Motley Fool has an excellent collection of Jeff Bezos quotes going back to the 1990s.

If you open your mind for me
You won’t rely on open eyes to see
The walls you built within
Come tumbling down, and a new world will begin
Living twice at once you learn

You’re safe from pain in the dream domain
A soul set free to fly
A round trip journey in your head
Master of illusion, can you realize
Your dream’s alive, you can be the guide but

I will be watching over you
I am gonna help you see it through
I will protect you in the night
I am smiling next to you
(in Silent Lucidity)

(I’ve been having a crazy amount of lucid dreams lately, and as a result I can’t listen to this song loud enough.)

Maybe the sun’s light will be dim
And it won’t matter anyhow
If morning’s echo says we’ve sinned
It was what I wanted now
And if we’re victims of the night
I won’t be blinded by the light.

~ Judy Kay “Juice” Newton, “Angel of the Morning

I’m a fan of Domata Peko of the Denver Broncos. This video helps to show why I like him, he seems like a bundle of happy energy, a real positive force. (There’s also that whole war battle thing, too.)

“And that’s one reason we like to believe in genius. It gives us an excuse for being lazy.”

~ Paul Graham, What You Wish You’d Known

Six weeks after colectomy surgery I’m able to eat some solid foods for the first time since October, 2017. I also hope to start practicing yoga again in a few weeks.

macOS crontab FAQ: How do I run a Unix job (or shell script) through the macOS crontab facility? I keep trying to edit my Mac crontab file, but my Mac won't save my crontab changes, or run my program.

As a quick update in 2024, when you create a macOS crontab-type app with this solution, it will now be shown in your Mac System Settings, under the Login Items section.

For an adult with memory problems (dementia) we’re trying these “You Paint It” kits. The one shown is a collection of forest animals, and they also have dogs and cats, some sort of horse-like characters, and emoji figurines.

I’m surprised when many functional programmers feel the need to say something bad about Scala. As a community, that makes them seem like a bunch of people who aren’t very nice. There are things I don’t like about Haskell, F#, Lisp, Scala, Kotlin, Go, Perl, PHP, Python, C, C++, etc., but I don’t feel the need to take pot shots at any languages or individuals.

This page is a work in progress, but if you need to create a secondary class constructor in Kotlin, I hope it’s helpful.

I haven’t read it yet, but I’m told that Cats, Cubits, and Teleportation is a clear description of quantum computing.

This is the amino acids supplement chart from the excellent book by Julia Ross, The Diet Cure. With this chart you look at the first two columns to find whatever “deficiency” problems you may be having, then look for the amino acid supplement(s) that are known to help with those problems.

I originally learned about this when my thyroid was failing in 2011. A nutritionist told me about this book, and I quickly found out that L-tyrosine was a major help in living through a failing thyroid. Ten years later I still take L-tyrosine after losing my thyroid to cancer, for me it’s a basic supplemental requirement that helps with focus on concentration.

If you’re into puzzles and games of math and logic, The Riddler looks like it will be a good book when it comes out.

I’ve been looking for a way to make Functional Programming, Simplified smaller, but haven’t yet found a way to do that while keeping all the essential information in it. But IMHO, it’s still a heck of a lot easier than reading all of these books on the right:

Apparently 3M, which many people think of as a nice company, has known about the dangers of PFOA and PFOS — which is used to make Teflon and other products — for a long time. Per this story, “Internal studies and other documents show that 3M knew by the 1970s that PFOA and PFOS were toxic and accumulating in people's blood.”

Gimp 2.10.4 was released on July 4, 2018, and has some nice new features.

One thing I was reminded of recently is how consistent the Scala language is. Unlike other languages that have special conditions and special operators for those special conditions — leading to a big vocabulary for those languages — Scala is ... well, it’s just very consistent, and that’s a great thing.

(As a bit of background, I used to be annoyed that Scala didn’t have ++ and -- operators for integers, but after working with other languages, I now understand what Martin Odersky & Co. were trying to avoid.)

With Kotlin you can create lists, maps, and sets with standard functions that are automatically in scope. Here are those functions.

Here are three nice diagrams drawn by Mariko Kosaka that explain HTTP and HTTP2.
