My personal thoughts is yes two monitors are necessary. It is very useful to have log windows open on one monitors and code on another. It is just like the real world the larger desk the more you spread things, and in my world it is easier to organize my work flow with things spread out where i can see them.

I am looking for a virus that i can infect the lab computers (only connected to local network no outside network connection) with that would be easy for the students to remove by hand. Can the Slashdot community point me any directions, is there an executable out there what would work ( this scares me), or do I try to write one my self, or is there one that is written that i can compile my self?

To generate the clean hydrogen, researchers produced a new type of zinc oxide crystals that absorb vibrations when placed in water. The vibrations cause the crystals to develop areas with strong positive and negative charges–a reaction that rips the surrounding water molecules and releases hydrogen and oxygen. The mechanism, dubbed the piezoelectrochemical effect, converts 18% of energy from vibrations into hydrogen gas (compared to 10% from conventional piezoelectric materials), and since any vibration can produce the effect, the system could one day be used to generate power from anything that produces noise — cars whizzing by on the highway, crashing waves in the ocean, or planes landing at an airport.
