The 19th International Smalltalk Joint Conference is being held in Edinburgh, Scotland this year on 20-26 August 2011; with Camp Smalltalk running on 20-21 August and the main conference continuing on 22-26 August.

As usual, it will also play host to the International Workshop on Smalltalk Technologies, a forum to trigger discussion and exchanges ideas around advances or experience in Smalltalk, which will be held on 23 August.

This year will also see the 8th competition for the Innovation Technology Awards for excellent Smalltalk projects.

But, as always, the main attraction will be the chance to meet, discuss and socialise with old and new Smalltalkers from around the world.

There is an open call for papers; registrations are now open; and bookings are being taken for accommodation during the conference (which is being held at the same time as the world famous Edinburgh Festival, so early booking is essential).

To encourage newer Smalltalkers, there is a student volunteer programme, and also the opportunity to apply for one of ten free places by emailing the ESUG board with subject: [ESUG 2011 Free entrance] + your name, and your case for receiving a free place.

You can support the ESUG conference in many different ways:

  • Sponsor the conference. New sponsoring packages are described at http://www.esug.org/supportesug/becomeasponsor/
  • Submit a talk, a software or a paper to one of the events.
  • Attend the conference! The board would like to beat the previous records of attendance (156 participants at Brest, 170 people at Amsterdam, 150 at Barcelona)!

See you all there!

Alain Plaintec has published the call for papers for the International Workshop on Smalltalk Technologies which will be held on 23rd August during the ESUG 2011 conference in Edinburgh. The goal of the workshop is to “create a forum around advances or experience in Smalltalk and to trigger discussions and exchanges of ideas”.

Participants are invited to submit short and not-so short research articles, of two kinds

  • Short position papers describing emerging ideas.
  • Long research papers with deeper description of experiments and of research results.

Contributions can be on a wide range of topics, including meta-programming and meta-modeling, new dialects or languages implemented in Smalltalk and experience reports.

Key dates:

  • Submission: 17th June
  • Feedback: 15th July
  • Workshop: 23rd August

Smalltalks 2010 took place last weekend, meaning that the post-conference reports have started hitting the blogs, and they’re universally enthusiastic about the content, organisation and atmosphere of the event.

Organised by Fundacion Argentina de Smalltalk (FAST), and hosted this year by Universidad Tecnológica Nacional, in Concepción del Uruguay, Smalltalks aims to “strengthen the Argentine and international Smalltalk communities through the exchange of works, experiences and anecdotes connected with this technology or related matters”. This year’s speakers included Gilad Bracha, Eliot Miranda, Lukas Renggli and many many more (see the conference home page for a full listing and descriptions of talks).

German Arduino described it as an “excellent event, with very very good organization—thanks to the hard work of FAST people—and high level technical talks”.

Felipao Banados was attending his first Smalltalk conference, and was also impressed: “I remember talking with classmates and hearing things like ‘Yeah, Smalltalk, nice. But where can you work on that afterwards?’ Well, there ARE a lot of interesting places to do it, and there is a need for smalltalk programmers.”

Andrés Valloud posted some rocking photos of the social event, and reported that the conference even got coverage in the local paper, including a video interview with Hernán Wilkinson.

As James Robertson wrote: “Sounds a lot like ESUG to me – and that’s a good thing.”

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.

This year’s ESUG conference will host the 6th annual Innovation Technology Awards. The top 3 teams with the most innovative software will receive, respectively, €500, €300 and €200 during an awards ceremony at the conference. Developers of any Smalltalk-based software are welcome to compete, and, for the first time, this year entrants are asked to provide a 3-5min video explaining each entry.

There are lots of interesting projects up for the competition, based on Squeak, Pharo, VisualWorks, and Smalltalk/X.  You can find out more about the competition at http://www.esug.org/Conferences/2010/Innovation+Technology+Awards, and of course, you’ll be able to see them for yourself at the conference. See you there!

Luc Fabresse invites all Smalltalkers to submit your Smalltalk based software to the 7th ESUG Innovation Technology Awards. The top 3 teams with the most innovative software will receive, respectively, €500, €300 and €200 during an awards ceremony at the 18th International Smalltalk Joint Conference 2010 in Barcelona, Spain.

No constraints are put on the software except that it should be Smalltalk-based or Smalltalk-related and all flavours of Smalltalk are accepted. Last year’s entries included student projects, one-man labours of love, and full commercial applications.

Don’t forget that early registrations for the conference are only open for another month. You can register at http://registration.esug.org/ (running on Seaside). This server comes with new features: you can now do a group registration and make a single payment; it also allows you to book and pay for reduction tickets (typically for Golden and Platinum sponsors).

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.

Juan’s work on Morphic 3 is supported by ESUG’s Support Your Project programme.
