These are based on my preferences, from most to least preferred 1) GNU Smalltalk includes a refactored version of Swazoo that supports SCGI and is also faster in general. Start from there and backport the changes to Squeak/Pharo. Use Seaside's Grease cross-dialect compatibility layer to get rid of (most of) the Sport dependency. 2) Convert existing cross-platform projects to use Grease. Demonstrate them using two-three dialects (VW, Squeak, GST). Discuss possible extensions to Grease and implement them. Document Grease extension based on the formalism of the ANSI standard. 3) I agreed with the FSF to relicense GNU Smalltalk's file system classes under MIT license. Port them to at least two other dialects (Squeak/Pharo count as one). Think of cool ways to use them. Possibly work out how to integrate them into Grease and make Seaside use them. 4) Build a continuous integration server using Seaside, Iliad or AidaWeb. Build an interface to version control systems (possibly supporting both independent systems such as Monticello or file-based such as svn/CVS/git) that can be used from Smalltalk and integrate it with Smalllint code reports. For a more ambitious project, the server should be able to start a new image, upgrade the package, run SUnit tests there and communicate back the results---the time to upgrade the package should be minimized of course! 5) Work on a cross-dialect foreign function call interface and implement it in at least two dialects. Candidates include Alien and GNU Smalltalk's CObject (using existing implementation has the advantage of having to implement in only _one_ other dialect!). Bonus points for implementing a C parser that would be able to construct bindings. GNU Smalltalk already contains a C preprocessor implementation. Paolo

[Pharo-project] Google Summer Of Code 2010 news!!!

by Mariano Martinez Peck

Hi smalltalkers. I have been asked to be the admin of GSoC 2010. The backup or second admin is Janko MivÅ¡ek. As you may know, Squeak has participated in GSoC 2007, 2008 but failed (not accepted) in 2009. We are not sure if we will succeed this year but we will try to do as much as possible. We think that one of the most important reasons why we failed in 2009 is that Google was looking for bigger communities that Squeak. This is why this year we all go under the ESUG umbrella. We present ESUG as the mentor organization and we cover ALL open-source Smalltalk dialects, not only Squeak. Pharo, Smalltalk/X, GNU Smalltalk, Cuis..they are all invited to participate. Also cross platform projects like Seaside, AidaWeb, Magma, etc are welcome. <forThoseWhoDoesntKnowWhatGSoCIs> It is a Google program that support (money) students to work on different open-source projects. Google doesn't talk or manage directly to the students but trough "Mentoring Organisations". Those organizations have to apply to GSoC. They have to give a lot of information, included a list of ideas/projects. Each project has a description and a mentor. Then the students apply for each project. If the organization gets selected by Google they will tell you how many "slots" they give. Suppose they give 5 but we have 20 projects....then we vote and the most voted projects win. The student has to do the project and the mentor has to help and guide him. The mentor receives 500 USD and the student 4500USD. For more information read: http://code.google.com/soc/ </forThoseWhoDoesntKnowWhatGSoCIs> The most important thing is the deadlines we have. We started late so we are very near to the first deadline which is 12/03/2010 (less than one week). For that deadline we need to submit all the information of the mentor organization (answering several questions) and give the list of ideas/projects and the mentors of that. We have created a webpage (Thanks Janko!!) where we will put all the information. We will make this page public soon (we still need to review a couple of things). But for the moment we would REALLY appreciate if tell us your ideas. To do this, just answer to this email. Then we will collect the information and put in the website. For each idea you need: a short title and a paragraph (for the moment) explaining the idea. After, we need that the people that are willing to be mentors start to apply as mentors...please, consider yourself being mentor. Sometimes it is not that difficult. I mean, don't be shy as sometimes being helpful, being aware of the dates, answering emails, etc is more important than the Smalltalk knoweldege. We can have a lot of ideas, but we need also mentors for that. We even would need a "substitute" for each mentor... Just as an example you can see the ideas of the previous years: 2007: http://wiki.squeak.org/squeak/5936 2008: http://wiki.squeak.org/squeak/6031 2009: http://wiki.squeak.org/squeak/6120 That's all for the moment. Cheers Mariano

I guess then just my initials are everywhere. Anyway, the point is that we fix all the places that need to be fixed. I have the RB rewrite script that does that already, I've posted a list with all the affected methods earlier on (there are about 30). > Personnally, I want the warning.

This preference would be usefull only to load old packages, but risk to be abused to write non conforming code. Personnally, I want the warning. It's so easy to get bitten by ^x/-2...

For the compile changes themselves I wouldn't throw a warning, not even in interactive mode. Also I wouldn't add a setting, that just causes troubles in many years ahead.

[Pharo-project] Pharo help (was About danny help :)

by Torsten Bergmann

Hi Danny, > I am the first to acknowledge that this is your project. No, no - it is not mine or yours. It is "Pharo Help" and it is "our" project - that's why the repo is open and the code is MIT! Didnt you see the ;) behind my statements! >And I am also the first one to admit that my code is not great How do you measure the greatness of code? ;) Dont by shy! You idea and code is a great addition since we can and will definitely use it. Anything I've said is that I want to restructure it to align it with my design ideas (which I was not yet able to fully communicate since I'm in the midst of changing the original design) >being a beginner with Smalltalk in the first place, not being a software >developer secondly Sometimes developers are already too "computer focused" in thinking. So we need people with a different background and fresh ideas. Welcome to Smalltalk! >and playing with software only in my spare time (which will be >certainly much less in the future, because I just got a brand new >daughter). Excellent! I have two daughters myself (2 years and a 7 month baby). >So please see my contributions more as sketches of the functionality that >might be nice to have in a help system, rather than a real implementation As I said - it will definitely in the next version in one way or the other.
