Hi David,

I was completely mislead by "broadcast". Hardware guy :-))

But whether you use announcements or the ages old dependency mechanism (look for changed and update and friends) it means you first will have to register to receive the updates, announcements, events ...

Later some object will just iterate over your collection. Usually using a framework tends to slow things down a bit but makes things clearer if the framework is the right choice for your task.

But go for clarity first then use the profiler then optimise. Sounds like I'm repeating Casey here. Well, it's worth repeating :-)

Cheers

Herbert

Hello William,

there is a book named "Learn programming with robots" which is aimed at teaching programming with Squeak. The book can be obtained via Amazon and google turned up this page for download. https://gforge.inria.fr/frs/download.php/10764/BotsInc-OriginalEnglish.pdf

Then there is Squeak by example which is meant to teach Squeak but assumes some programming experience.

In both cases find the accompanying Squeak images. This is because Squeak evolves and for newcomers it's important that the examples just work. Although finding out why an example did not work is a great learning achievement people are usually good at providing enough not working examples for themselves. :-)

The site Casey recommended is a great resource, it can be found here. http://stephane.ducasse.free.fr/FreeBooks.html

But you have to be a bit careful because of the differences in Smalltalk dialects. Which means not every example will work unmodified in a current Squeak image.

Other than that there are Etoys and Scratch which are based on Squeak but provide a graphical introduction (tile programming) into programming.

And finding an answer to Casey's question, a project that interests you, may get you some more results.

Cheers,

Herbert

Hello,

If I have never programmed before but want to learn to program with Squeak, which tutorial should I read?

Thank you,

Will
