Books by Karl Schank about computer science, programming, PM, and Christian faith 
Jesus Saves … but How?
We’ve all heard that “Jesus saves”. Turns out, it’s true! But must we take that on blind faith?
Not at all! There are reasons. But most people, even most pastors, don’t know them.
It’s logical, rational, and it all makes sense. Frankly, it takes a lot more blind faith not to believe than it does to believe! But to find out, we have to drill down and keep looking and asking “Why?”. That’s why I wrote this.
Spoiler: The short answer is that we, ourselves, actually chose eternal death! How can we fix that‽
But I’m getting ahead of myself. Read the book to find out why, and what to do about it. It also briefly touches on why our great God is a Trinity.
Good on Kindle, better in paperback.
Available on Amazon at low cost as paperback and Kindle e-Book.
On Programming: A How-To Guide
The first course in computer programming is often taught “wrong”. It too often instills bad programming practices while concentrating on syntax.
We can do better.
I’m a programmer and teacher at heart. My first career was as a computer practitioner. My second was teaching college courses in computer science, information systems, IS management, and IT project management.
I found that bad practices had to be un-taught before good practices could be freshly taught. So I taught it “right” in the first place. A survey of the second programming course showed that my first-course students performed significantly better in the second course than did others. That lent additional credibility to these methods.
This book now shares it with a wider audience for beginning programmers. Additional tips from my (first) career spent in computing are also provided throughout this book.
A highlight is extended examples constructed and shown step-by-step throughout this book.
Another key feature is flowcharts, Nassi-Schneiderman charts, pseudo-code, and data flow diagrams for all programming structures.
This is a practical guide to how to do programming. Not the syntax of a particular programming language, but how to write programs. In fact, how to write or code quality programs, and know that they’re right. Part of the beauty of this approach is that this is essentially timeless and language-independent. It is not made obsolete with every choice of a new language or every change or update to a language compiler.
Good on Kindle or in paperback.
A Revelation of Love:
A study of the Bible book of Revelation
The book of Revelation is an engrossing page-turner – the ultimate action-packed thriller, with the ultimate battle and brutal consequences. Yet it’s also the quintessential love story. And it’s all true!
The time is short. Revelation is Jesus’ last warning: be alert and prepared for what’s coming! Revelation may seem scary, but it speaks of divine love. It was written to reveal Jesus in His glory and allay believers’ fears. And to instill the fear of God – and consequences – in nonbelievers.
Walk through this study. See the plot thicken. See God repeatedly kick it up a notch. Yet infernal enemies get worse and worse, until it all comes to a head. Will we make it? Is there hope?
There is! But how?
Let’s see, as Karl Schank leads us step by step through what Revelation actually says – and why there’s great hope for us.
