We invite high quality submissions describing original and unpublished work.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.

Re: [Pharo-users] [Pharo-dev] Call about Numerical Methods in Pharo :)

Hi Alex, This binding allows to execute (almost) any function provided by R via Native Calls. You can find some documentation here: http://smalltalkhub.com/#!/~VincentBlondeau/RProjectConnector I just released a new stable version, you should be able to load it from the catalog (Pharo40 only). However, you must install R and copy the libraries in the VM folder (see doc). And it is working only with pre-spur images (the migration to FFI has to be done). Try to run the tests (in RConnector package). Iff they are green, you succeeded to configure the binding. And you can plot the famous Iris Data: iris := 'eval' asREval: { RObject findVar: 'iris' }. 'plot' asREval: {(iris at: 'Petal.Length'). (iris at: 'Petal.Width'). (#pch -> 21). (#xlab -> 'length'). (#ylab -> 'Width'). (#bg ->((iris at: 'Species') collect: [ :value | {'red'. 'green3'. 'blue'} at: value ])). (#main -> 'Edgar Anderson''s Iris Data')}. plot(iris$Petal.Length, iris$Petal.Width, pch=21, bg=c("red","green3","blue")[unclass(iris$Species)], main="Edgar Anderson's Iris Data") is the genuine R function. And inspect them: iris inspect You can use any collection of pharo and put it as argument, it should do the boxing automatically. Warning: while testing new functions, donât forget to save because evaluation of a non-existing R function throws a error that is not caught and makes Pharo crashing.

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.
