Way back in 2010, Paul Battley was blogging about device discrimination on the Internet. The new iPlayer service was using TLS certificates to ensure that only specific devices were able to stream media from the BBC's servers. That's a situation which continues over a decade later. If you watch iPlayer on your laptop, you're stuck…

I recently had cause to take a beginners course in R - a language I'm fairly familiar with. One of the other students had never used it before, so we were buddied up in order for me to show them the ropes. The first lesson of R is always the same. Read a CSV, manipulate…

Last year, I blogged about why I make my work calendar public. It is useful to have a public website where people can see if I'm free or busy. But the version I created relied on Google Calendar which, sadly, isn't that great. It doesn't look wonderful, especially on small screens, and is limited to…

Many text based conversations threads can be visualised as a tree. This is a follow-up to yesterday's blog post about Twitter conversation trees. Mailing list archives often use nested <ul> to show a conversation. That's fine, but has the major drawback of not being interactive. There's no way to collapse a branch of a tree…

It's quite popular to see high street shops names "Somesuch and Sons". Indeed, my grandparents ran "Eden & Sons" for many year. Much rarer is seeing "... & daughters". But, of course, the plural of anecdote is not data! The UK register of businesses - Companies House - has a pretty good search engine. Doing…

I'm hooking my solar panels up to Twitter! Installation Inverter Fronius provide a comprehensive API guide - I wish more companies did this. There are lots of unofficial libraries in a variety of different languages. I've written this code in Python3. This is a general tidy-up of the code I wrote several years ago. Here's…

I write book reviews on my blog. I also want to syndicate them to Goodreads. Sadly, Goodreads doesn't natively read the Schema.org markup I so carefully craft. So here's the scrap of code I use to syndicate my reviews. Goodreads API Keys Get your Keys from https://www.goodreads.com/api/keys You will also need to get OAuth tokens…

This is a quick and dirty way to turn a DOI (Digital Object Identifiers for academic papers) into an HTML & Microdata citation. I use this to power my Citations page. Schema.org is a Microdata standard which allows machines to read your HTML and create semantic relations between documents. Here's a minimum viable citation: <blockquote…

One of my favourite works of art is The Great Bear by Simon Patterson. At first glance, it appears to be a normal London Tube map. But look closer... Cool! But there is something about it which has always bothered me. Each Tube line represents a theme - therefore, a station at the intersection of…

Amazon encourages developers to use Flask-Ask - the handy Python library for working with Alexa. Sadly, the project has been abandoned. They no longer take pull requests, you can't raise bugs against it, and the documentation is incomplete. So this is how I solved an annoying problem - how to get the name of a…
