I don't know if the old dog can't learn new tricks or not as i'm only heading toward 50; but they sure seem to be able to string enough of the old tricks together to make them seem new. Also the old dog is more likely to say, "I've wished we could do X for 15 years, so lets make it happen".
I remember see a coaster that i think was in austrailia or maybe austria that the track extended over the edge of a 1500 foot cliff, which should easily give it the highest above the ground title instead of the hisghest above the start point.
The coolest thing about this one will be that its the one drawing the 2-3 hr waits so I can get on the millenium force with only a half hour wait.
For the rest of the/.ers cedar point is on an island so they have very real limits on what they can physicaly fit in; I hope they didn't take out one of the classic wooden coasters to fit this monster in!
what I was trying to say is if only encrypted email is going to get thru to anyone, then the spammer would have to individualy encrypt each email with the addressee's public key. even when automated, it would be computationaly expensive, basicaly a tax paid with cpu cycles instead of money. Grandma isn't going to notice that her email to aunt sally take a half second longer, but she's not sending 640,000 an hour either.
Seems to me that all major ISP's use load ballencing to direct an address to a server that can take the traffic. Set up one sever to query the sender, reply-to, and bounce-to as a valid users in order to delever the email would work. If it does then depending on bandwidth for the recieving server to autheticate these addresses, they could add or remove to suit the available bandwidth and computer time.
If the spammer expects a 0.01% revenue generating Email resonse, blocking that one Email means that they would have to send an extra 10 thousnad Emails to break even, clearly a losing proposition because the ISP's would have only to add a few more authenticating servers to the pool.
Rent server from rackspace for $99.00 a month, get kicked out after a week; move to a server in china, get kicked out after a month, move to a server in russia. It's no problems to make the rounds in this economy, all the server companies are hungry and over built in the.com bubble.
The spammers like Rosky don't use an ISP like we think of them, they rent a T1 line and send traffic from their home office straight to the rented severs all over the world,which relays the spam. When your on a dialup/cable/dsl ISP you're paying for a slew of services like pop/smtp DNS some lame content on the "home page" and of course some band width. All the spammers want is bandwidth, don't need a pop server, nothing is sent back to them, they don't need a smtp server because they rent that from a disposable third party, they don't even need dns because they know the address of the rented server. The telecom that's providing the bandwidth doesn't know or care what they are sendin over the bandwidth, the remote server doesn't know or care until they get complaints and blacklisted.The spammer just moves on and lets the last server company cool off when the server gets blacklisted.
I doubt if many of the Hotmail/yahoo/whoever Email accounts are realy sending out the Emails, have you ever backtraced the ip address to resolve the domains used in sending the emails? These accounts are just random Email addresses that are forged into the from and reply-to address so something is there. Nine times out of ten the accounts are deactivated before you can reply to them anyways.
The best way to stop the spam is to follow the money, somebody is paying. If they track who sleazey mortgage inc is paying to send the spam, it would stop the problem a lot quicker than any protocol change would.
I predict that the problem will disapate farly soon anyways, when spammers start using the trojan/zombie paradigme to send spam it's surly a sign that they are running out of options and computer trespass is something that the feds take a little more seriously than spam.
I had a lot of trouble understanding PKI but finaly it came clear to me; PKI does not need a Certificate Authority because the encryption and authenticity of the sender are two seperate things. 1. to authenticate myself, I need to digitaly sign the documents with my certificate. the validity or trust level is dependent on how rigorously I have to prove my identity to the CA and how much trust the CA itself has. Anyone can set themselves up as a CA, the software is available. 2. to encrypt an Email all that is needed is a public key. the public key allows anyone to encrypt an Email, that only I can decrypt, because only I have the private key. Anyone can have My public key, and they are often stored online in lots of places like keyservers, personal webpages, even on slashdot.
So why would pki encryption help fight spam? the answere is it's expensive, it costs computational time. A guy like Rosky wants to send me a spam, he has to, compose the Email and forge the headers, then he has to get my public key, then he has to encrypt it which takes time, then he has to send it. Rosky brags that he can send 640,000 Emails an hour, there is no way he can do that with encryption, he might be lucky to send 640 (I just guessed that number) an hour with encryption. There is no way that he can pay for a T1 line with a.001% responce rate and encryption, so he gives up and goes into IM spam instead! Of course if he's psycologicaly married to Email spam he could expand his twenty computer set up in his basement to real data center and still do it.
the bottom line is the spammers, and they are few and far between, are very active on a per spammer basis and pay the big bucks. I suspect that a lot of the "open relays" aren't open because of negligence but are open to provide the owner with a degree of plausable denignablity, and the spammer is paying big bucks for a relatively throw away IP address to route his Emails through.
Maybe IP6 will help because it'll give enough IP address out so that dynamic IP's will become un-necessary. Many hosting companies allow user's to send Email that resolves to their domain name; our account at vario allowed this, how they had to set it up is first you'd check your Emails stored on the pop server, which ran a script that opened the relay for one half an hour; with a static IP, they could limit the relay to IP addresses only from authorized IP addresses. IP's could even be reverse resolved so my address could be resolved to budgenator.isp.net so if I send out many complaint generating Emails, my address could be blacklisted instead of a whole block belonging to the isp.
I'm sure there is water, because the atmopheric preasure of mars is about what you would expect from ice sublimating at the martian temperatures. there is very little however, what probably happened is the water vapor in the martian atmophere was broken down by solar UV into hydrogen and oxygen. The hydrogen easily escaped mars's weaker gravity, and the oxygen either escaped also or reatcted with the rock's.
On earth we're lucky because vulcanoes replenish our atmophere with gasses from the planets core.
