A system to help you remember more of what you read
Five years ago I realized that I remembered almost nothing about most books that I read. I was reading all kinds of non-fiction - pop-psychology, pop-economics, pop-sociology, you name it - and felt like quite the polymath auto-didact. But one day, after I had finished blathering at a friend about how much I had…

All clocks are 30 seconds late
OK, this is going to sound crazy: I believe all clocks are 30 seconds late. Let's get a few things out of the way: this is neither about time zones, nor l...

I was tricked into thinking I had “grit”
I was tricked into thinking I had tons of grit as a student. I worked hard in school. I put in long hours. I stayed up all night reading and preparing for debate topics, doing homework, writing essays. It was easy for me to burn the midnight oil. I enjoy

Programming languages that blew my mind (2023)
I’ve been a programmer since the age of 8, and some kind of developer for most of my life. Throughout my life as a coder, both hobbyist and professional, I’ve learnt plenty of programming languages that felt like cookie-cutter clones of each other, but also a few programming languages that changed the way I looked at…

A bad day at the office
While looking for something else, I came across this rather incredible photo in the Imperial War Museum collection. That's a seaplane stuck 300 feet up a 350ft tall radio mast! If that's not amazing enough, the pilot was rescued by three men who climbed up to retrieve him. And he survived.

Teaching C
I was hoping you would mention the dynamic checkers, ASAN etc. My fear is people will start using these but not understand how to really use them properly. Since they’re dynamic checkers you really need a good testing harness and test cases to go with it. The bugs ASAN/TSAN etc catch are usually strange boundary…

Death by PowerPoint: the slide that killed seven people (2019)
We’ve all sat in those presentations. A speaker with a stream of slides full of text, monotonously reading them off as we read along. We’re so used to it we expect it. We accept it. We even consider it ‘learning’. As an educator I push against ‘death by PowerPoint’ and I'm fascinated with how we

Why are D-sharp and E-flat considered to be two different notes?
Why do the black keys on the piano each have two different names? If the posts on r/musictheory are any indication, this is a persistent point of confusion, especially when music theory teachers ge…

Programming: Doing it more vs. doing it better
A few years ago, very early into my programming career, I came across a story: The ceramics teacher announced on opening day that he was dividing the class into two groups. All those on the left si…
