ah entonces el mismo vector dirección no implica el mismo espacio

median trail
#

if you are using vectors then it's easier

gusty ermine
#

mentira, si implica eso XD

porque te dan el vector com AB

y si AB=CD entonces las componentes son iguales

I broke my internet modem

#

😅

#

I’m just connecting directly the cable with the plug on the modem

#

Por si le pasa a otro!

fallow dock
#

cómo lo rompiste

#

xd

sweet cape
#

Tiene un pedazo de plástico que lo cubre, como un tubo entonces le pegue martillazos, definitivamente la entrada hembra del cable se zafó de la placa, entonces cogí el cable y lo deje haciendo contacto con la parte que la entrada hembra hacía

#

Haha

#

La parte negra de arriba a la derecha, que es el conector del cable se dañó por que el cable estaba muy pegado, cuando lo gire hizo que toda la parte girara entonces se partió

fallow dock
#

tal vez puedas pegarle para que se des-parta y se arregle

#

un buen zapateo y suerte cuántica, todo es posible

#

sabiondos te dirán algo de "resoldar"

#

pff

#

Ya lo quite

#

Es decir, salió esa parte y el cable

No tengo ni soldador, lo puse a que el viento y densidad hagan su trabajo de tenerlos en el mismo lugar haha, básicamente están haciendo contacto por inercia

Raise your hand if you're also using italki.

#

I've started referring people to this Discord - such a great opportunity because of the huge community. wolfcheer

hollow wedge
#

have you been using italki?

still radish
#

I used it a few times

fallow dock
#

uh what is this supposed to mean
it says you used the GitHub API to "login" with Requests, which is a Python library to do HTTP requests (that's probably the default user agent python-requests/whatever)

#

you probably used some other program that used Requests as a dependency I suppose?

#

python-requests/someversion is just the default user agent for Requests

#

cool that I don't use passwords for GitHub what a pain though

I was telling a friend differences between languages and I got carried away

#
import java.util.Collections;
import java.util.List;

class Wea implements Comparable<Wea> {
    int valor; // (no getters and setters)
    
    Wea (int valor) {
        this.valor = valor;
    }
    
    public int compareTo(Wea otraWea) {
        return this.valor - otraWea.valor;
    }
    
    public String toString() {
        return Integer.toString(valor);
    }
}

public class RubMaker {
     public static void main(String args[]) { 
         List<Wea> weas = Arrays.asList(new Wea(2), new Wea(-5), new Wea(50), new Wea(9)); // fixed

         System.out.println(weas); // -> [2, -5, 50, 9]
         Collections.sort(weas);
         System.out.println(weas); // -> [-5, 2, 9, 50]
     }
}```so, first I wrote this, in Java 8
#
data class Wea(val valor: Int): Comparable<Wea> {
    override operator fun compareTo(other: Wea) = this.valor - other.valor
}

fun main() {
    val arr = arrayListOf(Wea(2), Wea(-5), Wea(50), Wea(9))
    println(arr)
    arr.sort()
    println(arr)
}```then Kotlin
#
>>> from dataclasses import dataclass
>>> @dataclass(order=True)
... class Wea:
...     valor: int
... 
>>> lista = [Wea(n) for n in (2, -5, 50, 9)]
>>> print(lista)
[Wea(valor=2), Wea(valor=-5), Wea(valor=50), Wea(valor=9)]
>>> lista.sort()
>>> print(lista)
[Wea(valor=-5), Wea(valor=2), Wea(valor=9), Wea(valor=50)]```then Python (ye, in the REPL, whatever)

@fallow dock dude i have no idea what you mean by that

#

like what did i do wrong

#

did i do anything at all

fallow dock
#

I dunno, did you use any program that identified yourself to GitHub?

#
>>> import json
>>> import requests
>>> 
>>> req = requests.get('https://api.github.com/user', auth=('my user', 'my password'))
>>> 
>>> json.loads(req.text)['message']
'Bad credentials'
>>> req.text
'{"message":"Bad credentials","documentation_url":"https://developer.github.com/v3"}'```it's something like this
#

basically talking to GitHub to ask it to do things. And it replies back with JSON

#

ah I fucked up the URL lol

#

it's /user

I dunno, did you use any program that identified yourself to GitHub?

