Kaufabratung: WMF LONO Filterkaffeemaschine mit Thermoskanne

Wir haben uns zur Hochzeit eine LONO Filterkaffeemaschine mit Thermoskanne von WMF schenken lassen. Leider taugt die Kaffeemaschine gar nichts. Sie sieht zwar schön aus mit ihrem Chromangan, aber sie kleckert so massiv beim gießen, dasss man sie keinem Gast in die Hand geben mag. Außerdem hält die Thermoskanne nicht war. Die Kanne wird sogar relativ warm von außen. WMF werde ich mir wohl nie wieder kaufen. Ziemlich peinlich...

It worked for my setup.

Gnucash sound

My monitor makes this annoying sound during my work with gnucash:
I think the sounds depends on the multiple horizontal lines shown by gnucash:

Interestingly i see peaks in the sound specturm at 3500, 7000 and 14000 Hz.

Maybe any technician can explain this phenomenon to me.

Technical details:

3200x1080px
96x96 dots per inch
Depth 24
GPU GeForce GTX 680
Display FUS L19-5 (DFP-3), Ancor Communications Inc ASUS VE276 (DFP-0)
Linux version 3.5.0-43-generic (buildd@panlong) (gcc version 4.7.2 (Ubuntu/Linaro 4.7.2-2ubuntu1) ) #66-Ubuntu SMP Wed Oct 23 12:01:49 UTC 2013
