Assuming that there is no safety issue with using cell phones on airplanes, and forgetting for the moment the legal issues, what about the technical issues?
Sure, lots of people would love to use cell phones when the plane is on the ground waiting to take off or heading to the terminal, and that should work fine, but what about at 30+ thousand feet at 600mph? You would be changing cells every minute or two. I doubt coverage is adequate, even if there's no problem with the range.
I think they left out two important categories of algorithms. They should have had at least on data compression algorithm (LZW, wavlet, or something like that) and an encryption algorithm (DES or RSA).
I've wanted to be able to remove the logos from various things I own, but it's not easy to do so. For example, I would like to remove all brand insignias from my car. (At least my dealer didn't add more junk to the car.) I don't feel any need to advertise for Chrysler (the car isn't that great).
Yeah, I was thinking that animation might compress much better than live action, though I agree that a 10:1 compression isn't likely. Of course, you should also consider that SW:TPM was 133 minutes, plus trailers (which were also digital), while most animated movies are shorter (90 to 100 minutes).
It was almost a year ago when I saw it, and I didn't take notes on the presentation, but I think he said that either the audio or the video wasn't compressed, but the other was. That could make it all make sense.
Also, think about it in terms of DVD. DVD uses, what 2G/hour for 520 lines of resolution? So if we're looking at 30G/hour, that's 15 times the resolution (actually a little more, as the audio doesn't need to scale up). Since we're dealing with 2D, that's about 2080 lines of resolution.
I would think they would need better than that; even today, most theater screens are more than 4 times as tall as my TV screen. Of course, that may not be true by the time digital becomes wide-spread.:( [I wish there were a requirement that theaters advertise their sound system and screen size.]
I saw Star Wars: The Phantom Menace in a digital theater. They set up two theaters with digital projectors to demo the technology. Essentially, it's a lot like watching a DVD on a projection TV. The difference is that the projector has many times the resolution, and the player has many times the amount of data. If you looked back at the projector, you saw the three separate RGB lights.
So was it better than film? Not much. Jar Jar still sucked, but there were absolutely none of the glitches you see (or hear) with film. If you happen to be viewing a film with a new print, it's about the same, but if you're viewing a film that's been showing for a week, you'll notice a lot of wear on film.
Oh, and they had some guy come out and talk about the technology before the movie. I believe he said it was on an 800GB raid system. So if they're putting Titan AE on a 50GB disk, they've done a lot more compression. Either that, or some of the numbers are wrong.
Why did you choose Alpha processors for the individual nodes? Why not something cheaper with more nodes, or something more expensive with fewer nodes? What other configurations did you consider, and why weren't they as good?
The word "open" has been used for many things. In some circles, "open systems" refers to Unix systems (as opposed to mainframe systems). These systems use relatively open standards like SCSI.
So OpenVMS runs on hardware designed for Unix systems. Old VMS ran on a Vax.
The Open Source movement is a relative newcomer to the "open" name.
So this should also explain why The Open Software Foundation, now known as The Open Group, is not an open source organization.
So what now, will all the trolls add microsoft documents to the list of things that they post to every thread?
Personally, I agree with the general sentiment--pull the articles containing actual copyrighted text, but don't pull those containing links. (Actually, don't pull the articles, just cut out the copyrighted material and leave a "censored" notice, so the arcives record as close to the original post as possible.)
Of course, it all depends on what kernel version you're using, what hardware you have, and what application.
However, in one case where the application was kernel compilation (cross-compilers for another architecture, mostly gcc and friends), about a year ago, we found Linux was 10-15% faster on a single processor. I think that was FreeBSD 2.8. I know the version numbers have change a lot since then, I don't know if the performance numbers have similarly change.
The primary goal of OpenBSD is security. Hence, it is the obvious choice for a firewall system. In the home environment, the firewall system will also need to provide other services, such as NAT and DHCP.
While my experience is that Linux is faster than BSD, that shouldn't be an issue here.
The only part of this that isn't obvious is why to use IPv6. Actually, that's obvious, too--it's fun to play with new things.
This is another step in the arms race between those who wish to remain anonymous and those who want to know who is doing what.
It's just a matter of time before the RIAA goes after those operating servers on IRC. NetPD is a company that will likely help in this. (In most cases, they could probably get those running servers booted from their ISPs--very painful when high-speed options are limited.)
So what are the next step for those who want to be anonymous? How can I mask my IP number when going online (through IRC, web, napster, etc.)? And I mean really anonymous--no logs to be revealed under court order.
Well, two out of three. This is the last year of the 20th century and the last year of the second millenium. However, we are no longer in the 90's. That naming convention is based on the numbers in the date, so it is zero-origin. So here we are in the 00's, the decade that includes two milleniums.
Simple. They just turn off the civilian signal (or add back in the signal degradation to whatever degree they desire), but only for the satellites involved in that region.
So if any enemies of the United States decide to do something we don't like, we just disable civilian GPS wherever they're operating, and they can't use it. This is especially useful if we've sold GPS-guided missiles to someone that we liked yesterday.
Now if the Cold War were still on, the USSR would put up their own GPS system, so you could buy devices that would use whichever one was operating in the area.
What about cameras that use the 120Meg SuperDisk? Then you could choose between high-capacity or cheap media (take pictures of your friends and hand them the disk).
It seems so obvious; why don't I see them in stores?
(Or what about Zip disks or even hard drives?)
I've heard rumors of a camera that uses MiniDisc being marketed only in Japan; is that true?
I've been interested in one of these, and a friend of mine has one.
One thing that I wanted to try was to use superformat to create floppies that use extra tracks and extra sectors per track--virtually all drives will support this, and DOS is happy with it. Unfortunately, the camera flatly refuses to use any of the specially-formatted disks. (I suspect it would take some firmware hacking to get it to work.)
We shouldn't have generic TLDs. Certainly.gov and.mil should be moved under.us, and non-USA educational institutions don't use.edu, so that could easily be moved under.us.
I would like to see.org,.net, and.com moved to be under.us, as well. At least the *vast* majority should be moved to.org.us,.net.us, and.com.us.
What's the point of generic top level domains, anyway?
You can already do that, but you have to do it yourself.
Telemarketers use computers that detect answering machines (based on tape hiss and such). If you had a phone that put out such noise for the first second or so, telemarketing calls would simply hang up.
Why not ban unsolicited commercial direct marketing? What would happen?
Well, the US Post Office would get an exemption on the grounds that junk mail subsidises other mail (or at least it should; I'm not sure if it's really not the other way around).
For phone, fax, and email direct marketing, a new business would be created. Consumers would get paid to opt-in. You could fill out a marketing demographic survey, and then you would get a credit on your phone bill paid for by the direct marketers who called you.
With opt-in systems, consumers get paid for putting up with advertising. Those who don't want the advertising pay their own way. This is already happening with ISPs. This is also how TV works (you can get free TV with ads, or premium/rental services without).
So which of the multi-plaer RPGs run under Wine? I have Ultima Online running on my laptop (the only machine that still has Windows as a dual-boot option), but I haven't tried running it under Wine. What about the add-on programs? In my case, I use the UO-Auto Mapper, but am not addicted enough to pay for UO Assist.
Terabit and faster networking isn't totally cutting edge anymore. Lucent is talking about sending many terabits per second over a single fiber.
What is interesting is the ability to process packets at that speed. This chip is critical in converting that optical stream into an electronic stream. The other part is a CPU or multi-CPU architecture to process the data. I'm sure Cisco is very interested in this.
So with Lucent figuring out how to send multiple terabits per second over a single fiber, this company able to convert those signals into electronic form, and hopefully soon Cisco being able to process and route data at those speeds, we'll soon be able to forget about bandwidth issues on the Internet. Or to be more precise, the bandwidth issues will become almost entirely limited to the link between consumers and their ISPs.

