Philosophy, Religion: how to achieve a perfect life

For me, religion involves constant self-tutoring. The tutor shares an observation from Abhay Charanaravinda Bhaktivedanta Swami Prabhupada, founder of the Hare Krishna Movement.

At this festive time, people are striving to keep their relationships strong. During the year’s darkest days, doing so makes sense: humans survive by relationships, and they love the light.

I think we live in a wise era: virtually everyone I hear wants something immaterial, be it relationship to God or to other people.

Whether you are surrounded by people in bright festivity, or alone in a room lighted only by the computer screen, does the following observation intrigue you?

If you understand what is God and try to love Him, your life is perfect.

-Abhay Charanaravinda Bhaktivedanta Swami Prabhupada

Happy holidays:)

Cholesterol: hdl vs ldl

More lifestyle tutoring: the tutor continues to research cholesterol.

Perhaps many of us have heard that HDL is the “good” cholesterol, while LDL is the “bad”. What’s the difference?

HDL: collects cholesterol from the blood and conveys it to the liver, where it will be cleansed from the body.

LDL: conveys cholesterol to an artery, where it may be deposited to form plaque. As a result, the artery wall thickens, while its room for blood passage decreases.

Lifestyle: Shaw remote replacement

Lifestyle, for me, means constant self-tutoring. The tutor mentions a good experience with Shaw Cable.

My family loves TV. Eventually, after so much use, the Shaw remote wore out. Some buttons, in the end, were very difficult to activate. Watching my wife struggle the other night, I decided to act.

I always try Shaw Chat first – it’s, in my experience, very quick and convenient. I waited only sixteen seconds to reach an operator. Geoffrey confirmed that I could just bring the worn-out remote to the Shaw store and they would replace it over the counter. The new one even includes batteries:)

Kim, at the counter, handed me the new remote and asked if I needed help with anything else. I said I was thinking about changing some packages to lower my bill but would happily do so online, at home.

“Let’s take a look,” she began. She immediately found some ways to save me money on the next bill and gave me other savings options to bring home for family approval.

Ten minutes after leaving my home, I was back with the new remote, anticipating a lower cable bill next month. Thanks, Shaw:)

Computer science: what is a namespace?

Tutoring computer science, terms are so important. The tutor defines namespace.

A labeled data structure that can contain its own definitions of variables, functions, files, etc.

An example of a namespace is a directory (aka, folder). Imagine two different folders – Folder0 and Folder1. Further, let’s imagine each contains a file named file-x, but the file-x in Folder0 is different from that in Folder1. Such a situation is possible because the full names of the two versions of file-x are different: one is Folder0/file-x, while the other is Folder1/file-x. We could also say that one version of file-x is from the Folder0 namespace, while the other exists in the Folder1 namespace.

Lifestyle: cooking: substitute for baking powder

For me, learning to cook means constant self-tutoring. The tutor tells of a substitute he used, successfully, for baking power.

Last night, I planned “breakfast for dinner”: pancakes. However, the recipe I wanted to use calls for two teaspoons baking powder; at best I had only one left. My wife said the store was crazy busy, so I had to improvise.

I surfed to, where I learned of ten possible substitutes for baking powder. I chose to use 1/4 tsp baking soda plus 1/2 tsp vinegar.

I added the baking soda to the dry ingredients, then, at the last instant, added the vinegar to the mix of egg, milk and oil. Next I mixed the wet and dry ingredients as indicated (making a well in the dry, pouring the wet in).

I was afraid the pancakes might taste of vinegar, but even my wife says they’re fine. No one complained.

Computer science, English, philosophy: what is a schema?

Tutoring academic subjects, meanings are so important. The tutor shares ideas about the meaning of schema.

a description of a particular subset of reality. The schema will include members of that reality and their properties. It will also include the relationships between them.

A schema might often be shown as a diagram, table or flowchart in order to express the relationships among its members.

A truly good schema will not only describe reality accurately, but will suggest possible relationships before they have even been realized. Hence, schemata (plural of schema) are used not only for teaching, but also for research.

Chemistry: what are degenerate orbitals?

Tutoring chemistry, you sometimes cover bonding. The tutor defines degenerate orbitals.

Degenerate: being two separate objects with a single, identical value.

The 1s orbitals of two separate hydrogen atoms are degenerate because, isolated from each other, they share a single, identical energy level.

When the two hydrogen atoms bond together, their separate 1s orbitals merge into two hybrids, one of high energy, the other low. There are still two orbitals, but each of unique energy level, so the degeneracy is erased.

Such is how I understand degenerate orbitals from the reading:)

Computer science: what is a hash function?

Tutoring computer science, you might be asked about hash functions. The tutor shares an idea about them.

hash function:a mapping of a large data set to a much smaller one that preserves a desired peculiarity of the original data. The input data may be of complex type such as objects, while the output may be a string or a set of integers (or, possibly, just a single integer).
An example of a hash function might be as follows: Suppose a restaurant’s reservations for tonight are five tables of four, ten of two, and a large party of eight. Describing that as reservations for 48, you’ve used a hash function.

Home computer use, English: bookmarks

Home computer use can lead to constant self-tutoring. The tutor reflects about bookmarks.

In The Road Not Taken, Robert Frost arrives at a fork where he must pick one road to travel. Looking down each as far as he can, he chooses the second. He then confides to the reader,

Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back.

An internet researcher faces much the same situation: one site can lead to another, then more may link from it. You might even visit a page but not read much of it, only to save it as a bookmark “for another day” – knowing, just like Frost intimates, that you’ll unlikely return.

Today I began looking through the bookmarks that I’ve accumulated on the main computer. I rediscover so many links to great sites that I recall finding, but didn’t follow up. Time is limited, and the topic that was urgent that day soon gave way to another.

On the internet, we’ve all joined the company of Robert Frost in a way perhaps unimaginable when he wrote The Road Not Taken circa 1915. With so many pages acting as nodes to groups of others, the internet surfer faces choice after choice, leaving by far most pages – and the ones that would follow – unexplored.

Calculator usage: changing angle mode on the Media SC-1000

Tutoring math, scientific calculators are always interesting. The tutor mentions changing between DEG and RAD mode on the Media SC-1000.

The Media SC-1000 is an appealing scientific calculator. I’ve been using it often during my sessions lately, having bought one years ago.

To move into RAD mode from DEGREE mode (or back the other way), do the following:

  1. Press the MODE CLR button twice, at which time you’ll hopefully see the choice for Deg, Rad, or Gra.
  2. Select which of Deg, Rad, or Gra you wish.
