Re: Cannot get hdmi output to work on screens below 1000 Eur

It's also possible that none of those auto switch between inputs, especially if you had VGA going into them too. Unlikely I'll grant you but possible. So have a look in the screens menus to see if you can set it to DVI

Re: Turbo Clocks with lower Core Clock

What is your server doing? To say that servers in general don't need high CPU is a bit of a sweeping statement. I'm not saying that in your case it isn't accurate, but the chances are that for most processes extra CPU on demand would be a good thing. This includes things like file copying, people h...

This is more like a USB monitor. You connect it to the USB port and that's how the picture information is sent. Requires a driver obviously and isn't very fast with refreshes but it works. A lot of digital photo frames have it as a capability

Re: Stream to or control of an Apple TV?!

Well if you jailbreak your ATV, you could install XBMC and then use it's web server to make it play stuff, assuming you have an older ATV2 not the newer ATV3 (you mention rev 2 so I'm assuming you have).

Re: Bricked my RPi running rpi-update

Can I ask why you're using rpi-update?

Raspbian will update the firmware and kernel happily using apt. If you want to be bleeding edge you can add the untested branch to your apt sources and then you'll be using the latest kernel and firmware just like you would with rpi-update

well sudo apt-get update followed by sudo apt-get upgrade would be the place to start.

Yup, if it's really an embedded system with no user interaction a read only filesystem is the only option (that's what other embedded linux setups do), however it's a non-trivial job to get a working linux system with a read only file system. You also want the smallest system possible so remove as m...

The answer is basically, "You're doing it wrong" The Raspberrypi is a running a full OS. This comes with all the restrictions of that, including requiring clean shutdowns.

vi has two modes, insert and command mode, you need to press i to get into insert mode.

You're better off replacing vi with nano whenever you see it in an example as nano will work as you expect for a text editor
