2 guys, or I'll 0 you both! 1?

[-] [email protected] 3 points 2 weeks ago

Why did 2 break up with zero?

Some 1 got between them!

If you count in binary you can get to 31 on one hand, and 2,047 on two hands

[-] [email protected] 14 points 2 weeks ago

I'm not flipping you off, i just counted to 4

19 is the rock and roll symbol

22 is the shocker

Assuming you use your thumb as the first bit

[-] [email protected] 12 points 2 weeks ago

I taught my kids how to do it and for a while they'd tell each other to binary four off

[-] [email protected] 8 points 2 weeks ago

My seven year old did something similar. At least once a day I'd hear 'Dad, Dad, I'm counting to four!' and see the little shit flipping me off and laughing hysterically :D

[-] [email protected] 7 points 2 weeks ago

It really turns into Naruto style ninjitsu.

[-] [email protected] 4 points 2 weeks ago

One hand would be 2**5 = 32 (0 to 31) and two would be 2**10 = 1024 (0 to 1023).

And if you use 3 states per finger (down, half raised and raised), you can have 3**10 = 59049 (0 to 59048).

[-] Cethin 2 points 2 weeks ago

I don't count to 1024 over often (literally never) so I don't feel the need to go to trinary.

[-] [email protected] 1 points 2 weeks ago

nah, you can have 16+8+4+2+1 = 31 on one hand, and 1024+512+256+128+64+32+16+8+4+2+1=2047 on two hands.

Nah. 1,2,4,8,16... or 1, 10, 100, 1000, 10000, depending on how you look at it.

[-] [email protected] 3 points 2 weeks ago

You use more than one finger at once.

[-] [email protected] 2 points 2 weeks ago

I don't know many people who count like ๐Ÿ‘โ˜๏ธ๐Ÿ–•, so you kinda already do. You're just allowing more combinations

[-] [email protected] 1 points 2 weeks ago

Good point.

[-] [email protected] 8 points 2 weeks ago

Someone is confusing indices and cardinality.

The French used to count in base 20 (so that means both hands and both feet), which is why they read 97 as quatre-vingt-dix-sept, ie 4*20+10+7.

[-] [email protected] 3 points 2 weeks ago

One of the reasons why I hate learning French so much.

[-] [email protected] 1 points 2 weeks ago

coworker taught me this and it blew my mind. I had previously jokingly used base 2 with my hands, but something like 01001 10010 would be difficult to handle.

[-] [email protected] 2 points 2 weeks ago* (last edited 2 weeks ago)

Base 2 should be easy to add, but it requires effort to convert

[-] [email protected] 1 points 2 weeks ago

It gets easier with practice

[-] [email protected] 1 points 2 weeks ago

Don't you mean base 10?

Also, clearly seximal is the best

[-] [email protected] 5 points 2 weeks ago

If you count finger joints and tips, using your thumb โ€“ you can count in hex (base16) on each hand.

[-] [email protected] 1 points 2 weeks ago

๐Ÿคฏ wow, that's a neat idea! That might come in handy some time ๐Ÿค”

[-] [email protected] 4 points 2 weeks ago

THERE ARE FOUR LIGHTS!

[-] [email protected] 4 points 2 weeks ago

"Please count to 10."

"... um, I've run out of fingers."

[-] [email protected] 2 points 2 weeks ago

You only need two fingers for that though

[-] [email protected] 3 points 2 weeks ago

Honestly, I count using the four fingers for 1-4, close the fingers and extend thumb for five, then extend each finger again for 6-9.

The right hand counts tens and works the same way. Can count to 100, and it's pretty intuitive. It's like if positional notation was discovered way earlier.

[-] [email protected] 2 points 2 weeks ago* (last edited 2 weeks ago)

0 1 10 11 100

[-] [email protected] 2 points 2 weeks ago

I've watched Inglorious Basterds I'm not falling for that trick

[-] [email protected] 2 points 2 weeks ago

0; 1; 2; 4; 8

[-] [email protected] 1 points 2 weeks ago

0, 1, 2, 3, 5, 8, 13, 21, etc.

[-] [email protected] 1 points 2 weeks ago

Fun fact: when learning some instruments (e.g. bowed instruments) you also number the fingers starting from your index (because you don't play with the thumb)

[-] [email protected] 1 points 2 weeks ago

LUN is life.

[-] [email protected] 1 points 2 weeks ago

I literally did this the other day... to be fair, it was a list starting with the number zero.

[-] [email protected] 1 points 2 weeks ago

Haaaaaang on is that why we start on 0...

[-] [email protected] 5 points 2 weeks ago

No. We count start at zero because the array already starts with an element of a specific size. Starting at 1 would always skip that initial element.

[-] [email protected] 8 points 2 weeks ago* (last edited 2 weeks ago)

You could have "empty arrays" in a language if you wanted. The real reason is that you start with an offset of zero as you read an array from memory at hardware level, and so this way address is just "start address + element size * element number".

[-] [email protected] 4 points 2 weeks ago* (last edited 2 weeks ago)

No, we start counting at one. We start indexing at zero.

An array with one element has an element count of 1, and that element would be at index 0.

[-] [email protected] 2 points 2 weeks ago

This is how we end up with off-by-one errors

[-] [email protected] 0 points 2 weeks ago

Because if you convert it back to binary, you have 0x0000 and that is one extra bit you can use instead of limiting your available values.

[-] [email protected] -2 points 2 weeks ago

AKschually, thumbs aren't fingers.
