I recently offered to help out my personal trainer by writing an application to keep track of the number of reps a member had performed within a set time period. I thought this would be a good opportunity to test out how important it is to keep the users involved in the development process. Here's how it … Continue reading Developing an MVP with rapid feedback cycles
I had another trip to Amsterdam this month to attend Dave Snowden's course: Cynefin and Sense-Making. I'll be making a series of posts about what I learnt. I'll start by comparing systems thinking and complexity thinking and by giving an introduction to the field of study that Dave is calling Anthro-Complexity. In systems thinking, analysis of … Continue reading Systems Thinking, Complexity Thinking and Anthro-Complexity
Earlier this week I had a discussion about the running time of an algorithm used to test a method. This got me thinking about one of my favourite areas of computer science - computational complexity. We can use complexity theory to split problems into classes. Understanding some of these classes can help us to recognise when … Continue reading Stop trying to solve hard problems!
This is the second of a series of posts covering what I learnt at Velocity Amsterdam 2015. During the second day, Mike Amundsen of CA Technologies shared his insights into the works of Melvin Conway. While Conway's Law may be well known, it is only stated as the thesis of his article "How do committees invent?". Mike showed that … Continue reading Velocity 2015, 2: System Design = Organisation Design
I was fortunate enough to attend Velocity in Amsterdam this year, which followed several major themes - one of which being security. This post was inspired by a presentation given by Alex Schoof entitled "Managing Secrets at Scale". Alex covered many areas, including how to control the use of secrets, how they can be made highly available … Continue reading Velocity 2015, 1: Keeping Secrets Secret
I found it impossible to find a segment of code which showed how to generate a secure key pair in the enclave with swift for iOS 9. So... here it is! // private key parameters let privateKeyParams: [String: AnyObject] = [ kSecAttrLabel as String: "privateLabel", kSecAttrIsPermanent as String: true, kSecAttrApplicationTag as String: … Continue reading Generating a Key Pair with iOS’s Secure Enclave in Swift
As part of a placement earlier this year, I was given two sets of functions to play with. The first set was implemented in both MATLAB and FORTRAN and formed a root-finding algorithm. The second was implemented in only MATLAB but promised shorter running times and greater accuracy. The task was to compare the two … Continue reading A perfect matching of complex roots
I thought I’d share a post about a problem we faced in the most recent project I worked on. The aim of the project was to calculate certain properties of fluids which were being forced through a jet. This involved processing terrabytes of data, most of which was redundant as we only cared about the … Continue reading Processing big data from small experiments
