### Andreas Rossberg (MPI) : Wasm 2.0 and Beyond

WebAssembly (Wasm) is a virtual instruction set architecture designed for portability, performance, safety, and formal rigour. After its initial release, it has seen wide adoption across diverse ecosystems, such as the Web, edge computing, distributed computing, mobile, embedded systems, and others. Recently, release 2.0 of Wasm was published, which represents a step forward towards a […]

### Upcoming paper: Rewriting for monoidal closed categories at FSCD 2022

Rewriting for monoidal closed categories David Sprunger, Dan Ghica, Fabio Zanasi and Mario Alvarez-Picallo.  This paper develops a formal string diagram language for monoidal closed categories. Previous workhas shown that string diagrams for freely generated symmetric monoidal categories can be viewedas hypergraphs with interfaces, and the axioms of these categories can be realized by rewritingsystems. This work proposes […]

### Upcoming paper: The Theory of Call-by-Value Solvability at ICFP 2022

The Theory of Call-by-Value Solvability The denotational semantics of the untyped $\lambda$-calculus is a well developed field built around the concept of solvable terms, which are elegantly characterized in many different ways. In particular, unsolvable terms provide a consistent notion of meaningless term. The semantics of the untyped call-by-value lambda-calculus is instead still in its […]

### Upcoming paper in OOPSLA: Higher Level Effect Handlers in C++

High-Level Type-Safe Effect Handlers in C++ DAN GHICA, Huawei Research, UK SAM LINDLEY, The University of Edinburgh, UK MARCOS MAROÑAS BRAVO, Huawei Research, UK MACIEJ PIRÓG, Huawei Research, UK Effect handlers allow the programmer to implement computational effects, such as custom error handling, various forms of lightweight concurrency, and dynamic binding, inside the programming language.
