Small multiples repeat the same basic chart, typically with the same axes, to display different slices of a dataset. They are an excellent way of showing rich multi-dimensional data, without becoming a dense mess of lines. This post looks at how to implement small multiples with D3 and d3fc.
In this post we compare how Cassandra and MariaDB can be configured to operate in clusters and how this affects response time for queries. We found Cassandra to scale well and to be highly configurable. MariaDB can be used with Galera Cluster but it does not provide horizontal scaling. Also NDB can be used to scale MySQL but it was not as configurable as Cassandra.
Your store is the source of truth... as long as it makes sense. A concrete example integrating Redux with React Router
Docker 1.13 introduces a simple way of providing secrets to containers
We've been comparing Cassandra and MariaDB in single node setups, exploring the issues of each in terms of performance and ease of use from a development perspective. In this article we explore the issues at play in such a setup such as the differences in queries, speed of response and the features that seperate these two technologies.
How I used Go to create a web app that would help me practice violin scales.
Level-up the state is perhaps the most useful React pattern. Apply it to your dependencies and you can get many benefits, like better tests, flow control and idempotent routes.

Facilitating UX workshops can be challenging when ideating with non-designers who have not participated in a UX workshop and are sceptical about its value. In this post, I suggest four tips for achieving successful UX workshops and gaining the trust of the more sceptical participants.
When creating d3 visualisations it's common to want some form of responsive layout. However, SVG and canvas don't provide a native way to do this. Most examples found online either use fixed dimensions or resort to some form of manual layout to achieve the required effect. This post introduces an alternative approach using CSS and custom elements.
Fiddler's AutoResponder is a great tool to mock API Responses when you're testing front end logic. It's simple but provides some powerful testing options. This is a short post to show you how.
