I'd like to post an alternative point of view to the prevailing view here.
First, allow me to establish my credentials. I am a long-time Linux hacker, an engineer, and a strong believer in freedom. I'm also the owner of a DirectTivo unit.
Now, when I purchased the DTV I knew that it would not function without two subscriptions: the DirectTV subscription and the Tivo subscription. Never the less, I bought it, and paid the price for a lifetime Tivo subscription.
The Tivo docs very clearly tell you that a Tivo without a subscription will be much less useful than one with a subscription. Tivo makes their money on the subscriptions, not the hardware (a common sight here on/.).
Now, while I agree that it wasn't nice of Tivo to downgrade the functionality of the units in the fashion they did, their primary focus is the folks the get money from, i.e. subscribers. If this guy wanted to do things on the cheap, he should accept the responsibility for his descision.
If I buy a cell phone, it is next to useless without a service subscription of some sort. If I buy a wireline phone, it is a paperweight without a service plan from my local telco. My DSL does me no good if there's not a DSLAM at the other end of the line. We buy things that need subscriptions all the time. You should go into those purchases with your eyes wide open.
Several people have pointed out the price difference between copper and aluminum. I ignored that difference because:
a) The cost of the power lost vs. the delta cost of the conductors has changed from when the move to aluminum was made.
b) The cost of simple AL/CU/Fe cables vs. these new AL/Fiber cables should swamp out the increase. In other words, AL/CU/Fe would probably be cheaper than AL/Fiber.
Why don't they use a layer of copper, which has a much higher conductivity than aluminum. The only reasons I see for aluminum are:
Slightly higher tensile strength than copper, but then that's what the steel core is for.
Aluminum exposed to oxygen forms an aluminum oxide (a.k.a. sapphire) passivation layer, then furthur oxidation stops. Scratch through the passivation layer, and a new one forms automatically. Copper doesn't do this.
However, you could plate the copper with a thin layer of aluminum. At 60 Hz, the skin effect should allow the copper to carry most of the current for a reasonably thin aluminum layer.
The other point that is valid is that normally, fiber optics have less tensile strength than steel. However, I assume (since the article really doesn't say) that the core will be an arimid fiber (a.k.a. Kevlar) with a possible plastic or glass core.
I agree with some other posters. Screw that, get buckytubes working. Then you will be able to greatly increase the current carrying part of the wire.
(The title refers to the slant of the modal average of Slashdot: statistically, it seems most Slashdoters lean left, not right.)
Most of the posters on/. are younger folks. I dare say that if you were to get an accurate poll of the average age of a/. poster, you'd see a Gaussian curve with a mean at about 27. (Of course, there is no good way to actually generate this data, as a poll would place the mean at CowboyNeal).
There's an old saying:
If you are not a liberal when you are young, you have no heart. If you are not a conservative when you are older, you have no brain.
When you are young, it is very easy to say, "NOT FAIR! YOU'RE CHEATING! SHARE!" As you get older, you begin to realize that the "they" weren't cheating, they'd just been playing the game longer than you and better understood the rules. You begin to see that "they" have more than you because they've been working longer. You being to realize that those laws you wanted to enact will have consequences that you will have to suffer (e.g. more welfare == more taxes == you have less money).
When you get older, you realize that you were never given a guarantee that life would be fair, or easy. You realize that sometimes bad things happen to good people, and you are powerless to stop it. That shouldn't prevent you from doing what you can, but you realize you will not be able to solve everything. An analogy: while it breaks my heart to think of all the animals the shelter must put down every day, I cannot adopt them all. This doesn't mean that I shouldn't try to help out with donations of food or money, but it does mean that dogs and cats will still be gassed and burned.
I suspect that, assuming/. survives another ten years without the trolls destroying it, you will see a shift to a more conservative viewpoint (in the classical sense: don't get me started on the bunch of jackassess running the so-called conservative Republican party....).

