God, I like how you think, even if we are on different sides of the T(H)GSB fence.
What he is talking about folks, is the bigger the counterweight, The bigger payload your space elevator could carry, without needing a thicker teather toward the top. Also it enables construction by lowering strings from orbit, because there is something nice sized in orbit to teather to. This is especially important for the first strand, that will be too weak initially to support any weight at all, and certainly not the weight of an entire other strand.
I fully agree, but since an asteroid's orbit cannot be accurately predicted to "earth hit or miss" accuracy greater than about 20 years in advance, that little nudge may be the nudge that causes the asteroid to hit instead of miss. Strapping one of these magnetic bubble solar sails would alter an asteroid's orbit so drasticly, even on late notice, and be steerable to boot, that they make painting the surface white pale by comparison (pardon the pun).
Same theory, more active approach and to paint it would still require a launch, intercept, and application of device, be it paint or a giant magnetic field. The best part is a system like this could be used to steer an earth crosser into earth orbit, providing plenty of zero G raw materials for future missions.
Perfect transaction security, privacy, and accountability.
When you are on a first name basis with The UPS driver, Fed Ex Driver, The alternate UPS Driver, The alternate Fed EX driver, The women who sound like they could rock your world from both UPS and Fed EX customer support, you decided to pave and widen your driveway just so the UPS truck would really deliver to your door, you opened up a secured visa online account to insure against shady vendors and the list of orders you are tracking requires it's own automated database that only delivers summaries of what is supposed to get here today and what needs your personal attention because it is over a week late, you really need to simplify your life.
If predicting the trajectory of an asteroid's orbit is so heavily dependent on surface reflectivity, how do we know the change we make will not bring it closer to earth and not farther away? I liken it to our ability to change the weather, but not predict the weather.
I would prefer to make the trajectory change closer to the impact event so that we could more accurately predict the results.
Unlike Apple's current OS, which runs on x86, a platform they don't even sell.

Sun must compete with SGI, HP, Compaq, and IBM for that market share. If you want Linux you do not have to buy Sun. If you want OS X, YOU MUST BUY APPLE. If I want big iron, I can get Sparc, Alpha, Mips, Itanium and even Power4 from IBM
"For what it's worth, everyone in the industry knows that they cancelled the clones because Apple lost major market share to them"
Why did they lose market share to them? Come on, think man. They lost market share because the clone makers were producing equivalent hardware, albeit less stable (probably because of intentional documentation errors in Apple's specs), at half Apple's price.
To quote the other asshole, "Developers developers, Developers, Developers". Microsoft open sources a piece of code to attract colleges that generate Developers for their platform. Fucking computer games have turned into a 9 billion dollar a year industry, as big an industry as the motion picture industry for god's sake. And Microsoft made a play for the whole ball of wax by releasing X-Box. They hoped to snare Developers from competing consoles, making them realize developing for x-box meant an easy port to the PC. They hoped all the existing Direct X developers would develop for X-box exclusively so they could take a bigger cut of the games market. How does their cut get bigger? They OWN THE FUCKING HARDWARE. Develop for X-Box and not PC and Microsoft gets a bigger cut of the 9 Billion dollar pie. X-Box II will not include nVidia or Intel. They are going to try to do the damn thing in house.
They learned that little lesson from APPLE just like everything else.
So, Apple is stealing GPL developers. How obvious is it? How about a fucking contest to port apps over to Apple! How often have YOU switched development platforms? IT'S A BIG THING. Apple is stealing our intelligence pool. The worst thing is everyone here believes their BULLSHIT. sheep led to slaughter.
Pay the fucking $1000 Apple TAX for their inferior crap hardware. Don't fucking buy into the GPL and then choose CLOSED HARDWARE. We might all own the software and share it as we like, but if the software will only run on ONE HARDWARE VENDORS CRAP, we OWN JACK SHIT.
Sun holds no pretenses that they are an OSS vendor. Apple with their "Think Different" campaign and singing OSS/Linux love balads are portraying themselves as our friends. But no matter what we port over or write, Apple still has complete control over their own hardware. OS X will never run on x86, AMD 64-x86 or IA-64.
So every bit of code written for Apple, Apple owns because they own the platform. Thousands of Linux Hackers who once shunned the $100 Microsoft tax are now paying another tax:
$2000 for a new system that should cost $600. $300 for memory that should cost $100. $1000 for a flat panel that should cost $600.
Apple is sucking money and time out of the OSS software movement that we will never get back. Linux may die because there is no one left to develop for it except the people who do it for purely philosophical reasons.
