Proceedings of the 2013 companion publication for conference on Systems, programming, & applications: software for humanity

It is our great pleasure to welcome you to Indianapolis and SPLASH 2013, the umbrella venue for the 28th OOPSLA, plus Onward!, Wavefront, and the Dynamic Languages Symposium. Moreover, SPLASH 2013 is proud to host the ACM SIGPLAN Conference on Generative Programming: Concepts & Experiences (GPCE), co-locating with the International Conference on Software Language Engineering (SLE). SPLASH this year revives the former educator's symposium in its new guise as SPLASH-E, for discussion of Computer Science education uniquely embedded within the culture of visionary research and practice embodied by OOPSLA, Onward!, and Wavefront. SPLASH-E is timely in that it coincides with the finalization of the ACM/IEEE Computer Science Curriculum 2013. This year also sees the return to SPLASH of tutorials and tech-talks, plus a new twist in the form of the synergistic SPLASH-I as a forum for acclaimed speakers from industry, all offered free to SPLASH attendees. Drawing on the long tradition of OOPSLA, and with the addition of Onward! and Wavefront, SPLASH embraces all aspects of software construction and delivery to make it the premier conference at the intersection of programming, languages, and software engineering. OOPSLA was the incubator for CRC cards, CLOS, design patterns, Self, the agile methodologies, serviceoriented architectures, wikis, Unified Modeling Language (UML), test driven design (TDD), refactoring, Java, dynamic compilation, and aspect-oriented programming, just to name a few. Onward! focuses 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 not yet well-proven but well-argued ideas. Wavefront is about how industry applies the lessons learned from the software development community in deploying today's software and systems, and how the community can learn from what is happening in the trenches of software engineering. The Dynamic Languages Symposium is the place where researchers and practitioners come together to discuss the new crop of wildly successful dynamic languages, their implementation, and their applications. Guest conferences at SPLASH this year include GPCE and SLE. The ACM SIGPLAN 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. The International Conference on Software Language Engineering (SLE) is devoted to topics related to artificial languages in software engineering. SLE's mission is to encourage and organize communication among communities that have traditionally looked at software languages from different and yet complementary perspectives. This year we are extremely fortunate to have four keynote speakers who tap into broad and deep SPLASH themes. Kathryn McKinley looks at the impact that heterogeneous hardware is having on the design and implementation of software abstractions for parallelism. Greg Wilson asks why the gap between research and practice remains so wide, and suggests how to narrow it. Molham Aref explores declarative programming for the cloud to combine rapid prototyping with performance in the deployment of large-scale cloud applications. Gilad Bracha ponders the history of innovation in programming languages and what is yet to come, asking how the elegance of Lisp, Simula, Actors, Beta, Smalltalk and Self led to the reality of C++, Java, Javascript, Perl, Python and PHP.
