An elderly couple had just learned how to send text messages on their cell phones. The wife was a romantic type and the husband was more of a no-nonsense guy. One afternoon the wife went out to meet a friend for coffee. She decided to send her husband a romantic text message and she wrote:
If you are sleeping, send me your dreams.
If you are laughing, send me your smile.
If you are eating, send me a bite.
If you are drinking, send me a sip.
If you are crying, send me your tears.
I love you.
The husband texted back to her: "I'm on the toilet. Please advise!

Thanks for a good laugh Mike

Glad you enjoyed it Espen.
It gave me a good chuckle when I read it and thought it would be a good share.

Simplify (x & ~y) > (~x & y)
I quite liked how it just works out, and it's a nice little puzzle assuming you haven't seen it before, not so hard that it'll cost you your weekend, but good enough to tease your brain for a couple of minutes.
The comparison can be taken as signed or unsigned.
ps: I actually needed this thing today, but the other way around. I had to compute what this thing simplifies to, but only had x & ~y and ~x & y available.

Yes. Full points awarded.

Let x = 10, y = 20
Then
~y = -21
~x = -11
(x & ~y) = 10 & -21
(~x & y) = -11 & 20
Then perform bitwise operation  , Refer - Bit wise operations in C#[^]
Thanks,

Ok, but that's not a simplification.

True. Unfortunately you are shifting every bit of my brain nerves 
|
|
|
|
|
You could try picking values for x and y until you see a pattern..
Do you want a hint?
|
|
|

You should have specified the field here. Mathematical ~ means a bit different. Where's the not impressed icon?

Since it doesn't make sense if interpreted that way, it's not really ambiguous.
|
|
|
|
|
Yes, it does not make any sense when looked that way. It also may not make any sense in a rare programming language that treats ~ as declaration symbol and & as = symbol. It would be a really stupid language BTW.
Like you guys say, just my 2 cents.

It could be simplified to x > y
How this works:
Let's take two random numbers for x and y:
x = 37 = 00100101
y = 203 = 11001011
The values for ~x and ~y:
~x = 11011010
~y = 00110100
And the values for (x & ~y) and (~x & y)
x & ~y = 00100101 & 00110100 = 00100100 = 36
~x & y = 11011010 & 11001011 = 11001010 = 202
In this case, x and y are both substracted with 1. That's not always the case, but if you try this with other numbers, you'll see that x and y are always substracted with the same number.

Take a +5.
Out of curiosity, how did you do it? Or did you already know?

Ok, now it works (I caught your post just between edits).
Fun fact: that number is exactly x & y, and the general proof is
(x & ~y) > (~x & y)
// rewrite the & to a subtraction
(x - (x & y)) > (y - (y & x))
// subtracting the same thing on both sides doesn't change the order
x > y

+5! Nice general proof!

Imagine, if you will, a small, very dense star of a type known as a white dwarf. Imagine this star orbiting a much larger companion star, syphoning off its companion's gas and claiming it as its own. Imagine the dwarf gaining so much new mass that it reignites its thermonuclear furnace[^], blowing up in an explosion so bright that it will, briefly, outshine the whole galaxy. Imagine this light traveling for millions of years, until it reaches a tiny speck orbiting an ordinary star in the backwaters of another galaxy.
Or, you can just see it[^].
(Edit: renamed, so as not to be confused with an earlier post on a different topic.)

Yeah, its good picture but that little bright star is already gone, and you start thinking would it be someone to see when our "little" star explodes and photograph it.

Yeah, our little star isn't going to explode. Not enough mass.
It'll just become a red giant for a bit before it puffs off layer after layer of material. All fusion will eventually stop and it'll become a white dwarf....in about 4 billion years.
