ESUG SummerTalk - Fuel, binary object serializer

by Martin Dias

Hi folks. I am really happy to announce that ESUG is sponsoring me for Fuel development through the ESUG SummerTalk. I am Martin Dias, a student at Buenos Aires, Argentina. The idea behind this SummerTalk is to implement Fuel, a binary, fast and general-purpose object graph serializer in Pharo<http://www.pharo-project.org/>. It is based on VisualWorks' Parcels ideas. Actually, the project has already started since several months. Tristan Bourgois and I started with the project while doing an internship with RMoD, INRIA <http://rmod.lille.inria.fr/web/pier>. Since a couple of months, Mariano Martinez Peck <http://marianopeck.wordpress.com/> joined the team, and now he is the official mentor in the SummerTalk. ESUG website for SummertTalk: http://www.esug.org/wiki/pier/Promotion/SummerTalk/SummerTalk2011 The website with all the necessary information is here: http://rmod.lille.inria.fr/web/pier/software/Fuel It even includes slides explaining the algorithm. In addition, a paper is in progress. For the moment, Fuel already provides the following features: - Fast pickle format. It is much faster to materialize than to serialize. - Correctly support class reshape (when the class of serialized objects has changed). - Serialize ANY kind of object. For the moment there is no object to our knowledge that we cannot serialize and materialize. - Be able to completely serialize classes and traits (not just a global name). - Support cycles and avoid duplicates in the graph. - Integration to Moose <http://www.moosetechnology.org/> with an extension to export and import their models. - Detection of globals: for example if you serialize Transcript, it is not duplicated and instead managed as a global reference. - Solve common problems like Set rehash. - Buffered writing: we use a buffered write stream for the serialization part (thanks Sven!). - No need of special support from the VM. - Try to have a good object oriented design. - Well tested (about 120 tests, for the moment). - Large set of benchmarks (even benchmarks for Moose extension). And of course, there are a lot features for the future. You can see some of them in the website and some in the issue tracker: http://code.google.com/p/fuel/issues/list We really appreciate all kind of feedback and comments. If you want to try it, check in the website how to do it. It is extremely easy. Once again, I want to thank a lot to ESUG for sponsoring the project. I plan to create a "news" section in the website with some RSS. I will keep you informed. Best regards, Martin

[[ UK Smalltalk User Group ]] UK Smalltalk User Group Meeting - Monday, May 23rd

by gcorriga

The next meeting of the UK Smalltalk User Group will be on Monday, May 23rd. Tim Mackinnon has recently started looking at JTalk - and how it translates Smalltalk to JavaScript as well as providing the familiar Smalltalk browsers in your web page. It's still a new project, but how does this approach compare to staying native? Come and join us for some interesting smalltalk on this topic. In addition to this, Niall Ross will briefly update us on the upcoming ESUG conference 2011, in Edimburgh. Don't forget that the early registration is now open! We'll meet in our usual venue - the Counting House, close to Bank Station, from 18:30 onwards. -- Posted By gcorriga to [ UK Smalltalk User Group ] on 5/21/2011 10:06:00 AM

Postdoc position in software engineering at University of Chile in cooperation with INRIA

by Alexandre Bergel

Hi! Some of you may be interesting in the following call: -=-=-=-=-=-=-=-=-=-=-=-= Postdoc position in software engineering at University of Chile in cooperation with INRIA A post-doctoral research position is available with the Pleiad Lab (University of Chile) and the RMoD Group (INRIA Lille Nord Europe). The position is scheduled to start in September 2011, but earlier dates are possible. The position is targeted for research on software maintenance and software visualization. Validation of research hypotheses will be carried out using the Pharo programming language. Experience with it, or any other Smalltalk dialect, is a plus (but not necessary). The postdoctoral researcher will be expected to develop independent research initiatives within the scope of the position, design and contribute to the research experiments conducted by Pleiad and RMoD. There is no teaching duty associated with this position. Both Pleiad and RMoD offer a creative, productive and multicultural staff and students, with many collaboration opportunities. Pleiad and RMoD have an extensive expertise and an advanced infrastructure related to software analysis, data mining, testing, meta-modeling and language semantics. The position is funded by INRIA for a period of 12 or 18 months. In order to foster the collaboration between France and Chili, the candidate will have to share his time between Lille, France and Santiago, Chile. The candidate must hold a PhD in computer science. Contact Persons: Alexandre Bergel and Stéphane Ducasse http://pleiad.dcc.uchile.cl http://rmod.lille.inria.fr http://www.pharo-project.org http://www.moosetechnology.org -=-=-=-=-=-=-=-=-=-=-=-= See you in August!

ESUG 2011 registration is live !

by Niall Ross

The title says it all. £315 buys you the all-included early-bird registration: all 5 conference days, 2 Camp Smalltalk days and the full social event. The link at the top of website main page http://www.esug.org/Conferences/2011 takes you to the registration app link (and the registration FAQ if needed - if anything is not made clear in app or FAQ, by all means let me know). Accommodation =========== The registration list and the conference accommodation room lists are separate, because those who live in Edinburgh, and a few others, will register but not need a room, while others will want to stay on for the festival. (However it makes sense for you to use the same email and password when you sign into both lists: the same email speeds our checking that everyone registered has somewhere to stay, and the same password is one less thing for you to remember.) Room reservations are confirmed if you - are registered, or reserve then register - enter specific arrival and departure dates in the room list (or, for those who are leaving later than the conference, if you specified a definite date in the text box). If you do not give specific dates for arrival and departure, your room reservation remains provisional after you register until you update your room-list entry. (If you don't do that reasonably soon after registering, expect a nagging email. :-) ) FYI, the website accommodation page (and some others) have been rewritten to have more pictures and info. See you in Edinburgh Niall Ross ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
