Screen Capture With Mac Keyboard and Windows Desktop

The problem starts on the Mac keyboard: you don't have the prnscr key! But still what you have is a Windoz machine. What is working for me (there are external applications but I couldn't find a good free one) is to open the on-screen keyboard under Programs --> Accessories --> Accessibility. There you have it!
If you have the always-on-top option enabled, you loose control of the physical keyboard and sometimes I had to kill the virtual thing anyway to get back the other one. But I can live with that.

gpk-application Not Working

I recently had this problem with the gpk-application on a Fedora 9. This Gnome application allows you to check what you have installed and install/remove packages.
The thing was I could not see the groups of packages and update the list from a remote machine. It happened I found out the cache was corrupted and this command:

> yum makecache

restored it to its full functionality.
Almost. I still cannot remotely refresh the list (which I could on the local display) but I think this is another story... permissions maybe.

Linux Graphical FTP Client

I recently switched to gFTP, the FTP client from Gnome, after I apparently encountered problems connecting to a couple sites with Kasablanca (from KDE). One was that the client could not display the content of a remote directory no matter what I did.
I must say that gFTP is more solid and it did not have those glitches. I personally recommend it at this time.
