I had the chance to attend to NCraft 2015 that took place in Paris. All sessions were recorded and some of them have been published on the web site
Among the available videos, my favorites are:
- Hadi Hariri - The Silver Bullet Syndrome
- Phil Trelford - WRITE YOUR OWN COMPILER IN 24 HOURS
- Evelina Gabasova - MACHINE LEARNING THE F# WAY
