• How do I find where a ruby method is declared?

  - by Joe Fair

  I have a ruby method (deactivate!) that is on an activeRecord class. However, I can't seem to find where that method is declared. There have been numerous developers on this project, so it could be anywhere. There is a deactivate! on an unrelated class, but it doesn't seem to get called. Any ideas how to find all the superclasses for an instace, or where to find the code for deactivate!?

• Optimizing division/exponential calculation

  - by Saltheart

  I've inherited a Visual Studio/VB.Net numerical simulation project that has a likely inefficient calculation. Profiling indicates that the function is called a lot (1 million times plus) and spends about 50% of the overall calculation within this function. Here is the problematic portion Result = (A * (E ^ C)) / (D ^ C * B) (where A-C are local double variables and D & E global double variables) Result is then compared to a threshold which might have additional improvements as well, but I'll leave them another day any thoughts or help would be appreciated Steve
