The difference between copper and fiber is, they're already using fiber quite efficiently.
With the copper wires running to your house, they were only using about 8 KHz of bandwidth before, whereas the cable could carry much more. Adding stuff like DSL and TV just uses more of the bandwidth.
With fiber, you're already using a large part of the optical spectrum in large installations, and the glass will not transmit efficiently past certain wavelength boundaries. -----
The day that OSX runs on my dual celeron, runs all of my X apps at good speed, has full DRI and Xvideo support, and has the lack of bloat that I've come to expect...
That day is when it might stand a fighting change against Linux. Until then... nooo waaaay.
On a corporate note, many companies will not buy hardware unless they can get several bids for it. With Apple being the only supplier for OSX hardware, that cuts them right out. -----
Well, the effect supposedly caused is cancer. However, to cause cancer you've gotta disrupt the DNA of some cells (as best we know), and that requires a radiation of the type called ionizing. That basically means that a single photon has enough energy to strip electrons off of stuff. And the bare minimum needed to disrupt human cells is ultraviolet, or possibly a lot of visible light.
Cell phone radiation is down in the 900 MHz or 2.4 GHz range... far below the many many terahertz of even visible light. So, each photon coming out of your cell phone just doesn't have enough energy to strip electrons off of your molucules. About the only thing it might do is resonate some of your water molecules, heating them up exactly like a microwave oven, except that the power is on the order of 0.1 Watts, so you don't even feel it.
So there can't really hurt you, to the best of our (current) knowledge:-) -----
I feel obliged to correct your terminology. This is not my main field, but I do know a lot.
First off, "maser" and "synthetic aperture" are NOT buzzwords... so get that out of your head.
A maser is a laser-type device that operates in the microwave RF region. That is, it uses feedback and avalanching within a medium to create coherent EM waves, at whatever strength you feel like.
"Synthetic aperture" is a type of radar system. I'm not sure what application it has to sending bits down a power line, but then again I'm not sure exactly what it is. But it has been around for a while, and when you use it on your radar system you get much better results, so like everyody in the world has converted over to it now.
Ugh, the computer I had that in is not working any more. Turn it on, can't get a video signal, it doesn't seem to be booting.
Yes, you can switch the output on and off with lm_sensors, but I'm too lazy and I let the BIOS take care of that at bootup (it'll auto-select the proper mode). -----
I've gotten video output to work very well with a Voodoo3 3000 AGP w/TVout. Not sure of the modelines right now, but they're easy to find on google. 640x480 looks pretty good. -----
Monty, get back to work and code some more, instead of posting a bunch on slashdot!:-)
Actually, this is probably as good a time as any to ask: what is the time-schedule for beta4 and 1.0? I'm really really anxious to see this stuff come out soon, so that Thompson and Fraunhofer can be beat with a stick... -----

the MPEG-2 compression tools at http://heroine.linuxave.net/ get REALLY REALLY good bitrates, comparable to the M$ "MPEG4" codec. Sorry I'm not going to write much, this just looked like the best way to contact you in regards to a somewhat stale comment. -----
Just so you know, I, and several other people, have had lots of problems with GAIM. It crashes a lot basically. I don't really know quite where the issue is, but thankfully there's plenty of good UNIXen AIM clients out there. I myself use Tik (an emacs-lisp version:-) for those times when I need to get on, which is not too much...
But just so you know, if you run into problems, try something else. -----
There's a big difference between current practical beat detection, and theoretical beat detection. I have a feeling he's heading towards the latter, in which case the simple tricks that Winamp/XMMS plugins use won't be good enough. -----
It's because you can license the MIPS core for a good price, and it's a very nice RISC architecture, and probably pretty cheap to fab.
Then again... I don't think that the N64 uses RAMBUS, where are you getting this info? Because the N64 came out in 1997, and I'm not quite sure that RDRAM was ready back then.... -----
Broadcast-quality NTSC MPEG2 takes up 15 Mbps, if I remember correctly. So 20 hours a day you would do just fine with a 15 Mbps link.
The next-largest "standard" line I can think of is a T3, which gives you about 45 Mbps, or three times what you need. Unless you make special arrangements, you might have to do that. Although, if you were looking to expand, that WOULD let you pump out close to three stations running 24/7. -----

Don't you think the main-page poll is a bit stale? It's been almost a month since x-mas.

Something being as significant as the PC is totally different from it replacing the PC.
Personally, I don't think anything will ever truly replace the PC.

Oops. It wasn't there when I posted, I swear :-)
I think I'll just wait for 2.4.1, though..... which HASN'T come out when I am posting this comment, mind you.

My linux 2.4 distro is Slackware 7.1, with a few upgrades. I've been running 2.4.0-test3, 7, and 8 for almost the entire fall semester :-)
Although, 2.4.0 is not for me, as I also use ReiserFS, and I'm pretty sure the patch isn't out yet.

I am so with you on this. Just the alone part, however. I'm not exactly trying to fix the situation, I'm just bitching about it :-)

Those'll be one helluva desktop box.
Actually, no they won't. Not unless all your apps are 64-bit, and even then....

Linux has had full ASF support for a few months now... x86 at least, possibly others.
Go look up "Xtheater" or "libavifile" on freshmeat.

Oh yeah, one more thing.
Don't use any cryptographic software during or for some time after doing this. The results will be much less secure.
And here's one for the kiddies: check out the difference between "bplay -s 22050 -b 8" and "bplay -S -s 22050 -b 8"!
-----
$ cat /dev/urandom > /dev/dsp
/dev/urandom | bplay -s 22050 -b 8
/dev/urandom | bplay -s 32000 -b 8
Optionally, you can change the inherent pitch by doing something like this:
$ cat
$ cat
Or whatever you feel like.
