My favorite one is "Smalltalk by example" located at http://www.iam.unibe.ch/~ducasse/FreeBooks.html <http://www.iam.unibe.ch/%7Educasse/FreeBooks.html> Just read it, and wow, it's great I think! (Yeah, a bit outdated, from 1997, but doesn't matter) It is a bit general (originally written for VisualWorks) but it covers most of the important techniques (at least I think so ;)) and you can use almost everything you read 1:1 in squeak. On the other hand, it forces you to have basic Smalltalk experience (not all the basics are covered) Max Melzer Please excuse my bad English :D

Version Control and new VMs
by Fabio Oliveira 05 Nov '06

05 Nov '06

Hi, I started to play recently with Squeak and Smalltalk. My impression is the Squeak and the Seaside Framework are moving targets, very exciting pieces of code, but if I start a project this week, in the next week will be available a new VM, or a new image, a new Seaside version, etc... Very good, because it means a very productive and creative community. But if I have a project, and want to migrate to a new image version? or to a new Seaside version? What is the right/easy way of doing this? Change sets? Maybe my question is how to do version control and manage conflicts? How to migrate to new images? Thanks, Fabio

Building a simple web service
by Chad Nantais 03 Nov '06

03 Nov '06

I want to build a simple web service that lets clients fetch rates (returned in custom XML) by sending a REST request. Very basic stuff. What's the easiest package with which I can create an XML web service? Swazoo? Kom? Thanks.
