Postdoc in Chile
by Alexandre Bergel March 10, 2016

March 10, 2016

Hi! We have an opportunity for doing a postdoc in Chile, in the field of software engineering and/or data visualization. I could provide a lengthy description about living in Chile, and its fantastic food, latin atmosphere, and gorgeous nature. But I will surely be far from the truth. If you want to know more about this possibility, get in touch! Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

[VIDEO TUTORIAL] Automating Image Building
by Dimitris Chloupis March 9, 2016

March 9, 2016

This one is a lengthy one but for a good reason, building images can be a tedious task but can be easily automated with the help of startup scripts and make files plus the mandatory dosage of Pharo technomagic. https://www.youtube.com/watch?v=rR4UmDoYAyQ&feature=youtu.be

Papers & Essays: * Submissions due: April 1, 2016 * First notification: May 20, 2016 * Revised papers: July 15, 2016 * Final notification: July 31, 2016 * Camera ready: August 26, 2016 # SPLASH 2016 The ACM SIGPLAN conference on Systems, Programming, Languages and Applications: Software for Humanity (SPLASH) embraces all aspects of software construction, to make it the premier conference at the intersection of programming, languages, systems, and software engineering. We invite high quality submissions describing original and unpublished work. ## OOPSLA Research Papers Papers that address any aspect of software development are welcome, including requirements, modeling, prototyping, design, implementation, generation, analysis, verification, testing, evaluation, maintenance, reuse, replacement, and retirement of software systems. Papers may address these topics in a variety of ways, including new tools (such as languages, program analyses, and runtime systems), new techniques (such as methodologies, design processes, code organization approaches, and management techniques), and new evaluations (such as formalisms and proofs, corpora analyses, user studies, and surveys). Submissions due: Wed 23 March, 2016 http://2016.splashcon.org/track/splash-2016-oopsla ## Onward! Research Papers Onward! is a premier multidisciplinary conference focused on everything to do with programming and software: including processes, methods, languages, communities, and applications. Onward! is more radical, more visionary, and more open than other conferences to ideas that are well-argued but not yet proven. We welcome different ways of thinking about, approaching, and reporting on programming language and software engineering research. Submissions due: Fri 1 April, 2016 http://2016.splashcon.org/track/onward2016/onward-2016-papers ## Onward! Essays Onward! Essays is looking for clear and compelling pieces of writing about topics important to the software community. An essay can be an exploration of a topic, its impact, or the circumstances of its creation; it can present a personal view of what is, explore a terrain, or lead the reader in an act of discovery; it can be a philosophical digression or a deep analysis. It can describe a personal journey, perhaps by which the author reached an understanding of such a topic. The subject area should be interpreted broadly and can include the relationship of software to human endeavors, or its philosophical, sociological, psychological, historical, or anthropological underpinnings.

Call about Numerical Methods in Pharo :)
by stepharo March 9, 2016

March 9, 2016

Hi guys I met Didier Besset and we had a great hacking session and discussions with Serge Stinckwich. Didier would like to help Pharo and the numerical part of it. ***Big thanks*** Didier. We would like to do several things: - Work on "Hows to" The numerical methods in Pharo is good but the gap between us and the math is too large :) so the idea is to have a series of "how to ..." - histomgram (simple, based on distribution) - Improve the SciPharo/NumPha (previously SciSmalltalk) library This morning we started to implement a ComponentPrincipalDecomposition by combining two of the objects available in SciPharo. Then we started to enhance the distributions to make sure that we can plug other distribution for having controlled random number. - Do a public call to know what is missing for you: this is this mail :) Didier would like to work on concrete cases. I love that attitude So tell us :) Hernan ?? Alex: ?? pvalue? better distribution? Vincent: covariance? CPA? Philippe: times series Serge R frames? Sami: Better random number and various distributions? - Organise a two day lectures with practices on concrete case in September with a recording session. Either at IRD Bondy or Lille. - Make sure that the Numerical Method book will get on lulu :) with a better cover and title :) Stef

Voyage, Magritte descriptions, and nil exceptions
by Tommaso Dal Sasso March 9, 2016

March 9, 2016

Hi, I am having troubles with Voyage and Mongo. I have some Classes that I save in Mongo, say "One", "Two", and "Three". All three classes and are voyage roots, so the objects from each class are stored in different collections. One objects has a reference to Two or Three objects. The problem arises when I use a Magritte description and define a Mongo container to optimize the storage: since each class is stored in its own collection, there is no point in storing the #instanceOf attribute as well. Two>>mongoContainer <mongoContainer> ^ VOMongoContainer new kind: Two; yourself If I add this method, when I try to load an object One, I get the exception: "KeyNotFound: key #nil not found in SystemDictionary". It looks like Voyage is not able to understand the type of the objects stored in the collection Two, when loaded from a reference. Am I missing something? Do I need to specify something more to make it work? I reproduced the scenario in an image that can be downloaded here: https://dl.dropboxusercontent.com/u/11506662/VoyageMongo-Link-Test.zip Do you have any idea? Should I report this on the issue tracker? Thanks! Tommaso

AsciiDoc is an exporter like Pillar, you can export you asciidoc file to pdf or something else. For the moment, this format allows generate files in format that Pillar can't know. I hope I answer your question

View a class with inherited variables/methods
by Esteban A. Maringolo March 8, 2016

March 8, 2016

Is there a way to view a class with all the inherited instance variables and/or methods? I'm trying to understand some code, and because the inheritance tree is not shallow, I'd like to see all the variables it has (both own and inherited). Regards! Esteban A. Maringolo

[Ann] DemoFFI
by Pierce Ng March 8, 2016

March 8, 2016

Hi all, I've published libffidemo on Github, https://github.com/PierceNg/libffidemo, and DemoFFI on STH, http://smalltalkhub.com/#!/~PierceNg/DemoFFI. Together, they show how to use Pharo 5's Unified FFI to obtain an "opaque" pointer to a C-level struct, in the two usual styles: passing in a pointer pointer as a parameter, and via a pointer returned by a C function. They also show how to retrieve an integer through the opaque pointer in two usual styles: passing in a pointer to integer as a parameter, which involves creating an integer value holder on the Smalltalk side, and via an integer returned by a C function. Apart from that, the library does nothing. :-) To compile libffidemo for Pharo's use: $ gcc -shared -m32 -o libffidemo.so libffidemo.c I wrote these to figure out how to port NBSQLite3 from NativeBoost to the new FFI. I hope others will find them helpful too. Pierce

I once reported a bug for OSProcess on MacOS https://pharo.fogbugz.com/f/cases/16944/OSProcess-stdout-is-not-returned-ba… Still experience the same problem, is this suppose to be fixed with new OSProcess ?

adding credentials to a repo via a playground script
by Peter UhnÃ¡k March 8, 2016

March 8, 2016

Hi, is it possible to add credentials to an existing repo via a script? I've tried something like ~~~~~~~~~~~~~~~~~~~~~~~~~ |repo| repo := MCSmalltalkhubRepository allInstances detect: [ :each | each location includesSubstring: 'Pharo50Inbox' ]. repo user: 'peteruhnak'; password: '******' ~~~~~~~~~~~~~~~~~~~~~~~~~~ but it has no effect. Thanks, Peter
