NVIDIA claims no implication in Hydra 200 chip delay

Yesterday we reported on the news in the early previews of what Lucid Hydra is 200 chip could, in this development. Although the product is still some time away from becoming available to consumers, there are reports claim that the technology is available on the market of delayed due to interference from Santa Clara, California-based ATI. This note shows that ATI now come with an official response to these reports and point out that no effort to address the above techniques, for his part.

After the said news item, our colleagues over at Fudzilla graphics chip maker contacted for an official response to the rumors of the reported effects of delay Lucid’s multi-GPU technology. This statement came from Igor Stanek, Nvidia’s product PR manager for Central Europe, which had this to say: “We (Nvidia) welcome Lucid on the market. We believe it is the best NVIDIA SLI multi-GPU solutions, and we are working hard to expectations of gamers’ SLI solutions which give good performance. Despite the rumors are unfounded, we do not have to switch to Lucid technology. “

As in previous articles, the Lucid’s Hydra technology is designed to provide consumers with the freedom of graphics performance to enhance its system by mixing two different graphics processors from the same vendor or different vendors. One of the first implementations of this chip will be in an MSI motherboard, called the Big Bang, which was delayed due to some problems as a driver of a chip.

Clearly above the MSI motherboard is quite true and that we need to relate to the market fast enough, given that MSI marketing and R & D have invested in this forum and probably want it to be released.

Zubbles: World's First Colored Bubbles

Shimmering with all the colors of the rainbow, bubbles are a joy to children young and old. For inventor Tim Kehoe, however, creating a bubble with a single color that won’t stain when it pops has been a 15-year, $3-million obsession. Two weeks ago, the world’s first colored, non-staining bubbles, Zubbles, went on sale.

A lot of people “said that you just can’t color a bubble,” said Kehoe, “which is discouraging when that is exactly what you are trying to do.”

The use of bubbles for entertainment purposes was first recorded about 400 years ago. Today, bubbles are arguably the world’s most popular toy, with more than 200 million bottles of bubble solution sold annually.

The simple chemistry of bubbles — two layers of soap sandwiching a layer of water about a millionth of an inch thick — has foiled virtually every attempt to modify them. Bubbles that last a little longer or can be blown a little bigger have since been created, but adding color, what some toy manufactures have called the “holy grail” of toys, has remained frustratingly elusive.

Standard food coloring or dyes have no effect; they simply run down the sides of the bubble, creating a drop of color on the bottom. Other dyes can stain bubbles, but when they pop they also stain clothes, dogs and eyes, as Kehoe discovered during one accident. Other tests, including one for a bubble dye that washed out, didn’t fare much better.

“I thought a washable bubble was a great idea,” said Kehoe. “But the kids (of a large focus group) were covered head to toe in red dye. It looked like a scene from Braveheart.”
Eventually Kehoe and his colleagues found the three different classes of dyes that produce intense, vibrant and uniform colors. Originally, it took three days to produce what would eventually become Zubbles, but now it takes about 30 minutes.

Once a bubble pops, the dye fades in 15 minutes on virtually every material imaginable: concrete, leather, nylon, cotton and paint. Even easily stained material like silk remain unstained 15 minutes after a Zubble touches them.

Right now, consumers can only buy blue and pink bubbles, although Kehoe says that he can create bubbles of any color.

Kehoe won’t say which dyes he specifically uses for the colored bubbles, but in a 2005 patent application Kehoe listed chemicals such as alkyl metal sulfate and polyether.

Kehoe also lists several other uses for the colored bubbles in the patent application, including plastics, soaps, shampoo and many others.

That’s optimistic, says Cyril Isenberg, author of the The Science of Soap Films and Soap Bubbles and a professor at the University of Kent. Isenberg doesn’t think that non-staining colored bubbles will have any market value outside of a child’s toy.

Still, the children’s toy market is a huge and lucrative one, and even if colored bubbles don’t have the success of their iridescent cousins, it was time well spent to Kehoe.

“It’s a good feeling after 15 years to see colored bubbles become reality,” said Kehoe. “After eight years, you think, ‘What am I doing this for?’ but I am absolutely glad I stuck with it.”

Additional Evidence That Potato Chips Should Be Eaten Only In Moderation

From Science Daily:

ScienceDaily (Feb. 26, 2009) — A new study published in the March 2009 American Journal of Clinical Nutrition by Marek Naruszewicz and colleagues from Poland suggests that acrylamide from foods may increase the risk of heart disease. Acrylamide has been linked previously to nervous system disorders and possibly to cancer.

