The tutor asks, “How much weight loss, theoretically, might I realize from giving up cream in my coffee?”
It seems I’ve been served with a high cholesterol warning: likely, I should bring it down. With saturated fat being implicated as a potential cause of high cholesterol, the cream in my coffee gains attention. It’s got 1.5g of fat per Tbsp, 1g of which is saturated. Although I’ve not been told directly, I’m probably best to give it up: I already have.
Let’s imagine I use(d) 1 Tbsp cream per cup of coffee. Commonly, I drink 8 cups of coffee per day, so would use 8 Tbsp cream, each of which is 20 calories. That’s 160 calories per day, and 160*365=58400 calories per year. One pound of fat is about 3500 calories, so the 58400 calories could translate to around 58400/3500 = 16.7 pounds. I might, theoretically, “lose” 16.7 pounds per year by stopping using cream in my coffee.
While I’ve given it up, I loved having cream in my coffee.
The tutor offers clarification about what a definition does.
Often, in an English essay, the writer might need to define a term. From a working point of view, what does a definition do?
According to Harbrace1, a definition gives similar concepts (or nouns) to the one being defined, afterwards explaining how the term of interest is different from the other similar ones.
A desktop computer is similar to other devices of web communication, such as smartphones and laptops. A typical difference between the desktop computer and the other devices is that a desktop computer has a separate keyboard.

When I started with computers, I don’t believe you could have a folder name like this folder: as I recall, you couldn’t have a space in the name. (You could have an underscore as in this_folder).
I don’t know for sure, but I’d say Windows opened up the possibility of having a space in the name of a folder (or file). Nowadays, on people’s desktops, you commonly see folders with two-or-more word names, such as Road Trip Summer 2016 or Kitchen Reno. (I wonder if anyone else realizes what computer users seem to take for granted:)
On the desktop, two-word names don’t matter: you can just double-click the folder to open it. In the terminal, though, you need to type the folder (aka directory) name to enter it. Will the terminal know what you mean when you type a folder name that contains a space?
The terminal (aka, Command Prompt) in Windows 7 does understand a two-word name. For instance, if you want to enter the Kitchen Reno directory, just typing
cd Kitchen Reno
In the Linux terminal, from my experience, the command
cd Kitchen Reno
won’t work. However, you’ve got two options that will:
Null, it seems, is often mentioned in computer science. Perhaps it’s used a little loosely: it might refer to the value read when there’s nothing there, or the value of a variable that doesn’t exist.
A variable that doesn’t exist at all is of type undefined. Trying to print its value will prevent the script from running.
A variable that is declared but not given a value (eg var var1;) is also type undefined. However, the program will print its value as undefined.
A variable declared with a value null (eg var var1 = null;) is of type object. Its value will print out null.
The tutor shares a find he made in the new Microsoft Services Agreement, effective Sept. 15, 2016, relating to work or school accounts.
Although I use a lot of open source software, I’m a fan of Microsoft. There are some technologies of theirs I’ve always admired (VML, for instance: see my posts about it here). The computer I’m writing from this moment runs Windows 7. Years ago I started a Hotmail account. I suppose now, it’s become an Outlook.com account: that’s where I’m sent when I sign in.
Somehow, it seems, virtually everyone uses Microsoft products or services. Therefore, Microsoft might feel a need to countenance issues reaching beyond mere software. Perhaps an interesting example is the Work or School paragraph (4b of Microsoft Services Agreement, effective September 15,2016).
In that paragraph, Microsoft suggests that if a person signs into a Microsoft service with a school or work email, the owner of that (school or work) domain may access said person’s data. In an email about updates to the terms of service, Microsoft indeed suggests that account holders pay attention to clarifications about work or school accounts.
The meaning of paragraph 4b, like so many legal communications, might well be interpreted differently among readers. To me, it cautions that if you sign into your Microsoft account from a school or work email address, the administration of that school or work has the right to access the contents of said Microsoft account. Perhaps it’s not meant that way, but to me, that’s how it reads.
I wonder how many people have read that paragraph, and what their conclusions are?
The tutor shares the answer to a question he’s long harboured.
Generally, red oak acorns take two years to mature. Does that mean the tree drops a crop of acorns only every second year?
According to Cathy Blumig of outdoorlife.com, red oaks flower every year. Therefore, they certainly can produce acorns every year: this fall’s acorns will be from the flowers of sixteen months ago, rather than from the recent spring. Next year’s acorns, in turn, will be from this spring’s flowers.
While the quantity of acorns from a red oak may vary from year to year, the tree can definitely produce them every year.
The tutor researches the effects of juglone from black walnut trees.
Juglone is a toxin produced by the black walnut tree; it’s found throughout the tree and in its leaves, shells and nuts.
Apparently, to humans eating the walnuts, the juglone is not a problem. However, it enters the soil from the roots of the black walnut tree, as well as from its leaves, twigs, and even pollen falling to the ground – not to mention the nuts and their shells. Some plants, such as tomatoes, potatoes, lilacs, and rhododendrons, can be damaged by the juglone.
To be safe, composted matter from black walnut should wait a year or more before application.
Horses are particularly sensitive to juglone; neither black walnut shavings, nor the husk fibre, etc, should be used in a horse’s environment.
