>>60567042
I was talking to someone a few threads ago about opcode bits in instruction encoding, and they mentioned RISC-V using 7 bits, instead of my 6. However, the two most significant bits actually tell if the instruction is compressed, and then act as the opcode if it is.
This seems retarded.
Not only do you _LOSE_ opcode space (32(5 bits)+4(compressed) opcodes), it also seems awfully myopic for future expansion, as this is the lowest I've seen a RISC architecture go with opcodes, and MIPS has 6 bits, and AFAIK is slowly running out of space to expand.
This also invalidates this criticism given of MIPS in the RISC-V design document(lack of opcode space), as they've done it to themselves.
Can someone correct me on this?

Wait, so what would equivalent code like this look like in D?

fn return_tuple() -> (i32, char, f64, &'static str) {
    (123, 'b', 3.21, "Hello World!")
}

fn main() {
    let (_, b, pi, hello_world) = return_tuple();
    println!("{}, {}", pi, hello_world);
}

I have a function returning a single tuple which contains an integer, a char, a double and a string literal and i call the function, destructuring the tuple, ignoring the integer.

People are probably going to take one look at your code and see

and say no. The following is intended for those people.

THERE IS NOTHING FUNDAMENTALLY WRONG WITH THE USING DIRECTIVE.

>namespace pollution
This is only a problem if it's done in a header file.

This is basically not a problem if you don't call your classes excessively general names such as "string." It's especially not a problem if you capitalize your user-defined types, as this person is doing.

gets to be just Node in C++, unless you're referencing it before you declare it. That's a feature of the language.

define inOrder maybe?

mixing scanf and cout... well technically scanf clashes with cin and cout clashes with printf, so it's fine but it's weird. lrn2 cin>>, although iostreams are arguably bullshit, so use printf and be proud of it.

newNode could be made into a constructor and

new Node(n1)

used instead.

deallocate those nodes, even if it doesn't matter in that case.

They don't have a name you mean. Why do types not exist unless they are explicitely named? expressions have types, (or values if you're a faggot), and

tuple<int, string, float>

wrong, they're ordered differently in memory

You never said it was false though. You only said the other thing I said was false, which I concede, because we were talking about records, not structs. I'm not repeating the second thing I said to give it more credence, I'm repeating it to remind you I said it, because you seem to have ignored it.

Anyway, how exactly is this reasoning flawed?
let x and y be constants

let T be a tuple such that typeof(T[x]) == int and typeof(T[y]) == float

let U be a tuple such that typeof(U[y]) == float and typeof(U[x]) == int

T and U are of the same type

How does that have anything to do with the fact that T and U are the same type?

>>60568302
I am telling you, all you are doing is making this inconvenient and awkward for everyone.
Everyone knows they are different.
Here, a simple proof:

T = (Int, Float)
U = (Float, Int)

fst T = Int
fst U = Float

fst T =/= fst U
T =/= U

>>60568272
How the fuck does assignment work then?

>>60568331
>T = (Int, Float)
>U = (Float, Int)
Wrong. This assertion is inconsistent with the definitions I provided of T and U.

Read CAREFULLY:
Let x and y be integer constants.
T and U are tuples.
T's element of index x is an int.
T's element of index y is a float.
U's element of index y is a float.
U's element of index x is an int.
How are T and U not the same types?

>>60568369
I don't give a damn what your definitions were, I just proved that they weren't the same.

Your logic would say that sin(x) = -sin(x) because if you let y = -x then sin(x) = sin(y)

>>60568358
Same as records, but with the subscript operator.
T[x] = 1
T[y] = 3.0f
U[y] = 3.0f
U[x] = 1
T == U

>>60568389
Your argument was that records and tuples aren't the same because order matters in tuples but not in records.

My argument is that the two kinds of order you're comparing are incomparable. Ordering of fields in a tuple is not analogous to ordering of field declarations in a record. A closer analog to ordering of field declarations in a record would be ordering of declarations of variables used to store indices into tuples, and THAT order indeed does not matter, just as in records.

>>60568398
But if U[y] = 1 and U[x] = 3.0 it would still work?

>>60568452
No, but that doesn't matter. That also wouldn't work with a record.

