1.1 Billion Taxi Rides on kdb+/q & 4 Xeon Phi CPUs
kdb+/q is considered by its users to have good performance attributes. So this is something I wanted to try for myself, which turned out to give some interesting results. In this blog post I'll see how fast kdb+/q can query 1.1 billion taxi rides. I'll be using the same dataset I've used to benchmark Amazon Athena, BigQuery, Elasticsearch, EMR, MapD, PostgreSQL and Redshift. I've compiled a single-page summary of these benchmarks.

Prototyping Tools | Cooper
When deciding how to build your next prototype, the vast landscape of modern prototyping tools can be overwhelming. It’s easy to stick with the tools that you know for expedience sake, but a lot of great new tools are available and worth exploring.

Building off of our prior roadtest, we’ve updated and added to our assessment of some of today’s tools. We hope this resource will help fellow designers find a prototyping tool that works for their needs.

This is a living document. We will continue to add more tools and update existing ones.
