GUI Interacitve

Posted 05-04-2012 at 11:06 AM by rainbowsally

This will be a new subtheme under the GUI Programming topic.

No examples or experiments yet, let's just talk about the how's and why's of doing this.

It's time to start thinking about an interactive layer to communicate with the GUI system. This implies an interpreter, which runs in a loop grabbing commands and executing them (if the syntax is correct) and is really not much different from a bytecode compiler which runs an execution loop to do the same, so we can do...

Integrated KVM connector

Posted 05-02-2012 at 09:09 PM by Skaperen

We need a standardized integrated connector that supports ALL of the following in one connector:

1. Dual DVI data links for video up to 2560x1600
2. Single VGA compatible analog signal likes (as in DVI-A)
3. PS/2 keyboard connection
4. PS/2 mouse connection
5. USB

Then maybe the KVM switch market can get their act together.
