Smalltalkhub & Squeaksource3
by Mark Bratcher June 16, 2016

June 16, 2016

A couple of easy ones: 1) Does smalltalkhub.com support private projects (used, e.g., for CI)? I've seen a couple of posts on random forums dating back a couple of years indicating that it did, but when I went to create a project, I didn't see an option to make it private. 2) Is Squeaksource 3 (http://ss3.gemtalksystems.com/ss) currently maintained? It still says "public alpha" and latest comments anywhere or submissions to their tracker are old. Who is the current owner? Thanks Mark

[ANN] pharo-vm on ubuntu updated
by Norbert Hartl June 16, 2016

June 16, 2016

There are new pharo vms (non-spur) available with updated sources. As a side effect the pharo vm is now available on ubuntu 16.04 LTS as well. The created vms are in the unstable channel of the pharo ppa. It would be good if a few people could test the packages. If nothing is broken with the packages I can move them to the stable channel. To test the packages you need to do: $ apt-add-respository ppa:pharo/unstable $ apt-get update $ apt-get install pharo-vm-core or $ apt-get install pharo-vm-desktop I hope the packages for the spur vm don't take a long time to come along as well. Happy to get feedback, Norbert

Submission deadline: Thu 30 Jun 2016 Website: http://2016.splashcon.org/track/splash-2016-ds ## Student Research Competition Continuing the successes of previous years, SPLASH is again hosting an ACM SIGPLAN Student Research Competition (ACM SRC). The competition is an internationally-recognized venue that enables undergraduate and graduate students to experience the research world and to share their research results with other students and SPLASH attendees. The competition has separate categories for undergraduate and graduate students and awards prizes to the top three students in each category. The ACM SIGPLAN Student Research Competition shares the Poster sessionâs goal to facilitate interaction with researchers and industry practitioners, providing both sides with the opportunity to learn of ongoing, current research. Additionally, the Student Research Competition gives students experience with both formal presentations and evaluations. Submission deadline: Mon 15 Aug 2016 Website: http://2016.splashcon.org/track/splash-2016-src ## PLMW: Programming Language Mentoring Workshop The purpose of Programming Languages Mentoring Workshop (PLMW) is to give promising students who consider pursuing a graduate degree in this field an overview of what research in this field looks like and how to get into and succeed in graduate school. In other words, a combination whirlwind tour of this research area, networking opportunity, and how-to-succeed guide. The program of PLMW will include talks by prominent researchers of the field of programming languages and software engineering providing an insight in their research. To learn more about PLMW, please see the SIGPLAN PLMW web page (http://www.sigplan.org/Conferences/PLMW/) Application deadline: Sun 14 Aug 2016 Website: http://2016.splashcon.org/track/splash-2016-plmw ## Posters The SPLASH Poster track provides an excellent forum for authors to present their recent or ongoing projects in an interactive setting, and receive feedback from the community. We invite submissions covering any aspect of programming, systems, languages and applications. The goal of the poster session is to encourage and facilitate small groups of individuals interested in a technical area to gather and interact. It is held early in the conference, to promote continued discussion among interested parties. Submission deadline: Fri 8 Jul 2016 Website: http://2016.splashcon.org/track/splash-2016-posters Collocated Conferences and Symposia =================================== ## GPCE: Generative Programming: Concepts & Experiences Generative and component approaches and domain-specific abstractions are revolutionizing software development just as automation and componentization revolutionized manufacturing. Raising the level of abstraction in software specification has been a fundamental goal of the computing community for several decades. Key technologies for automating program development and lifting the abstraction level closer to the problem domain are Generative Programming for program synthesis, Domain-Specific Languages (DSLs) for compact problem-oriented programming notations, and corresponding Implementation Technologies aiming at modularity, correctness, reuse, and evolution. As the field matures Applications and Empirical Results are of increasing importance. The International Conference on Generative Programming: Concepts & Experiences (GPCE) is a venue for researchers and practitioners interested in techniques that use program generation, domain-specific languages, and component deployment to increase programmer productivity, improve software quality, and shorten the time-to-market of software products. In addition to exploring cutting-edge techniques of generative software, our goal is to foster further cross-fertilization between the software engineering and the programming languages research communities. Abstract submission deadline: Fri 17 Jun 2016 Paper submission deadline: Fri 24 Jun 2016 Website: http://www.gpce.org Call for papers (pdf): http://conf.researchr.org/getImage/gpce-2016/orig/GPCE16+-+Call+for+Papers.