Our thoughts on technology and design

Artificial Intelligence
When we couldn't find a tool to meet our prompt engineering needs, we decided to create a universal tool that allows anyone to build their own – all within the familiar spreadsheet environment. An Excel add-in that lets you use OpenAI models in Excel formulas.

In this blog, we will be sharing our feedback on the free fast.ai course - that has been praised by many for its hands-on and top-down approach - along with a list of additional material that we found helpful in fully understanding the course.
Sustainability
The goal of this post is to introduce some tools and techniques you can use to figure out what's the most effective climate action you can take given your circumstances. I'll give some examples of ways you can use your skills as a software developer to help out with climate solutions.
Delivery
Here, Chris Ferguson discusses why the face of public sector technology should be able to implement timely, meaningful change – and how waste can guide you in the right direction.
Artificial Intelligence
Recently I’ve been learning about Neural Networks and how they work. In this blog post I write a simple introduction in to some of the core concepts of a basic layered neural network.

A brief look into building out a NextJS application which makes use WebAssembly to solve Advent Of Code puzzles in the browser.

Many of us love a good podcast so I reached out to our project team to see what they were listening to in the tech and sustainability space. Here are their recommendations
Artificial Intelligence
We’ve undertaken experiments to explore the impact of GenAI tools on developer productivity, revealing a 37% improvement in productivity (speed), however, this result is a misrepresentation of what it means to be productive as a developer. This article delves more deeply, beyond punchy metrics, to explore the overall experience of working with these entirely new tools. We discuss where these tools are most effective, the challenge of quality code, the learning curve and much more.
Artificial Intelligence
Developing LLM applications using Test-Driven Development principles can be expensive due to the incurred cost of every usage. In this post, we discussed how our attempt to tackle the inherit non-deterministic nature of LLMs increased our operational costs and the techniques we employed to minimise them.
Artificial Intelligence
An update on our Spy Logic project and its journey to open source.
Artificial Intelligence
In this post, we walk through the steps required to create your own DiffEdit pipeline, allowing you to use generative AI to edit parts of existing images.
Sustainability
An investigation of the methods available to measure energy consumption programmatically.
Artificial Intelligence
An introduction to the random forest machine learning model, an older, yet interesting approach based on decision trees.
Artificial Intelligence
The memory costs for LLM training are large but predictable.
Sustainability
If you do one thing to optimise cloud carbon footprint start with your choice of region. Consider the balance between cost, environmental, security and performance considerations when it comes to choosing a cloud region consciously.
Artificial Intelligence
In this post, I provide an overview of the capability models that are out there, summarise the distinct capabilities required for AI/ML projects, and make the case for what I believe to be the most important capability your organisation will require.
Open Source
As I was reading this year's State of Open Source in Finance report, I reflected on my time working in financial services and the ongoing struggle they had adopting and contributing to open source. In this blog I look at the report's findings, how things have (and have not) changed in FS and how larger organisations can foster an open source culture.
Testing
Imagine a new Restaurant opens down the road from you, and you’ve been invited to the opening night. There are no reviews yet, but you’re curious to try it out - In this blog, I aim to simplify testing terminology through a comparison to a real-world scenario.
Testing
In this blog, I will walk the reader through some simple statistical concepts to aid in testing AI. I hope it is accessible regardless of prior statistical knowledge.
Artificial Intelligence
In the light of OpenAI’s system outage, a ripple of unprepared AI powered systems crashed across the world. How can we best secure our LLM based applications against such occurrences?
