I use my favorite images as screensavers, and this “hoodie” image of Luke Skywalker from Star Wars Movie #7 is a recent favorite. I found an image online, then worked with it in Gimp to get a decent effect. This Luke Skywalker sketch shows another approach you can take with Gimp.

This is a small image of a painting I bought a few years ago in Santa Fe, New Mexico, called “Starry Night Over Santa Fe.”

As a brief note today, I have said to my doctors multiple times, “My kidneys itch.” If you have experienced the same feeling, a solution I have found for this problem is to take these AZO Cranberry Urinary Tract Health tablets.

As I’ve written here several times before, I’ve been treated for kidney stones three times so far, and kidney stones keep coming back, and this is a simple product that gets rid of the “itchy kidney” feeling. (Sometimes it also helps to help with the “pain of stones in the kidneys” feeling.)

Personally, I have allergic reactions to the AZO Urinary Pain Relief Maximum Strength product, so I can’t take that much if at all, but I can take the cranberry product every day without an issues.

From this article at psypost.org:

“In a recent study published in Consciousness and Cognition, researchers at Northwestern University showed that a smartphone app using sensory cues can significantly increase the frequency of lucid dreams—dreams in which a person is aware they are dreaming while still asleep. This study marks the first attempt to apply a lucid-dreaming method called Targeted Lucidity Reactivation outside of a lab environment, demonstrating that even a simple at-home approach can help users experience more lucid dreams.”

I’m sitting here working this morning when I start to hear that familiar scratching, crawling sound outside. In a few moments, the squirrel’s head appears from the right side of the window. He’s hanging sideways, three stories off the ground, and looking in, about twelve inches from my face. It’s cold outside so I had the window closed, but I slide it open.

“Dude, Cheerios,” he says.

“Oh shoot, I forgot,” I say.

By the time I walk to the kitchen, get the box of Cheerios, and open the door to the deck, he’s already there, waiting.

I found this “roadrunner in hightops” in the SouthwestIndian.com catalog.

I just heard about the book Live to Forgive this morning. The introduction on Amazon says it all: “In Live to Forgive, former ESPN producer Jason Romano walks readers through his personal journey of forgiving his alcoholic father. Through sharing his own story, Romano invites readers to enter into their own messy journeys of forgiveness-to fully feel their pain, evaluate their pain, transform their pain, and ultimately forgive those who caused their pain. The only route to freedom and peace is forgiveness.”

This blog post is part of a new series of blog posts I call “Conversations With Robots.” I choose a topic and then begin talking to my robot/A.I. friends about it. Today’s discussion starts with, “Do you know what Shinzen Young did to get through his Shinto training? I just saw that he mentions Deity Yoga as part of his training.”

Scala 3 FAQ: How does this ZIO HTTP and ZIO JSON code works, specifically the derives JsonEncoder portion of the code:

case class Greeting(message: String) derives JsonEncoder

Solution

In Scala 3, the derives keyword is used to automatically generate implementations for type classes. Here’s how this works in the context of ZIO JSON.

As a brief note, if you need to debug a ZIO HTTP Request value, I just created this function to return its values as a String, and it appears to work properly:

I’ve written a lot about meditation before, and in this post I’d like to talk about something different that I do from time to time. You see, where many people like to go to a movie or watch the television, I use my meditating power to create my own “holodeck in my mind” to do anything I want to do.

I call this a “The Lion, the Witch and the Wardrobe” meditation, because I start by closing my eyes, start meditating in something like a savasana style, and then mentally go out through the back of a closet in a house I used to live in.

Once I come out the other side of the closet, I come to a path, where I take an elevator ten stories down into my mind, and that brings me to a Star Trek-like holodeck, as shown in this image:

As shown, the holodeck has a virtual recliner where I can sit, relax, and start doing anything I want.

“Courage doesn’t always roar.” I just found this image in a folder on one of my computers. I don’t remember where I took this photo, but I think I took it at a small restaurant in Boulder or Louisville, Colorado. The text comes from Mary Anne Radmacher.

As a brief note, this is my IntelliJ IDEA keyboard/keystroke characters cheat sheet for macOS computers. This is the actual cheat sheet I look at on a daily basis, organized in the way I want it organized.

Back in September of many years ago, I left the little cabin in Talkeetna, Alaska, and started the long drive back to the Lower 48.