… Twitter: https://twitter.com/gpceconf Facebook: https://www.facebook.com/GPCEConference/ ## Scala Symposium The Scala Symposium is a forum for researchers and practitioners to share new ideas and results of interest to the Scala programming language community. We welcome a broad spectrum of research topics in many formats, going from student talks all the way to full 10-page research papers, indexed by the ACM Digital Library. Abstract submission deadline: Sun 17 Jul 2016 Paper submission deadline: Mon 25 Jul 2016 Website: http://2016.splashcon.org/track/scala-2016 ## SLE: Software Language Engineering Software Language Engineering (SLE) is the application of systematic, disciplined, and measurable approaches to the development, use, deployment, and maintenance of software languages. The term âsoftware languageâ is used broadly, and includes: general-purpose programming languages; domain-specific languages (e.g. BPMN, Simulink, Modelica); modeling and metamodeling languages (e.g. SysML and UML); data models and ontologies (e.g. XML-based and OWL-based languages and vocabularies). SLE aims to be broad-minded and inclusive about relevance and scope. We solicit high-quality contributions in areas ranging from theoretical and conceptual contributions to tools, techniques, and frameworks in the domain of language engineering. Topics relevant to SLE cover generic aspects of software languages development rather than aspects of engineering a specific language. Abstract submission deadline: Fri 17 Jun 2016 Paper submission deadline: Fri 24 Jun 2016 Website: http://2016.splashcon.org/track/sle-2016-papers Twitter: https://twitter.com/sleconf Facebook https://www.facebook.com/SLEconference/ Workshops ========= SPLASH'16 will host a record number of 16 workshops: ## AGERE! Programming based on Actors, Agents, and Decentralized Control The AGERE! workshop is aimed at focusing on programming systems, languages and applications based on actors, active/concurrent objects, agents and â more generally â high-level programming paradigms promoting a mindset of decentralized control in solving problems and developing software. The workshop is designed to cover both the theory and the practice of design and programming, bringing together researchers working on models, languages and technologies, and practitioners developing real-world systems and applications. Abstract submission deadline: Mon 1 Aug 2016 Paper submission deadline: Mon 15 Aug 2016 Website: http://2016.splashcon.org/track/agere2016 ## DSLDI: Domain-specific Language Design and Implementation Domain-Specific Language Design and Implementation (DSLDI) is a workshop intended to bring together researchers and practitioners interested in discussing how DSLs should be designed, implemented, supported by tools, and applied in realistic contexts. The focus of the workshop is on all aspects of this process, from soliciting domain knowledge from experts, through the design and implementation of the language, to evaluating whether and how a DSL is successful. More generally, we are interested in continuing to build a community that can drive forward the development of modern DSLs. Submission deadline talk proposals: Mon 1 Aug 2016 Website: http://2016.splashcon.org/track/dsldi2016 ## DSM: Domain-Specific Modeling Domain-specific languages provide a viable and time-tested solution for continuing to raise the level of abstraction, and thus productivity, beyond coding, making systems development faster and easier. When accompanied with suitable automated modeling tools and generators it delivers to the promises of continuous delivery and devops. In domain-specific modeling (DSM) the models are constructed using concepts that represent things in the application domain, not concepts of a given programming language. The modeling language follows the domain abstractions and semantics, allowing developers to perceive them- selves as working directly with domain concepts. Together with frameworks and platforms, DSM can automate a large portion of software production. Submission deadline: Mon 15 Aug 2016 Website: http://2016.splashcon.org/track/dsm2016 ## FOSD: Feature-oriented Software Development Feature orientation is an emerging paradigm of software development. It supports the automatic generation of large-scale software systems from a set of units of functionality, called features. The key idea of feature-oriented software development (FOSD) is to explicitly represent similarities and differences of a family of software systems for a given application domain (e.g., database systems, banking software, text processing systems) with the goal of reusing software artifacts among the family members. Submission deadline: Mon 1 Aug 2016 Website: http://www.fosd.net/workshop2016 Call for papers: http://conf.researchr.org/getImage/FOSD-2016/orig/FOSD+2016+-+CFP.pdf ## ITSLE: Industry Track Software Language Engineering Industry Track for Software Language Engineering (ITSLE) is a workshop to bring together practitioners and researchers from industry and academia working on the area of software language engineering. Domain Specific Languages (DSLs) and Model-Driven Software Engineering (MDSE) techniques are being developed and used broadly in industry. However, as the size and complexity of software systems steadily increase, so does the cost of maintaining and improving the DSL and MDSE techniques and tools. It introduces new challenges such as language co-evolution, maintainability of legacy software using older version of DSLs and MDSE techniques, and extendability and scalability of these techniques. Some of these challenges have been addressed by the SLE research community and some remain unsolved. Submission deadline: Mon 1 Aug 2016 Website: http://2016.splashcon.org/track/itsle2016 ## LWC@SLE: Language Workbench Challenge Language workbenches are tools for software language engineering. They distinguish themselves from traditional compiler tools by providing integrated development environment (IDE) support for defining, implementing, testing and maintaining languages. Not only that, languages built with a language workbench are