It's actually done a lot more often now so it's cool to see that stuff happening

still radish
#

some examples

#

to be honest I pronounce the vowels in ride and write very slightly differently

#

the beginning of a differentiation between idle and idol is interesting

#

I think I even have a slight differentiation on idle/idol too but it's super subtle

makes it all the more bizarre that spanish has the phonology it does

maybe I'll ask in the spanish one for examples of spanish diversion

hollow wedge
#

that would be cool

#

they soemtimes have nasalisation happening with n's that end syllables

still radish
#

but is it a split?

#

I can think of lots of variation in pronunciation i.e. ll

hollow wedge
#

I don't think the ll thing is a split, since the sound changes for all ll's

#

conocer would not get nasalized, while concuerdo could.

#

so I think it's a split

Tengo una pregunta para la gente que vive en España. Me gustaría mudarme a España y trabajar allí (soy de Eslovenia), como diseñador de front-end web, sé HTML, CSS (con Bootstrap) y algo de JavaScript. También tengo un poco de experiencia con C# y bases de datos y actualmente estoy tomando un curso de desarrollo web donde también aprenderé un poco de back-end con Python. También me encantaría trabajar (o prefiero trabajar) como reparador o técnico de computadoras.
Por favor, sepan que mi comprensión del español es básica y me estoy ayudando a mí mismo con "DeepL Translate", pero soy muy fluido en inglés, también pasé 4 meses viviendo en EE.UU.
Si pueden ayudarme de alguna manera lo apreciaría mucho, por ejemplo donde buscar esos trabajos, cuales son mis opciones, si es posible para mi o no.
Y por favor, mándame un mensaje en privado en inglés o en español, porque este canal recibe muchos mensajes y todo sería confuso.
¡Muchas gracias a todos!

With distance learning (or how it is called in English) we have twice as much homework as in ordinary days.

@abstract scaffold I have a question regarding sqrt, when we do something like

x^2 = 4 then we take sqrt on both sides

x = +/- 2

is the latter incorrect? I was reading stuff about taking square roots, and when we cancel out the exponents it's because I'm assuming the base which is x in this case is positive, right?

abstract scaffold
#

x = +/- 2 is not incorrect if you were given x^2 = 4 at the start

median trail
#

exactly

#

since the notation sqrt is for the positive "solution"

abstract scaffold
#

yeah, sqrt just means positive. thus need to include +/-

#

due to the definition of the inverse of a parabola

fallow dock
#

anyone here on Ubuntu?

median trail
#

yeah, sqrt just means positive. thus need to include +/-
what

#

I'm lost, I thought sqrt was for positive solutions

#

ohhh

#

I get it now

#

but I'm just confused because of the fact of the exponent of the x

abstract scaffold
#

x^2=4?

median trail
#

like

sweet cape
#

La raiz cuadrada de un número puede ser positiva o negativa

median trail
#

I know juan

#

I don't care about that

#

I mean

#

the thing is

#

doing this (x^2)^(1/2) = x, I'm assuming x is positive, right f14?

abstract scaffold
#

ah. yes. if x>=0

gusty ermine
#

Hola

median trail
#

because if I do this (-2)^(1/2) = -2

I could get weird stuff like -2 = 2

abstract scaffold
#

sqrt(x^2) = |x|

sweet cape
#

Ahh si

#

Ahí es lo de valor absoluto

#

Ese tema me costó entenderlo cuando lo aplicaban a los limites 😅, con enteros es relativamente fácil

abstract scaffold
#

@real imp is ex.9 trying to tell you to find a sufficient condition?
if so, currently the statement is only necessary because it could still be a "kite"

real imp
#

i got it

#

it's not... the sides

#

it's the diagonals

#

i forgot everything about geometry

#

but someone explained it to me whoops

sweet cape
#

Whoops

real imp
#

basically it says that the necessary condition for it to be a rhombus it's that the diagonals intersect perpendicularly

#

which is true, and necessary

#

so a sufficient condition would be for example that it also intersects in the middle point of the line

abstract scaffold
#

yes.

median trail
#

wait wait wait I'm a bit confused

((-2)^2)^(1/2) = -2?

((2)^(2))^(1/2) = 2

but if (-2)^(2) = (2)^(2) so -2 = 2? this is what's confusing me f14 haha

sweet cape
#

Ohhh

abstract scaffold
#

or else it could be a kite.

