The Semantic Web brings a powerful set of concepts, standards and ideas that are already changing the shape of the Web. However, in order to put these notions into practice we need to translate them into code. That is why the broad notion of programming th ...
Just-in-time (JIT) compilation of running programs provides more optimization opportunities than offline compilation. Modern JIT compilers, such as those in virtual machines like Oracle's HotSpot for Java or Google's V8 for JavaScript, rely on dynamic prof ...
The Scala compiler uses ASTs (abstract syntax trees) as an intermediate representation before generating bytecode. With the development of Scala macros which expand trees at compile time, being able to access, modify and recompose ASTs within the compilati ...
Common subexpression elimination is a well-known compiler optimisa- tion that improves running time of compiled applications by avoiding the repetition of the same computation. Although it has been implemented on a low level such as bytecode, it misses mul ...
We present short programs that demonstrate the unsoundness of Java and Scala’s current type systems. In particular, these programs provide parametrically polymorphic functions that can turn any type into any type without (down)casting. Fortunately, paramet ...
Generics on the Java platform are compiled using the erasure transformation, which only supports by-reference values. This causes slowdowns when generics operate on primitive types, such as integers, as they have to be transformed into reference-based obje ...
We present a new code assistance tool for integrated development environments. Our system accepts as input free-form queries containing a mixture of English and Java, and produces Java code expressions that take the query into account and respect syntax, t ...
We consider two approaches for building component-based systems, which we call respectively architecture-based and architecture-agnostic. The former consists in describing coordination constraints in a purely declarative manner through parameterizable glue ...
Architectures allow shifting the focus of developers from low-level code to high-level structures ensuring coordination in component-based systems. If the architecture description language is expressive enough, it is possible to describe architectures in a ...
This work demonstrates an application of different real-time speech technologies, exploited in an online gaming scenario. The game developed for this purpose is inspired by the famous television based quiz-game show, “Who wants to be a millionaire”, in whi ...
