Here's some tech that I'm really excited about at the moment:

2-D barcodes readable by cell phones. Go read the 2D barcode manifesto. This is incredibly awesome stuff. I won't repeat it all here.



The basic idea is that 2D barcodes can be easily read and parsed by today's cellphones with the push of a button and you can encode arbitrary data using barcodes. URLs, business cards, calendars, anything at all. If I can automatically look up product reviews while shopping or movie reviews while looking for movies at blockbuster, I'd pay good money for that alone.

Apparently this has been around in Japan for a while. Damn, I can't wait to get my hands on this functionality.

UMPC. Intel's vision of an UMPC future.



Also, Intel readies linux UMPC. Yay. I hope the prices of these puppies will start going down too.

Web 2.0 video. A video showcasing the whole semantic web thing, titled "Web 2.0 ... The Machine is Us/ing Us". I don't know if the semantic web is going to live up to the hype (after all it's been hyped before), but the video is a must-see.



Ubuntu. Might just be the best thing to happen to computers. Ever. Feisty simply blew me away. Seriously, after this, even a minute of any other distro is pure masochism.

P.S: this post has too many superlatives.

Considering the difficulty dedicated machine vision systems costing over US$5k have to decipher 2D codes, I don't really expect this to be a viable avenue of input just yet. And for that matter, what should be *on* those darn codes? Que:Cat tried something like that, and it went nowhere damn fast. Back not too long ago all tellie programs had their unique barcode allowing a scanner on the remote to quickly program them for recording. There's been lots of these experiments, and none have found an audience capable of sustaining them.

No way. medryn who visited Japan last year says everyone over there already uses them. Just take a picture with the camera and do some post-processing. It isn't AI or rocket science. And dedicated readers don't cost 5k, they cost less than a cellphone. Obviously, if you're doing it in software, it incurs no extra cost.

"And for that matter, what should be *on* those darn codes?"

Whatever you want, obviously. That's like saying what should be on that darn Internet thing. The standards for encoding data already exist. I can't tell what you're complaining about.

"There's been lots of these experiments, and none have found an audience capable of sustaining them."

Well duh, if no one is creating phone-readable barcodes, no one will use them. The only way to make it fly is to strike a deal with a major retailer to put them on all the products on their shelves. Toshiba was said to be planning something like this in the US last year, and intended to go to market some time in 07. Let's see.

Actually, it *is* AI, and dedicated general purpose readers capable of handling difficult circumstances are very expensive - I make part of my living solving these kinds of problems. But of course, if they're printed in a magazine or something, they'll be easy to read; I read the objective as being they would be on literally everything, and then one of those little handscanners won't cut it, much less a cellphone with some low power CPU algorithm. If that was a misread, then I understand - but then I understand the point of them even less.

Whatever you want, obviously.

Such as ... ?

I can't tell what you're complaining about.

Not so much complaining as expecting it to be another dead end.

Looks like its already available.
