[Pharo-project] moving a ChangeSet into Monticello
by Francisco Garau March 30, 2012

March 30, 2012

Sorry for the basic question about Monticello. I have 3 ChangeSets which I'd prefer to keep separate -- how can I put them into a central code repository? I've found no easy way of telling Monticello to read an existing ChangeSet. Any hint is appreciated. - Francisco

Re: [Pharo-project] direct object manipulation

Here's an extract of an email i've sent to the list when i successfully used Cairo on Mac. How is Roassal being rendered now? Using FormCanvas? If you have some screenshots would be nice. Saludos, Fernando pd: Regarding the build, after a lonnnngg series of errors, i also managed to build universal binaries of Cairo, using MacPorts (brew just doesn't ease the task of creating 32 bit libraries). sudo port cairo +universal, worked for me, taking at least 30 min to build. ATTENTION: Before entering the port cairo install command, I've had to manually install appleGcc4.2, found @ [1] (file name gcc-42-5666.3-darwin11.pkg. Given that i have Lion, XCode4.2, and if you just allow macports to build appleGcc4.2, it will run a process that consumes resources and finally stalls your computer! I've attached a screen shot that may help somebody else, for setting up the examples. Using NativeBoost Cog VM for Mac, downloadable from NativeBoost site or Jenkins. Great work Javier, and Igor! I'm looking forward to implement a Text editor using Cairo+Pango + "my new morphic".

[Pharo-project] SciSmalltalk
by Serge Stinckwich March 29, 2012

March 29, 2012

Dear all, we already discuss about that in the moose and pharo mailing-list. Maybe this is too late, but please find a small proposal for gsoc 2012 below. ================================================================ Name: SciSmalltalk Level: Intermediate Possible mentor: Serge Stinckwich Possible second mentor: ? Description Smalltalk has at that time no equivalent to mathematical libraries like NumPy, SciPy (Python) or SciRuby (Ruby). The goal of the SciSmalltalk project is to develop an open-source library of mathematical for the Smalltalk programming language (MIT Licence). Technical Details The development of this project is to be done in Pharo Smalltalk, but the code should be portable to other Smalltalk flavors. Numerous Smalltalk projects provide already some basic functionalities (complex and quaternions extensions, random number generator, fuzzy algorithms, LAPACK linear algebra package, Didier Besset's numerical methods, ...). A first task will be to do an audit of all the existing projects that provide some mathematical stuff and build a Pharo Configuration to load them in a fresh Pharo Smalltalk image. After that, the student help by his/her mentors will decide what are the numeric algorithms to develop in priority. The student will need to know some basic numeric algorithms usually found in such libraries. Units tests should also be provided. Benefits to the Student The student will help the Smalltalk community in a very concrete way. The student will learn to design well-designed code with tests. Benefits to the Community Having a package providing more elaborate numeric libraries is really important to develop the use Smalltalk in new domains (robotics, high performance computing, computer vision, bio-computing, ...). The lack of numeric librairies hamper the use of the Smalltalk in a scientific context at the moment. An another goal of this project is to develop a community of people interested by these topic.

Millions of R&D money? Klatt is really really old... it's not state of the art at all. Of course, all the technology that is really good is not free. IMHO we should remove the Klatt plugin from the VM. Marcus -- Marcus Denker -- http://marcusdenker.de

The attendees are both engineers using Smalltalk in business and students and teachers using Smalltalk both for research and didactic purposes. This year's edition of the largest European Smalltalk event will include: - The regular Smalltalk developers conference with renowned invited speakers - a Smalltalk camp that proved fruitful for interactions and discussions (August 25-26) - 9th edition of the Innovation Technology Awards where prizes will be awarded to authors of best pieces of Smalltalk-related projects - IWST: an international workshop on Smalltalk and dynamic languages You can support the ESUG conference in many different ways: - Sponsor the conference. New sponsoring packages are described at http://www.esug.org/About/SupportESUG - Submit a talk, a software or a paper to one of the events. See below. - Attend the conference. We'd like to beat the previous record of attendance (170 people at Amsterdam)! - Students can get free registration and hosting if they enroll into the the Student Volunteers program. See below. 1) Developers Forum: International Smalltalk Developers Conference ---------------------------------------------------------------------- This year we are looking for YOUR experience on using Smalltalk. In addition, we are looking for tutorials. The list of topics includes, but is not limited to the following: - XP practices - Development tools - Experience reports - Model driven development - Web development - Team management - Meta-Modeling - Security - New libraries & frameworks - Educational material - Embedded systems and robotics - SOA and Web services - Interaction with other programming languages Submissions due on 15 June 2012 Notification of acceptance on 25 June 2012 How to submit?
