One of the major problems with today's 3d technology is that the brain of the viewer is used to a specific distance between the eyes. If the distance between the camera lenses of a 3d camera is not the same as the distance between the eyes, your brain will generate a distorted depth image (to shallow, too deep) and you might end up with a major headache (as some experiences). Not to mention that tele/wide lenses causes additional problems of the same nature. To represent a movie that was correct and natural looking for all viewers, you would have to render an animated movie just-in-time for each individual (or maybe a few standard widths). For non-cgi movies, I have no idea how you would do it. I am by no means an expert in this - maybe there's somebody here that could fill in the gory scientific brain details?
Today, though, public spending in Norway is a bit out of control, while revenue from oil and gas is likely to dwindle over the next decades. Unless, og course, we do as we have already started - to invest heavily in oil and gas exploration in poorer countries where the resources are not nationalized to the benefit of the people. The system is rapidly getting less sustainable. Add to this the ethical side of basing your welfare on having to supply massive amounts of CO2 to the atmosphere. It's a great place to live right now, but I am not sure about the long term prospects... Ant then, of course, there is the beer prices!
Nah, not lame, since they don't really try to put a lot of interpretative meaning into it. Maybe someone should make an app to take the dataset and vary the line length (width of the images) to look for more vertical patterns (which also will only have artistical meaning)? I would also like to play the data as a wav with different pitch. Endless possibilities...
Ditto. But we've been through all this on/. before. Here is what I wrote around December 7. last year:
" You're right - nothing new here. However, I beg to diagree re. the Moller concepts. Fixed wings allow for establishing a glidepath and (semi) controlled emergency landings in the event of an engine failure. Helicopters have a similar way of recovering using autorotation and fact that the main rotor has enough mass to allow for controlled landings without power. If the Moller skycar looses a single engine during flight, the vehicle instantly becomes unstable and will drop. It does not have enough wing area to maintain lift, neither does the failed engine have enough rotor mass to be used for autorotation. The only safety device offered is a parashute. Even if mechanically launced, I seriously doubt that the FAA will certify such a thing. It's a neat dream, but I think that investors should spend some money on some professional engineering technology assessment before putting money into that project (even if it flies already).
Yes, I saw it once too. There was a complete traveling exibition on the Soviet space program - I saw it in Dallas around 1991. They also had copies of a few of the Venus probes as far as I can recall. Simple but solid and efficient technology generated many interesting 'firsts'.

I think this was partly mentioned earlier, but I would like to repeat it. Plasma technology is not very well suited for this use. Static pictures will create burn-in patterns and basically destroy the screens very quickly. To be honest, I don't think plasma screen technology is very useful for much at all. They consume much more energy than LCD's or CRT's. They are stated to have a lifetime of thousands of hours, however, I have seen how fast they deteriorate. I would guess that the picture is losing sharpness and brightness noticeably after just a couple of thousand hours. The per-minute cost of using these devices is in other words high. Newer LCD's would be much better suited for these applications. New LCD technology have a much wider angle of view than older LCD's, consume a lot less power, and lasts a lot longer (only panels, not projectors). For high-brightness applications I would suggest a DLP projector DLP is the future!
Being a ham radio operator (although slightly dormant at the moment) I fall for gadgets like these. I've owned a bunch of Icom's in my career. One reason to buy this product would be to bring it with me when I travel. However, it can only do either PAL or NTSC, you have to choose when you order the radio. That's just silly. There's silicone available today that could have made this a TV DX'ers dream (while jetting from one continent to the next). However, with this limitation it just doesn't make any sense to me. I guess I'll have to wait for the -R4 version...?
Links were fine when I put them into the 'post comment' Slashdot editor, but the editor seems to insert a space when it breaks around a long line. Take the extra spaces out and they'll work.
for just one example of a 16:9 HD home projector. The ones that they use in movie theatres are of course of much higher resolution, check out http://www.barco.com/projection_systems/digit al_ci nema/
Bottom line: You can get a lot of DLP for the price of plasma!
Agree! They use a lot of energy (I've seen them up to 700 watts), they get destroyed by burn-in very easily (if you forget your DVD-menu on screen and go away for the week-end, some of them gets destroyed), and the picture deteriorates grossly only after a few thousand hours (per-minute cost of ownership is ridiculously high). Regular tubes are still the best, only rivaled by expensive DLP projectors as far as I have experienced.
