Not the way I write it. In fact, my Perl looks a lot like C in terms
of how it's structured. Perl need not be obfuscated.

C since '83 (PC-DOS 2.0), UNIX since '85 (on a PDP-11).

C was invented to implement UNIX.

I wrote a gear calculator in C back around 1987.

Combining cycling and informatics looks interesting to me as well.
It would be nice if you could get speed, position, cadence, heart
rate, position and weather data into the same log with camera
footage. I bet the technological basis is there, but we'd need
more open interfaces from the gadget vendors and probably also
some formal industry standards for that to come about. Think about
the Internet, it would never have gone this far without lots and
lots of those.

I guess the Dutch ANWB could well provide GPS coordinates and even
some online images for their navigation points in 5 years or so

If the open platforms were there, you could easily just go ride
and at home with a few mouseclicks, you'd share your route with
others...

Drat. I was going to try that project...

I don't know where it is. It only did simple ratios to help me find
duplicates. I haven't used it in years. Sheldon's web based calculator
is better anyway with different types of gear measurments and lots of
standard cassettes and freewheels pre-programmed into it.

Yeah, Sheldon's is where I got the idea, when
I found myself spending hours repeatedly
running different combinations through it and
decided I'd like to write a program to do all
the combinations I'd want AND show some
additional data...

Sure, would make statistical research quite a bit easier :-)
