Qi 6.1 came online in
April 2005, many people have shown interest in developing Qi for many different
applications. The online text Functional Programming in Qi was designed as a
language standard; it answers a lot of questions and is rich in code
studies, but FPQi does not attempt to cover everything
that can be done in Qi. As Wittgenstein wrote in the Tractatus,
"What we cannot speak
of we must pass over in silence."
My lips are not as tightly sealed as Wittgenstein's. This page is a
portal to a series of practical essays on various parts of computer
science. I say 'practical' because the essays are copiously illustrated
in code. All the studies are fairly short (a few sides) and the programs
are also short (generally < 70 lines). Apart from anything, I like
short examples! A lot of this stuff is unfinished. This is deliberate. A
good friend of mine had a saying
"Software is never
finished, its just abandoned."
This is true here. Part of the reason is that I want to encourage you
to take these ideas further and improve them. They are a first word, not
the only word, and certainly not the last word. The programs do work and
they are very short and they are designed for you to mess around with
them. Per ardua ad astra, we
progress to the heavens by self-expression and doing our own thing. So
mess around with these programs as much as you like.
I'd also like to say that I enjoyed writing this stuff - much more so
than that parody of human creativity - the scientific paper. I hope you
enjoy them too.
