[Links of the Day] 26/04/2017 : Aphyr Scala Day, Sia blockchain file storage , How brains are built

• Aphyr Scala Day 17 : Aphyr breaks database for a living and then talks about it :) 
• Sia : a Blockchain-based marketplace for file storage, the really attractive thing is the cost comparison of SIA vs public cloud system. Which is between a tenth to a hundredth time cheaper than S3 or other similar solution. I would be curious to see the performance thought.
• How brains are built: High-level overview of principles of computational neuroscience.
