## Details 18:00 - Mingling 🎉, SWAG 🎁, pizza 🍕, and beers 🍻 18:30 - 19:45 Lecturers 19:45 - IntelliJ Licenses + Node.TLV 20025 ticket 🎉 (more details in [https://www.nodetlv.com/)](https://www.nodetlv.com/)) ## Full Agenda From: Tal Doron : [Hebrew] **Querying for Evil: Using BigQuery to Find Threats in the SMB realm** This session dives into our practical approach for transforming massive volumes of cloud productivity logs into actionable security intelligence. We'll demonstrate how we leverage Google BigQuery as a highly-scalable data warehouse to store, process, and analyze this data at speed. You'll see how we execute complex, high-performance queries that uncover subtle anomalies, hunt for advanced threats, and provide critical detections to secure our customers. From [Anatol Zakrividoroga](https://www.linkedin.com/in/anatol-zak/overlay/about-this-profile/): [English] **Full-Stack Type Safety Without the Boilerplate: Meet tRPC** Keeping your frontend and backend in sync is hard — especially when API contracts drift, types get out of date, and your IDE stops being helpful. tRPC solves that by letting your backend define procedures that your frontend can call directly, with full TypeScript inference from end to end. In this talk, we’ll explore how tRPC eliminates unnecessary schemas and code generation while still delivering robust, type-safe communication between client and server. You’ll see how to set up a fully type-safe full-stack workflow, catch breaking changes before they hit production, and dramatically reduce the overhead of maintaining APIs. From: [‫Sagi Carmel](https://www.linkedin.com/in/sagicarmel/overlay/about-this-profile/): [Hebrew] **Promise you will learn something new about promises** Most of the time we are using Promises without reeeally understanding it's practical use v.s. what it was before. We will learn in a very interactive lesson the pure basic.
