Test metrics have for too long been the 'Holy Grail' of determining quality. This blog post looks at the reason why the metric of 'defect density' should perhaps have a second thought before use to determine software and tester quality.
An insight into the ELK stack and how we used it on a big data project
Body as interface is plausible either when the body is in a controlled environment or when the device becomes part of the body. Exploring this notion allows us to stop designing interfaces and start designing experiences.
For the past few weeks, Laurie Collingwood and myself have been working on a prototype banking app with an animated graph. In this post we’ll discuss some of what we’ve learned during the project and talk generally about animation with HTML5 canvas. Designed...
Being a software developer requires constantly improving ones knowledge. This is a short list of books that made the largest impact on me as Java developer. I hope that you too will find here something that will take you to the next level!
We have recently been working on concept designs for a banking app aimed at the new generation of bank users. The main screen of one of such concepts hinges on a seamless transition between different views to communicate the relationship in the underlying data. While we often work with smaller,...
The redux pattern provides a simple (and strict) pattern for managing state; a single store holds the state while a reducer applies actions, evolving the application state. As your app becomes more complex, you can split up your reducer into separate functions, however, what if you have multiple instances...
Conversational Commerce drastically re-imagines the way services are delivered to customers by moving interactions with them into chat, messaging or other natural language interfaces such as voice. The following video captures some of our initial thoughts on how this might apply to financial services.
The size of things is relative to the scale that we set. This might sound like a trivial notion, but it is key to creating meaningful data visualisations.
In this post, we discuss design and implementation choices for account and session management features, and how these trade off against usability and other goals.
This is part 2 of the Using WebdriverIO guide where we'll be taking a closer look at the tests and implementing the page-object model.
WebdriverIO is a great addition to your automation toolkit. This 2-part post first walks through configuring WebdriverIO and automating the test process using Gulp, before taking a look at the tests themselves and abstracting using the page-object model in part 2.
Inspired by Colin’s article on building an expenses app with the Mondo API, I wanted to create something to make use of the webhook API which fires in real-time (ish) whenever a transaction happens. In this post I’ll cover subscribing to the Mondo webhook, creating the glue code as...
Over the past several years there has been a lot of talk about cryptocurrencies, such as bitcoin, and the blockchain technology that underpins them. However it can be difficult to understand how the blockchain actually works in practice, and why it is such a clever method for currency exchange. Two...
Kotlin is the latest JVM-targeted language to see a 1.0.0 release. Having experimented with it for a short while I thought I would capture my experience and point out a few gotchas.
Mondo Bank has recently moved into public Beta, sending out 1,000 cards to trial customers each week. I received my Beta card a few days ago, and have been using it ever since. This blog post takes a quick look at the Mondo API and how I used it to automate expense claims!
Along with the modularisation of code, D3 version 4 also brings new support for canvas drawing, thanks to the d3-path package introduced in version 4. There are performance advantages to using canvas over svg for drawing complex charts (however canvas is not necessarily always better). You can...
Automation of user interactions in browsers can be difficult. Even more so when you have to hunt for elements in a single page application. How can we ensure reliable location of these and reduce flaky checking?
This post introduces a new feature of D3 version 4: the d3-path package. d3-path is an abstraction over SVG path creation which uses the canvas element’s Context2D interface. Previously creating path generation code involved a lot of concatenating SVG path commands like M0,0 or
