Feeling old

This year, one of my nieces started her first year of undergrad at the University of Idaho, the other one started 8th grade. A friend from my Detroit days has two daughters in high school now (I remember seeing them visiting the office in a stroller). Nala will be turning 10 this year and Simba will turn 9 a few months later.

On top of all this, I need reading glasses now. All of this is making me feel a little Old now.

On the plus side, we’re in a better position financially than I think I’ve ever been in before, and on a good path to improving it even more. The list of things and activities to keep me entertained continues to grow.

Getting older, but things are pretty good these days. I’m quite pleased with that.

Achievement unlocked: Emergency funded

We’ve reached another financial milestone!

After reaching the debt-free (non-mortgage) point last year, our next big goal was to fill up the emergency fund. We had a target of 6 months for the emergency fund and today we made it to that goal.

Connie’s been doing a great job at keeping us on track and I’ve been doing a pretty decent job at resisting the temptation to buy all the electronics things to play with out at the workbench.

It’s a good feeling having the emergency fund filled up. It gives me a sense of security that I don’t think I’ve had before. It’s nice knowing that there’s this financial cushion behind us and that if anything major happens, we won’t have to scramble much to deal with it.

Hopefully we won’t need to tap into it, but it’s there if we need to, and that’s a good feeling.

Now our next goal is to get back to funding the retirement accounts.

Diving into Asimov

My latest reading obsession has been Isaac Asimov. I’ve always been a big scifi reader, especially in my teens, but none of Asimov’s books ever ended up in my library. I certainly knew of him, but for whatever reason never read any of his books until now. My scifi tastes were more along the lines of Robert Heinlein, Anne McCaffrey and Frank Herbert.

Several years ago (back in 2011 according to my Goodreads list) while browsing the shelves at Mr. K’s, I came across 3 of the 5 books from Asimov’s Foundation series (books 1, 3 and 5), and decided to pick them up. They sat on the shelf for a while before books 2 and 4 joined them on the shelf.

I finally got around to reading the Foundation series at the beginning of the year. I had just finished reading the final book of Robert Jordan‘s epic Wheel of Time series and needed something different to read. I was feeling like getting back into scifi again, and Asimov fit the bill perfectly.

3 months of Asimov immersion and I was finished the Foundation series. Fantastic series that spans several centuries. I really enjoyed reading it.

Having whetted my appetite, I started looking for some of his other books and acquired a copy The Robot Novels, a compilation of the first three books of the Robot novels, and Robots and Empire. They play a prequel role to the Foundation series, and are more scifi whodunnit mystery novels. I found them very entertaining to read. I want robots now. Just about to start on Robots and Empire, and looking forward to seeing how this one is and how it fits into the Galactic Empire scheme of things.

After the Robot novels, I have the Second Foundation series, and Prelude to Foundation to dig into. The Second Foundation series should be a little different. While they’re in the same setting, the three books were all written by different authors. Looking forward to getting to those books.

After that I’ll start looking for the books in the Galactic Empire series.

Retrospective pilgrimmage blogging

Back in April my wife, Connie, went to Rome for 3 weeks for Easter and the canonization of two popes.

Four months later, she’s “live” blogging each day of her trip. For her, it was a pretty amazing trip. She got to experience a lot of Rome, and visit a lot of places with historic and Catholic significance. There are also lots of neat pictures too.

She’s half-way through her trip now. Head on over and follow her along on her journey.

Nexus 5 X-ray – Hi Res

A little while ago, I took a radiograph of my Nexus 5 using a conventional radiographic unit.

Today, I was doing some testing on a mammography unit and acquired another x-ray of my Nexus 5. The mammography unit uses a much smaller focal spot, and will produce much sharper images. However, with the much lower kV mammography units use, it’s a lot harder to get adequate penetration through denser objects (like circuit boards and batteries).

This image was acquired at 34 kV and 120 mAs using the large (0.3 mm) focal spot. Its pretty easy to see that this one is a lot sharper than the other image (click the image to embiggen to all it’s glory).

The main circuit board area towards the top as well as the battery is harder to see through than the other version, because of the lack of penetration of the low energy x-rays. It’s a lot easier to see some of the detail in the circuit board at the bottom of the phone, because there’s less to go through there.
