Etoys 4.1 now available

30 September, 2010

Bert Freudenberg announced on the squeak-dev mailing list that Etoys 4.1 is now available. Etoys is a media-rich authoring environment and visual programming system with a simple, powerful scripted object model, ideal for teaching children powerful ideas in compelling ways. Based on Squeak, Etoys is available for free, with an open-source licence. You can run it on Mac OS X, Windows, and Linux (using the Etoys To Go version), or even use a plugin to run it directly in your browser. Etoys is also available on the XO OLPC laptop.

This release includes new features such as DrGeo for exploring geometry, speech bubbles for objects, new tiles and Quick Guides in a number of languages. It also includes a large number of bug-fixes and cleanups. A number of new projects have been created to showcase the new features. Some of the new features were developed as part of Smalltalk’s participation in this year’s Google Summer of Code, which was co-ordinated by ESUG.

You can find out more about Etoys 4.1 by reading the release notes, or by downloading the new version.

This year’s ESUG International Smalltalk Conference ended last Friday, though some attendees are still travelling homewards,  slowly recovering from jet lag, or waiting for lost baggage. Nevertheless, for most of us it’s an appropriate time to look back on the conference.

The conference had a great buzz about it this year. As usual Camp Smalltalk gave early arrivals the chance to get their hands dirty and start hacking on code. Among other activities, Seaside 3.0 was finalised and announced.

A packed official schedule kicked off with a great presentation (mp4) of a gorgeous web-based event planning tool based on Seaside. Following presentations covered topics as diverse as the challenges of development in commercial environments, using native widgets from Squeak on the iPhone, next steps for source management systems, a live workshop introduction to Wolf Pack Programming, controlling robots, a panel discussion of the complex issues of licencing and warranties, vendor roadmaps and much, much more. You can see the conference programme for more information.

There were two events which really lifted the energy levels of the whole conference. The “Show Us Your Projects” session gave each speaker a strict ten minutes to present their pet project. These talks were crammed with too many great ideas and implementations to list – you really must keep an eye out for the video of the session. The Innovation Technology Awards had 15 entrants this year, each of whom was asked to provide a video and present their projects for voting. All the entries were very impressive, but the winners (announced during the social event at the Museo de la Ciencia) were Physical Etoys from the Universidad Abierta Interamericana team, Eliot Miranda’s Cog VM, and Mars (native widgets on OS X) by Esteban Lorenzano.

Some other impressions of the conference can be found at the following sites (please add a comment below if you know of any other interesting posts about the conference):

The conference was hosted by CitiLab Cornellà, who did a great job of making us feel welcome. All the sessions were live-streamed by CitiLab, and videos are being uploaded and hosted by Cincom. On-the-day support was provided by the student volunteers, who were easily identifiable by their stylish red caps!

Thanks to everyone involved in the sponsoring, hosting and organising of the conference, and here’s looking forward to next year’s conference which is to be held in the UK.

Seaside 3.0 released

12 September, 2010

Following some last minute work at this year’s second Camp Smalltalk event, the Seaside developers are pleased to announce the release of Seaside 3.0 on the eve of the ESUG 2010 Conference in Barcelona.

Seaside has undergone a total overhaul, with many classes having been refactored to reduce complexity, decrease coupling, and improve flexibility. The packages in Seaside are now cleanly defined with clear relationships and interdependencies, allowing you to load only those pieces you require. There are improvements in testing, in portability and in performance, as well as much better tools for developers including the Seaside Control Panel for Pharo and Squeak, and the web-based administration interface.

For more information, see the Seaside 3.0 release announcement, or the following links:

And this time we mean it…

9 September, 2010

In an unexpected statement today, Apple have again changed their stance on the use of third-party development tools. In particular, they say that “we are relaxing all restrictions on the development tools used to create iOS apps, as long as the resulting apps do not download any code. This should give developers the flexibility they want, while preserving the security we need”. Daring Fireball has a nice summary of the key changes to the terms and conditions.

This puts us all back to where we were last year, with Squeak again being a realistic choice of development environments for use on the iPod Touch, iPhone, and of course the iPad. John MacIntosh’s port of the Squeak Virtual Machine to iOS, and Bert Freudenberg’s work on multi-touch support will prove very useful resources in getting keen developers up and running quickly. Unfortunately, Apple explicitly rule out any applications that can download additional code after purchase, meaning that Scratch on iOS is probably still out of bounds.

There’s already lots of speculation about what’s driven this change of heart, based on the timing of this announcement (just after the big Apple event last week), its low profile release, and its terseness (reminiscent of Steve Jobs’ rather direct written communications), but whatever the cause, Squeak developers have cause to celebrate!
