What's After the Real Time Web?

In typical Web-industry style we’re all focused minutely on the leading trend-of-the-year, the real-time Web. But in this obsession we have become a bit myopic. The real-time Web, or what some of us call “The Stream,” is not an end in itself, it’s a means to an end.… Read More “What's After the Real Time Web?”

The Future of the Desktop

This is an older version of this article. The most recent version is located here:


I have spent the last year really thinking about the future of the Web. But lately I have been thinking more about the future of the desktop.… Read More “The Future of the Desktop”

WiTricity Coming Soon

Another interesting article on the move towards wireless power, or what some are calling "WiTricity." I’ve written about this previously. The team at MIT is making some good headway. Check out the article for a diagram of how their wireless power beaming system works.… Read More “WiTricity Coming Soon”

Frequent Mobile Phone Use Linked to Tumor

If you or your children use cell phones frequently, consider getting earphones…

Long-term users of mobile phones are significantly
more likely to develop a certain type of brain tumour on the side of
the head where they hold their handsets, according to new research.

New Wireless Power Technology — No More Wires!

A group of physicists at MIT have come up with a new model for beaming wireless power to mobile devices, such as computers or cell phones. It promises to do for power, what wireless ethernet hubs do for network connectivity.… Read More “New Wireless Power Technology — No More Wires!”

Study: Blackberry Addiction Similar to Drugs

Blackberry email devices can be so addictive that owners may need to be
weaned off them with treatment similar to that given to drug users,
experts warned today.

They said the palmtop gadgets, which have been nicknamed
‘crackberries’ because users quickly become hooked on them, could be
seriously damaging to mental health.… Read More “Study: Blackberry Addiction Similar to Drugs”

Location Awareness — The Next Big Thing

Japanese cell phone company KDDI is offering a new GPS-enabled 3D navigational tool to their 17 million subscribers (see article and picture). Their system helps consumers navigate city streets and even within buildings, using an innovative 3D map and audio directions.… Read More “Location Awareness — The Next Big Thing”

New Low Power Broadband Wireless Networking Technology May Spark Revolutionary Advance

This article just came in (via Kurzweil)

A little-known start-up has demonstrated wireless broadband 1000
times more efficient than WiMax – and claims the technique could also
make wireless LANs that will run for years on watch batteries.

Technology, based in Sarasota, Florida, used a transmitter not unlike a
cordless phone base station, operating in the unlicensed – and crowded
– 900MHz band, to send a 3.7Mbit/s data signal to a radius of 18 miles
across the suburbs of Miami, using 50mW and an omnidirectional antenna.

Silent Speech Technology

NASA’s research on subvocalization technology is moving forward. Their system intercepts nerve signals to the vocal cords before the speaker makes a sound and then figures out what words they signify. This technology will enable people to speak silently on the phone or to their computers, without moving their lips or making a sound.… Read More “Silent Speech Technology”

Scale-Free Networks and Mobile Services

Here is an interesting article about an analysis of SMS messaging versus e-mail messaging on mobile networks. The conclusion is that e-mail messaging is more efficient for mobile consumers because email networks are scale-free networks. The article predicts that services based on scale-free topologies will ultimately win out over less optimal alternatives.… Read More “Scale-Free Networks and Mobile Services”

New Way to Extend Mobile Device Battery Life

HP researchers have devised a new way to save power on mobile devices by only activating the part of a device’s display that the user is actually looking at.

Cell Phones Become Credit Cards

It’s finally happening in the USA — your cell phone is about to morph into a credit card, and soon will evolve into your digital wallet. Read more.

Near Field Communication

NFC. An interesting way for devices to share data, if they are within a few centimeters of one another. Sounds kind of like Bluetooth — which I have still not needed for anything. But I like the vision anyway — if all devices did this it could be very useful — I’ve always wanted to be able to “grab” data by swiping my phone near something I am interested in (without needing a bar code scanner).… Read More “Near Field Communication”

Storing Data In the Human Body

Following up on my earlier post about storing messages in DNA it might be interesting to explore ways to encode large volumes of data directly into parts of the human body. Messing with DNA is risky — it may be safer to store data in other parts of the human body (with the one potential disadvantage that such data would not be passed down via heredity).… Read More “Storing Data In the Human Body”

Microsoft Patents using Human Body to Transmit Power and Data

Check out Microsoft’s new patent for transmitting power and data through the human body. Good idea.

Photo Recognition an Alternative to GPS?

New software can figure out where you are positioned based on analyzing a photo in near real time. Simply send it a photo from your camera-phone and the software will match the image to a database of locations — such as buildings in a city — and give you back your coordinates.… Read More “Photo Recognition an Alternative to GPS?”