>>60568449
>Your argument was that records and tuples aren't the same because order matters in tuples but not in records.
that's simply one point

>>60568449
>My argument is that the two kinds of order you're comparing are incomparable. Ordering of fields in a tuple is not analogous to ordering of field declarations in a record. A closer analog to ordering of field declarations in a record would be ordering of declarations of variables used to store indices into tuples, and THAT order indeed does not matter, just as in records.
No, the key here is that, if we assume tuples are a case of records,
(Int, Float)
is sugar for
(1 : Int, 2 : Float)
which IS equal to
(2 : Float, 1 : Int)
which ISN'T equal to
(Float, Int)

>>60568472
But they're the same type?

>>60568389
>Your logic would say that sin(x) = -sin(x) because if you let y = -x then sin(x) = sin(y)
Isn't he only talking about type equality? Your claim their seems a little outside his field of discussion, but I'm just butting in so maybe I'm mistaken here.

Yes, I agree. But that doesn't mean records and tuples aren't the same thing. Records just have names assigned to their indices. Record { x: Int, y: Float } is comparable to (1: Int, 2: Float), not simply (Int, Float); and therefore, Record { y: Float, x: Int } is comparable to (2: Float, 1: Int), not to (Float, Int). And, as you pointed out, (2: Float, 1: Int) is the same as (1: Int, 2: Float), just as Record { x: Int, y: Float } is the same as Record { y: Float, x: Int }. So, tuples and records really are the same thing.

>>60568488
No. They aren't.

>>60568553
>But that doesn't mean records and tuples aren't the same thing.
Yes it does.
When someone says "Record" that does not mean "Tuple".

In fact, a Record can also be thought of as a tuple PLUS a list of field names

Which is just a tuple. Because names are not data.

>>60568616
>Which is just a tuple. Because names are not data.
Nonsense.

>>60568606
The order of assertions doesn't matter.
It doesn't matter whether you first say that T[x] is an int and then that T[y] is a float, or first that T[y] is a float and then that T[x] is an int. Which is exactly the same kind of order that doesn't matter with records.

>>60568645
You're manipulating the scenario to create a false impression.
The "order matters with tuples" precisely when you aren't considering the record interpretation, i.e.

(Int, Float) =/= (Float, Int)
This is clearly a case where order matters, and they are tuples.
This single example alone proves the case IRREVOCABLY.
Anything beyond this is meaningless bullshit.

You are instead manipulating this to interpret the tuple as a record
(1 : Int, 2 : Float)
and THEN saying order doesn't matter
Well guess what, the tuple order is what gives those fields those names in the first place

>>60567630
Could someone elaborate on this record type please? The way some people are writing things, it almost looks like you're talking about a hash table(also commonly referred to as a dictionary), but that can't be it... right?

>>60568635
>Nonsense.
Not so.
Let x and y be constants.
If you evaluate x, you get the constant value for which it stands, with no name attached.
If you evaluate "x", you get a name, but it has no relationship to the constant.
The connection facilitated between the name and the constant is illusory and abstract. It is not data.

>Let x and y be constants.
No.
Enough with your bullshit.

>>60568678
>(Int, Float) =/= (Float, Int)
>This is clearly a case where order matters, and they are tuples.
Record {one: Int, two: Float} =/= Record {one: Float, two: Int}

>>60568687
Imagine a struct, but without the implied memory layout, and the order of fields doesn't matter.

>>60568709
Let x and y be field names in record R.
If you evaluate R.x, you get the constant value for which it stands, with no name attached.
If you evaluate "R.x", you get a name, but it has no relationship to the constant.
The connection facilitated between the name and the constant is illusory and abstract. It is not data.

>>60568718

Hey you. I heard you answer questions. I've got one. Or anybody else who knows.

Is there a speed difference between Boolean arithmetic and if operators?

In other words, is there a speed difference here? Assume we're talking about the lowest level language both of these expressions are possible in. Say, C(I'm not sure if Boolean arithmetic works like this in Assembly).

if(c > 0):
x += 5

vs

x += (c>0)*5

I'm actually most curious if one or the other is faster in HLSL or not. I've heard if statements are to be avoided in HLSL but not exactly why.

Also, if your """language""" actually runs on a computer, your records are tuples. Their field indices are numeric. This is a necessary truth, because all data stored on a computer is numeric.

A tuple is like a record but its field names are integers.
A record's field names are integers.
Therefore, tuples are records.
(For what it's worth, records themselves are also integers.)

There are CL's that run on the JVM so your point is invalid. All things aside the JVM is nothing to be allergic to and quite the opposite. It is a seriously impressive piece of software.

