Farmvill can be a fun way to pass some time, but if your fields get to be a bit big clicking on every single field can get to be a bit tiresome. I found this autohotkey script in the depths of the internet. It simplifies the process greatly

Autohotkey, Farmville, Script

Sometimes it is useful to switch into the directory of the script e.g. when we need to call or include further files and don’t want to go through the hassle of searching for the script in the file system. Especially when symlinks are involved everything get a bit more interesting. This little snippet switches into the directory of the script, using readlink to dereference symlinks if the script is called via a symlink.

## a small snippet to switch into script directory
02
SCRIPTDIR=${0}
03
if [[ -L ${SCRIPTDIR} ]]
04
then
05
# dereference the symlink
06
SCRIPTDIR="$(readlink -e ${0})"
07
fi
08
# chop off the scriptname and switch into the directory
09
cd ${SCRIPTDIR%/*}

Today I ran into any old problem: you have a script that should do something when it recieves a signal (e.g. if someone sends it USR1 it should write to a log/syslog), but the script uses a long sleep because it normally only checks/calculates stuff every x min. If you send it a kill -USR1 $pid it will normally execute the trap AFTER the sleep is done, not so great. I figured of the following solution today: put the sleep in a while loop that checks if the full time was slept, and inside the loop a sleep that sleeps the X seconds remaing in the background followed by a wait.

If the script now recieves a USR1 it can kill the wait, execute the trap and will continue the remaining sleep on the next iteration of the loop.

I made some of my cookies this evening and used the opportunity to take some pictures. The lighting wasn’t perfect, so everything has a slight yellow tint. I decided to leave the pictures that way instead of trying to correct the problem in Photoshop.

Server was down for the last 6 hours due to me updating a few stuff that really really didn’t work out too well (grub, xen and kernel at the same time). I gave up and afer a few hours of work managed to revert back to the old configuration so I can recieve mail again till I figure out what went wrong. Server may be down tomorrow a bit too while I try to figure out what exactly broke and try to at least get grub and xen updated.

I had Monday off work, so we went hiking in the Black Forest (southern Germany) the last 3 days. The first day we started hiking around Blumberg (I managed to twist my knee after a few km, didn’t really make things easier), then we took a steam locomotive (Sauschwänzlebahn) up the hill and hiked back to the car. Afterwards we drove up to Titisee where we booked a hotel for 2 nights.

The next day we drove over to the Wutachschlucht and hiked a very nice trail. Since the weather was good and it was a Sunday there were a decent amount of people hiking. In the late afternoon we finally arrived at our destination, sat down and rested our feet before we took a bus back to where we parked the car.

On the last day we were a bit tired for hiking the last 2 days and the weather was getting  a bit rainy, so we decided to take the scenic route home, and stop by waterfalls and ruins on the way.
