Accessibility is essential to provide a high-quality experience for all of your users. However, it can be easy for failures to slip into our applications. In this post, we'll look at the six most common accessibility problems and discuss why they matter and how they can be fixed.
Data Engineering
This blog is about tools that help address the challenge of testing systems which handle large data volumes. We’ll see why creating a large, realistic and valid test data set is hard, how test data generators can help, and compare some of those available.
Careers
If you're hiring developers you're always going to need a technical interview as part of the process. This post discusses what you should look for in this interview to find the best applicants.
UX Design
Recently, a whole range of tools have been introduced promising to fully automate visual design specs, so that designers never have to manually create specs again. But is it really that simple? Just like other forms of automation, there are pros and cons to these tools that are important to consider.

Those organisations who emerged stronger and more competitive from the 2008 global financial crisis are at it again. They have benefited significantly from past bold and decisive moves and now they are wasting no time adapting to the next version of the future. So what are the tenets of change this time?

Following the recent relaxation of Lockdown, and with reports circulating of further loosening, we can all start to look forward to something approaching normality. But what will constitute “normal” in the future, and what will this mean for the technology we use?

This blog post introduces the WebGL components which we recently added to D3FC, this suite of components make it easy to render charts with very large numbers of datapoints using D3. Throughout this post I'll describe the creation of the following visualisation, which displays 1 million books from the Hathi Trust library

Async iterators are a great language feature that make working with asynchronous streams of data a joy to use. We'll take a look at consuming an async iterator running in a Web Worker from the main thread and see how we can use a library called Comlink to abstract away the fact it's running in a different execution context.

Pulumi is one of a number of newer IaC solutions, providing developers with real code for defining their infrastructure resources and services. This post assumes some prior knowledge of IaC concepts and technologies, particular Terraform and Serverless, along with CircleCI

I’m not loving you, the way I wanted to
What I had to do, had to run from you

WebGL presents you with a blank canvas (literally!) and leaves you with what feels like an overwhelming set of decisions to make before you can render your idea on screen. This post introduces a quick reference guide to picking the right draw call for those trying to decipher the difference between drawArrays, drawElements and their oddly-ANGLE'd instanced equivalents.

In this post, I am discussing my exploratory journey into Power BI and how to connect it to Azure DevOps and Jira so we can create more advanced analytics such as Cycle Time scatter plots and Cumulative Flow Diagrams. It is the short step-by-step tutorial that I would have liked to find on my own hunt for information on the topic.