#

((-2)^2)^(1/2) = (4)^(1/2) = sqrt(4) = 2

#

be careful with negatives.

gusty ermine
#

we doing algebra?

abstract scaffold
#

sqrt(x^2) = x si x es mayor o igual que 0

median trail
#

yeah I get this I just don't get why taking the sqrt here and saying +/- is correct

#

x^2 = 4

sweet cape
#

Estas igualando una operación que tiene 2 resultados distintos

#

Esa es la condición

median trail
#

the thing is... the notation sqrt is defined for positive numbers, that's why you can't do this ((-2)^2)^(1/2) as far as I know since this way you could get weird stuff like -2 = 2

abstract scaffold
#

because in x^2 = 4

we're technically not taking just the square root.
if we did, we're only looking at the positive solution.

it's like looking at x^3=1... i could take the cube root.... but that doesn't take into account the other 2 complex roots.

#

if we just reverse engineer it, a negative squared always is it's positive counterpart.

#

a more sound proof would just be to "factorise it"

median trail
#

I think I get it now, since the square root of a number a is a number b, such that

b^2 = a

#

so... if I say x = +/-2 I'm just listing the values of b, I'm not canceling out exponents

#

right?

abstract scaffold
#

yeah, you are just listing the values.

sweet cape
#

I’m trying to get it
Because you’re changing values and then f(-2) = f(2) => that’s incorrect in this case

median trail
#

ah now it makes sense

abstract scaffold
#

cancelling the exponents only just takes care of one solution

sweet cape
#

Mhm

#

I can’t change values if the condition is determined, right?

#

Like

abstract scaffold
#

sea f(x) = sqrt(x^2)
f(-2) = sqrt((-2)^2) = -(-2) = 2
f(2) = sqrt(2^2) = 2

median trail
#

now, a parabola is pretty interesting because it shows this duality between the two values of b

abstract scaffold
#

f(-2) = f(2) in this case. even function. need to be careful which branch you're in.

#

yes, even function parabola

median trail
#

f(-2) = f(2) in this case. even function. need to be careful which branch you're in.
yeah in functions it makes sense, since we are not talking about the numbers themselves

#

we are like representing the output of the function

#

I learned something new today :)

#

yay

#

now i get it

@median trail se puede utilizar la raiz cuadrada en ambos lados de la ecuacion tambien, pero en este caso, necesitas tratarla como una ecaucion de valor absoluto.

@abstract scaffold but in this case abs(x) would be a function, right?

#

maybe something about gradient?

i'm not sure if coincident lines are considered parallel.

#

and i'm not sure what a "recta" really is. es una linea con el dominio para toda las x?

median trail
#

a recta is a line y = mx + b

abstract scaffold
#

if it also counts a "restricted domain line", then i could draw a really small line horizontally and on the other half of the page draw a long vertical line such that they don't touch.

real imp

i'm not sure if coincident lines are considered parallel.
@abstract scaffold they have always been considered parallel by my professors, at least so far

#

and yeah, a recta is a line

median trail

yeah my professors do also consider that

real imp

which makes sense specially when you go over 3 dimensions

@real imp compro dulzura natural, que tengo entendido es un emprendimiento chileno. Pero también hay neurobionta en pastillas y en inyección (mcg de B12 para meses). Si no has consumido B12 y consumes de mantención (diaria o mensual) estás manteniendo una deficiencia (según me dijo el nutri) así que puedes excederte un poco porque se elimina con la orina porque que la cianocobalamina es hidrosoluble (dado que estamos en tiempos de cuarentena y salir hacerse un exámen es más recomendable para ser un foco de contagio y eso no lo recomiendo). La B12 es barata, mucho más barata y sana que consumirla en animales inyectados o llenos de colesterol LDL y grasas saturadas (dependencia de estatinas como la atorvastatina en un futuro)// no olvidar eso si te hacen ese punto, que hay un estereotipo en suplementarse súper grande por más que sean consumidores de chocapic/ animales vacunados y suplementados/ leche nido. En las tiendas vegan de tu zona deben vender/dietéticas/farmacia neurobionta o B12 sola en polvillo (y ahí fíjate en las unidades y tu necesidad diaria, que hay B12 en polvo cara pero que es para todo un año).

