WavePlace 2

Hi everyone,
We’ve just posted two new videos from the St John Waveplace pilot, which concluded three weeks ago. The first shows mentoring during the pilot. The second shows students presenting their Etoys storybooks.
1) Scenes from the St John pilot (4 minutes)
2) The St John Storybook Awards (8 minutes)
We will be posting the actual storybooks to our website soon so you can see them for yourself.
In other news, the Haiti pilot will resume next week, since things have calmed down in Port-Au-Prince. The kids and teachers are well.
As always, if you’d like to hear more from us, please subscribe to our newsletter or donate money on our website to help with our courseware and pilots.
Take care,
Timothy Falconer

Squeak by Example, 2.0!

12 March, 2008

Squeak By Example

Stéphane Ducasse has just announced that the second edition of Squeak By Example has just been published. It is available for download from the Squeak By Example website, or if you prefer paper to phosphors, you can order a hard copy from print-on-demand publishers lulu.com for only €16.18/$20.10/£11.07.

Licensed under the creative commons by-sa licence, the first edition was a great success, with over 20,000 downloads in less than six months. For the second edition, the authors Oscar Nierstrasz, Stéphane Ducasse, Damien Pollet and Andrew P. Black, have reviewed and revised the contents based on feedback from readers.

At over 300 pages, the book is an excellent introduction to developing in Squeak, and the overall organization and choice of topics makes it a great reference work.

Waveplace XO Day

Great video of the Waveplace XO Laptop Day.

SqueakSVNAt the Hasso-Plattner-Institut (HPI) in Potsdam, all Bachelor students have to participate in a software development project in their final year. Said projects are usually issued by industry collaborators, and hence are “real” development tasks that often yield actual products. The different HPI research groups coach the student project groups.

This year’s Bachelor project of the Software Architecture Group was issued by CollabNet, the company that spawned Subversion. The students are working on SqueakSVN to make SVN version control and tooling available in Squeak.

Coaching in the Software Architecture Group includes training in agile methodologies, with a strong emphasis on Extreme Programming. Of course, this includes heavy testing.

The students were facing the question of how to make the current project status perceivable in a motivating way. Ideally, the status should be immediately visible when entering the project room in the morning, without the need to start up a Squeak image and run all the tests first.

ampel2They came up with a really nice idea: the “test stoplight”, or, rather, “golight” to make it sound more positive. It’s as simple as this. A wooden board, three red, yellow, and green light bulbs, sockets, power supply lines, and an USB-controlled multiway connector make up the hardware part of the golight.

Realizing the software part was also easy. One computer plays the role of a dedicated test server, running a Squeak image. In this image, a process checks out the most recent version of the software from the repository every five minutes, runs all the tests, and switches on the light corresponding to the color of the TestRunner bar. At night, it switches the lights off entirely.

leiste.jpgThe software does not even have to know anything about the protocol used to drive the multiway connector. The connector comes with a set of command-line tools that can be run from Squeak using OSProcess. These are currently limited to the Windows operating system, but since controlling the connector is basically about writing some data to a serial connection, it should not be too hard to come up with solutions for other platforms.

This morning, when I first saw the golight, it was showing green.

Feel free to contact us for detailed building instructions and information related to the software!
