- GNU may however be a bit too Open... Problem with GNU is that you never know how

- nice, occasionaly you find some add on that is a real dingbat.

- My situation too... Only I have problems with two different versions of UNIX
- from the same vendor!!! Also the hassle of porting stuff from one site to
- another (same platform, same software, different setup)... without super user
- privs I refuse to do this sort of work - let the buggers stew.
-
-
- From my point of view Open system means a system open to the User as well as the
- programmer. It is important to be able to connect anything up, to be able to
- talk to any machine, to be able to reconfigure the machine at the user level.
- However unless the user is able to interact with the machine in a comfortable
- way then the O/S just isn't doing it's job.
-
- To me UNIX is closed because it hides the most powerful methods of doing things
- from the user. Much of this is deliberate mystification (biff, grep, man). The
- other thing that is closed about UNIX is the minds of too many of it's users. It
- is the FORTRAN of the 90s. They know one way of doing something and they are
- sticking to it. They are also going to try to force you to use their way if they
- can.
-
- I recently suggested that AT&T should have provided a better UNIX shell years
- ago. One reply I got back was "If there was a demand for bozo-shell then it
- would exist". Someone who wants the directory command to be called "directory"
- instead of "ls" is a bozo then? Well I am quite capable of typing ls, in fact I
- alias ls to dir. However the people who I have to help with the system don't
- know that. When I tell them that something is simple I have to punctuate an
- explanation of a procedure with the decyphering of the cabalistic runes
- required.
-
-
- The big problem with UNIX is that it's going to be impossible to connect it
- properly to an intelligent file system. UNIX has this opinion that all files are
- sequential. An intelligent file system might have quite different ideas. If I
- can't interface my computer to a disk drive because the operating system is too
- stupid to handle it then it is not an open system.
-
-
- Problem with O/S flame wars is that everybody seems to see them as VMS vs UNIX
- vs W/NT vs whatever. Real question is what is the operating system going to look
- like that is going to replace UNIX and VMS (and Windows/NT) ?
-
- POSIX means that we can develop new operating systems and have a vast software
- base avaliable from day one. We should be looking for new ideas for O/S design
- that take advantage of this opportunity.
