You have the Part 15 and ISM services for that. You really can buy a microwave link that's metropolitan-distance and legal to use.

We lost much of our 440 capability to PAVE PAWS in California. Remember, Amateur Radio is not the primary service on many bands. The military is on 440.

If you want that nearly infinite microwave spectrum, you have the Part 15 and ISM services. Absolutely nothing is stopping you. Power is not the issue with those frequencies, it's line of sight and Fresnel zones.

No, I absolutely do not have to prefix my words with anything. You do that by posting as an anonymous coward. I use my real name to indicate that I stand behind my words.

Not only does email provide a paper trail of the discussion, it doesn't require that someone drop everything they're doing right now just to answer a couple of questions.

I HATE messaging systems, phone calls, and personal conversations for just that reason. I used to have one guy at my last job who constantly came to ask me questions instead of using Google or reading the documentation I'd already sent him. Laziest bugger I've ever had the misfortune of working with... and a smarmy arse-kisser to boot, which annoyed the schite out of me.

If they want a real test, try Orlando, Florida. I found it the most trying city to drive in of any I've ever lived in, thanks to the joyous combination of people visiting from Ohio that expect a mile clear ahead of them and people from New York who think 6 inches is enough of a gap for someone to cut them off.

How can you compare a business that has only two real products (Firefox and Thunderbird) to a company that had several iterations of hardware and dozens of software products, as well as service, support, and contracting arms?

Of course Mozilla is on the downslide -- Chrome came along to compete with them, and Internet Explorer was improved, while Safari came into existence. Mozilla still make my browser and email clients of choice, but not all people make the same choice.

And so it should be.

But while Mozilla may be waning in popularity and market share, they are hardly imploding like Sun did. They were never any where near as big nor as important to the industry to begin with!

Driver sub-system specific frameworks and further more generic services and data-structures

VMware can implement all the data structures, generic service definitions, and frameworks they want, such as having the same function names, and struct files, the "Headers", without necessarily having to copy the executable code that is defined in those frameworks.

The software program is subject to copyright. The use or re-implementation of interfaces to a software program are considered fair use, and it's an important concept behind open source, that the interfaces when different packages talk to each other allow drop-in replacement of one program for another, such as a new open source software program to control your proprietary piece of hardware.

These function prototypes, struct formats, and interface definitions, "the headers"; are either not subject to copyright, or Linux itself and many GNU projects would be in deep trouble, because in the Linux world copying structs and headers from proprietary software is a common practice, that actually is part of what allows GNU to even exist.

So if they made that argument in court that the frameworks are subject to copyright, it would also be a major setback for many open source software projects such as Wine, or even various GCC projects.

And the Linux kernel as well.... if the Linux kernel struct formats and headers were subject to copyrights, then struct formats used to control hardware would be as well, and Microsoft could sue Linux developers over making a driver for hardware device X that used a struct for control based on a Microsoft copyrighted standard.

Also, SCO probably should have won if this was the case, and since POSIX itself is copyrighted, and header files in many BSD-related OSes include fundamental interface definitions that are copyrighted with no license to use.....

If the two of us ever get into a fight to the death, I'll gladly be the loser walking away.

This.

And Mr. "There is no winnable war" needs to re-examine even some recent history. Does he really think that reborn, modern economies like Germany's represent the outcome of a war not won by those who reacted to that country's earlier aggression? Does he really think that the communists now running Vietnam didn't win their conflict? Does he really think that the rebels in the American colonies didn't win their war with the British crown?

Gaseous platitudes about such things made in an attempt to wish away groups like ISIS (if we just say that wars can't be won, they'll stop lopping off people's heads, right?) are ridiculous. War is horrible, but they can and have been won. Ask the Imperial Japanese Navy.

It's just not the immediate end of the world as they may view it, but is being more sensitive to such things being crazy?

Their claims are what identify them as crazy.

From the summary:

Today, Lumsdaine views the thread connecting GPS and drones as part of a longer-term movement by military powers toward automated systems and compared today's conditions to the opening sequence of Terminator 2, where Sarah Connor laments that the survivors of Skynet's nuclear apocalypse "lived only to face a new nightmare: the war against the machines."

When they start comparing reality to sci-fi apocalypse movies then there is a problem.

And when they start destroying things because of it, they've gone into "crazy" territory.

How Activists Tried To Destroy GPS With Axes 228

Posted by samzenpus
from the here's-johnny dept.
HughPickens.com writes Ingrid Burrington writes in The Atlantic about a little-remembered incident that occurred in 1992 when activists Keith Kjoller and Peter Lumsdaine snuck into a Rockwell International facility in Seal Beach, California and in what they called an "act of conscience" used wood-splitting axes to break into two clean rooms containing nine satellites being built for the US government. Lumsdaine took his axe to one of the satellites, hitting it over 60 times. The Brigade's target was the Navigation Satellite Timing And Ranging (NAVSTAR) Program and the Global Positioning System (GPS). Both men belonged to the Lockheed Action Collective, a protest group that staged demonstrations and blockaded the entrance at the Lockheed Missiles & Space Co. test base in Santa Cruz in 1990. They said they intentionally took axes to the $50-million Navstar Global Position System satellite to bring the public's attention to what they termed the government's attempt to control the world through modern technology. "I had to slow the deployment of this system (which) makes conventional warfare much more lethal and nuclear war winnable in the eyes of some," an emotional Kjoller told the judge before receiving an 18-month sentence. "It's something that I couldn't let go by. I tried to do what was right rather than what was convenient."