>>60569371
The JVM can't even support TCO so it's automatically garbage.

>>60569264
Point is, theory doesn't matter. It's theoretical COMPUTER science we're talking about, not just theoretical science. Records and tuples are the same thing: they're both serial data structures with numeric indices. A record's indices need not LOOK numeric, but nor do a tuple's indices.

let pa = &aliens;    //pa should be a pointer
println!("Third item via pointer: {}", pa[2]);    //string

>>60569400
And maps and lists and vectors and trees are all the same too! Everything is just an integer!

>>60568770
I would try learning from scratch. The person who told you to learn as you go seriously fucked you.

There's nothing to be done with that crap you wrote. Read the official tutorial, from top to bottom, do all the exercises and try again.

Oh so you mean C?

>>60569435
C and C++ are the same too and Java and Javascript

>>60569419
That's actually true though.
An entire hard drive is an integer.

i have a recursive algorithm with some matrix operation with int arrays which are stored as a 1d arrays.
my algorithm has many tricky breakpoints and my arrays are always allocated dynamically, which gives me memory leaks.

question to the c++ friends:

int * mat_mul(int * mat,int * B,int m,int n, int p) {
    int sum;
    int * res = new int[m*p];
    for (int c=0;c<m;c++) {
        for (int d=0;d < p;d++) {
            sum = 0;
            for (int k=0;k < n;k++) {
                sum = sum + mat[c*n + k]*B[k*p + d];
            }
            res[c*m + d] = sum;
        }
    }
    return res;
}

i dont want to switch my int * to vectors, id like to try to allocate my arrays with smart pointers. i tried it with this matrix multiplication algorithm but just exchanging

int * --> unique_ptr<int[]>

doesnt work. can somebody lead me into the right direction?

>>60569384
Regardless, you have failed to come up with a single way that CL is substantially different from clojure.

>>60569467
>bits

>>60569500
Clojure is a Lisp-1, automatically throwing any hope of a decent macro system into the trash.

>>60569510
Basically, though, tuples and records are the same thing because names aren't data, and names aren't data because all languages in which names are data are shit. If it takes you longer than constant time to perform name resolution, the language you're using is garbage; and if it doesn't, I guarantee names are not data in that language.

>>60569880
name being data and O(1) resolution are not exclusive (eg: java)

I sure do love dynamic typing! Dynamic typing is the best!

Pretty sure what he's talking about is, in Java names are resolved at compile-time - but if you NEED them at run-time, you can do reflection.

>>60569880
>O(1)
says who

>>60570335
yes. if types are data, something like this would be possible

Type R is Record { age, sex };

R r;

r.atIndex( type(r).fields.getIndex("age") ) = 18; // dynamic

r.age = 18; // static

getting the index of a field is not O(1) but once you have the index, you access the field with an O(1) complexity.

>>60568988
Yes, it can be, which is why I included a note about what languages I was interested in relative to the question, but above machine language I don't know if there are any languages that can't do both, so it seems like a relevant question for almost any language.

>>60569216
I see, thanks, it's interesting to see in Assembly. I figured that would be the case but I've never been entirely sure until recently how "if" operators worked(although lately after studying Assembly somewhat I think I get what's going on now), especially as opposed to Boolean arithmetic, in any language.

I guess an equivalent question based on my small knowledge of Assembly is that, I know that comparison( and even general) operations in Assembly tend to have side-effects of setting flags which are used in conditional branches and jumps. Is it true that using the values of the flags in the flag registers themselves to do the conditional operations would be faster than actually setting up a conditional jump, then? If that's exactly what you're doing there and I don't recognize it, sorry.

>>60570826 again.
To elaborate on my extended question after the second quote, I can't really write code in assembly yet but...

Say you have an operation of int a - int b. The result of this sets a flag in some register which contains the information of whether the result was greater than 0(as a 0 or 1 value). Is it true that if you wanted to set some variable C to 5 if the result of a - b was > 0, then instead of using a conditional jump statement like jg, it would result in faster execution(minimally?) to add 5 multiplied by the value in the flag register to C?

Yes

Why would I care about an assumption made by someone who is retarded?

The average of which race?

How can someone with above 100 IQ be retarded? Now I definitely know you're lying.

