Grapes to raisins: the condensation ratio

Tutoring math, all kinds of relationships might call out to you. The tutor brings up the water loss from grape to raisin.

According to one source, fresh grapes contain 1g fibre per 138g. According to another source, raisins contain 1g fibre per 40g.

Therefore, assuming the only loss from grape to raisin is water, 98g of 138g is lost as grapes become raisins. The percentage weight loss is 98/138 = 71%.

Neat, eh?

Home computer use, Microsoft Word: Thur or Thurs for Thursday

Tutoring business English, you might know of this preference of Word. The tutor shares a discovery about the abbreviation for Thursday.

A few days back, I was typing on Word 2016. Thur was marked as a misspell, but of course it was, I reasoned: Thursday is the true spelling.

However, Thurs passes unmarked on my copy of Word 2016.

I love discoveries like this:)

Calculator usage, math: logs in variable bases with the Casio fx-991ES PLUS C

Tutoring math, you come to appreciate calculators. The tutor points out an interesting feature on the Casio fx-991ES PLUS C.

English, Latin: what does sub rosa mean?

Tutoring English, I constantly await new vocabulary discoveries. The tutor shares the meaning of sub rosa.

sub rosa: (adverb) covertly; secretly

Sub rosa, in Latin, has the literal meaning “under the rose.” Roses carried the implication of confidentiality even in ancient times; a room might be stocked with roses before a meeting to remind attendees not to share what’s said there.

Home computer use: Windows 7 sleep modes

As a computer user, I’m constantly self-tutoring. The tutor shares about Windows 7 sleep modes.

I find my Windows 7 computer sometimes a bit groggy after it’s been idle for a while. This morning I began investigating it, and learned about sleep, hibernate, and hybrid sleep.

When a Windows 7 computer is left idle, it likely goes to sleep to save energy (and wear). How deep its sleep is determined by power options. Apparently, a computer can sleep, hibernate or hybrid sleep. The way I understand the three:

  • Sleep: open documents stored to RAM, but most processes suspended until user returns.
  • Hibernate: open documents stored to disk, then computer shuts off: power to RAM ceases.
  • Hybrid sleep: idle computer stores open documents to disk. Theoretically, the open documents are meant to be kept in RAM as well.

When a computer goes into hibernation, but is awakened, the previous state must be loaded from disk to RAM before it’s ready. This extra step can take extra time, apparently. However, hibernation offers extra protection against document loss due to power loss.

Lifestyle: strategies about making a peanut butter and jam (or jelly) sandwich

I definitely seek all the self-tutoring I can. The tutor shares some tips about making a peanut butter and jelly (or jam) sandwich.

Peanut butter and jam, or jelly, is a mainstay of our culture. How many hungry people depend on it when there’s no other plan? It’s actually quite nutritious, besides.

Here are a few tips for making a better one:

  1. Use bread that’s not terribly coarse and dry, yet not too soft either. Middle of the road bread is best, so that the sandwich is not too dry, yet not floppy.
  2. Spread peaunt butter inside both slices, then spread the jam (jelly) on top of it. Doing so will prevent the jam or jelly leaking through the bread.
  3. A smoother jam, or a jelly, might be a likely companion for crunchy peanut butter. Conversely, smooth peanut butter might go best with a fruity jam or preserve that offers more texture.

English: what does paucity mean?

Tutoring English, vocabulary is a perennial theme. The tutor mentions paucity.

Paucity refers to a situation in which the quantity or number of an item is small, likely smaller than expected.

Due to the paucity of cream in the fridge, we made tomato sauce [for the pasta] rather than cream sauce.

SEO: how to depersonalize search results on Google

Tutoring web marketing, you might come across the idea of personalized search. The tutor delves into the world of SEO.

SEO – search engine optimization – is, to my understanding, the tailoring of a website to gain search presence.

Since search results can alter depending on a device’s search history, the question can arise: “What do other people see when they type in that query?”

Of course, one way to do a search unprejudiced by your own history is to use a different device. Apparently, another way to depersonalize search on Google is as follows:

  1. Search the query on Google like normal.
  2. Then, at the end of the search string that is returned in the query box, type &pws=0.
  3. Press Enter to repeat the search, this time with depersonalized results.

English: what are ephemera?

Tutoring English, you always like to encounter new words. The tutor brings up the word ephemera.

If something is short-lived, it’s ephemeral.

CSS: What is oblique font-style?

Tutoring web design, oblique font-style comes up. The tutor shows it alongside italic.

Oblique is a font-style some people describe as similar to italic.

This is oblique font-style.

This is italic font-style.

Oblique seems to slant more than italic; I like its effect. One can imagine using both font-styles in a situation where text is emphasized for different reasons.
