How to obtain the result of a chemical reaction given two components?
For example, I enter "N2 + H2" and it gives me "N2 + H2 → NH3". Or "C10H8 + O2" and it shows "C10H8 + O2 → CO2 + H2O". I don't need coefficient calculator, where I type full reaction and it calculates coefficients (marked bold in next example): C10H8 + 12 O2 = 10 CO2 + 4 H2O.

How does one make Evolution work with Exchange 2010?

Better way to do "echo $x | sed ..." and "echo $x | grep ..."