The dream of Open Software on Open Hardware will die at the hands of Apple, Who owns their Platform and is a jealous (litigous) god. Remember the clones. Check Apples current specs against the old clones. Look at the advancements the PC has made in the same time. What you will find is two years of stagnation. This might change, but without competition on the platform, it is extremely unlikely.
So, because you have used the same password for everything, Microsoft has the passwords for every one of your computers, and hotmail/passport has been compromised several times, even assuming Microsoft is trustworthy themselves, which based on their business practices, they are not. I am telling you as a friend, use a better password scheme.
Seems like the technology required to find planets will be in the reach of amateurs soon. So there will be many more "eyes" looking for planets. Or the technology is becoming sufficiently mature that we will be able to detect smaller rocky bodies. Or he is about to launch a distributed computing project to analyze the visible signatures of every visible star for the wobble caused by planet motion.
Right now, we could not detect our solar systems planets. There are 9 planets exerting their own oscillation into the sun's wobble. Perhaps he cannot do it now, but he knows what it would take to get there. Two years ago we all laughed and joked about IBM's process that would allow 5ghz machines. We all said "whatever, how the hell do they know, vaporware" Now we have seen 5 Ghz machines demonstrated, overclockers are hitting 3 Ghz easily and you should try not to discredit a geek in his field if you are out of yours.
You spoke true when you refered to apple, the horse I am beating as "dead". Mac died when it hit less than 10% of the market. OS X and the G4 iMac is just a hollow company rallying its zealots. Very similar to Enron's actions before they were exposed as frauds. Apple is dead. I'm just kicking it's corpse.
If you can't make it fast, make it pretty. Miata has done rather well. Perhaps Apple may yet survive.
How insightful. Just because it has been said a thousand times and you don't like it, does not make it untrue. It just makes you a fool, which is your real qualm with those of us who speak the truth.
But unfortunately, it is not OSS for the masses. This is not a strong argument for OSS over Proprietary methods. Apple is not the "Think Different" OSS solution. Contrary to their hard marketed image, they are the most closed company of all. They own the hardware AND the software. Shure, they use FreeBSD but so does Microsoft in their TCP/IP stack.
It is unfortunate that so many true OSS Developers have begun effectivly working for Apple for free.
The OSS Community will never see a scrap of benefit from Apple.

can we assume that the sun just puts out a given ammount of energy that only fluctuates a little bit and on long timescales? so, while the sun maintains the temperature, humans create all kinds of changes that warm the planet.
But in any case it doesn't really matter: if changes in the Sun's dynamics are making the Earth hotter, it will suck just that much more when we add insult to injury.
"To imagine that we have had no impact on global warming is obviously false."
Here we disagree:
Artificial heating locally will quickly re-equilibrate with the natural observed heat profile.
The facts in the Bible will quickly re-equilibrate with the facts of the Bible.
Do you have an independent observational verification of temperature gradients that is not full of corrupt data also? If so, why do we care about 614 holes that are all similarly flawed? The experiment is self-consistent but that does not prove that it is factually consistent.
Our difference is that I will not let my opinion on the subject of global warming bias my interpretation of the data or accept experiments that cannot comply with scientific method even if they support my opinion.
If you have ever spent any time standing in hot drilling mud, you would know that the thermal impact of drilling a hole is amazing. If a hole requires a 3500 hp V12 detroit diesel to run for 3 months, nearly 90% of that mechanical energy is converted to heat inside the hole. Additionally, the steel casing conducts heat 6 times better than, for instance, basalt and will smooth measured temperature gradients enough to make any data meaningless.
Let me put it into physics terms for you, since that is your field. The observer affects the observed. In the case of measuring the temperature of bore holes, the observer has had such a vast impact on what the observer is measuring, that all the data is irreversibly corrupt.
Yes, global warming exists and is primarily caused by humans. But this data, while supporting that fact, is corrupt, and therefore must be ignored. The experiment as conceived is flawed.
Drilling a hole generates heat. Sometimes harder substances generate more heat, sometimes less. While the "heat tree rings" may exist, as seems logical, the act of attempting to observe them corrupts your data.
Using extremely old holes could mitigate this somewhat, but then you have no measure of the geological composition, and therefore thermal properties, of the rock the hole was bored through.
This makes any measurements made of core earth temperature so speculative as to be worthless, except as a very "scientific" expensive way to spread fud. There are quit a few "scientific" methods to measure global warming that are in fact just pseudo scientific pawns in the politically charged arena of environmentalism.