supported by IDE features as well (e.g., syntax highlighting, outlining, reference resolving, completion etc.). As a result, language workbenches achieve a next level in terms of productivity and interactive editor support for building languages, in comparison to traditional batch-oriented, compiler construction tools. The goal of this workshop is twofold. First: exercise and assess the state-of-the-art in language workbenches using challenge problems from the user perspective (i.e. the language designer). Second: foster knowledge exchange and opportunities for collaboration between language workbench implementors and researchers. Submission deadline of solutions: Mon 1 Aug 2016 Website: http://2016.splashcon.org/track/lwc2016 ## META The Metaâ16 workshop aims to bring together researchers working on metaprogramming and reflection, as well as users building applications, language extensions such as contracts, or software tools. With the changing hardware and software landscape, and increased heterogeneity of systems, metaprogramming becomes an important research topic to handle the associate complexity once more. Contributions to the workshop are welcome on a wide range of topics related to design, implementation, and application of metaprogramming techniques, as well as empirical studies on and typing for such systems and languages. Abstract submission: Wed 27 Jul 2016 Paper submission: Mon 1 Aug 2016 Website: http://2016.splashcon.org/track/meta2016 ## Mobile! Mobile application use and development is experiencing enormous growth, and by 2016 more than 200 billion apps have been downloaded. The mobile domain presents new challenges to software engineering. Mobile platforms are rapidly changing, with diverse capabilities including various input modes, wireless communication types, on-device memory and disk capacities, and sensors. Applications function on wide ranges of platforms, requiring scaling according to hardware. Many applications interact with third-party services, requiring application development with effective security and authorization processes for those dataflows. âBring your own deviceâ policies pose security challenges including employer and employee data privacy. Developing secure mobile applications requires new tools and practices such as improved refactoring tools for hybrid applications; polyglot applications; and testing techniques for multiple devices. This workshop aims to establish a community of researchers and practitioners, leading to further research in mobile development. Paper submission deadline: Mon 1 Aug 2016 Website: http://2016.splashcon.org/track/mobile2016 ## NOOL: New Object-Oriented Languages NOOL-16 is a new unsponsored workshop to bring together users and implementors of new(ish) object oriented systems. Through presentations, and panel discussions, as well as demonstrations, and video and audiotapes, NOOL-16 will provide a forum for sharing experience and knowledge among experts and novices alike. We invite technical papers, case studies, and surveys in the following areas, related to theory of object oriented programming, new languages, implementation of languages, tools and environment, applications and related work. Abstract submission deadline: Thu 1 Sep 2016 Website: http://2016.splashcon.org/track/nool2016 ## PLATEAU: Workshop on Evaluation and Usability of Programming Languages and Tools Programming languages exist to enable programmers to develop software effectively. But how efficiently programmers can write software depends on the usability of the languages and tools that they develop with. The aim of this workshop is to discuss methods, metrics and techniques for evaluating the usability of languages and language tools. The supposed benefits of such languages and tools cover a large space, including making programs easier to read, write, and maintain; allowing programmers to write more flexible and powerful programs; and restricting programs to make them more safe and secure. PLATEAU gathers the intersection of researchers in the programming language, programming tool, and human-computer interaction communities to share their research and discuss the future of evaluation and usability of programming languages and tools. Paper submission deadline: Mon 1 Aug 2016 Website: http://2016.splashcon.org/track/plateau2016 ## Parsing@SLE Parsing@SLE 2016 is the fourth annual workshop on parsing programming languages. The intended participants are the authors of parser generation tools and parsers for programming languages and other software languages. For the purpose of this workshop âparsingâ is a computation that takes a sequence of characters as input and produces a syntax tree or graph as output. This possibly includes tokenization using regular expressions, deriving trees using context-free grammars, and mapping to abstract syntax trees. The goal is to bring together todayâs experts in the field of parsing, in order to explore open questions and possibly forge new collaborations. The topics may include algorithms, implementation and generation techniques, syntax and semantics of meta formalisms (BNF), etc. We expect to attract participants that have been or are developing theory, techniques and tools in the broad area of parsing. Abstract submission deadline: Fri 9 Sep 2016 Website: http://2016.splashcon.org/track/parsing2016 ## REBLS: Reactive and Event-based Languages & Systems Reactive programming and event-based programming are two closely related programming styles that are becoming ever more important with the advent of advanced HPC technology and the ever increasing requirement for our applications to run on the web or on collaborating mobile devices. A number of publications on middleware and language design