It has commercial relevance and a lot of inspiration from St; in fact, it's a lot like coding in Smalltalk but, like any language without a live environment, your image crashes after every doIt.

Looking for a language/environment for Analysis of Algorithms course

by Dave Mason

Hi, I'm teaching a 3rd year course in Advanced Algorithms, using Dasgupta, Papadimitriou & Vazirani in January. I have decided that rather than assignments, I'm going to have weekly marked labs. Some of those will be paper exercises, but I would like to have a simple language for them to express their algorithms, where the performance analysis would be particularly clear, and it would be a huge bonus if we could bolt an algorithm visualizer/animator on the side. I'd probably use smalltalk if I had my druthers (just because it's so malleable), but I'm guessing that wouldn't be super popular with the students (as they only had a bit of Smalltalk 3 semesters earlier as part of an OO course, and Java is probably the language they know best). If I had more time, I might build a parser for a language that compiled to the SqueakVM, but I don't. Any suggestions? Moose? any other Smalltalkers projects that might be relevant? Thanks, and I'll post a summary if there's any interest+response. ../Dave

www.smalltalk.org

by Jean Marshall and Andy Berry

Hi! I hope you're all OK and having lots of fun! I was in the library the other day, got bored and sat down with one of their computers. 'What do I do now?', I asked myself and decided, quite quickly, to do a Google on Smalltalk. The first site was www.smalltalk.org and I noticed that it talked about the 2010 ESUG conference but had nothing more up-to-date. Could someone send them a message with some more recent stuff? Hope you all have a very Merry Christmas and an extremely Happy New Year! Regards, Andy

STIC conference deadlines reminder

by Alan Knight

The Smalltalk Industry Conference 2012 is coming up March 19-21, and submission deadlines are coming up soon. This year there are two parts to the conference, so there could be some confusion. -*Smalltalk Industry Conference*: This is the traditional Smalltalk Solutions program. To submit, you just need summary information for the talk. The presentations are, at least sometimes, recorded, but there aren't published papers. The deadline for those submissions is VERY SOON -_December 15th_. Call for participation ishere <http://www.stic.st/2011/10/smalltalk-solutions-is-now-called-smalltalk-indu…>. -*Smalltalk Directions*: This is the academic part of the conference, new this year. It accepts academic papers, which will be refereed and a selection of which will be submitted to the Journal of Object Technology. The deadline for those submissions is_January 6th, 2012_. The call for participation ishere <http://www.stic.st/2011/11/smalltalk-directions-call-for-participation/>.

Call for Participation in the Smalltalk Devroom at FOSDEM 2012.

by Stephan Eggermont

Call for Participation in the Smalltalk Devroom at FOSDEM 2012. "A devroom for the Pharo, Squeak, GST, Etoilé, Seaside, Moose Smalltalk projects. Smalltalk environments offer a very high development productivity, unmatched by their successors. Come do some pair programming with us and experience the advantages of a real OO environment." The meetup will take place Sunday, February 5, 2012, from 9AM until 5PM, room AW1.126. This room has 72 seats, a VGA video projector and wireless internet. More information will be available later. Proposals on content and format are welcome. People interested in running a session should announce that on the smalltalk-devroom mailing list, with the following information: - Their name - The project they are associated with - A short bio, to be put on the website along with their speaker name - (optionally) a picture of themselves - The title of their session (which will go on the website and in the booklet) - A abstract describing the session in further detail. - The desired length of the session. - The desired time slot in which they want to hold the session. Suggested values for the duration are 55min, 25min, 6m40 (Pecha Kucha). The desired time slot is meant to help you prevent conflicts with other dev rooms in which you might have a talk or your travel arrangements. The deadline for submissions is December 31, 23:00 GMT+1. Discussion takes place on the smalltalk-devroom(a)lists.fosdem.org mailing list. Please subscribe if you are interested: https://lists.fosdem.org/listinfo/smalltalk-devroom The local VUB/ULB Smalltalkers have been asked to organize a sprint/BSUG meeting on Saturday Februari 4.

Hi guys I encourage you to send article to Smalltalk Directions Stef 19th–21st March 2012, Biloxi, Mississippi Smalltalk Directions is a refereed symposium that will be co-located with the Smalltalk Industry Conference (STIC) in March 2012. The Smalltalk Directions Symposium will run in parallel with STIC, offering a parallel track of presentations of refereed academic work that will be open to all attendees of STIC. We solicit research papers concerned with the future of the Smalltalk language, forward-looking applications of Smalltalk and Smalltalk-inspired languages, and the core technologies supporting such languages, including but not limited to: 1. Libraries & Frameworks 2. Language extensions and contractions 3. Implementation technologies, such as Virtual machines, compilers, instruction sets, garbage collection 4. Object persistence 5. Distributed objects 6. Program development tools and environments 7. Using Smalltalk to educate future object-oriented programmers 8. Design Patterns in and for Smalltalk 9. Modelling 10. Meta-programming 11. Domain-specific languages implemented in Smalltalk 12. Smalltalk on the web Both submissions and final papers must be prepared using the ACM SIGPLAN 10 point format. Templates for Word and LaTeX are available at http://www.acm.org/sigs/sigplan/authorInformation.htm; this site also contains links to useful information on how to write effective submissions. We are working to have accepted papers appear in the ACM Digital library. A special issue of the Journal of Object Technology will be published in conjunction with the symposium. The authors of selected papers will be invited to submit an extended version of their Smalltalk Directions submission to this special issue, which will then conduct its own reviewing precess. Papers must be submitted electronically using EasyChair (https://www.easychair.org/conferences/?conf=smalltalkdirections2) Important Dates Paper submission deadline 6th January 2012 Author notification 4th February 2012 Final version deadline 24th February 2012 Symposium 19th– 21st March 2012 Organizing Committee Andrew P Black Portland State University, USA black(a)cs.pdx.edu Ralph Johnson University of Illinois, Urbana-Champaign, USA rjohnson(a)illinois.edu Roger Whitney San Diego State University whitney(a)cs.sdsu.edu David West New Mexico Highlands University dmwest(a)nmhu.edu

A first check is therefore done by the developer who is merging his changes in the trunk. This change in the trunk is afterwards verified with the questions above. This means that, at that time, problems related to parallel changes are practically non-existant (i.e. the developer who integrates needs to deal with those directly). Daily coordination amongst developers also reduces the possibility on conflicting parallel changes. Such a single branch development is feasible for us because we work with a single software version and excluding changes from the trunk is a very uncommon decision (bad changes need to be corrected appropriately instead of simply left out). > > best regards, > Johan > > On 27 Nov 2011, at 20:45, Tudor Girba wrote: > >> Hi, >> >> Besides the questions you asked, I would be interested in how changes are grouped together.
