The only way to truely close the analog hole is to not have any analog information. That means our eyes get pulled out or supplimented with digital receivers because that last step in any system is a analog transmision from the screen to our eyes. Any flags that get set to no copy well not be there in that step and a camera aimed and synced with the TV could record it and turn it back to a digital form free of what ever flags were set.
I have an HP 8250i. This is a 24x4x4 and this paticular one (there are 2 packagings) is a philips CDD4201. Have had it for about 3 years now and still burns on media just fine. It is reported that the drive with the philips is problematic, but I have not had any problems, but I have also flashed it with firmware for the philips because I don't recall HP releasing any firmware updates and that may have solved some problems (ok, reading message boards seem to confirm that it does solve some problems). Burns CD-Rs fine and CD-RWs fine as well. It can burn mostly everything I have thrown at it.

Relays don't pull all that much power, and thats all that is being powered, as the relay, which is just a switch, allows power to flow to the power strip. So flip on the computer, it flips on a relay which lets power flow to a secondary power strip. They could have done something similar with a triac and optoisolator and been able to pull off the 5v from the PSU.(or used a 5v relay) My dad did something like this off the userport of a C64 and Vic20 to trip some lights, 5v from some source, optoisolator(keep that 120v AC away), and then a triac to allow the AC to flow. When the power was removed, the triac would stay switched until the power it was passing hit 0v, which on normal 60Hz AC happens about 120 times a second.

Ok, I was wrong. The DVB site has under the supported items many things from Echostar (DISH) including some of the satellite receivers. Quick google seems to show that yes DISH is DVB ok. Didn't see any Hughes (DirecTV) and from what it looks like (another google) they use an MPEG2 signal that isn't DVB compatible.
I perfer yahoo's "This is spam" thing for reporting it is spam. Although in my hotmail I have filters for cathing the emails with addresses ending in.phd,.now,.you, and the ones like that. (Heck, I even added those to the filters to my primary yahoo account). I agree though, I get spam on the hotmail, although I have only given to a few friends(7) and never used it any where else, total email from friends is like 1 msg/month or less, because most send it to my yahoo account. Now yahoo, I have an account that I haven't really used that my friends now and it gets no spam messages.
Course right now biggest problem with hotmail is that I can't use my unaltered last name with it, "Glasscock", tells me to use a different one or something... ("Glassc0ck" works but it bugs me that their filter on words won't let me use it unaltered. Anybody else with real names that hotmail doesn't like?)
Interesting. What about decimeters (.1 meter or 10 centimeters), I haven't seen a ruler with them marked as such, but saying that a something is 3.048 decimeters puts it a bit closer to the 1 foot that is used. (or 30.48 cm, or.3048 m, take your pick. they are all the same.)
But if we can prove it was his company that sent it, which we could otherwise they would be falsifing some of the information and would already be in violation, he is a US resident. The WA state law http://www.leg.wa.gov/RCW/index.cfm?fuseaction=cha pterdigest&chapter=19.190 doesn't say too much about where the person is, just that they are a person. They also did get that one spammer out of Salem. And it is $500 or actual damges, whichever is geater.
In QST several years ago they had an article about someone who was sending their data once per day or something via AO-27 (the FM repeater satellite) so that his family could follow him as he moved cross country. IIRC it didn't work too well, but it did work somewhat.
I haven't studied the Xbox live service, but I know of something else that was an online service with a bunch of cheaters. Phantasy Star Online version 1, from what I understand, it was free to participate in and had people who would cheat in the offline mode with gamesharks and the like, then would connect and go PK(player kill)ing. In version 2, you paid to use the service, and agreed that you would be banned if you cheated. I beleive you could cheat in the offline mode, but all your cheated stuff would be useless in the online mode.
They knew when people were cheating and prevented it. Didn't mater if the person had a mod chip, in the game it would just deny the use of your ilgotten games in the online portion. Why couldn't they do something similar for the Xbox Live service. Could it just send like an md5sum to confirm the items are what they are supposed to be? (assumning the mod chip couldn't intercept and rewrite the md5sums of a number of items.) Because aren't most of the mod chips just replace ment BIOSes? If so then the ingame effects would be minimal, they would just be used for booting non-Microsoft sanctioned things.
