Why does it have String and str type?
Why do you need to specify -> return-type instead of just having the return type after closing ) and ) { meaning void?
If you are defining fields in the struct declaration why do you need specify fn for the new in the implementation?

>>61059104
String is a variable length string, &str is a reference to a fixed size array of chars.

And let is needed because denoting initialization from declaration is useful to both scoping flexibility (which is important in a RAII language) and compiler optimization.

String is the dynamic heap string type, like Vec: use it when you need to own or modify your string data. (It is the replacement for the old ~str type, which has now been removed.)

str is now just always a (immutable1) sequence of UTF-8 bytes (of unknown length) somewhere in memory. Since the size is unknown, one can only handle it behind a pointer, meaning that str most commonly2 appears as &str: a reference to some UTF-8 data, normally called a "slice". A slice is just a view onto some data, and that data can be anywhere, e.g.

in static storage: a string literal "foo" is a &str, where the data is hardcoded into the executable and loaded into memory when the program runs.
inside a heap allocated String: String dereferences to a &str view of the String's data.

> Why does it have String and str type?
The same reason C++ has std::string, std::string_view and char* - one own the string, and other doesn't.
> Why do you need to specify -> return-type instead of just having the return type after closing ) and ) { meaning void?
I have no idea why -> is needed, but you can omit it and it means (), i.e. void.
> If you are defining fields in the struct declaration why do you need specify fn for the new in the implementation?
I don't understand the question, are you talking about fields not being public by default? Because you can use put `pub` in front to make them.
> Why is there million lets
Because this is not an assignment but a declaration. The same reason you need to write `int` in `int a = 10;` in C.
> and why do they need = after let, shouldn't it be pretty obivious that value comes after symbolname?

Property is indeed theft and I can prove it.
As an example let's consider the case of food.
Let a thing belong to you if and only if you've earned it.
A food is, of course, a thing.
Let earning a thing mean working as hard to have it as you would have had to work to make it. (Trivially, if you have made a thing, you have of course worked this hard by an axiom of identity, and so you have earned it.)
If you have worked as hard to have a food as you would have had to work to make it (from scratch, of course) then you have expended the calories in that food.
If everyone justly earned everything they ate, everyone would starve very quickly.
The human race is not extinct.
Therefore, property is theft.

>>61059662
>Therefore, property is theft.
I realize now that this conclusion may seem obtuse.
The point I'm making here is that the extreme example of fairness I propose as a definition of property (owning = earning, earning = expending energy equal to that necessary to create from scratch) is unrealistic, and is not the actual definition we use.
However, it's the only definition that's truly fair.
Since the definition we use must by necessity fall short of this definition, and by extent of true fairness, our definitions of property are therefore UNfair.
An unfair definition of property is akin to theft.
In this, I have proven that "property," as we know it, is theft. (From mother nature, in particular.)
However, I have also proven that theft (from mother nature) is necessary for survival and there is fundamentally no alternative.

This is a very limited perspective on what "flat" means. I'm talking about "flat" in a multidimensional sense. You're correct that there are no dimensions in which the Earth is 2D. That query doesn't even make sense. But if I could perceive more dimensions than the Earth occupied, the Earth would be "flat" to me. The fact that I can't should not prevent any sensible person from being able to extrapolate the word in those terms.

>but i can express any possible coordinate inside that tesseract with 3 coordinates (x, y, z) from any fixed point in its vicinity.
No you can't. You could if we were reasoning about its projection into 3D space. But you wouldn't be describing the full tesseract, you'd be describing the infinitely "thin" (or "FLAT") slice of it expressed in the world we can perceive.
What's more, what we're actually reasoning about here is even less than that. It's an animated gif of what we would see if we observed that 3D "slice" from one angle.

>>61060207
Wrong.
"Flat" to a flatlander has to additionally have exactly 0 height. Because it's a flatlander who's using the word.

Thanks for proving you only have the brain power to read a maximum of one sentence per paragraph.
>The term is often generalized for higher-dimensional manifolds to describe the degree to which they approximate the Euclidean space of the same dimensionality.

>>61060269
The way that made me click is saying that dynamic programming is building part of the complete solution every time you iterate.

Djikstra's algorithm for instance is dynamic because you build part of the best path every time you iterate.

>>61060298
Are you implying that using the generalization of the term isn't formal?

>>61060293
Apparently Das Kapital did.

>>61060255
Uhm the "flatlander" is a point in the 2D space, right? You can refer yourself in general theory

>>61060310
No, I'm implying the generalization of the term is fair game, and therefore the Earth is "flat" when viewed as a degenerate case of an N-dimensional manifold where N > the number of dimensions that there actually are.

>>61060315

I feel the same way about dynamic programming as I did when learning about mathematical induction.

Induction is a concept that is easy to grasp if explained to you in a clear way. I'm finding it pretty hard to get hold of a resource that explains dynamic programming to me like I'm a moron. I've been following along with MIT lectures and I get the gist of about 40% of it.

I'm making a video game that uses python as the scripting engine.

Right now, I have a shitload of boolean variables for states like "GunMode" "Walking" and "Jumping" just to name a few. Just for game logic scripts like "if Jumping == True, do such and such." It's just very easy for me to write game logic this way.

Eventually, down the line, I would like to cull many of these and streamline it so that instead of having three booleans for 'Standing" "Walking" and "Running" I could just have a single integer variable called "CharacterStandingState" and 0 could be for standing, 1 for walking, 2 for running.

I don't know if it's even worth going through all of that effort though, do you think a script runs any faster with one variable instead of three?

I prefer generics to templates, but obviously you shouldn't be using weakly typed bullshit.

Weak typing with templates has mostly the same problems as normal weak typing, except because they're templates and not generics they still fail to compile.
You end up with cryptic error messages, bad type inference and awkward situations.

yes, but not as a visual metaphor since it will necessarily be a low-dimensional projection. that's not even a 3d projection of a tesseract, it's a 2d projection

i find it easier to think in terms of triangles than squares. at each step of the process you add a point that's unit distance from all previous points. in order to achieve this, you always have to add another dimension
>a point is 0d. to add a second point that's 1u away, you need to add a 1st dimension
>a line is 1d. to add a third point that's 1u from both ends, you need to add a 2nd dimension
>a triangle is 2d. to add a fourth point that's 1u from all 3 corners, you need to add a 3rd dimension.
>a tetrahedron is 3d. to add a fifth point that's 1u from all 4 vertices, you need to add a 4th dimension
i think of the final point as being "inside" the tetrahedron (i.e. equidistant from the other points), but it's also *in the future*. the 4th dimension is time. the edges to the final point take "longer" to traverse because they go forwards in time, so they're 1u long even though they don't look that way in 3d
