As I’m writing my new book on functional programming in Scala I started thinking, “What if the person who creates Skynet or the Matrix reads this book and suddenly understands how to create their evil invention? But ... if I don’t create this book, they’ll stay on their previous course in life to be a world-famous cookie baker.”
It’s quite a responsibility, knowing that you could be responsible for a future without great cookies.

“My advice: Don’t let yesterday contain the greatest things you’ve ever done. Make tomorrow contain your next great goal. Because once you feel your greatest days are behind you, you begin to die.”
At the very least that quote is about the importance of having goals.

Besides having a bad memory, I haven’t been able to work with Scala much recently, so I’ve been putting together this list of
for loop examples.
This page is currently a work in progress, and as of tonight I haven’t tested some of the examples, but ... if you’re looking for some Scala
for loop examples — technically called a
for comprehension or for expression — I hope these examples are helpful.
Viktor Klang has a series of blog posts about Futures in Scala 2.12.
As a quick note about Scala Futures, if you want to create multiple
Futures and merge their results together to get a result in a
for comprehension, the correct approach is to (a) first create the futures, (b) merge their results in a
for comprehension, then (c) extract the result using
onComplete or a similar technique.
I’ve been really irritable lately, mostly as a result of not getting an answer to my ongoing health issues. Probably because of this, today I had this thought that when people say, “Nobody loves me,” it occurred to me that it would probably more accurate if they said, “The person I want to love me doesn’t love me.” Then when I saw the following Twitter post just now I thought I might as well go ahead and write what I was thinking. Here’s the text of the Twitter post:
Of all the future perils for which we warn & prepare children, no one ever mentions: “You’ll one day love someone who won’t love you back.”
