[Self-interest] UK Smalltalk User Group Meeting - Wednesday, September 29th 2021

The next meeting of the UK Smalltalk User Group will be on Wednesday,
September 29th.

For this month's meeting, we take a look at an example of an application
written in Smalltalk. Specifically, one that fits in a cultural tradition
that is as old as Smalltalk itself, if not older: that of using computers
as tools to teach powerful ideas and to augment thinking.

Dr. Geo ( http://drgeo.eu/ ) is an interactive geometry software with
programming capabilities in Smalltalk.
Dr. Geo aims to be an open, easy to study, modify and extend interactive
geometry software. Ten years old kids use Dr. Geo to explore Euclidean
geometric sketches; agile kids extend and program it with its embedded
dynamic Pharo language and user interface.

Hilaire Fernandes started the development of Dr. Geo in 1996. In 1998, he
ported it to GNU/Linux at a time where no interactive geometry software
existed on this system. It latter became officially a GNU application
blessed by Richard Stallman. In the spirit of free software and access to
source code, Dr. Geo integrated scripting and programmed figure as well as
code introspection from the application itself in an interactive
programming environment.

Hilaire currently teaches in a junior high school in Geneva where he uses
Dr. Geo to teach mathematics (geometry) and basic programming.

This will be an online meeting from home.

If you'd like to join us, please sign up in advance on the meeting's Meetup
