How to do Statistics Wrong

Telling people that they are doing statistics wrong is a cottage industry that I usually want nothing to do with, for various reasons including the fact that the naysayers are often blindly repeating stuff they heard but do not understand.

It has been a long time since I’ve written any machine or assembler code, and it is a rare day that I hand construct a logic circuit using transistors. But it is comforting to know that these skills and the knowledge associated with them still reside in some form or another in the world of…

Arduino Inventor’s Guide

First, a word about Arduino and why you should care. An Arduino is what is called a “prototyping micro-controller” aka “really fun electronic gizmo toy.” Micro-controllers are everywhere. When you “turn on” a machine in your house, chances are there was already a micro-controller sitting there, running on a minute bit of juice from a…
