Writing customized UI's using Morphic

Had a little bit time this evening. Not enough to do anything serious with Smalltalk - but enough to answer a question on the Squeak mailing list by writing a simplified "Handy Simulator". It's only behavior is to switch the screen on and off by using the power button.

It's a nice example of using morphic to build a customized user interface. The package is registered on SqueakSource and can directly be loaded into squeak using the SqueakMap package browser.

Free OmniBase

Looks like the OmniBase Object Database for Smalltalk is now free. The download page includes:

"OmniBase is available for free for commercial and educational purposes. Free version of OmniBase is prohibited to be used in the oil or military industries."

There are versions for several Smalltalk dialects: Squeak, Dolphin, VisualWorks, VisualAge and ST/X.

Bicephale project

Michal announced the first version of his "Bicephale project" which tries to change Seaside to make it handle elegantly the display of static, long-lived objects.

Note that it is early code - but since the package contains no modification to base Seaside classes it should be harmless to install it into your Seaside image.

Interim Pollock Release

Samuel S. Shuster has published an interim version of Pollock to the Cincom Public Repository. Pollock is the new GUI framework for VisualWorks Smalltalk.
Read more in the newsgroup or on his blog.