Read the story more carefully. He contacted the FBI, and after they blew him off he proceeded to work out the information.
Perhaps if he had gone back to the FBI with this information, they would have paid more attention to him, since they could have used his data to go after people DDoSing the big boys.
Gibson finds out how the zombies work. He finds the IRC channel they use for control. He gets the command set.
Rather than turning all this over to the FBI, so that they can start tracking these people down, he makes it known to them that he has it, and publishes it. Now, the people who make these abominations will move their control over to something else.
Granted, the FBI might not do anything with the data. If so, then make a stink about the FBI not doing their job!
Personally, vigilante justice is starting to sound better and better....
Correct: 10 mA through the heart will induce v-fib, however if you are getting zapped through your hand, the current will spread out throughout the torso, and to get a current density high enough to put 10mA through the heart, you'll have to dump at least 100mA total current. Visualize it like this: for any given path, your heart takes up less than 10% of the total cross-sectional area of the chest.
I've said it before, and I shall now say it again: don't just go after the ISPs, go after the domain.
If you receive a spam advertising www.chocolatemonkeynuts.com, look up the DNS server for chocolatemonkeynuts.com, and complain to the service that hosts it. Get the domain pulled, as well as the web site. Web space is trivial to find, but it takes (a little) more work to set up a domain.
Not quite true: read the post again. All modern electronics have bleeder resistors to bleed the charge off the caps for that very reason - so techs don't get shocked.
Secondly, the only thing in a monitor that has anywhere near the charge to kill you is the power supply. The bottle may be charged to very high voltage, but the source impedance is very high. Look at it like this: the bottle sinks about 200-300 watts of power, at 26KVDC or thereabouts. P=VI so I=P/V, so I = 300 Watts/ 26000 V = 11.5 mA, or enough to be felt and that's about it. You need about.1A to kill. And that's assuming the high voltage supply is running. If all you are getting zapped by is the capacitance of the bottle, you will have much less current, and that only for a few milliseconds. The greater risk of damage is from you flinching and hurting yourself.
Now, the power supply, that's a different animal. You have about 300W of power at 300VDC (the first thing any modern power supply does is rectify the AC line voltage to DC). That's 1A of current, more than enough to kill you. Furthur, that's being fed into about 50-100 uF of capacitance, and that will store enough charge to hurt you. Except that the caps in the power supply have 1Mohm bleeder resistors on them, and will drain down within a few seconds of being turned off. The only danger there is if you remove the bleeders - then dielectric recovery will allow the caps to charge back up.
However, IF you don't remove the bleeders, IF you let the monitor have enough time to bleed down, IF you unplug the damn thing before you work, you will be fine.
NOTE: I'm directing this toward cleaning the monitor. You don't need to turn the thing on to clean it. Troubleshooting it is a different matter, since you will have to turn it on to do so. If you are troubleshooting it, then you need to follow all the HV precautions: don't work alone, keep one hand in your pocket (so if you do get bit, the current won't go through your chest, thus reducing the risk of inducing ventricular fibrillation), and use appropriate tools. However, if you have the needed skills to be troubleshooting a monitor, you should already know this, and not need me to tell you.
Trust me, I've worked with everything from 440VAC three-phase power to 40KV laser pulse drive systems to 2KW microwave systems. I'm still here.
The simplest way it to take the power supply outside, and using a source of compressed air blow the dust out.
However, use a source of clean, dry air: don't just go down to your local gas station and use the air for airing up your tires - it frequently has lots of water in it. (when filling your tires, it's a good idea to bleed some air from the air line, and if you see mist, go elsewhere.)
Opening a power supply is really no big deal. The capacitors in the power supply will have bleeder resistors that will pull the charge off them when the power supply is turned off. Just undo the case of the power supply and air it out.
As for a monitor: again, not a big deal. You're not going to be reaching around inside the thing, just hosing it out with compressed air. Don't worry about the charge on the bottle: again, modern monitors have a bleeder resistor that drains the charge off in a few minuts.
