Hell, Pat, in 200 years, I'm sure folks will still be bitching about
Windows XP 2204 being too bloated and crash-prone to run ANY of the
latest 4D-games in 37.1-channel psionic surround-think. I mean, come
ON! Win2200 rulz! W00T!


And MS_Word 2204 will require a semitrailer full of terabyte
SVHDDVDs. run like a Sloth on your MeraHertz Anthill processor, and
provide no more useful functionality than Word 6.
ANd the Stupid Paper Clip will still be standing over your shoulder in
3-D. (I don't wnat to think about the Idiot Butterflies)


Luckily by then the BSOD, countdown timer and auto reboot
will happen in mere microseconds, so fast that the average
user won't even realize that their system is crashing,
locking up, and rebooting hundreds of times a day.

But VMS, like Unix has both command line as well as GUI. X-Windows appeared on
VMS at about the same time it did on Unix, and in fact, VMS had VWS (more
primitive GUI) prior to that. (this was before Windows was actually usable,
but well after MacOS).

Microsoft started with a toy operating system for single users without any
security then added windowing as an application. Even though Microsoft finally
wrote an OS and new look, the need to keep upwards compatibility to preserve
market monopoly required the current windows to inherit many of the problems
of the DOS/Windows days. And the current windows is still not really designed
for multi-users. (although it now has multi tasking).

VMS started as a multi user system with security, and windowing was added as
an application and there was no need to rewrite the OS because it was rock
solid.

Unix started off as a geek operating system without much of a need for
security, and security was progressively added, but at the core, it is a
multi-user system.

But what users actually need (despite contrary propaganda from microsoft),
is a *stable* and *predictable* and *secure* system.

That's not sufficient.


Agreed. However:

There are any number of stable, predictable and secure systems that
are unusable by all but a handful of specially trained experts
(VMS, Linux, VxWare, Multics, OS/390...).


I wouldn't think they're only useable by specially trained experts.
They didn't see their market as a consumer OS (the owners of VMS didn't
think it had any market at all, judging by appaerances), and thus
didn't make them as easy to use as could have been done. Remember, WNT
conceptually is VMS V1 underneath.

No, it's the applications that made Windows the success it is. Standard
evolution in action: a small advantage in fitness will, in finite time,
lead to extinction of all competitors. Only changes to the fitness land-
scape can change that.

VMS is as good as you could possibly get from a command-line system,
and you hardly need to be a "specially-trained expert" to run it. Far,
far easier than UNIX or DOS. Let's say that "Search" is a lot easier to
explain than "grep" and all the versions of VMS more-or less work the
same. And $ Help is a lot better than man .

We plunk people with no command-line experience at all down at a
VMS terminal with a cheat sheet and they are doing something useful in
an hour. Plus you can get a GUI wrapper for VMS that's at least as
straightforward as Windows - and about 10 orders of magnitude more
reliable. It's also far more reliable than Sun UNIX.

I use 4 different OSes almost daily - VAX is the most reliable by
far, Mac OS 8.6 is by far the easiest and most useful, Sun UNIX is at
least tolerable, and Windows is like a f*cking torture session that
seems to have trouble reliably retrieving email from it's own dedicated
server designed to work with it. And requires almost constant
maintainence by me (and the other users) and an entire IT department.

XP *is* a vast improvement. Nonetheless, a screwy WDM sound or video
driver can still BSOD the system.


I've only heard rumours of OSes that could withstand a substantial driver
bug, never seen one - and I've seen a lot.


I think there was an anouncement recently of some 'middle layer' system

OS - middle layer - drivers

set up in such a way that the most a driver could crash was itself and would
then be auto-restarted (if appropriate).

If you allocate some memory and the code that deallocates it doesn't
always get executed, it means that your logic is flawed and you
haven't done the due diligence to ensure your code reflects the
intentions all the time.


Or it may mean a deliberate decision that 0.000001 seconds of CPU time
is less valuable than hours spent by a programmer, followed up by
hours and hours spent by program reviewers.

Which is cheaper: a microsecond of computer time, or 24+ hours of
people time?

(Oddly enough, this is on-topic for sci.space. Misplaced priorities
aren't limited to software engineering. Spacecraft engineers sometimes
focus on launch mass or GLOW to the exclusion of other important
parameters.)


Get a clue!
Sloppy memory management relates not only to processing time, but also to
system stability! You are thinking like microsoft.

As to your remark :
Which is cheaper: a microsecond of computer time, or 24+ hours of
people time?

The microsecond, when it is in a piece of code that is executed thousands
of times per hour, on millions of computers running that code.

Accurate coding only requires more time than sloppy coding when the
programmer's skill is not sufficient to the task. For a fully competent
coder, accurate code is *easier* to create and debug than sloppy code!
Pity your remarks place you in the "sloppy" category.

On or about Tue, 30 Mar 2004 01:03:24 GMT, Greg D. Moore (Strider)
made the sensational claim that:
How quickly people forget the Sendmail worm which was quite disruptive in
its day.


I think that safely qualifies as prehistory here on teh interweb. Anyone who
thinks unix should be held up as a shining example of operating systems should
be forced (preferably at gunpoint) to read the Unix Hater's Handbook.
