Reading Impractical Python Projects

If you experienced the home and personal computing revolution of the early 1980s, you may have read some books that got you hooked up with programming. These books led you through the intellectual adventure of using computing to explore interesting problem domains.

I got a recent book that brought back that fascination and excitement with programming, Impractical Python Projects: Playful Programming Activities to Make You Smarter by Lee Vaughan.


The book is not a Python tutorial or guide. Instead, it presents stimulating coding projects for non-programmers who want to use Python for doing experiments, test theories, or simulate natural phenomena. This includes professionals who are not software developers but use programming to solve problems in science and engineering.

Exploring and understanding the problem domain is an integral part of the book’s projects along with the coding. This is unlike typical programming books where the examples are often trivial, have little or no domain d…

Space Apps for Android: 8 Sep 2019 Update

I released a new update of my book Space Apps for Android: Discover the Best Astronomy and Space Apps on September 8, 2019. If you purchased the book, you can download the latest version for free from your Leanpub library.


This new version comes with the complete rewrite of chapter The Sun, which now has an introduction.

I also added the entries for Eclipse Calculator 2, the best eclipse app, and SunViewer 2, which lets you view the latest solar images.

Why an update? Because I’m self-publishing the book as a work in progress with the Lean Publishing process, so I’m constantly updating and expanding it.
