In 1988, three engineers came together and developed one of the most clever solutions to the problem of detecting when two complex objects collide. Their solution, the Gilbert Johnson Keerthi (GJK) algorithm, named after the authors, made an incredible impact in the fields of robotics, control, and computer graphics. This video is about understanding this ingenious algorithm from first principles.

Merging the Trump and CHH personas together: How would I talk about my Substack if I were Trump? / This 15-minute, one-take improvised Trump impression brought to you by mental illness.

This has no right to be this good.

Let’s learn and grow. New things are cool!

Simple economic arguments for why solar, batteries, and other renewable energy technologies are possible RN and clearly the future.

And then some much needed discussion of politics.

The Game Awards 2025 sparked yet another round of indie discourse with Expedition 33‘s historical sweep causing many to ask what does it actually mean for a game to be “indie”?

The pain of semantic drift.

The tsundere is a well-known anime trope, that many people still love to this day. But something happened to it since its inception, and I want to talk about that.

The “database” is a very interesting comparative media concept; will keep it in mind.

Waifus are a very well-known part of anime culture. So many have strong opinions on them, and yet very few know the full story.

Great way of explaining this classis paradox in analysis using uniform convergence.

One of most people’s biggest complaints about anime is the abundance of fanservice. But what is it? And is it always bad? Let’s take a deep dive into anime fanservice and find out.

This is a good video, and I especially appreciate its sex-positivity, but I do wish the author applied more of a feminist lens. People reacting poorly to fanservice as a concept goes far beyond it being utilized poorly and Puritanism, me thinks.

A viral tweet made me curious about looking into the history of fanmade adult content, and I ended up diving into a rabbit hole that goes further than you could ever expect