Also, the warm up time of an old monitor had nothing to do with "amplifying the power in the coil" - the delay was in heating up the filaments in the tubes used to power the monitor. Until they were hot enough to emit electrons the tubes didn't work. Modern monitors don't use tubes, save for the bottle, and the time for the CRT's filament to heat up is only a few seconds.
However, if you don't feel comfortable opening up your monitor or power supply, then don't. You are the best judge of what you can or cannot do. However, I wouldn't (and don't) worry about it. Just make sure to unplug things when you are working on them.
This is why you should clean you machines once in a while: shut them down (quitcherbitchn about your uptime - it's not a contest!), open the case, and either vacuum (with non-static generating vacuum) or blow (again, with a non-static generating air source) the dust out. Clean the power supply (the 300VDC on the main caps will tend to attract dust) very carefully. Ditto for the monitor: the 27KV anode will pull dust out of the air like a magnet pulls iron filings. (You should see some of the machines I've seen in machine shops/auto garages/printing shops.... Gak!)
Not only will you prevent allergies, you'll keep your system running cooler, help prevent you power supply from sparking out, and have a good chance to check all your fans to see if any are about to fail.
If you are really hard-core, you'll put filters on all intake fans, run positive pressure (i.e. fans blowing in, and air exiting via slots/holes etc.) and clean the filters once a month.
And DON'T SMOKE NEAR YOUR MACHINE! You've no real association for the word "disgusting" until you've worked on a monitor that was used by a smoker. I've seen some monitors that I 'm surprised didn't die of cancer of the CRT, they had so much tar and nicotine on the bottle. You can go through an entire bottle of 99% isopropyl alchohol (DON'T use regular rubbing alcohol, it is 30% water!) and still not get all the gook off.
I just finished converting my server to XFS and LVM. This is a great combination: no fscks if the UPS dies, big file systems, access control lists for fine-grained control of permissions, the ability to add grow the file system without having to recopy everything, file system snapshots for easy and consistant backups.
I am just waiting for XFS to make it into the kernel proper (and kdb, as well. As a developer I'm drooling over getting that in place), and for the major distros to support installing to an LVM group from the start. Now that the SGI team is in scramble mode that means I'll probably have to wait longer. Damn.
In the future, I see the average home having a data server in the basement, right next to the hot water server, the hot/cold air server, and the electricity server (breaker panel). I see this server as a faceless box, much like a breaker panel, with slots that take hot-plug disk drives. Need more storage for video on demand/music/cache (no, I'm not going to use the p-word here. Grow up.), just plug a new drive in. The system sees the drive, formats it, adds it to the arrays, and away you go. Linux is getting to where it could do that. XFS/LVM/RAID are damn important....
Actually, TV's do NOT get their "clock" from the powerline, they get it from the signal.
The original NTSC standard vertical frequency was 60.000Hz - this was done to minimize the effects of the power supply on the vertical retrace. For any given TV signal, the phase of the power line vs. the phase of the video signal would be a constant, and thus any distortion in the vertical scan due to the magnetic field of the power supply transformer would be constant from field to field, and thus much less objectionable than a wavery screen.
When the color subsystem was added to NTSC, the vertical retrace rate was changed to 59.99 Hz. (Don't ask me why, I don't recall off the top of my head).
This is not as much a concern on modern TVs: instead of a big wad of iron and copper transforming the power line at 60 Hz, the power supply rectifies the input to 300 VDC, and then uses a high frequency switching power supply to make the voltages needed from the line. The result is that you don't have the 60 Hz field off the power supply. As a result, an NTSC TV will quite happily run off 50 Hz (as long as the voltage is correct: remember that US power is nominally 120VAC, while UK power is nominally 240 VAC), and a PAL TV will run of 60 Hz (with the same caveat).
When I was in high school (79-83), I always carried a knife with me. I had drugs on my person, and gave them to others. I routinely ignored a teacher, I walked out of class, I walked out of school with a printer one day. I played video games.
