Could we keep Pharo-dev for Pharo-dev?
by stepharo Jan. 16, 2015

Jan. 16, 2015

Hi guys I will start to be picky about the mails to which I reply or even read. We should be more disciplined. Pharo-dev should be about Pharo-dev this is important for our concentration. I really like the other discussions but we should have them in Pharo-users. I think that it makes sense. Stef

Roassal and super large screen
by Alexandre Bergel Jan. 15, 2015

Jan. 15, 2015

Dear all, We have reached a milestone today. We have been able to make Roassal display on a super large screen gently provided by INRIA Chile. If there would be a contest on displaying Roassal-made visualizations on the largest (and most expensive) super-screen ever, then we will be on a good run. >From the technical point of view, we export SVG and use a cluster-friendly SVG renderer. This expands the range of what can be achieved. Cheers, The Object Profile Team -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Making objects persistent
by sergio_101 Jan. 15, 2015

Jan. 15, 2015

I am building a seaside application, and am in the process of building my models and unit tests. I have a few objects that build up my data by creating objects. when i run the data creation methods, everything is fine. immediately afterward, since these objects to belong to anything, they are cleaned up by garbage collection. is there a way to create these objects so that they persist? if this is possible, how would you go about deleting such a tenacious object? thanks!

Stackoverflow, was: [Pharo-dev] Could we keep Pharo-dev for Pharo-dev?

Flagging it just gets clueless moderator replies: "declined - The question really needs to be fleshed out. Including the code for the rectangle morph would help a lot." An earlier one was Command pattern in smalltalk [closed] (you might not be able to see that as it was deleted). Of the 10 most popular smalltalk questions, at least 8 would be closed using current moderation standards. There is not 1 question from last year amongst the 50 most popular questions. In the top 100 there are 2, and the most popular one is about Objective C. The most popular question from last year gets 7 votes. That means there are not enough smalltalkers on SO to be able to reopen questions. The gaming system basically values popularity of answers, not correctness. It reinforces majority choices.

Stackoverflow is not an effective channel. Ignoring it is not smart. Answer questions and point people to the mailing lists. Stephan

[ Book Review ] Lauren Ipsum
by Sven Van Caekenberghe Jan. 15, 2015

Jan. 15, 2015

Every now and then you come across a book that is special. A couple that I remember are 'Structure and Interpretation of Computer Programs' by Harold Abelson and Gerald Jay Sussman for its high level of abstraction over petty details and its breath of subjects, 'The Little Schemer' by Daniel Friedman for its mind blowing Q&A style introduction to recursive thinking or 'The Connection Machine' by Danny Hillis, a doctoral thesis that read like a science fiction novel. Closer to Pharo, 'Smalltalk Best Practice Patters' by Kent Beck surprises by being deceptively simple yet profound and by transcending the language for general object design principles. 'A Mentoring Course on Smalltalk' by Andres Valloud manages to bring across very advanced ideas mostly by discussing the implementation of one or two relatively simple problems. So what about a (children's) book about computer science without any (pseudo) code or math ? And make it fun too, please. 'Lauren Ipsum' by Carlos Bueno and Ytaelena Lopez [ http://www.laurenipsum.org ] does just that. It is a story about a girl that is lost in some magic land and wants to get home. Along the way the fundamental principles of computer science get woven into the story - as if they were the most normal thing in the world (which they are). I was smiling all the time, for all the little jokes and references, although many of those will be lost on those that are not computer nerds. Graph searching, reader writer problems, abstraction, heuristics, networking, communication and so on are all part of the story. Beautiful. I read the e-book version in iBooks on my iPhone without any layout problems. Recommended.
