One thing I'd like to point out is that HDTV is broacast in 1080i (1080 interlaces lines) format, but your HD ready TV doesn't always have 1080 scan lines. While your STB may output at 1080i, and your set can read that format, it will often downsample it to 720 progressive lines in the output stage. It's a good thing to check the total resolution when your purchasing an HD ready set.
That being said, I can't tell much difference between 720p and 1080i. But it's helpful to know what your getting when your plunking down a few grand on a television.
Plenty of people don't have an antenna thats good enough to actually *GET* digital television. The last time I hooked my rabbit ears up to my television, all the UHF signals came through with ghosted images or partial static. While digital television doesn't have static, you have to have enough signal strength to actually recieve a channel. For those of us in the burbs, or the boonies, this usually means one of those rooftop antennas. These aren't as expensive as the set top boxes, but they do add up. What gets really expensive is getting someone to install it *AND* running coax to it.
A couple of peices of code that I find pretty are TCL and AOLServer. I know there probably aren't many fans of these 2 products on slashdot of all places, but there both open source and beautiful to my eyes. Some of the highlights are
Both follow meticulous published engineering standards documents found Here and Here.
Both create an easy to use API for extending themselves in C.
Both are great examples of how to keep your code flexable, many portions of this code would be useable in other projects.
Navigation proves easy for both of them. it never takes me more than a few seconds to find the file and function I want to look at.
Everything is well documented.
That being said, I'd also like to point out theres more to an open source project than just the code. A beautiful project includes docs (not just inline with the code), communications channels (mailing lists, newsgroups, etc.), useful examples, FAQs, etc. It takes alot of work to get these things to a useable state by the community.
according to this discussion and the article above, my guess would be a form of transportation sort of like a personal train car, operated electrically by a grounding strip. Kinf of like the way bumper cars are operated with the big metal mesh on the ceiling thats electrically charged. These things are probably light enough that most anyone can lift them, or also have a self-propelled method for short distances.
The advantages of such a machine are obvious. less pollution, probably a reduction in accidents, etc. The disadvantage is you have to fight a multi-billion dollar car industryt who's not going to let something like this happen. As cool as this technology might be, who's gonna take GM, Chrysler, and other auto-manufacturers on when they already have a strong political hold in washington?
That $1000 comes with a cordless vaccum that according to the review works suprisingly well. I could see that adding $300 to the price tag. but the rest is still fluff.
I'm computer literate. I've been running linux for years (as well as just aboutevery other unix product). I'm all for making linux a powerful operating system. But I can't see why I should sit down for hours on end tweaking video settings just to get X working right. I don't see how running a program to get these value would make linux any less powerful. It seems to me like you could edit the file by hand if you think your smarter than the program. I'd also like to point out that sun, sgi, dec, and ibm workstations don't have this problem, even when the monitors were foreign. I ran a ViewSonic 21 PS monitor on my Ultra 10 for years and I never had to configure any sort of modelines or anything.
As lots of people have said, the disks and raid setup can be a problem. Spend some time with vmstat and iostat and determine where the bottleneck is. If you have a throughput problem, you want more controllers in the mix. If your spindle bound, you want more disk. However, I didn't see mention of what type of filesystem your using. I imagine with a mail server that you have thouosands of tiny little files spread across only a few directories. For that situation, it's rather critical to put a filesystem that does binary lookups of your metadata (Such as Veritas). use vsar to look up your inode hits and misses and if the ratio is out of whack, try to break things down to fewer files.

On a couple of occasions I've sent my legislators e-mail (you can find the email address of your senator at http://www.senate.gov/senators/index.cf m. While I've never sent snail mail to them I can confirm that I've gotten a snail mail response back from them every time I've sent them something. It's never been in a timely manner, (the response for my inquiry about allowing local channels on sattelite tv took about 2-3 months) it was at least a response and I knew someone had read the e-mail. -Dan
actually you can change the color. The black with neon doesn't look to bad.

you tell me about this after I do all my christmas shopping there.. well I should have used fatbrain.com anyways. there just better service.