After ingesting large amounts of potato chips providing about 157 micrograms of acrylamide daily for four weeks, the participants had adverse changes in oxidized LDL, inflammatory markers and antioxidants that help the body eliminate acrylamide—all of which may increase the risk of heart disease.


Unlike Diamonds, Most Minerals Not Forever

From Live Science:

Diamonds may be forever, but that’s not true of most minerals. In fact, about two-thirds of the 4,300 known minerals on Earth today owe their existence to biological processes, and thus evolved fairly recently in geological terms. So says Robert M. Hazen of the Carnegie Institution in Washington, D.C., who with seven colleagues identified three phases of mineral evolution.

The first phase began more than 4.55 billion years ago, as the solar system started developing. Chemical elements came together, forming about 250 simple minerals that in turn coalesced into planets. On Earth, the second phase stretched from 4.55 billion to 2.5 billion years ago, starting with the violent collision that formed the Moon. Earth’s temperature and pressure varied wildly; plate tectonics began churning the planet’s surface; and volatiles appeared, such as water and carbon dioxide, helping to redistribute the elements. Those changes enabled the evolution of some 1,250 new minerals.


Step Made Toward Invisible Electronics

From Live Science:

Researchers have made an advance toward a long-sought goal of building “invisible electronics” and transparent displays.

The work could eventually lead to better heads-up displays for pilots or even windshield displays and cars, as well as electronic paper that could deliver all the contents of a magazine or a newspaper on one, ever-changing, portable and perhaps even disposable sheet. Another goal: wearable electronic clothing displays.

The scientists, led by Chongwu Zhou and colleagues at UCLA developed tiny, transparent electronic circuits they say are more powerful than similar devices developed in recent years.

The work was detailed in the Jan. 27 issue of ACS Nano, a monthly journal.

In the new study, Chongwu Zhou and colleagues point out that although scientists have previously developed nano-sized transparent circuits, previous versions are limited to a handful of materials that are transparent semiconductors.


Soon you can get free office applications online

By the end of next year Microsoft will launch Microsoft Office Web Applications, Internet service, which means that the Office programs Excel, Word, Powerpoint and OneNote will be available online for free.

When you are traveling without a computer, you can sit on the hotel computer and then access your documents and edit them. You will also be able to share documents, so that your colleagues, family or friends can go in and read or edit online. More people will be able to work with the same document simultaneously, for all could see, when there are changes.

Thomas Floberg, who is Product Marketing Manager for Microsoft Office said, “All the basic editing functions are included in Web applications. The only thing that should be on the computer you are using is a browser: Firefox, Safari or Internet Explorer.”

Like Office Live Workspace, the Office Web Applications will be completely ad-funded, so they to you as a consumer, is free.

Aging Brains Allow Negative Memories To Fade

From E! Science News:

It turns out there’s a scientific reason why older people tend to see the past through rose-coloured glasses. A University of Alberta medical researcher, in collaboration with colleagues at Duke University, identified brain activity that causes older adults to remember fewer negative events than their younger counterparts.

“Seniors actually use their brain differently than younger people when it comes to storing memory, especially if that memory is a negative one,” said study author Dr. Florin Dolcos, an assistant professor of psychiatry and neuroscience in the Faculty of Medicine & Dentistry.

The study, published online in December in the U.S.-based journal Psychological Science, found age-related changes in brain activity when participants with an average age of 70 where shown standardiz


Doctor's Advice: Leave the Toilet Seat Up

From Live Science:

One of the longest-running spousal debates may now be settled in favor of men and for the sake of little boys.

Leave the toilet seat up, some British doctors now say. The reason: a rising trend for heavy wooden and ornamental toilet seats to fall down onto the penises of unsuspecting (and just potty-trained) toddlers.

Dr. Joe Philip and his colleagues of Leighton Hospital, Crewe, in England detail such penis-crush injuries in the December issue of the journal BJU International. The team reports on four boys between the ages of 2 and 4 who were admitted to hospitals with injuries serious enough to require an overnight stay.


Nibipedia – Wikipedia Meets YouTube

If you have ever searched Wikipedia and thought, “there should be a video about this,” you’re not alone. Troy Peterson and his colleagues had the same idea and acted on it by creating Nibipedia. Nibipedia is the result of matching Wikipedia entries to YouTube videos. Here is how it works, search for a video and while you’re watching that video you will see links to related Wikipedia content as well as more related videos. So far most of the matching of Wikipedia entries to videos has been done by a small group of people but now Nibipedia is looking for more teachers to try out a special teachers only beta. If you’re interested in participating in the beta, please send me an email rbyrnetech at hotmail or send me a direct message on Twitter.

