Nutrition: glycemic index of vegetable oil

Self-tutoring about glycemic index: the tutor mentions the glycemic index of vegetable oil.

Since it doesn’t contain carbohydrate, the glycemic index of vegetable oil is zero.

Tree identification: sweetgum, part II

Self-tutoring about local trees: the tutor mentions the sweetgum for the second time.

Back on September 15, 2015, I noted a sweetgum tree in Campbell River. Its star-shaped leaves were how I identified it.

Yesterday, I saw one without leaves and didn’t recognize it as a sweetgum. After some research I discovered its numerous spiky fruits, still present after its leaves have fallen, tell that it is, indeed, a sweetgum. This one isn’t big like others I’ve seen, but seems prosperous enough, given the many dozens of fruit hanging from it. I saw it down in Parksville.

Lifestyle: Parksville

Self-tutoring about traveling on Vancouver Island: the tutor comments on his stay in Parksville.

Parksville has given me a wonderful week.

I find the people here friendly and considerate. Last night, I was crossing at a corner. Someone was waiting behind me to make a left turn. They did not enter the intersection until I was on the sidewalk at the other side. Such politeness might be surprising, but not in Parksville.

Wherever I go here, the people I meet say “Hello” and wish me a good day.

The other night, walking home, I saw a business all lit up as if it were open. Yet I was sure it wasn’t, given the lateness of the hour. I looked inside. Two men were playing a board game after closing up shop. Making hand gestures, they were absorbed in conversation as they set up the game. It might have been a sight from another era…unless you’re here.

Everywhere in Parksville, the people have buoyed me during a very busy week. It will be tempting to return here….

Health: a hot shower might make you feel better, but why?

Self-tutoring about the habit of showering twice a day: the tutor wonders if it brings more benefits than cleanliness.

A hot shower can seem surprisingly rejuvenating, but does it bring real change to body chemistry? Perhaps yes.

Apparently, a hot shower can promote oxytocin release in the body. One of oxytocin’s effects is to relieve anxiety.

Believe it or not, a hot shower can also cause the release of growth hormone, which promotes healing.

Apparently, a hot shower likely has true biochemical effects.

Nature: nightcrawlers, part 0

Self-tutoring about worms: the tutor mentions a sighting.

I’m in Parksville this week. The other night I had to go out for a razor because I forgot mine at home. It had been a rainy, windy day. Luckily I went out during a lull, walking around a kilometre.

The roads and sidewalks were wet. After a while I walked over what I first thought to be a stick.

“That was a worm,” I thought to myself.

“No,” I continued. “It’s much too big to be a worm.”

“Go back. You’ll see.”

Retracing a few steps, I did see: it was a worm. Believe it or not, I think it was ten inches long.

During the walk I encountered a couple more that were a little smaller, but another one the same size as the first. I’ve never seen worms that big in Campbell River.

Networks: when one remembers you but it’s changed

Self-tutoring about computer skills: the tutor tells about logging onto a network whose password has changed.

What follows is how I remember the situation. For anyone facing it, the idea might be helpful.

I was trying to get online with a network the laptop has been on before, but whose password has changed. I wondered what the laptop would do.

After a couple of minutes (it seemed a long time), the laptop came back with a message that it couldn’t log on to the network. It didn’t tell why, just that it couldn’t.

I tried again, hoping that it would ask for the new password, but it didn’t. It just said, once again, that it couldn’t log on.

I went to the list of networks and selected the one I was trying to get on. Then, instead of clicking Connect, I clicked Cancel.

I returned to the list of networks, selecting the one I’d just cancelled. Since I’d cancelled it (I’m guessing), the computer treated it as a fresh network, so of course prompted me for the password, which I gave and got online. All good.

Computer maintenance: replacing CMOS cell, part 0

Self-tutoring about computer maintenance: the tutor shares about diagnosing a fading CMOS cell on an aging computer.

We’ve run this Windows 7 computer as our main one since April 2010. Like often seems to happen with a Windows computer, or maybe with anything that lasts a long time, it seems to have gotten better with age. However, perhaps sometime last summer, it began to struggle. My regular readers have noticed posts about my investigation herein.

The computer started running fast even when idle. Then, it wouldn’t wake up after going to sleep. In the morning we’d have to try over and over again to start it. It always did, eventually. What was the problem?

The diagnostics would report an unspecified hardware change as the potential problem. They were right, it turns out, but what, in particular, was the cause?

Early in my research I read that the CMOS cell might need replacing. Typically they are not rechargeable in this context, so like the cell in a calculator or watch, they do die eventually.

Yet, a key symptom of CMOS cell retirement is that the computer doesn’t keep proper time. This one continued to, so I doubted the CMOS cell was fading.

The computer started up easier without any extras attached – USB drives, etc. I finally read that, when a computer is booting, the CMOS cell allows the BIOS to reach out and coordinate the loading of the drivers for the devices attached. A struggling CMOS cell may no longer be able facilitate a boot. I decided the CMOS cell must be dying, even if the computer still did keep proper time.

I looked up our model and discovered that, like many others, its CMOS cell is the CR2032. I opened up the computer, removed it (indeed, it was a CR2032), and replaced it with a fresh one.

This computer started up like it was new and has run perfectly since. I have high hopes we’ll get another eight years out of it:)

Rep range: is change the key?

Self-tutoring about strength training: the tutor mentions the importance of changing rep range.

Rep ranges might be 1-6 (for strength), 8-12 (for growth), and 13 to 20 (for endurance). Yet, the key to best results might be to shift among all three ranges.

Apparently, when a muscle improves in one way, it becomes better prepared to improve in another way, and so on. Therefore, rotating the rep range seems key, rather than finding “the best one.”

Windows: viewing chkdsk results

Self-tutoring about Windows 7: the tutor mentions how to view the results of running chkdsk.

I ran chkdsk today to check the hard drive. Afterwards, the computer restarted, not showing the results.

I looked what to do on the internet. A source link below mentions to open the event viewer from the start box, then look for event ID 1001 under Windows Logs→Application.

I followed that advice and selected event ID 1001 (Wininit rather than Winlogon, I found). There I read the results of the chkdsk I’d run, which reported Windows has made some corrections to the file system:)

Windows: A way to check hard drive health

Self-tutoring about Windows: the tutor shares a way to check hard drive health.

I’ve read that WMIC stands for Windows Management Instrumentation Command-Line. It includes a way to check hard drive health, as follows:

  1. Open command prompt.
  2. Type wmic diskdrive get model, status then press Enter.
  3. A table will appear of the storage devices connected to the computer and their status. A status of OK suggests wmic doesn’t anticipate failure. It can return “Pred Fail” to predict failure.

I ran this command and got OK for the status of the hard drive. A neat bonus is that it gives status for each of the other drives connected to the computer.
