back-to-the-future

More exciting conference news for Smalltalk aficionados: James Foster has announced on his blog that this year’s OOPSLA conference will include several tutorials with a Smalltalk theme including his “Back to the Future: Programming in Smalltalk” in which he will look at the “new” ideas from Smalltalk that are still influencing newer programming languages. He will examine some of these ideas and present a number of tutorial exercises that explore some of Smalltalk’s  fundamentally different approach to language design and object orientation, including the following aspects:

  • All values are objects, even integers, booleans, and characters (no boxing/unboxing);
  • Classes and methods are objects (supporting reflection);
  • The language has only five reserved words;
  • All control flow (looping and conditional branching) is done through message sends;
  • Programming is done by sending messages to existing objects; and
  • The base class library can be modified.

James works on Gemstone’s high performance product family based on Smalltalk, but intends the exercises to be relevant across different versions.

This year’s OOPSLA will be held in Orlando, Florida from 25 to 29 October, and will also be co-located with the Dynamic Languages Symposium, which will doubtless have lots to interest Smalltalkers.

On the other hand, if you’re looking for a European break this year, don’t forget that the 2009 International Smalltalk Conference, organised by ESUG, will be held in Brest, France, from 31 August to 4 September, and also has a great set of sessions lined up.

Despite recent discussions over what killed Smalltalk, there continues to be lots of interest in the language and in Seaside in particular. Anyone based near London will be able to find out more about both topics at a talk dramatically titled “Seaside: The Revenge of Smalltalk“.

This “Geek Night” is going to cover how Smalltalk makes web development different and how Seaside is being put to use in the “Real World”. Participants will learn about real object-orientated programming rather than class-orientated programming.

The two presenters are Lukas Renggli, who will be talking about Squeak and the world of Open Source Smalltalk; and Michel Bany from Cincom who will be discussing how Seaside and Smalltalk has been used in companies like JP Morgan.

The talk is hosted by Thoughtworks‘ London office on Monday 6th July, 2009 from 7:00pm—10:00pm.

Nicolas Chen has posted a very interesting report on the Squeak and Seaside ‘Birds of a Feather’ sessions at this year’s OOPSLA Conference in Nashville, Tennessee. Speakers included Michael Lucas-Smith of Cincom talking  about their WebVelocity development tool for Seaside; Göran Krampe on Blackfoot, his lightweight SCGI-based KomHttpServer replacement for Seaside deployment; Dave Ungar (ex-Sun Labs, now at IBM Research) on his work on multi-core Squeak; and Jecel Assumpcao Jr. on Smalltalk Hardware Design, and his Siliconsqueak project.

As promised, Göran has published videos of the sessions; see his blog for details.

Squeak BOF at OOPSLA 2008

7 October, 2008

OOPSLA, the “original conference devoted to object-oriented programming”, is running this year on 19th-23rd October in Nashville. Göran Krampe wrote to the mailing list to let attendees know that he is organising a Squeak “Birds of a Feather” evening session on Tuesday at 18:00.

Göran has had experience of organising these events in the past, so you can be sure that the logistics have been thought through carefully – he’s even bringing his own projector with him from Sweden, rather than rely on the equipment available at the venue! All the videos of all the presentations will be made available after the session.

If you’re interested in attending this session, please let Göran know by adding your name to the OOPSLA 2008 page on the Squeak wiki (if you’re having trouble editing that page, the words squeak and viewpoints may be of some use to you). The wiki page also has information on some other items that may be of interest to Squeakers.

This year’s winners of the ESUG Innovation Technology Awards were announced at the 16th Joint International Smalltalk Conference in Amsterdam last night. There were a record-breaking 21 entrants, with a great selection of innovative ideas and products. Voting was by all attendees of the conference, and the winners were:

1st prizeDrGeoII, Hilaire Fernandes’ development in Squeak Smalltalk of an application that allows students at primary or secondary level to create and interactively manipulate geometric figures within definable constraints, as featured on the Weekly Squeak recently (pdf description available here).

2nd prizeseaBreeze, an application from Georg Heeg eK which allows Seaside developers to work in an interactive environment to develop web content (pdf description available here).

