Free Book: Introduction to Data Science, Version 2.0 By Jeffrey Stanton & Robert De Graaf

Introduction to Data Science, Version 2.0 is a free e-book written by Jeffrey Stanton, Professor and Senior Associate Dean in the School of Information Studies at Syracuse University, and Robert de Graaf. It was developed for the Certificate of Data Science program at the School, and serves as an introduction to the key concepts of data science for non-technical readers. The book uses a hands-on learning approach, walking readers through data science concepts and tasks using the R language. It is suitable for anyone who wants to have a slightly technical appreciation of what data science is about, and an understanding of what data scientists do.

Learning the Norman Layout, Week 3

This is the end of my third week learning the Norman keyboard layout. Learning a new layout is quite a big endeavour, as it changes the way I do almost anything, both at work and at home. How well I learn it determines how efficiently I can go about my daily tasks, and how frustrated I get when I make mistakes that slow me down and get in the way. So how is my typing now, after three weeks of practise?

It has been a week since I started learning the Norman keyboard layout. I went “cold turkey”, diving right into the new layout after just a couple of days.

The Nexus Keyboard Could Be the Best Thing Since Typewriters

Computer keyboards have not changed much over the years. Standard keyboards of today come in either ANSI or ISO layouts, inspired by typewriters invented in the 1870s, where keys had to be staggered to leave space for the levers. This staggered layout is unnatural, however, for human hands, especially for the left hand where the slant of the keys goes against the natural movement of the fingers. While a few attempts have been made to design ortho-linear keyboards that align the keys in a straight line from front to back (such as Typematrix 2030, Kinesis Advantage, Truly Ergonomic 207/209 and Ergodox), the Nexus keyboard designed by Geekhack forumer AcidFire could be the best attempt so far in re-designing the keyboard.
