Yes, of course. I never said the friction was a function of velocity, just that friction can be an equlibrium force for this new force, or friction can be somewhere between zero and equilibrium.
The article is very light on facts. Those looked like metal balls, how do I they know it wasn't an electro-static force? Does it work with those foam balls we all used to build model atoms out of? If it does work, all they have is a motor that seems to work in a similar way to any other motor, but with no practical application (because of the frictionless condition).
It sounds like they're saying the angular velocity will increase if the rotation is frictionless. Why won't this phenomenon cancel out at equilibrium amount of friction and keep the object spinning at constant angular momentum forever? I should also accelerate an object with a small amount of friction but at a slower rate than a frictionless object.
In any case, we're talking about building a perpetual motion machine here and throwing the first law of thermodymics out the window. This makes the cold fusion claims sound pretty tame. At least they said where they were getting their energy, here it seems to come from nowhere.
VESA is not a resoulution

VESA was a local bus architecture before PCI. While it was used for video cards, that has nothing to do with the posible video resolution. I still have old VESA IDE controller.
I agree, that sounds like the AOL 1000 free hours ads that are bundled with a lot of products. If the recording industry tried to do this it would feel like spam and I'd be more likely to buy a car that didn't include it. Then again, with the quality of music coming out these days, I think I'd rather read 1000 hours of spam than listen to 1000 hours of new music:).
Not quite. This is more like Boole working out the basic theories of digital logic in the mid-19th century, long before anyone thought of digital computers.
I'll tell you one thing, my friends who can weld have jobs right now, and I'm working phone tech support.
I agree with you. I thought it was a stupid idea when they got rid of the tech courses and I still do. I value what I learned in auto mechanics a lot more than my practice using a flatbed scanner.
I'm surprised to hear high schools have equipment like a CNC. When I was in HS, the most advanced equipment our metal shop had was a bandsaw and lathe. I didn't even know a CNC existed until University. While I was there, they shut down all the tech labs and replaced them with computer labs to offer courses like "aldus pagemaker" and "corel draw". I thought it was an incredibly stupid thing to do.
I didn't know high schools still had any tech equipment at all.
Chemistry is taught, it's just that most people are too stupid to understand much beyond "acids disolve things". I'm sure the idiot who posted an earlier reply to the parent saying salt is NaCl would be shocked to learn that vinegar and vitamin C are both acids.
Pro: Apply a photo-resist chemical to the entire board, you then project your board design onto the PCB using a special projector (Think this is UV, but can't remember), The board is then emmersed in a developer solution, which combines with the "photo-resist" where the light touched the board, to form a "resist" chemical.
Can you still get the photo-resist chemical? I used to buy the MG Chemicals positive photo-resist, but they don't seem to make it anymore. They just sell the pre-treated boards.
I'm not complaining too much since the green colouring on the pre-treated boards makes them a lot easier to work with, but it was a lot cheaper to coat the boards myself, especially since I'd get surplus board at supremetronic.
What would be perfect is if there were places where you could rent time on a CNC mill, sort of like kinko's for engineers.
I make about 20 PCBs a year (with FeCl3 etching). It would be nice to just go into the store CD and blank copper clad board in hand and rent the machine for an hour for $50-$100 and make 5 boards.
Since the boards are generally all different or at most 2 copies of a single one, I can't justify spending $80 for each board at a place like PCB express. This is just a hobby after all:).
The law did say it was a felony to violate. Since it covers things that are so integral to modern life that everyone does it, just prove that the legislators themselves are violating the law and then have large numbers of people file complaints with the state attorney general's office. Once the legislators have felony convictions they will be ineligible to hold public office.
I simply can't fathom how a law this monomentally stupid has been passed... but it's got to be challenged. A mass protest would certainly expedite it and might prevent similar laws from being passed in other states where they're being considered.
Um...I know you said you're in Europe, but you have heard of the DMCA, haven't you?:).
If you use Red Hat 4.2, you have the full source to your OS which you can patch and upgrade to your heart's content. Also, Red Hat is not an operating system, it's a distribution. There's no reason you can't throw kernel 2.4.25 onto RH 4.2.
I'm not saying MS should be required to patch all their OS's until the end of time for free. They just should not force their product into an end-of-life just to make people pay for the right to enter into a more draconian licensing agreement and break all their custom legacy code that will cost a fortune to repair. It might even be cheaper to pay RH to patch their 4.2 than re-write all the old code. The point is you have that option.
If MS releases well documented source code for NT 4 as well as a free complie environment, I will withdraw my complaint. Until then, MS deserves to die for this.
Isn't this the same place we read about the person who put his PDA in the oven to dry it?
Solder melts at around 350 degrees, the maximum storage temperature for ICs is around 140 degrees F, and 200 for mil spec chips. Heating the whole board and components to 350 for long enough for the solder to melt will destroy the chips.
If you use windows NT, your choice is now pay for the next version of windows or live with the hole. Some companies still use NT because they have custom mission critical software that will not work on a newer OS, and some companies still find (found?) that NT 4 met their needs and there was no need to undergo the expense and re-training effort to upgrade.
If the average user had half a brain, they'd see why this is proof that using MS software is too dangerous for their company. I refuse to use XP because of the activation, but I have to use win2k to get along with my clients. What happens when MS says it's time to force everyone off win2k?

It's a great way to accelerate one of those bicycle-wheel space stations up to speed so they have pseudo-gravity.