>>60571736
can we not bring politics into these threads? i'm of the race people who align with you ideologically sometimes erroneously refer to as "niggers" and i'd prefer to think of the lot of you as cool people who i can discuss programming with, without having to know you would hate me if you knew what i looked like

I don't know if this really counts as programming, but I don't want to make a new thread for this. For the Arch Linux users here, what do you use to install packages from aur? I've tried yaourt, but I'm wondering of people here prefer alternatives.

>How can someone with above 100 IQ be retarded?
Because they are. Maybe you country has a lower average IQ and you are thinking you aren't retarded but that's only in comparison to your "people".

>>60572200
"retarded" isn't an intelligence spectrum, it's a specific developmental disease of which reduced intelligence is only one of the many effects

>>60572200
Why would the average in my country matter if I said "above 100", not "above average"? You seem to be pretty retarded yourself.

NEW THREAD!!

It doesn't. If you are below 100 you are retarded, plain. Simple.

Pardon, but Excuse me, but I'd simply like to hold you up for one short while. What you're proclaiming to be Linux, is in actuality, GNU/Linux, or as I have of late taken to calling it, GNU + Linux. Linux isn't an operating system on its own, but rather another free piece of a fully working GNU system made useful by the GNU core libraries, terminal facilities and essential system components comprising a full OS.

Quite a few computer owners use a subspecies of the original system daily, but do not know. Through a particular chance, the version of GNU which is widely utilized now is often called "Linux", and many of its owners do not know that it is practically the GNU system, created by GNU.

A true Linux does exist, and this population do have it installed, but it is simply a part of the system they use. Linux is a core: the part of the system that allocates the machine's resources to the other programs that you run. The core is a necessary part of an operating system, but relies on the rest of the system; it will work only in the shadow of a complete operating system. Linux is normally utilized in combination with the GNU operating system: the whole system is practically GNU with Linux added on, or GNU/Linux. All of the alleged "Linux" releases are really releases of GNU/Linux.

Why did you mention it then? I said I'm not below 100.

>>60572212
I know how to do it, and I've seen the wiki page on aur helpers. I was just curious what /g/ uses.

>>60572244
Blame the people that made arch linux for not calling it Arch GNU/Linux

>>60572248
>I said I'm not below 100.
And you are wrong.

>>60572184
>i'm of the race people who align with you ideologically
I'm not sure I understand what you're trying to say here. There isn't really any race currently which aligns with me ideologically.
>without having to know you would hate me if you knew what i looked like
If you could prove certain things about yourself then we could arrange an honorary title for you.

download packer.pkg.tar.xvf.gz
tar -xvf packer
cd packer/
makepkg -sri

Now you can use packer

So I'm dead set on learning C this summer so is there anyway I have break open area and see the code it runs on?

>>60572272
My sentence structure must have confused you. It's a bad habit of mine. What I was trying to say is that I'm black, and people who align with you ideologically seem more often than not to think badly of me for that, and because of it, when discussion turns to politics around here, I find myself harshly reminded that we're not all friends here.

I suppose I'm being unreasonable here, though, and there's already a new thread open, so never mind.

>Can someone correct me on this?
No, because it's true. Pic is related.

However, ISA extensions usually regard fairly esoteric instructions that don't necessarily need to be optimally encoded, and RISC-V has ample space in >32-bit instruction formats for those.

>>60572376
>What I was trying to say is that I'm black
That would mean there is a very high chance of you holding absolutely retarded beliefs.
>people who align with you ideologically seem more often than not to think badly of me for that
Not necessarily of you in particular, just of your "people". If you agree that most of your "people" hold pretty retarded beliefs and you don't hold them yourself, then I don't think any reasonable person would have a problem with you.

>I find myself harshly reminded that we're not all friends here.
Most people here aren't friends regardless of race.

i already had two reasons not to stay here:
>it was unreasonable of me to ask people to change their behavior just to make this environment less intimidating
>there's already a new thread open
now i can add a third to the list:
>it's immediately obvious from your reaction that you cannot be reasoned with and i am wasting my time
bye

>>60572498
>it was unreasonable of me to ask people to change their behavior just to make this environment less intimidating
That's correct. Nobody should change their behavior to suit you.
>there's already a new thread open
Why would you assume I (or people who agree with me on certain things) won't be participating in that thread?
>it's immediately obvious from your reaction that you cannot be reasoned with and i am wasting my time
That's wrong though. I'm assuming from your reaction that you're just an average example of your people, in which case I doubt that it's possible for you to argue or reason with anyone with a different opinion.