Virtual PC environments, complete with IP networking and various common protocols are already being used to catch viral behaviour in software before signature files for a new virus are available. New, unknown viruses will actually spread and send mail from one virtual PC to another inside your PC. There's a paper about it here, which was presented at the Virus Bulletin conference last year: http://www.norman.com/documents/nvc5_sandbox_technology_2002.pdf The technology is available as part of a commercial AV product from this vendor.
First of all, I see no future 'conflict'. There are many players here besider the US, and the International Space Station shows us that we have no problems besides technical to cooperate when it comes to space exploration (except maybe Russian funding). Both the Chinese and the Japanese have programs with great momentum. The system redundancy argument is a good one. I am sure that there's a lot of obscure politics involved, but technically speaking I am looking forward to being able to utilize a GPS receiver that can correlate the results from two independent systems. There were receivers that did that with GLONASS, I don't know if that system is still operable. Competition is of course good, however I think that the potential for commercial competition is fairly slim for the time being due to the high cost of anything space related and that you can't 'claim' resources in space like you do on earth (AFAIK). All in all - the more people/equipment/systems we can bring out into space, the easier it will be to colaborate and go 'where no man has gone before'. Manned mission to Mars, anyone?
I can verify this. On my last few flights with Scandinavian Airlines (SAS), the cabin crew always took note of me using my P800 during flight. I use the organiser etc. with the device in 'flight mode'. It even states specifically in their in-flight magazine that phones are fine as long as they are used in 'flight mode'. Of course, the rule about turning everything off during takeoff and landing is still in effect. On a slightly different note: I worry about the articles talking about decreased flight safety due to cell phones not being switced off. We are dealing with regular, forgetful people here, and I think that airplanes must be made to withstand cell phone interference without it affecting safety. There will always be some bloke who checks in his phone with the cargo while it is still on, or puts one in the overhead bin without thinking about it. People are people, and I think it is unacceptable that the safety of an airplane can be affected by everyday devices that people bring onboard. Should I stop flying?
BTW - I tossed my Palm III two months ago. My P800 is really vastly superior. I can do 'anything' with it, and it is even comfortably small (as opposed to the rather bulky Pocket PC thingies).
Quick comment: The first two points are correct. But when the MS is idle, it will still transmit identification and keep-alive data at intervals, depending on how the operator has configured the network. Additionally, it will do the same whenever it changes cells (when the owner of the handset is moving). Logged roaming data has actually been used in some European courts to prove that somebody was somewhere, even when they didn't talk on the GSM phone. I am a bit unsure about the last point. The specs for those interested can be found at http://perso.wanadoo.fr/cell.sys/recs_br.htm
Some good, valid concerns there. My first concern was of a more practical nature - will the servers take the load when there is a Slashdot jump in the number of clients? My newly downloded client is already spending a lot of time trying to deliver results. I like the concept nevertheless. My perpective on things has become quite 'googlified' lately, I must admit. So I will be using the web-based search client for an alternative view on my searches. However, I am still unsure how much I will be using the client. There's nothing wrong in contributing to a commercial venture, as long as I am (in this case) allowed to use the service for free. But, as already mentioned, there may be legal questions that need addressing.
The duo is slimmer, shorter and narrower. It is electrically compatible. I can take the duo out of my P800, put it into the adapter that came with the phone, and stuff the adapter into my regular-sized memory stick USB reader to transfer stuff from the PC to the memory. Great for brining MP3's with me on the go. Still can't seem to be able to purchase Duo's on the street, though...
It's improbable. I'm a developer in the industry. Marketing of the products is one thing, but the industry ethics when it comes to handling viruses is something completely different. Start out by reading through some back-issues of the professional magazine 'Virus Bulletin' to get a feel for how things work.

S-video is a video format. It differs from composite in that the chrominance and luminance signals are separate. The HI-8 and S-VHS Tape formats both utilize S-Video to enhance the color bandwidth. Connectors for S-Video come in various flavours. The common circular 4-pin plug is universal. More european is the SCART, which can carry S-Video, RGB, Composite, sound, + control signals.
