Presentation: From VR to Flat Screens: Bridging the Input and Immersion Gap

Dany Lepage — Thu, 16 Apr 2026 14:10:00 GMT

Dany Lepage discusses the architectural journey of porting a hit VR title to seven non-VR platforms. He explains how his team solved the challenges of cross-progression, diverse input paradigms, and maintaining release velocity across Steam, iOS, and PlayStation. Beyond the tech, he shares candid lessons on the "product fit" gap when translating immersive social presence to 2D screens.

Presentation: Platform Engineering: Lessons from the Rise and Fall of eBay Velocity

Randy Shoup — Tue, 14 Apr 2026 11:17:00 GMT

Randy Shoup discusses the "Velocity Initiative," a transformation that doubled engineering productivity and modernized eBay’s DORA metrics. He shares the technical playbook used to scale 4,500 services while explaining why even elite engineering execution can’t save a company hampered by waterfall planning, risk aversion, and a "pathological" culture of fear.

Presentation: Reimagining Platform Engagement with Graph Neural Networks

Mariia Bulycheva — Mon, 13 Apr 2026 13:23:00 GMT

Mariia Bulycheva discusses the transition from classic deep learning to GNNs for Zalando's landing page. She explains the complexities of converting user logs into heterogeneous graphs, the "message passing" training process, and the technical pitfalls of graph data leakage. She shares how a hybrid architecture solved inference latency, delivering contextual embeddings to a downstream model.

Presentation: Latency: the Race to Zero...Are We There Yet?

Amir Langer — Fri, 10 Apr 2026 14:28:00 GMT

Amir Langer discusses the evolution of latency reduction, from the Pony Express to modern hardware. He explains how separation of concerns - decoupling business logic from I/O - and tools like Aeron and the Disruptor achieve single-digit microsecond speeds. He shares insights into replicated state machines, consensus protocols like Raft, and the future of low-latency sequencer architectures.
