htm.core and C#

In case you weren’t aware, htm.core now also provides a REST interface to it’s Network API. With this in place, it is possible to utilize the built-in encoders, Spatial Pooler and Temporal Memory from almost any programming language. In this post I briefly want to touch on how to use htm.core and C# together.


Before you can start playing around with the REST interface, you will need to have the example REST server running.

To do that, you can either

  • download the source and build it yourself. Once built, the server executable (rest_server) should

.NET for Apache Spark Docker Image available on GitHub

.NET for Apache Spark Docker Image available on GitHub

I am really honored by the fact, that a lot of people seem to use my .NET for Apache Spark docker image to explore how C# and Apache Spark can work together, for example.

Additionally, I am getting a lot of request lately, asking whether I would be willing to share the code for creating the images.

And finally, after tidying it up a bit (e.g. removing the experimental Windows support), it is now available on GitHub.

So thanks to everyone who made this image such a success and of course you are very welcome to … more

.NET for Apache Spark ForeachWriter & PostgreSQL

.NET for Apache Spark IForeachWriter implementation


A couple of months ago I’ve described how to transfer data from Apache Spark to PostgreSQL by creating a Spark ForeachWriter in Scala.

This time I will show how this can be done in C#, by creating a ForeachWriter for .NET for Apache Spark.

To create a custom ForeachWriter, one needs to provide an implementation of the IForeachWriter interface, which is supported from version 0.9.0 onward. I am going to use version 0.10.0 in this article, however.

Documentation of the C# Interface is provided within the related source code:

The example project I am … more
