yaadein, Dholak, Sir Ka Sadka and Samadhi Bhai Ramsingh, she took her audience through a time lapsed journey of different characters and their stories. Also Read – ‘Playing Jojo was emotionally exhausting’Staged at Epicentre Gurgaon, the 145-minute long performance where five individual stories were performed in a narrative style with one actor performing numerous characters, the act was loved by the audience. “Absolutely mind-blowing, it was an enriching experience and I am so glad to witness it. Naseer Sir’s last performance was my favorite and I loved the way he transcended into such diverse characters with ease and grace,” said Suman who has been a part of Delhi’s theatre circuit. Her husband, who himself is a theatre enthusiast added, “For me the star of the show was Ratna Pathak Shah and the way she convincingly played an old woman.” Also Read – Leslie doing new comedy special with NetflixDealing with diverse subjects, Seema chose these five stories because of their ability to transcend the era they were penned in, “They are still relevant, and I have been reading Sahni’s works ever since I was a kid and I felt the need to revive his works” said Seema. The stories had contemporary themes such as a teacher’s boredom in an examination hall in Oob; a woman and her sacrifices in Sir Ka Sadka; an educated young man dismissing customs but accepting them when an outsider appreciates the same customs in Dholak; the sound of the times bygone and the memories that lighten up a corner, when two old friends meet in Yaadein and the hypocrisy of a society in Samadhi Bhai Ramsingh. Underlying each theme was a deep understanding of human nature and the complexities that entangles our society. The fragile nature of human psyche which makes a thin line between good and evil even thinner and the way a mob mentality works, was portrayed flawlessly. An unpleasant incident occurred in the afternoon show where an audience member misbehaved with Naseeruddin Shah, making him stall his performance. When Shah asked him not to take pictures, he got into an altercation with him. Shah said: “People should know how to respect theatre as it is very distracting for an artist who is giving his 100 per cent to keep the audience engaged. Though I have been into such situations before, this person was particularly rude and I wanted to give him a piece of my mind, but I couldn’t find him.”last_img read more
