Ultrawideband might push out Bluetooth physical layer: As I've predicted in various forms, if UWB proves itself, the radio part of Bluetooth could disappear, while Bluetooth's top-level protocols remain. The IEEE 802.15 working group on Personal Area Networking had made great progress with 802.15.1 by approving a subset of Bluetooth's spec with the Bluetooth SIG's involvement. The 802.15.2 task group had several months ago worked out a co-existence plan for living in the same place as Wi-Fi-like networks (and an FCC decision reducing the number of channels that a frequency hopping standard needed to use will make that even easier). The 802.15.3 task group has been trying to establish a base on moving forward in the radio part of things, and many of the proposals coming in rely on UWB. [80211b News]

Smartgun with authentication and minicam. A new South African gun comes equipped with a biometric authentication system (so it can only be fired by its owner) and a built-in minicam (so you can document the circumstances of each shot fired). Link Discuss (via /.) [Boing Boing Blog]

Great, I can just see the new TV series now, "Gun Shot."  Showing all the footage of people getting shot at from the gunners POV, of course for TV, no one ever dies.  Maybe the cops can review the footage and understand why these highly trained officers are such bad shots most of the time.  "One shot, One Kill."

Airport luggage inspectors policing thoughtcrime. A traveller flying to San Diego from Seattle found his luggage had been opened by the Federal Transport Security Authority, who had left behind a note telling him so, on which was scrawled "DONT APPRECIATE YOUR ANTI-AMERICAN ATTITUDE" -- a reference to the "No Iraq War" signs he'd picked up in a shop in Seattle.

So, the Feds are not only inspecting our bags -- and invading our privacy -- to ensure that they are bomb-free; they're now taking it upon themselves to chastise us for our political beliefs? What the hell does keeping bombs off airplanes have to do with winkling out protest signs?

Nothing like a little thoughtcrime policing to undermine the entire mission and credibility of the TSA. Of course, the TSA is maintaining that this wasn't the work of an inspector -- rather, someone at the airport cut the security-seal left behind by the inspector, defaced the "You have been inspected" card, and replaced the seal, all without being caught by the TSA itself (wow, that gives me a lot of confidence in the TSA's ability to secure the nation's airports!).

Nico Melendez, western regional spokesman for the TSA, said the note in Goldberg's luggage will be investigated, but he said there's no proof that a TSA employee wrote it. "It's a leap to say it was a TSA screener," Melendez said.

But Goldberg said, "It seems a little far-fetched to think people are running around the airport writing messages on TSA literature and slipping them into people's bags."

RFID Cards Big in Tokyo.



I still have a couple hundred yen left on the railroad card I bought in Tokyo last September. New York Times reports that these slim, metallic, RFID-based cards are growing more popular in Japan. Some think they are the forerunner to electronic cash. All I know is that it was convenient to charge a card with cash at a vending machine, then simply slap my wallet down on the turnstile at the entrance to any Yamanote line train.

Handheld video. Archos AC340 audio/video player..

Saw this in Wired this month.  Looks cool - at least a heck of a lot cooler than the previous stuff archos has put out.

"The AV340 looks like it might be the real deal when it comes to watching video on the go: it can store up to 80 hours of video on its 40GB hard drive, has a 3.8-inch LCD screen, also plays both MP3s, and, with an optional attachment, can even be transformed into 3 megapixel digital camera."  [via Gizmodo]

Cool - finally.

hong kong flu. BBC: A global warning has been issued about a virulent flu and pneumonia sweeping hospitals in Hong Kong and Vietnam. [Adam Curry: Adam Curry's Weblog]

 

This worries me since it seems to be an airborne virus.  Easy to spread, hard to stop.

More about RFID-based e-money.

In response to my post about RFID-enabled railroad passes in Tokyo, several readers of this blog pointed out:

Robert Renling points out:


"We have this is sweden also on most public transport systems."

Number5 points out:

Public transport systems like metro and bus in Guangzhou, China started to adopt these RFID systems this year.

As to small amount payment, there is another way: mobile phone. You can buy drinks or snacks auto seller machine by send sms to a specified number, and you'll pay for that when you pay your phone bill.

Peter Davidson points out:


We are seeing success in the US with a small fob that fits on users keychain. Called "Speedpass" by the Mobil oil company these little sentient things allow users to charge gasoline and other service station purchases to a credit card. The system is faster than a gas pump that takes credit cards.

In the Chicago area the Speedpass can be used at McDonalds. The device can be swiped past a proximity reader mounted outside the drive-thru window.

Interestingly the Speedpass is intended to be on a users keychain. With the keys in the ignition it requires a two part keychain to be able to swipe the Speedpass without having to shut the engine down and remove the keys from the ignition.

This same user interface issue applies to the new "switchblade" Discover card now available. This is a kidney shaped credit card that swivels out of a small plastic case like a pocket knife. This device is intended to ride on users keychains to make carrying and using the Discover card easier. Fine for self-swipe transactions like mass retailors and food stores but not good for transactions like meals where you'd have to hand your keychain to the waiter to pay the bill. Perhaps there's a quick release of some sort but I've not seen it in their advertising.

