    No, the "Water" example is using something simple to showcase a problem. The but about the agreements has occurred.


    MS has a history of refusing to do OEM agreements with a company if that company wants to offer more than MS Operating Systems. AFAIK they are still doing similar to this – it's one of the reasons Dell took so long to offer Linux – but now it's differences in licensing cost.

  3. Re:RF energy damage is debatable on Group Wants Wi-Fi Banned, Citing Allergy · · Score: 1

    Have to correct myself. The power of a photon is a function of it's frequency, in a linear progression in relation to Plancks Number. (E = hf where E is the energy of a photon, h is Plancks number and f is the frequency)

    In other words it takes fewer photons to make up a given power as the frequency goes up. (At 3GHz a photon has about 1.24eV of power while at 3THz a photon has about 12.4meV of power)

    So, while frequency is important, it's important because there are fewer photons, but at a higher power, in a 1THz signal than in a 1GHz signal. Interestingly, a signal from 3 to 30 terahertz is good for cooking - it's infrared radiation.

  4. Re:RF energy damage is debatable on Group Wants Wi-Fi Banned, Citing Allergy · · Score: 1

    True. But there is more power in a high-frequency signal. This is why a 2.4GHz signal at 1000 Watts creates a heating effect when a 700MHz signal at the same power doesn't. So it's natural that a signal at higher frequencies would be more damaging at lower powers.

    The fact is that these people are claiming an extreme sensitivity to a range of RF frequencies that have been in use for years. Almost every commercial alarm system in the world will trigger a radar detector - most RADAR systems run in the 2.4GHz band. Microwaves run at 2.4GHz. There are cordless phones that run at 2.4GHz (I have seen these!).

    I say test them. Put them in a trial - either like the one done in Britain to show that the "we're sensitive to cellphone mast" people were full of shit - or a true double-blind. It's almost guaranteed that you'll find that there is no statistical evidence that these people are correct.

    Yes, 2.4GHz is dangerous - if pushed to high power levels. The military and commercial RADAR systems generate a signal powerful enough to cook almost anything in under a minute. During WW2, before the advent of the microwave oven, pilots would warm themselves by standing in front of the antennas. (this is what actually led to the creation of the microwave)

    People have mentioned the danger of X-Rays and Gamma Rays and fail to see that the problem actually comes from the amount of power in them. Understand that? It's the amount of POWER behind the signal that causes the damage, not the frequency. (okay, frequency is important - at 2.4GHz the signal does resonate with water)

    According to the US Patent Office until the early twentieth century you had to provide a model or functional prototype of your device in order to receive a patent. Until the late 1970's/early 1980's a patent could only cover a physical device.

    That is exactly what the patent system was designed to cover. Processes were added at some point, though I'm not exactly certain when, and almost assuredly because of businesses. Writings, data and artwork were to be covered solely by copyrights.

    (Not a quote, but I had to set this aside somehow...)

    If I begin working on an operating system that is multi-threaded, uses multiple processors and such, there are very few methods of having shared data structures safely. The safest and most efficient would be to read the data, make a copy of it that isn't shared, work on the copy, then update the shared original from the copy. This is extremely obvious and almost anyone would arrive at the same conclusion given the same requirements.

    However, it is patented. It's the "RCU" - or "Read, Copy, Update" - method of safely having pools of shared data in a multi-threaded environment. If I implemented it I could be sued over the patent violation. It doesn't matter that I have never seen or read the patent. It doesn't matter that the system seemed painfully obvious to me. What matters is that it wasn't obvious to the people at the US Patent and Trademark Office.

    My example above isn't to show that all software patents are bad. What it's doing is showing that the USPTO (and presumably other countries patent offices) need to start using people who understand the field that the patent is in. If you try to patent something like the RCU method, it goes to someone who has experience with programming. If it is a patent on a firearm, it goes to someone with experience as a gunsmith (or similar).

    That alone - using a person or group with experience in the field that the patent applies to to examine the patent and make sure it's 100% valid before granting it - should cut down on the number of bogus patents. Truthfully, there should also be limits placed on what can be "claimed" by a patent - to stop someone from patenting a never-produced design for something and then suing when someone produces something that is only marginally related.

