how to read the database of sleep cycle and how to generate the same plots

1) copy the file /var/mobile/Applications/sleep cycle/Documents/eventlog.sqlite
to your pc.
2) use sqlitebrowser to open the file and to extract the data:
ZINTENSITY contains the data
ZTIME contains the time
ZSLEEPSESSION contains the session number (number of night)
-> the time is given in seconds since 1.1.1970
-> example: array=dblarr(2,200)
array(0,*)=ZTIME
array(1,*)=ZINTENSITY
3) for plotting:
->subtract the time of the first element from all times (remove the time offset)
array(0,*)=array(0,0)
->generate an empty array with the same number of elements as you have seconds
arind=fltarr(max(array(0,*)))
->put your data to that positions where the time was recorded.
arind(array(0,*))=array(1,*)
-> plot the data with plot,smooth(smooth(smooth(at,1001),1001),1001)

use mouse gestures in fvwm2/suse

easystroke is a wonderful program that lets you record mouse gestures and executes
commands based on them.
In conjunction with a special definition in .fvwm2rc you can specify any action
to be executed. For example to switch to a special window on the desktop:
in .fvwm2rc:
Key Pause A N FocusWindowNumber 8
-> switches to the window remembered on position 8
PipeRead 'for i in `seq 0 9`; do echo Key $i A MC AssignNumberToCurrentWindow $i; done'
->remembers the window and stores it on position 8

in easystroke define key "Pause" to a gesture of your choice.

If executing that gesture the window 8 is switched to.

wacom bamboo stops working after unplugging

to solve this (to get it working as a graphic tablet again without restarting X) just switch from X11 to Console (press Ctrl + Alt + F1 together then release them) and then switch back to X11 (press Ctrl + Alt + F7 together then release them).
Then the graphic tablet works as before unplugging!

that's it.

set up firewall to allow only one ip address

iptables -F
iptables -P INPUT DROP
iptables -P FORWARD DROP
iptables -P OUTPUT ACCEPT
iptables -A INPUT -i lo -j ACCEPT
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -L -v

iptables-save
rcSuSEfirewall2 restart

do not forget to start firewall automatically