Is the Brain Equivalent to a Turing Machine?. From the NewScientist.com: "The world's first brain prosthesis - an artificial hippocampus - is about to be tested in California. Unlike devices like cochlear implants, which merely stimulate brain activity, this silicon chip implant will perform the same processes as the damaged part of the brain it is replacing. The prosthesis will first be tested on tissue from rats' brains, and then on live animals. If all goes well, it will then be tested as a way to help people who have suffered brain damage due to stroke, epilepsy or Alzheimer's disease." [kuro5hin.org]

 

Wow!

Now we have brain and Face implants, what's next?

Seb does it again. Towards Structured Blogging.

Lately I've been thinking about how we could evolve blogging tools to allow people to author more structured (dare I say semantic?) content, so that other people could find their stuff that they find of interest more easily.

Right now what we have, globally speaking, is pretty much a huge pool of blog posts, each implicitly tied to a particular weblog author and with a date slapped on. Now, say I've written a review of the latest Radiohead album into my blog. I'd like others who are interested in Radiohead, or in music reviews in general, and who may not know me, to be able to pick out my review from the common pool in a simple way. Interesting people may come my way because of this.

What we're talking about is getting people to put more metadata on their content. Now allowing it is one thing, and fostering it is another. And I'd say the latter is the bigger challenge.

The importance of feedback

I believe a critical element to get a sustainable system is for people to get reasonably quick feedback in return for the extra effort expended in creating metadata. The Internet Topic Exchange, in which Phillip Pearson implemented the ridiculously easy group-forming design, seems to work because it has a short feedback loop, and might provide a template for where we'd like to go. Here's an illustration of how the Internet Topic Exchange works:

People (on the left) associate select posts with particular topics by specifying a Ping URL; TrackBack carries information about their posts into the Exchange (the fat square), and from there they make it into open topic-specific blogs (on the right). (I don't need to talk about the per-topic Wiki pages here.) Creating a new topic is as easy as inventing a name - anyone is allowed (and encouraged) to do it.

Now, people interested in particular topics will watch them, and this is where the fun comes from. Look at the figure above. Say John (the yellow guy) doesn't know Elaine (the purple girl). But he watches Topic 1 dutifully. Now Elaine happens to come across the channel for Topic 1 and posts to it because she's also interested in Topic 1. Soon John gets her post in his aggregator, checks out her blog, and voilà, he's found a like mind.

In this case the metadata that we have managed to get John, Elaine and others interested in consists of a simple topic identification. This simple scheme has helped such groups as spanish bloggers, emergent democrats, and Austin bloggers coalesce.

Beyond topics

How might we work our way from this model to a different form of metadata, say a music review? Here's a possibility. We retain the basic architecture of the Exchange, but add a new type of blog post called "music review". A drop-down box might enable me to select between "plain-vanilla blog post" and "Music Review". The interface for entering a "Music Review" post might look like this:

(Here I'm assuming there is some sort of standard for music reviews composed of a title, an identification code for the piece of work being reviewed, a rating, and some text. If you know of a similar existing standard please let me know.)

In an ideal world, the "Find" button would pop up an assistant that lets you dig into a music metadatabase (say, MusicBrainz) and quickly home in on an unambiguous ID code for whatever it is you're reviewing (possibly asking you to contribute to the metadatabase if it doesn't know about this piece of work), and puts it in the box.

You fill in the other boxes, click "Post", and your part is pretty much done. Next the system does three things. First, it stores the review in a non-lossy format somewhere on your site. Second, it converts your input into a regular blog post to put in your blog and RSS feed. Third, it notifies one (or more) central indexing service(s), analogous to the Topic Exchange, that knows about music reviews, of the availability of your new review and of its location. This central service also serves a variety of RSS feeds. There could be song-based feeds, album-based feeds, artist-based feeds, genre-based feeds, etc. that you can subscribe to. You could subscribe to the "Radiohead songs and albums" feed and get all reviews of Radiohead songs and albums as soon as they come out. Or maybe you just want to be notified whenever someone reviews a certain song you especially like.

As in the case of the Topic Exchange, these RSS feeds are where the feedback (and the addictive quality) comes from and how new interpersonal links form and people cluster.

Putting it all together

Now to generalize. I talked about music reviews, but the scheme should also work with other kinds of content. Music video reviews, movie reviews (using IMDB?), ad reviews, TV show reviews, game reviews, radio station reviews, weblog reviews, restaurant reviews (perhaps using GPS data), scholarly article reviews... other kinds of content that are not reviews also, such as song lyrics, TV show transcripts, quotes, self-identification data.

Each of these would have (one or more) standard format(s). The basic idea is to let the blogging system support "alternate post type" plug-ins. Anyone should be able to develop such a plug-in (and a corresponding indexing service) for a new kind of post that they want.

If something like this were to become successful it would compete with a host of commercially led user-contributed databases such as Amazon's review database. One advantage would be to put control more firmly in the hands of contributors.

Will people care enough about having their writings under their own control and collected in one place to move away from such databases? I think they might. I know I do.

Other people are thinking along similar lines: Danny Ayers, Alf EatonMarc Canter, Sam Ruby, Ben Trott, Karl Dubost, to name a few. It would be nice to make something like this happen in 2003.

[Seb's Open Research]

Seb is so right on.  First he does the Personal Knowledge Publishing rap, then he wrote about the collective mind "web-enabled group minds at work" - and he's been tracking the TopicExchange for a while.  he's also been the ONLY person so far, besides me - who has contributed to the Topic Exchange channel I created -  'theMatrix'.
