Reply-To: [EMAIL PROTECTED]
Top and ps seem to disagree wildly about how much CPU time processes use. If
I have a process that's chewing lots of CPU, top will report it near 100%,
yet ps shows only moderate CPU usage (typically < 30%). I wrote a little
Python script to read the relevant /proc/PID/stat file and compute a
percentage from that and got results that tend to agree much better with ps
than with top. Treating /proc/PID/stat as an array named stat and the
previous stat reading as an array named last, I calculated the CPU
utilization during the latest interval as
((stat[13]+stat[14])-(last[13]+last[14]))/interval
where all numbers are in 1/100's of a second. My interval is currently set at
five seconds. Does ps perhaps compute CPU utilization over a much longer (or
shorter) interval? If so, why does my calculation differ so much from top's?
Presumably both use the same raw data and the same interval.

I am trying to set up the Apache server with RedHat5.2 with my dynamic dns
address.
1. When I go to my loopback address (127.0.0.1) I get the Apache index page
telling me
that I have correctly installed Apache.
2. I use traceroute www.redhat.com or any other address and use the #1

that this is my dynamic address.
3. I open Netscape Navigator and go to this address and get a Netscape:
Error
Netscape's network connection was refused by the server 209.32.53.62 .
The server may not be accepting connections or may be busy.
Try connecting again later.
I have looked at the configuration files but have not found anything. what
am I doing wrong?

>From what I've seen (screenshots), I also prefer the look of GNOME.
But does anyone have experience, in terms of everyday use (not as a
programmer, but as someone who uses their system for daily tasks with tools
like StarOffice)?
I'm interested in as many personal stories about individuals' experiences
with both KDE and GNOME so I (and others who read this newsgroup) can get a
good idea of the stability, usefullness, etc. of both KDE and GNOME, and
thus compare them in order to make an informed decision before fumbling
through one or the other and crashing my (and their) system.
I am really looking to get a full fledge Linux system soon (I use Linux only
for web servers now) to migrate my desktop operations, but am looking at Red
Hat 5.3 (coming soon, so I hear) with GNOME support (and drag-n-drop) or
Caldera with KDE.
I've been impressed with the GNOME hype, but pretty much warned away by all
the negative reviews (system unstable, crashes every hour, etc.). I
understand Red Hat is working hard on bug fixes and GNOME stability... but
any help is very much apreciated in terms of comments from first-hand
experience with both KDE and GNOME.
The other issue of concern is the license situation with KDE... I thought it
was open source, but Red Hat tells me that the reason the don't support it
is because of the license issue...
Thank you, Linux community! :o)

Date: Thu, 18 Mar 1999 15:22:48 GMT
<snip> Problem with ZyXel Omni.net TA.
I own one, I don't use it anymore because of an upgrade to DSL.. While I'm
here, if someone wants it contact me via Email for it, my return address is
valid.
Now, to the problem at hand. Getting PPP working.
I found that the INF files for Windows set up the TA very strangly. I avoided
the problem entirely and used an old DOS term program to set it up. If that
sounds too hard, use the Windows 3.1 config program it comes with. That made
the job a bit eaiser. To set it up yourself just go through the back of the
book and set the options with the AT commands. It's just like a high-speed
modem. Now dial "ATD<number>". Did it work? If not, what errors did you get?
I don't have the LCD model, I just use the huge array of LEDs. :)
When doing this testing, do NOT use the dialer programs Win95 comes with. Use
a BASIC terminal. In Linux 'minicom' should work. In fact, don't load Win95
at all.
Second thought... if it works under Win95, dial out with it (so the unit gets
configured) then go into a terminal and do AT&W0. Now in Linux use ATZ as your
init string. That might work. When loading the terminal make CERTAIN that it
does NOT init the 'modem'. That will change all your settings and mess it up
again.
Hmmm... this may work. Go into the advanced dialing properties (I think..
look arround) and set the modem dial command from ATD to AT&W0D. It will
still dial, but it will save the settings right before dialing. Then just ATZ
to get them back.
Just like a normal modem, there are many ways about this. I'd try that last
one first, it is the easy way, if it works. If the unit is working in Win9x
then it will work under Linux, you just need to get the settings right. When
configuring the PPP daemon just config it like a normal modem with ATZ as the
init string. The dial command should be ATD<number>. If you have dual channel
available use ATD<number>+<number> to get the second channel connected. You
can use the same number both times. There is also an S register that
eliminates the need for that dialing sequence if you have a problem with the
software.
In looking at this message, I noticed that my zeros look like 'O'. The AT&W0
command uses a ZERO, not the letter 'O'. ;) Just in case your font is set like
mine.
Good luck, let me know if you get lost allong the way. :)

