  1. Re:Let it go Louie on Debian Struggling With Security · · Score: 1

    You are right, of course. Debian went too long between releases, and didn't provide the social means to correct the situation. That left an opening. However, one can fault the Ubuntu crowd for taking advantage of the situation instead of fixing Debian. Especially since they are doing it for profit on the backs of the remaining Debian packagers. Well, let's see what happens :-)

    To say nothing of the fact that Ubuntu raided many key developers from Debian, which is now left scraping for help. Ubuntu is slightly repackaging the work of the real packagers, the Debian people, and calling it a new distro. It's basically a hostile fork, and we are the worse for it.

    You are not accelerating in either case. You are following a spacetime geodesic.

    However, when you lie on your back on the floor on earth, the upwards force of the floor is causing you to deviate from a geodesic, and you sense that as an acceleration, i.e. your weight. Now hold a ping pong ball above your nose and let go. It follows a zero g geodesic, but shortly will collide with your accelerating nose.

    By 'postulate' Einstein means, "Assume that future experimentation will show that light travels at c wrt any inertial observer, and physics is the same for him." So the answer to "...how come the light ray [doesn't move] with 1.5 c from the resting observer" is simply that experiment shows that it doesn't. Yes, that's not what you might expect from experiments throwing rocks from trains, etc.

    But in the case of light, if you can carefully observe what is going on when the moving physicist makes his measurement of c, you will find that he gets the value he does because his clocks are running slow compared to yours.

    The classic thought experiment here is a 'light clock', with light bouncing between two mirrors. What is the path of the light in the moving clock as seen by the stationary observer, and what does that mean to the rate of the moving clock compared to the rate of an identical stationary clock?

    "Individual contributors to the Linux kernel gain access to the full resources of the Open Source Legal Defense Fund including guidance on how to best protect and defend their own intellectual property rights. They also receive $25,000 in legal protection from OSRM if they are named in future lawsuits involving their contributions to the Linux kernel. Membership for individuals is $250 annually."

    First, it seems to me that the Linux kernel developers should be getting this protection gratis from OSRM and the companies which are actually making a profit from the developer's efforts, and which would not exist except for the efforts of the developers. No, let's charge the kernel developers each $250 annually!!

    Second, $25,000 isn't going to go very far if you get sued.

    Third, the coverage cost seeems exorbidant. 1% per year for a risk that everyone has been saying all these months is non-existant! I have a $1 million liability umbrella which costs me not 1%, not 0.1%, but about 1/3 of 0.1%.

    And if you're a company you pay only 3%! Then there's the Seminars, offered nationally, that you get to attend (at additional cost, no doubt). They don't say whether the coverage includes anything beyond the SCO issues.

  13. Re:I'm no mechanic, but... on Technology Makes New Cars Too Expensive to Fix · · Score: 1
    Some of the replies claim that HD lights are not a problem if properly "filtered and aimed". However, unless your car is equipped with a load-leveling suspension, adding weight in back (luggage or trailer) is going to raise the beam angle. Modern lights have a very sharp cut-off and must be aimed correctly to avoid dazzling on-coming cars. How many people go to the bother of doing this after they load up for a trip? Also, when two cars meet coming over hills, the beams are noticeably tilted upwards and rather blinding.

    You can't depend on even the dealers to get aiming correct. I had mine done recently, and it's pretty clear to me that now they are too high, even the low beams illuminate the trees. I must be blinding people now. It's not true that these lights are no brighter than the older styles. Just drive a car equipped with them.

    It doesn't just read like an apology, it is an apology. Lessig states he misread the court and argued poorly. However, IMO the majority opinion was one of pragmatism (just another extension), a desire to "harmonize" with the EU's extension, and the belief that since Congress had been given the authority to set the limits, the Court should not intervene. The dissenting opinions by Stevens and Breyer are remarkable. They actually addressed the constitutional issues.

  17. Microsoft Proposal is Spam Friendly, Like CANSPAM on Gates on Spam · · Score: 2, Informative

    Here's what I get from the MS docs:

    Four categories:

    1. Zombie Windows PC attempts SMTP with recipient MTA. Latter looks up published IPs (as XML in DNS "text" field) for "responsible" sender's domain MTA, finds the sender isn't one of these, drops the session.

    2. Large ISP's MTA attempts SMTP with recipient MTA. Sender IP verifies. Recipient MTA looks up *certificate* of ISP and verifies it. Email delivered.

    3. Small domain MTA attempts SMTP with recipient MTA. IP verifies, but there is no certificate. Recipient MTA asks sender *MTA* (not necessarily PC of originator) to factor a medium sized prime, or some such. Good sender solves problem, spam sender disconnects.

    4. Roaming laptops, mail forwarders, anonymous remailers, etc. These are more problematic, but are handled by adding headers which identify the original responsible sender.

    Problem: The Independent Email Certifying Authority. These verify that the large organization is following "proper email policies". But you can bet that these policies will be something rather consistent with the CAN SPAM act. In other words, you are still going to get a lot of "legal" spam.

    Finally, MS will grant anyone a reciprocal license to use, modify, distribute, etc. *except* everyone must get their own license. So it appears at some point in time MS can start charging for the license, or bundling it, or whatever. The early adopters will still have good licenses, but MS can use the code they developed, put it in Windows, and then limit new use of the patented technology to the Windows platform.

  19. Patriot is Abusing a Decent Patent on Five PC Vendors Face Patent Lawsuit · · Score: 1

    Chuck Moore is one of the two inventors. Chuck is the inventor of Forth, and has devoted the last 30 years or so to devising Forth microprocessors. He is still at it. Although unfortunately he has been surrounded by kooks most of his career, he is a visionary and a very serious guy. Most of what he has accomplished goes against the grain of both the hardware and software industries, so he never got much respect and has collected a bunch of dopey followers.

    I don't know if Chuck has any residual financial interest in Patriot. I suspect not. But if he did get something out of this that would be great, because he's a real inventor and he deserves it.

    This patent describes a Forth micro which incorporates a variable speed clock. The clock is implemented using a ring oscillator, and doesn't use an external frequency reference such as a crystal. The clock rate varies continuously depending on the temperature, voltage, and even the quality of the process used to fab the particular chip. Thus it gets the maximum available performance out of the CPU/Dynamic RAM combination which is implemented on that one chip. If the alleged infringers are using this technique in their embedded micros, then Patriot may have a case.

    The patent is a division of one filed in 1989 and appears to be a decent patent. The problem with the guys at Patriot is that they are claiming far more than what is actually granted. The patent does not claim the ablility to run a CPU at various clock speeds, or to run the CPU at some multiple of the main memory.
