En ny titt på det finurlige fenomenet “kvadratrotord”

Jeg blogga for en god stund siden om en matematisk finurlighet jeg leste om på futilitycloset.com, noe som de kalte root words. Jeg ga det da et norskt navn kvadratrotord.

Visualizing 100k decimals of Pi, Tau and e with Python

Having an interest for numbers, Linux and small scale programming and scripting shortens the route to test out things like this. It generally starts out with: “I wonder what that would look like” and ends in a continuous awe for numbers, programming and Linux.

Type the Vulcan salute anywhere in Linux

Type the Vulcan salute (made famous by Spock) anywhere in Linux like this: ctrl + shift + u followed by 1f596 + spacebar 🖖 (or any unicode symbol) 🚀 1f680 is cool too 😉 For those in Microsoft Windows, there is hope. Only some programs like outlook and word are supported, but not browsers. I […]
