Seems to me that Moore and Rather used Moore's FORTH at the National Radio Astronomy Observatory before they started Forth Inc. So you might say that FORTH is a 'natural' for Astronomy! --hsm On Wed, Nov 14, 2012 at 6:00 AM, Dmitry Pavlov wrote: > Hendrik, > > > Is it conceivable that you need

As much as I love Racket, there are certainly times I miss 'C' and it's ability to write code pretty much in assembler. As co-creator of the first commercial fractal generation software (FracTools, FracInt was free not commercial) I found the need to code down to the bare metal and a bit beyond cha
