Alan Kay Meeting the Next Generation.  See the talk here: http://www.heidelberg-laureate-forum.org/blog/video/lecture-friday-september-27-alan-kay/


Sad news.  Most of the Smalltalk community knows all about Doug through stories shared by Alan.  Some of you have been lucky enough to have met him.  Much of what we know about computers was invented by some really terrific minds.  Today we lost one of the best.  It is amazing how far technology has progressed in such a short time.  We are lucky to live in a time that still has so many of the great inventors still alive.  It’s an amazing time to be standing the the shoulders of giants.  Alan Kay reminds us that all of the present is not made up of all of the past.  Only part of what was done back then survived and is in use today.  Some of our history is better than our present.  We should all take a moment and remember that past.

I couldn’t help but notice that Doug has three controls.  The Mouse the keyboard and what?  A function menu?  A view selector? Just what is that left hand doing?  I know I’ve tried to explain ctrl-c to people and even today many people have no idea that keyboard shortcuts exist.  Just a thought.



Chris Cunnington reminded the Squeak-dev mailing list that for a while now he’s been creating video tutorials explaining aspects of Squeak. In fact he’s been working at this for so long that he now has over 70 videos available!

The videos give snappy introductions to topics as varied as: using SqueakSource to download Squeak applications; the mysteries of the red, blue, and yellow mouse buttons; how to use morphs; and using Croquet to interact in 3D environments (as seen above).

If you want to learn about Squeak, or to find out more about Squeak applications you’ve never used before, these are a great resource, so head over to Chris’ Smalltalk Medicine Show channel on YouTube. If you know of other great videos for newcomers to Squeak and Smalltalk, please let us know in the comments.

New Screencasts on DrGeoII

20 August, 2008

Hilaire Fernandes has announced that he has created over 50 screencasts illustrating the capabilities of DrGeoII. DrGeoII allows students at primary or secondary level to create and interactively manipulate geometric figures within definable constraints.

It is written using Morphic in Squeak Smalltalk, and can be embedded and mixed with existing Morph elements of the Squeak environment on the OLPC XO to produce some very impressive-looking activities to help students learn about mathematics and physics. The DrGeo wiki has lots of useful advice on how to get the best from the application.

Development of Dr. Geo II was partly sponsored by TOP, the Taiwan Open Source Project, with funding from the Taiwan Ministry of Economy, and by ESUG to promote the Smalltalk language.

Avi Bryant Interview

28 July, 2008

Werner Schuster from InfoQ.com spent some time talking to Avi Bryant at QCon London 2008, and InfoQ have posted a recording of their conversation. In the interview, Avi talks about the Smalltalk web framework Seaside, DabbleDB, using Smalltalk images for persistence instead of an RDBMs, GemStone and more.

The Squeak mailing lists have recently seen a surge of interest in getting videos published to help explain Squeak and Smalltalk to developers coming to the language and environment for the first time.

In response to this Randal L. Schwartz has set up a new Squeak Smalltalk group on vimeo.com to allow Squeakers to easily upload and share their videos.

Videos can be a great way to help people quickly pick up a lot of complex information, which makes this an opportunity for Squeakers old and new to help promote Squeak. If there are any topics that you think would suit a short video, why not try recording one and publishing it? If you’re the developer of a powerful Squeak developer tool, and you’re amazed that no-one seems to use all of its functionality, this would be a great way to expose all of those features in a compelling way.

If you’re a new developer struggling with Squeak, let us know what topics you’d like to see covered in video tutorials. If you’ve got any recommendations for recording and editing software for Windows, Mac or Linux, please leave a comment.
