Juan Vuletich has been working for some time on Morphic 3, a research and development project aimed at building the next standard in 2D user interfaces. One of his aims is to do mathematically proved alias-free rendering. In order to achieve these objectives, he has been experimenting with several techniques and design features, some which are new and others are not, but have never been consistently applied to a 2D GUI.
Juan’s contention is that, although the theory behind sampling is about 80 years old, existing graphics software completely ignore the theory and that his quest for higher quality results has resulted in the idea of applying the Sampling Theory which allows for mathematically proved alias free rendering. He informed the squeak-dev mailing list of his latest post which makes the startling claim that “I developed new drawing algorithms that give better results than those in Cairo, AGG, etc.” and he has created some examples showing some of the problems with existing algorithms, and how his approach improves these issues.
Juan is preparing the algorithms for release, which will involve him publishing it in a journal or as a Ph.D. thesis, and securing it for free use by either putting the code in the public domain or releasing it under the MIT licence.

Following Google’s decision to focus on fewer organisations last year, ESUG co-ordinated a joint application for projects across all Smalltalk dialects this year, and were so successful in this venture that they got approval for 6 projects. You can find out more about the selected projects at the projects page.
For the last two weeks or so, students have been talking and discussing with their mentors, reading and investigating about the projects, and perhaps getting an early start on their development work. This was in line with the GSoC deadlines that you can read at the ESUG GSoC site and at the GSoC blog.
The organisers have told students to ask in case of problems or questions to their mentors but also to the community through the mailing list, so be prepared to help out with questions and issues that the students may have.
Mariano says “Good luck to all students and enjoy this wonderful opportunity you have. Now we are in the best part of the program!”

Rita Freudenberg has announced that “The official Squeakfest website is now live and ready for you to propose a presentation, workshop, or panel.”
Squeakfest is an annual conference where developers and users of the Etoys media-rich authoring and experimentation environment (based on Squeak) get together to share ideas, experiences, and their enthusiasms with colleagues from around the world.
This year’s conference will be held at University of North Carolina in Wilmington, North Carolina, in the USA from 26th—28th July, and the theme for will be “Etoys in the STEM classroom.”
The team are keen to hear from individuals and groups with experience teaching with Etoys, as well as non-classroom Etoys use, particularly as it relates to OLPC pilots or homeschooling. More information will be added to the website as it becomes available, but the organisers ask presenters to get presentation information to them by completing and submitting the online form no later than 11th June, 2010.
To get a flavour of what to expect at the conference, have a look at our report from last year’s Squeakfest.

The Workshop on Self-sustaining Systems (S3) is a forum for discussion of topics relating to computer systems and languages that are able to bootstrap, implement, modify, and maintain themselves. One property of these systems is that their implementation is based on small but powerful abstractions; examples include (amongst others) Squeak/Smalltalk, COLA, Klein/Self, PyPy/Python, Rubinius/Ruby, and Lisp. Such systems are the engines of their own replacement, giving researchers and developers great power to experiment with, and explore future directions from within, their own small language kernels.
S3 will take place September 27-28, 2010 at The University of Tokyo, Japan. It is an exciting opportunity for researchers and practitioners interested in self-sustaining systems to meet and share their knowledge, experience, and ideas for future research and development.
See the conference website for details and deadlines.

For the past 18 years, the European Smalltalk User Group (ESUG) has organised the International Smalltalk Conference, a lively forum on cutting edge software technologies that attract people from both academia and industry for a whole week. The attendees are both engineers using Smalltalk in business and students and teachers using Smalltalk both for research and didactic purposes.
This year’s conference will be held at Citilab-Cornellà in Cornellà, Barcelona, on 13th—17th September. As in previous years, this year’s edition of the largest European Smalltalk event will include the regular Smalltalk developers conference with renowned invited speakers, and a Smalltalk camp that proves fruitful for interactions and discussions.
This year will also see:
- the 6th annual Innovation Technology Awards where prizes will be awarded to authors of best pieces of Smalltalk-related projects
- an international workshop on Smalltalk and dynamic languages
- for the first time there will be a business day on Thursday 16th September 2010 with a focus on “Agile Development Processes and Smalltalk”
ESUG is sponsoring 10 free entrance tickets.

Hernan Wilkinson wrote to the squeak -dev mailing list that the Smalltalks 2009 presentations are available now at the Smalltalks Conference site under the “Talks” tab. Given that the speakers included such well-known figures as Dan Ingalls, Stephane Ducasse, Alex Warth, Tim Mackinnon, James Foster and Travis Griggs, there should be some fascinating viewing to be had.
Hernan added: “You can watch also the video used during the presentation that summarizes the previous two years of the conference, it is a very nice video. It is at http://www.youtube.com/watch?v=ekRhvg7W6AQ“.
There are also links to other videos and pictures from the conference home page.

All the participants should now have safely returned home after a hugely successful ESUG conference. Participants from around the world (including an Argentinian football team) shrugged off the economic climate to spend a week in Brest and share their experiences and aspirations with fellow Smalltalkers.
- Presentations from a range of speakers from industry and research backgrounds, including Cloudfork, DeltaStreams, WebVelocity.
- Tutorials for Seaside, Aida, SqueakNOS, and many, many, more.
- The Innovation Technology Awards, awarded to Retrobjects which is a great C64 emulator, PhidgetLab which uses eToys to interact with real world objects, SqueakNOS: a lightning-fast bootable Squeak image, and Glamour which is a flexible engine for scripting Smalltalk browsers.
- Updates on various Smalltalk platforms: VisualWorks, VA Smalltalk, Object Studio, Gemstone and Pharo.
- And lots of great opportunities to network and socialise, including the inaugural ESUG Blind Date!
Comments on the web have been very positive too:
- “ESUG was a blast, totally.”
- “Definitely the best Smalltalk conference I’ve ever been to.”
- “a great conference”
- “a pleasure to attend every year”
- “fascinating, inspiring and enjoyable”
- “it’s been intense”
With reviews like that, next year’s conference in Barcelona is bound to be a sell-out, so remember to book early!
