yeah! almost 2 billion NAT addresses behind almost 2 billion ip4 addresses times 65K port numbers is about 260 x 10 ^ 21 portals of communication, like HALF A MOLE.
OpenBSD is still my favorite; though it would have a somewhat longer list of needed items to be made into an "enterprise" server (if the project ever even went in that direction). I was just telling how I came to be interested & fascinated in FreeBSD recently.
I'm involved in an Oracle on Solaris/sparc to Linux/Intel migration, and I can't but thinking why not also FreeBSD for the enterprise? It has the fibre HBA drivers for SAN, it has a volume manager, it has a very stable filesystem (moreso than ext2/3), it can run Oracle with Linux emulation libraries, has SMP, a fantastic TCP/IP stack, easy installation/upgrading of ports & packages.
I never used FreeBSD until a few months ago when I tried to get my favorite, OpenBSD, up on a very weird 1U Intel based server I picked up on eBay from a failed telco. Versions 2.9 to 3.3 of OBSD wouldn't work, it would hang in the idle loop FreeBSD 5.x has been running fine on it (don't know why)
Less than 1/100th of the current price, 6 years from now on eBay. This new wave of products should shortly allow me to upgrade from my R10K Indigo^2 to a R12K based box for a song.
Indeed, when lasers were first invented, a well meaning but WRONG physics professor claimed a laser could never heat objects hotter than the lasing material. The argument is wrong for the same reason, heating via laser is not a thermal transfer of energy.
No, I would encourage you to look in a physical chemistry handbook for potential/current plots of real world materials and how they deviate from ohm's law. The first thing you will note is that the graphs are CURVES and not even LINES!! The differences from linearity can be quite large (> 10%) and have nothing to do with experimental error. Some materials even have current *decrease* as applied potential increases. Anyway, the relationship is a much more complicated function for even near-linear materials. There are also more variables involved - a real world material has its resistance change with temperature and pressure, for example.
Ohm's law (and many other laws in linear equation forms) are really just the first term of a Taylor's series expansion of a polynomial approximation, nothing more.
Or to take chemistry as an example, do you really think one mole of oxygen gas and two moles of hydrogen will combine to produce one mole of water? No, in the real world some of the gasses will not react at all, and some hydrogen peroxide (and even higher order oxides) will be produced. So 02 + 2H2 -> 2H20 is an approximation too.
actually, most scientific "laws" are approximations - for example, no real world material obeys Ohm's Law exactly, Boyle's law applies to no real world gas, etc. The difference between hypothesis, theory, and law is vague. As for the laws of thermodynamics, we don't even know if our universe is a closed or open system.....the laws are USEFUL, but are not TRUE in the absolute sense.
I'm amazed at how many people think wealth is a finite sized pie that gets cut into thinner and thinner slices. Wealth can be created and value added to products and services...these poor countries which are taking U.S. jobs in the near term will become business partners and part of a growing world economy in the longer term. The situation is hard on the U.S. for now, but in the longer run we'll have more markets, and more suppliers. The countries which win in this process will be those that have great education, allow free thinking and innovation, and have a good infastructure to move information.
At least he didn't invite you and your friend over to his beachfront home for the weekend as houseguests so an assasin would whack you, but got whacked himself instead, so you had to carry his corpse around everywhere fooling everyone that he was still alive.....
Could lead to a Hot War also - using the advantage of the lower gravity of our moon to launch kinetic energy weapons into earth's gravity well, impacting with the power of a nuclear weapon with none of the pesky radiation or need for exotic isotopes.
lead to gold and other transmutations have been done since the mid-20th century. Just takes a garden variety proton or heavy ion particle accelerator with sufficient energy.
Atoms can and have been be created, copied and destroyed.
well, in a huge project with dozens of developers coming and going, and hundreds of classes this kind of thing will help alot...especially since a bad cast is a show-stopper in production (code runs fine for developer and QA and first 3 months of production, then wham!)
That assumes the poor slashdotted person has console access to their server....what if it's colocated 180 miles away (like mine). Even with a 0 byte document, with 4,000 requests a second coming in, would clog the network interface of most .
But what does this have to do with resolution?
Nothing for during a single horizontal scan line, but what if an object boundary moves a "half-pixel" sideways from one frame to the next? It will be in that position in the analog display, but not in a digital one. Or how about a slightly tilted object in one frame. The boundary can be at fractional increases "pixel positions" from one scan line to the next, almost like a higher resolution display.
noise
Haha, with enough noise we can't even discern a signal
rosy-tinted ruminations of working with a soldering iron in a TV studio, old man.
Geez, is that all you've got? I would have went for "go back to taking a double-dose of viagra and heart medication and wanking off to pictures of toothless old grannies while waiting on the john for your laxative to kick in, you fossilized old fart"
yes, you have an *approx* resolution, but I'm saying with an analog system the smallest different objects that can be made aren't like digital pixels, in that their position can be moved; they aren't at a fixed location. And infinite number of colors can be specified (but how fast I can change from one to another is limited by bandwidth). And an infinite number of brightness levels can be specified with the amplitude in an analog system, but how fast that can be changed, and what brightness levels are accessible in a given time interval are limited by bandwidth.
And I do hope you grow up someday and post in a mature manner. Now drink your milk and go to bed, sonny.
no "innane crap" crap, you're just used to digital limitations. Another way to look at it, if I want to display alternating black and white in one horizontal sweep, the bandwidth does limit me to about the 450 pixels which you mentioned. However, on the next sweep, I could have all those black and white (which really would have some grey and bleeding color and other problems) moved over 0.1 "pixel widths" to the right or left, or 0.001 or 0.0001 pixel widths (bandwidth does NOT constrain such things). I can also modulate the carrier to 90% of peak (for a grey level), or 89.9 or 89.88 or whatever, bandwidth doesn't limit me there either (though it DOES limit how fast I can modulate, how fast I can make changes)
By the way, I was a technician in a television studio building video switching equipment and related gear in 1979-1982, and I also hold a B.S. in engineering physics specializing in EE. Plus designed and built my own AM, FM and PM raido equipment as ham hobby
So someone here is spouting off at something they know little about, but it sure isn't an old analog electronics hand like me.

that's correct, because I calculate 7,043,226,811,195,519,665,176.9 grains of sand on earth. Finding that 0.9 of a grain was a bitch, though