#

^lo edité varias veces

#

Vale decir que en la actualidad no podemos sacar B12 de los ríos, dado que están llenos de antibióticos, microplásticos y fecas de ganadería como también porque vivimos lejos de ahí (también con mucha sequía). Vale decir también que en argentina ese problema está estudiado, deja mandar un post.

more expensive * (? GWaobloChildPepeShrug

Oops yes

sacred harbor
#

pero igual, supongo que el 8700K está más caro por falta de stock? GWaobloChildPepeShrug

#

ha de venderse más que el 9700K

glass dragon
#

No it's because it has hyper threading

sacred harbor
#

porque, normalmente, al salir las nuevas gen, las anteriores bajan de precio

#

que no es por eso, que si fuera por eso Intel mismo lo anunciaría a mayor precio blobangryglares

#

y sí, puede que por eso sea por lo que se vende más

#

y también el 9700K tiene 2 cores más

glass dragon
#

The price is set by demand and the 8700k is more in demand because it has hyper threading

#

The 9700k has 2 cores more but 4 threads less, and thread count is usually more important than physical core count

sacred harbor
#

depende para qué

glass dragon

Yeah por eso dije usually

First it was they're expensive because they have less stock, then suddenly you said "y esk es lo que te estoy diciendo" un reference to the hyper threading

#

Pero, qué es mi cafetera?

sacred harbor
#

que yo dije lo contrario? que no ves la imagen que puse donde tú lo dijiste o qué? blobglare

#

tu dices que está más caro por el HP, yo te digo que Intel (que es quien pone el precio oficial) dice que el 9700K está más caro

#

Yeah, that's a picture of me saying it's because of hyper threading and you saying it's just because of low stock. Remember, I'm Amaroq and you're dll

sacred harbor
#

que si ahora está más caro el 8700K ha de ser por el stock

glass dragon
#

I'm the purple one in the picture

No, it's because it has hyper threading and thus is more in demand and thus vendors can charge more

UWU NOW I GET IPV4 SUBNETTING

#

OMG IT WAS HARD

#

BUT NOW I GET ITTTTTTTT

#

it's not difficult per se, it's just that binary places were messing me up

#

because it made no sense to me why the first subnet of this ipv4 address 128.168.0.0/16 when subnetting 128.168.0.0/26 (for my exercise purposes) would be 128.168.0.0 and the 9th one 128.168.1.0

#

and then I realized it's because this address in binary is like this

. .00000000.000(networks) 00000(hosts)

#

and if we isolate the network binary number and get rid f the dot notation we get:

00000000 000 which can be interpreted as just one number

#

and since each network is (position - 1) then the first one is 1 - 1 = 0 so

00000000 000

#

then 10th one is like

00000001 001

#

again assuming this is just one binary number that was split because of dot notation

#

00000001 001 = 00000001001

#

and representing this using integers would look like this 128.168.1.32

#

voila

#

I realized this because I didn't understand why the first network was only zeros in the last octect, but the first network that uses the third octect starts with a 1 instead of a 0

#

but now everything makes sense uwu

I am pissed, I just tried to tune a string on my guitar up ONE note, and it snapped

#

How long should guitar strings be replaced regularly anyway? Because I bought the current ones (one of which just broke) at the beginning of January.

#

Follow up question, can anyone recommend some good Light/Medium guitar strings for an acoustic guitar? XD

keen sequoia
#

It depends on how much you play them, whether or not your hands are clean, acidity of sweat

#

It will also depend on the material

#

But once every 3 months is probably fine if you're playing a moderate amount

#

I had a professor who went through $800 in strings a year whatthink

#

he used fairly expensive strings, as I recall

main hatch
#

Damn, I’m just using cheap strings off of amazon atm XD

keen sequoia
#

Honestly guitar strings are cheap, and there are good ones for cheap

#

Violin strings can run you upwards of $100, though they typically last much longer

main hatch
#

Ha, that’s how much I paid for my guitar

keen sequoia
#

I'm not particularly well versed in traditional steel string acoustic, so I can't really provide many suggestions other than that you try some and decide which suits you best.

main hatch
#

I’m probably just gonna reorder the same strings I got last time because I guess if they lasted 4 and a half months, they were alright

keen sequoia
#

You can google around for what type of strings people playing whatever genre you prefer use, and jump around from there.