Ok, now they've converted ANDN to LNUX. The announcement came before the action.
I've wanted to be able to remove the logos from various things I own, but it's not easy to do so. For example, I would like to remove all brand insignias from my car. (At least my dealer didn't add more junk to the car.) I don't feel any need to advertise for Chrysler (the car isn't that great).
I have a few shares of ANDN and LNUX, and they're still separate.
So it sounds like the last details have been agreed to, but the final stock conversion hasn't happened just yet.
Right, with a normal projector. With a digital projector, there is no film, so the color is in the separate RGB.
A digital projector is essentially an extremely high-resolution projection TV. Didn't I say that?
Yeah, I was thinking that animation might compress much better than live action, though I agree that a 10:1 compression isn't likely. Of course, you should also consider that SW:TPM was 133 minutes, plus trailers (which were also digital), while most animated movies are shorter (90 to 100 minutes).

So why not see if the product exists in the CompUSA database?
n fo.asp?prodzip=&product_code={SKU}
http://www.compusastores.com/products/product_i
where {SKU} is a six digit number. I'm guessing it will be in the 270000 to 280000 range. That's only 10K.
Of course, they could have added it to the system but flagged it such that it wouldn't get displayed on their web page.
Anyone care to check?

I received a copy, but our sysadmins have a virus filter built in to the mail server, so the attachment was purged.
That should be the standard approach at any site that runs Windows.

So much for getting a little extra storage.
We shouldn't have generic TLDs. Certainly .gov and .mil should be moved under .us, and non-USA educational institutions don't use .edu, so that could easily be moved under .us.
.org, .net, and .com moved to be under .us, as well. At least the *vast* majority should be moved to .org.us, .net.us, and .com.us.