â so-called reactive and event-based languages and systems (REBLS) â have already seen the light, but the field still raises several questions. For example, the interaction with mainstream language concepts is poorly understood, implementation technology is in its infancy and modularity mechanisms are almost totally lacking. Moreover, large applications are still to be developed and patterns and tools for developing reactive applications is an area that is vastly unexplored. Paper submission deadline: Mon 1 Aug 2016 Website: http://2016.splashcon.org/track/rebls2016 ## RUMPLE: ReUsable and Modular Programming Language Ecosystems The RUMPLEâ16 workshop is a venue for discussing a wide range of topics related to modular approaches to programming language implementation, extensible virtual machine architectures, as well as reusable runtime components such as dynamic compilers, interpreters, or garbage collectors. One of the main goals of the workshop is to bring together both researchers and practitioners and facilitate effective sharing of their respective experiences and ideas. We welcome presentation proposals in the form of extended abstracts discussing experiences, work-in-progress, as well as future visions from the academic as well as industrial perspective. Extended abstract submission deadline: Mon 1 Aug 2016 Website: http://2016.splashcon.org/track/rumple2016 ## SA-MDE: Tutorial on MDD with Model Catalogue and Semantic Booster With the model-driven development (MDD) approach to software, rather than building each system from scratch, one specifies a metamodel covering a whole class of similar systems, provides a universal generator to transform metamodel instances into executable programs, and specifies each system by a higher-level model conforming to the metamodel. When the application domain concerns semantically rich datasetsâwith structured entities, interlinked data, and sophisticated integrity constraintsâthen the MDD tools should support this richness: in the metamodel, in individual system models, and in the generation process. In this tutorial, we present the Model Catalogue and Semantic Booster, tools respectively for curating and exploiting semantically rich data in a MDD workflow, which are under development as part of ALIGNED. Participants will learn what the tools can do, gain hands-on experience with using them, and be able to contribute challenges and suggestions for future development. Website: http://2016.splashcon.org/track/samde2016 ## SEPS: Software Engineering for Parallel Systems This workshop provides a stable forum for researchers and practitioners dealing with compelling challenges of the software development life cycle on modern parallel platforms. The increased complexity of parallel applications on modern parallel platforms (e.g. multicore/manycore, distributed or hybrid) requires more insight into development processes, and necessitates the use of advanced methods and techniques supporting developers in creating parallel applications or parallelizing and re-engineering sequential legacy applications. We aim to advance the state of the art in different phases of parallel software development, covering software engineering aspects such as requirements engineering and software specification; design and implementation; program analysis, profiling and tuning; testing and debugging. Paper submission deadline: Mon 1 Aug 2016 Website: http://2016.splashcon.org/track/seps2016 ## VMIL: Virtual Machines and Intermediate Languages The VMIL workshop is a forum for research in virtual machines and intermediate languages. It is dedicated to identifying programming mechanisms and constructs that are currently realized as code transformations or implemented in libraries but should rather be supported at VM level. Candidates for such mechanisms and constructs include modularity mechanisms (aspects, context-dependent layers), concurrency (threads and locking, actors, capsules, processes, software transactional memory), transactions, development tools (profilers, runtime verification), etc. Topics of interest include the investigation of which such mechanisms are worthwhile candidates for integration with the run-time environment, how said mechanisms can be elegantly (and reusably) expressed at the intermediate language level (e.g., in bytecode), how their implementations can be optimized, and how virtual machine architectures might be shaped to facilitate such implementation efforts. Paper submission deadline: Mon 1 Aug 2016 Website: http://2016.splashcon.org/track/vmil2016 ## WODA: Workshop on Dynamic Analysis The International Workshop on Dynamic Analysis (WODA) is the place where researchers interested in dynamic analysis and related topics can meet and discuss current research, issues, and trends in the field. WODA exists since 2003 and has been co-located with several different SE/PL conferences in the past, including ICSE, ISSTA, ASPLOS, and SPLASH. See https://sites.google.com/site/scwoda/ for the history of WODA. The 2016 edition of WODA will be a mix of invited talks by high-visibility researchers in the community and presentations of submitted workshop papers. Submission deadline: Fri 19 Aug 2016 Website: http://2016.splashcon.org/track/woda2016 # SPLASH Supporters SPLASH'16 is kindly supported by the following organizations: - ACM: http://www.acm.org/ - SIGPLAN: http://www.sigplan.org/ - LogicBlox (Gold): http://www.logicblox.com/ - Oracle (Silver): http://www.oracle.com/index.html - TU Delft (Silver): http://tudelft.nl/ - Huawei (Bronze): http://www.huawei.com/en/ - Facebook (Bronze): https://research.facebook.com/ - IBM Research (Bronze): http://www.research.ibm.com/ - Google (Bronze): https://www.google.com Want to support SPLASH'16?

