Learn to Code

**Abstract:** This talk introduces a new high-level CUDA C++ library that brings functional, array-style programming to GPUs - without compromising performance. With a fluent API that slashes boilerplate and minimizes kernel launches, it enables you to write expressive, high-performance GPU code with up to 10× less code. This talk explores how functional patterns can unlock both clarity and speed in GPU development. **Speaker: Conor Hoekstra** Research Scientist at NVIDIA working on array programming models and languages. Creator of the [Parrot](https://nvlabs.github.io/parrot/) library (a high-level, array-based library with implicit GPU fusion). Extremely passionate about programming languages, algorithms, and beautiful code. Founder and organizer of the [Programming Languages Virtual Meetup](https://www.meetup.com/Programming-Languages-Toronto-Meetup/). Host of four podcasts and an avid conference speaker.

For several decades, scientists worldwide have described the impending future (and now, the present circumstance) as a “climate crisis” or a “climate emergency”. People now know that there is very little time to implement strategies to mitigate climate change before irreversible climate danger occurs. Given this, fear and despair seem like natural responses and motivators for action; we want to avoid, or at least mitigate, a future more apocalyptic than our present already is. However, hope might, alternatively, seem like a necessary tool for envisioning a safe and sustainable future as well, where climate justice is achieved. When it comes to the climate crisis, do you find yourself responding primarily with a sense of hope, or a sense of despair? Which of these responses do you see as being the more effective guiding sentiment when it comes to climate action? Join returning moderator Jasmine Tremblay D’Ettorre and Sophia Whicher at our next *Revisited* Curiosity Café, where we will explore the intricate relationship between these concepts in a discussion that is both thought-provoking and intriguing. We will explore the ethical – and emotional – dimensions of our responses to the climate crisis, so be ready to reflect, question, challenge, and expand your thinking! **Space is limited!** **Please obtain a “Pay-What-You-Can” ticket from Curiosity Café at [this link (click here)](https://www.eventbrite.ca/e/curiosity-cafe-revisited-hope-despair-and-climate-action-tickets-1987289833388) to attend this event. You need a ticket to be admitted.** See the above link for more info about tickets and other options including a limited number of free tickets. Come and hang out with us, grab food, and read through our handout from 6-6:30pm. Our structured discussion will run from 6:30-8:30pm with a 10 minute break in the middle. Hope to see you there! *Every four(ish) weeks, we revisit a previous Curiosity Café. In this series, we will be repeating topics, sometimes with a slight twist, sometimes with the same questions (but rest assured, even if you went to the first iteration and the questions were exactly the same, the discussion will change based on who is in attendance. Maybe you’ve even changed too…).* ***__________________________________________________________________*** This event is brought to you by [Being and Becoming](https://beingnbecoming.org/), a Toronto based non-profit. We aim to create community around exploring everyday concepts and experiences so that we may live more intentional, thoughtful, and meaningful lives. We use philosophy as a tool with which we can come to a richer understanding of the world around us. By offering activities, spaces, and other opportunities for conversation and co-exploration, we hope to enable the meeting and fusion of individuals and their ideas. Everyone is welcome, regardless of background: indeed, we believe the journey is best undertaken alongside explorers from a variety of disciplines, cultures, backgrounds, and experiences. Find out more about Being and Becoming [here](https://beingnbecoming.org/). About the Curiosity Café Series: For those of you who haven’t had the opportunity to join us at our Curiosity Cafés and are wondering what they’re all about: every two weeks, we invite members of our community to come out to the Madison Avenue Pub to engage in a collaborative exploration of our chosen topic. Through these events, we aim to build our community of people who like to think deeply about life’s big questions, and provide each other with some philosophical tools to dig deeper into whatever it is we are most curious about.

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/xwjDdVSw3E **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.

The playbook for AI agent integration is becoming predictable: build an MCP server, expose your APIs as tools, and define the rules in prompts. That approach works, but it often pushes workflow and guardrails into client-side logic, where they are harder to enforce and easier to bypass. This talk presents a different approach. HATEOAS (Hypermedia As The Engine Of Application State)—a largely overlooked part of REST—allows an API to describe allowed actions and constraints at runtime. That makes it a natural fit for agents, which need clear, machine-readable guidance about what they can safely do next. We’ll show this in action with MoneyMate, an AI agent that performs sensitive operations such as money transfers. Using the Spring HATEOAS project, the agent is guided entirely by the API rather than by hardcoded tools or fragile prompt logic. AI hype aside, this is ultimately a talk about architectural validation. For years, HATEOAS was the hill REST purists loved to die on—complete with finger-wagging about “doing REST correctly”—while everyone else quietly shipped simple JSON and moved on. It turns out the purists weren’t wrong—just 20 years early. Come see why that extra structure finally pays off when your client is an LLM. **About the venue** Free Times Cafe has bistro-style seating and a full food and drink menu. Please consider helping to support the venue by planning to have supper during the talk. **Speaker Bio** Adib Saikali is a distinguished engineer at Tanzu by Broadcom, focused on helping Tanzu’s largest customers design and build cloud native applications and platforms using Spring and Kubernetes.
