  1. Re:Lawyer: clearly correct under U.S. trademark la on Victory for small business in domain disputes · · Score: 1
    Somehow, Hasbro has gotten the idea that trademarks reach *much* farther in domain names than they do anywhere else. This is simply fallacious, and worthy of sanctions.

    Yes. Hasbro's attitude in this case was rumored to be "we want clue.com, we don't think you are infringing on our trademark, but NSI's dispute policy lets us beat up on you, so fork it over." Which is clearly WRONG.

    It is an excellent day for Right over Might.

  2. Re:GPL-compatible? on Berkeley removes Advertising Clause · · Score: 2
    So, now that the advertising clause is gone, does this mean that FreeBSD can simply tack the GPL onto the existing license?

    NO. It doesn't mean that. It is not desirable for FreeBSD to change to the GPL, and that will never happen. Trust me on this. And you can't just tack on the license. It just doesn't work that way. Berkeley still owns the copyright to many files so FreeBSD could not change things like that. If any of the Linux people think they can just "tack the GPL on" to the file, they are flat wrong, plain and simple. Licensing terms are controlled exclusively by the copyright holder.

    Many people use FreeBSD specifically because it has a proprietary friendly license. One company I know if actively modifies the kernel to get the best performance they can out of their video hardware. And the do not want to make all of those changes available. Many aren't relevant to a general purpose OS, and some document interfaces to their priorietary system. The GPL has to much ambiguity to base a business plan on. Linus Torvalds says it means one think while RMS says it means another.

    No. FreeBSD will never be GPL'd.

Netbsd/hpcmips is complete enough that it has started the process of integrating into the NetBSD tree and should be there in the next few weeks.

    Re: Linux on the Aero, you may have problems getting enough technical data from Compaq to actually do this. It uses the slower 70MHz R3900 based MIPS processors (although I'm not sure if it uses the Phillips one, or the Toshiba one).

    MIT Xfree86 is one who did not publish anything on their use of window buffering until a bit of documentation was needed at a later date . By then someone had already patented the idea of keeping , in memory , the window that was now hidden . MIT lost that one , their failure to publish those details in the documentation resulted in that method not being considered "prior art" . This sounds strange to me. Publishing the source code *IS* considered to be publishing, so I fail to see how this could be. Also XFree86 wouldn't be the one hit with this, but rather the X Consortium and its successors.

    xdiff has done this for ages. I recall using xdiff while still in college, which would place its release in the 1987/88 time frame.

    Emacs also had a mode for resolving diffs where it would have the two "source" documents side by side with the merged document in a third window and you'd go from change to change grabbing from one or both of the "source" documents. I used this technology in 1991 and it wasn't brand new at the time. I don't think that I have the .el files which had an edit history going back into the 80's if I recall correctly. Ah, yes, here's the copy that I have's copyright notice:

    Copyright 1989, 1990, 1991 by Dale R. Worley. Do what you will with it.

    Followed shortly by the following:

    This is the documentation for version 4 of "emerge.el", an Emacs package that allows you to combine two versions of a file by selecting, for each place where they differ, which version of the difference you prefer. It is similar to Sun's "filemerge".

    I'm not sure how old filemerge is, but if this was written to emulate it, then it must go back a ways. This tickles some neurons which tell me that I used filemerge in college right after we installed SunOS 3.5 in 1986.

    After having read the patent, I think that there is enough prior art to get it tossed out if you fight it. Too bad you have to prove the patent office wrong when you get on the wrong side of these things, but that's the way it goes.

  11. Splitting hairs on Feature:GPL vs BSD · · Score: 1
    The bottom line is, the GPL is not anti-commercial or anti- capitalistic; it is only anti-proprietary.

    Much of the business world is based on proprietary ideas. Saying that it is not anti-commercial or anit-capitalistic is splitting a fine hair.

