Just the other day, my uncle sent me these pictures from NASA’s past mission. Aren’t the photos really something? When I was a kid I wanted to be an astronaut (don’t all kids want something like that at some time or another?), and seeing these pictures remind me of that childhood dream.
Did you know that Sierra Instruments makes thermal mass flow meters for NASA? The meters have to be unbelieveably accurate, because they control the precise fuel mixture used in NASA’s shuttles. I can’t even imagine how exact that has to be!
Sierra Instruments makes and distributes flow meters for other applications, too. I recently read an article about how one of California’s energy plant was switching to meters made by Sierra Instruments — a type of liquid flow calibrator, I believe. And then of course there is their amazing ultrasonic water flowmeter, which can be installed without stopping the flow of whatever liquid is inside the pipes!
It’s amazing where science and technology can take us, isn’t it?

I’ve never really considered information security to be a high priority in my life. Most of my sensitive documents such as bank statements, credit card statements, and old tax returns are stored under lock and key in a file cabinet in my home. In that respect, and very much like a packrat and I keep everything.
After watching a news program a week ago, I realized that my information was not as safe as I thought. Coupled that with my need to make some room in my file cabinet, I decided that I needed to do something about it.
I went online to the website that my employer purchased a Destroyit shredder to see if they had any personal shredder options. Thankfully they did, and I looked for something that would work for me.
After a couple clicks, I had no idea what I was looking at. They talked about things such as strip-cut and cross-cut which was like speaking in a foreign language to me. Before I went any further, I decided I should maybe find some good buying advice that would help me make an educated choice.
I was able to find a paper shredder buying guide that not only helped me learn the jargon, but also put me in a situation where actually knew what I was looking for.
I returned to shredders iShop and proceeded to look through their selections of different home shredder models to find the one for me. It arrived yesterday and I tried it out for the first time today. Not only is my file cabinet relieved to have more space, but I have peace of mind knowing that no one will be able to reconstruct the documents to be used for nefarious purposes.
