That's something Squeak will have to work on. I even wrote 40 pages to describe that we will get a minimal image with no compiler, we have tanker and candle light that are starting to work and we dreamed about it with pavel back in 2005. But this is your time and energy. :) Just be ready for competition because we are going there for real. There are so many exciting paths (type inferences, real modules, git back end) that I do not understand why you just redo what we did.

Re: [Pharo-dev] Corrupt BlockClosure

by Max Leske

I played around with reverting the method and serializing but that doesn't change anything (the existing BlockClosure is obviously not modified). Then I thought that maybe the method was changed during a running DFSession but still couldn't reproduce. @Roberto Can you tell us anything about what you did befor / during / after running your session?

Vote for GSOC project: SciSmalltalk

by Serge Stinckwich

Dear all, I have submitted a gsoc project called SciSmalltalk. This is a new Smalltalk project, similar to existing scientific libraries like NumPy, SciPy for Python or SciRuby for Ruby. SciSmalltalk already provide basic functionalities under MIT licence: complex and quaternions extensions, random number generator, fuzzy algorithms, LAPACK linear algebra package, Didier Besset's numerical methods, ... We want to extend SciSmalltalk to solve ODE (Ordinary Differential Equations). I you are a gsoc mentors, I would like to encourage you to give your vote to this project ! I believe this really important if we want to offer new alternatives for people who want to made science, mathematics, statistics and big data with Smalltalk ! The student for this project is very capable, because she is a mathematician student. We definitively need to support girls involvement in Smalltalk development and computer science ! Thank you. Regards, -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

Re: [Pharo-dev] DND refactoring

by Carla F. Griggio

Actually when I use Pharo I use the mouse quite a lot. Maybe because I never got used to its shortcuts or I'm lazy to memorize them (at some point I had to re-learn them, and I was too lazy to do it :P). I have the feeling that I'm not the only one using a lot the mouse, and interactions like these would get along very well with that common user behaviour. We actually already have some drag & drop refactorings, like moving a method from one class to another one :) Great article, thanks Stephan! On Thu, May 23, 2013 at 10:50 PM, Sean P.

Re: [Pharo-dev] Corrupt BlockClosure

by Camille Teruel

Hi, This is indeed strange, the BlockClosure has an incorrect startpc (31 instead of 43). You can fix it with: theBlock instVar: 2 put: 43. The wrong startpc corresponds to the beginning of the block in the previous version of the method (DFSession>>#numberOfMethodCalls), but I don't know why. I don't know fuel enough but could it be because the method of the block changed between serialization and materialization?
