What is a morpheme?

Tutoring English, the language might be stripped down to “bare wires”. The tutor mentions the idea of morpheme.

Any language has morphemes. A morpheme is an “atom” of the language – that is, a morpheme is a single-meaning element.

The word walk contains one morpheme: the meaning of moving forward on legs. The word walked contains two morphemes: walk, but also -ed. The -ed carries the meaning that it happened in the past.

Effects of stress and cortisol, Part 1

Self-tutoring about stress and health: the tutor explores some effects of cortisol.

Back in my post from March 14 I bring up cortisol, Part 0. I observe therein that cortisol is released in response to stress. Cortisol, in turn, causes a flood of glucose into the bloodstream without a corresponding increase in insulin. The reason: neither brain cells nor exercising skeletal muscle cells need insulin to take up glucose, while fat cells do. Therefore, the cortisol makes a deluge of calories available for the brain and skeletal muscles so the body can solve the stress it faces.

A consequence of cortisol is that it can suppress normal body functions in favour of the stress response. In nature, the threat would soon pass, then the stress would release and the normal body functions would resume. However, the modern, long-term stress people can face may lead to elevated cortisol long-term. Immunity, digestion, reproduction, and growth can be disrupted. Elevated cortisol, combined with adrenaline and other hormones of stress response, can eventually compromise a patient’s physical and mental health.

Exercise can help regulate stress, as well as consume the immediate calorie flood that accompanies elevated cortisol.

Using say in Perl

Tutoring computer science, new language ideas will always be noticed. The tutor mentions the Perl construct say.

use v5.10; #Apparently you need this to use say.
$var1=”Hey there:)”;
say $var1; #same effect as print “$var1\n”;

I’ve never known of say, but I tried it on a console and indeed, it works. I needed to include use v5.10; for say to work. I understand, however, that the version can be higher.

As a kid, I heard scone pronounced scon; out west, I more often here scone.

Apparently, both pronunciations are correct.

Does having multiple tabs open affect speed?

Self-tutoring about technology: the tutor adds an observation about download speed related to multiple tabs open.

For my phone, there doesn’t seem to be a consistent relationship between number of tabs open and download speed. With 8 tabs open it sometimes reports even a faster speed than with just one.

One way to observe internet speed is the Shaw Speedtest.

What is ping?

Self-tutoring about technology: the tutor explores the idea of ping.

Apparently, ping is measured in milliseconds (ms), and is the time a device awaits an answer from another. The lower it is, the better.

I’ve read that ping below 50 is regarded as good, while below 20 is very good.

What is hiit?

Self-tutoring about fitness and health: the tutor explores the idea of hiit (high intensity interval training).

High intensity interval training means alternation between maximum effort and light effort. Of course, the exerciser needs to warm up first. Then, the typical ratio of (maximum effort):(light effort) seems to lie between 1:1 and 1:2. For example, on the exercise bike, after appropriate warm-up time, the athlete might pedal one minute hard, then 1-2 minutes easy, then repeat the cycle, for around 30 minutes, followed by perhaps a five-minute light-effort cool down. Such might constitute a hiit session.
