A color-managed Linux workflow
Excerpt: if you have a color profile for your monitor, copy it to a folder with public access, such as ~/.local/share/color/icc.
Make sure you have ArgyllCMS installed, or at least the dispwin executable.
Then use this command to create a startup application entry that sets the profile automatically:

The Camp Fire, 11/8/2018, 8:17 a.m. looking over the ridge toward Paradise and Concow. The fire had started at 6:29 a.m. seven miles north of town, and when this picture was taken, Paradise was already evacuating.
8:40 p.m.; the fire topped the ridge about a mile away and started down the hill toward us. Evacuated shortly thereafter.

Watching an eclipse during the hour-plus between first contact and totality is like watching the minute hand of a clock; there is not much visible movement. Until the very end when the crescent gets down to about the last 1/6 of the sun’s circumference; at that point it shrinks before your very eyes until it disappears as if being swallowed up. With bated breath you take off your solar glasses, and hanging in the sky is an object of otherworldly grandeur. You sort of knew what to expect, but could not have imagined this. Amid a groundswell of oohs, aahs, and astonished whoas, you stare at it with your mouth open.
Everyone who has seen the corona says photographs do not do it justice. When you see it for yourself you know what they mean. It looks almost fluffy, three-dimensional, with a black disk stamped into it. It has lots of fine detail and gradation as if made of mother-of-pearl. This against the dark royal blue sky gives it a glowing jewel-like appearance.
Experienced eclipse chasers say not to photograph your first eclipse; just watch it and let it sink in. After 15 or 20 seconds I couldn’t stand it and tried to get a few pictures. Watching, fiddling with the camera, watching again; then, inexorably, the diamond ring reappears and it’s all over. Time to put the glasses back on. A number of people clap as if to praise a fine performance. It was the shortest minute and fifty seconds of my life. One more item checked off of the bucket list.

First contact at 09:08
Totality at 10:21, duration 1:50

A curmudgeon’s guide to grammar and usage
Short-lived rhymes with long-knived.
If you are short of hands, you are short-handed. If you are short of wind, you are short-winded. If you are short of life, you are short-lived. Think about it . . . .
A page that says “This page intentionally left blank” is no longer blank.
Data is the plural of datum. It’s something like facts. “These data show . . . .”
Media is the plural of medium. “Back up your files on another medium.” “Insert a blank medium.”
Criteria is the plural of criterion. “The first criterion . . . .”
Kudos (κῦδος) is the Greek word for “praise” and is singular. There is no such thing as a kudo.
Less refers to a continuous quantity; fewer refers to a discrete number. If you are on a diet, eat fewer cookies and drink less milk.
One thing is centered on another; nothing is centered around anything. The center is a point.
Pitiful means full of pity, as joyful means full of joy.
Something that arouses pity is piteous, or pitiable.
Nauseous means causing nausea, something like hideous.
When you feel nausea, you are nauseated.
Mischievous has three syllables and is pronounced “MIS-che-vus.” It comes from the word mischief.
“Mis-CHEE-vee-us” is not a word.
It is you; it is I. It is you and I.
It is for you; it is for me. It is for you and me.
It is with you and me. It is between you and me.
Always and forever.
Things differ from each other.
“This differs from that.” “This is different from that.” Similar to, different from; it all makes sense.
Practice saying it: “different from; different from; different from.”
(Side note: if you are comparing things that differ from something else, you might say, “this is more different than that is.”)
None is short for “not one” and is singular.
“None is left,” not “none are left.”
“None of the members is left,” not “none of the members are left.”
Sure, you can use a plural verb. You can also use “ain’t” in your resume and call your boss a geek. It’s a free country.
In defense of the “Oxford comma”:
What do you indolent, stuporous people have against a fricking comma? Leaving it out can completely change the meaning of a sentence.
“Last night I met two prostitutes, your mother and your sister.”
“Last night I met two prostitutes, your mother, and your sister.”
“I feel badly” means that when you try to identify something by touch, you do a poor job.
“I feel bad” means that you are experiencing distress. It’s like “I look bad” or “I am bad.”
Apostrophes that look wrong but aren’t: the plurals of non-words use apostrophes to prevent ambiguity.
“Mind your p’s and q’s.” “The 1930’s were difficult years.”
Some people disagree with this. I feel bad for them.
There is nothing wrong with using first person in formal writing. Third-person circumlocutions like “this writer” get tiresome very fast and should die.
Similarly, using myself as a way to avoid saying I or me is usually just plain wrong.
I tell it like it is.
