No gears in the engine and having a transmission with gears is totally different.
Nice try. Am I right in assuming that you've never worked on a car engine? Hint: They don't have any internal gearing at all. That's what the transmission is for. The article is clearly discussing a direct drive setup with enough torque to drive the wheels without any sort of transimssion.
No, I think you understood my post as well as the original post. As I said previously: He wasn't talking about using the 555 to generate a clock pulse. What is the point of using a counter at all!? If you were more familiar with the 555 you would know that they can run *MUCH* slower than 10Hz. The 555 can be set to run at less than one cycle per month, but that's overkill for this application.:)
Suppose it takes 2 minutes to boot your PC. So you set up the 555 so that it charges your timing capacitor to 2/3 VSS in 3 minutes or more. Connect the write strobe of your parallel line to the 555's reset, and autolaunch a program that writes to the parallel port every 30 seconds or so. (you could also use a bit on the paralel port or a control line from the serial port). Each time the strobe hits, it discharges the capacitor and it has to start charging all over again. If your computer crashes, the capacitor will eventually charge to the threshold and trigger the 555's internal comparator and send a pulse to the computer's reset line.
If you're still unclear, let me know and I'll send you a schematic.;)
Um... maybe because the power doesn't go off when your computer crashes. </sarcasm>
He wasn't talking about using the 555 to generate a clock pulse.
He was describing using the 555 as a trigger for a reboot. If you reset with a signal from the parallel port, the capacitors in the 555 timing circuit never full (charge/discharge) so the system doesn't reboot. Of course the time constant of the 555 must be set to be long enough for the signaling program to startup.
Oh and a 555 is usually a LOT cheaper than a step down transformer.:)
... that evolutionary theory, a theory that has been shown to explain the origins of life time and time again...
Don't delude yourself. Evolution explains adaptation, change and selection but it most definitely does NOT explain the origin of life (biogenesis).
Biogenesis is a PREREQUISITE for evolution. Evolution can't take place until you have a system that can metabolize energy and materials from its surroundings and use them to synthesize copies of itself.
Some have tried to make claims about 'molecular evolution' and such, but I've never seen any sufficiently detailed (or even feasable) theory that holds water. Handwaving and speculation is SCIENCE!
Overall you seem pretty intelligent but you have a couple of small misconceptions that are giving you a warped idea of how things are working at a fundamental level. (You're also pretty over the top with some rediculous statements about perpetual motion machines which have no bearing on the discussion.):)
Please don't take this personal as there are many people who make these same mistakes (including engineers at NASA) but they're at the core of the issue here.
In order to stay at the same height there needs to be a force equal and opposite to gravity.
For most of us, this is provided by whatever we're standing on a the moment.
Correct. Now does that force require work or energy to be expended? (yes that's a rhetorical question)
For an airplane, it [lifting force] is provided by the wings. Airplane wings ARE NOY MAGICAL, OVER-UNITY devices, and so therefore you have to maintain at least w worth of thrust devoted simply towards keeping the airplane in the air.
Yes, you need a FORCE equal to the weight. Not necesarily thrust. To believe that a providing a force necessarily requires energy is a common enough mistake, but you should know better if you correctly answered the rhetorical question above.
A hot air baloon stays in the air via a completely different principle than a airplane. In this case the equal and opposite force is generated by simple fuild statics.
And again, this requires no work to fly at constant altitude even though the craft may weigh many tons. Balloons and wings are really not as dissimilar as it appears... The net force on the surfaces of a flying object is what keeps it up. A balloon makes use of the natural pressure gradient already existing in the atmosphere to prvide this pressure differential. An airplane wing generates a pressure differential by utilizing the principle that energy densities along a streamline are conserved.
Try this: hold your monitor above your head for ten minutes. Are your arms tired? That's because you've been expending energy to both hold the TV up and keep it balanced. Although you may not have applied a force through a distance, you have applied a constant force over a period of time.
Sorry, but you just failed physics 101.:)
Try this: Set your monitor up on a shelf. Is the shelf tired? Where is it getting all that energy from!? </sarcasm>
Work is the vector dot product of the force vector and the motion vector. For a plane flying at constant altitude, no work is done by gravity or against it. If you don't understand this, go to the library and get a physics book, or better yet, take a high school level pysics class.
The reason your arms are tired is due to biology and the mechanisms by which our muscles work. For example try pushing your car while it's in your driveway with the brakes on. You get tired, but no work is done on the car by you or vice-versa. There is work being done within your muscles at a much different level but that has nothing to do with the work being done on the car.
