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.
From reuters.com, “Toyota Motor Corp is considering making batteries for electric vehicles (EV) with Panasonic Corp, as it ramps up battery development to help meet its goal for green cars to comprise half of global sales by 2030.” Panasonic is currently the main battery supplier for Tesla.
I know nothing at all about Bitcoin, but fortunately arstechnica has this article, Seven questions you were too embarrassed to ask about Bitcoin.
“About 1.1 billion years ago, two black holes coalesced. They had danced around each other for billions of years, losing energy and swinging closer, until they could no longer resist each other's embrace. Spiraling in, they merged, and released a quaking shout of gravitational waves that echoed across the cosmos.”
Phil Plait on syfy.com has a nice story about a black-hole merger.

Mac Terminal FAQ: How can I change the title on the Mac Terminal app from the Mac/Unix command line?
I've been working on a project where I have three Mac Terminal tabs open at one time, and I found it was much easier to work this way when I changed the title on each Terminal window. This helped me easily identify what I was doing in each Terminal window.
Changing the Mac Terminal title
The basic escape sequence you need to change the Terminal title from the command line is this:

“There is a limit to the time assigned you, and if you don’t use it to free yourself, it will be gone and never return.” ~ Marcus Aurelius

Today I learned that the Android File Transfer tool has a 4GB data transfer limit, but I was able to get around that by using the adb (Android Debug Bridge) command. The short story is that I used this adb command to transfer a 6GB file to my Android system, an old Nexus 9:
adb push ABigMovie.iso /sdcard/Movies
The bad news is that VNC choked and died when trying to play the movie, but the good news is that I found a good way to transfer very large files to an Android device. (I wasn’t really trying to go too far down the road trying to upload DVD images to my Nexus 9, I just wanted to see if I could upload very large files to an Android device. (You can’t fit many ISO images on an old Android device.))
In a related note, I found the Android /sdcard/Movies path through a little trial and error. For future reference, I found that this command lists all of the directories on an Android device:
adb ls /sdcard
The output of that command looks like this:
$ adb ls /sdcard

You can also learn a little more about the Android filesystem reality with a few more commands. After running adb shell, I poked around the filesystem a little, like this:
flounder:/ $ ls -al /sdcard
lrwxrwxrwx 1 root root 21 1969-12-31 17:00 /sdcard -> /storage/self/primary

Functional Programming, Simplified is currently an Amazon best-seller in the functional programming category.
Here’s a story about a hospital robot named Tug that helps deliver food and drugs.
Wow, I saved $600/year on car insurance by switching to Progressive. Geico — who I had been with for five years — wanted to increase my rate to a whopping $680 every six months, while Progressive is only $380 for the same coverage.
Amazon shows that Functional Programming, Simplified is a #1 New Release in its category. That’s cool.
Apple’s Jonathan Ive just gave a new interview at the Smithsonian’s Hirshhorn Museum and Sculpture Garden. fastcodesign.com has quotes from the interview.
From this Cornell University page, Google’s AlphaZero algorithm has been generalized to learn new games given only the game rules: “In this paper, we generalise this approach into a single AlphaZero algorithm that can achieve, tabula rasa, superhuman performance in many challenging domains. Starting from random play, and given no domain knowledge except the game rules, AlphaZero achieved within 24 hours a superhuman level of play in the games of chess and shogi (Japanese chess) as well as Go, and convincingly defeated a world-champion program in each case.”