I was first introduced to Nibipedia about three weeks ago. I used the Nibipedia beta with four of my high school students in the week before Thanksgiving. Started out by having students watch videos related to the US Civil War and matching Wikipedia entries to the videos. My students really enjoyed being able to quickly find information related to the references made in each video.

The second time I had students try out Nibipedia I let the students explore whatever interested them. One student explored information about China while another explored information about the CERN Large Hadron Collider. The best part of using Nibipedia in the classroom on that day was watching my students explore the things that interested them and get lost in academic content in a way that they might not explore books on a library shelf.

Applications for Education
Nibipedia could be a great research resource for students. The matching of video to text can help to make difficult concepts more accessible to some students. If your students are struggling to choose a research topic that interests them, let them explore Nibipedia for a while and see if that sparks an interest.

Below is the official press release from Nibipedia.
In an attempt to harness the power of free media and the web-engaged knowledge community, two entrepreneurs from Stillwater, MN have developed a new teaching tool that allows users to annotate web videos with links to Wikipedia articles.
The new application, currently running on a web site called Nibipedia (http://www.nibipedia.com), allows viewers to enrich a video presentation by adding links to related information in the Wikipedia online encyclopedia. The links, called “nibs,” are stored in the software’s database and presented to viewers in a timeline, or “nibstream,” tied to the video. Nibipedia’s unique approach to displaying web video was born from a desire on the part of the developers to allow web users to use new social media content to share their knowledge with other webizens interested in the same material.
“We just thought, ‘How can we get more value out of something people are already doing?'” said Troy Peterson, Nibipedia’s Chief Marketing Officer. “In the case of Nibipedia, those two things are watching videos and searching articles. There’s a ton of great content on the Web, but there isn’t an easy way to make them work together. We saw a need for a mashup of Youtube and Wikipedia. Our tool allows a person viewing a video to learn more by about the material being presented by opening a link to a Wikipedia article deemed relevant by another user. The application also recommends additional videos related to the one being viewed.”

The Nibipedia database contains metadata and links to more than 1000 educational videos and users have added more than 4000 nibs to related Wikipedia material. In an effort to keep the linking tool useful and relevant, the development team is taking a measured approach to building the content repository.

“We started small until our community develops,” said Peterson, “but there is no real limit to the number of videos we can offer. In the meantime, the more Nibipedia is used, the better it gets at making recommendations to information that will excite a specific user. Everyone learns faster when we’re given information we’re interested in, Nibipedia does this automatically.”

“Calls come in everyday from users wanting more material on Nibipedia,” said Terry Schubring, Director of Technology Development. “Content quality is key for us. Currently, only educators and other select ‘content curators’ can add You Tube videos to the available video channels. The linked Wikipedia content is constantly vetted by web users because those articles are already monitored by the Wikipedia community. We hope to use a ‘go slow’ approach to make sure the material on the site is top-shelf.”

The launch of the Nibipedia tool has focused on building a tool users could interact with intuitively. Although the video viewing interface is fairly standard and understandable to even novice users, care was taken in the design of the ‘nibbing’ functionality.

“We worked really hard to make it easy to use. If people have to learn how to do something new, they won’t do it even if it saves the world,” according to Peterson. “When the people in our Beta group said they were actually having fun and wanted to nibi more, we knew we had something here.”

The Nibipedia application is currently being used by a number of teachers in their classrooms as a way to add depth to the video content they are already using. The teacher test group is also finding that Nibipedia engages students by challenging them to add their own contribution to the presentation.

“One of my students sat down and just went nuts adding nibs” said Richard Byrne, teacher and noted educational tech blogger from Free Tech for Teachers. (http://freetech4teachers.blogspot.com/) “One student went from exploring Stephen Hawking videos to the CERN collider. Another student was exploring light bulbs and then went on to explore China. The third student is exploring a talk about Ben Franklin and has nibbed a few things.”

“The technology isn’t really even the good story here,” according to Schubring. “It’s about making it easy for people to learn and help each other. That’s why it’s so sticky. There’s an abundance of free content in the Web 2.0 world just waiting for people to make the connections. Hopefully Nibipedia is just the beginning of that.”
