Why, thanks for the pointer -- I'm particularly proud of having written
"""
The only really workable way to develop large software projects, just as
the only really workable way to run a large business, is a state of
controlled chaos.
"""
*before* I had read Brown and Eisenhardt's "Competing on the Edge:
Strategy as Structured Chaos" (at that time I had no real-world interest
in strategically managing a large business -- it was based on mere
intellectual curiosity and extrapolation that I wrote "controlled chaos"
where B & E have "structured chaos" so well and clearly explained;-).

BTW, if you want to read my entire post on that Austrian server, the
most direct URL is
