Randal L. Schwartz just announced that he will be giving a 3 hour tour of Seaside at OSCON 2008. We are very proud to have Randal on the Squeak Foundation Board. We are looking forward to more of his “Year of Smalltalk“.

What’s the difference?
The following was posted to the Squeak-Dev Mailing list by Markus Denker. The quote speaks for itself and it does give one pause to consider the implications to our community. It also strikes me as relevant to a lot of other development communities too. Great ideas are still very powerful and inspiring, but the idea alone is still seen as only half the process. We all know that there is a lot of very interesting problems that arise while we transform our ideas into working code. We also know that it is much easier to build onto a working system, or take what we learned from the process of building a working system to the next generation. While the idea itself can be seen as a great accomplishment, the realization of the idea by itself confers even greater benefits to the community. What projects have you left undone? What’s the difference?
“One of the sad memories of my life is a visit to the celebrated mathematician and inventor, Mr Babbage. He was far advanced in age, but his mind was still as vigorous as ever. He took me through his work-rooms. In the first room I saw parts of the original Calculating Machine, which had been shown in an incomplete state many years before and had even been put to some use. I asked him about its present form.
‘I have not finished it because in working at it I came on the idea of my Analytical Machine, which would do all that it was capable of doing and much more. Indeed, the idea was so much simpler that it would have taken more work to complete the Calculating Machine than to design and construct the other in its entirety, so I turned my attention to the Analytical Machine.’”“After a few minutes’ talk, we went into the next work-room, where he showed and explained to me the working of the elements of the Analytical Machine. I asked if I could see it. ‘I have never completed it,’ he said, ‘because I hit upon an idea of doing the same thing by a different and far more effective method, and this rendered it useless to proceed on the old lines.’ Then we went into the third room. There lay scattered bits of mechanism, but I saw no trace of any working machine. Very cautiously I approached the subject, and received the dreaded answer, ‘It is not constructed yet, but I am working on it, and it will take less time to construct it altogether than it would have token to complete the Analytical Machine from the stage in which I left it.’ I took leave of the old man with a heavy heart.”

Dan Ingalls demos Lively at Google
Dan Ingalls gave an interesting Tech Talk on the Lively kernel (best viewed in Safari 3 apparently) at Google a few weeks ago – what better way to (re)introduce our new board member?

Squeak by Example, 2.0!
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.

Hashing in Smalltalk
Andrés Valloud has just published “Hashing in Smalltalk: Theory and Practice” on Lulu. He describes the book as providing “a strong foundation for hashing, hash functions, and their application in the context of software development. The first part develops hashing and hash functions from first principles. The behavior characteristics required of hash functions are examined in detail. A thorough description of how hash functions are constructed follows, complete with a rich survey of existing hash functions. But often times existing hash functions are inappropriate for the task at hand. To address this problem, the second part shows how to build novel hash functions that are both efficient and of very high quality for many of the types of data that occur in practice.”The book compares algorithms and implementations of hashing across the main Smalltalks (Squeak, Dolphin, Visual Works and VisualAge), as well as other languages including C, C++, C#, Java, OCaml and ML. It’s available for $40/€32.20/£22.04 .
Andrés has also posted a great illustration of the dangers of the use of inappropriate hashing functions.

16th International Smalltalk Joint Conference – Call for ContributionsAugust 25-29, 2008 – Amsterdam, the Netherlands
http://www.esug.org/conferences/2008/
———————————————————————-For the past 16 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.
As every year, this year’s edition of the largest European Smalltalk event will include the regular Smalltalk developers conference with renowned invited speakers, a Smalltalk camp that proves fruitful for interactions and discussions. Besides, this year will be held the 4th edition of the Innovation Technology Awards where prizes will be awarded to authors of best pieces of Smalltalk-related projects.
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. See below.
* Attend the conference. We’d like to beat the previous record of attendance (116 people at Köthen, Germany in 2004)!
* Students can get free registration and hosting if they enroll into the the Student Volunteers program. See below.The conference features the following events:
* Camp Smalltalk – There will be a Smalltalk camp the 23-24th of august
* Developers Forum
* Technology ForumDevelopers Forum : International Smalltalk Developers Conference
——————
This year we are looking for YOUR experience on using Smalltalk. The list of topics includes, but is not limited to the following:* XP practices
* Development tools
* Experience reports
* Model driven development
* Web development
* Team management
* Meta-Modeling
* Security
* New libraries & frameworks
* Educational material
* Embedded systems and robotics
* SOA and Web services
* Interaction with other programming languagesSubmissions due on 1st June 2008
Notification of acceptance on 15 of June 2008 More information at http://www.esug.org/conferences/2008How to sumbit?

We are proud to announce the 4th Innovation Technology Awards. The top
3 teams with the most innovative software will receive, respectively, 500 Euros, 300 Euros and 200 Euros during an awards ceremony at the conference. Developers of any Smalltalk-based software are welcome to compete.
