Finding tangent circles

If three circles are all tangent to each other, you can find two more circles that are tangent to all three, and the equation for finding these new circles is remarkably elegant. This is Descartes’ theorem. Two tangent circles To illustrate Descartes’ theorem, we first need three mutually tangent circles.

Do AI coding tools help with imposter syndrome or make it worse?

Spoiler: Yes.

How to develop technical interview questions this year and beyond

Several years ago, technical interviews were dominated by whiteboard exercises and brain teasers. But ask any engineer or developer today, and they’ll tell you: old-school tests and quiz methods rarely reflect the work they actually do.  Thankfully, hiring teams have caught on. Now, the most effective interviews look a lot

Primitive Pythagorean triangles with the same area

A Pythagorean triangle is a right triangle with integer sides. A primitive Pythagorean triangle is one in which the sides have no factor in common. For example a triangle with sides (30, 40, 50) is a Pythagorean triangle but not a primitive Pythagorean triangle. It is possible for two primitive Pythagorean

Base58Check encoding in Python

The previous post began by saying “Bitcoin’s Wallet Import Format (WIF) is essentially Base58 encoding with a checksum.” More specifically, WIF uses Base58Check encoding. This post will fill in the missing details and show how to carry out computing Base58Check in Python. There are multiple ways to stub your toe

Most legible font for WIF

Bitcoin’s Wallet Import Format (WIF) is essentially Base58 encoding with a checksum. It is meant to a human-friendly way to display cryptographic private keys. It’s not that friendly, but it could be worse. The checksum (the first four bytes of SHA256 applied twice) is appended before the conversion to Base58, so
