Gnome 3 Extension: System Monitor

I was missing a system monitor icon from the previous release of Gnome and finally had the time to look for a replacement in Gnome 3.
Go to the extension page with your favorite browser.
Install and enable the extension turning the button in the top left corner on.
Don't forget to configure the icon position clicking on the configure button or you'll find the calendar icon squeezed on the right and unreadable.

Fedora 17 Microphone not Working

If you can't use your headphones microphone on your newly installed Fedora 17 device, you first need to:

1. Open your sound settings and check the proper  device is enabled.
2. If yes, run alsamixer, select the sound card and make sure that the internal microphone and capture are enabled and that both Mic Boost and Capture have high volumes.
3. Run arecord -D "hw:1,0,0" -f cd -d 4 test-mic.wav. The wav file created should have sound in it.