3rd prize – iSqueak, a project from John M McIntosh, Grit Schuster and Michael Rueger, which allows Squeak to interact with multi-touch input devices such as the iPhone (pdf description available here).

The competition was sponsored by ABN Amro Bank, and the winners get prizes of €500, €300 and €200.

Following the ceremony, Georg Heeg announced that seaBreeze will be dual-licensed, with a free versions available under the MIT licence. The code will be made available once some finishing touches have been applied.

Avi Bryant alerted the Seaside mailing list to some exciting news: Cmsbox is one of the ten winners of this year’s useit.com 10 Best Application UIs of 2008, a competition intended to identify the 10 best-designed application user interfaces each year.

Cmsbox is a powerful and flexible Content Management System (CMS) which allows users to create, edit and arrange content directly on the web site. It was built by Swiss company netstyle.ch using Squeak Smalltalk, Seaside and Scriptaculous.

In describing the award, which is the latest in a string of awards won by CmsboxJakob Neilsen wrote that Cmsbox made it “particularly easy for direct users to create highly usable designs [...] They have demonstrated that just one extra line of controls is all that is required to turn a website into a Web authoring environment. [...] There are no modes to switch between, no edit windows to keep track of; it is immediately clear to users what effect their actions will have on the final layout because they are always working within that final layout”.

Avi Bryant Interview

28 July, 2008

Werner Schuster from InfoQ.com spent some time talking to Avi Bryant at QCon London 2008, and InfoQ have posted a recording of their conversation. In the interview, Avi talks about the Smalltalk web framework Seaside, DabbleDB, using Smalltalk images for persistence instead of an RDBMs, GemStone and more.

MacWorld magazine is running a series of reviews of their favourite free and low-cost applications for the Mac, and one of their picks is Plopp, a painting tool from Impara for easily creating cartoon-like 3D scenes. Although their review doesn’t mention this (did they even know it?), Plopp was developed and runs totally in Squeak!, which of course means that it’s also available on Windows and (for free!) on Linux.

Plopp seems to be getting a lot of attention at the moment, perhaps because you can also use it to create models for use in Second Life, so congratulations to all at Impara for the recognition their work is getting!

Most of the slides from the presentations at this year’s Smalltalk Solutions conference are now on line.

The material available includes Gilad Bracha’s talk on Newspeak, James Foster’s guide to building a Seaside application using GemStone/S, Michael Rueger’s introduction to Sophie, Arden Thomas demonstrating WebVelocity in action, and Randal Schwartz’s double-header keynote: Seaside – Your Next Web Framework and an introduction to persistency solutions for use with Seaside.  

There are also slides from a couple of sessions looking at the reasons for the recent resurgence of interest in Smalltalk: Arden Thomas looks at the features of Smalltalk that other languages lack, and Rob Rothwell explains how Smalltalk helps with the development of healthcare applications.

There are many more slide-packs available, and still more to be added, so please check out the conference page for more information. James Robertson is adding video and audio as it becomes available.

Avi Bryant joined Gemstone’s Bob Walker at RailsConf last week for a presentation (summarised here) describing MagLev, a Ruby VM built on the same technology as Gemstone/S, offering transparent persistence, and so the possibility of massive scalability, to Ruby applications. Despite only being under development for three months, with the initial focus being on scalability rather than speed, MagLev is already able to run Ruby code at speeds comparable or better than established Ruby implementations, with orders of magnitude improvements in some cases.

The presentation caused lots of excitement at the conference, and has sparked lots of heated debate within the Ruby development community with some very different views of MagLev from Charles NutterGiles Bowkett,  Obie Fernandez, and Antonio Cangiano, as well as an article at Slashdot and posts all over Reddit.  Avi has a blog-post addressing some of the discussion, as does Patrick Collison.

For Smalltalkers, one particularly interesting feature of MagLev, from an interview with Bob Walker by InfoQ, is that it retains the ability to execute Smalltalk code as well as Ruby, and should support image-based development.

[Edit: Chad Fowler had access to MagLev well before the presentation, and so offers a more considered assessment of it]
