Advanced Topics In Programming Languages: Closures For Java

We propose to add Closures to the Java Programming Language. Closures simplify the use of APIs that rely on anonymous class instances, such as the concurrency APIs and callbacks. More importantly, closures support control abstractions, which are APIs that act as programmer-defined control constructs. This talk describes the proposed language extension and its design rationale, and shows how it will affect existing and future APIs.

Measuring Programmer Productivity

SLIDES

"ABSTRACT: Developers have been programming for the last 30 years in a wide variety of programming languages. Over the years, we have all developed a feeling for what it is in a programming language that makes us productive as programmers. As part of the DARPA HPCS (High Productivity Computing Systems) program, we are developing models and tools to measure programmer productivity. We will describe our data gathering process, and our effort to model programmer workflows using timed markov models. timed markov models."
