Smalltalk allows everything to be accessible and modifiable through a live programming environment. The system's objects can be understood and fixed directly. This contrasts with traditional languages where the programmer must mentally switch between documentation, libraries, and code. Smalltalk also provides a permissive license and community support through mailing lists and projects. While it takes adjustment to its different approach, Smalltalk aims to keep programming intuitive through its interactive, self-documenting nature.

1. Why Smalltalk?I made up the term “object-oriented,” and I can tell you I did not have C++ in mind.– Alan Kay

2. Live environmentcode spread around files e.g. RubyIncludes external and system codehttp://frank.itlab.us/photo_essays/wrapper.php?dec_27_2006_bridge.html

3. Turtles all the way downSystem objects are accessible!Fix it yourselfUnderstand how things workSee how the masters codeWilliam Warby http://www.flickr.com/photos/26782864@N00/2499825928/

4. Simple

5. Everything is right in front of youVS.A Library of C++ Gotcha Books1. One tutorial2. One style guide

6. No mental context switching at the system levelMac OS X Cocoa “Fundamentals”VSLive objects

7. No mental context switching at the language levelC++ LibrariesVSSending Messages to objects

8. DocumentationIdeally part of the system itselfSqueak/Pharo – still a work in progress

9. Why Squeak/Pharo?

11. Really turtles all the way downto the operating system out of the boxcan extend down to the metal e.g. SqueakNOSAn operating system is a collection of things that don't fit into a language. There shouldn't be one.- Dan Ingalls

14. Common MisconceptionsWhy can’t I use [Emacs | VI]?!Where are all my files?!Why doesn’t Squeak/Pharo do X, damn it!?!?
