[Pharo-project] Traits in OB
by Alexandre Bergel Dec. 19, 2008

Dec. 19, 2008

Dear List and David, I truly enjoy your browser (especially the superOB one :-). It would be really useful to know when a trait is selected what are the traits and classes that use it. I could make up something (e.g., textually displaying the list of users below a trait definition)...

[Pharo-project] OB Monticello
by Damien Cassou Dec. 19, 2008

Dec. 19, 2008

Hi, Dale Henrichs has implemented an ob-based version of Monticello. It works very well and contains most of the features of the current mc-browser. It's released under the MIT license. What do we want to do with it? You can download it at http://source.wiresong.ca/ob/OB-Monticello-dkh.68.mcz -- Damien Cassou http://damiencassou.seasidehosting.st

[Pharo-project] Fwd: Multi-core Pharo?
by StÃ©phane Ducasse Dec. 19, 2008

Dec. 19, 2008

Hi I forward you the email Andreas wanted to send to the list. Here it is. Stef From: Andreas Raab <andreas.raab(a)qwaq.com> Date: December 19, 2008 6:41:21 AM CEST To: Igor Stasenko <siguctua(a)gmail.com> Cc: Oscar Nierstrasz <oscar(a)iam.unibe.ch>, stephane ducasse <stephane.ducasse(a)free.fr >, "Klaus D. Witzel" <klaus.witzel(a)cobss.ch>, Alexandre Bergel <alexandre(a)bergel.eu >, Pharo-project(a)lists.gforge.inria.fr, Eliot Miranda <eliot.miranda(a)gmail.com > Subject: Re: [Pharo-project] Multi-core Pharo? Hi Igor - I think I'm missing some context here. I don't know what sore spot Oscar is referring to and which political problems. From my perspective the situation is that we have released Hydra under MIT and that consequently no "political problems" exist (at least on this end). From the technical perspective you are of course right. The issues need to be addressed from various angles simultaneously. Hydra at this point is a proof-of-concept, no less, no more. To make this useful we need to address a variety of problems, including how to actually write programs in such a setup! ;-) This gets forgotten too easily - people assume that things get magically faster but really, Eliot is working on that part. Hydra requires some deep thinking about to structure applications properly so that they actually perform better than before. Of course, having smaller images will help tremendously because it allows more experimentation with smaller footprints. This is an issue that we continue to look at both from the shrinking as well as the construction approach.