Was I horrible? Incorrigible? A thug?
Hell NO!
I carried a knife because it was a tool: I was always being asked to fix things for other students.
I carried asprin in my billfold because I got incredible headaches. When my friends also got headaches, I gave them asprin as well.
I ignored the teacher because he was an imbecile who could coach tennis, but not teach math. He once was unhappy because I found the slope of a line by differentiating the equation in my head, rather than computing (y2-y1)/(x2-x1) as the teacher's guide said.
I left class to go work on the school's computers. I was in charge of the computer room: the principal himself gave me the authority to deal with troublemakers.
The printer was broken and out of warranty, and I could solder the broken connection faster than the local computer shop could fix it.
In short, I was the typical geek. I had several honors, and I am now a (very ) productive member of society, and I've never even killed anyone.
But now-a-days I'd not be let within 100 meters of a school....
A friend of mine mad an interesting point: "We grew up with Johny Quest. The rules were simple: we kill the bad people with guns. We grew up OK. Now these kids grow up with Smurfs and Carebears, and they are doing crack and killing each other!"
... But IPv6 won't be widely deployed until the consumer version of Windows supports it, and can transparently proxy for the old Windows apps that don't understand it. Until BillyBobWinUser can be assigned a IPv6 address and still play EverCrack, it's not going to happen.
Question for the audience: does DirectPlay support IPv6? Does.Net?
This sounds more like holographic computing, rather than quantum computing. In QC, a search would involve manipulating the system until one state is left. In this article's example, you still have to iterate over the frequencies to find the frequency that changed. As I am given to understand QC, were this a true analog to QC you'd simple have one color standing alone, with no searching.
Given that may in Atlanta will be converted, will they change the message to:

I know it's a minor thing the the grand scheme of the universe, but that little error in grammar annoys me as much as anything else in the AOL commercials. It should either be "You have mail" or "You've mail", not "You've got mail."
As a general rule, any sentence that uses "got" is probably grammatically in error.

The printer was broken and out of warranty, and I could solder the broken connection faster than the local computer shop could fix it.
In short, I was the typical geek. I had several honors, and I am now a (very ) productive member of society, and I've never even killed anyone.
But now-a-days I'd not be let within 100 meters of a school....
A friend of mine mad an interesting point: "We grew up with Johny Quest. The rules were simple: we kill the bad people with guns. We grew up OK. Now these kids grow up with Smurfs and Carebears, and they are doing crack and killing each other!"
Something is wrong here....

And people wonder why we need faster routers....
... But IPv6 won't be widely deployed until the consumer version of Windows supports it, and can transparently proxy for the old Windows apps that don't understand it. Until BillyBobWinUser can be assigned a IPv6 address and still play EverCrack, it's not going to happen.
.Net?
Question for the audience: does DirectPlay support IPv6? Does
The scary thing is that Mozilla actually prints "Y'all got mail" on stdout when it receives mail...
Besides, "All Y'all" is no more redundant than "You've got".
This sounds more like holographic computing, rather than quantum computing. In QC, a search would involve manipulating the system until one state is left. In this article's example, you still have to iterate over the frequencies to find the frequency that changed. As I am given to understand QC, were this a true analog to QC you'd simple have one color standing alone, with no searching.
I know it's a minor thing the the grand scheme of the universe, but that little error in grammar annoys me as much as anything else in the AOL commercials. It should either be "You have mail" or "You've mail", not "You've got mail."
As a general rule, any sentence that uses "got" is probably grammatically in error.
When reporting a spam, don't just report it to abuse@[isp] and postmaster@[isp] - if the spam contains a valid link (e.g. www.spammingforjesus.com), then find out who is the DNS host for that domain and notify them, too. Getting Internet connectivity is easy, getting a domain name is (somewhat) harder. Kill the domain and really put a twist in his jockeys...
