I beg to differ. Being an ex-geek, now a car guy, I'd love to use the heat my engine throws off.
If the heat is being converted to electricity then there will be less heat. Lower heat in the exhaust alone means lower engine temperatures because the exhaust sytem radiates the most heat near the engine at the headers (the part where the exhaust comes off of each cylinder for you non-car types). Since thats where the exhaust is hottest thats where the devices would be mounted. A lower exhaust temperature means a lower overall engine temperature.
Secondly, the big step is going from 1000 degrees down to 250 degrees. Taking that 250 down to 180 or 160 would likely allow these devices to draw heat from the engine itself. Having these devices draw energy would reduce the work a typical liquid cooling system needs to do, allowing it to be reduced in size.
Newer cars and performance cars are replacing belt driven components with ones powered electrically, most notably fans and water/coolant pumps. Elimiating belts allows the engine to put more power to the wheels rather than turning an accesory. The catch is that these devices need more power from the battery and alternator. Alternators are presently limited to about 150-200 amps, enough for a stripped race machine to run its accesories, but not enough for a street driven car with lights, music systems, and long continuous driving. These thermocouples would add more electrical power to the system and use more of the energy produced by the combustion.
The automotive example is a bit advanced for the time, but in todays science community a potential commercial use is the best way to get money for new ideas.
Sorry if that went on too long, or was too automotive for you slashdot geeks.;-)
Masters of Deception and i cant recall the author. Its not quite history, but its a good insight into the golden days of hacking and the social nuances of hackers themselves. Its based on reality although the details may have been invented by the author. check it out
Its been said before, but its worth saying again. Clear anything you do with your insurance company, and I don't mean corporate help I mean go to your agents office with diagrams and plans if you roll your own.
You have a big decision to make, do you want to keep people from breaking in or do you just want something that makes a hell of a lot of noise if somone breaks in.
All of your exterior doors should be a heavy guage steel of thick solid wood. You need name brand handles and deadbolts on every outside door. You also want good window locks and you want to keep valuables with street value out of the way of windows and nearer the center of the house if possible. Those will prevent someone from breaking in in the first place.
As for a noisemaker, you want some sort of system on every ground floor window that detects glass breaks as well as window openings. The same for the doors.
Go in and talk to the local police and find out what thier policy is on house alarms. You don't want to break local laws and different departments respond differently to alarms. Some will only respond if a neighbor or professional monitoring center calls in and actual burglar, others will go in just for the siren.
Personally, I don't want an alarm system. I use methods and things at home and on may car to keep from being broken into to begin with.
Microsoft.com has no information that I saw on EFS that lists what level of encryption is used. It has continual references stating that it uses public key encryption. The entire thing is user based rather than key based. I wouldn't trust it, even the most dim users would be less likely to give out that key to the super-secret accounting document than 'just' thier login password.
Google wasn't much more help. Admittedly I
didn't look too hard, but there were a few hits on googlge from a newsgroup discussion of "pgpdisk vs. win2k efs" might want to find those and keep an eye on 'em.
Water out of the tap, or water that has had some contact with conductive materials is conductive. Pure distilled water is not conductive at all. Im not sure if this is offtopic, but it was in a thread talking about inert fluids good for heat transfer.
I actually 'downgraded' from aol to AIM when i got to college. I was using aol because its what the parents paid for back home. But when i got sick of seeing how much crap i could download at once (god i love having a LAN into several OC lines), i started using aim to talk to my people. AIM has MORE instant messaging features than straight up aol. as of version 6.0, Aol has no away function, no single click editiing, you cant see whos offline without going several menus deep.
My point is that the people paying for aol to use as acess get fewer useful features than those who use the free AIM client.
Dare i ask why you need to use your portable cellular phone at home in your apartment where im assuming there is a normal phone available?
But if you must use it, do you have acess to the roof? Get up there and see if you have service. Try the same near windows or on a balcony. Check around for interference, I doubt that because your friends phones work fine.
Have you tried an external antenna? Perhaps connecting the antenna on your fone to a larger antenna/array.
Hmm wireless ethernet, dual P3's eh? how bout a beowulf cluster of these.
But seriously, I didnt see anything but im assuming its possible to use that wireless to allow 2 of these robots to work in coordination and send data back to a controller. Anyone got any more info on that aspect?
Try running the secure cable through a metal conduit with a bunch of dummy or less sensitive cables. As previously suggested, have everything sending random packets when not in use. This may not keep the cable secure but it will make it harder to penetrate/find.
Im not intending to bash this invention but,id be more wary of these than liquid. the constant high frequency vibrations may disrupt the ever more precise moving parts of disk drives. And sound is the motion of molecules in a longitudinal wave, heat energy is also the motion of molecules so this could lead to a hotter case than presently normal.
but on the upside, fun with harmonic resonance could come into play with a harware hack....
EXACTLY what i told the guys at rodeo hack. I then saw the personal alarm/tazer area and the fone jacks, if only ma bell hadnt put breakers in the fone line.......
Presently, I'm trying very hard to not download any music from Napsteresque programs because I want the artists to recieve some money for thier work. Fairtunes.com didnt seem to have a working list the last few times i went to it, so at the moment I dont have an option other than paying for CDs.
When I listen to music, read a great essay, hit a good webpage or what have you. I want the artist/author/composer/creator to know that I liked thier work, and if it's a means for them to earn money I'd like to see that they get some, be it a tip jar, banner ad, or just paypaling them a few bucks.
The system where an artist creates a work and then gets less than 5% of the final sale price back from the publisher is wrong. The publishers and promoters should work for the artists not the other way around.
