A photo of a cake with 8 candles in a row. The first and fifth candle from the right are lit. The caption reads “Happy 17th Birthday”
I will grow older than 255 because then it will overflow and I become 0 years old.
I read 136 🤣
Look, an OpenRISC user.
Very optimistic to have an 8th candle
That’s the sign bit. The cake is in two’s complement
The candles are only available in packs of 8. It’s the smallest addressable unit of wax in many cake architectures
Maybe this is a signed cake, so one can celebrate negative birthdays of people who aren’t born yet. 🤔
Light all the candles as an announcement that you’re gonna start having kids and hope she’ll get pregnant in exactly three months. Not in 2, not in 4, but in 3 precisely.
You win Lemmy, I need this one explained.
Longer explanation:
Because most computers use two’s complement to make negative numbers. To produce -x, you take x, flip all the bits, and then add 1. Conveniently, this process works both ways, so if you have an
intwith a positive MSB, i.e.1*******, that’s a negative number, and if you invert and add 1, you get the positive number.So if you take
11111111, and apply this process, you get00000001, which equals 1. Thus,11111111= -1Secondly, the gestation period of humans is 9 months, and there are 12 months in a year.
So if you have binary candles and all of them lit, that can suggest, which it does in my previous comment, that you’re celebrating a child’s -1st birthday.
Last birthday party I was at I just wanted a nibble of cake but they told me I had to take one or more bites.
I’d have a few words with them, kick them right up their rear endian
Old man’s last words on his 256th birthday: “Unhandled IntegerU8OverflowException, terminating application.”
Why do I confuse Halloween and Christmas? Because Oct 31 is the same as Dec 25
Octal 31 = 3 x 81 + 1 x 80 = 24 + 1 = Decimal 25
- The Yuki language in California has an octal system because the speakers count using the spaces between their fingers rather than the fingers themselves.[2]
- The Pamean languages in Mexico also have an octal system, because some of their speakers “count the knuckles of the closed fist for each hand (excluding the thumb), so that two hands equals eight.”[3] https://en.wikipedia.org/wiki/Octal
Just curious since you seem knowledgeable, is there a connection between those societies? Or is it just chance they both choose 8?
Who counts from right to left?
Is this image mirrored?
Even in decimal, the most-significant digit is to the left. Binary in text form is no exception to this.
Unless we are talking little-endian, which would start with the least-significant bit.
Binary exists in both
big-endianLSb orlittle-endianMSb. In other words, both directions can be valid.As explained below: Endianness is specifically the order of bytes. I was under the impression that it also implied a specific order of bits but anyways, the correct terms for this discussion is Least/Most Significant bit order.
This is a single byte, so it’s represented the same in big-endian vs little-endian. Endianness defines the order of bytes, not individual bits
You will be surprised to hear that this is how we read decimal numbers too
We’re low on candles, great idea!
I hit the big 101000 recently. Time sure does fly by.
I use that style of birthday candle, but I only place as many bits as needed.
The year before adding a bit then has all candles lit, the next has only one lit
Though the new bits don’t come very often. My last was 31 to 32, my next will be 63 to 64, I don’t like my chances to see one after that
Heh I’ve been making my wife do this since my 32nd birthday.
She still doesn’t understand binary and thinks I’m a nerd when I try to explain it to her.
Maybe this year, when it’s 1+8+32, things will click.
Happy 136th birthday
Little-endian for the win!
Even in little endian you don’t have trailing zeroes
I’m not seeing any trailing zeros if that is in little endian, you start little end first and it isn’t limited to a silly 8-bits, it can be used to represent numbers far larger than 255 if continued (though then it wouldn’t be representative of a byte and half the joke would be lost).
If you read from the right (as is implied by calling the result 17), there are 3 trailing zeroes:
These would usually be omitted when writing like this. The fact they are not makes this 136
I think you missed the point, that I was making, albeit poorly (little endian still requires leading zeros when not transmitting in a byte format, otherwise you don’t know if the first on signal is for 1, 256, 1024, etc.) it’s all good though
How would 3 leading zeros in a byte help coming to the conclusion that this is supposed to be 17?
I’m generally curious, sice theoretical informatics is already a good few years behind me :D
In a normal byte format it wouldn’t help, the byte standard breaks off bits into 8 bit chunks and calls them bytes (I’m not trying to explain basics, just putting it there for background), little-endian excels at using the least number of bits to express larger numbers in a stream. If you wanted to send any number from 0-255 you only need 1 byte, for 256-512 you need two bytes (or 16 bits), in little-endian it can be represented in just 9 bits, or up to 1024 in 10 bits, etc.
Doesn’t matter for much to many people, but when the number gets big enough you can save a lot of bandwidth.
Related: I once got onto my feed a post of a tale of someone who had a child on his 19th birthday, so for his 20th birthday, and the child’s 1st, they had two balloons celebrating their 20th birthdays.
Instructions unclear… Am vampire now.
I’d actually quite like an overflowing cake thank you very much
33 was a special year for me because it’s the same forwards and backwards both in decimal and binary
1 is asswell :3
If 1 is asswell, then 2 is assgood, and 3 is the beginning of an orgy.
00100001
Am I being dumb? How ist that the same forward and backwards?
