About

This website hosts selected Squeak projects that have been developed in teaching and research activities at the ​Software Architecture Group, which is led by Prof. Dr. Robert Hirschfeld at the ​Hasso Plattner Insitute (University of Potsdam).

All content is made available under the ​MIT license unless specified differently, e.g., ​Creative Commons.

The source code is hosted on a ​SqueakSource installation at our site. Additionally, ​Metacello configurations are maintained to ensure a simple installation process.

Development Issues

This website is an instance of the ​Trac project management software, which provides for issue/bug tracking via tickets in particular. For each project that is listed we defined a so-called component. This allows for associating tickets with projects, since every ticket is defined for a specific component.

Questions and Comments
In case you have questions about contents provided at this site, we would like to encourage you sending a message to our ​mailing list.

Bugs and Feature Requests
If you encounter a bug, unexpected behavior, of if you have an idea on how to improve the project, please consider creating a new ticket.

How to Contribute
In case you extend the code base or eliminate unwanted behavior, please consider contribuing your change. We recommend two ways:

• create a new ticket and attach your proposed changes (e.g., just a source code snippet) to that ticket
  -OR-
• submit the change directly to our ​inbox via Monticello
  The inbox concept is used for development activities on the Squeak image and is described ​here
