wAIred_RabobankIgniteSession_12062025.pptxSimonedeGijt In today's world, artificial intelligence (AI) is transforming the way we learn.
This talk will explore how we can use AI tools to enhance our learning experiences, by looking at some (recent) research that has been done on the matter.
But as we embrace these new technologies, we must also ask ourselves:
Are we becoming less capable of thinking for ourselves?
Do these tools make us smarter, or do they risk dulling our critical thinking skills?
This talk will encourage us to think critically about the role of AI in our education. Together, we will discover how to use AI to support our learning journey while still developing our ability to think critically.

Async-ronizing Success at Wix - Patterns for Seamless Microservices - Devoxx ...
Async-ronizing Success at Wix - Patterns for Seamless Microservices - Devoxx ...Natan Silnitsky In a world where speed, resilience, and fault tolerance define success, Wix leverages Kafka to power asynchronous programming across 4,000 microservices. This talk explores four key patterns that boost developer velocity while solving common challenges with scalable, efficient, and reliable solutions:
1. Integration Events: Shift from synchronous calls to pre-fetching to reduce query latency and improve user experience.
2. Task Queue: Offload non-critical tasks like notifications to streamline request flows.
3. Task Scheduler: Enable precise, fault-tolerant delayed or recurring workflows with robust scheduling.
4. Iterator for Long-running Jobs: Process extensive workloads via chunked execution, optimizing scalability and resilience.
For each pattern, we’ll discuss benefits, challenges, and how we mitigate drawbacks to create practical solutions
This session offers actionable insights for developers and architects tackling distributed systems, helping refine microservices and adopting Kafka-driven async excellence.

On-Device AI: Is It Time to Go All-In, or Do We Still Need the Cloud?
On-Device AI: Is It Time to Go All-In, or Do We Still Need the Cloud?Hassan Abid As mobile hardware becomes more powerful, the promise of running advanced AI directly on-device is closer than ever. With Google’s latest on-device model Gemini Nano, accessible through the new ML Kit GenAI APIs and AI Edge SDK, alongside the open-source Gemma-3n models, developers can now integrate lightweight, multimodal intelligence that works even without an internet connection. But does this mean we no longer need cloud-based AI? This session explores the practical trade-offs between on-device and cloud AI for mobile apps.
Integrating Survey123 and R&H Data Using FME
Integrating Survey123 and R&H Data Using FMESafe Software West Virginia Department of Transportation (WVDOT) actively engages in several field data collection initiatives using Collector and Survey 123. A critical component for effective asset management and enhanced analytical capabilities is the integration of Geographic Information System (GIS) data with Linear Referencing System (LRS) data. Currently, RouteID and Measures are not captured in Survey 123. However, we can bridge this gap through FME Flow automation. When a survey is submitted through Survey 123 for ArcGIS Portal (10.8.1), it triggers FME Flow automation. This process uses a customized workbench that interacts with a modified version of Esri's Geometry to Measure API. The result is a JSON response that includes RouteID and Measures, which are then applied to the feature service record.
