Calculating out electrical impedances when you have the R, L and C is also a good use for i, but in my EE textbooks they usually use j notation instead of i. I do agree with the original poster though that i is just an abstract math concept though. It just happens that using it to represent and manipulate 2-D vectors comes in handy.
I find I'm much more productive when I can where shorts and nothing else. I don't get nearly as many people interrupting me when they can see just how hairy my body is.;)
I have to agree with you about having doubts about this. Vinton Cerf and the others that came up with TCP were/are real smart fellars and put a lot of thought into the design. Thanks to guys like Shannon,
Hamming,
Hartley and Nyquist, we have a pretty thorough understanding of the limits of computer networks and sending/receiving information. Unless some wacky/spooky new way is figured out in the far reaches of physics, I don't see big improvements happening in the fundamental protocols.
The 3 seperate conductors for the 220 residential wiring were twisted together? If your talking about one conductor made up of many copper 'wires' twisted together then this doesn't do anything for noise, it just makes the cable more flexible than one made up of one big solid conductor. You have to twist the seperate conductors together to be able to null out any common mode noise and I've never seen utility power cables run this way.
After writing all that I noticed it's a moot point anyways. Twisting conductors together can help remove noise received on the wires but doesn't do a thing for noise or other EM-Radiation emitted from the wires which is the case with BPL.
Found the CBS article, looks like slashdot munged the URL. I'll give it a try Wal-Mart: No Bargain?
Interesting article, though I don't understand how this is only Walmart's problem. Seems like most entry-level, part-time jobs fall into this same category (McDonalds, waitstaff, entry-level factory rat).
Maybe for control path processing it isn't essential, but as soon as it becomes part of the data path, real-time is essential.
Real-time is essential for control processing as well. One of the biggest needs for a *hard* real-time operating system is precisely defined interrupt latency. You have to know that if an interupt is triggered, the cpu will get to it in at least X microseconds. If I have a limit switch or safety cutoff wired to a hardware interrupt on some factory controller, I need the interrupt code to be GUARANTEED to run quickly. I can't have the OS blocking interrupts for a half second when the safety switch is triggered on a drop forge, unless you want to blame the OS for the Red Splat of Death.
I've just never thought of a business giving consumers what they want as a bad thing. If all the people in rural/small-town America loved the small mom & pop stores and despised Walmart, why aren't there bunches of mom & pop stores starting up? Walmart isn't a monopoly and the reason so many people shop there is because they choose to go there. Ask most consumers what is the biggest factor in their purchase and the answer that comes back the most is price. Walmart gives this to them. People choose to buy from the store that most meets their needs.
And how did Walmart kill off all of this competition? By using Thompson.45's and sawwed off shotguns or by giving consumers what they wanted? I've yet to run across a Walmart greeter that's strong armed me into buying anything.
The question is will Wallmart lower the price of CDs if they get the price drop from the record companies to make Wallmart customers happy?
I've seen lots of synical comments about Walmart dealing for lower prices from the RIAA but not passing on the discount to the buyers. I think this whole process Walmart has started with the RIAA is to lower prices for buyers. If you look at Walmart's strategy it's always been about price and volume. Lower the price to differentiate yourself from other sellers and make up the profit difference in increased volume. I'm sure Walmart would love to show everyone in the Sunday ads that they have the newest popular CD for sale for $2 less then Best Buy and Circuit City. Maybe they'll buy a cart load of other discounted goodies while they are in the store as well.
If the RIAA is a 600lb. gorilla, then Walmart would be the 6 MILLIONlb. gorilla. Quote from wikipedia's Walmart entry:
Wal-Mart Stores, Inc. is the world's largest retailer and the largest company in the world based on revenue. In the fiscal year ending January 31, 2004, Wal-Mart had $256.3 billion in sales and $8.9 billion in income. Forbes magazine points out that if Wal-Mart were its own economy, it would rank 30th in the world, right behind Saudi Arabia.

I thought it was 'rooted' in Aussie English.
Et tu, Brute?
No, I think the following message would be much worse:
All your base are belong to us.
You are on the way to destruction.
You have no chance to survive make your time.
This would be all the justification we need to prove that somebody set up us the bomb.
Any alien civilization that has worked past the technical difficulties of putting lasers on sharks is one we should avoid I thinks.
I think I need a new reel of tape in my head then. The one I have now seems to only deal with beer and boobies.

11 binary = 3 decimal. You just have to define '+' as concatenation (and switch mental mode to smartass).
Maybe in warm climates, but I find when it's 20F outside, raising the thermostat doesn't really save me any money.
Instead of drinking coffee in the morning, try blood, it sounds like it might work better for you. Or at least a bloody mary. ;)

Would that be a dotNet profit?
I can't imagine what a lawyer evolves into but it probably has fangs.
From my observations they usually evolve into politicians.

Three of your links don't work and the other is a political web forum. Got any more links to news articles that work?
