I run a small ISP. Your ISP can't delegate ip space smaller than a Class C (256 ips). You need to provide your ISP with Reverse records to insert into there DNS servers. Some may also let you setup DNS on your boxes and setup CNAME's for records on their server. I do this with my upstream provider for a couple of small blocks I get.
Personally I drive a manual shift. If you are a POWER user, or driver, you want as much control over what your machine as possible. You also want to be able to tweak it to get the most from it. I run a smallish ISP 1000 accounts and almost all of our network used to be Windows. I have since converted almost all the servers to linux. My life has been much easer since then. The servers that do break 9 out of 10 times are the Windoz boxes. If I replace the motherboard or video card in my linux machines it's easy to reconfigure the box with less than 10 min of down time. The Windoz boxes almost always need a OS reinstall. When I added a second processor to my linux boxes a simple kernel recompile (while the server is up) and I'm in business. When I put a second processor in my Windoz box...BSOD! Time to reinstall the OS (server down while I do this).
You can run 1 watt into a 6dbi antenna. For point to point you need to reduce your transmitter power 1db for every 3db increase in antenna gain. This means the max antenna gain for 500mw would be 15dbi. Add 9db to the gain to get 24bdi and you need to drop power another 3db or 250mw. 100mw would be legal at 27dbi but not 500mw. Since you need to increase total gain 6dbi every time your double your distance this would make this shot easy with 27dbi antennas and 500mw amps. I have heard of 20 mile links using legal power levals/antennas. The 500mw amps make this easy. To do this legaly would require very high gain antennas perhaps more than 33dbi. This would be the max legal output for 125mw. Most really good radios put out 100mw. I imagine that a 8 foot dish feed with a biquad antenna might do it.
They don't want you to record anything. That way you are forced to watch commercials and such. The Only problem with this is getting this done in a time frame that would head off HDTV. The more HDTV gear that's sold the harder it's going to be to get this done without pissing off consumers. Emagine having to buy a whole new TV just to hook up to cable. Also imagine all the outcry from comsumer electronics company when they find out VCRs and other recorders won't work and what that will do to their bottom line. This won't happen.
After reading the paper I have to agree. In the "real world" this would be tough to pull off. It would work only if the attacker had enough bandwidth to cause congestion for a few secs. On a DS-3 this would require more bandwidth than most people have unless the owner of the DS-3 were already running close to his/her bandwidth limit. Jitter on the net would also make timming such an attack tough on the "real" Internet.
I run a small isp (300 domains) and we do web site hosting for $20 per month. Our mail servers take in about 130,000 emails every day 100,000 of it is undeliverable. In most cases like this we would simply weather the the storm. If your paying a host $5 per don't expect much.
If you leave the fun frequencies (HF, the stuff the Broadband over power interferes with) saturated with noise and even clobber some of the VHF frequencies, who will want to buy equipment for use only when the power goes out. Also consider that while the power was out in some area it wasn't in others. The HAM at the recieving end may hear nothing but static.
A lot of the value that HAM radio provides in an emergency comes from the large number of people who have them who wouldn't if they could only use them when the lights went out. Take away the fun and no will want to bother.
I have also talked with several people who have traveled all over the world in small boats and nearly all agree that the most reliable communications is HAM radio due to the large number of "ears" listening.
When I got my first computer (Apple II) in 1981 I dreamed of what I could do in the future with a "more powerfull" computer. It would be neat to have a high res screen so I could use it to help design circuits. Maybe a 16 color display. I thought that the rotating shield displays they showed in Star Wars would be neat. During the day you could buy 68000 10MHz accelarator boards for your Apple. 10MHz!, 512K RAM, WOW. What neat things could I do with one of these.
My imagination came utterly short of reality. Real time full color lifelike rendering virtual realty gaming (Quake, Counter Strike, Tribes) was far beyond even imagining. And of course the GUI desktop was not anything I could have imagined. Many of us have computers that put the first Cray super computer ($10,000,000, 100,000 Watts of electricity) introduced in 1976 to shame. I think I'm still in shock. I can't wait to see what another 20 years brings.
I have been using the excellent utility ASK (Active Spam Killer). This uses the challenge response technique. It's blocked 670 SPAM messages in the last 10 days. It's been around for a while. I thought that an idea had to be "non-obvious" to be patentable. Lots of people comming up with an idea thats not obvious.
I've slashdoted a few times. We have 3 T1's and didn't have any trouble. If you want a real host don't think you will get it for $5.95 per month. A single T1 can transfer over 450 Gigs per month. If your trying to host with a cheapy hosting company that only allows 15 Gigs of tranfer per month then expect this. Get a real host.
Your trouble may not be dust. I have noticed that the fans in PS's in the last few years (5-8) to be crap. Myself and a friend Mark go to HAM fests and look for older "quality" fans. Panaflow a Papst seem to be the best although NMB fans also seem to be much better than the new stuff. I have only had one Panaflow go bad in over 15 years and I have never seen a Papst fan go bad despite the fact I have several over 18 years old.
