„Inside every large problem is a small problem
struggling to get out.“
                             - Hoare’s Law of Large Programs
„Work expands so as to fill the time available
for its completion.“
                                      - Parkinson’s Law
„Any piece of software reflects the
organizational structure that produced it.“
                                       - Conway’s Law
„There are three kinds of men: The ones that
learn by reading. The few who learn by obser-
vation. The rest of them have to pee on the
electric fence.“
                                      - Will Rogers
„You cannot reduce the complexity of a given
task beyond a certain point. Once you’ve
reached that point, you can only shift the
burden around.“
                       - Tesler’s Law of Conservation as Complexity
„Adding manpower to a late software project
makes it even later.“
                         - Tesler’s Law of Conservation as Complexity



„Adding accessibility to a late project makes it
even laterer.“
                                                                -Me
„The single biggest problem in communica-
tion is the illusion that it has taken place.“
                                    - George Bernard Shaw
„The first 90% of the code accounts for the
first 90% of the development time. The
remaining 10% of the code accounts for the
other 90% of the development time.“
                                   - Ninety-ninety Law
„A task always takes longer than you expect,
even when you take into account Hofstadter’s
Law.“
                                   - Hofstadter’s Law
„People under time pressure
don’t think faster.“
                              - Lister’s Law
„Whatever the state of a project, the time a
project-leader will estimate for completion
is constant.“
                                       - Hartree’s Law
„We can make a Web site work with zero
hearing. We can make one work with zero
vision. We can even make a Web site work
with almost zero movement. But we can’t
make a Web site work with zero cognition.“
                          – Joe Clark, @media conference 2007
„The explanation requiring the fewest
assumptions is most likely to be correct.“
                                      - Occam’s Razor
„The only way of discovering the limits
of the possible is to venture a little way
past them into the impossible.“
                                      - Clarke’s Second Law
