Don’t break up with Jupyter Notebooks. Just use Kedro too!

This article is suitable for anyone who has found themselves seduced by the ease of working with Jupyter Notebooks. Although it’s aimed at readers who are relatively new to data science, it applies equally to more experienced data scientists & engineers who are considering how to improve their daily workflow.

The convenience of a Jupyter Notebook combined with Kedro’s software best-practice

I’m going to run through the reasons why we fall in and out of love with Jupyter Notebooks, and describe how the open source Kedro framework can help you solve some of the problems that cause headaches and heartaches for so many data professionals. And there’s no breakup involved! …

Environmental, social, and governance (ESG) metrics measure the sustainability and societal impact of an investment in a company or business. Before committing to a company, investors want to know if there are any potential controversies brewing, or if the company shows particular leadership in an area of ESG, such as diversity in the workforce.

A new Python library for production-ready data pipelines

In this post, I will introduce Kedro, a new open source tool for data scientists and data engineers. After a brief description of what it is and why it is likely to become a standard part of every professional’s toolchain, I will describe how to use it in a tutorial that you should be able to complete in fifteen minutes. Strap in for a spaceflight to the future!

*Be* the change in your online community

If you hang out “below the line” in the comments section of newspapers, on Reddit, StackOverflow or similar forums, there’s a good chance you’ve seen unkindness on the Internet.

In technology, particularly, we rely upon getting answers to our questions from the online community. There are rarely books on Swizzy startup’s Esoteric API v0.9, or Funky Framework v2; if you want answers to a question or problem that you cannot find for yourself, you go online to discuss it. …

How will we offset the rapidly increasing power consumption of data centres? Hyperscale has plucked the low hanging fruit. What’s next? [CC BY-SA 3.0 (], from Wikimedia Commons

Pop quiz: Which organ of your body uses the most energy?

It’s the brain, of course.

Your brain uses up to 20 percent of all the calories you consume each day.

Maybe that explains why we’ve readily accepted that computers will use a huge amount of energy in processing, and emit so much heat that they also create a secondary power need to cool them down?

We are becoming increasingly aware of the amount of energy the data centres supporting our favourite social media sites, film & music streaming services and online shopping are using, and are expected to use in the future:

In this interview, I’m catching up with Barry Zane, Vice President at Cambridge Semantics. Barry is creator of AnzoGraph™, a native, massively parallel processing (MPP) distributed graph database. Barry has had quite a journey in database world. He served as Vice President of Technology of Netezza Corporation from 2000 to 2005, and was responsible for guiding all aspects of software architecture and implementation, from initial prototypes through volume shipments to leading telecommunications, retail and internet customers. Netezza was eventually sold to IBM, but prior to that, Barry had turned his attentions elsewhere to found another company, ParAccel, which eventually became…

The hybrid model of computer-human intelligence offers a way to build on our mutual strengths and deliver efficiency

My friends at GRAKN.AI recently published an interesting article lamenting that “machines should be able to outperform humans in many more tasks than they currently can, or at least that they should be able to make truly smart predictions.”

The article makes the point that AI has cracked one of the key attributes of human intelligence — learning — but still has some way to go with logical reasoning over a representation of knowledge.

How do we help artificial intelligence to reason? It is so innate to us that we don’t even know we are doing it.

Still from Jamiroquai’s “Virtual Insanity” from

In this article, I’m going to talk about how I perceive the mainstream consumer audience to have rejected virtual reality, and suggest that its child, augmented reality, may be the Slope of Enlightenment (of the Gartner Hype Cycle) that convinces us to buy in. While these are my views alone, towards the end of the piece, I’ve unearthed some data from software developers around the world who are working with AR and VR. Even if you don’t care about my views, you may find what they have to say interesting. …

The next generation of graph databases focus on speed and scalability

This article introduces some of the key concepts of graph databases and their use cases, and explains how speed and scalability are critical to the next generation of graph databases if they are to tackle enterprise-level use cases and deliver high-performance machine learning.

The NoSQL (“not only SQL”) space presents a number of different data models and database systems which can be more suitable than relational systems for particular types of data and use cases. Among these are graph databases, in which data is formed of a collection of nodes, the edges that connect them, and a set of properties…
