Though the corded ones were very popular they are being fast replaced by the wireless ones. Commercially speaking the wireless ones are more convenient. With the corded headphones you had to deal with many cables and connections which you had to connect to different points in the system. They were also quite cheap. The wireless ones, particularly the Bluetooth headsets are comparatively expensive yet with them you don't have to deal with cables and cords........ ]]> http://www.technology-blog.com/blogs/permalinks/2-2010/gadgets-may-not-cause-headache.html http://www.technology-blog.com/blogs/permalinks/2-2010/gadgets-may-not-cause-headache.html Fri, 12 Mar 2010 14:06:09 GMT Use of most electronic media is not linked to headaches, at least not in adolescents. A study of 1025 13-17 year olds, reported in the open access journal BMC Neurology, found no association between the use of computer games, mobile phones or television and the occurrence of headaches or migraines. However, listening to one or two hours of music every day was linked to a pounding head........ ]]> http://www.technology-blog.com/blogs/permalinks/12-2009/moving-video-to-captcha-robot-hackers.html http://www.technology-blog.com/blogs/permalinks/12-2009/moving-video-to-captcha-robot-hackers.html Fri, 12 Mar 2010 14:06:09 GMT We see the popular "captcha" security mechanism often - wavy letters websites ask us to type into a box. It's used by web pages and newsletter sign-up forms to prevent computer robots from hacking into servers and databases. But these codes, which are becoming increasingly complicated for an average person to use, are not immune to security holes........ ]]> http://www.technology-blog.com/blogs/permalinks/12-2009/do-computers-understand-art.html http://www.technology-blog.com/blogs/permalinks/12-2009/do-computers-understand-art.html Fri, 12 Mar 2010 14:06:09 GMT A team of scientists from the University of Girona and the Max Planck Institute in Gera number of has shown that some mathematical algorithms provide clues about the artistic style of a painting. The composition of colours or certain aesthetic measurements can already be quantified by a computer, but machines are still far from being able to interpret art in the way that people do........ ]]> http://www.technology-blog.com/blogs/permalinks/11-2009/smartphone-app-illuminates-power-consumption.html http://www.technology-blog.com/blogs/permalinks/11-2009/smartphone-app-illuminates-power-consumption.html Fri, 12 Mar 2010 14:06:09 GMT A new application for the Android smartphone shows users and software developers how much power their applications are consuming. PowerTutor was developed by doctoral students and professors at the University of Michigan. Battery-powered cell phones serve as hand-held computers and more these days. We run power-hungry applications while we depend on the phones to be available in emergencies........ ]]> http://www.technology-blog.com/blogs/permalinks/10-2009/how-to-get-a-cool-laptop.html http://www.technology-blog.com/blogs/permalinks/10-2009/how-to-get-a-cool-laptop.html Fri, 12 Mar 2010 14:06:09 GMT Does your laptop sometimes get so hot that it can almost be used to fry eggs? New technology may help cool it and give information technology a unique twist, says Jairo Sinova, a Texas AandM University physics professor. Sinova and his colleagues from Hitachi Cambridge Laboratory, Institute of Physics ASCR, University of Cambridge and University of Nottingham have had their research reported in the renowned journal Nature Physics........ ]]> http://www.technology-blog.com/blogs/permalinks/10-2009/better-dvd-from-mantis-shrimps-technology.html http://www.technology-blog.com/blogs/permalinks/10-2009/better-dvd-from-mantis-shrimps-technology.html Fri, 12 Mar 2010 14:06:09 GMT The remarkable eyes of a marine crustacean could inspire the next generation of DVD and CD players, as per a newly released study from the University of Bristol published recently in Nature Photonics The mantis shrimps in the study are found on the Great Barrier Reef in Australia and have the most complex vision systems known to science. They can see in twelve colours (humans see in only three) and can distinguish between different forms of polarized light........ ]]> http://www.technology-blog.com/blogs/permalinks/10-2009/use-computer-security-guide-to-protect.html http://www.technology-blog.com/blogs/permalinks/10-2009/use-computer-security-guide-to-protect.html Fri, 12 Mar 2010 14:06:09 GMT Just in time for October's Cyber Security Awareness Month, the National Institute of Standards and Technology (NIST) has published a guide to help small businesses and organizations understand how to provide basic security for their information, systems and networks. NIST has also created a video that explores the reasons small businesses need to secure their data (at right)........ ]]> http://www.technology-blog.com/blogs/permalinks/9-2009/ants-vs.-worms.html http://www.technology-blog.com/blogs/permalinks/9-2009/ants-vs.-worms.html Fri, 12 Mar 2010 14:06:09 GMT In the never-ending battle to protect computer networks from intruders, security experts are deploying a new defense modeled after one of nature's hardiest creatures - the ant. Unlike traditional security devices, which are static, these "digital ants" wander through computer networks looking for threats, such as "computer worms" - self-replicating programs designed to steal information or facilitate unauthorized use of machines. When a digital ant detects a threat, it doesn't take long for an army of ants to converge at that location, drawing the attention of human operators who step in to investigate........ ]]> http://www.technology-blog.com/blogs/permalinks/9-2009/rome-was-built-in-a-day.html http://www.technology-blog.com/blogs/permalinks/9-2009/rome-was-built-in-a-day.html Fri, 12 Mar 2010 14:06:09 GMT The ancient city of Rome was not built in a day. It took nearly a decade to build the Colosseum, and almost a century to construct St. Peter's Basilica. But now the city, including these landmarks, can be digitized in just a matter of hours. A new computer algorithm developed at the University of Washington uses hundreds of thousands of tourist photos to automatically reconstruct an entire city in about a day........ ]]> http://www.technology-blog.com/blogs/permalinks/9-2009/trash-or-treasure.html http://www.technology-blog.com/blogs/permalinks/9-2009/trash-or-treasure.html Fri, 12 Mar 2010 14:06:09 GMT More computers discarded by consumers in the United States are getting a second life in developing countries than previously believed, as per a newly released study the most comprehensive ever done on the topic reported in ACS' semi-monthly journal Environmental Science and Technology The findings may ease growing concerns about environmental pollution with toxic metals that can result from dismantling and recycling computer components in developing countries........ ]]> http://www.technology-blog.com/blogs/permalinks/7-2009/this-article-will-self-destruct.html http://www.technology-blog.com/blogs/permalinks/7-2009/this-article-will-self-destruct.html Fri, 12 Mar 2010 14:06:09 GMT Computers have made it virtually impossible to leave the past behind. College Facebook posts or pictures can resurface during a job interview. A lost cell phone can expose personal photos or text messages. A legal investigation can subpoena the entire contents of a home or work computer, uncovering incriminating, inconvenient or just embarrassing details from the past........ ]]> http://www.technology-blog.com/blogs/permalinks/6-2009/computer-related-injuries.html http://www.technology-blog.com/blogs/permalinks/6-2009/computer-related-injuries.html Fri, 12 Mar 2010 14:06:09 GMT While back pain, blurred vision and mouse-related injuries are now well-documented hazards of long-term computer use, the number of acute injuries connected to computers is rising rapidly. According to a study published in the July 2009 issue of the American Journal of Preventive Medicine, researchers from the Center for Injury Research and Policy and The Research Institute at Nationwide Children's Hospital; and The Ohio State University College of Medicine, Columbus have found a more-than-sevenfold increase in computer-related injuries due to tripping over computer equipment, head injuries due to computer monitor falls and other physical incidents........ ]]> http://www.technology-blog.com/blogs/permalinks/6-2009/sounds-of-water.html http://www.technology-blog.com/blogs/permalinks/6-2009/sounds-of-water.html Fri, 12 Mar 2010 14:06:09 GMT Splash, splatter, babble, sploosh, drip, drop, bloop and ploop! Those are some of the sounds that have been missing from computer graphic simulations of water and other fluids, as per scientists in Cornell's Department of Computer Science, who have come up with new algorithms to simulate such sounds to go with the images........ ]]>
