Try to keep it practical (like something that would be fairly doable, you just havent gotten around to it…yet)
There are apps that you can input text into and they can replace the characters in each word incrementally to help learn them. Wanna get into that
Multiplication table… One day I’ll get those 7s and 8s.
(I’m 40).
U know what you’ve done
How to do almost anything by hand, and the phonetic alphabet (specifically nato phonetic alphabet) can be useful for misunderstandings. I want to learn shavian, an alphabet optimized for english, just for fun.
Have a great day, be kind, and have fun! :D
The NATO alphabet comes in handy sometimes
Pretty much how to do any task without electricity or a device that depends on it. It can be really useful to know how people did every day stuff 200 years ago.
Do you know how to do your laundry without a machine? Use a map? Send mail via post?
The first 100 digits of pi lol. On a more serious note, it is very useful to remember how you should react to certain comments you know others will make in the future.
Can you talk more about that last part
Your state’s mental hygiene/commitment laws and the Convention on the Rights of Persons with Disabilities treaty that U.S.A. is the only country not to ratify.
Fa Do Sol Ré La Mi Si
(F…C…G…D…A…E…B)this is the order in which sharps go. Gives you the tonality of a given song. Let’s say the song takes 4 sharps- take the last one (Ré/D), add a half-tone to it (Mi/E), there it is, your song is in E major
It works with flats as well, in the reverse order (Si Mi La Ré Sol Do Fa). Take the next-to-last flat, that is your tonality.
That’s cool!
I don’t understand any of it. (ELI5 please? Thanks for sharing this anyway!)
Have a great day, be kind, and thanks for sharing! :D
Phone numbers of your life partner, parents, children, siblings and a lawyer.
My credit card number and associated details.
Nah thats what password managers and physical custody of the cards are for
It came in handy when paying for parking today.
You didnt have your phone or the physical card on you?
well, give it then
7569… Wait a minute!
If you cook, bake, brew, anything with food and drink.
Common volume conversions: 3 teaspoons in a tablespoon, 4 tablespoons/2 fluid ounces in a quarter cup, 8 fluid ounces in a cup, 2 cups in a pint, 2 pints in a quart, 4 quarts in a gallon.
Common weight conversions: 28 grams in an ounce, 16 ounces in a pound, 2 pounds and 3(ish) ounces in a kilo.
And common volume to weight conversions based on ingredients you use. For me: 200 grams in a cup of sugar, 125 grams in a cup of AP flour, 6 grams in a tablespoon of cocoa powder.
Makes it a lot easier to halve/double recipes, or use a scale for a volume written recipe.
Thank you but as the solar system as my witness that is such an absolutely terrible way to keep track of quantities
What a headache, as a non-American just reading this makes my frontal lobe hurt.
The standardized NATO phonetic alphabet
…for when you need to read alpha numeric codes or clarify spellings.
Especially with, how, inexplicably, phone connections seem to have gotten more garbly in recent years.
This code was invented to be reasonably understood as much as possible in less-than-ideal communication conditions.
As time goes on, civilian life is full of situations where you’ll need to read off serial numbers, codes, or even spelling your own name, to somebody seemingly connected to you from a million miles away via coconuts and twine.
So, learn it, and you never need to go “M as in…uh…‘Mancy’?” ever again! Your IT department might thank you.
…and let’s be honest, it sounds kinda cool. :)
First names still haven’t let me down to this date, and I’ve done phone work in the past.
I agree that this has been very useful for me. Initially taught it to myself when I was working in IT, and it has come in handy a lot.
More garbly? That’s those hosers using built in laptop microphones or speakerphones. Terrible.
Oh definitely! If there’s one thing I’m done with, it’s people calling on speakerphone while their phone is like, seemingly, in their gym bag in the trunk LOL.
Like bro, you’re not Jack Bauer and I’m not your handler, it can wait until you’re done going 75 on the freeway.
Maybe my work’s phone network service is just awful, even landline to landline, but yeah, for how much faster data connections have gotten, I feel like I got clearer voice quality on my cordless Vtech in 2004 LOL.
Maybe it’s me and I should get my hearing checked. 😅
Your wife’s birthday?
How to convert various units of measurement. (Including between imperial and metric.)
2.54 centimeters in an inch. Degrees Fahrenheit is nine fifths of degrees Celsius plus 32. Stuff like that.
The dimensions of the doorways in my house.
No excuse
Converting between hexadecimal and binary. It’s not that hard and it would’ve been useful many times, but I still haven’t memorised it
If your a software engineer, memorizing an ASCII table (particularly the hex numbers of each character code) is definitely helpful. If for no other reason than so that you can read things that are randomly written in binary without having to consult a table.
Something not really otherwise terribly useful that nonetheless helped me keep my sanity: learn how to convert to base64 in your head. At work, we had really boring 8-hours-a-day training for a couple of weeks. To pass the time, I came up with random strings to base64 encode in my head. “
Hatis48 61 7a. The first six bits are010010which in base64 is anS. The next six bits would be000110which in base64 isG.” Etc. I’d write down the base64 strings character by character as I derived them and then check my results for errors when I got back to my desk.What is there to memorize about it? The 16 binary values? What is that useful for?
When is it useful past the point of just looking it up as need be?
It’s not something you try to recite. You just do it so many times you became too good at it to look at the table.
Four bits can represent up to 15, from 0000 to 1111. Correspondingly, 0 to F in hex.
Binary from right to left is 1, 2, 4, 8.
One byte is eight bits. It takes eight digit places.
XXXX XXXX0000 0000 to 1111 1111
00 to FF
0 to 255I mean when would it be so necessary that it jystifies itself or the time cost to do so
It’s useful if you’re a network engineer or a web designer.
Sub netting baby!
