I'm right about everything. My opinions are wholly rational and a product of logical analysis. Your opinions are scattered thoughts and half-remembered fairy-tales. That's how most of us think, right? The only way we can get through the day is by thinking we're correct. I want to examine some of the things I think I'm…

My friend, the superhero Jess Rose, posed an interesting question. So, something lovely. About 6 months ago now @jesslynnrose tweeted the question “are you giving your interview questions to the candidate in advance? If not, why not?” So we started doing that. But what we weren’t doing was asking the candidates if it helped. So…

I've been building digital products and services since the dial-up era. I spent many years working in the private sector. Good design is seen as a necessity. Customers will switch to another service which is easier to use, has a better app, or offers a nicer experience. I now work in the public sector, where…

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…

A few years ago, we installed solar panels on our roof in Oxford - I've enjoyed blogging about them. I've released open data from them, inspected them with a drone, and measured what happened during a solar eclipse. They've even been on the BBC! But the best thing I did, was release this little Twitter…

At a recent Staff Away-Day, we were encouraged to write a "Manual of Me". A quick summary of the general ways that you like to work. I don't spend much time on introspection and I found it disturbingly personal. So here's mine for you to enjoy! Excuse my crappy drawing and even crappier spelling. Here's…

Once in a while, I'll see someone Tweet a "link" to file:///C:/users/... - that's the Microsoft Windows way of representing a location on a filesystem. Usually this means that the user has tried to either drag 'n' drop something, or copied a link from their file explorer. There are some (mild) infosec risks you should…

*sigh* These scams are really common. And pretty easy to pull off. Renting an expensive sports car for a day is relatively cheap. Drive it to some fancy locations, wear a couple of rented designer clothes, perhaps pay for a pretty model to pose as your girlfriend, take a load of photos and you can…
