If you can scrape up the capital, I'd strongly recommend looking into expanding your plan significantly. Buying fiber transcievers for 30 connections is expensive, but getting enough for 10,000 would be a fraction as much per unit. The economies of scale involved are staggering. Even if you have to at least temporarily set up a separate CO for each small group of connections you'd be way ahead.
I think he's more concerned about the external wiring than the internal, and the problem with plain ol' UTP Ethernet is that the maximum network diameter is too small for even a small neighborhood.
I'll bet that the fees Napster have requested from those first universities are low. Very low. $1 would do it.
Why would Napster do such a thing? It puts them on the map, and it gives them lots of participants on fast connections who can help seed the network and make it more desirable.
Obviously Napster wouldn't want that number publicized; they'll want to make money from some of the schools.
Modern games usually don't need super-fast CPUs; even 2 GHz is just fine for most everything. Past that point, bus speed and GPU processing rate are your bottlenecks. So there's less demand for super-fast, super-hot main processors among the gaming crowd, who'd rather spend more on keeping their video card current.
It's not privacy people are yelling about; it's the PERCEPTION of privacy. Lots of folks have known all along that these little spies have been getting installed on people's computers. Some of them have actually done something about it; they install and run software like Spybot Search and Destroy. A few will even switch to an alternate browser like Mozilla to help keep spyware off their machines. But largely they don't care unless it jumps up and bites them on the backside. GMail was planning to do just that, by targeting ads based on message content. Never mind the information would never be audited by a human, it's just the reminder that it's not private that's rankling.
"Symbolism over substance", as Rush Limbaugh pointed out; to most people, it doesn't matter if they have privacy so long as they can pretend they have it. Just like they can vote for people who lie their asses off (and I'm not even going to draw a distinction between either Republicrat party), just so long as they can PRETEND they're electing people who have their best interests at heart.
Use a small solar cell in the receiver, and a diffused semiconductor laser (you may need to use orange or yellow to get enough energy into the solar cell) to beam power over to it.
Beware that for pretty nearly any method of transferring power you can think of, you will be unable to achieve the FCC's Class B certification for consumer electronics. The device is going to wind up emitting a significant amount of energy in the radio spectrum, and even if you were able to focus them almost entirely in the vertical direction (I'm assuming you're trying to feed power to something you're levitating), the Feds will frown on it.
The point to using UDP is so you don't have to fiddle with your TCP/ICMP implementation in order to let the remote make contact without your sending a response.
You now have a time-dependant, unilateral unlock mechanism piggybacked on an existing, allowed protocol, whose reply packets can easily be dropped in every case but a successful auth, making the server invisible to ping sweeps.
What reply packets? I didn't think there were any for UDP, that it was all implementation-specific. Send a reply if that requester is authorized, otherwise just pretend you aren't there.
But my new cell phone's battery is tiny and lasts for 5 days, while I had to get a high-capacity battery for my old phone that was enormous and only lasted 2 at best.
Feeping creaturism and laziness on the developers' part do cause some problems, but things ARE getting better. You may bitch and moan ten years from now because your phone can't support virtual reality, but in twenty years...;-)
I disagree with the terms of this article. He's right if you're talking about putting the fastest possible technology in portable devices -- but we've NEVER been able to do that. If you want a "Moore's Law" for portable devices, it's that when you drop the clock frequency of a processor its power requirements drop still faster. The processors in current cell phones put the original IBM PC to shame, and in ten years they'll be approaching the speeds of current desktop machines, and even though those desktops will be light years ahead, the portables will be plenty nice.
It'd be nice if that camera had a "shutter button", much like your typical film camera or digicam, which instead of signaling the device to take a picture, actually marked that particular time as interesting. Later on you could go back to those shots and pick frames at or near those points. Another feature: Add audio capture so you can whisper to the camera when you take those shots, so you can make notes about the shot.
Dropping the voltage by 5% does not reduce it to the point where it is out of the standard specification -- at least, not theoretically. Spec allows for as much as 10% variation.
This may, however, cause problems for customers at the end of long distribution lines whose voltages are already below 220. If it is continued indefinitely, it may cause further problems as more customers subscribe and there's less play left in the system.
If you've got to swap, then yes, a separate drive to use for swapping is the way to go. It will prevent thrashing between your swap partition and your main partition when working with large executables or large blocks of data. You'd still be better off, however, by blowing some cash to get 2 gigs of RAM and disable swapping entirely.
When you're looking at a scene in reality, your eye naturally focuses on the object you are observing, and that object will appear nice and sharp. Objects in the background will appear blurred and darker as hilights are flattened.
When a scene is rendered in a game there's no way the computer can predict what object someone is paying attention to so it must render everything in focus. As a result, the scene seems unnaturally sharp and bright, especially when the scene isn't placed in bright daylight (the human eye has a greater depth of field in bright light).
Until eye-tracking - and eye focusing - technology is incorporated into virtual reality this is unfortunately not going to be resolved.
...Because most universities have firewalled internet access. BitTorrent was meant to operate with open server ports; clients who are stuck behind a firewall wind up having to upload a lot more in exchange for their download.
I travel a lot in the wilderness, and I'm often in places where the only service available is analog cellular. AT&T's One Rate service was excellent, and I still have their Panasonic Tuff phone (don't know why they ever discontinued this beast, I've dropped it so often and it still works well)...
So if I need to switch carriers, who else still offers analog service?
The idea is simply silly. The fact that the hood opens isn't for women to pop open when their cars break down so they can stare at it and wonder why it's not running. (Men either...) It's for the MECHANIC's convenience. Even if it's a Volvo certified shop, to have to pull the vehicle into a bay and hook it up to some gizmo to lift off the front end to replace a plug wire that fell off the distributor is silly. Especially when the vehicle is still under warranty, and the manufacturer is footing the bill. I suspect if Volvo ever implemented this sort of scheme they'd wind up replacing the front ends with ones with standard bonnets just to eliminate the extra load on their dealers' mechanics.
Let Yahoo fiddle around as much as they want. If they break their page's usefulness they'll lose even more marketshare to Google. If they utilize the extra income to make their search engine turn up more cogent terms more quickly, they may turn out to be the superior model. Let the market rule.
Batteries in parallel (like those 9Vs) are bad, mixing battery types in series (such as AA and 9V in series), or even in brand (different brands of AA batteries) is very bad. If you're going to build this project, use 8 AA batteries in a simple series, unless you like having a pocket full of battery acid.

Than a single coded UDP packet?

Which makes it doubly interesting when China is making threats to prevent Taiwan from "freeing" them...
You really think having a firewall would change that? It might help it a little, but a firewall alone does not good security make.
...Because most universities have firewalled internet access. BitTorrent was meant to operate with open server ports; clients who are stuck behind a firewall wind up having to upload a lot more in exchange for their download.
Isn't that what the Peekabooty project was supposed to fix?

What do you get if you put 20 people from Kiev in one phone booth?
