VBoxHeadless - VM without GUI

Fellow Geeks,
I have been doing some interesting stuff of late and thought i should share some...

I probably should start with the simplest....

To run a VirtualBox Virtual Machine without GUI on the Host (This is default in CentOS' and Fedora's Virtual Machine Manager) for whatever reason u may use any of the following commands...

VBoxManage startvm "VM name" --type headless

or

VBoxHeadless --startvm

Typical scenario in production/server environments where no one needs to access the GUI of a Virtual Machine from the Server/Host itself.
Instead we access the VMs using VNC or SSH

Impossible Objects

"An impossible object (also known as an impossible figure or an undecidable figure) is a type of optical illusion consisting of a two-dimensional figure which is instantly and subconsciously interpreted by the visual system as representing a projection of a three-dimensional object although it is not actually possible for such an object to exist (at least not in the form interpreted by the visual system)." - Wikipedia

Impossible Fence

Is this even possible ? [its the shadows doing the trick]

What a world of impossibility....what about the other guys in the swimming pool ?

Great work with drawing...

This is easy

Yet Another impossible fence

Optical slash Visual illusions

The two circles seem to move when the viewer's head is moving forwards and backwards while looking at the black dot.

The horizontal lines are parallel, even if they seem otherwise.

Can u see black (not white) dots at the intersections?

The two orange circles are the same size.

Duck or Rabbit ?

This is a flower vase (or is it a two-silhouette profile?)

Are they spinning or not ?

Windows Embarassing itself

I have used Windows but never became a fun of that OS.
If the GUI can embarass itself that much what about the things u dont see ?
And dont forget u will never get any where close to its Source Code...

The logical conclusion

Windows Sucks

1.
This is Linux land. In silent nights you can hear the Windows machines rebooting.

2.
The box said "Windows 98 or better" - so I installed Linux

3.
Macs are for those who don't want to know why their computer works.
Linux is for those who want to know why their computer works.
DOS is for those who want to know why their computer doesn't work.
Windows is for those who don't want to know why their computer doesn't work.

# McAfee-Question: Is Windows a virus ?
No, Windows is not a virus. Here's what viruses do:

1. They replicate quickly - okay, Windows does that.
2. Viruses use up valuable system resources, slowing down the system as they do so - okay, Windows does that.
3. Viruses will, from time to time, trash your hard disk - okay, Windows does that too.
4. Viruses are usually carried, unknown to the user, along with valuable programs and systems. Sigh... Windows does that, too.
5. Viruses will occasionally make the user suspect their system is too slow (see 2.) and the user will buy new hardware. Yup, that's with Windows, too.

Until now it seems Windows is a virus but there are fundamental differences:
Viruses are well supported by their authors, are running on most systems, their program code is fast, compact and efficient and they tend to become more sophisticated as they mature.
So Windows is not a virus. It's a bug.
