factorials

inspired by albert's experiments I took his script, changed it a bit [0], & calculated the factorial of 30.000 on my two boxen.

results:
  • belanna: 46 seconds
  • nerys: 56 seconds
update 1: good old guinan needs 5 minutes & 3 seconds; still faster than chrisu's desktop machine :-)
& on our colleen the script takes 1 minute & 22 seconds to complete.

update 2: the new guinan takes 1 minute & 48 seconds. wow.

#!/bin/sh
[ "$#" != "1" ] && echo "Usage: $0 integer" && exit 1
STARTDATE=$(date)
echo "
define fac (x)
{
        res = 1
        while (x > 1)
        {
                res *=x;
                x -= 1;
        }
        return res;
}
fac ($1)
" | bc
ENDDATE=$(date)
echo "start: $STARTDATE"
echo "end: $ENDDATE"
exit 0

forcing xserver-xorg-video-intel

if you have an intel graphic card & you are using the new intel X.org driver [0] instead of the old i810 one you might — like me — get the following errors in your /var/log/Xorg.0.log & only some strange resolutions:
(EE) intel(0): detecting sil164
(EE) intel(0): Unable to read from DVOI2C_E Slave 112.
(EE) intel(0): Unable to read from DVOI2C_E Slave 236.
(EE) intel(0): ivch: Unable to read register 0x00 from DVOI2C_B:04.
(EE) intel(0): Unable to read from DVOI2C_E Slave 112.
(EE) intel(0): tfp410 not detected got VID FFFFFFFF: from DVOI2C_E Slave 112.
(EE) AIGLX: Screen 0 is not DRI capable
the information in #434028 lead me to the following entries in my /etc/X11/xorg.conf:
Section "Monitor"
        ...
        # gtf 1280 1024 75
        # 1280x1024 @ 75.00 Hz (GTF) hsync: 80.17 kHz; pclk: 138.54 MHz
        Modeline "1280x1024_75.00"  138.54  1280 1368 1504 1728  1024 1025 1028
        Option          "PreferredMode" "1280x1024_75.00"
EndSection
& now my monitor is running on 1280x1024 again.

you might want to auto-adjust your monitor afterwards with the test image from nies.ch.

moving

no, it's not me who is moving but my mother.

she got the keys for her new apartment in innsbruck exactly 4 weeks ago. today (finally!) she received the notice from the local court that the property transfer of her house in telfs to the new owner has been finished, & simultaneously his money arrived on her bank account.

so I drove her & her last few belongings to innsbruck in the afternoon, & the chapter "telfs" is (almost, some bureaucracy is still missing) over.
