3/17    I've read about research on GUIs that uses 3D and circular menus
        instead of the horizontal pulldown at the top of every app.  Anybody
        know where I can get trial software like that?  Experimental 3D
        window managers etc?
        \_ If you're interested in circular (pie) menus, take a look at:
           http://www.catalog.com/hopkins/piemenus/index.html
           . . . links to references on pie menus, window managers using
           pie menus, an ActiveX pie menu control, and much more.  I don't
           know anything about 3-D window managers, though.  -- kahogan

5/20    Linux question.  my laptop has a Nvidia 8400M GS chipset.  For a
        while I was excited about the fact that Nvidia actually has
        Linux driver for such.  But after I used it for about 2-3
        weeks, I realize that this Nvidia driver is the reason why my
        Ubuntu is keep crashing.  I would like to swtich to a
        open-source driver, idealy, capable of leveraging some degree

6/8     hey nerds, Virtualbox is totally awesome.  My host OS is
        current ubuntu, I'm running Windows as my guestos, I can transfer
        files, copy/paste, all of that crap
        \_ Cool, I was thinking of looking into this soon.  How well does
           it work?  Can I run most windows programs pretty well?  ActiveX?
           Games?

        \_ This is a really cool project. Will they someday also print the
           circuit boards they need to run it?

4/8     What defines upper class, middle class, and lower class? Income?
        Post tax income? Post tax deduction income? How about asset and
        liabilities? I mean, don't most homeowners with mortgages have
        LIABILITIES since they OWE money? If we count mortgage and
        credit card debts, wouldn't most Americans be lower class?

3/28    After almost a decade of not using windows I'm thinking about getting
        a cheap windows computer.  Security wise what are some musts?

Pie Menus are a naturally efficient user interface technique: directional selection of pie slice shaped targets. The cursor starts out in the center of the pie, so all targets are large, nearby, and in different directions. Fitts' Law explains the advantages of pie menus, relating fast selection speed and low error rate to large target size and small distance. Pie menus are easy for novice users, who just follow the directions, and efficient for experienced users, who can quickly "mouse ahead" once they know the way.
