I didn't say that you should go look for a functional language,
just that it would be unwise to disqualify SML on the grounds that
it is a "functional language" (which is contestable, since SML
programs can and often use side-effect in the form of assignment
and I/O.)

Yes, and they all have different characteristics. I don't think
you would lump them together and select one at random - you would
probably evaluate each language (w/ implementation) on its own
merits. I'm just saying that you might consider doing the same
with SML. It is a well-designed language with a set of high-level
features (e.g. automatic storage management, runtime-safety, static
typing without type declarations, parametric polymorphism,
exceptions, a powerful module system, pattern matching of
arguments, and more) which is more complete than in most other
procedural languages. These are, in my opinion, good features even
if your program is a non-functional one.
Regarding support, it's true that it is not a mainstream language,
but there is at least one commercial implementation and several
free ones. If you restrict yourself to mainstream languages, I'd
say that you find no language which is even close to matching the
high-level features of SML.

You talk about "functional languages" as if they were all the same.
But they aren't.

I disagree. Even if you don't buy into the OO gospel, you can
benefit from the improved abstraction features of C++ in a
procedural program, using objects as abstract datatypes. I don't
think it would be confusing to C++ programmers at all - on the
contrary, I think it would be easier for outsiders to understand
than the design of the typical C++ program which is often
complicated and intertwined.

Date: Thu, 18 Mar 1999 08:56:40 +0100
Hi!
I had this problem a week ago, I experienced _exactly_ the same things as
you are. I just couldn't figure it out. This was driving me nuts. The
solution (or should I say the blessing?) was Partition Magic 4.0. I know, it
is a Windoze application, but it is a great program still.
Lemme tell ya! There I was, chasing those extra 2GBs that I KNEW I had, but
niether DOS/Win98 fdisk nor linux fdisk/diskdruid saw those 2GBs. Installed
Partition Magic and there they were. Two clicks and my disk was partitioned
_exactly_ the way I wanted it to.
So, my recommendation would be for you (or your friend) to take a look at
that program.
And my wish is that someone writes an open-source Linux Partition Magic. I'd
love to do it myself, but these things are way over my head.
Oh, btw, two more things:
1) I got confused by the fact that you can have 1MB = 1024 kB OR 1MB = 1000
kB. This made me think that not even Partition Magic saw the entire disk.
2) What game was it that you son installed that required 1.4GB to run? Just
curious.

You can start the system in single user mode by typing - at the lilo
prompt
linux single
This will give you a shell as root without needing a password. You
should now be able to manipulate /etc/passwd to allow a root login. Note
that in single user mode a lot of the system is not yet started (see
contents of /etc/rc.d/rc3.d for items which start in the default run
level 3).
This is of course useful to know if you forget the root password ;-)
When you are done type 'exit' and the system will continue to start up
as normal.

oh yeah... I have experienced similar problems... :-))
in my case the cause was that the provider authentication procedure
treated CR/LF like two times Enter and hence already assumed an empty
password... crazy...
there is a modem setting page somewhere in the kppp setup procedure
where you can tell kpp how to conclude modem commands; i set mine to
CR (or was it LF, anyhow different from CR/LF) and the result was no
more problems with the ppp authentication...
Hope this helps,

This is all down to the way in which NT has been implemented in your
environment. You can rant away, but any operating system is only as good as
those who implement it (and I am by no means defending NT here). You could
apply your gripes to UNIX or any other OS...... maybe your real issue is
that the people responsible for implementing NT do not have the correct
level of understanding?

I found the solution:
apcupsd 3.5.2 does not work correctly. The same configuration file does work
with apcupsd 3.4.9. I tested both with Suse 6.0 and Redhat 5.1.

You may be able to do it like this:
LINES=43;export LINES
if you're using BASH as the shell and if the window really is 43 lines.
I've not tried it on Linux with the tools you mention, but I do similar
things on onther unixes with good results.

This is a matter of opinion - according to Larry Ellison there's no need for an
OS on some servers. If you've got a server acting as a router then a GUI does
seem superfluous, but then I wouldn't use NT as a router. On the other hand, a
domain controller benefits from a GUI (as far as I'm concercerned). Basically
if you don't like a GUI, don't get NT. One size doesn't fit all.

If you're running 3.2v5, do 'undelete -l' in the directory you deleted the
files from. If it prints the name of the files (followed by version numbers),
you're in luck. However, it probably won't; in order for versions to be saved,
file versioning has to be turned on on the filesystem and has to be enabled on
any directories you want it to work in. It's one of the "stealth" features of
the HTFS filesystem - little known, little used.
