A Deep Dive into PostGIS Nearest Neighbor Search

In this post, we’re going to take a deeper dive into the Postgres and PostGIS internals to find out how this actually works. By the time we surface you will have a better understanding of the advanced technical capabilities and unparalleled extensibility of Postgres. You’ll also appreciate how the open philosophy of Postgres has fostered a development community whose collaboration over many years has provided powerful features that benefit numerous users.

Testing sync at Dropbox

Executing a full rewrite of the Dropbox sync engine was pretty daunting. (Read more about our goals and how we made the decision in our previous post here.) Doing so meant taking the engine that powers Dropbox on hundreds of millions of user’s machines and swapping it out mid-flight.

Introducing PodTopologySpread

Managing Pods distribution across a cluster is hard. The well-known Kubernetes features for Pod affinity and anti-affinity, allow some control of Pod placement in different topologies. However, these features only resolve part of Pods distribution use cases: either place unlimited Pods to a single topology, or disallow two Pods to co-locate in the same topology.

A state-of-the-art open source chatbot

Facebook AI has built and open-sourced Blender, the largest-ever open-domain chatbot. It outperforms others in terms of engagement and also feels more human, according to human evaluators. The culmination of years of research in conversational AI, this is the first chatbot to blend a diverse set of conversational skills — including empathy, knowledge, and personality — together in one system.

Google’s medical AI was super accurate in a lab. Real life was a different story.
