Adél évnyitója augusztus 31-én, kedden lesz. Ma, vasárnap este, megtöltöttem a Schultütéjét, amit holnap viszünk be az iskolába.
First you need a script which can suspend your machine from the command line:
me@kv-laptop:~$ cat /usr/bin/power-cmd
#!/bin/bash
# gnome-power-cmd replacement

echo Usage: $0 ‘<suspend |hibernate>’
exit 1

esac
Then you need a script which records music player status (I use Audacious and Radiotray):
me@kv-laptop:~$ cat .bin/paactivity
#!/bin/bash
export DISPLAY=:0
pacmd list-clients | egrep -i “radiot” > /dev/null
RADIO=$?
audtool2 playback-playing
AUDA=$?
echo “radio: $RADIO auda: $AUDA” > /tmp/lastrun
if [ $AUDA -eq 1 ] && [ $RADIO -eq 1 ];
then
rm /tmp/.active-audio
else
touch /tmp/.active-audio
fi
You have to put this sctipt into your crontab. (crontab -e -> */2 * * * * /path_to/paactivity)
Then you need to start xautolock at login (apt-get install xautolock):
me@kv-laptop:~$ cat .bin/inactivity
#!/bin/bash
exec xautolock -time 8 -locker “if [ ! -e /tmp/.active-audio ] ; then /usr/bin/power-cmd suspend; fi”
And finally you need to configure Gnome to start this at login, (Settings/Preferences/Startup Applications/New -> /path_to/inactivity).
Working with Postgres is always fun — it has soul.
I had to fix recently a broken PostgreSQL install on a Windows 2003 Server. I don’t really know how it was installed, but I was told that according the Postges forums, it has know issues:
The install fails with ‘error reading file %path%\postgresql.conf’. It doesn’t write to anything in the postgresql data directory or create the postgresql service. We have made postgres user Administrator, explicitly given it full control permissions to temp directories, ownership to the install directory, installed when logging on as the postgres user. We last tried to create the service manually, and even that fails: service is created but will not run.
When I logged in to the system the first suspicious things was that we had two data directories [Drive:]\PostgreSQL\8.4\data and [Drive:]\PostgreSQL\data — of course one of them wasn’t necessary.
The solution was:
That’s all folks!
not bad — via konzanarch
elementary nautilus (via lifehacker): this makes it a bit easier to use
sudo add-apt-repository ppa:am-monkeyd/nautilus-elementary-ppa
sudo apt-get update && sudo apt-get upgrade
ubuntu tweaks: this is almost windoz
sudo add-apt-repository ppa:tulatrix/ppa
sudo apt-get update && sudo apt-get install ubuntu-tweak
shotwell (via fedora 13): this one looks promising
sudo apt-get install shotwell
