Programming as interaction: A new perspective for programming language research
In programming research, we say a lot about programs and languages, but very little about the actual process of programming. One simple trick that will make programming language research significantly more interesting is to think about programs not as expressions, but as a result of a sequence of interactions that…

The benefits and costs of writing a POSIX kernel in a high-level language
This paper presents an evaluation of the use of a high-level language (HLL) with garbage collection to implement a monolithic POSIX-style kernel. The goal is to explore if it is reasonable to use an HLL instead of C for such kernels, by examining performance costs, implementation challenges, and programmability and…
