Following on from making a simple particle simulation in Go, I decided to try and implement a simple set of web services too.
At the Agile North East Lightning Talks Competition I had 8 minutes to tell a room full of people how to help testers succeed.
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.
I downloaded an analysed the training data for 1,000 athlete who ran the London Marathon in 2016. From this data I've learnt that people put in ~30% less mileage than popular plans suggest, Sunday mornings are a firm favourite for long runs, and that Saturday morning parkruns are very popular!
StreamSets Data Collector (SDC) is an open source tool for stream-based extracting, transforming and loading large quantities of data. It provides an easy to use UI on top of the underlying processing power of YARN and Spark Streaming with a large number of installable integrations with source and destination systems....
This post looks at the pros and cons of some of the automated handoff tools available for designers to share style specs with developers.
My first thoughts and impressions of version 11 of Alteryx.
With the advent of the Internet of Things, the world of Big Data couldn't be more relevant. This post gives an overview of technologies that achieve processing at scale and in real time.
I recently downloaded run data for the 7,190 athletes who recorded their London Marathon on Strava, a popular platform for runners and cyclists. This blog post visualises and analyses the data in various interesting ways.
After 18 months testing FX trading software I decided to create and share a heuristic cheat sheet to help explore trading apps.
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.
