Domain Driven Design

Modern Microsoft Fabric projects often start with built‑in Git integration and deployment pipelines—but at enterprise scale, those capabilities alone are rarely sufficient. As environments grow in size and complexity teams need more advanced tools and patterns to manage Fabric artifacts reliably across development, test, and production. In this session, we will: \- Review common enterprise lifecycle challenges in Microsoft Fabric \- Introduce advanced DevOps tooling and automation patterns used to address them \- Walk through a realistic implementation pattern that shows how these tools fit together in practice This session is designed for data and platform engineers and architects responsible for operating Microsoft Fabric in production. If you’re already using Git integration and deployment pipelines and are looking to extend them with more scalable, repeatable, and enterprise‑ready CI/CD practices, this session will help you understand when and how to go beyond the defaults. *Come at 5:30 pm have some pizza and chat for a bit. The presentation starts at 6:00 pm.*

**This is a ticketed event. Please register at [this link](https://luma.com/wbpv7ouu).** In this talk, Talha Paracha will present insights from his latest research on using language models for improving software security ("Hallucinating Certificates", to appear at ICSE 2026). Certificate validation is a crucial step in Transport Layer Security (TLS), the de facto standard network security protocol. Prior research has shown that differentially testing TLS implementations with synthetic certificates can reveal critical security issues, such as accidentally accepting untrusted certificates. Paracha et al. introduce a new approach, MLCerts, to generate synthetic certificates that leverages generative language models to more extensively test software implementations. Recently, these models have become (in)famous for their applications in generating content, writing code, and conversing with users, as well as for "hallucinating" syntactically correct yet semantically nonsensical output. The authors leverage two novel insights in their work: (a) TLS certificates can be expressed in natural-like language, namely in the X.509 standard that aids human readability, and (b) differential testing can benefit from hallucinated malformed test cases. MLCerts finds significantly more distinct discrepancies between the five TLS implementations OpenSSL, LibreSSL, GnuTLS, MbedTLS, and MatrixSSL than the state-of-the-art benchmark Transcert. ​​​**Event Schedule** 6:00 to 6:30 - Food and introductions 6:30 to 7:30 - Presentation and Q&A 7:30 to 9:00 - Open Discussions ​​​​​​If you can't make it in person, feel free to join the live stream starting at 6:30 pm, via [this link](https://www.youtube.com/@Trajectory-Labs/live).

Let’s do some coding together at a cafe! No more working alone in the weekend. Here, we write code together. And I mean together together. Not occupying-the-same-space-but-separate together. Here’s how it works: Jennifer brings her mobile app project, tells everyone that it is like Pinterest for recipes and she’d like to work on the nav bar. Paul and Chloe think Jennifer's project is fascinating, and they join the group. They gather around Jennifer’s laptop and work on the nav bar for 2 hours. Jennifer is the one typing out the code while Paul and Chloe research, brainstorm, and offer suggestions. If you’re feeling stuck on your own project or need a motivation boost, bring it to mob programming! Want to learn by watching how others code and solve problems? Join someone else’s project at this event! Oh and we love your half-done projects that you are a bit embarrassed to share. Absolutely bring those to the event! **Discord**: We use Discord to share screen & code snippets during the event. Also feel free to share your projects here before the event! https://discord.gg/yvAGbh4PpD **Event policy**: * We have 0 tolerance for harassment. * We don’t allow the projects that are not meant to be shared in public such as school assignments, interview tasks, or trade secrets. * The goal is to write code. We discourage you from pitching business ideas here, doing code reviews, or spending the whole event on planning what to do. * Please buy a drink, and tip the barista well.

Hi everyone!! 💖 So excited for our second book club meetup!

Don’t stress if you’re new or didn’t make it to the first meetup! This is a super chill group and we’re mostly here to chat, vibe, and obsess over books together. Can’t wait to see you all!! 📚✨

A diffuse harm hurts many people a little; a concentrated harm hurts one person a lot. Other things equal, diffuse harm seems less bad than its concentrated counterpart. For example, shortening a billion happy lives by a second each seems less bad than shortening one happy life by a billion seconds (\~30 years). But this attractive thought is surprisingly difficult to maintain. Although many problems for such a view are known, a particularly vivid difficulty arises in cases that involve a sequence of social positions, each very similar to the last, such as the Fortuna’s Wheel scenario. In such cases, it follows, from rather minimal assumptions, that diffuse harm is just as bad as its relevantly similar concentrated counterpart. In response, some may wonder whether the parity of diffuse and concentrated harms holds only in these special sequential cases. But it can be argued that the approximate parity of diffuse and concentrated harms extends well beyond such cases. Specifically, it can be argued that in many realistic cases, a diffuse harm will bring about an outcome approximately as bad as a relevantly similar concentrated harm. Diffuse harm is easily underestimated.

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

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
