Are you talking 1000 cycles, 1,000,000 cycles, or what?
I saw a catalog ad in which SanDisk offers a "one million picture
guarantee" on their CompactFlash chips.
Look into the "-o noatime" option for /bin/mount, and check the
cycle time and other options for bdflush ("man update").
Except for these, the defaults for filesystems managed by the
Linux kernel come very close to "minimum writes".

let me ask this: why should changing the uart type to 8250
allow transfers to complete that the 16550a will not?
this is the most puzzling part.
The 16550a has a 16-byte buffer where the 8250 has only one byte.
also 16650 and 16750 uarts work fine with my modem except in the case
of certain ftp gets. do you think that active/passive mode should have
anything to do with this? (by the way, if I am wrong on the uart specs
let me know)

Hi,

Thanks for the reply. The paging makes sense. I believe the 128 MB is
gone in the 2.2 kernels. It may be a memory problem that I've been

Subject: Upgrading an enternal USR Courier V.Everything *without* MS-Windows...
Date: Thu, 17 Aug 2000 19:58:59 GMT
I have a 33.6/28.8 USR Courier V.Everything and I would like to upgrade
it to a V90 (56K) modem. The problem: I *don't* have MS-Windows
installed on my computer. Since a full version of MS-Windows costs
$189, with the added cost of the modem upgrade of $60 == ~$250, this
makes about $250. Which happens to be close to the cost of a *new*
modem... I can either buy a copy of MS-Windows, install it on my 345meg
C: drive (presently containing MS-DOS 6.2 and is mostly full of old .tgz
files) or buy a new modem. Yuck.
Does there exist a version of the upgrade program for Linux? Does
anyone what the upgrade *actually* program does? This is an
*external* RS232 serial modem. What can a *MS-Windows* program do with
the serial port than Linux cannot?

and I get:

I don't think .login is a good idea.
Mutt for example has the ability to start subshells. So they could execute
whatever they want. You could try to give chroot a chance,
but even then, it's a hard work until it'll work.

The easy thing to try is to disconnect any phones you might have on the
same line. See if that makes a difference. Also if you have a jack at the
entry point for your phone service see if you can plug the modem in there.

The only negative I've heard is they have some sort of download limit.
Plus the usual no server rules that the cable companies all seem to have.

I don't see that behavior on my RedHat system; I just
changed it to do "date >> /tmp/this" (just so I could see
that it responded) and it keeps on adding to the file every
time I fat finger it.
It maybe that your distro treats ctrl-alt-delete the same as
"once"; you might try issuing an "init q" and see if that
changes its mind..

Nothing, if you knew what to do.
Why not just prevail upon someone you know who DOES run
windows to do the flash for you? Once it's done, it's done,
and you can put the modem right back where it and you will
be most happy..

Subject: Tracking page replacement in Linux?
Date: Thu, 17 Aug 2000 20:45:05 GMT
Hello Everyone,
I'm a graduate student at the College of William and Mary, and I have a
question regarding how to track page replacement that has arisen in the
course of my research. I'm working on doing load balancing with a
coarse-grained parallel program that calculates eigenvalues/eigenvectors
of large, sparse matrices. This is an application that can require
hours of running time to yield useful results, and, furthermore,
requires lots of memory. Hence, if another process is running on a
compute node and competing with our application, then things can slow
down dramatically because the system has to start page swapping to
disk. Since most processes that would compete with ours probably would
have lifetimes significantly shorter than the many hours that our
application run, it might be possible to speed up things by having our
application back off some (that is, start doing less work than usual)
when it senses that lots of swapping is going on.
The question that arises here is: How can my application tell when lots
of page replacement is going on? Note that I am actually interested in
page replacement proper, that is, what occurs after a page fault when
there are no free frames of physical memory. I know that in /proc/stat
there are fields that tell the number of pages that have been brought in
and out. Monitoring those could be a possible way of telling if page
replacement is going on, but that would be rather inexact--Linux, after
all, does plenty of demand paging all the time. It seems that the best
I could do would be to say that once the rate of paging passes some
threshold, I'm probably doing page replacement. There are two other
fields in /proc/stat, however, which tell me, according to the man page,
"The number of swap pages that have been brought in and out". Can anyone
tell me what that means? It sounds to me like this might be something
that I'm more interested in--my guess is that it means pages that have
been brought in off of the swap device, which would, I assume, mean
pages that have been swapped out when the system ran out of free frames.
Although I'm still not quite sure what is meant by the field, because
systems that have not experienced any high memory loads still say that
they have paged "swap pages" in and out.
Any help given would be sincerely appreciated.

The first time I tried it, I had all the phones disconnected, and the modem
plugged into the basement connector. which is connected to the phone box at
home. There's no jack in it. just wires going in and out of it.
I also tried it with all phones connected through the filters and moving the
modem about. The transfer rate is the same whether it is in the basement or
in my room .
Another thing:
I am on the 64.229.x.x network. I heard some negative references to this ,
and am wondering : Would it be that I am connected through a bad card to a
worse front end ?
