Separable functions in different contexts
I was skimming through the book Mathematical Reflections [1] recently. He was discussing a set of generalizations [2] of the Star of David theorem from combinatorics. The theorem is so named because if you draw a Star of David by connecting points in Pascal’s triangle then each side corresponds to

More code isn't always a good thing, but fewer bugs is.
Read moreThe evolution of full stack engineers
On today’s episode we chat with Mrinalini Sugosh, Developer Relations and Community Manager at CKEditor and TinyMCE. She discusses how modern full stack developers have to master both front and backend skills, stitch the two together, and master adjacent skills like data analysis and security compliance.

Recently Heikki Lotvonen cooked up a very cool idea: what if the colorization of code output on the web could be handled by the font itself. Syntax highlighting, as it were. So rather than accomplish this with a heaping pile of <span>s with classes to colorize the text, the font

Body Roundness Index (BRI) is a proposed replacement for Body Mass Index (BMI) [1]. Some studies have found that BRI is a better measure of obesity and a more effective predictor of some of the things BMI is supposed to predict [2]. BMI is based on body mass and height,

I’ve written a couple posts on the approximation by the Indian astronomer Aryabhata (476–550). The approximation is accurate for x in [−π/2, π/2]. The first post collected a Twitter thread about the approximation into a post. The second looked at how far the coefficients in Aryabhata’s approximation are from the

Write the letters of the alphabet around a circle, then strike out the letters that are symmetrical about a vertical line. The remaining letters are grouped in clumps of 3, 1, 4, 1, and 6 letters. I’ve heard that this observation is due to Martin Gardner, but I don’t have
