Adopting Memory-Safety and Fine-Grained Compartmentalisation with CHERI

David Chisnall discusses how the CHERI hardware architecture redefines pointer safety to solve isolation and sharing challenges. He explains how CHERI enables spatial and temporal memory safety for C/C++, scales down to microcontrollers with CHERIoT, and replaces costly OS-level RPC mechanisms with lightweight, auditable compartmentalization - all without requiring massive codebase rewrites.

Comprehension as an Architectural Characteristic: A System That Is Not Understood Cannot Evolve Safely

As AI commoditizes code output, system comprehension silently decays, creating cognitive debt that threatens safe architectural evolution. This article explores why human understanding must be treated as an essential architectural characteristic, offering actionable strategies, socio-technical metrics, and design checkpoints to preserve intent across modern engineering teams.

Bio

Ralph Johnson is one of the four authors of the Design Patterns book. He is currently involved with the CS Department at the University of Illinois and the leader of UIUC Patterns/Software Architecture Group. He is mostly interested in OOP, especially frameworks, patterns, business objects, and Smalltalk, and researches refactoring being involved in creating the Smalltalk Refactoring Browser.

About the conference

Starting in 1986, OOPSLA Conference has proven to be the cradle of many techniques and methodologies that have become mainstream over the years: OOP, Patterns, AOP, XP, Unit Testing, UML, Wiki, and Refactoring. Gaining its prestige with 3 academic tracks, OOPSLA Conference has managed to attract researchers, educators and developers every year. The event is sponsored by ACM.
