The new thread should link to the old and the old thread should link to the new. Seems like a double linked list to me.
In the past we had it so only the last thread needed to link to the new one but the double-linked system is better. However we never had it so only the new thread linked to the old one.

>>56162037
It's difficult to distinguish between dynamically and statically typed languages nowadays. What some people might consider as dynamic typing might actually be a union that changes from a preselected range of types in the runtime. C and many statically typed languages have unions and could easily do that, it's just with more syntactic sugar.

>>56162118

>>56162016
because Scheme is good for making DSLs

Sounds more like a technicality.

I would not consider it a strongly typed language, even though it may technically be one, much the same as I do not consider a cucumber a fruit when I'm cooking.

Guess i'll post it here too

currently working on a project, and for the first time im trying to make an accompanying design document to help me stay organized and not have tiny snippets of notes everywhere.
So far this is what i have in the design doc:
>Definitions relating to project domain
>Project goals
>Software description
>list of ux elements
>criteria for completion
>milestones

So far this is all great and has helped me stay more focused and organized, but it doesn't really go into the code(classes,hierarchies,functions), so i find myself going back to my same old disorganized way.

How would i go about documenting the code?

>>56162188
Write out EXACTLY what you need data-wise. Translate that to small lines/snippets of pseudocode.

>>56162188
Personally, I find the Agile design to be great when I'm trying to determine actual tasks that need to be done.

The basic structure is:
Feature
User Story
Task

A feature is a particular function your software should perform, while user stories make up the various possible and desired interactions with the software (both from admin and user perspective), and each "story" can be broken out into specific tasks (the actual code you'll write).

I can only find optimised code for them but no specifications. DES came with it's 'supplementary material', and AES has similar, but Serpent has no such content that I have found thus far.

I need some help I am fetching information from json and printing it to console as well as to a file.

but in printing it to console I have this error:

Traceback (most recent call last):

    text_file.write(json[j]['threads'][i]['com'])
UnicodeEncodeError: 'cp932' codec can't encode character '\xe9' in position 687: illegal multibyte sequence

I am only just really starting out with python and this is something of a beginner project.
I am accessing json data and every time a post has Japanese in it, it throws an error, I am not sure how to deal with this.
I know my CMD is code page 932 but It has never problems deal with Japanese before and still doesn't outside of this error apparently.
I assume that one requesting the json data it gets encoded into the wrong type? or that write() assumes it is a certain type?

I don't want to learn proper Bash scripting and I want to write a few convenience tools.

>>56161867
Reposting in the interest of readability.

Tilde is an assertion that types are equal. (a ~ b) is read "type
a unifies with type b," so a and b may be substituted for one another.

Begin with unknown universal types for each subexpression.

f x = f (f x)
f x = (f :: a) ((f :: b) (x :: c) :: d) :: e

Like terms f unify, a ~ b:

f x = (f :: a) ((f :: a) (x :: c) :: d) :: e 

Observe the inner subexpression:

((f :: a) (x :: c) :: d)

We see f applied to x, so it must be a function of x's type with the given
result type, i.e. a ~ (c -> d)

f x = (f :: c->d) ((f :: c->d) (x :: c) :: d) :: e

Now ignore the inner expression, but for its overall type:

f x = (f :: c->d) (_ :: d) :: e

We see f applied to an argument of type d, so c ~ d:

f x = (f :: d->d) (_ :: d) :: e

We have already proved that (f :: d -> d), but for the sake of
completeness we see that the overall result type also unifies with f's
domain, i.e. d ~ e, given the final typechecked expression:

f x = (f::d->d) ((f::d->d) (x::d) :: d) :: d

>>56163867
And since the thread is deleted and rbt seems down, the post in question said something like this:

>>56163995
use pure functions with monads

>>56163968
That doesn't have the same type either.

 apply :: Applicative f => f (a -> b) -> f a -> f b

>>56163978
t -> t is clearly not monomorphic. What are you even saying? I already gave the typechecking proof that f :: t -> t, and it has nothing to do with the monomorphism restriction, if that's what you're trying to say.

Reverse the order and you have them ranked by best to worst.
Exceptions suck, but a sufficiently smart / paranoid compiler knows if you forgot to handle them all and can force you to (or at least raise a warning).

I'm not always 100% against side effects, but I don't want them happening during errors.

Probably because you tried to shove an int into a struct you don't know the fields of. In the case of the above example type, you tried to put an integer into a string field.

Learn the difference between "class" and "object".

