Some Blog Site

It’s June, the start of the summer quarter. Time for me to update the theme on this blog.

As is usual, it’s not much of a new theme – all I did was replace the images.
Anyway, here’s a slightly new look. Don’t expect tweaks this time.

Warning: Engineering / computer science discussion ahead. Proceed with caution. Actually, it’s not that bad. Non-engineers might also appreciate this post, as long as they are familiar with the 80s.

I was given the assignment at work of providing a summary of RTOS (real-time operating system) differences. We use 3 different types of embedded operating systems in our various modules, and management was looking at another one to meet customer requirements.

For this application, there is a regular RTOS and a safety (or safe) RTOS for critical equipment. (If you are unfamiliar with those options, here are search results for safe RTOS so you can get more details.)

My summary is that a normal RTOS runs the expected tasks in one common environment, whereas the safety OS runs different tasks in different threads so they are isolated from each other memory- and context-wise.

If that’s still not making sense, maybe this will:

You can task if you want to
You can leave your threads behind
Because your threads don’t task
And if they don’t task
Well they’re no threads of mine

Safety
OS

I’m hoping management wants me to present my summary at the next department meeting so I can put that on a slide.

We went to Pokagon State Park in northern Indiana. I like to mispronounce it as Pokemon State Park, hence the blog title. I had to issue a correction though, otherwise my kids would have been very disappointed when we got there and there were no Pokemon.

Weekend Recap, with Photos:

If you hadn’t read the introduction to this blog post and you saw this photo

would you have guessed it was a state park?

I wouldn’t have.

I made a 360° panoramic photograph of the inn/lodge. Click on it for a larger photo.

Normally, I do my book review post in mid July, after we have gone on vacation. That’s because I don’t normally read full-length books until summer vacation – that’s when I make time for that.

Since we had a spring-break vacation this year, I got to read a couple books earlier in the year.

First book: “Legal Fables” by Ray O. Sage.

This book doesn’t quite qualify because it is not a novel. There is no story; rather, it is a collection of short stories. Each chapter tells how someone (humorously named) has or gets into legal trouble and concludes with a moral (usually that one should consult a lawyer in that situation).

The book was amusing and somewhat educational, especially if you want to know about wills and trusts.

Next book: “I Am Half-Sick of Shadows” (a Flavia de Luce mystery) by Alan Bradley.

If you are not familiar with Flavia de Luce, stop reading this blog, go to your library, and check out the whole series.

If you don’t want the whole series, get the first book (“The Sweetness at the Bottom of the Pie”). I liked all of them except for the second one (“The Weed that Strings the Hangman’s Bag”).

“I Am Half-Sick of Shadows” was good. I recommend it.

Next book: “Speaking From Among the Bones” (a Flavia de Luce mystery) by Alan Bradley.

“Speaking From Among the Bones” was better than the previous book. It would have been my favorite of the whole series except for the ending. I think it’s not a spoiler to say the book ends, but the story doesn’t. In other words, the author may as well just put a giant “To Be Continued…” at the end of the last chapter of this book.

The mystery part of the story is concluded quite nicely and neatly, but the larger themes that run through the series are not concluded. In fact, they become more complicated. I assume it is being setup for a good conclusion in a later book (next book is scheduled for 2014). But it does leave a dissatisfied taste in one’s brain after finishing the book. Your alternative is to wait until the series is done before you start reading it.

Next book: “The Trials of Lance Eliot” by M.L. Brown.

I read this book last year (read my review of Lance Eliot), but I read the Kindle version. Now I finally have the paperback version.

Again, the main problem with this book is that it needs a sequel to resolve some questions. The series is supposed to be a trilogy, but the other two books are not done yet. So you can either order “The Trials of Lance Eliot” now, or wait until the trilogy is complete.

Last book: “Quitter” by Jon Acuff.

I wasn’t originally planning to read this book, but it was a gift so I didn’t want to be rude.

Why was I not going to read this book? Because I’m content. The types of people who want to read this book might call it complacency rather than contentment.

According to the book, I fall into the group of people who believe the “This job just funds my real life” myth. But it works. And I will probably be content until it doesn’t work.

I want to like the book, and I want to heartily recommend it to other people. But that’s because I have a connection with the author, not because of the book itself. The book was fine; I didn’t dislike the book. For people who are not content with where they are in life, this book should be a good help. I’m just not at a stage in my life where I appreciate the book as much as other people do. Sorry for the lackluster review, Jon.

Here I rank one’s chances of regret for various actions:

Always Regret

• reading urban dictionary

Usually Regret

• tattoos

Sometimes Regret

• pressing Send without thinking “how would this look in court?”

Never Regret

• opting for bacon

Here is something else on which to ruminate:
Must you gret something first before you can regret it?

Day 6

Zion National Park

This day we set out early again, mainly because we had a 3-hour drive to get to Zion. The kids did very well. I did very well too, until we tried to park the vehicle. It should be called Zion National Take-the-bus, because there is no parking.
I should have taken a photo of the madness that was the road into Zion National Park – cars parked all along both sides of the road outside the park, everyone walking from their cars, cars waiting in line to get into the park, cars turning around at the entrance because they didn’t have a reason or reservation to be admitted, shuttle buses going back and forth.

We found a parking lot a half mile from the entrance and parked there. We had to change our plans because we brought extra stuff, assuming we could get to our van between hikes for some refreshments or strollers or whatever. We had to leave the stroller and some snacks. We made our way to the shuttle bus stop and got into the park that way.

There was quite a line of pedestrians to get into the park. It seemed to me the reason was the park service had only one person at the ticket booth. By the time we got in the park, most of us were hot and frazzled. Beta was complaining about being hungry, but he couldn’t eat the rest of his sandwich that we packed because we left it in the van.

All that to say this: if you do plan on going to Zion National Park, be prepared to carry everything you need. Do not expect to have your car available for anything.

Really, they should have put the canyon in a better place, with more parking. Or maybe they could widen the canyon so they could fit more parking spots inside it, closer to the trails. They really didn’t think this national park through very thoroughly when they designed it…
