One new thing I learned in the last week is the `htop` command. It’s a nicely-improved version of the standard top command. This image provides some hints as to its features. If you have a Mac, you can install it with Homebrew.
Scala, Java, Unix, MacOS tutorials (page 101)
This page contains a large collection of examples of how to use the Scala Map class. There are currently well over 100 examples.
A Scala Map is a collection of unique keys and their associated values (i.e., a collection of key/value pairs), similar to a Java Map, Ruby Hash, or Python dictionary.
This week in mast cell disease (MCAS) included temporary kidney shutdown on Wednesday (swollen feet and ankles), insane migraine Thursday, fake heart attack Friday, and hives on Saturday. I used to think it was going to kill me, but now I think it’s just here to torture me.
Back on July 20, 2010, I found this little chalet while walking in a small neighborhood in Wasilla, Alaska. I remember really liking the A-frame style, and also the 1-car, 1-snowmobile (snowmachine) garage. Although looking at it now, it appears there’s no simple way to pull straight in and out of the garage.
If you ever need to drive from the Boulder/Denver, Colorado area to (or from) Santa Fe, New Mexico, the gray route on the left in this image is the most scenic, the one to take if you only get one shot at it. Lots of mountain views and ranches, and many small towns.
Once you get off of I-25, the blue road that goes through Taos is also very scenic, and is particularly pretty in the winter. I usually take the gray road back to Colorado, and the Taos road down to Santa Fe.

This is an excerpt from my book, Hello, Scala. In this lesson I’ll show two examples of applications that use Akka actors, both of which can help you get started with my larger “Alexa written with Akka” = Aleka application.
An Akka “Hello, world” example
First, let’s look at an example of how to write a “Hello, world” application using Akka.
Writing a “Hello” actor
An actor is an instance of the akka.actor.Actor class, and once it’s created it starts running on a parallel thread, and all it does is respond to messages that are sent to it. For this “Hello, world” example I want an actor that responds to “hello” messages, so I start with code like this:
One of the tremendous views from the long bike and walking path in Palmer, Alaska. The Boulder, Colorado area is great, but there’s something about being in Alaska, where the population density is about 1/10th or 1/100th of what it is here that’s really wonderful.
espn.com has a great story titled How it started: First jobs in football for all 32 NFL head coaches. Below are some of my favorites quotes from some of the coaches.
Ron Rivera:
“I was going to make them need me by working as hard as I could,” Rivera said. “I did everything from taking coaches’ cars to get washed and gassed, picking up lunch. I did all the quality control breakdowns. Basically, from the ground up. I learned what it took to be successful. You had to make yourself indispensable, where they had to have you around to help the team.”
A friend of a friend posted this false image on her Facebook page, and several people responded with profane comments about AOC. Finally someone else who actually put some thought into it posted this Snopes page showing that AOC never said anything like this. The fact is, the entire commentary was fabricated. Per Snopes:
“The source of the fabricated article, Taters Gonna Tate, is part of a network of sites and social media accounts operated by Christopher Blair, who produces a high volume of junk news and misinformation, much of it inflammatory, which he presents as ‘satire.’”
The sad thing is that some people don’t think, and they seem to want to believe propaganda like this. Two things are going through my mind after seeing this racism and hatred. First, we really need to focus on the state of education in the United States, both IQ and EQ. Second, I think a lot of people have pent-up anger because no matter how hard they work, they don’t have much money, because in America the rich are getting richer and the poor are getting poorer, and the middle class is disappearing.

One of my favorite road signs in Alaska: “Caution: Yield to All Aircraft.” Seems like great advice. You can find this sign somewhere around Lake Hood, in Anchorage, Alaska.
Summary: How to create a public and private key pair to use ssh and scp without using a password, which lets you automate a remote server backup process.
Over the last two years I've ended up creating a large collection of websites and web applications on a variety of Linux servers that are hosted with different companies like GoDaddy and A2 Hosting. I recently embarked on a mission to automate the backup processes for all these sites, and as a result of this effort, I thought I'd share what I've learned here.
vim colors FAQ: Can you provide details on how to control/configure colors in the vim editor (i.e., vim color settings)?
Sure. When using vim syntax highlighting, a common complaint is that the default color scheme is a little too bold. In this article I'll try to demonstrate how you can change the colors in vim to be a little more pleasing, or at least be more in your control.
As I’ve learned over the last several months, getting Thyrogen for thyroid cancer treatment can be extremely hard, if not impossible or incredibly expensive. These nine pages of notes to my doctor, my insurance company (Blue Cross/Blue Shield), specialty pharmacies like AllianceRx (Walgreens), Accredo, CVS specialty pharmacy, and the Thyrogen manufacturer, over a period of five weeks demonstrates how hard it is to get Thyrogen when you need it.
After going through all of this, my best suggestion is that if you’re having a hard time getting Thyrogen for your thyroid cancer treatment, call the people at thyrogen.com (ThyrogenOne). Because a lot of patients have a hard time getting Thyrogen, they seem to understand the process better than anyone, including my doctor’s office and my insurance company.
Sadly, this tweet about the president, sexual assault, concentration camps, racism, and the state of America in 2019 is all too accurate.
If you work with the vi editor a lot, you'll find yourself tinkering with various vi configuration settings from time to time. Many times you'll want to modify the configuration of your current vi session, and to do that you'll use one of many available vi set commands. In this vi (and vim) tutorial, I'll share the vi set commands I use most often.
