Lisp-y Data Abstraction in Forth - Brad
Nelson "Back in
February
2019, I explored how Forth can tackle Structure and Interpretation of
Computer Programs (SICP)
style data abstraction over rational numbers, complex numbers, and polynomials.
However, in the interest of time, I left out the implementation of a garbage
collector (instead leaking like a sieve). I'll now correct that omission,
demonstrating a Cheney collector
in Forth and how to make closures that don't leak memory."

Programming Challenge: Palindromic Numbers - Bill
Ragsdale Palindromic Numbers are those whose digits are the same forward
and backward as for RADAR but with numbers - such as 88 and 666 and 12321.
Program a generator or a filter to find the palindromic integers from, say the
five digit 00000 to 99999. Over this range, what is the percentage of
palindromic integers? Why?

Scamp - An Off-the-shelf Forth Computer for Embedded
Applications - John Catsoulis Scamp is a small embedded machine
that comes with FlashForth preinstalled. Its intended to make it easy for
beginners to learn Forth in an embedded context, and to be a turnkey Forth
computer for experienced engineers. This talk will provide an overview and demo
of Scamp.
