In this note, I propose two extensions to the Java virtual machine (or VM) to allow dynamic languages such as Dylan, Scheme and Smalltalk to be efficiently implemented on the VM. These extensions do not affect the performance of pure…

This paper presents an evolution of a simulation environment where situations in which a DDB should maintain data integrity are modeled and implemented. These situations include failures taking place during transactions, and the focus is mainly on the utilization and…

Acantholybas steinbaueri, a brachypterous new species, is described and illustrated from Java (Bali Island and Dammerman). The genus Acantholybas is redescribed, and a key to the four known species is provided.