To imagine that we have had no impact on global warming is obviously false. Any argument contrary to what should be painfully obvious to the most casual observer is pure political bullshit.

The automatic gain control on the low noise amplifier in the receive section of the card would shut down the receive path for any card inside the structure where the 100 watt omni is located. Think of when you yell into a mike and it cuts out to protect itself. So, you could provide strong signal to everyone, unless they were too close to you.
And as the article mentioned, this applies to Packet Radio, which by it's nature has a single source and a single destination. Omni directional antennas are used primarily for point to multipoint communication not point to point as is typically used for packet radio.
Also, remember the inverse square law when designing your network. Putting more power into your transmitter does less to improve communications performance at a distance than a properly designed antenna. High gain omni directional antennas are more efficient at propagating your signal than increasing your power to 100w.
For instance, a 15 dBi High Performance Omni sold here for $209.95 increases the effective radiated power by a factor of 100,000. A factor of 10 for every 3 db of gain. So, your standard 100mw transmitter would transmit less power than the 100w transmitter initially, but would fall off less with distance, surpassing the performance of a 100w transmitter on a standard antenna after the first few feet.
The other route is to use a 2.4 Ghz Klystron like this that costs in the neighborhood of $30,000 which of course can be coupled with an high gain antenna, which will not survive long at its maximum rated load.
This is not a competition of Penis sizes or "My athlon is faster than your Intel boxen" this is a game of finesse where the sharpest mind and the most efficient system dominates through signal quality, not signal quantity.
You get Mary on her 2.4 phone and the Muni Hospital complaining about you ruining ther gossip chat and emergency beeper service and you won't just loose you expensive 'leet 2.4 Ghz gear, you will do prison time for willfully jamming vital communications services, tantamount to a terrorist act, post 911.
Want to be 'leet? Implement a flat panel phased array with electronic beam steering to pinpoint your distant end receiver at gain levels limited only by the precision of the real time clock you use to gate the injection of the 0-180 and 180-360 phases of your waveform.
That would cover as many stations as you wanted, within the limits of line of sight. You could go back to college to learn the RF theory necessary to build such a device for the price of a big dumb klystron and go on to dominate the mobile gigabit bandwidth telecommunications arena. Perhaps your choice is clear.
'cept you have to compete with me, and I'm 11 years ahead of you:)

The automatic gain control on the low noise amplifier in the receive section of the card would shut down the receive path for any card inside the structure where the 100 watt omni is located. Think of when you yell into a mike and it cuts out to protect itself. So, you could provide strong signal to everyone, unless they were too close to you.
:)
And as the article mentioned, this applies to Packet Radio, which by it's nature has a single source and a single destination. Omni directional antennas are used primarily for point to multipoint communication not point to point as is typically used for packet radio.
Also, remember the inverse square law when designing your network. Putting more power into your transmitter does less to improve communications performance at a distance than a properly designed antenna. High gain omni directional antennas are more efficient at propagating your signal than increasing your power to 100w.
For instance, a 15 dBi High Performance Omni sold here for $209.95 increases the effective radiated power by a factor of 100,000. A factor of 10 for every 3 db of gain. So, your standard 100mw transmitter would transmit less power than the 100w transmitter initially, but would fall off less with distance, surpassing the performance of a 100w transmitter on a standard antenna after the first few feet.
The other route is to use a 2.4 Ghz Klystron like this that costs in the neighborhood of $30,000 which of course can be coupled with an high gain antenna, which will not survive long at its maximum rated load.
This is not a competition of Penis sizes or "My athlon is faster than your Intel boxen" this is a game of finesse where the sharpest mind and the most efficient system dominates through signal quality, not signal quantity.
You get Mary on her 2.4 phone and the Muni Hospital complaining about you ruining ther gossip chat and emergency beeper service and you won't just loose you expensive 'leet 2.4 Ghz gear, you will do prison time for willfully jamming vital communications services, tantamount to a terrorist act, post 911.
Want to be 'leet? Implement a flat panel phased array with electronic beam steering to pinpoint your distant end receiver at gain levels limited only by the precision of the real time clock you use to gate the injection of the 0-180 and 180-360 phases of your waveform.
That would cover as many stations as you wanted, within the limits of line of sight. You could go back to college to learn the RF theory necessary to build such a device for the price of a big dumb klystron and go on to dominate the mobile gigabit bandwidth telecommunications arena. Perhaps your choice is clear.
'cept you have to compete with me, and I'm 11 years ahead of you