I can agree with the hardware detection. I have a machine doing router/firewall/server work for my home network, its running Slack 3.4, with a 2.2.10 kernel. It is on its 3rd motherboard, although the first was the closest to a 486 (a MediaGX with reported in/proc/cpuinfo as a 486 and running at 180Mhz, its bogomips was almost 3x the 66Mhz 486 sitting next to it(also slack 3.4, 2.2.12 kernel)). I also had a server we used for yearbook which went from a 486 33Mhz 8MB and a 4GB drive to a Pentium 90 128 MB with the 4GB IDE, 2.0 GB SCSI, DAT, then added a 4.3 GB SCSI, another processor, swapped processors with adapter boards (swapped the 2 90s out for 2 200Mhz MMX down clocked to 180, bogomips/processor went up 10x...), another 4GB IDE drive. I will say that thing was a monster, but it did last for over 6 months (summer!) w/o a reboot, better than the school's NT servers which I think had a high of 1 month.
It is interesting to read about the concept of rings, with the main kernel sitting in the innermost ring. I know that some of the computers my dad worked on out at Hanford were Primes that had some concepts of rings, with the innermost being the highest up on the privilege levels. Not exactly the same I don't think, but this was many years ago. (Hey just went looking, looks as if Primos Revision 21.0.1DODC2A got to the C2 level, so maybe this is more similar then I think)
What about using a floppy (or floppy image on CD el Toro I beleive) that has enough kernel support to start booting the usb device, if you use modules you can just keep a bare basics kernel on the floppy.
I did something like this one to boot a linux install I did to a scsi zip drive hooked up to a non-bios-bootable scsi card. Kinda slow but that was the zip drive/disk fault.
Strapping tape, if it is what I think it is, is also called plumbers tape, and is sometimes used to hook up the pull thing on your sink so you can open and close the drain in the bottom of the sink. We used some of this with the metal strapping that came with our Chimney Mount (18")Sattalite kit because they only had it good for chimneys 18 feet around and ours was 26 feet. (Drilled into the Metal strapping tape that came into kit with 2 holes on each end so it wouldn't use the bolt as a pivot and break.) Its been up for over a year and still hasn't fallen off the chimney. (Installed Aug 2001) (and yes the dish is sitting on it).
Does anybody remember Michael Bolton in Office Space? About how he was perfectly happy until "that no-talent-ass-clown" become popular when, the guy you follow in OS, was 12? This kinda reminds me of that. Semi-normal person getting confused with a celebrity. From imdb.com:
Samir: Why don't you just go by Mike, instead of Michael?
Michael Bolton: No way! Why should I change it? He's the one who sucks.
Bandwidth, most of these I think are likely either CW or voice(SSB, Narrow FM, Wide FM) a few khz at the low end(and a few hundred khz for the wide FM I think), compared to a 1Mb data signal which is (according to http://www.80211-planet.com/tutorials/print.php/97 2261) can be 30 Mhz wide ( now I suspect that is for the full 11 Mbs signal and would likely be less for 1Mbs). These people are also likely running more than 1 watt at 2.4 ghz. I think this is part of the reason that CW at a certain power will go farther than a voice signal at the same power, less bandwidth to amplify and the more finely tuned the filters can be to just receive the signal and not the noise around it.
I have always been under the impression that for part 15 devices that the power is given in mv/m. According to http://www.radioinnovation.com/Howto/how_pass.htm the maxiumum power for a part 15 device in the 2.4ghz range is allowed an average power density of 50 mV/m at a range of 3 meters, and is a transmitter power of -3.4 dBm when used with a perfect 1/2 wave dipole. -3.4dBm is, http://www.qsl.net/vk6zse/wattsdbm.htm, between 500-800 microwatts.
Now I realize that they are using parabolic antennas, but are they still meeting that average power density, I suspect that ERP is likely greater than 1 watt when using directional antennas.
Don't forget in Goonies the one kid that had the variety of items on his person. The oil in shoes, the light, the mini-wench, his father's camera pop of belt thing. I haven't seen that movie in such a long time, I have this feeling there are some more I have forgotten about.
I can agree to the hard drives not failing. I have a friend whose hard drive (Fujutsu) in his Nomad Jukebox died after about 2 years, but that thing had been dropped many many times, even flew off the top of his car as he was turning from a stop onto a 35 mph road, so it wasn't a big surprise. It, the hard drive, was still under warranty so he got it replaced, works fine now. (Plus he gave his nomad a new paint job while it was apart).
Now for destroying hard drives, you ever swap the 5 and 12 volt lines? Fried several hard drives doing that, some did work though, did this about 5-6 years ago with 100-300MB hard drives.
