Hashing and All that

This piece from Rice.edu is interesting.   It shows how the method of 'Hashing' can be used to reduce computations in deep learning neural networks.   This is probably understandable only to those with a degree or training in the details of Computer Science.   'Hashing' is a well known,  well understood technique in databases and cryptography.    How this is used for Deep Learning computation is fascinating.   Also covers a number of the issues that come up when you need to learn and retrieve learning in very large databases.  Worth reading.

A Cloud Intrusion

An example of a cloud security issue with the popular package Evernote, which I have used for some time.  Good example which led me to refresh my understanding of hashing and salting,  as applied to Password security.  And a reminder that security is always a compromise with convenience.
