Walking to work

July 21st, 2023

My commute changed a few weeks ago – from a short drive, to a cross-country walk. I had to return my company car as we don’t do them any more, and I chose not to replace it. So now I’m starting and ending my day with a walk.

What can you do with IBM Event Automation?

July 9th, 2023

This is IBM Event Automation : a new product we released last month to help our clients create event driven solutions.

I’ve written a 200-word summary of what IBM Event Automation is, but in this post I wanted to dive a little bit deeper and show what it can do.

Machine Learning for Kids with EduBlocks

July 8th, 2023

Students can now create Machine Learning for Kids projects using EduBlocks – letting them create machine learning Python projects in the browser by dragging and dropping blocks on a canvas.

This is all thanks to a fantastic new contribution from Joshua Lowe.

Here’s a quick run-through to show what this makes possible.

What is IBM Event Automation?

July 4th, 2023

A summary of IBM Event Automation in under 200 words.

Last week was the first release of IBM Event Automation. I’ve been asked what it’s all about, so I thought it’d be helpful to have a brief summary to point people at.

IBM Event Automation is a collection of three components, designed to help companies be productive in creating event-driven solutions.

What children can learn about artificial intelligence

May 21st, 2023

One of the conference presentations I gave last year was a talk at Heapcon, sharing some stories of AI/ML lessons I’ve run in schools. The focus of the talk was how I’ve seen children understand and react to machine learning technologies.

I’ve since expanded the ideas in this talk into a mini-book at but here is a recording of where some of these stories started.

Using Xbox to get started with Kafka Connect & Kafka Streams

May 17th, 2023

It’s easy for developers who aren’t immersed in all-things-Kafka to assume that “Apache Kafka” just means an event backbone: something that hosts topics (and perhaps the client libraries to produce and consume messages using those topics). But Kafka is more than that. It is an ecosystem of tools that enables a complete event-streaming application.

That was the premise of this talk, recorded at Devoxx UK, which I gave to a room of Java developers. I introduced them to two other bits of Kafka: Kafka Connect (for getting data in and out of Kafka topics from external systems) and Kafka Streams (for developing stream processing applications).

Because they were Java developers, I thought the best way to give them a flavour of these tools was to show them the APIs, and walk through an example solution made using the APIs.

The example solution used Kafka tools to process data from Xbox – mostly because I’m a gamer and it made for a fun, if silly, demo.