  8. Re:hysterical on Taser International Wins Lawsuit to Change Cause of Death · · Score: 1

    Umm... hell no. You're completely and utterly wrong. The point of the taser is to offer a non-lethal alternative to the gun in cases where it is safe for the officer to use it instead. That fact that it turned out not to be entirely non-lethal is the concern here. You'll not find any police departments even remotely considering having their officers carry tasers instead of guns because that would be ridiculously unsafe for them.

    Incorrect. The TASER is not "non-lethal", because anything could be lethal in the proper circumstances. In this case the correct term is "less than lethal" - because when used properly and the target doesn't have a pre-existing condition that can be triggered by it - the TASER will not kill.

    Note that "less than lethal" is also used to describe things like Rubber Bullets and bean-bag rounds. Neither is designed to be lethal, but if you hit someone in the right place and they are at the right range, they will die.

    This applies to the TASER. If you have a heart condition (or just a weak heart) being hit with the voltage from a TASER can cause a heart-attack. But then, an old-fashioned, hand-held stun gun would do the same thing if it was used to hit someone near the heart.

    This is the problem with the GPL and LGPL - no matter how many times you #include a file that contains interface information for a GPL'd library you aren't creating a derivative. It doesn't matter one bit that the final output contains things carried over from those header files - because #include is acted on by a mechanical translation mechanism. Under US and *MOST* other nations copyright laws, a mechanical translation cannot hold a separate copyright from the original. What this means is that you can write an application that uses Qt, Gnome, etc... and release it under your own license - with no requirement to distribute the source code to the application. It doesn't affect the license on the libraries - you will still be bound by the license on them - but... Basically what it means is that the LGPL and the "Bison Exception" were never needed.

    2) Yes, of course. But what I'm saying is that I've never heard of a processor flaw where a faulty instruction would reveal part of the data being worked on. Yes, a processor can have problems with instructions - the original Pentiums had a nasty one in the FPU's lookup tables and then there is the venerable F00F bug - but the FPU bug affected certain calculations and the F00F bug caused the processor to lock or triggered a system reboot. Neither one revealed data.

    1) It's not clear that the ECC PRNG is "backdoored" - everything I've seen says that it "may" or "might" have a weakness where there is a second, related set of numbers - not that there IS a second set of numbers.

    2) This article doesn't say anything new. If a processor has a flaw in its math processing then exploiting that flaw could lead to any result - but it's unlikely that it'd just cause the processor to kill the security software. Look at the F00F bug on older Intel chips - it caused the processor to fault and lockup. So a processor fault causing a single process on a system to fault seems like a non-starter.

    3) Almost all modern processors actually "decode" a single instruction (like movb %ah, %al) into a series of very low-level instructions. Intel has actually built a way to update this translation process into its newer processors - the "microcode update" system. On Linux and Windows, at least, you can install a new version of the microcode on a processor.* This process could be co-opted by someone with the proper resources to cause a processor to mis-function.

    *I think the reason they don't offer things like SSE3 as a microcode update has more to do with economics than limitations of the silicon

The OpenBSD folks shouted me down, yelling that "I didn't care about the truth" and that the changes were "mere adaptation not deserving their own copyright". When presented with facts to the contrary they got real quiet and the thread died.

    So I'm guessing that Theo (at least - Reyk strikes me as much more intelligent and open to the truth) won't accept this examination. He has, at least once, very vocally accused the FSF of backing Moglen setting up the SFLC as a move to "infect" all code with the GPL. With that viewpoint in mind - the paranoid, FSF is out to get me viewpoint - I can deduce that Theo's response will be "Lawsuit! The SFLC is an arm of the FSF and Linux! Our code is being stolen!".

    Of course, with the re-licensing of the once GPL(v2) only changes under the ISC license (and with the SFLC's review of the code), I can't see any lawsuit being successful. Strangely, I don't expect Theo to understand this, as he doesn't seem to understand anything else.
