    One of my favorite incidents happened over 10 years ago when computers were much less powerful. An engineer came to me with a financial forecast spread sheet that was taking 4-6 hours to run. After speaking with him about what he was attempting to accomplish, I rewrote his application in FORTRAN (the engineering language of choice at that time) and he was able to do an analysis in 6 seconds! That is not a misprint. This engineer was intimately familiar with spread sheets, his only tool was a hammer, so everything looked like a nail.

        I'm going through the same thing now, inherited a bunch of Excel "reports" to maintain. Oh, the horror! -- modified at 20:29 Monday 5th March, 2007 Oh, and... every tool is a hammer.

          VBA/Excel03 still has the same performance penalties over modern languages. >30min to ~1s (timed from button click to completed dialog appeared, so a decent chunk of that second was form loading) X|
