ACCU York [September 2026] - Looking at that pages of computing systems

🕡 Doors open 18:30
📋 Intro and admin 18:50
🗣️ Talk by Opeyemi Folorunsho (🕖 start at 19:00)
In computing, few words are as deceptively simple as "page." We page memory. We flush dirty pages to disk. We traverse B-tree pages. We paginate APIs. We build web pages. The same word appears across hardware, operating systems, databases, distributed systems, and user interfaces, yet it rarely means the same thing twice.

This talk traces the evolution of "page" from its origins in virtual memory to its role in storage engines, buffer pools, write-ahead logs, and modern web architectures. Along the way, we examine how page size encodes hardware assumptions, how page boundaries influence performance and consistency, and how pagination shapes human interaction with data.

By connecting memory pages, disk pages, database pages, web pages, and API pages into a unified mental model, we reveal a deeper systems insight: a page is not merely a data structure, it is a boundary. And boundaries define isolation, locality, latency, and scale.

Attendees will leave with a clearer understanding of how a single abstraction quietly shapes performance engineering decisions across the entire computing stack.

🔗 Finish off with Q&A, networking, and 🍻

About the speaker: Opeyemi Folorunsho
Opeyemi Folorunsho is a software engineer and technology leader specializing in distributed systems, data infrastructure, and high-performance financial platforms. As Vice President of Research and Development at Moniepoint, he leads initiatives focused on scalable transaction processing, ledger systems, and platform engineering across cloud and multi-cluster environments.

His work spans database internals, consensus systems, storage engines, and large-scale event streaming architectures. He is particularly interested in how theoretical foundations such as information theory, concurrency control, and queueing theory map directly to real-world system performance.

Opeyemi is passionate about building systems that are not only scalable, but deeply understood, guided by the principle: "What I cannot create, I do not understand."
