the big difference is, that the wiimote needs to have an IR camera. In the presented method the receptors are cheap infrared sensors. The position is calculated by decoding the patterns the projectors send.
A similar technique has been used to calibrate the image of a projector to a surface. Here is a video: http://blog.makezine.com/archive/2008/04/automatic_projector_calib.html
government and businesses do not always have the same interests.
if the government invests into research it might _not_ need private businesses to pay for the outcome of some research. In other words: the research might benefit every citizen and not just the owners of some businesses.
Not many businesses (let alone individuals) have the means to do important research. The government is, for instance, one of the rare ones being able to build nuclear colliders.
Sure, some "ivory-tower" bureaucrat will decide into which area most of the money will go to. For the US probably a big part will go into the car-industry to catch up with the other countries, but just by balancing the money the bureaucrat can't do _that_ much wrong. In the worst case the US will become specialized in some area.
The real decision what to research is usually done by the universities and research institutes.
I entirely agree with you. I have proposed improvements on the KDE brainstorming forum, but unfortunately nobody really seems to care, or my proposal is just not good enough...

AFAIK KDE-lib depends on many libraries. It would be a waste of bandwidth to bundle these libraries to every KDE-program. If you install Amarok and Koffice you should not need to download these libraries twice.
Sad they do not promote Lilypond more. Many PDFs on the site have been typeset using Lilypond, but only the PDFs are available.

I could help that project by uploading my route tracks but what if I use mapsource (garmin software) to look up the road name am I infringing on something?
According to the wiki page only the institution receives the patent. (It must however share royalties with the inventor.)
I just skimmed over the article, so maybe I missed something, though.
why does the assistant professor get the patent?
I would say he was employed by Stanford. So Stanford should receive the patent. If his research-money was provided by a public institution (some sort of grant), then either the research should be public (patent-free), or the patent should be somehow associated to the country.
I don't see why he gets to profit from the discovery. (After all he was payed to do that. It would have been bad, if he hadn't found anything.)
I can't reproduce your O(N^3). At every level he runs 2.5 times through the list. Once to get its length. 1/2 to split and once to join. -> O(2.5N) = O(N). And there are log(n) levels. -> O(logN*N) His implementation might not be efficient, but it is still in O(logN*N).
proposing multiple OS does not need to be more expensive for Dell. Just dump several encrypted OS' on the disk, and let the user buy the decryption keys. The necessary software shouldn't be that difficult...
next is the scope issue i've talked about suppose i'm dynamically creating objects on the fly and want the callback to reflect the id thus for( i=0 ; i<10 ; i++ ) { someObject[i] = new SomeObject(); someObject[i].onclick = function(){ myFunction( i ) } } every single object will pass the value of 10 to myFunction, because after the function has finished the instance of i in memory that was used is still sat there and every myFunction has been given a pointer to it, not the value it was when it was initialised!
That has been fixed in JavaScript 1.7. A new keyword (let) allows to limit the scope of a variable, which is exactly what you would need here.

one of my favorite riddles: the bridge: 4 men need to cross a bridge in the dark. The bridge can only take two persons at once, and to cross they need a light. The group only has one light, and after two persons crossed one of them need to return (if somebody rests on the other side) to bring the light back. The men are at different shapes, and it takes different times to cross the bridge for each of them. 1: 10min 2: 5min 3: 2min 4: 1min If two men cross together, the faster one has to adjust its speed to the slower one: if #1 and #2 cross together it takes them 10min. Question: How long does it take them to cross the bridge. Bad example (as it goes faster): 1 + 4 -> 10min 4 5min 4 2min --------------------
19min
It's possible to be faster than that (just by changing the order. A bruteforce algorithm would find the solution).
I haven't been following e-ink, but Gumstix, and Holly Gates (a guy btw) is one of the most active users on the mailing list there. He is working for e-ink, and this dev-kit is certainly the first kit containing a Gumstix.
true.
but a gumstix has bluetooth (which is IMO even cooler). Also a Gumstix has more RAM, more flash and is faster.
And (as you point out with your link) you could always add the ethernet-board if you really need ethernet (and in some weeks the double-ethernet board).
We are currently using a Gumstix for a robotics-project, and eventhough the size is amazing, the really big advantage of Gumstix' are their build-environment, and a really efficient and responsive support there.
In addition they have a Wiki-page which has a nice tutorial (I must know it, I wrote it;) and other helpful tips.
Add to that: cutting edge software (latest Linux kernel and gcc) and bluetooth (do you remember the bluetooth-sniper from some days ago? It was based on a Gumstix).
Really cool!
I actually read the article (not just the blog), and it's even less than that.
I'll try to quote the phrase:
"Would the president consider a meeting with Google's concurrent Microsoft, as he converges in so many point of views with its president Bill Gates, [...]? 'Why not?' answered the president."
AFAICS Chirac didn't even say they have so many views in common. And replying "Why not?" from a politician counts next to nothing...

Iris scans are a really bad idea. An iris gives away way too much information. In particular it allows to diagnose many illnesses:

such language exist and become more and more common.
