    ...but we tend to not really get pure aluminum in products anyways, but still call them "aluminum". It's usually alloyed with other metals, just like iron is, to improve on some of the qualities that pure aluminum has.

    Look at newer Easton bike tubes that have scandium in them. Not a lot of it, but enough that it changes some of the mechanical properties of aluminum to the advantage for the bicycle.

    Or "titanium". Usually it's 3/2.5 Ti (Ti+vanadium+something else). Much better for most things than pure Ti. Then Lightspeed and Merlin got ahold of 6/4 Ti, which is MUCH harder and stiffer than pure Ti or 3/2.5 Ti. Of course, they can't mandrel-form the tubes (they're rolled-and-welded from sheets...) because 6/4 Ti is just too hard. But it works wonders for bike frames, and they're still called "titanium".

    We don't call glass "silica", it's just glass. Unless you're talking to a physicist, microbiologist or camera poseur...er, professional. Then they start worrying about things like "flint" glass, "fluorite" glass, etc.
    But their core material is still melted down silica, Si04. And the varieties are still called "glass", not silica.

    So if we can ignore one pedantic use of a chemical term for a different common term, then it seems equally as feasible to misappropriate another term for a different material, violating the pedantic spirit of the language once again.

    Besides, look at a bag of fertilizer. N-P-K. N is Nitrogen. OK. Truth-in-labeling momentum is conserved.

    P is for phosphorus, but the percentage listed is really the equivalant percentage of a phosphate. K is for potassium, of course, but the number is really the percent equivalance of potash, which is definitely not pure potassium, either.

    But this little violation of truth-in-advertising has been going on for, oh, at least 100 years. In fact, it's set up by law these days.

    ANFO is classified as a "low velocity" explosive. TNT is a "high velocity" explosive.

    ANFO is used in open-pit mining because its relatively low velocity explosion ends up pushing lots more material out of the way than a dynamite or other HE explosion would.

    HE is used in solid rock, where the high velocity shock helps to shatter the hard rock into smaller pieces.

    Which is why ANFO is a preferred explosive for trying to level buildings from a distance. That, and it's cheap, simple to make, and relatively stable.

    Uh, the conservation of momentum comes from the cuttlefish not pushing against the stationary water, but from the momentum of the water pushed out. Which is why jet engine power is measured in pounds of thrust (or fig Newtons), instead of horsepower (but turboprop engines ARE rated in terms of horsepower...).

    Same as a rocket. The mass of the expelled rocket fuel/combustion leftovers x the velocity they're expelled at (gained by the energy from the chemical combustion reaction) = thrust.

    Just like the thrust generated from ion drive engines.

  16. Re:Claim seems valid on Microsoft Patents sudo · · Score: 1

    ...right, this works on Win2K/WinXP, which have essentially a "super user" service running. When you do "runas", the runas command interfaces (RPC?) with this service, which can glom on Administrator priveleges onto the process if initiated successfully.

    Another way of doing it was developed as TQCRunAs, a DLL that does this differently.

    The MKSToolkit (and several other implementations) require this service to be running in order to work. This, I think, is what has been patented.

    Of course, any Unix system daemon would seem to violate this as specific cases. All MS has done is generalize the process from a user initiating a single specific protected action to using RUNAS to initiate ANY privileged task.

    the Unix-equivalent in my mind would be having a "sh" or "csh" daemon that can 'grant' SU-level privileges if properly tasked against. But, wait... isn't this what the tty system does?

    Of course, the difficulty with RUNAS is that you cannot script it, because it will always interactively prompt for password, so it is NOT usable for domain login scripts, nor is MKS' su/sudo commands (because they do things the way MSDN says you're supposed to do them).

    TQCRunAs, however, is scriptable, and does not depend on the RunAs service running. And, TQCRunAs does the same thing also for WinNT. RunAs is only for Win2K/WinXP+.

    An advert for TQCRunAs? Well, it seriously made me look cool at a previous job, so I'm a satisfied past user (deploy an IE hotfix to >1000 desktop computers "invisibly"). Compared to doing things with SMS (which would have also been an option), it was a degree of magnitude cheaper for the enterprise license for TQCRunAs, and doable in about 8 hours of VBScript programming and incorporating into domain login script, vs. waiting for the SMS people to get around to doing the job, as well as scheduling the job as a priority...

    Other neato hacks we did with it were resetting all the local Administrator passwords when user logged in, etc., from domain login script...

    As far as different, su starts a new terminal by invoking something by hitting the login daemon, right? Then, the user's operating context is that of the su'd user until the session is terminated.

    So Unix has all these service daemons that are unprivileged in and of themselves, but provide access through that barrier to non-privileged programs.

    The only difference is that MS has a specific way of writing one service daemon that allows arbitrary command execution (you can do "runas explorer" as well as "runas netpad").

    Besides, how functionally, logically different is an RPC stream verses a Unix I/O stream going from a terminal to something else, really?

    The IOC/USOC/media companies are so worried about "protecting" their investments that they are pissing on any sort of grassroots or whatever about it.

    I am enjoying watching some of the coverage, but because the US coverage is SOOO overly American-focused, it's disappointing.
