In real life, you may get 255 wishes, or you msy get (-1) wish, and have to perform one wish for the genie.

[MoonGlow]

Genie: You have 3 wishes
Programmer: I wish for 0 wishes left
Genie: Granted, now you have 3 wishes
Programmer: Damn it, wish count is stored as 2 bit unsigned int

[javoresku]

Well that must be an old 8-bit genie. Imagine if it was a 32 bit genie...

[Bluexx]

Genie: "You have 3 wishes, you know the rules"
Me: I wish for 0 wishes
Genie: "Really? ...Ok, I will not grant any of your wishes. Have a good day."
Me: ... Crap. They patched the exploit.

[MichaelPiz]

Just thought of a way around the "no wishing for more wishes" rule: wish for more genies.

[trchri]

Wife: Get a loaf of bread; and if they have eggs, get a dozen.
Programmer returns with a dozen loaves of bread.

[evanrosman]

I might make 2 regular wishes first just incase.

[aaronbredon]

This fails if wishes are predecrement (--wishes_left, grant wish)

Genie: you have 3 wishes
Programmer: I wish for 0 wishes left
Genie: (decreases wishes left to 2, then grants wish, setting wishes left to 0)
Genie: your wish is granted. You have 0 wishes left. All your wishes have been used. Goodbye.

One of my fave t-shirts, "There are 10 types of people in the world, those who know binary and those who don't."

[IanHsieh]

Next joke: Why would a programmer get confused with Halloween and Christmas?

That easy to achieve.
1. wish: Count the wishes in an 8-bit unsigned integer variable.
2. wish: Let set the wish counter to 0.

Genie: I'm not signed for this.

And now we just created the brand new Genie programing language. 🤣

[UserJ]

This is why you decrement the variable first then grant the wish, wishes become 2 then 0.

[Makememesandmore]

I like that he created an 8 minute video to explain a joke and still managed to turn it into a useful lesson

[paulowen]

Don't ask for NULL wishes, you may crash the genie.

[Ostap]

Any experienced genie would decrease left wishes before granting the wish. It must have been a junior developer probably.

[smilerbob]

I just found a magic lamp and tried this on the Genie…

The Genie muttered something about a buffer underrun and stopped responding 🤷🏻‍♂️

[ЭролСезгин]

I remember this genie programmer joke:
-Genie: you have 3 wishes
-Programmer:

1.do the opposite of my next wish,
2.don’t fulfil my third wish,
3.ignore my first wish
-- critical error

[berndschneider]

Actual overflow in Civilization I: Treasury jumps from 32767 to 0. I can hear myself swearing still today.

[robliversage]

As far as I'm aware all genies are 2-bit having a maximum of 3 wishes.

[atlas]

Just hope the genie programming language uses wraparound overflow errors and doesn’t just spit out “error overflow line 13”
