Subject: Converting mbox to mbx format
Date: Sat, 21 Aug 1999 10:53:17 -0700
How would I go about converting my inbox which is in mbox format to mbx
format? If anybody can give me complete step by step directions, I would be
very thankful. I want to do this, but want to make sure I am not going to
screw anything up. I am currently using Sendmail 8.9.3 and procmail as the
local delivery agent. I am also using a .procmailrc file in my home
directory that I filter incoming mail with. I want to continue to filter
the incoming mail into folders. I have downloaded the imap-utils from UofW.
I am currently using the UofW IMAP server.
Thanks,
Jeff
p.s. I want to do it for the whole server? I am running Linux. Also, I
want to make it the default so if I create any new mailboxes, they are now
in mbx format.

After installing StarOffice, my Gnome menus all disappeared (when
StarOffice inserted its own entries into Personal folder).
How can I go about reinserting the Gnome menus?

It means that your network card is in a mode where it can listen to
traffic to/from all network cards on your subnet. Normally the card
only listens to traffic directed to itself, but in certain circumstances
it's benificial to listen to all traffic. Those circumstances include
legitimate uses such as debugging network drivers and not so legitimate
activities such as viewing other users private information.

You need to have at least the basic parts of KDE installed. Try
http://www.kde.org. Either that or you have the wrong .rpm for your
system.

Do you have DNS setup correctly? Try, "ping news" if that doesn't work
try "ping news.<yourISP>.com" if that works use it instead. If that
doesn't work then you haven't setup you networking correctly.

Is Mandrake based on RH 5.2 or 6? If 6, then you do have the wrong
.rpm. for the kde program.

Yes, but it is still a mistake to characterize it as a limitation
of the hardware when in fact it is a design decision that is
the problem.

Turn down the gain on your microphone input. If that doesn't work, try your CD
input and your line input.
If you don't have adjustable gain on your card, just turn the microphone (or
whatever input it turns out to be) down or off in the mixer.

Did you set the partition ID's to 0xfd, this is needed for autodetection of
raid partitions. see the documentation about software-raid.

Subject: need routing help

I have a lack of understanding with this. When I do ifconfig eth1
192.168.0.1 netmask 255.255.255.0 up it works fine, but does not reflect
the 192.168.0.1 in the route table. What I get is a 192.168.0.0 netmask
255.255.255.0 and I would like to know what do I type so the routeing

The main kernel won't run on a pre-386 x86 processor. There is an ELKS
project for linux on earlier machines, but it won't work out of the box
and do everything you want.
What your friend needs is a copy of Minix, the unix clone which inspired
Linux from Linus. Try http://www.cs.vu.nl/~ast/minix.html or a web

It does sound as if there may be a problem with the disk. fsck
should find any problems with the filesystem.
With the SunOS, one could boot from a CD and use the Sun format
program to do various disk checks, e.g. read, read/write in place,
which were theoretically nondestructive and several destructive
disk checks.
There may be similar programs for Linux, but if so I don't know
what they are. mkfs with the -c option will check the partition
for bad sectors before making a filesystem, but that is highly
destructive.
You might have to use some Windows program.
Let us know what you find out.

Try and launch the Win 98 setup like this: setup /? , this will display
a list of possible switches to add to the command line. I'm in Linux
right now so I can't check it but the ones you want all start with /i,
/im /is etc. this should bypass the scandisk and disk space check and
proceed right into the install. You may want to boot to the DOS 7.1
(command prompt only) and run scandisk manually before you do this just
to make sure the pattition is all clear.
Hope this helps.

Personally, I think the idea of Linux certification is distastefull and
a really bad idea if it catches on. Unix has never worked that way, its a
learn by doing and doing well method. The current certification process
is IMHO a racket designed to make big bucks for the certifiers (MS is
real big in this) and make it easy for incompetent human resource
placement people. Its becomming more and more common for quick, no
experience neccessary, trainees to gain a slip of paper whose sole
purpose is to improve their marketability at the expense of their
qualifications.
Sorry, I know this really does nothing to answer your answer and I don't
mean this to be an attrack on you or your skills, which may be quite good
as far as I know. I'm just sick of the whole certification business and
had to get that off my chest.

Yes. Until the compiler is improved, etc.
Either way, except in very specific circumstances where the code _must_
be as fast as possible (drivers, very busy daemons, etc.) and I know
that this is what's slowing it down (see below) it's simply not worth
my effort to worry about it.

Exactly my point. In widely ported and portable code, these kinds of
things are unknowable and, in general, not very interesting as
efficiency increases anyway.
It's a rare, and probably pretty specialized, program that will see any
significant benefit by having its loops count down rather than up.

No thanks. I have much better things to do than compare the output of
Sun's compiler vs AIX's compiler vs. HP's compiler vs. Greenhill's
compiler vs. GCC on each of those platforms, etc. etc. worrying about
these kinds of optimization issues. I'm sure the results will just as
often as not be contradictory anyway.
As I mentioned above, it's a rare program where micro-optimizations like
this will even be noticeable. The vast majority of slow code is due to
algorithm design issues or other kinds of latency.
You should read the famous whitepaper "News Need Not Be Slow", by Geoff
Collyer and Henry Spencer. There're a lot of good nuggets for practical
and results-oriented optimization in there.
ftp://ftp.cs.toronto.edu/doc/programming/c-news.ps
I'm not saying that adopting habits that are more likely to lead to
efficient code is bad (I decrement where possible, and I also use lots
of temporary pointer variables instead of int indices, for example). I'm
just saying it's very likely not worth going back and re-editing code on
a whim.
