- In fact, I found Ehud's message to be a flame worth keeping around.
-
- At MIT we used to call something with the right tone and technical
- content a "FLAME."
-
- If there was not sufficient technical content then the thing
- would not even be -elevated- to deserve the term "flame" and
- instead would be considered mere whining, or worse.
-
- ----------
-
- Flame:
-
- The real problem today is that there is no technical respect for
- operating systems, period. Of what benefit would it have been
- to DIGITAL to make VMS truly call-oriented across all functionalities
- at the DCL level (that is, there would no longer be -any- "executable"
- files that are activated by the RUN command, instead every functionality
- invoked by the command interpreter would come from essentially a kind
- of LINK/SHARE'd object, and there would be a more general kind
- of LIB$FIND_IMAGE_SYMBOL with the ability to deactivate images no
- longer needed). In short, give us something of Multics circa 1975, only
- better?
-
- Would that have helped in DIGITAL in the marketplace?
- Is Microsoft "NT" going provide something like that?
-
- All the emphasis is on the features of the SUBSYSTEM or worse, the
- graphical user interface.
-
- And heck, if you are good enough, and can make kernel mods if needed,
- you can get just about any kind of application subsystem running
- in anything, even UNIX.
-
- A possible exception to this flame might be the IBM AS-400 system.
- Now perhaps IBM was willing to invest in making the base operating
- system provide better functionality in areas such as dynamic linking and object
- management because the extra complexity of such a thing makes
- it a lot more difficult to reverse engineering and connect into,
- in addition to enforcing a certain quality and consistency
- in all applications that are done in the environment provided.
-
- Obviously another big exception to this is all the volume shadowing
- and vaxcluster and other stuff associated with VMS. That kind of thing
- goes a long way to making the operating system responsible for providing
- a consistent and robust environment in which an application can run.
- But still, it isn't as iron-clad automatic and unavoidable as what
- was available in old Multics or AS-400 land.
-
- But then again, all this could be provided in the SUBSYSTEM itself.
- e.g. private journalling and backup activities in a database implementation.
