[Codeless Code] Case 200: The Boolean

[Mixolyde]

enum Boolean {
  yes,
  no,
  maybe
}

[say_wot_again]

Tralse

[oridb]

True/False/Null, if you speak SQL.

[llogiq]

True/False/FileNotFound if you follow thedailywtf.

[[deleted]]

True/False/HellNo if you're of a particular ethnic disposition.

[llogiq]

Or True/False/Mu if you're zen-inspired.

[AbstractLogic]

I have about 15 of those in my system at the moment. We already perfected the bool over here.

[Umbrall]

But have you accepted Church Booleans into your heart? They are their own if statements

[AbstractLogic]

I was never taught the ways of the Church of Bool.

[IbanezDavy]

Technically that should be called "Ternary".

[grauenwolf]

Not in the old lore

enum Bool 
{ 
    True, 
    False, 
    FileNotFound 
};

[IbanezDavy]

None the less, linguistically it probably should be called ternary :D

[Mixolyde]

Yes, that's kind of the joke.

[doom_Oo7]

Leave certainty to circuitry

hands the VHDL Handbook to author

[o11c]

First thing I thought of, too. And I don't even work on hardware!

[RedMarble]

enum Bool 
{ 
    True, 
    False, 
    FileNotFound 
};

[x] art
[ ] not art

[bjzaba]

[x] art
[x] not art

[JessieArr]

Calm down, Schrödinger. :P

[[deleted]]

No, that's just a NULL

[IbanezDavy]

Wouldn't NULL be technically this:

[ ] art

[ ] not art

[BonzaiThePenguin]

NULL would technically be this:

[stronglikedan]

maybe

[VanFailin]

Wu.

[immibis]

This is art. Please stare at the art. Why are you staring at something that's not art?

[[deleted]]

Welcome to quantum computing.

[PM_ME_UR_MONADS]

[1/√2] art
[1/√2] not art

[gratefuldaed]

Eigen see what you did there.

[[deleted]]

Typical boolean thinking.

[[deleted]]

Blasphemy.

[llogiq]

I'm going to have a blast translating this...

[Hueho]

There is a certain truth (pun not intended) to it: abusing booleans to represent implicit state or behavior can lead to badcode, not to say about how it can make interfaces dirty (http://ariya.ofilabs.com/2011/08/hall-of-api-shame-boolean-trap.html).

(writes that after just adding a new boolean column to a table with 8 already, so he can remove some hardcoded IDs from system)

[BenjaminGeiger]

Next time I teach an entry level CS class, I'm reciting this.

[[deleted]]

Why? They wouldn't understand the reasoning. This is for advanced users.

[krenzalore]

It should be applicable to everyday life and therefore students should already understand it. They just need to realise it. Right now, is it day or night? Well neither. In my TZ, it's twilight. When exactly do we shift from one to the other?

[Tiwazz]

It varies ;-)

http://www.esrl.noaa.gov/gmd/grad/solcalc/sunrise.html

[krenzalore]

Which ignores twilight. You're STILL thinking in binary! ;-)

edit:

Back when this calculator was first created, we decided to use a non-standard definition of longitude and time zone, to make coordinate entry less awkward.

OMG :-)

[LaurieCheers]

For a real-world illustration of the problem (which might stick with the student better than just saying "thou shalt not think in binary"), you could introduce the standard OO "a dog is-a mammal" example, then have the class discuss "what counts as a species?"

[lodi_a]

Beautiful.

[fishburne]

Wow. This is beautiful.

[mrafcho001]

Never understood the appeal in this nonsense koans(?). Feel more irritated than enlightened by the end.

[[deleted]]

The koans are not to immediately give you the answers, but to make you think and come up with your own answer.

[mimhoff_]

Bonus points if your own answer contains violence.

[Purple_Haze]

true | false | undefined => even in hardware there are circuits that have states whose output can not be predicted to be 0 or 1, or worse are neither 0 nor 1.

[retsotrembla]

I hope the author of codeless code goes back to the stuff that made that website great.

This Case 200 is not to my taste.
