Clearly your gender field is a boolean. Which means it can be either true, false, null, or undefined. Except in javascript where for some reason it can sometimes be NaN, but only when you try to compare two people.
My gender is
{ toString: ()=>{String.prototype.toString = ()=>">:3"; return ":3";} }A boolean, so 8 bits of freedom to fill up
Even booleans take up 8 bits. And that’s a lot of wasted space.
That’s only due to technical reasons on weird platforms like x86, 64bit x86 or ARM.
That’s why you use bitarrays and bitflags instead when you need more than just one or two arguments for a function.
Only if it’s performance sensitive. Otherwise you’re wasting programmer time both writing and reading the code, and you’ve made it less maintainable with more complexities where bugs can creep in.
The vast majority of the time you can afford a few wasted bits.
Honestly though I don’t quite understand why a compiler couldn’t optimise this process. Like it knows what a boolean is, surely it could reduce them down to bits.
Well, to get a boolean out of a bit array you have to do some operations. So at first it doesn’t make it more performant. Compilers probably don’t automatically make them bitarrays because of that.
However, the memory savings means less cache used. And a cache miss is way more expensive than those bit operations. So they should be more performant. I’m sure someone out there has done the actual research and there’s a good reason why compilers don’t make all booleans bitarrays.
Solution: 1 bit computer
Bold of programmers to assume gender can be expressed accurately in a finite discrete system. Gonna have to bust the Taylor series for some better approximation.
My gender is a null-pointer.
Gender is a pointer
Now is the time for quantum computing
Why not a linked list? Or a hash-table?
Gender: true
isMale
import isFemale def isMale(Person): if isFemale(Person): return False else: return Truepublic boolean isMale() { return !isFemale(); } public boolean isFemale() { return !isMale(); }StackOverflowException was unhanded
Gender is a second order tensor, so you should store it as a pointer to an array of pointers for maximum read/write speed.
Gender is obviously a signed byte.
Gender is a struct
struct Gender { byte binaryBias; ///Determines male (+) or female (-) bias if present ubyte binaryAm; ///Determines the amount of binary gender(s) present bool isTrans; ///True if assigned at birth gender does not equal with current one ubyte xenoAm; ///Determines the amount of xenogender uint xenoGen; ///Xenogender selection, 0 if not applicable Sex* sex; ///Pointer to the person's current sex }Now this is a gender definition I can get behind. None of that string/enum crap, just raw data.
That’s a lot of implementation detail. Is there just a service interface I can inject to know what bathroom a person’s RFID fob should open?
Just don’t have gendered bathrooms, simple as that.
