Algebraic effect handlers are a powerful means for describing effectful computations. They provide a lightweight and orthogonal technique to define and compose the syntax and semantics of different effects. The semantics is captured by handlers, which are functions that transform syntax trees

Algebraic effect handlers are a powerful means for describing effectful computations. They provide a lightweight and orthogonal technique to define and compose the syntax and semantics of different effects. The semantics is captured by handlers, which are functions that transform syntax trees

. We resolve both of these issues in this paper. We derive a solution that is both lightweight and principled. We do so by starting from a functional specification of Prolog based on monads, and extend this with the effect handlers approach to capture the dynamic search tree as syntax. Effect handlers

We design and implement a library that solves the long-standing problem of combining effects without imposing restrictions on their interactions (such as static ordering). Effects arise from interactions between a client and an effect handler (interpreter); interactions may vary throughout

the pipe need not be re-fetched and re-executed; and (2) any instructions that are independent of the exceptional instruction can continue to exe-cute in parallel with the handler code. In effect, doing so provides us with lockup-free TLBs. We simulate a lockup-free data-TLB facility on a processor model

-chains across appli-cation processes. Scippa provides provenance information required to effectively prevent recent attacks such as confused deputy attacks. Our solution constitutes a system-centric ap-proach that extends the Binder kernel module and Android’s message handlers. Scippa integrates seamlessly

Tracker soft-ware system is presented. The system is shown effective through multiple proxy deploy-

, and Servilla. Limone reliably handles high levels of dynamics within MANETs. It does this through lightweight coordination primitives that make minimal assumptions about network connectivity. Agilla enables self-adaptive WSN applications via the integration of mobile agent and tuple space programming models
