A trick to eliminate 2π (sometimes)
As a physicist, I’ve learned that the presence of 2 π 2\pi 2 π [▼] [ Or rather τ \tau τ , as it should actually be called . ] in a formula usually spells trouble. It’s kind of annoying to write by hand, easy to forget, and it’s dimensionless, so you can’t easily check if you forgot to divide or multiply by it…

Making Games
In March 2018, I had been a full-time indie game developer for four years. My heroes were Jonathan Blow, Lucas Pope, and Robyn and Rand Miller. I had 2,500 Twitter followers, an ambitious title under my belt with thousands of sales, and a free office in a hip coworking space near downtown Columbus, generously provided…

Fast machines, slow machines
Well, that was unexpected. I recorded a couple of crappy videos in 5 minutes, posted them on a Twitter thread, and went viral with 8.8K likes at this point. I really could not have predicted that, given that I’ve been posting what-I-believe-is interesting content for years and… nothing, almost-zero interest. Now that…

The quest for a simple smartwatch
My trusty old smartwatch recently stopped working. It was a Garmin Vivomove HR, a minimal hybrid watch with regular watch hands and a tiny hidden screen that showed notifications and messages. It served me well for quite some time but unfortunately the hidden screen has stopped working and it would cost me as much to…

Solving “Two Sum” in C with a tiny hash table
I came across a question: How does one efficiently solve Two Sum in C? There’s a naive quadratic time solution, but also an amortized linear time solution using a hash table. Without a built-in or standard library hash table, the latter sounds onerous. However, a mask-step-index table , a hash table construction…

Why write?
As a reaction to the previous article on how to write a scientific paper, I got some reactions from friends and colleagues, the underlying message being that they would rather like to understand why writing can be important. There is indeed a tendency to see academic writing as a tedious task that one should try to…

Profits are driving inflation. When will politicians and the BoE admit it?
The Bank of England has raised interest rates to 4%, supposedly to tackle inflation. There is just one problem with this decision. The Bank knows that much of the inflation we are suffering is being driven by rising oil and energy prices, largely resulting from conflict in the Middle East. It also...
