I have a long-running Raspberry Pi camera project to capture images of the view from a window (more details here). A recent post on mastodon, which showed a keogram, encouraged me to take my PiCam images and turn them into art. The finished product This is the finished wall art, printed on canvas. Ready to […]

Papers for MD9A8 – 2023 edition
It’s a New Year and so it is time to post the papers I have selected for a module that I teach on (MD9A8, the module formerly known as MD997). Previous selections are grouped here or here. The list serves as a snapshot of interesting papers published in the previous 12 months or so. I hope it […]
Over and Over: quick ways to reuse handy shell one-liners
There are a few one-liners that I use in the shell to do some really nifty stuff. I struggle to quickly find and reuse these and asked for a solution on Mastodon. A handy one-liner might be something like (taken from here): This converts all the flac files in subfolders into mp3 files. Obviously, we […]
Running Around: 2022 running dataviz in R
2022 was my best year for running to date. In 2021, my goal was to run 2021 km. For 2022, I wanted to see if I could run 2500 km and also to run 50 HM-or-more distance runs. I managed both and ended the year on a total of 2734 km. I also bagged two […]
Twitcher II: tweet frequency and top tweets
Another post looking at Twitter data in R. It follows this one and this one. I wanted to look again at my tweeting frequency over the 12 years on Twitter, but this time do it in a calendar view. Something like a GitHub commit calendar would be perfect. I have used a library for this […]
Now Playing
Another post about my time on Twitter. I will post the code in a separate post so that the R-bloggers don’t syndicate this one, which is about music. In my time on Twitter I occasionally posted about what I was listening to. I did this with a #NowPlaying hashtag. I wanted to preserve these tweets […]
Any Time At All: tweet frequency around the clock
Please consider this a “supplementary analysis” to my previous post looking at the frequency of tweets from my personal account over the last 12 years. I was curious about what times I was active on Twitter (measured by when I tweeted). Others might be interested in a solution to look at this in R. The […]
Twitcher: tweet frequency over the years
At the time of writing, I have essentially left Twitter. It was a fun ride and without going into what’s happening there now, this is a good opportunity to look at my 12 years on the platform. Early in November, I downloaded my data and locked my Twitter account. This gave me all the data […]
Free Bird: moving to Mastodon
There’s plenty of guides to getting going on Mastodon, aimed at people leaving Twitter. I just wanted to post a couple of technical points about making the switch that might be of interest to people who maintain webpages with Twitter content (feeds, embeds). Mastodon status updates (feed/timeline) Twitter provided a widget that meant that an […]
Form and File: estimating running form in R
There are lots of ways for runners and cyclists to analyse training data. A key question most fitness enthusiasts want to know is “how am I doing?”. “How you are doing” is referred to as form. Unsurprisingly, form can be estimated in many ways. One method is using training stress scores (acute training load and […]
