A High-Level Programming Language for Multimedia Streaming
Liquidsoap: a High-Level Programming Language for Multimedia Streaming David Baelde1, Romain Beauxis2, and Samuel Mimram3 1 University of Minnesota, USA 2 Department of Mathematics, Tulane University, USA 3 CEA LIST – LMeASI, France Abstract. Generating multimedia streams, such as in a netradio, is a task which is complex and difficult to adapt to every users’ needs. We introduce a novel approach in order to achieve it, based on a dedi- cated high-level functional programming language, called Liquidsoap, for generating, manipulating and broadcasting multimedia streams. Unlike traditional approaches, which are based on configuration files or static graphical interfaces, it also allows the user to build complex and highly customized systems. This language is based on a model for streams and contains operators and constructions, which make it adapted to the gen- eration of streams. The interpreter of the language also ensures many properties concerning the good execution of the stream generation. The widespread adoption of broadband internet in the last decades has changed a lot our way of producing and consuming information. Classical devices from the analog era, such as television or radio broadcasting devices have been rapidly adapted to the digital world in order to benefit from the new technologies available. While analog devices were mostly based on hardware implementations, their digital counterparts often consist in software implementations, which po- tentially offers much more flexibility and modularity in their design. However, there is still much progress to be done to unleash this potential in many ar- eas where software implementations remain pretty much as hard-wired as their digital counterparts. -

We are working with the video production company North by Northwest to produce the pilot and the second episode in Spokane, Washington this spring. We plan to stream episodes on the internet with commercials in a thirty-minute format. With cash flow from the pilot and second episode we will produce four to six episodes this fall and at least twelve episodes next year. The money raised through Mainvest will be used to produce the first one or two episodes of Selling Seattle and for advertising costs, office expenses and an income for Jim McGuffin not to exceed $15,000 per episode. -

Programming Language Features for Refinement
Programming Language Features for Refinement Jason Koenig K. Rustan M. Leino Stanford University Microsoft Research [email protected] [email protected] Algorithmic and data refinement are well studied topics that provide a mathematically rigorous ap- proach to gradually introducing details in the implementation of software. Program refinements are performed in the context of some programming language, but mainstream languages lack features for recording the sequence of refinement steps in the program text. To experiment with the combination of refinement, automated verification, and language design, refinement features have been added to the verification-aware programming language Dafny. This paper describes those features and reflects on some initial usage thereof. 0. Introduction Two major problems faced by software engineers are the development of software and the maintenance of software. In addition to fixing bugs, maintenance involves adapting the software to new or previously underappreciated scenarios, for example, using new APIs, supporting new hardware, or improving the performance. Software version control systems track the history of software changes, but older versions typically do not play any significant role in understanding or evolving the software further. For exam- ple, when a simple but inefficient data structure is replaced by a more efficient one, the program edits are destructive. Consequently, understanding the new code may be significantly more difficult than un- derstanding the initial version, because the source code will only show how the more complicated data structure is used. The initial development of the software may proceed in a similar way, whereby a software engi- neer first implements the basic functionality and then extends it with additional functionality or more advanced behaviors.
