Discovering less-known PostgreSQL v12 features

Version 12 of PostgreSQL is not exactly fresh out of the oven, as the first minor release was already announced. However, I think it’s fair to say that this version can be still considered fresh for most users, and surely only a small percentage of users has upgraded. So I think it makes sense to go over some new features.

The Matrix Calculus You Need For Deep Learning

This paper is an attempt to explain all the matrix calculus you need in order to understand the training of deep neural networks. We assume no math knowledge beyond what you learned in calculus 1, and provide links to help you refresh the necessary math where needed. Note that you do not need to understand this material before you start learning to train and use deep learning in practice; rather, this material is for those who are already familiar with the basics of neural networks, and wish to deepen their understanding of the underlying math.
