Hi,
if possible, move the card as far away from the CPU and other cards
as you can. Try to keep any cables that run to the card away from other
components. Turn down the microphone level. Some people have gone
as far as producing a shielding shroud around the card, put you have
to be careful about shorting out or overheating the sound card.

My screen blanks every 10 minutes of no activity.
This is only a screen blanking...not a BIOS issue...BIOS has
power saving completely disabled.
1. How do I increase the time until it blanks the screen?
2. How do I turn off "screen blanking" completely?

Note that you can't specify the timings unless you're using a device
that supports it (such as Matrox).

Ronald,
Thank you for your answer.
I am studying the material (some manuals and HOWTO). I have not yet
installed Linux, since I do not dare to install it alone. I have a friend
who will help me with the installation.

Downloaded Slackware some years ago and never bought a Linux cdrom.
You need the install disks, the A series of directories (one directory
per floppy) and almost certainly the n series (communications). Try
ftp.cdrom.com in the download section or ftp.metalab.unc in
/pub/Linux/distributions/slackware/slakware.

Subject: xman retrieves garbled documents -- bzip issue?
Date: Sat, 21 Aug 1999 15:53:42 GMT
Hi,
After installing Mandrake 6.0, xman no longer works. The sections
appear in the directory listing, but opening them results in a window
that contains a garbled mess of characters. In addition, I receive
error messages from geqn stating an invalid character was found. I
imagine this is all occurring because the man pages are no longer
standard script file format, but instead in bz2 compressed format.
When I run the regular man command, I can see the pages fine -- so I
figure that man can decompress files as needed. Is the same true for
xman? I don't see anything in the xman manual page that pertains to
this.
Any help would be appreciated.
Regards
Steve

That is really bewildering and a bit scary. Win98 and
Linux can certainly live on the same disk. I've installed
Linux on several machines with Win98 on them.
One solution might be to tell the Win98 upgrade program
not to repartition and then continue with the installation.
I hope that is possible.
My guess is that the Win 98 upgrade program checks the MBR
and doesn't like what it sees. But it shouldn't care about
anything except the Windows partitions.

I'm very interested in studying for Linux certificate exam. I know there is
a certificate for Redhat, and also a separate certificate shown at the
website www.linuxcertificate.com
Is there good textbooks specialized on studying for linux certificate exams?
If there's anybody who's certified, how difficult was it (like comparing
with MSCE)?
Just like there are tons of books on MSCE exams, I've been searching for one
for linux exam, but can't find any. I passed MCSE+I exams basically by
studying those types of books (with hands on works, of course). I'm sure
linux certificate will be very big in the near future. I would think that
there are such books available....

In article <[EMAIL PROTECTED]>,
[EMAIL PROTECTED] says...
> The problem is that you can spend your time hand-optimizing an area of

I think we are mixing up different issues here.
1) Optimization of existing code. Well, sure, run a profiler and see
where the time is being taken. Then go optimize the parts where the time
is being taken.
However, even when you find out where you are spending your time that
doesn't mean that that is the routine that should be fixed. It could be
that a larger design is what is flawed.
2) Writing code to be fast in the first place.
There are various aspects to this
A) Coding styles down at the level of loops and groups of statements
that will result in faster code. The classic example is to decrement your
loops rather than increment them. But there are lots of others.
B) Coding styles that reduce heap thrash, improve locality of
execution, and so on.
I would argue that good coding styles, once one has internalized them,
are not much if any additional effort to practice. So why not do them
everywhere?
C) Algorithm design and larger program design issues.
Note that in some cases if you do not do your initial coding to be
efficient in the first then you may end up with an amount of code that is
so large by the time that you find performance problems that you either
are not going to be able to fix these problems or you are going to have
to slip your schedule in order to go back and do rework.
The real attitude that I'm arguing against here is the idea that
optimization can be left to some final phase of the development process
and that profiling at that stage will be adequate to make the code fast
enough. I do not believe it. I think that performance has to be designed
in from day one. It is not something you can tack on afterward with a
profiler. You think Microsoft can profile its way thru Win32's code base
to make its slower parts as fast as Linux's faster parts? I don't think
so. Not without massive rewrites.
This philosophy is analogous to the philosophy that the US carmakers
and other manufacturers had for many years that (once upon a time when I
worked for one of those big car makers) we called "Throw it over the wall
design". Basically, in that case the design engineers didn't worry about
the problems they were creating in their design for the production
engineers. Well, in the same way one can't go designing software just to
be functionally correct and then go in and only work on performance at
the end using a profiler as a guide.
Too many times I've seen code with performance problems that was badly
flawed in design that required a lot of rework in order to make it
faster. It wasn't a matter of identifying the 1% part of the code that
took 90% of the time.
In one case the 90% of the time was spent in copy constructors. Well,
what is one to do in such a case? Write an optimized version of memcpy?
Its not possible. The real problem was that idiots had written their code
to copy the same data many times into many objects as it was being passed
around between different translation and protocol and call layers.

Again, sure, a classical example. I only wish even half the optimization
problems I've encountered fit this profile (pun intended <g>).
However, to take a real example, I know of a windowing library for a
type of touch screen embedded device (I worked on a different part of the
larger project that it was a part of) whose performance problems are
extremely diffuse. There is no hotspot place to optimize. This is
considered to be a serious problem to a couple of companies that are
involved with this project.
One can find oneself with hundreds of thousands of lines of code with
no single 1% place that is taking all the CPU thru-put. Or if it is
taking that thru-put there may be no way to optimize it (eg my memory
copying example).

If you don't mind doing your profiling running on Intel hardware (I've
personally found that most performance problems are not related to
processor type though as I've pointed out there are counter examples with
some of the RISC architectures in particular) then check out Intel's
VTune tools.
http://developer.intel.com/vtune/vtcd/index.htm
I have a friend who deploys on a couple of CPU architectures who thinks
VTune is the best he's found to date. I don't know if it will address
your specific question or not but apparently it has some pretty nice
features.

Sendmail is a mysterious program, sent to baffle us. If you're serious

O'Reilly & Associates; the bat book. Very dense reading and you may

Simply because `pop3` isn't a number. Try either 23 (SMTP) or 110 (POP3).

I agree, we have to wait until they ship to see anything.
nmap showed only port 80 open. That is fine and wonderful for a box
that ONLY is running a webserver, that does not log anywhere else, that
does not have printing capability, that does not have any type of
services running - sendmail, nfs, logger, time synchronizer, netbios,
snmp, imap, domain, pop-3, smtp, nntp, etc. Who runs such a box? Not
even a desktop word processing machine is that barren.
Now, put a desktop box with all the 'typical' services turned on and not
this laboratory, sterile thing with nothing but the web server
running...
That's why their challenge is more than a dumb stunt, it'll actually get
people broken into because they'll have heard of it and will not think
they need a firewall or a packet filter and they'll have all the normal
services turned on.

My experience was that of the original poster--just uncomment the pop3
server in /etc/inetd.conf, HUP inetd, and it was ready to go.