>>56164812
I know the difference, but what I'm saying is why the fuck do they exist at all? Why can't I just get the variables when I ask for them instead of jumping through a dozen hoops?

>>56164842
Get what variables?

>>56164799
Percisely because they're "instances" with common "interface".

Take this C code:

struct Person {
    int age;
    int height;
};

struct Person *person_create()
{
    return malloc(sizeof(struct Person *));
}

void person_delete(struct Person *person)
{
    free(person);
    person = NULL;
}

int person_get_age(struct Person *person)
{
    return person->age;
}

void person_set_age(struct Person *person, int age)
{
    person->age = age;
}

struct Person *joe = person_create();
person_set_age(joe, 15);

struct Person *alice = person_create();
person_set_age(alice, 10);

fprintf(stdout, "Joe is %d, Alice is %d.\n", person_get_age(joe), person_get_age(alice));

person_delete(joe);
person_delete(alice)l

Now, in OOP terms it's something like this:

struct Person
{
    int age;
    int height;

    const int getAge() const { return age; }
    const int getHeight() const { return height; }

    void setAge(const int age) { this->age = age; }
    void setHeight(const int height) { this->height = height; }

    Person(): age{0}, height{0} { }
};

Person *joe = new Person;
joe->setAge(15);

Person *alice = new Person;
alice->setAge(10);

fprintf(stdout, "Joe is %d, Alice is %d.\n", joe->getAge(), alice->getAge());

delete joe;
delete alice;

Thus why they "do not share the variables", if you want to share a variable, you need to make it static.

>>56164842
Either make them public or expose them through getters. Not exactly a dozen hoops.

>>56162126
and the type of the union is what? -- a union!

your post has a lot of disinfo in it. it's extremely easy to distinguish statically typed versus dynamically typed languages.

most commonly, dynamically typed languages can have variables declared with no type. this is because they are dynamic.

>>56164875
Untyped =/= dynamic

Dynamic types can be recovered with static types if you have dependent pairs and RTTI.

>>56164875
>dynamically typed languages can have variables declared with no type
dynamic typing != implicit typing

>and the type of the union is what? -- a union!
And this is wrong, it shows that the type of the variable is one of the listed types.

>Probably because you tried to shove an int into a struct you don't know the fields of. In the case of the above example type, you tried to put an integer into a string field.

I don't think that's the case. It still calls time_t constructor with int paremeter when invoked through an initializer list. To further debunk that statement, it returns the correct output when invoked through initializer list - that wouldn't be the case had the string been initalized instead. I'm looking around and it seems that the standard explicitly states that a warning (diagnostic message) should be issued when a value is downcasted in an intiailizer list, but no mention of it when using a regular constructor syntax. Unless I'm misunderstanding what they just quoted from the standard.

no one cares about the underlying nature of the language. the point of dynamic types is that you don't need to worry about manually declaring whatever type it might be. when the language can do it itself at compile time

>>56164916

$ echo -e 'package main\nfunc main(){\n\tprintln("hello world!")\n}' > hello.go
$ go build -ldflags '-s' hello.go
$ du -h hello
616K    hello
$ ldd ./hello
        not a dynamic executable
$ ./hello 
hello world!

yeah, this was my whole point. any language where you're typing out the type, e.g. Integer, is one that is statically typed.

You don't know what you are talking about.

Best way in Java to match together 3-4 types of data that rely uppon each other, without changing the classes themselves?

e.g. 3 zoos, 5 animals in first zoo, 4 in 2nd, 1 in 3rd, and then each animal has some nickname, maybe add something else.

I realise something like this should be handled by classes, whole point of OOP, but outside of messing with classes, how to handle this?

Only idea I have so far is one HashMap to match Zoos with list of Animals, and then another HashMap which contains all Animals matched with their nicknames, new information would complicate this even further.

You are doing something wrong then.

>>56165122
Dynamic type means ANY type.

>>56165119
If you have to write the type, it's manifest typing. You can have static typing that is not manifest, but it never makes sense to have manifest dynamic typing and certainly not with no types at all.

       (195, 89, 89)
]

b = zip(*a[::-1])

outputs:

So I'm scraping a website that is aids infested autism, and I would like some help with writing a regex for this shit.

On good days, the text I'm looking for will look like this:

"Payout: 15.210 USD"

But sometimes, it can look like this:

"Payout: 15</span><span class="W">.210 USD"

And sometimes even:

"Payout: 15.210</span><span class="W">USD"

I'm not sure if the tags are the same each time it happens, but probably not.

