I come from a background of Delphi development, and came
across this article by Steve Trefethen about The Delphi
R&D Development Process…

Interesting to note that the Delphi IDE builds in only 20
mins….Even more interesting is the fact that all of borland’s tools
(both internal and some external) are written in Delphi…..Hopefully one
day they’ll fix up the Delphi product line and make the IDE actually functional
and productive….compared to VS.NET, unfortunately Borland have a long way
to go just yet…
