Web design: color multiplication

Self-tutoring about color multiplication: the tutor looks at a method.

A way to define multiplication of two colors rgb(Ar,Ag,Ab)and rgb(Br,Bg,Bb) is rgb(Ar*Br/255,Ag*Bg/255,Ab*Bb/255).

For example rgb(100,100,100)*rgb(100,0,100)=rgb(39,0,39), seen as

color1*color2=color3

Strength training: synergy

Self-tutoring about strength training: the tutor makes an observation.

Like often, my son and I hit the gym after supper this evening: he’s a body builder. I wasn’t making any PRs tonight, but he did.

Perhaps someone else was trying for a PR: at one point I noticed a lifter had set a barbell totalling over 400 lbs. He began the lift: “AAAAAAAAAAAAAAAAAHHHHHHHHHHHHH!!!!!!!” Succeeding, he exclaimed, “Yeah, Baby!”

The others all continued what we were doing, setting new plates on bars, lifting, or whatever. Yet, the mood was uplifted. That dramatic PR elevated everyone.

I really love weight training because it’s a sport where all participants can win. Tonight, that new PR by a lifter I don’t even know made me feel triumphant as well.

Seasons: first day of Spring, 2019

Self-tutoring about weather and seasons: the tutor makes an annual report.

Back in my post on January 26, 2015, I define the first day of spring as the year’s first sunny day with positive double digit temperature. Since then I’ve reported its coming each year.

This year’s first day of spring, here in Campbell River, is today, March 16. The temp is 10.6C, and it’s dry outside.

Bird watching: chipping sparrow

Self-tutoring about birds: the tutor mentions an exciting observation.

To quote the Beatles, “it’s been a long cold … winter.” Yet, it may be letting go: last night’s low was +4C.

This morning indicated a change: in the dark, I heard birds outside. At first, I didn’t recognize what I was hearing. Yet, unmistakably, a robin’s song reached me.

I was so surprised to hear a bird so early, I went outside. The robin wasn’t alone; I could hear another song, an insistent trill.

I investigated the web and a book to discover the singer: a chipping sparrow.

The robin and chipping sparrow inspired me this morning, similarly with the varied thrush’s song I mention in my post from Feb 21.

English: “Minder”

Self-tutoring about English: the tutor reminisces, mentioning the term “minder”.

When I was a kid, I used to watch a British TV show called Minder. I’d say it wasn’t a comedy, yet was very funny. It was about a small-time crook who had a helper whose title was “Minder.”

The word minder, it turns out, is a noun that means “one who looks after something.”

Computer science: what is a search mask?

Self-tutoring about computer science terminology: the tutor mentions “search mask”.

As I understand:

search mask (n): a pattern that matches must follow. The masked parts are variable, possibly indicated by wildcards. An example might be qu#te, # being the wildcard. Such a mask will match “quote” as well as “quite”.

Cooking: temp to keep food warm?

Self-tutoring about cooking: the tutor mentions keeping cooked food warm in the oven.

Wanting to keep prepared food warm, I looked up a recommendation. One site mentions 200F. Covering the food with foil is recommended.

The chicken was already fully cooked. Therefore, I settled for 175F, 10F above its safe temperature.

Windows: command line: forfiles command

Self-tutoring about Windows cmd prompt: the tutor mentions the forfiles command.

I continue to use the command line when navigating Windows, likely because it seems quicker than the file explorer.

To find files in the current directory last modified on or after dd/mm/yyyy, one can try the forfiles command:

forfiles /d +dd/mm/yyyy /c “cmd /c echo @file @fdate”
