Two spaces make sense on a typewriter. It allows you to see more easily that there’s the end of a sentence. On a computer, it’s unnecessary because the display software can determine it’s the end of a sentence and just add a bit more white space to represent the single white character. Also, in early computer systems all those extra space characters took up precious screen and disk space.
The underlining rule is that 1) text with fixed-width characters need to have one space between words and two spaces after sentence-ending periods. And 2) text done with variable-width characters and typesetting should let the typesetter determine the spacing everywhere.
For a typist on a typewriter, there’s no typesetting except what they are doing as they type. The spacing is exactly what is typed.
For someone entering text into computer file that is going to be typeset, the spaces simply demark the words. The typesetter will determine how wide the spaces will be when printed. Not only the widths of the spaces after a sentence-ending periods, but also the widths of the spaces between words. Entering more space characters doesn’t change that.
Kerning, right?
That, too. Kerning is the distance between the letters in the same word.
I’m always pleasantly surprised when the general public knows typographic terms… like “keming”.
.
eta: that does not say “kerning”…
I used to be a pen/ink draftsman. Did a LOT of Leroy lettering. That’s probably where I picked it up.
Not XKCD?
I got an email from our IT department. They have been testing us for phishing and have signed us up for security awareness training. Today I got an email with a link for security training. I was wondering if this could be another attempt to test us, and whether I should check with IT to see if it’s legitimate. Then they sent us another email to let us know that the training email is legit, so it seems I’m not the only one who thought that. 
Knowing my district, that second one would be the phishing attack.
You too? It didn’t help that the training came out of the blue from a company we had never heard from - with a l33t sort of name.
Oh, yeah - I’ve taken to reporting everything with a link on it as phishing.
Gotta amuse myself somehow.
We have a “Report possible phishing attempt” button in our email client. And IT routinely sends us test phishing emails to make sure we report them. I always, always, always report emails about security training as possible phishing as well. IT does not find this amusing, but I certainly do.
Our outfit does it too. Sends fake phishing. Drives me nuts. I’d really rather not have additional BS in my inbox.
We already have a company that weeds all that crap out. If it looks weird, it’s from our own IT Department.
Very minor rant: my password is expiring! Every six months my main password changes. I get EXTREMELY used to it. It will eff me up for weeks. Argh.
You really only need to create a handful of unique passwords. For example, Mother’s_Name/current_calendar_year/Mother’s_Birth_date would be DearOldMom202312251941, while Father’s_Name/current_calendar_year/Father’s_Birth_date would be DearOldDad202310311941. The next time you need to change it, switch the 2023 for 2024
I actually do have a scheme like that! But I will still type the wrong one out of habit, usually 2 or 3 times before I realize I it’s supposed to be the new one.
We are having a baby shower at our office for a woman (Abby) who expressed that she did not want one. Her manager (Becky) arranged it. Except Becky was going on vacation so she sent an email to the staff saying to coordinate with Carla. Carla was not asked if she would take this on, nor is she an employee of Becky’s, or even particularly close to Abby. But Carla has gone ahead and set things up, including spending her own money on snacks.
Carla is to much of a pushover so I’m going to tell Becky to pay her back.
Every six months?! I have one work password that expires every 60 days, and another that expires every 45 days. I have enough trouble remembering which one to use when, and then it takes me about a week to get used to using a new password after I’ve changed one.
One thing I’ve found that helps: I do my password changes on a Monday morning, that way I’ve got a whole week to use it and let it sink in. I got screwed one too many times changing my password on a Thursday or Friday and then forgetting it by Monday.
Most at our firm expire every thirty days ,except for the ones that don’t. I too have trouble remembering one the next Monday morning.
I said it was a minor rant! 
And the thing with six months is that it’s very much muscle memory, and I have to enter it whenever the computer goes to sleep.