Burrington recently contacted Lumsdaine to learn more about the Brigade and Lumsdaine expresses no regrets for his actions. Even if the technology has more and more civilian uses, Lumsdaine says, GPS remains "military in its origins, military in its goals, military in its development and [is still] controlled by the military." Today, Lumsdaine views the thread connecting GPS and drones as part of a longer-term movement by military powers toward automated systems and compared today's conditions to the opening sequence of Terminator 2, where Sarah Connor laments that the survivors of Skynet's nuclear apocalypse "lived only to face a new nightmare: the war against the machines." "I think in a general way people need to look for those psychological, spiritual, cultural, logistical, technological weak points and leverage points and push hard there," says Lumsdaine. "It is so easy for all of us as human beings to take a deep breath and step aside and not face how very serious the situation is, because it's very unpleasant to look at the effort and potential consequences of challenging the powers that be. But the only thing higher than the cost of resistance is the cost of not resisting."

Comment: Re:Global Warming Wiped Out Mars? (Score -1) 57

I think they are confusing wind erosion with water erosion. Moisture gets absorbed in rocks even in vacuum - probably the Moon might have some crystal water in some silicates too - , but Mars probably never had a temperature/gravity pressure to sustain liquid water on the surface, unless solar output was much different. The atmosphere is extremely thin, but because of low gravity, 1/3 of Earth's dust flies up easier too. Otherwise the temperature/pressure is probably at the solid/gas transition. Here, the pressure ranges from 0.0044 psi(0.003 atm) on Olympus Mons's peak to over 0.1675 psi (0.011 atm) in the depths of Hellas Planitia, so it's between 0.3% and 1.1% of the atmospheric pressure we have on Earth. The triple point of water is 0 degrees C (more like 0.01) and 0.006 atm, or 0.6% of that on Earth. So in theory, there might have been liquid water extremely close to the triple point, but the temperature would have to be above 0 (which is probably rare) and under 20C or so (under room temperature.) Just cuz you could have a puddle of liquid water physically existing in the open atmosphere of Mars, it does not mean that it would not evaporate away super fast, as even iced over frozen clothes hung out to dry in the winter eventually dry even under the freezing point in the sun (and you have to be careful not to break your jeans or underwear when frozen and brittle, they are very fragile), so a puddle of liquid water would evaporate very fast unless the atmosphere is at 100% humidity or close to it, under such pressure, and then once in the atmosphere, the gravity of Mars is so weak that it would easily reach terminal velocity and escape. And you can tell that it would, from the atmospheric composition of Mars which is 96% CO2 at molecular weight 44, 1.9% Argon, 1.9% Nitrogen, and traces of oxygen, carbon monoxide, methane, water, etc. Molecular weight of water is 18, and much lighter than 28 for nitrogen and 32 for oxygen or 44 for CO2. Planets with cold enough surface and high enough gravity capture hydrogen too from the solar wind, including all the gas giants like Jupiter, Neptune, Saturn and Uranus, with a molecular weight of 2, but Mars is too weak gravitationally to go as low as 18, and Venus is too hot to go as low as 18, and they boil off hydrogen at 2, water at 18, nitrogen at 28, oxygen at 32, and only have CO2 and H2SO4 and the like remaining in the leftover distillate, while Jupiter boils off nothing, but earth boils off hydrogen at 2, helium at weight 4, but does not boil off methane at 16, water at 18, nor nitrogen 28, oxygen at 32, etc. So liquid water does not exist on Mars under present circumstances because it boils off fast from the surface pond and then boils off fast from the atmosphere into outer space. If in the past the temperature were colder, by ether lower solar output (like ice age on earth), or by Mars being in a farther away orbit, and then getting knocked closer by something else, but farther away it was just the proper amount of cold to hold water on its surface atmosphere, at least you could have had a saturated water vapor atmosphere on Mars, but it might have been under zero celsius, to where yes, you have water, but it's all ice, like at the poles, and never liquid, simply because Mars lacks the gravity to hold it in the atmosphere under enough pressure where it can stay there over 0 degrees required by liquid water, otherwise the only water on Mars is in the solid/gas transition range in the graph below: http://www.sv.vt.edu/classes/M...
I think they are confusing wind erosion with water erosion, or maybe ice/glacier erosion remotely possible if you fly off on a tangent of coincidences and luck, but never liquid water. Mars is too small for water. Venus is a whole lot of different story, about the same size as Earth, and all it would need to get life on it pronto is that at its Lagrange point it needs to wear some huge ass shades to be cool.
