Competitor Compaq is taking a different path. In January, the company announced plans to develop a 100-teraflop bio-supercomputer dubbed Red Storm in partnership with Celera Genomics, the Rockville, Md., company that mapped the human genome, and Sandia National Laboratories in Albuquerque, N.M. Although Blue Gene will be 10 times faster than Red Storm, a Celera executive stresses that the company's machine could eventually match IBM's speed. Unlike Blue Gene, though, Red Storm is being designed for a broader array of life-science experiments and may be used to conduct nuclear research. The supercomputer, set to begin operating in 2004, will cost an estimated $125 million to $150 million to build.

This seems to be somewhat in-line with the cost approximate stated in the press release $90 million. Or am I completely in my effort to undestand what this press release is about?

Portable keyboard. The setup should be such that the screen is inside the portable keyboard, when folded together and this all should be in one package. When folded, it would only work as a phone, kind of similar principles as in the Nokia 9210 Communicator - when opened you would have a natural size keyboard and all.

Mozilla's Baker insists the project's success is critical to the Web's future: "If there's only one browser and that browser is tied to the business plan of a particular entity, it's quite likely that what we see on the Web will be limited." </clip>
In otherwords, eventough the trouble of installing Mozilla instead of IE is a pain for most average people, and the gain might be minimal, people should do it just because: otherwise we are doomed. If this is the motivation, it will never happen. Getting it pre-installed on Windows (AOL,IBM, HP/Compaq to the rescue?) is really the only chance IMHO.
Wake up. Ever seen what happens when you break the ice, with tiny little hole? User nobody will just fall in the bottom and come back as root (berserk mode) - when you get local, root exploits are easy to find.
> PHP doesn't work on 2.0 yet, so upgrading to 2.0 is not an option for us. Now what?
Meanwhile, if you HAVE to use Apache 2.0, run PHP as CGI and you will avoid the version hassle (ofcourse loosing on performance etc). Anyway, it won't take long now to have PHP4 working good as module with 2.x, as the big guys are saying that the Apache API is now kind of stabile for 2.x series.
From the bulletin:
Due to the nature of the
overflow on 32-bit Unix platforms this will cause a segmentation violation
and the child will terminate. However on 64-bit platforms the overflow
can be controlled and so for platforms that store return addresses on the
stack it is likely that it is further exploitable. This could allow
arbitrary code to be run on the server as the user the Apache children are
set to run as.
It seems that thanks to the *nix way of handling processes and their childs, this represents minor threat than on other platforms, in which it is even more easily exploitable as a DOS attack. However, this is not minor news eve for us using *nix breeds.
Usually, when there's an article that clearly does not belong to Slashdot, you can easily spot the relationship between what was "marketed" and OSDN/VA software, so what's the connection in this case??:) Oh, I found it, took just a bit longer: pyDDR.... you were just waiting for someone to link to OSDN, right? So there you are!
square meter is not maybe the correct term to be used in here, but what I meant is focusing the camera so that the image taken covers a flag size of 2 x 2 meters. What's the correct terminology here ? I don't even own a camera, so...:)
The two cameras approach requires relatively high performance. Is there are reason why combination of digital camera and laser based distance meter (accuracy is measured in millimeters) would not be more accurate, reliable and require less computational performance.
Take image, feed the laser distance-o-meter, which scans the distances and embeds the results with the imagedata. We could even have a matrix of the lasers for example to measure the distance on a single shot, for example at 8x8 (64) beams would be already good for scanning an area of few square meters - if the objects that we are looking for area bigger than insects, ofcourse:) To me atleast this aproach is also easier to comprehend than some magic algorithm.

<clip>
The DeepSea chip is hardware implementation of the census correspondence algorithm invented by Tyzx staff...
The algorithm's key concept is transforming a pixel's numeric absolute intensity value into a bit string that represents the pixel's brightness relative ot it's neighboring pixels. For each pixel, The DeepSea chip examines the pixels surrounding area called a neighborhood. A typical neighborhood is 7x7 pixels centered on the subject pixel. Comparing a subject pixel's intensity to its neighbours, the chip produces a relative intensity map (show in the document, page 8). .... the DeepSea chip may not be able to find a valid match for every pixel in the image. Large unformity lit areas of scene may have pixels of identical intensity; for pixels in such area, no single match can be found. Pixels that correspond to an object that is invisible to one imager but the other also do not have matching pixels. ... Once the matching process is complete, the range of each pixel can be calucated using the horizontal disparity of the matching pixels, the focal lenghts of the lenses and the distance between them. The DeepSea chip designates the range or anormalous pixels as invalid.

> They are modifying the Linux kernel to do this. The kernel is distributed under the GPL. So they can't just add some nice security features and start charging for a licence as that goes against the GPL, doesn't it?
As long as they can get their code in the form of loadable modules, GPLed kernel does not restrict them from anything. I don't know which is the case in this case. And yes, you can patent things that utilize opensource, just see the USPTO archives for reference, try searching with keyword 'linux' for example.
> You didn't even manage to sing yourselves out of the contest, did you?;-}
I don't know, but I sure hope that we did. Although I think the most fun part in the contest is to follow the fuss before the contest and the newspapers screaming "this year, we will win" and then all the conspiracy theories when they realize the finnish contestant only won the worst song contest.
You could write such a fancy article about Eurovision Song Contest as well, in which people from 24. different countries interactively select the best of the terrible songs -during the live broadcast-. For example in Finland, you could vote by sending a SMS. But now, that would not be as cool, as a "virtual piano contest".:)
> Not everything is fucking free and ISM bands aren't an answer to the communication quandaries of the known fucking world.
Eh, has your day gone to bad direction or what? I was not saying that everything should be free. 3.4 Ghz is just too close to 2.4 Ghz. Benefits are too little. Higher frequencies might make sense. Also, GPRS and UMTS make sense as long-range solutions. 2.4 Ghz makes sense as short-range solution. Value of $130 million value for 3.4 Ghz in australia is hard to see. Australia has population of 19.7 million. If you got every 200th australian use your licensed bandwidth, you would have to squeeze $1319 out from each just to cover your licensing fees. Am I making any more sense now?
Why would someone transfer data at 3.4 Ghz - and pay this company renting the bit-pipe, as there is the free 2.4 Ghz alternative and both use similar technology and products can easily support both bands?
Regulating WLAN spectrum might be good for everyone - but this is not really what I was thinking about - to me it seems that this company is pissing in the wind. I would quess that what people will do, is to set their machines use 2.4 when it provides reliable enough bandwidth at good enough speed, and only use 3.4 during extreme peek hours. If this is how it goes, getting the $130 million investment on spectrum license (and millions put in other purposes) back might take so long, that we have already warped into next generation of spectrums.
Macrovision "copy-protection" is just as effective as the subject above: words, which can be used to sue you. It would actually be less profitful for them to actually make copying impossible, just get the de-facto standard on compensation for violation, and you get much more bang per pirate.

I am sure things like this will happen in the future, but when it is the reality for majority of people, are we still "watching TV" or do we call it something totally different?
I believe we are fixated to thinking that TV means receiving a broadcast transmission. Instead in year 2015 we might be watching "something+vision" like "D vision" (and your favorite show will be D vision by zero). Any other suggestions on terms replacing TV in future?
