Day 3788

Fake news isn't limited to politics. If you try to fix a computer using online tips and suggestions, you will encounter an almost unlimited amount of nonsense. It's frustrating to wade through inept YouTube videos, argumentative user forums, and out-of-date manufacturer tutorials, but you can still learn a lot. That's how I spent my morning. I'm still trying to figure out what went wrong in yesterday's botched computer upgrade. I eventually learned enough to ask some intelligent question when I was able to connect with a tech support person later in the day. A sane person would probably realize that this computer is too old and give up, but I am determined to fix it.

We got a lot of rain overnight, but the skies were already starting to clear up when we got up this morning. As soon as the rain quit, we took Dawn on her morning walk. We took a different path today and saw some parts of the park we rarely visit. Dawn loved the cool, overcast weather. It was windy though and I should have worn a light jacket. It's almost impossible to know what to wear at this time of year. You can be cold one minute and then hot five minutes later. No complaints however. 60 degree days are so much better than 100 degree days.

Our Pulse Oximeter arrived in the mail today. Janet and I both have excellent blood oxygen levels. We'll add this little gadget to the infrared forehead thermometer and growing stack of masks on a shelf in the entry hallway. I was curious how pulse oximetry works. The device clamps on your finger  and sends two beams of light through your skin, measuring the level of oxygen saturation in your blood. By comparing the ratio of the red light to infrared light that is absorbed by the blood, a little computer in the oximeter can quickly determine your current blood oxygen levels. For an inexpensive little device, it is all very complex and surprisingly accurate. I have an oxygen saturation level of 97%. Not bad.

I wonder what I'll be measuring next month. People have become obsessed with their health lately.  Some of this is a good thing, but there is a lot of paranoia as well. Nobody wants something invisible in the air to kill them. When I see people driving around alone in a car wearing a mask and gloves I thing we may have gone too far. I'll give these people the benefit of the doubt however. Maybe they are headed toward a crowded destination and just wanted to get ready ahead of time. The masks I see in the park still baffle me. Usually these people are walking alone and are nowhere near another person. This is what fear will do to you. I continue to believe that fresh air is good. I'm not going to ride in a crowded elevatory with you any time soon though.

Tomorrow it's time to go to the store again. I don't really enjoy these excursions, but they don't take long. Grocery shopping is the only time I feel like I'm living in a science fiction movie. I don't know if I'll ever get used to seeing a store full of people walking around wearing masks. I ordered a new battery this evening, along with a few more installation tools for my laptop. I don't know if this will solve my problems, but I hope so. The computer still runs on AC power with the battery removed, so at least I haven't ruined the logic board. I'd like to say tomorrow is a new day, but it's still groundhog day at our house.

Day 3772

We walked really early this morning to avoid the rain. Although there were all sorts of severe weather warnings, it never rained. It's hard to predict anything these days. There was virtually nobody in the park this morning. I don't think overcrowding is going to be a problem until we get a warm, sunny weekend. Personally, I like the overcast days. Everything looks greener and it's easier to photograph things without hard shadows. I never understood sitting out in the sun anyway. It's terrible on your skin.

Another box of disposable masks arrived today. We're going to have plenty of masks. I'm learning not to sneeze in public. It's not an easy thing to do when you have terrible Spring allergies. Maybe mind over matter actually works. I still have hay fever and sneeze a lot in the house, but almost never do when I'm away. If things get much worse, I'm afraid they're going to start arresting people who sneeze. Definitely don't want that.

I read an interesting article today where a leading pulmonologist said that if everybody started measuring their oxygen saturation levels using one of those inexpensive Fingertip Pulse Oximeters at home, a lot of coronavirus complications could be avoided. Evidently blood oxygen levels start going down way before you develop pneumonia and he thought that a reduction in blood oxygen might be a reliable early sign that you have the virus. Sounds good to me. It makes sense that if you began treatment before you became deathly ill, you would have a lot better chance of recovering. Maybe I'll get one of these little things that fits on your fingertip. My doctor always uses one whenever I get an exam and they aren't expensive. Actually my Apple Watch is supposed to have this capability after the next system upgrade. Might not be a good idea to wait that long though. By the time this is over, I'll probably have a closet full of high-tech devices to keep me healthy.

I reviewed the installation video for the solid state drive this afternoon and I'm a little more confident that I can do the complicated computer upgrade myself. I pre-assembled a few of the components today and will be ready to take the computer apart tomorrow. I wish this computer was a traditional tower where it was easy to access the internal components directly. I've replace processors, hard drives, DVD drives, memory, and other things in computers many times before. This is different though. I've got to remove the glass front protecting the screen and then remove the entire screen itself to gain access to the broken hard drive inside. There are lots of tiny wires that have to be removed and replaced without breaking them. In theory, this repair should be easy if I'm slow and methodical. I'm kind of clumsy though. It's a miracle I haven't fallen off the roof yet.

I keep checking my e-mail to see if there is any news about media accreditation for the Crew Dragon launch at Kennedy Space Center or about the status of my McDonald Observatory article at Sky and Telescope. In my own little world these things are still important. I don't want to bother people because I know they have more important things on their mind. It's still hard to be patient though. Maybe I'll hear something soon.

Until then, I'll continue drinking my morning smoothie, taking Dawn on long walks, patching the roof, photographing Spring flowers, and writing the blog. It's amazing how quickly little things like this can fill up a day. I could write a book about sheltering in place. I doubt that you'd read it though. Most of you want to get back to normal. For me, this is normal.
