-
- I'm getting really tired of this baseless accusation. Come to a meeting; ask
- the people there, who are employed by vendors, if they implement the stuff
- they're standardizing. The numbers will surprise *you*; they'll surprise
- almost no one else.
-
- >Why is POSIX ``standardizing'' printer interfaces?
-
- Well, because you can't sell a system today that supports neither SysV lp or
- BSD lpr; that seems to indicate the market has settled on a couple of nearly
- universally reviled standards. You might ask the Palladium gang from
- MIT-Athena about the degree of interest in their stuff. You might check
- around at the number of implementations of it. Lots and lots of
- implementation experience, just what you want to see.
-
- >Or protocol-independent networking?
-
- Because you can't sell a system today that supports neither (SysV TLI or
- X/Open XTI) or BSD sockets. Because the clamor to standardize *both* of
- them, or just *one* of them, is deafening. Lots and lots of implementation
- experience, just what you want to see.
-
-
- > Where are the customer demands for these standards?
-
- Tell me - would you buy a system that didn't support Berkeley lpr and
- sockets? If you're a SVR4 kinda guy, would you buy a system that failed to
- support lp and TLI/XTI? *That* is customer demand.

-
- The early revisions of XTI, the early history of TLI, the Tahoe and Reno
- versions of OSI sockets; and those are just the very well known ones.
-
- >If not, then you're inventing and ``standardizing'' poor solutions.
-
- Dan, sad to say, if one talks to a large number of users, one often hears
- the phrase "better a bad standard, or two weak conflicting standards, than
- no standard at all." I may disagree with that sentiment, but I have heard it
- expressed many times. As for the solutions being poor, I happen to disagree
- with you there; many of them are *different* from what you might think are
- good solutions, but few of them are demonstrably poorer, and many of them
- are demonstrably better against the set of criteria POSIX has to deal with.
-
- Finally, I think the fact that POSIX standards are continually being issued,
- being revised, and that there is every expectation that this will continue
- into the future for quite a ways, is some proof against the ossification of
- the state of the art through standardization.
-
- When's the last time you've been to a POSIX meeting, Dan? Perhaps you might
- want to come down and watch the sausage being made; the rules they play by
- address many of your concerns.