The #compile: selector
by Mark Bratcher June 15, 2016

June 15, 2016

When using the #compile: selector to dynamically create a selector, is there a way (e.g., a pragma) to specify the category for the dynamic selector in a way that Pharo will see it? I tried, for example: s := String new writeStream. s nextPutAll: 'foo' ; cr ; nextPutAll: ' <category: ''accessor''>' ; cr ; nextPutAll: ' ^fooVar' ; cr. Foo compile: s contents. Which created the following selector just fine: foo <categor: 'accessor'> ^ fooVar But Pharo considers it uncategorized. I'm just wondering if it's possible. Thanks Mark

Pharo 5 on FreeBSD - no luck
by Petr Fischer June 15, 2016

June 15, 2016

Hello, trying to install Pharo on my FreeBSD (11-CURRENT 64bit) with no luck :( Facts: 1) I can run Linux (even 64bit Linux ELF) binaries on FreeBSD 2) but I can't use precompiled Linux 32binaries from Pharo.org, because there is no 32libs (32bit linux libs) support on 64bit FreeBSD 3) tried build from https://github.com/pharo-project/pharo-vm - no luck, because newImage script downloads 5.0 image and Linux VM (!) for intermediate VMMaker build (I can't build Pharo without working Pharo) 4) tried latest prebuild 64 bit Cog Spur Linux VM from http://www.mirandabanda.org/cogblog/downloads/ (cogspur64linuxht) - no luck - I don't know what the "squeak" start SH script is doing and it's intended for Linux Is actual build documentation for latest 64 bit Cog-Spur-something-something-VM somewhere? Will be FFI (New-Native-something-something-FFI) working fine under FreeBSD (another unix), or will be some low-level core C porting needed? I can help with adapting build scrits also for FreeBSD - this OS is small, fast, robust and secure (there is ZFS, Jails for isolation, everything is simple etc etc) - perfect for running Pharo images on server side - I really like this combo (BSD+Smalltalk). Thanks, Petr Fischer