Before you post a flaming rebuttal, please take a few minutes to ponder the ideas and see ifyou may be making some unwarranted assumptions.:)
Sorry, aircraft are subject to drag, but gravity is not a loss the way you state. As far as physics is concerned it only takes work to move a force through a distance, so an aircraft at constant altitude has no losses due to gravity. Sure it requires a force to overcome gravity, but that force doesn't do any work. Most current heavier-than-air aircraft use airfoils to create the force needed to overcome gravity (lift) but in doing so induce additional drag. An aircraft like a balloon uses the air pressure to provides the force that counteracts its weight and requires no energy to maintain a constant altitude.
I burn songs to CD, then rip them, then throw away the CD
Have you heard of CD-RW yet?;)
They're extremely cheap too these days. Of course if you have an older writer, it might not burn an RW fast enough for you, but it'd be a good incentive to upgrade.:)
Seriously though, maybe we can get the daemon tools guys to write a CD-R emulator too so we can keep it all soft.
So if we used the same amount of electricity no matter how much daylight there was, then day light savings time would be pointless. Thus the statement "The more daylight we have, the less electricity we use" is valid and important. (If true.)
Just a few hints for you...
Daylight savings time IS pointless.
Daylight savings time doesn't affect the amount of day light.
Although some politicians would love to believe it, they can't legislate the amount of daylight. That's caused by the motions of the Sun and Earth. The setting on my clock has no effect on it.
Remember, you're not lengthening the day - you're taking time from the morning and adding it to the evening.
No, you're not doing either. You're just changing your clock which doesn't have any effect whatsoever on time iself, the amount of sunlight, the length of the day or the distribution of time in the day.
The problem isn't with the clock, it's with when your work starts... which SHOULD be something that can adjust seasonally.
YOU have agreed to accept said advertising in exchange for the advertising offsetting the cost of the service you are using.
Thank you for making my point about brainwashing for me.:) Either that or you live in some advertiser's fantasy land that I've never heard of.;) Care to share with us how you embarked on such an agreement? Who did you make this agreement with, and was it verbal or written?
Agreed.:) You definitely need to be selective in your program choices and PVRs finally make the entire process bearable. Er... I guess that should be "open" PVRs.:)
I can clearly see how refusing to even accept the ads that help pay for what you're watching could be construed as theft.
Ted Turner, is that you?
Seriously though, that is one of the most pathetic things I've read in a while. Either you have some extermely twisted concept of "theft", or you've been brainwashed into thinking you're somehow "obligated" to the media producers above and beyond any agreements or contracts you have with them.
Don't get me wrong... you have the right to waste your time however you see fit, but to feel that there is any legal, ethical, or moral obligation for one to watch ads is absurd. Have you actually SEEN what modern advertizing is like? Advertizing accounts for almost a THIRD of primetime airtime. Most ads are psychologically manipulative, intellectually assaulting and demeaning! Have a little self respect for heaven's sake!
I'd rather go entirely without TV than be obliged to watch ads, and I along with many others would gladly PAY for content without ads if necessary. Most modern ads are targeted toward sheeple that don't have an original thought to their name. If you fall into that category I'm sorry for you.
If enough people rejected mindless and inane advertizing, you might end up with ad-free channels and seperate advertizing channels where the ads were good enough that people WANTED to watch them (ala cleo awards).
Having a custom bios may allow the computer to boot up and run non-TC applications on a non-TC OS which may not be possible with the standard bios. Just because TC has hardware components doesn't mean that the machine must be unusable without that hardware. (The idea is that if you don't boot a TC-OS into a valid TC-system-state then you may be ostracized form other TC-systems, networks, etc.)
Here's a little reading for you.
The initial version of TC had Fritz supervising the boot process, so that the PC ended up in a predictable state, with known hardware and software. The current version has Fritz as a passive monitoring component that stores the hash of the machine state on start-up. This hash is computed using details of the hardware (audio card, video card etc) and the software (O/S, drivers, etc). If the machine ends up in the approved state, Fritz will make available to the operating system the cryptographic keys needed to decrypt TC applications and data. If it ends up in the wrong [untrusted] state, the hash will be wrong and Fritz won't release the right key. The machine may still be able to run non-TC apps and access non-TC data, but protected material will be unavailable.
You guys should hire some real software engineers. Giving your users a 'bios update' program that allows such things at all is insane and is just begging for such problems.
A well designed bios flashing program should check the motherboard version via an actual bios call and strictly allow only proper bios updates for that particular motherboard. If you can't determine the motherboard revision from software, then that should be fixed!:)

Virtually ANY generic capacitor will have low enough leakage to set a delay of several hours.
He didn't. Re-read the post. The X is refering to the same value (the less draconian implementation).