    I know of several systems that use BSD because the GPL is too restrictive and vague. Look at Whistle and Pluto. Whistle sells internet router boxes based on FreeBSD, while Pluto sells digital video servers based on FreeBSD. Both companies have bits of their system that they do not release. At the same time, both companies have contributed huge amounts of new functionality to FreeBSD. They have both said that they would be out of business if they had gone with Linux because of the GPL. It is too vague to attract investors (since the GPL has never been tested in court, no one can say for sure how it will be interpreted by the courts, which increases the risk to an investor) and too restrictive to allow these companies to maintain a competitive edge.

    How different is the CM17A from the TW523? The TW523 appears to be similar to the description that has been posted here. It uses a few signals and has tight timing requirements to talk to it. You basically have to time writes to it so that they go out on the right phase of the 60Hz signal.

    There is a good driver for the TW523 for FreeBSD. I'll have to see how hard it will be to add support for this device when my package arrives. I went ahead and ordered it, since for $6.00 you can't go wrong.

    The problem is that you cannot easily measure the
    amount of current flowing into the experiment with
    an anmeter. There will be slight losses associated with this measurement. You can account for most of them, but not all of them. You will wind up with a figure for energy put into the system, but it won't necessaryly do you any good. The energy could be stored in the form of chemical bonds or in the form of heat. The heat you can mesaure, but it is very hard to measure how much of the energy went into the creation of new chemical compounds.

    There are also small, but measurable losses due to the resistance of the wires used, the connectors used in the setup, etc.

    It is a very hard problem to measure accurately all these factors at the same time.

    Also, your reply didn't address the fundamental question of where are the nuclear by products. If it is a nuclear reaction, like Pons and Fleischmann originally claimed, then there should be by-products. Nobody to date has measured them.

    Never. In the 1000's of experiements that have been conducted since the original Utah scientists announced their findings, only a vanishingly small number have produced any amount of excess heat at all. Also, if this were a nuclear phenomenon, the researches doing the research wouldn't live long enough to report their findings. The levels of excess heat in the original utah experiments would have produced enough high energy neutrons to result in lethal radiation posioning.

    Your system is too small. Try running with multiple disks on multiple busses and you'll see a huge improvement with CAM over anything else.

    Justin Gibbs, who wrote cam, also wrote the aic7xxx driver. When it is ported to Linux, much of the error recovery is gutted because Linux's SCSI subsystem doesn't handle things as well,
    espcially in the error recovery realm. One of the things that the Pluto boxes can do is you can pull out a disk at any time and the device is dynamically removed from the system. When you hot plug it back in, it dynamically added back to the system. You just can't do that with Linux when the disks are active.

    We use the AIC chips on our pluto box (something like 12-16 of them for all the channels), so it has to be fast....

    The biggest easily identifiable things that make FreeBSD be able to handle this load are the CAM subsystem (to serve up the data fast), which Linux currently lacks. Justin Gibbs did an excellent job of getting close to the max performance out of SCSI with CAM. Linux's SCSI subsystem is primitive and slow in comparison. It lacks good error recovery and mixes too many levels of abstraction. While it does work for most people most of the time, I would doubt if it could drive the I/O subsystem as fast as FreeBSD does.

    I'm biased. I work with Justin here at Pluto, and we have Video server machines based on FreeBSD that are disk bandwidth limited. It is very fast and I'm very impressed with it.

    Purify isn't doing what VMware is doing. Purify rewrites the object code at compile time (and sometimes at runtime if you load a non purify'd file in). That is why it can do this so fast. It doesn't play any hardware games to get this speed (like some debuggers that unmap pages that for watchpoints, or try to use the limited debugging registers on some CPUs).

    They have patented the object code rewriting, but as far as I know, no one has challanged the patent. Evidently, there were published papers years before Purify reinvented (and patented) this scheme, so at least some of the Purify patents may be uninforcible because of that.

    Anyway, this has very little to do with VMWare, or how VMWare is implemented.