I work with a silicone material called molloplast b as a dental technician, i used to place a resilient liner in acrylic dentures. The hardest part about useing the silicone is that the time/temperatures required to cure the material are high. I doesn't react with water, and it doesn't harden with commonly encountered temperatures.
In fact the biggest problem I can see with silicon based life is that the temperture required for them to conduct any kind of metabolic activity is very high. Thats why silicones are silicon-carbon polymers, to get the temperatures required for processing down to convientient levels
Water is the simplest dipole that can form. how about CO2? sure you need more presure than with water, and as a solid it's denser than it's liqud form; but it's an excelent solvent and its polar. It fact it's being used as a cleaning solvent right now, I've seen sites promotting it as a replacement for traditional solvent in dry-cleaning clothes.
If I were to try to create life without water I'd probably try liquid CO2 first, but that doesn't exist on mars, not enough atmosphereic preasure there, but it might work on jupiter or saturn.
What I find curius about the NASA data is that they should have found organic chemicals on mars, space has a lot of organics floating around in places like commet tails and not finding them is kinda like not finding smog in LA or mexico city. we've found things like right-handed amino acids on earth, which came from space so why is mars so special that it doesn't have them?
(e.g. "ive never neieded 2 use xwindows over the network, y would any1 ellse!!??"). I'm not a network guru or anything but x over lan was a life saver until I figured out that ip forwarding in linux. I did that to share a dialup connection that was rarely faster than 33K.
yup x windows sucks, it sucked before windows95 was released and it'll suck after they quit supporting windowsME
By the way, how can a chip in your car make the engine blow up? 1. shut off electric fan for radiator. 2. run engine excessively lean to over heat 3. leave transmition in first gear 4. run engine at 9,000 rpm's 5. continue until engine goes boom crunch, bang bang bang and the connecting rods come out the side of the engine block, and the crankshaft falls on to the pavement.
Dave?, What are you doing Dave?, you're not mad at me are you Dave? No HAL I'm not mad at you
The patriot has done an absolutely fantastic job of knocking out short and theater range missiles, a job for which it was not designed. This is a long way from stopping a nuclear re-entry vehicle. We can shoot nuclear artillery through tube 155mm in diameter, assuming that a re-entry vehicle is twice that, it still leaves a pretty small radar cross-section, given the sharpness of the ogive shaped nose i'd guess the cross-section is somewhere between a golf ball and a base ball. Now imagine that the golf ball is traveling 15,000 mph, that's what they are trying to hit.
thanks for the link to the pics, they were cool. If you ever get to metro-detroit Mi area you got to go to the Henry Ford Museum in Dearborn, it's a must see if you're into historic trains plane and cars.
zilog has made z80's from about the middle 1970's, and their unbeatable performance is every probably what force intel to spend the bucks needed to produce the 8088 that was used in the original ibm pc and the 8086/8087 series. I didn't even know the company was still in business.
a lot of people do some realy detailed stuff, the wife wanted a layout in the garden in G gage (45mm track) the scale is 1:24 for wide gage, 1:22.5 for narrow gage, until she saw the price for rolling stock, box cars go for $80.00! The Nice thing is the scale is 1/2 inch to the foot so you can build realistic stuff from scratch if you want; I've seen trestle bridges 6 feet above the ground on the web. This scale is normaly used out doors, you can get steam locomotives, and I really mean steam loco's not just electric that look like steam, they use alcohol to fire the boiler, $435.00 for one locomotive.
how about people like me, I got a bunch of vintage vinyl, shouldn't it be legal for me to download mp3 of the music I own the right to listen to as a working copy, and keep the vinyl for archival purposes? A file sharer has noway to know if my copying an mp3 to my computer is legal or not. I agree that the majority of file sharing is illegal, but I resent any organisaztion assuming that I'm a criminal because of some software logging on to a service. If what I'm doing is ileagal prove it, what ever happened to presumption of innocense?
From what I understand, all grokster does is point participants toward each other; what they negotiate between themselves is between themselves. An analogy would be suing the telephone company, because two parties conspired on the phone to break the law and injured a third party.
I do download music that the owners have given permission to the public to both download and share on p2p networks, and I'm going to do just that, if only to spite the RIAA.
I am going to go and get some mp3 that the right's owners allow to be freely distributed, load 'em in a p2p program and let the bots waste time checking against their lists of "illeagal" music and encourage everybody to do likewise. grind on this you stupid bots!
Easy, just let everybody know you've hacked the school's database, and the quarterback is still inellegable for the homecoming game becuase he wouldn't let you date his chear-leader girlfriend in return for changing his grades!
yes wires are ugly, why not wire the phone jacks with cat5 cable, a RJ11 or RJ12 phone jack plug goes right into a RJ45 jack no problem. just run a couple extra cables to each outlet box. IMHO for every electrical outlet, you should also have a least 1 data/voice outlet with 4-6 cables in it; you can connect them in the future.
when somebody has an office that has bare cat5 cable dangling from the drop ceiling it's ugly and a sign of poor planning or a real cheap-skate

I work in a dental office, and the Dr. likes the cool factor of WiFi, and he's impulsive enough that the ability to move any computer anywhere at a whim is appealing to him. I've argued that wireless isn't HIPPA complieant and all that too. Durring the last re-model,10 yrs ago, I dropped cat5e cable everywhere concievable, after all that he got cheap on me and would spring for a patch panel which would have made changes so much easier. Next re-model lots of cat6 cable should be going into the treatment rooms, I'm thinking computerized charting, digital photography and X-rays, he'll want to stuff all that through a single wap.
But that's just criminal penalties, when he's in prison, he a stationary target for civil suits. any evidence in the criminal trail would also be available for use. if there is enough for a criminal conviction, a civil suit should be a cake-walk.
