[Links of the day] 09/05/2016: OSS bio metric framework , Deep learning framework comparative study & dropbox magic pocket

• OpenBR : open source bio-metric framework, I can't wait for the first community driven mass recognition system to come out. No more secrets... 
• Inside the Magic Pocket :  really good case study and architecture behind the storage system design to replace AWS S3 after Dropbox moved out of AWS [HN discussion]
• Comparative Study of Deep Learning Software Frameworks : version 3 of the extensive study of deep learning framework. What is interesting is while tensor flow is deemed extremely versatile it seriously lag behind the other framework performance wise.