Dependency error trying to submit a proposed enhancement to Pharo 5.0 on Smalltalkhub.com
by Mark Bratcher June 15, 2016

June 15, 2016

I am trying to push a simple enhancement to Pharo50inbox on smalltalkhub.com. I am running Pharo 5.0 (downloaded within the last month) on Windows 10. I started from a completely clean image, made my small change (about 5 lines in an existing Pharo 5.0 class), and I followed all of the directions to contribute a proposed fix <http://pharo.org/contribute-propose-fix> very carefully. All the steps went smoothly, as expected, until it came time to pull and verify the slice. Here is a snapshot of my Monticello browser right BEFORE pushing <http://i.stack.imgur.com/Zv2bZ.jpg> the suggested change slice. What is listed as dirty are the SLICE itself (containing Regex-Core (TheIntegrator.38)) and the package itself, listed separately, as dirty (Regex-Core (TheIntegrator.38)). As indicated in the instructions, I highlighted the SLICE and did a Save to the `http://smalltalkhub.com/mc/Pharo/Pharo50Inbox/main` repository. That went smoothly. After clicking save, Monticello showed <http://i.stack.imgur.com/BYfVf.jpg> that the SLICE (with subpackage) and the separately listed package were no longer marked dirty and version had been bumped with my name associated (both now called, "Regex-Core (MarkBratcher.39)"). The dialog that popped up after the save indicated that there is a dependency on `Regex-Core (MarkBratcher.39)` which surprised me a bit, but since I followed the instructions exactly, I wasn't concerned yet... When I tried to verify, I started with a clean image again (as recommended in the instructions, opened Monticello, opened the Pharo50Inbox repository, found and highlighted my slice, and clicked "Load". Then I got an error that there was a missing dependency on the package: `Regex-Core (MarkBratcher.39)`. I thought that package was integrated as part of the SLICE. If I followed the linked instructions precisely, what am I missing?

Interviews are a big cost for the employer and usually by the time you get there, they already think they want you. The interviewer already has an agenda basically verifying things they have already learnt about you. What you want to do is get it on the agenda pre-interview, to help you get through the front door to interview stage. The *very* best thing you can do is write a blog about your experiences, then link to it on your resume. The interviewer *will* review it and they "get to know you" - which really helps you stand out in their mind from all the other pieces of paper that float across their desk. Take a few articles to write about your journey discovering Pharo, intermediate experience, what makes it stand out from other environments and culminate in describing your feelings about making your first contribution and *why* you've chosen to do so. You might even get your post linked from Pharo Weekly. btw, after your contribution is integrated, submit your details to be added to pharo contributors http://pharo.org/about > On positive feedback.

I don't really want to be the one to discourage hot hostesses ;) but I think this would come across a bit false - like buying your way to fame. Your money is probably better spent on donating a few pizzas to the hacking sessions that often accompany these events. Or offer your time and effort into help organise the event (plus you end up interfacing with a lot of people.) If you a up for public speaking, be the one introducing the speakers, or get a ten minute presentation slot just to introduce yourself and give a newcomers perspective, for other newcomers in the audience to identify with and perhaps be encouraged to follow the same path. cheers -ben > > Mentoring.

DBXTalk/Garage: GAMySQLDriver#execute: raises exception when int field is NULL
by Mark Bratcher June 14, 2016

June 14, 2016

Hello Not sure where else to post this. I have posted what looks like a bug in the GAMySQLDriver#execute: selector. Here is the bug report on tracker: https://github.com/guillep/DBXTalk/issues/8. But there is very, very little activity there or in the DBXTalk Google discussion group. Is DBXTalk/Garage still considered a supported means of interfacing to an existing database (like MySQL or PostgreSQL)? If so, is there something Iâm doing wrong as shown in the tracker post, or is there a known bug? Thanks ------- Sent from Mail for Windows 10