The folks at asciipr0n.com didn't have to badmouth slashdot. If we had to ask before linking the web would quickly colapse. If you didn't have enough bandwidth don't blame slashdot. What good is putting up pages on the web if you don't want people to see them?
Serveral companies make very high quality vacume cleaners. Look at Kerby and Electrolux. If you think about it, a vacume cleaner has one of the toughest jobs. Suck up dirt and still work after hundreds, even thousands of hours of use. My grand mother had an Electrolux that was the standard in the day (1960's). We had that vacume the whole time I was living in the house, about 14 years that I can remember. Since I married my wife in 1984 we have had to buy four vacume cleaners. You can still get an Electrolux but now they cost somewhere around $1000 (10+ year warranty). The cheap vacume cleaners cost about $200-$250. You can have quality if you want to pay for it.
Floppy drives. An old 5.25" drive cost about $50-$60 in 1989. I have lots of old 5.25" 1.2Meg disks I can still read/format most of them. 3.5" drives cost about $7. About half of my 3.5" disks will not format now.
I think electronics quality has dropped somewhat. However, more intregration has made some electronics more reliable. Electrical contacts can be a major source of trouble for electronic devices. My old Apple II has about 80 chips, all in sockets to make it easy to repair. It dosn't work now due to dirty socket contacts. The quality problem seems be worst when electronics have mechanical parts, VCRs, CD Players, Disk Drives.

That one should make you all wet. And all you need to implement floating point math is a bunch of small round balls floating in a bucket. Wouldn't want to be around to see a core dump.
The article says they could use the motion of the arm, which is produced in the first place by a difference in charge, to produce electricity. Don't you already have electricity by the differing charges! Why have any moving parts!
Supose that someone in the CIA that has since retired wants to reveil that he was the one that shot Kenedy years from now (to avoid his family being subjected to whatever). Politician's who want to reveal secrets long after they are dead. There are lots of examples of delayed release that would be applicable and useful.
What is needed is a way to encrypt the info with long keys and release the decryption keys at a predetermined future date. One could setup servers on various parts of the net to release pieces of the key. That way if someone were to track down one of the sites with the info it wouldn't compromise the secret.
Perhaps creat a service where you would store the info after the subscriber encrypted it with a key that had a future relase date. You would need to pregenerate all the keys needed for say the next 200 years. Publish the encryption keys. Breakup and securely store the decryption keys. Every year the "next" decryption key gets released and the stored info could be viewed. Since some of the info stored would be very tempting for some powerful people to destroy/reveil early you would have to find a very secure method of storng the decryption keys. One of my favorate idea involves sending probes into space that would transmit the keys at the right time back to earth. You would want at least two for redundancy.
The WAP11 Ver 2.2 is supposed to put out 100mw. It's possible that your test setup is simply to close together and your saturating your receivers. Also make sure both are in the clear so you don't get reflections that could combine out of phase with the main signal. I had this trouble when testing helical antenna gains indoors. Moving outdoors into my yard seems to have fixed this problem. I have been able to get the older WAP11 Ver 1.1 to work at over 1 mile with great results using home made helical antennas.

I have found some very small USB clients on ebay for $40 that I have had working through over 30 feet of USB extender cable. These unit are very small (smaller that a pack of cigs) and have a removable antenna (sma connector). I am working on weather proofing them for pole mounting.
I own a smallish ISP in Florida. We have been looking at this for some time.
The problem is the cost of getting the neighbors equipment. Wireless equipment starts at around $100 and goes up from there. With the Phone companies and the cable companies trying to knock each other out with signup free offers this is a hard sell. Comcast is offering free sign/equipment and $20 per month until the end of the year. $40 after the end of the year.
Also as stated most cable and DSL providers prohibit sharing of any kind. Some even go as far as to say it constitute "theft of servervice".
Also setting up the antennas and running the coax cable inside and hooking everything up is a a very labor intensive problem. Also the range of the low end equipment along with ever present "line of sight" problem would mean selling to a fairly small radius (1/2 mile is what I think would be safe). This would mean finding enough people within this radius to make it worth while.
We tested a pair of Linksys WAP11's with homemade antennas in point to point mode and got a very solid connection at 1.1 miles (across the river where we had clear line of sight)
We tried starting one of these in the neighborhood where my head tech lives. We distrbuted flyers inviting everyone (about 30 people) to come over to his house for a meeting to answer questions and see the equipment needed. No one came. I am about to try here where I live and use a door to door sales technique.
Since I own an ISP (www.cyberstreet.com). I am aware of the need to log everything. We would assign everyone a static IP so we could quickly track down any spammers/ DOS attacks. This would even be easer than doing this with dynamic dialup. But make no bones about it, this is a lot of work. We are activly looking for people in South West Florida who want to do this in their neighborhood. We would supply the High Speed connection and the local rep would make contact with his/her neighbors. We would take care of logging and most other server issues. I will make a future post if this goes anywhere.
