VCALC and crowd-sourcing to build a coding for community culture: nifty tools and assignments

vCalc is a crowd-sourcing programming platform to create and share free calculators in an on-line encyclopedia at vCalc.com. Using vCalc, programmers can develop formulas and algorithms in a private library. They can also use their own private library or any of vCalc's public library of 8,000+ formulas to create calculators that are available on the web or via free Apple or Android apps.
