space.com has this article about scientists going rogue as “a response to the Trump administration's order for at least four government agencies to stop all communications with the public.”

I don’t know what happened to Freedom of Speech in the U.S., but I like this.
After working with Scala for a long time, I had to come back to Java for a while to work on an Android app. Right away I missed a lot of things from the Scala world, including all of the built-in Scala collection methods, and other things as simple as the Scala
If you haven’t used them before, a Scala
Tuple class lets you write code like this:
Tuple<String, Integer> t = new Tuple<>("age", 41);
If you’re comfortable with generics, the Java implementation of a
Tuple class like this is simple:
When I was sick last summer I couldn’t even come close to thinking about a
Map while programming. Feeling much better these days after radically altering my diet, I have used many maps over the last two days to solve programming problems elegantly:
Map<Tuple<Position,RatingType>, Spinner> positionRatingSpinnerMap = new HashMap<>();
That code gives me an easy way to lookup an Android
Spinner widget based on a football player’s position (QB) and rating type (short passer, long passer, runner).
I have to say, it feels good to have my brain back.
The top five regrets of the dying:
1) I wish I hadn’t worked so hard
2) I wish I had stayed in touch with my friends
3) I wish I had let myself be happier
4) I wish I had the courage to express my true self
5) I wish I’d lived a life true to my dreams instead of what others expected of me
When you have a rare genetic mutation (I prefer the term “posthuman”), doctors like to give you orange jugs.
One of my gripes with both MacOS and Ubuntu is that it’s harder than it needs to be to grab a window corner or edge to resize it. IMHO, designers are choosing form over function.
This page from the Busy Coder’s Guide to Android discusses Android performance, including the Android hardware acceleration setting shown in the image.
Back in 2009 I had a concussion. At some point after that I drove to Illinois to see my family. I was tired after the drive and fell asleep on my sister’s couch, only to be awakened by a loud noise. I opened my eyes and looked in the direction of the noise. A woman standing in the kitchen looked at me and said, “I’m sorry, did I wake you?”
I replied, “Um, that’s okay, no problem.” I didn’t know who the woman was, but she seemed nice, and really sorry for having made the noise.
After she turned and walked away I looked around; I didn’t know where I was. My first instinct was to panic, but I tried not to. I thought hard, “Where am I? Who is that woman?” I’m sure that I also thought, “Who am I?,” but as I write this I remember those first two questions the most.
After at least ten seconds of trying to control my panic and search my memory, it finally came back to me. I was Al, the woman was my mother, and I was at my sister’s house. The panic subsided.
I write this because of a dream this morning, and because I can only begin to imagine the fear that people with dementia/Alzheimer’s must deal with on a regular basis.
I just learned that MacOS has a softwareupdate command, and further learned that it has a --ignore option, which may or may not let you ignore useless updates. For example, my Mac prompts me daily to update Keynote, Numbers, and Pages, which I rarely (rarely!) use, so I don’t want to bother updating them. I’m hoping the a
softwareupdate command will help me with this.
Forbes has a good article on the causes of the Samsung Note 7 battery explosions, including everything Samsung did to understand the problem, and a little bit about where they’re going from here.
“Awareness admits no obstructions. It can be boundless even when we are confined.”

“And all becomes clear. Wish I could make you see this brightness. Don’t worry, all is well. All is so perfectly, damnably well. I understand now, that boundaries between noise and sound are conventions. All boundaries are conventions, waiting to be transcended. One may transcend any convention, if only one can first conceive of doing so. Moments like this, I can feel your heart beating as clearly as I feel my own, and I know that separation is an illusion. My life extends far beyond the limitations of me.”

Dear diary: Filed under the category of “transparent dangling carrots,” today I learned/realized that there is a surface reason the Dalai Lama talks about practicing compassion, and also a much deeper reason. It’s really quite a trip, though with my limited knowledge, for all I know it’s turtles stacked on turtles stacked on turtles.
(A diary entry from January 21, 2015. Dalai Lama quote: “If you want others to be happy, practice compassion. If you want to be happy, practice compassion.” Image from this link.)
“Do not fall in love with people like me. I will take you to museums, and parks, and monuments, and kiss you in every beautiful place, so that you can never go back to them without tasting me like blood in your mouth. I will destroy you in the most beautiful way possible. And when I leave you will finally understand, why storms are named after people.”

Ubuntu is running great on my old 2008 iMac, but if you’re having Linux performance issues, here’s an ArchLinux page titled “Improving performance.”
I was laying in bed last night, waiting to fall asleep, and the power went out. As I laid there thinking about how cold it would get, a gray telephone we had many years ago began ringing in the closet. I wondered what it was doing in there.
Instantly the scenery changed and I flashed back to an event I didn’t know about twelve years ago. As I observed it, it made me sad.
Then I kept going back in time, first to one event and then another.
There seem to be a few different ways to type “smart quotes” on Ubuntu Linux, including using keys (keystrokes) like AltGr and Compose. In this tutorial I’ll document an approach that works best for me: creating simple macros I can assign to simple keystrokes rather than having to use more-complicated keystrokes.
