The Andreessen Horowitz website has a blog post titled The Crypto Canon which has links to good resources on what a blockchain is, how bitcoin and others work, Ethereum, and much more.
I wrote the Scala Cookbook for programmers looking for solutions to common Scala problems, and then wrote Functional Programming, Simplified for programmers looking for a simple way to learn functional programming. A few months ago I decided to finish my Scala trilogy and write a book for programmers who don’t know Scala and want a quick introduction to it. With that, Hello, Scala was born:
Here’s a link to an H2 JDBC database tutorial (just some sample code).
With a little luck, I hope to release another 5-10 lessons on my Hello, Scala website tomorrow evening (January 8, 2018).
Just added a few more lessons to “Hello, Scala” including tuples, Scala + Swing, and a complete little OOP example. Also started a Github repo for it.
It’s still a work in progress, but I’m creating a Hello, Scala website as a simple, quick introduction for those interested in learning Scala.
I know nothing at all about Bitcoin, but fortunately arstechnica has this article, Seven questions you were too embarrassed to ask about Bitcoin.
Android 7 comes with a cool new “split screen” feature where you can look at two apps running at the same time. This little pictorial/tutorial shows how to use this split-screen feature.
I just got back into using an Android
AsyncTask, and it took me a little while to re-load the concepts in my head. I used
AsyncTask’s a few years ago, but haven’t used them since.
To help remember how they work, I created a little
AsyncTask example project, and I’ve included all of the source code for that project here. I’ll show all of the source code for my classes and configuration files, and then explain the code at the end.
