Please do not start with BASIC, it was good for C=64, but only because there was nothing else (at least early on). Now we have python and other (even more?) fully implemented OOP languages, like scheme. Teach OOP first, they can learn BASIC later if they need to, it is harder the other way around.
You need to get a 10K rpm 80+ CFM Black Delta fan on your CPU, man. Guaranteed to take care of all noise, including the road construction in front of your house!
FireWire 400 Mbit/s ~ 50 MB/s Speed close to theoretical speed. Direct PC to PC might possible. Guesstimated speed around 40-45 MB/s.
FireWire 2(?) 800 Mbit/s ~ 100 MB/s New version, Apple already supports on high-end, but likely there is no support for PC, or even interface, or very expensive. Speed close to theoretical speed. Direct PC to PC might possible. Guesstimated speed around 80-95 MB/s.
Drive Swap 1064 Mbit/s ~ 133 MB/s Well, you will have to csave on PC, load on the other one. That makes speed at least half of theoretical one. Drives are not physically capable of these speeds, only around 40MB/s sustained. Guesstimated speed around 20 MB/s.
Gigabit 1000 Mbit/s ~ 100MB/s Direct PC to PC possible. You need 64 bit PCI cards to get colse to 100MB/s. Guesstimated speed around 90-95 MB/s.
Ethernet 100 Mbit/s ~ 10MB/s Cheap, easy, cheap, but slow. No special needs. Guesstimated speed around 9-10 MB/s.
USB2.0 480 Mbit/s ~ 60MB/s Cheap, high(er) CPU overhead. Need PC-to-PC host bridge (might be hard to locate). Guesstimated speed around 40-50 MB/s.
Hoover Dam was way cool. Take the hard hat tour. I costs extra and takes about 1.5 hours, but it is well worth it. Make sure you watch the documentary on show at the theater by the exit, it is very informative.
Please think about the fact that when you are carrying your XPC onto the airplane, the airport security will likely to ask you to demonstrate that it works. You will need to switch it on. You will need an outlet and an LCD to do that. Isn't it going to be a little too much to carry all this around? Is it really worth the 10-15% (or even 30-40%) extra performance, as compared to a laptop?
See opensecrets.org for a very nicely organized info on your elected officials. Very informative read. And it is not just to bulk data, but also the data summaries and presentment that really counts.
Do not buy the argument of "market forces" ot "high quality componenets yield high price and low demand". Half of the Slashdot crowd and most of the geeks would all buy 15K IDE drives if available, even if it would cost almost the same as SCSI. Hard disk manufactuerers already make the drives, it is just a question of slapping a IDE controller board vs. SCSI board on the drive. R&D cost is about 0.00001 canadian cent per drive. No additional investment beyond the distribution channel, and viola you have a new product, that can potentially increase your market share. There will be a low but steady demand for these drives, and if any of the manufacturers spend a little money on marketing it can actually turn into the battle of RPM (a la MHz). I do not see why this would not benefit the makers.
Well, this is my opinion, and now you have it. Peter
Most high end plasmas move their virtual screen around on their physical screen. This is a really slow process (ie. 1-2 minutes cycle time) and it only moves a few pixels up and down, so it is unnoticable. This is because they also realized that burn-in is an issue and they need to do something. I have personally watched a Sony 50+ inch at Good Guys for several minutes but it was unnoticable, unless I put my fingertip at the edge of the picture.
However, it might not protect against burn-in in case of more static screens, like video games or public ad displays.
A much more effective anti-piracy feature built in to Bon Jovi's brand new album is that it is such a crap that no one will want to listen to it let alone copy it or download it. It keeps piracy at practically zero level.
I have seen Minority Report on one of these digital theaters in Westwood, CA. All I can say about it is negative:
- color resultion: really really suck. It appears they use 4-4-3 bits for RGB or something equally inferior. Openeing scene had very visible banding instead of smooth gradients. While this could be dithered, it was not, probably because of compression requirements. It truly sucked, or have I already said that.
- pixel resolution: is OK, but the black space between pixels is visible. That makes the pixels visible, and that sucks. They need a better LCD panel.
Changes they have to make before I consider digital is:
a) higher color fidelity b) possibly higher resolution (1.5x - 2x horiz. and vert. too) c) dead space elimination between pixels d) less agressive compression (ie. bigger storage)

Simple: a very, very, very sloopy engineer. Can you imagine architects planning buildings like we do software?
Yeah, I just hope it does not turn out like the Oracle installation Java mess, yuck!
They have real player streams. We should press NPR to provide divx as well... Know your programs, go ahead and dowload/listen to them.

It does not work on deep pile. Expressly stated in the manual. Medium and short pile is OK. Work wonderfully on our medium pile floor.
WinCE is no more. Got renamed to Microsoft Pocket PC a while ago (like 1-2 years).
Can't beat this one: 12Mbit down / 1Mbit up

Please search US Patent Office. You will find almost every aspect of the wavelets there. More comprehensive reading than any of the books.
It is sad, but true.

I think actually $3000 is pre-government price. The government price would be probably $300,000 per shot. Still somewhat less than cruise missles.