"....I think a key thing missing is the lack of a video camera. While he does mention that this drastically increases the size, it would make this technology MUCH more useful. "
Yes, imagine it. i could use the camera to project an image of what im looking at right in front of my own eye!!!
Ok this is a bit off the wall, its for the tinkerers.
Run your cat5 thru the pipes, have it all exit to the side of the main pipe. Seal this hole airtight. Now connect a hose to the back end of your computers near the jacks, remove the case fans, and add a filter to the fan holes. Now youve got centralized computer air cooling.
Keep in mind ive never used one of these so, im kind of assuming that these CVS systems are quieter at the ends than a pair of 80mm fans.
tried it. that rarely works for the really nasty sites that we're talking about in this thread. you have to close each popup individually, doing so triggers more popups. the only way out for me sometimes is a log off or reboot.
This is very similar to how I feel. We all want musicians to get money for entertaining us, creating great music, and doing thier jobs. Except for a handful of 'big' artists most musicains dont see much of that $15 you pay for a CD. A friend of mine who listens to a lot of underground and small bands pointed this out. What he does is he gets his mp3's from napster/bearshare/etc and then, anonymously, sends the band a few dollars explaining what he did and why.
I ask all musicians out there, aside from making music because you like it, do you care if your money comes directly from the fans (as cash or an online 'tip jar') or as a check from some record company?
What I'm trying to do is to encourage musicians to tell thier record companies to off and put thier music up on a website or file sharing system, and ask the fans to support them.
These programs only seem to regognize text (if you can copy + paste it into notedpad its text). Creating an image from the text (screenshot or whatever) should prevent this from happenening. Although this would be a bandwidth wasting, time consuming thing to do if you dotn want your pages modified its an option.
If I'm wrong please correct me, im running on theory with this one.
What happens if a road/bridge is closed because of a flood. A buisness on the other side looses customers for that day because customers are either unable to navigate an alternate route or no other route exists. Does this give the buisness the right to sue the transpotation department because it was unable to clear the flood?
The flood wasnt caused by the road crews, exactly like Code Red was not caused by Qwest. The hypothetical road crews placed signs and closed roads to prevent further damages to roads and drivers, much like Qwest notifying its customers of the damage and telling them how to fix and prevent further problems.
Most insurance companies often do not fully insure against damages caused by 'Acts of god'. They do this because these events are uncontrollable and unpredictable much like a large scale internet virus. How is damage to the internet by an act of god different to damage caused by an act of god in the real world?
I like the idea of having one worm for an individual hole that needs patched, but how many holes are there in any OS? I hear of at least one major windows hole each month and linux poses a different risk because of the numerous customized versions. There are many more problems to be worked out such as how will the bandwidth problem be minimized? Scanning for uninfected machines while done with good intentions is still scanning and most base installs of firewalls will halt this.
I understand why a vaccine would be a good thing, but in general it would be difficult to install and would not be accepted. The community that slashdot represents would be the first to lash out at such an action.
Despite the benefits, only the users who aren't likely to install patches in the first place would like it. Those who would use patches would resent thier loss of choice and control.
WHOA! . This would never work on the internet at large, but what about mid and large networks/intranets with relatively homoogenous systems. A sysadmin of these wouldn't have to send his interns out to apply pathces manually, just send out a vaccine worm. Updating the major servers might take some hands on work, but the hundreds of NT and X workstations in the cube farms could be patched very quickly.
Despite the do-good superhero aspect of hole patching virii, they will be looked upon as being more dangerous than harmful worms for a few reasons:
1. Bandwidth. The issue with the ILoveYou virus wasnt that itd did anything particularly malicious but that it ate bandwidth on mailservers. A 'good virus' would have to carry enough information with it to know what patches to apply or require a server to check in with to acess a database/list of patches.
2. Special circumstances. For example, a company is testing a secure driver for windows filesharing (samba) and NEEDS to have port 138 open on its server as part of a test. A patch virus would see that as a drastic security risk and close the port, royally screwing up a beta test.
3. Honeypot's. Servers being used to find security risks wouldnt work very well if there were no security holes.
4. Turf. You're a highly trained sysadmin who has spent most of a year setting up a system that runs so flawlessly that you can play Quake all day and NOT be missing any work. Do you really want someone else messing with it.
5. Common courtesy. Pointing out faults is not a good way to help people. Do it on the street and you'd get your ass kicked.
Thats all i can think of. I've done waht i can to create situations that give you the basic idea.
Is there a term for 'good' virii yet? Perhaps something likening it to a digestive bacteria.
Has it occured to anyone else that maybe these "big media" people didn't start as big media? odds are many of them started either waaaaay down the ladder at a big media org, or in a small media org. Nearly all of them are college graduates who likely worked on school newpapers and publications in college and high school. a mass media organization as a whole is evil, however youve got to realize that when you take the individuals who work there and go through the daily grind are often more competent than thier emplyoing company.
Many of the papers listed are respecatble publications as well, who will use the opportunity to reviewe the best a small media outlet has so that maybe in the future they may purcahse works from them for reprint (the associated press sorta does this now).
I agree. Why are they spending time on gadgets. I just read in Popular Science today that Ford has had a "new" idea of using an x shaped race inspuired seatbelt. Hmmm, an extra piece of steel in the roof and a 5 point racing harness would add less than $200 to the cost of a car if they kept the airbags and existing saftey systems in. Now keep in mind these racing harnesses are designed for 150+ mph crashes none of this pansie assed 80mph sheit. Car companies are looking in the wrong directions. Whats better: Making a seatbelt and airbag system controoled by complex computer modules, ooor a racing harness that is guaranteed to keep your entire torso in contact with the seat at all times with some nylon straps, a bit of roof bracing to anchor to, and some good strong bolts.
