In modern Java applications, distributed systems are everywhere, and so are failure modes. But how do you know when your cluster is fragile, or if it’s on the brink of breaking? This talk dives into practical observability and resiliency techniques for distributed Java environments. We’ll highlight key patterns, failure signals, and metrics that matter, backed by a live demo using Hazelcast, Chaos-mesh, Prometheus, and Grafana. You’ll learn: Core Patterns – Leader election, partitioning, replication Metrics That Matter – Backup count, member count, JVM health, Golden Signals Failure-Aware Design – Resilience patterns, chaos testing principles Live Demo – Deploy a working cluster, simulate node failure, and explore metrics to observe how data integrity holds as the system nears its fault tolerance threshold Ideal for Java developers, architects, and SREs, this session blends theory, tools, and real-world failure scenarios to help you build distributed systems that stay online—even when things go wrong. **About the venue** Free Times Cafe has bistro-style seating and a full food and drink menu.

The public sphere is currently dominated by a handful of social media platforms — for example, X, Instagram, TikTok, YouTube, and Reddit — all built on centralized networks. Centralized networks concentrate decision-making and infrastructure in a single entity that manages user identity, data storage, policy enforcement, and content curation. This concentration of control grants platforms enormous power over online communication and public discourse. Yet these platforms are operated by unelected actors accountable primarily to shareholders rather than the public. I argue that operators of platforms built on centralized networks can’t legitimately exercise power over the public sphere. By contrast, platforms built on decentralized networks — which distribute control over identity, data, and policy across independent nodes interoperating through open protocols — can in principle exercise their power legitimately. The upshot is that legitimate platform governance requires migrating to decentralized architectures. Chris Howard https://www.mcgill.ca/philosophy/chris-howard Associate Professor Department of Philosophy McGill University About the Speaker: I'm an Associate Professor of Philosophy at [McGill University](https://www.mcgill.ca/philosophy/), where i direct the [Philosophy, Technology, & Policy Lab](https://www.mcgillptplab.com/). My earlier work was in normative ethics & metaethics. Now I work on questions about power, legitimacy, & governance in digital infrastructure. I'm focused on the illegitimate power of centralized social media platforms & AI systems, & on the prospects for legitimate decentralized alternatives. Before joining McGill, I was a research assistant professor at [UNC-Chapel Hill](https://philosophy.unc.edu/) & core faculty in the [UNC/Duke program in philosophy, politics, & economics](https://ppe.unc.edu/). **\* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \*** This is a talk with audience Q&A presented by the University of Toronto's Centre for Ethics that is free to attend and open to the public. The talk will also be streamed online with live chat [here](https://www.youtube.com/live/NGJrCWCnkyY). About the Centre for Ethics (http://ethics.utoronto.ca): The Centre for Ethics is an interdisciplinary centre aimed at advancing research and teaching in the field of ethics, broadly defined. The Centre seeks to bring together the theoretical and practical knowledge of diverse scholars, students, public servants and social leaders in order to increase understanding of the ethical dimensions of individual, social, and political life. In pursuit of its interdisciplinary mission, the Centre fosters lines of inquiry such as (1) foundations of ethics, which encompasses the history of ethics and core concepts in the philosophical study of ethics; (2) ethics in action, which relates theory to practice in key domains of social life, including bioethics, business ethics, and ethics in the public sphere; and (3) ethics in translation, which draws upon the rich multiculturalism of the City of Toronto and addresses the ethics of multicultural societies, ethical discourse across religious and cultural boundaries, and the ethics of international society. The Ethics of A.I. Lab at the Centre For Ethics recently appeared on a list of 10 organizations leading the way in ethical A.I.: https://ocean.sagepub.com/blog/10-organizations-leading-the-way-in-ethical-ai