I think I misunderstood this experiment you tried (although I have
no idea why I did). It makes no sense to run xterm or rxvt without
an X server running.
Your error message looks like it comes from the "hostname" program,
and I do not know why the terminal emulator would call it directly.
(Besides, I ran "strings - /usr/X11R6/bin/xterm | grep hostname"
and came up empty.)
What happens if you invoke "hostname" from the command line?
What happens if you invoke your shell in a virtual console?
Try putting a (temporary) debugging message at the beginning of your
shell's rc file (.bashrc, .cshrc, whatever is appropriate -- you may
have to _create_ it), of the form
echo "starting $SHELL rc file";
this will help determine whether the error is occuring during the
shell's startup procedure.

I am currently benchmarking our PC with a PGI f77 compiler
and some small (real world) molecular dynamics code.
Our PC (AMD K6) is slower by a factor of 5 compared to the SGI.
I never expected the PC to outperform the SGI, but thought that
it should show similar performance for small programs
(simply based on the SPEC numbers).

Of course the PC is still the most cost-effective
(2k DeutschMarks vs. 40k DM for the SGI).

Subject: Re: PostgreSQL question
Date: Wed, 17 Mar 1999 21:49:50 GMT
There are a variety of ways. For general use, Postgresql comes with
both ODBC and JDBC drivers. Any conventional thing you can put in a web
page (CGI scripts, for example) that can use ODBC or JDBC can therefore
get to Postgresql data.
The most powerful way to use Postgresql with web pages is, IMHO, to use
Java and JDBC. You can write applets and servlets which can use the
JDBC and do very powerful things. This requires non-trivial Java
programming ability although isn't particularly difficult.
In the near future, Java Server Pages and an XML->Java will be widely
supported by web servers and will allow you to directly insert calls to
JDBC in web pages themselves, with at least as much expressive power as
MS Active Server Pages but with full portability.

That being the case, you could configure Ghostscript to run on the
Windows box and print to the Windows printer driver. That would get
you the least imperfect color; if we assume that the HP Windows driver
produce the most accurate color possible...

The 882 appears to be a PCL 3 printer, like most of the other
DeskJets. It should work well with both the hpdj driver or the cdj850
driver.

You should skip it altogether. Its contents are generated by the
kernel at runtime; there's no "real" device behind /proc. Trying to
save/restore, say, /proc/kcore, which is a copy of the kernel's
addressable memory, can cause huge problems. Most of the files there

Yep, because your DNS isn't right. (The system you're telnetting to is

Subject: Re: g77 anyone?
This doesn't surprise me really. All of the RISC chips (Sparc, Alpha,
MIPS, etc.) have better floating point
performance than Intel chips due to RISC vs. CISC issues and cache size
(unless you get a Xeon). What compiler
you have also makes a big difference and in general the vendors have very
good f77 compilers (years of optimizing
experience). If you want to do serious computing on your system, I suggest
checking out commercial fortran
compilers (see the fortran FAQ or Fortran Market web site).
In particular, I recommend Portland Group's compiler. I was able to get
the same performance with a 450MHz
Pentium II as with a 300MHz Sun Ultra workstation (not with Sun's latest
compiler however) (the problem size
was fairly small also). All things considered, I am impressed with the
performance of a machine that cost less than
$2k and a compiler that runs about $500.
