Toshiba To Roll Out New SD Cards

Toshiba America Electronic Components, Inc., and its parent, Toshiba Corp., are set to launch two new series of SD cards that offer high-level data transfer rates and read-write performance. The 'high-speed series' will offer a maximum data transfer rate of 5MB per second, while the 'ultra high-speed series' will push transfer rates to as high as 20MB per second, double the rate of any other Toshiba-brand SD Cards.
Both the high-speed series Speed Class 4 SD Cards and ultra high-speed series Speed Class 6 SD Cards will be made available in 512MB(2), 1GB(3) and 2GB capacities. The SD Speed Class will be clearly stated on the card and its packaging, allowing users to select the card that makers specify for use with their digital products. Applications will include video recording with high performance digital cameras."The speed class is important to maximise performance for demanding applications and help the consumer choose the right card for their camera or camcorder," said Brian Kumagai, business development manager, NAND Flash, for TAEC.In May this year, the SD Card Association introduced the SD Speed Class, defining three minimum data transfer rates for next generation SD Cards: Class 2 supports a minimum data transfer rate of 2MB per second; Class 4 supports 4MB per second; and Class 6 6MB per second. Toshiba is first in the industry to announce the launch of Class 6 products.

BBC Planning MP3 Radio?

What Arnold Schwarzenegger has done to bodybuilding, iPod is doing to the MP3 players: making it a household name. Now, BBC is doing sometime on the lines of the two. BBC is buildng more muscles to go beyond the traditional media and enter a domain, hitherto unoccupied -- MP3 Radio.
BBC, inspired by the penetration of MP3 players, is planing to develop a device, plug-in gadget, that would convert any MP3 player into a digital radio. BBC has not disclosed if it has collaborate with certain companies for the development of the gadget, or that the service will be available on some particular devices like iPod or MP3 players of mobile phones.According to a BBC spokesman, “It's important for to us to make sure that people can listen to digital radio on their own terms."So, with BBC entering the domain, the market will sure see more players.

Yahoo! User ID, Password Could Be Stolen: Websense

Websense Security Labs has observed a change in the technique used in Yahoo! phishing attacks. These phishing attacks attempt to capture a user's Yahoo! ID and password by displaying a fake Yahoo! Sign In page. This variant of attack has been on-going for over a year. After the Yahoo! acquisition of Flickr, these attacks have started to shift from targeting Yahoo! Photos to targeting Yahoo! Flickr.
Attacker sends an email or instant message that claims to be from a friend wanting to show off photos that have been posted to Flickr. The message contains a link to a phishing site, which captures the user's Yahoo! ID and password.In September 2005, a similar Phishing attack on an alternate Yahoo Page- Yahoo Photos was detected by Websense Security Labs. Users received emails with a link to a Phishing Site which recorded the user's login details before forwarding the Yahoo! ID and password on to the real Yahoo! Photos site.

HP Develops Chip As Small As A Grain!

As tiny as a grain of rice or smaller, with a built-in antenna, the chip doesn't need a battery. It can be embedded in a sheet of paper or stuck to any surface, and could eventually be available in a booklet as self-adhesive dots.
HP has developed a miniature wireless data chip that could provide broad access to digital content in the physical world. With no equal in terms of its combination of size, memory capacity and data access speed, the tiny chip could be stuck on or embedded in almost any object and make available information and content now found mostly on electronic devices or the Internet.
The experimental chip, developed by the 'Memory Spot' research team at HP Labs, is a memory device based on CMOS (a widely used, low-power integrated circuit design) and about the size of a grain of rice or smaller (2 mm to 4 mm square). The chip incorporates a built-in antenna and is completely self-contained, with no need for a battery or external electronics. It receives power through inductive coupling from a special read-write device, which can then extract content from the memory on the chip.The chip has a 10 megabits-per-second data transfer rate -- 10 times faster than Bluetooth wireless technology and comparable to Wi-Fi speeds -- effectively giving users instant retrieval of information in audio, video, photo or document form. With a storage capacity ranging from 256 kilobits to 4 megabits in working prototypes, it could store a very short video clip, several images or dozens of pages of text. Future versions could have larger capacities.Information can be accessed by a read-write device that could be incorporated into a cell phone, PDA, camera, printer or other implement. To access information, the read-write device is positioned closely over the chip, which is then powered so that the stored data is transferred instantly to the display of the phone, camera or PDA or printed out by the printer. Users could also add information to the chip using the various devices.

Adobe Joins Google Camp

Adobe has joined the league of those who offer Google Toolbar with their products. The multi-year deal brings the two giants together, making Yahoo! little unhappy regarding the promotion of its own Yahoo! Toolbar. Microsoft, having had a spat with Adobe over the offering of PDF conversion format in its latest Office suite, may also feel some heat around the corner. Microsoft had to withdraw the option allowing users to save documents in PDF format from its Office suite following Adobe's objections. Google already has similar collaborations for Google Toolbar with companies like Mozilla for its browser Firefox. As a part of the agreement, Adobe and Google have announced the availability of the Google Toolbar with downloads of Adobe's Macromedia Shockwave Player. The Google Toolbar will now be offered as part of the Shockwave Player installation process for Internet Explorer on Windows. Under the terms of the agreement, the Google Toolbar will also be offered as part of other Adobe product installations in the future.Available for free, the Shockwave Player allows users to view interactive Web content, such as games, business presentations, entertainment and advertisements from a Web browser. Hundreds of thousands of Shockwave Players are downloaded every day, and Shockwave Player is installed on more than 55 per cent of Internet-enabled desktops.

Talk To Your iPod

'Play it again' is all you will need to say to your iPod instead of fumbling with its Clickwheel. But, is a talking iPod enough to silence Microsoft which is reportedly coming out with a rival product this Christmas? However, the new feature will certainly add more fun to using an iPod. This feature will enable users to surf for tracks and artists without looking at the screen. While Apple is mum on the talking iPod, some online newspapers report that 'a patent lodged by the company in the United States serves as proof to that.' The patent application says, "A user will have difficulty navigating the interface in 'eyes-busy' situations. Such activities include, for example, driving an automobile, exercising and crossing the street." Apple has been critised for iPod users meeting accident while operating the player during driving. The move will work two fold: as a security feature and an added entertainment

Your Pain Is Google's Gain: Google Health On Cards?

Having a mild headache, but want to know whether it's migrane or something else before going to doctor? Here is your chance, log on to Google.

Google is working on a service, to be known as Google Health Scapbook. The portal will cater to the needs of patients, doctors, vendors and pharmaceutical companies. The service will not only provide information, but also allow users keep a track of their medical records and pay medical bills online. The reports are that Google is collaborating with WebMD and Intuit for the service. Some online websites report that the project is supposedly supervised by Missy Krasner, a project manager who joined Google earlier this year.But Google is (as its trademark) silent over the reports, it says, "Health has been an area of interest at Google for some time. We have been doing a variety of research in the health area, including how to improve the quality of health-related search results. Google Co-op is one reflection of that. We continue to look for more ways to benefit our users in the area of health, but we do not have any products to announce at this time. As part of our efforts, we work with many companies in formal and informal ways."
