I used ruby/gtk/glade for project 6. I was surprised how easy it is to use Glade (especially version 3) to design GUIs for Linux.
One of the hardest things I ran into was trying to figure our how to get images to show up in gtk. It ended up not being too complicated, I had to do something like gtk_image.buffer = Pixbuff.new().
I'm surprised that lab 5 started working, because I was not able to access the images I uploaded before, but I guess it's working now. Not sure why.
