A collection of articles, tutorials and blog entries on various computer technical architecture, hardware and software.
This short How-To post is a companion post to How to Install a Distributed Apache Storm Cluster, and shows how to debug an Apache Zookeeper installation. The debugging methods presented below include starting Zookeeper manually, pinging the Zookeeper serv... read more
Primary and Secondary Performance Metrics If you are building a classifier then you must measure it’s classification performance. If you are building a robot to pick up an object, you have to measure its ability to pick up objects. Any AI technology... read more
Context Knowm Inc is a very small company in a field of giants, and because of this we face very difficult constraints above and beyond the (already extremely difficult) technical problems we are trying to solve. Our goal is to build an adaptive learning ... read more

When creating graphical user interfaces with Java, it is often useful to add charts to your Java application for visualizing data. In this tutorial, we show how to easily add charts to a Java Swing application using our open source Java charting library X... read more
Ever since Knowm Inc. first launched the BS-AF-W memristors, it became clear that we needed a low-cost programmable interface to make it easier for people to learn how memristors work. Memristors are strange. They are ‘born’, they live for awh... read more
In 2009, Biolek et al. published a paper showing an idealized memristor model for a newly publicized memristor created at HP labs. The paper can be downloaded here. The model is referred to in a fews ways: “The Ideal Memristor”, “The non... read more
