http://www.logilab.org/narval/ looks very interesting. It's a framework for building intelligent agents. also http://ai.eecs.umich.edu/soar/ looks more fully-developed.

http://www.teresaudio.com/memtest86/ is a standalone memory tester.

You can put it on a floppy or to add to lilo put memtest86 (the binary) in /boot and just add this to /etc/lilo.conf:

image=/boot/memtest86
label=memtest

Backspace and delete seem to give me problems. The config that seems to work for me (using Gnome terminal) is to select the "Swap Delete/Backspace" option and don't select the "Delete generates DEL/^H" option.

I had a strange problem with Java - JBoss could start up but not shut down. It hung after shutting down the mail service but before any JMX RMI messages. Turns out that I had moved my machine and the network config was FUBAR: my hostname's entry in /etc/hosts didn't match any of the IP's that I had configured. D'oh!

postgres' nightly maintenance was emitting:

NOTICE:  RegisterSharedInvalid: SI buffer overflow
NOTICE:  InvalidateSharedInvalid: cache state reset
NOTICE:  RegisterSharedInvalid: SI buffer overflow
NOTICE:  InvalidateSharedInvalid: cache state reset
NOTICE:  RegisterSharedInvalid: SI buffer overflow
NOTICE:  InvalidateSharedInvalid: cache state reset

A note on one of the mailing lists indicates that this can happen if someone has an open transaction. In my case bouncing tomcat did the trick.

It took a little bit of fiddling to get my Gateway computer's MS IntelliMouse 1.2A to work with both GPM and X, but in the end the config is pretty straigtforward. /etc/gpmdata looks like:

device=/dev/psaux
responsiveness=
type=imps2
repeat_type=raw
append=""

which ends up running gpm like so: /usr/sbin/gpm -m /dev/psaux -t imps2 -Rraw .

X's XF86Config "Pointer" section looks like:

Section "Pointer"
   Protocol        "IMPS/2"
   Device          "/dev/gpmdata"
   Buttons         3
   Emulate3Buttons
EndSection

NOTE: I don't have the mouse wheel working (yet).

The pass-through device for GPM is /dev/gpmdata.

The Tulip network driver 0.92 on my Gateway box would stop working, usually when I was sending a large block of data. It would put this in the log:

Jun  4 19:30:29 tobypc kernel: eth0: Transmit timed out, status fc664010, CSR12 00000000, resetting...
Jun  4 19:31:04 tobypc last message repeated 7 times

Upgrading to version 0.92t seems to have fixed things.