How do I safely extract the payout without all the shit tags cucking my shit?

>>56165494

How do you motivate yourself once you solved the core problem?

I spent the last weeks reverse engineering and my motivation dropped to 0 after the proof of concept. But I have to write an article now, polish the code etc... ZERO MOTIVATION
I hate this
This is why most of my projects are never finished
Polish is boring and tedious

I keep hearing about it, but I see nothing on it. What exactly is raycasting? I'm not talking about Wolfenstein 3D or DOOM, i'm talking about scanning nearest points to an entity.

Like in a 2D plane, there's the x axis and the y axis. What I assume is that at the beginning of the logic loop I go through the entities and scan their nearest points.

I would also assume you handle them individually per axis.

So in a 2D tile based game, when moving on the x-axis, you scan in the direction you are heading, but narrowing down your scan range to columns your entity intersects with.

Is this correct?

Also what is fixed-point and how do I do that?

how does memory adressing working assembly work in two sentences ?

if my cpu only talks in 32/64 bit instructions how can I tell the cpu to move value in 0x000001 to 0xffff32 I'd need at least 64 bits for a 32 bit cpu, wouldnt I ?

>>56167293

>>56167303
thats not how you encourage people, he obviously does not know what he's doing wrong or its bait in which case: fuck me, I fell for it again

>>56167333

push eax
mov eax, [0x000001]
mov [0xffff32], eax
pop eax

>>56167398
if its not too much, how does this "get processed" by the CPU, obviously it cant take more than 64 bit "words" can it, where am I wrong here ?

Why would anyone use Javascript when Typescript exists?

>>56167465
Why would anyone use *script when Emscripten exists?

>>56167424
It don't really understand what you mean, but neither

0x000001

, nor

0xffff32

are 64bit, or 32bit for that matter, though since you use them as memory addresses they are interpreted to 32bit or 64bit addresses depending on your cpu.

The snippet I posted does this:
Pushes eax on the stack, to store any data there, this is not necessary if you know what's in eax, and whatever it is can be thrown away.
Moves whatever the memory location

0x000001

contains into eax.
Moves what has been put into eax into memory location

0xffff32

.
These two moves are necessary, since you cant move data directly from one memory location to another.
Pops the old eax value of the stack and back into eax, i.e. restoring eax.

>>56167533
thanks for the write up, I just randomly chose those values, also im sorry I could probably read it up somewhere but eax works in this case as our cache right ?

also, when I run multiple programs and they each use the 0x000001 adress where they store something, wouldnt it totally fuck up the whole process (or computer for that matter), or is it the OS's job to manage the memory ?

You need decoupling and cohesion. Objects are a tool that can accomplish this, not a silver bullet.

I have a math / code question.

In my application, I have a graphic effect of a line that is initially straight as an image. The user can use a finger gesture. I want to basically have the image come on screen and be rotated so that the line follows the finger gesture (front finger start point to finger end point). After that, the image is made invisible and its rotation is reset until the user does it again.

What's the math formula for pulling this off?

>>56168877

>>56168915
Why is that necessary? I'm mostly manipulating the quaternion rotation of a 2d image

>>56168946
lmao I don't know what are you talking about

>>56168957
The fuck else you want me to call it? Just rotation? Does that make your autism feel better?

>>56168800
arctan

>>56168966
I'm remarking that quaternions are for 3D rotation (and uniform scaling). 2D rotation is an angle, 2D rotation and uniform scaling is a complex number.

>>56168989
I'm well aware, but throughout my career, we use quaternion rotations as a term most of the time cause we're usually using 2d images inside a 3d environment.

Can this be refactored? It's supposed to be like a Fibonacci generator that takes 3 numbers instead of 2.

def tribonacci(sig, n):
    if n < 3:
        return sig[0:n]
    else:
        a = 0
        while a < (n - 3):        
            sig.append(sig[a] + sig[a+1] + sig[a+2])
            a += 1
        return sig

a signature of [1,1,1] to 10 would be [1,1,1,3,5,9,17,31,57,105]

Hey guys, trying to think of a way to better use pipes

currently i have two programs, you can assume these programs both repeat so its essentially: write, read, write, read continuously

one: opens pipe for writing -> writes some commands -> closes
second: opens pipes for writing -> reads while fgets isn't null -> closes

the problem is that the reader gets all of the commands in the pipe from the start of runtime instead of just the NEW commands. So how do i make a new file every time and overwrite the old one?
