Submission + - Real 3D TV may be possible (computer.org)

adaviel writes: 3D movies and TV are getting a boost from all the hype over Avatar. But that's not real 3D, it's a stereo effect. If you move to the side, you'll see the same picture, not the scene from a different angle. For genuine 3D, you need holography — essentially, a diffraction pattern recreates the same light rays from a flat film as came from the original solid object. Back in the 1960's IBM made some computer-generated still holograms. Earlier this year, Mark Sich at Shell built a 100Mpixel colour display, and estimates he'd need a 19Tflop computer to run a 2m realtime holographic display. Given Moore's Law and some creative engineering, that may well be within reach in only a few years. We can have the telepresence hookup from Star Wars, without the fuzzy picture and wobbly display, or 3D CAT scan displays for surgeons.

Interesting interview on CBC radio recently with Sue Gardner, Executive Director of the Wikimedia Foundation. She used to work for the CBC, a fairly buttoned-down workplace. When she was asked about the culture differences, and hiring people, she noted that by the time you've seen 500 drunken party photos, you realize that you can't find any young hires that don't have some nonsense in their past. Like the recent study on the effects of porn that could not find any controls (guys who've never consumed any). So a blameless life experience starts to look fishy - either it shows a lack of initiative or courage, or it's been doctored in some way.

Doubt and skepticism are the basis of the scientific method. You don't trust some theory just because the proposer got tenure, you go out and do an experiment to prove it. Then everyone says your experimental data is flawed until two other guys have replicated the effect and got the same result. With climate change, enough other guys have reproduced the results in enough different fields that all the serious doubt was over years ago. Now they are arguing over whether uncertainty in cloud modelling means we get 2C rise in temperature or 3C. BTW, some of the climate models are available for download for those that want to play

Comment Unsigned package, I presume (Score 1) 611

Yes, that's how to make a nonprivileged exploit (mess with .bash_profile etc.) Ideally, the .deb package should have been digitally signed, and the person who signed it should have checked to make sure it was safe. Then if you only install packages from trusted repositories and check the sigs, you are safe (unless the signing keys are hacked, which happened to Fedora. Or they were playing safe, in that they might have been hacked. I forget) In practice, that only works for corporate deployment (protection against autohacking of the entire client PC base). People will always download toys without checking the provenance.

Comment Re:Use the master password feature and stop worryi (Score 1) 1007

I concur. On some Firefox versions I think there was a separate box "encrypt passwords". Use it. Apart from ease-of-use, this method is proof against keyloggers (since you are not actually typing the website password). It also makes it less of a headache to use a different password for each website. The question you should ask is, "Do I trust molewhacker.com with my day-trading password?" and so on. I recently changed most of my online passwords to unique random 20-character strings - only the odd glitch where a site truncated it, or did not accept certain punctuation. To be sure, it's a pain to transfer them to a different computer (I use a GPG encrypted textfile), and my bank uses a method that the browser won't remember (so it still has a short more memorable passphrase...)

Comment for all ability levels, add comic strips (Score 1) 1021

Much as I love Niven, James Hogan, Roger McBride Allen etc. etc., if you want to attract *all* ability levels, try some stuff they are already reading, like Marvel comics. "Iron Man" and Batman are basically Sci-Fi. There's also the whole Japanese anime genre. Not really my thing, though the video "Howl's Moving Castle" was pretty cool (steampunk/anime, maybe). Some of the classics are a bit dated in style (Jules Verne, Asimov, even Heinlein) and are a bit hard to read for the modern generation. Stick to more recent works in the same style, even if they are acknowledged retreads. The Jupiter series by Hogan, Pournelle etc. is Heinlein's Space Cadet etc. rewritten for a new readership. http://www.webscription.net/p-956-the-jupiter-novels.aspx

Submission + - i4i patent ruling - LZW all over again ?

adaviel writes: "As mentioned earlier, a Texas court has upheld US patent 5787449 and prohibited Microsoft from using custom XML in Word products.
So I'm wondering if this will be the Unisys patent all over again, splitting the community into those that choose to pay royalties and those that don't, and generally impeding the free flow of information. To my untrained eye the patent (filed in 1994) appears to be claiming a method of splitting metadata from document content, which sounds to me like stylesheets, not XML. W3C had, I think, published some material on CSS in 1993, and I'd have thought this idea was "obvious" to people in the industry when the patent was filed, let alone awarded (1998)."

Comment Re:Not so. (Score 1) 422

OK - I see http://www.inavx.net/ has real NOAA charts, plus a smattering for other countries. Garmin has most of the world I think - certainly a full set for the Canadian west coast. So for me, apart from not having an iPhone, inavx would not be useful. Maybe NMEA could be got to work on Iphone; pcables.com say they had/will have RS232 cables and that often works, although NMEA is supposed to have opto-isolators. On my Nokia tablet (and Linux desktop) there's Navit which can read Garmin vector maps. Unfortunately all the marine charts are licensed and need a decryption key per GPS set :-(

Comment No marine charts for phones (Score 2, Interesting) 422

A phone is not going to replace my Garmin, because there are no charts (or NMEA). For a boater, that could be life-and-death (MV Queen of the North, no-one checking GPS), or thousands of dollars damage, or maybe just being stuck for 8 hours waiting for the tide (been there, done that, mostly pre-GPS or without the right chart). Google terrain won't cut it because it doesn't show enough detail underwater. Granted, Garmin/Magellan etc. could licence their charts to the phone makers, and the best GPS (or camera) is the one you have with you. On the other hand, for wandering around the city or just breadcrumbing a hike, a smartphone can replace a pocket GPS, plus it's networked. I use my Nokia tablet with (cached) Google Maps in Maemo Mapper, and push routes to it from my PC. A big-screen set would be safer in the car, though (less need to take eyes off the road and fiddle with tiny buttons) and a waterproof/vibration-proof set would be better on my motorcycle (where a GPS sure beats messing with paper maps!)

Comment what happens when humans are taken out of the loop (Score 2, Interesting) 317

As I recall, Harry Harrison's short story (SF) http://en.wikipedia.org/wiki/War_with_the_Robots addressed this issue. The underground bunkers used by the opposing generals to control the robot armies became uninhabitable due to enemy action, so they plugged in a robot officer and evacuated. The war continued, even though the humans had stopped fighting, and it was no longer possible to contact the robots in charge.
