Our thoughts on technology and design

Testing
I have written about something that I found very interesting, Cognitive intelligence. My blog will contain information about cognitive intelligence,the benefits of testing with cognitive tools, what sectors currently use this, available platforms and finally if cognitive intelligence will take over a tester’s role.

How many times have you heard that from a client? Usually, a sponsor, or a traditional project manager embarks on a tirade: “Back in the day, we would use ideal engineering man-days as a benchmark. Then the work would be estimated in hours, which would then be fit into ideal...

Machine learning (ML) has become an increasingly popular field of Computer Science. In the past few years I've found myself working with ML to categorise large sets of data, and Scikit Learn for Python has proved itself to be exceptionally good for the task. This post walks through a simple example of Scikit Learn to categorise handwritten digits.
UX Design
Last week, designers from across the globe gathered for the annual Interaction conference. Here are some of my thoughts and takeaways from the event.

Conflicts sometimes arise when merging two npm-shrinkwrap.json files from different source control branches. Git might be able to solve some of these - but should you let it, and what should you do if it can't?

With an objective of building some docker images on cloud CI infrastructure I introduce one build-template sledgehammer I've been using recently, multi-stage docker builds running in docker-in-docker host container, with examples of AWS CodeBuild and Gitlab CI, and musing on other options.
Testing
Taking the time upfront to consider the focus of your testing can pay dividends. It shouldn’t just be a priority to test early to decrease the cost of fixing issues, it should also be a priority to test in the right way from the start, to ensure we are meeting the needs of our users.

In highly-visual, rapidly-updating, multi-window, buzzword-laden apps performance is a big concern. With WebWorkers, SharedWorkers and ServiceWorkers we have a number of options for moving complex scripting tasks off the critical path. However, rendering can be more of a dark art. In this post I'll dig into how one browser (Chromium) uses renderer processes and how you can use this knowledge to your advantage.

Java Optional has been around for a while now. It is a pity that this language feature is not used more often by developers. This is a simple demonstration of how to use it correctly.

A discussion of how companies develop rules in line with the values they hold, and how to deal with situations where those rules obstruct you from your job.
Data Engineering
In this quick look at the R language and tools I'll look briefly at the syntax of the language and have a go at creating a few charts with a data set.

First introduced to me as “upside-down recursion”, dynamic programming is a technique used to write efficient algorithms to solve a wide range of problems, often replacing recursive approaches. Having met many examples in the past few years, this post explores three applications I’ve seen for the benefit of those new to the technique.

A quick look at Apache Storm with a short word count walk-through example using a Redis Database.

If you're a fan of Redux Saga then you will have noticed the abundance of libraries to assist testing your sagas. This post takes an in-depth look into the different approaches to testing sagas, describing where five popular testing libraries fit into these approaches.

In this post, I create an interactive map of relative changes in currency strength, using D3's geographic projections, world map data, and a currency exchange API.

Being software developer requires technical insight and analytical approach. Yet, this is just part of the role. This article explores soft skills that are important part of every software developers life.

I show a simple use of the PostGIS Postgres database extension to combine route data from Strava and postcode data.

The focus of this article is not on finding advantages or disadvantages of Selenium WebDriver, but I mainly focus on investigating pros and cons of different tools/frameworks in combination with Selenium WebDriver. Thus this article is good for those who already know Selenium and would like to gain knowledge of using different tools in combination with Selenium.

In our professional work life we regularly come across difficult people we’d love to avoid, ignore or get away from - this is especially true if you are a consultant or contractor and work with so many different people. In reality however, we have to collaborate also with difficult people. In this article I want to look at the situations, types of people and some techniques that can help.

AWS recently announced a couple of new container services, EKS and Fargate, and I'll give a brief overview, a "first experience" walkthrough of Fargate, and discuss when you might want to choose it.
