I just had to rebuild my raspberry pi again. It seems to keep eating its sd card for some reason. I decided to forgo the gui this time since it's a headless server. I just access it via ssh and vnc and I think I'm ready to drop vnc. Generally all I use X for is editing files in leafpad, and I can just as easily run pluma locally and connect over sshfs.

I have a pretty simple wireless setup - an open wireless network with no keys or certificates (I live on a farm, I'm not concerned...

When I first bought my current workstation (currently running Wheezy) several years ago, I got a base station that featured two DVI ports and a VGA port. "Hot Dog" I thought, "I can plug three monitors into the back of this thing, one into the side, and with the laptop screen I can have up to 5 monitors on my workstation!" Imagine my disappointment when as soon as I plugged in the second DVI monitor, the display on the laptop screen disappeared. I was really looking forward to...

Gnome 2/MATE leave message

Posted 09-04-2013 at 11:18 AM by drask

WiringPi-Perl example

Wheezy annoyances

Well, since Wheezy officially came out a couple of weeks ago, I decided to upgrade my squeeze install this weekend. Upgrading worked pretty well overall, but I'm left with a bunch of little annoyances that leave me wondering if I should just put up with them or reinstall. I'm wondering if anyone out there has fixed any of these.
