Thanks Damien! I am currently travelling. I will have a closer look at your fix next week. Thanks for your work!

Looking for PhD students
by Michele Lanza Aug. 28, 2014

Aug. 28, 2014

Dear all, this is an informal call for PhD students. Iâm Michele Lanza, head of the REVEAL research group from the University of Lugano in Switzerland, active in Smalltalk since many years (16 to be precise). The group, which you might know from tools like CodeCity, SpyWare, Softwarenaut, SPO, etc. and its involvement in Moose and Pharo in general, currently features 4 PhD students and 1 postdoc. 3 PhD students program with and in Pharo, namely Yuriy Tymchuk, Roberto Minelli, and Tommaso dal Sasso, who recently attended ESUG. Iâm looking for one or maybe even two PhD students. Topics with me are normally open and agreed upon by both sides, as long as itâs fun and relevant. I have some funky open topics. The only requirements are an open mind, good OO skills, the willingness to learn and to work hard. Drop me a line if youâre interested or know anyone whoâs interested. Thanks Michele BTW, I could say things about the nice climate in Lugano, the relatively good salary conditions, the generous available funding for traveling and hardware, etc. but if you come only for that you better stay away from me :-)

athens wrapper for (Form-)Canvas
by Nicolai Hess Aug. 28, 2014

Aug. 28, 2014

I tried an alternative approach for rendering Morphs on athens without implementing drawOnAthensCanvas for every morph: 13866 <https://pharo.fogbugz.com/default.asp?13866> AthensFormCanvasWrapper still struggling with the text rendering. Yet I am not sure what is the better approach. Nicolai

Pharo Development Robustness (was: Why Bloc?)
by Sean P. DeNigris Aug. 27, 2014

Aug. 27, 2014

The most important items on our IU Experience agenda - Tx and Bloc - are totally reliant on two (brilliant, talented...) programmers while the rest of the community hopes and waits. In no way to I lack appreciation for Alain and Igor's efforts, but this does not seem like a robust or efficient use of our manpower... So, I guess what I'm really asking for both projects is - how can we help? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Pharo-Development-Robustness-was-Why-Bloc-tp4774980.h… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
