  1. either uncentered or even worse an edge not glued down, catching the air. i haven't seen one destroy a laser but i did have to disassemble a drive where the label had flown off and stuck in the drive. to make matters worse it tore the reflective layer off the disc as it did so, spreading that across the drive aand ruining the disc of course. that's why i use a nonpermanent marker and nothing else. (permanent markers will tend to dissolve the plastic of the disc due to their alcohol based solvents. as for imbalance, the normal specs for a cd allow for enough off centeredness of the hole that even a commercially produced disk can wobble fiercely in a high speed drive.
  2. if you went too far you might get a problem with lower oxygenation. (the warmer the water the less oxygen it can hold) but bodies of water are amazingly efficient radiators by evaporating water, so any heat fed into it that goes beyond what it would naturally heat up to should dissipate. take into account that heating water takes a lot of energy, so it would take a lot of heat to change the temperature noticably. if the lake is big enough it should be ok. McLaren (the racing org) has a building for their F1 team that has a moderate sized lake in front. they use that for cooling. the heated water then goes back into the lake via an artificial waterfall/rapids type thingy where a lot of the introduced heat is already reduced through evaporation.
  3. for normal labeling just use a felt tip pen. if you want to give someone a b-day disc or something you should go and buy a cd labeler. it is a holder that will center the self-adhesive labels on the disc so they don't screw up the drive. (remember the high rpm's a fast cd-rom will reach. if there is even a slight imbalance due to the label or an edge of the label raised so it can catch the air and peel off you can have some interesting things happen, up to the label coming half unstuck and screwing up the laser assembly. for best results get a printable cd (one with a top side that can be run through a printer and the appropriate printer (i think epson has ones that do it) that can run a special cd tray through the printer to put artwork on em. what are you looking for labels for?
  4. well, anything with "free" in it...
  5. the ham radio is a broadcast, so easier to listen in to. but it's harder to determine who is using it. like cb radio. sure, you can plot positions by direction finding etc., but the anonimity is better. like cd. "this is rubber duck. fuck all cops!" pretty safe thing to do.
  6. agh. sorry, stirling. it's an external combustion engine, so to speak. it has two cylinders that are interconnected, with the pistons being offset 90 degrees on the crank. there's some interesting links on them if you search for them. from toys to full scale and experimental systems. including an oil or gas fired unit that puts 20 percent of the energy from the fuel into electricity and 60 percent of the energy into heating water.
  7. for cooling that is an interesting deal. like here in PR where it's hot year round being able to boost the efficiency of an AC by using cooled water instead of ambient air for heat dissipation would be good. another interesting app would be to use it to cool the 'cold' side of a solar stirling motor. they have prototypes in the 5KW range that are basically a parabolic mirror of i think 20' or so with a stirling motor sitting in the focal point. i'm sure that could produce more power if the 'cold' side of it were liquid cooled like that. (since more temperature diff on the sterling means it runs with more power.
  8. stable at 4.1 with normal cooling? sweet.
  9. is that the new trigger lock system where you need to key in your pin before every shot?
  10. while we're floating the conspiracy theories: the deployment of internet over powerline is a ploy by the cia/fbi/nsa to make amateur radios useless and force their users to employ a more easily trackable mode of communications.
  11. the interesting thing is that even if a terrorist goes from landline to prepaid cellphones, switching them often, he can be tracked in the pile of connections. take your regular call destinations. some friends and family. if you get a new landline or cellphone, that pattern will stay the same. that is the way you can track people in that database even if they change their phone.
  12. cool. thnx.
  13. what i was wondering about is WoW. if i have 2 comps each with their own copy and 2 accounts, can 2 players be online at the same time? or will the servers balk at both games coming from the same public ip, there be a problem that both comps will want the same ports on the connection for the game or any other issues?
  14. that article is something completely different from the nsa database a lot of people are getting their panties in a knot about.
  15. all they collected was call data, not actual conversations. as to the wisdom of revealing how they are gathering data... all they can do with the data i mine it for supicious patterns and to see who is regularly calling or called by suspicious people. i am all for freedom etc., but what exactly does anyone have to fear from this list of call times and destinations without call content?
  16. a pc outperforming a toy. so where is the surprise?
  17. forget 1and1. i wanted to get them, actually have a family member hook up with them for hosting he wanted done, and they require a mailing and billing address in the 50 states or DC. edit. or canada.
  18. so it's bending the light in an interesting way instead of actually creating a tachyon. (a particle that moves faster than light)
  19. ah. was under the impression that one big flah monster would bring more money than a generated list of text ads collected from googles clients. my bad. edit. then how about an opt-in for porn ads? the site could do with some eye candy.
  20. nope. scary, isn't it? i was just taking him literally...
  21. you mean strap a huge retro rocket to momma earth, slow the orbit and spiral into the sun, thereby having all the energy we will ever need?
  22. um. just saw that in the original post. HHO? wouldn't that be H2O? Water? Hydrogen would be H, in gaseous ot liquid form usually a molecule of two atoms, hence H2. and tommy, i do hope you were kidding.
  23. big deal. the important point is: where does the electricity to perform the electrolysis come from? fossil fuels? nukes? solar? wind? other renewable? if you use power from fossil fuel, you're simply polluting somewhere else. if you're using power from nukes, well, at least you're not really polluting right now, although the storage of the remnants of the nukes is a problem. renewable? good on yer. don't forget that you need the power to run the electrolysis and the power to compress or even liquify the gas, the infrastructure to distribute it and the pressure or heavier metal hydride tanks in the cars. i'll grant you "and all the exhaust is is water vapor" is a great treehugger line, but you have to look at the bottom line of the whole energy input/output.
  24. I say yes.
  25. they might at least be able to tell you if there's hope or not.
