This article builds on the previous article, so if you are new to the terms coupling and cohesion as they apply to software, please look at that first. In this article I’m going to look at cohesion as it applies to methods (or functions, if that’s what you call such things). Specifically, I’m going to … Continue reading Modularisation – cohesion at many levels

Modularisation – coupling and cohesion
This is related to the second of the things requested by Jesper, which was encapsulation. Encapsulation is a tool to use when designing software. It’s a bit abstract, and I don’t think people always agree on what it means. To me, encapsulation is part of the bigger term modularisation, which doesn’t immediately help because it’s … Continue reading Modularisation – coupling and cohesion
Visualising music
I watched a YouTube video about how to play the guitar part for 50 Ways to Leave Your Lover by Paul Simon. It’s an excellent video, that breaks things into manageable chunks that gradually build into the full thing. The video reminded me of diminished chords, and sliding them up and down a guitar, which … Continue reading Visualising music
Trends in UK Coronavirus cases, hospitalisations and deaths
A friend asked a question to do with Coronavirus that I couldn’t answer but I thought I should. So I got some data, did some calculations on it, and then worked out how to display it. The question was: how bad were hospitalisations and deaths from Coronavirus (in the UK) when the daily reported Coronavirus … Continue reading Trends in UK Coronavirus cases, hospitalisations and deaths
Visualising wealth inequality using Lorenz curves
In this article I will do some analysis and visualisation of data on wealth inequality. The data is, slightly randomly, a combination of historical data from three towns in Suffolk from 1522, and the most recent data about Great Britain. I’ll go through the data a little, the analysis, the visualisations, and why I think … Continue reading Visualising wealth inequality using Lorenz curves
Sankey diagrams to explain Coronavirus and Covid19
There’s a kind of diagram, called a Sankey diagram, that can be used to show relationships between things. I will briefly introduce it, and then use one to illustrate Coronavirus and Covid19 in the UK. It will simplify things, but I hope will still help you get a better understanding of how the various numbers … Continue reading Sankey diagrams to explain Coronavirus and Covid19
Analysing flooding rivers
I live in a place that has a river flowing through it. Like in many places in the UK, we have had floods this week, which has been stressful for people whose homes and businesses have been affected. Fortunately, we were OK and no-one here was affected too badly. As a complement to the stress … Continue reading Analysing flooding rivers
GB roads with gaps
I was driving recently, and realised that I was near a road that appeared to have a large gap. By that I mean: road A joins road B and stops, but some distance further along B there’s a bit more road A. It’s as if A has been chopped into two by B, and the … Continue reading GB roads with gaps
Simulating how birds form flocks
This article is about using a computer to simulate how birds form into flocks. This probably also applies to fish forming shoals and dinosaurs moving and grouping together like they apparently did. There’s a static snapshot of this simulation below, and clicking on the picture will take you to a live version where you can … Continue reading Simulating how birds form flocks
Great British Place Names Made of Smaller Bits
I was driving recently and saw a sign for a place whose name was built up of two things joined together. That got me wondering about other places I’ve seen whose names were like that. So I found some data, downloaded it, played around with it, and this is the result. There’s no great point … Continue reading Great British Place Names Made of Smaller Bits
