Greetings, Linux Newsletter subscribers.

It's Monday again, and receiving this message means that you have agreed
to read every link in this newsletter twice. Ready? Go!

Virtualization is nifty. Managing polite fictions is much easier than
managing physically real items--at least until things get complicated. Though you
have to build physical robots or hire interns to manage real machines,
virtualized machines have one strong advantage: you can use other software to manage
them. Kris Buytaert introduces openQRM, a software project to create and manage
virtual images on real machines.

Visualization is nifty. (Usually lede opening sentences aren't this
parallel. Editors take the joys they can get.) Choosing the right type of graph can
make data trends jump out at you. Raju Varghese recently had to track down some
odd behavior on his web servers. With a little cleverness, he produced 3D
graphs of traffic and tracked down the trouble. Here's how you can do the same:
