[Pharo-project] GSoC idea: Brainstorming portal for better community decision process
by Janko MivÅ¡ek March 11, 2010

March 11, 2010

Dear Smalltalkers, Becasue we have quite some problems in a community with seeking a consensus on important questions, from organization ones and on, I came to idea to build a tool for help. And a GSoC project can be an ideal opportunity to build such a tool. What do you think? Here is a description: Brainstorming portal for better community decision process ========================================================== Create a web portal for brainstorming sessions/meetings to get ideas and answers to important questions in Smalltalk community. Portal should allow on-line to: 1. brainstorm the ideas 2. vote to get-out the best ideas 3. seek consensus 4. analyze - report On-line session/meeting should look like a Skype session together with a brainstorming portal, from collecting ideas to a final decision proposal. Example of such session can be a Squeak Oversight Board meeting or planning session for a new Smalltalk project. Or some broader session in the community, like on a question how to organize better. Some important concepts: * anonymity of idea proposers * associations: proposers see the ideas of anonymous others to facilitate an association for proposing an even better idea * seeking consensus to avoid 51/49% decisions but to come closer to 100% agreement on important ideas. Technical details * a web application for gathering brainstormed ideas in real-time (using Ajax and Comet technology). * voting system with appropriate algorithms * analytics with on-line graphs and reports on paper/PDF * installation on a publicly available hosting server Benefits to the Student * getting insight into group dynamics of Smalltalk community and in general * gaining knowledge of modern web technologies in Smalltalk and in general Benefits to the Community Better community decision process by getting the best ideas from the members while on the other side avoiding stalemates so frequent in Smalltalk community those days Best regards Janko -- Janko MivÅ¡ek AIDA/Web Smalltalk Web Application Server http://www.aidaweb.si

[Pharo-project] Pharo Win32 VM update (3.11.8)
by Torsten Bergmann March 11, 2010

March 11, 2010

Based on the Squeak Win32 VM update from Andreas (see [1]) I created an update for the Pharo Win32 VM which you can either download directly [2] or from the pharo download page [3]. This VM also includes the fix from Juan so the white rectangles should never show up again when dragging a browser in Pharo 1.1. The full pharo installer for Pharo 1.0 (setup_pharo1.0-10508-rc2dev10.01.2.exe) does not yet contain the 3.11.8 VM since we dont have a new image - so no reason to regenerate the setup. As soon as this is the case I will include it there or any newer VM release. Bye T.

[Pharo-project] How I build squeak-vm with FT2Plugin on Linux
by Torsten Bergmann March 11, 2010

March 11, 2010

Hey - you can now print yourself a certificate! See [1] >Can we merge our respective posts and put this on the Pharo wiki ? Why, I would put it on squeakvm.org if the documentation there is not up to date. Just ask David T. Lewis or post to the vm-dev list so your blog posts can be linked/included. >Do you know if there's an equivalent tutorial for windows ? Yes, again see http://www.squeakvm.org/win32/ >I will try with the svn trunk. On windows there are two ways: 1. Using SVN trunk, the squeakvm.org description and the vmmaker metacello config. 2. easily grab the zipped sources of the latest release without regenerating using VMMaker. (Andreas released version 3.11.8 yesterday, see [2]). First is more fun, second is easier. Note that you always get a Squeak VM. If you want to build a Pharo VM you have to additionally exchange ressources (icons, version info) to get the same results as the one I prepared for the pharo download page. BTW: I will build a new Pharo win VM based on 3.11.8 this week and will upload it to gforge similar to 2. Bye T.

[Pharo-project] [Pharo Project] Installer / Installer Monticello
by Norberto Manzanos March 11, 2010

March 11, 2010

I found some bugs in Installer and InstallerMonticello packages. Is this the properly forum to report them? If not, sorry for bother you. InstallerMonticello >>mcDetectFileBlock: The detection is made with #beginsWith:, but if you have two different packages which begins with the same string, it would detect a wrong package. Reeplaced by #copyUpToLast: $- InstallerMonticello >>mcSortFileBlock If the file has no number (it could happen, yes, and it happened to me with a file create by MonticelloConfiguration, which I didn't remember it existed) the files collection is sorted wrongly, since #asInteger will answer nil. Replaced #asInteger by #asNumber I made other modifications, but I'm not sure they are part of the developing plan of the package. Errors are logued only with an output on the Transcript, so it's very difficult to separate errors form manu other messages shown there. I add a #logErr: method which adds the string to a new instance variable in. I attached the package.

[Pharo-project] ESUG GSoC english speakers help needed!!!
by Mariano Martinez Peck March 11, 2010

March 11, 2010

Hi folks. Neither me or Janko (GSoC admins) have English as native language. Thus, there are probably some mistakes in the application text for the GSoC. The link is http://gsoc2010.esug.org/application.html If you can review them and send them to me by mail I would really appreciate it. Thanks in advance. Mariano

[Pharo-project] Google Summer Of Code 2010 news!!!
by Mariano Martinez Peck March 10, 2010

March 10, 2010

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
