Hi, I’m Alvin Alexander. I wrote the Scala Cookbook, Functional Programming: Simplified, Scala Book, and created alvinalexander.com. It turns out that books don’t pay much money, and with most people using ad-blockers, a popular website doesn’t pay much either. So either (a) I raise more money this way, or (b) I go back to programming and consulting work, and that second option won’t leave any time for future writing. So if you’d like me to keep writing about Functional Programming, Scala 2, Scala 3, Java, and more — contribute now to keep me writing! All the best, Al