#

For the most part, especially early on, one set of strings is going to be as good as any other

main hatch
#

Alright, thanks

main hatch
#

I had a little bit of that size string left over that I had clipped off when I stringed it the first time. So I just tied it together to extend it a bit so it would reach the turret and I could tighten it back up

Tbh, I did the same thing last time a string broke until I could order some replacements

Haha that's what I was referring to

I just wasn't paying attention to how I was naming them

@vestal pine you got the silver medal

#

Yay

what does it mean to be deprived

still radish

you wouldn't know

#

oye, i have a question for the programmers

still radish
#

we're not short on those

copper fox
#

so im really interested in starting to learn about algorithms on Khanacademy

#

but would it be better if i start learning a programming language first

still radish
#

well I guess algorithms are different to programming

#

that's mathematics

copper fox
#

since you mostly apply algorithms while coding. i mean, you do it irl as well but not as categorically and not in an organized way really

still radish
#

programming languages are a way to implement an algorithm

copper fox
#

yeah but would i be able to understand them better if i knew about programming

fossil cipher
#

How do you want to do algorithms if you can't code?

copper fox
#

or is it more vice versa

still radish
#

but really an algorithm is a mathematical construction

#

I studied algorithms 5 years before I learned any programming

#

we all did in maths class

fossil cipher
#

Then it depends on what he wants to do with them

copper fox
#

not necessarily do algorithms, just to be able to understand how they're made and how they're applied in a logical sense

still radish
#

but it probably is a good idea to start programming along side

#

to practise putting the ideas you learn into practice

#

In graph theory, a branch of mathematics and computer science, the Chinese postman problem, postman tour or route inspection problem is to find a shortest closed path or circuit that visits every edge of an (connected) undirected graph. When the graph has an Eulerian circuit ...

Gracias huevo

still radish
#

depending on your persuasion you might find stuff like this cool

hollow wedge
#

I would recommend trying both out, they complement each other, if the goal is to learn both eventually

#

note that to be a programmer you don't really need to know a lot a bout algorithms, although it can be very useful sometimes.

still radish
#

oh absolutely. the number of people that need to do real mathematics (i.e. intellectual work) is tiny. the rest of us are just cogs in a machine

#

and that's fine

ashen mist
#

alguien dijo mathemáticas?

hollow wedge
#

the thing I most often use from algorithms is time complexity "intuition"

still radish
#

basically approximately how long will this take to run? @hollow wedge

hollow wedge
#

or like, if I have to do this with more than a handful of items will it take forever?

still radish
#

OK got you. It's pretty easy to write a program that runs forever

#

I remember when I was trying find prime numbers

#

I started by just iterating over literally every number and checking it's factors lmao

hollow wedge
#

I remember I did one like that, but I first checked if it was divisible by the first couple of primes

#

every time I improved it, I just added another prime to check for before doing the general check lol

still radish
#

I think the fastest method is a sieve

#

well actually

#

it depends

hollow wedge
#

yeah, if you know beforehand how high you want to go there are different methods too

severe vortex
#

Yeah as a programmer you don't need to know exactly how algorithms work, you just need to know that they exist and when you should use them

#

Cause all the most common algorithms have already been written a million times in a million ways in a million languages

big O notation

#

print out the names of items in a list - scales linearly with your list size
print out the unique pairs of items in a list - scales quadratically with your list size

#

I don't understand how abstract classes work in Java

fallow dock
#

something in particular?

median trail
#

well... I just don't

#

in general

fallow dock
#

the idea of anything "abstract" in programming is that you're supposed to inherit from implement it yourself first, instead of instantiating it directly

#

so if you have an abstract class of LivingBeing, you can't make a LivingBeing directly

#

but you can have a Human that inherits it

#
abstract class MyAbstractClass {
    void method() {
        System.out.println("Hello");
    }

    abstract void eat();
}

class Child extends MyAbstractClass {
    @Override
    void eat() {
        System.out.println("Om nom nom");
    }
}

public class Exmaple {
    public static void main(String[] args) {
        // this isn't allowed:
        // MyAbstractClass abc = new MyAbstractClass();

        Child child = new Child();
        child.method();
    }
}```
#

it goes kinda like this

still radish
fallow dock
#

I can't new MyAbstractClass();, but I can implement a Child class that's MyAbstractClass

still radish
#

what is this wizardry... you can create children?

fallow dock
#

no, I'm sterile

#

and when it comes to abstract methods - you need to implement them as well

still radish
fallow dock
#

you can't extend MyAbstractClass without implementing eat()

I'm gonna read this later on thank youwuwuwuwuwuw

@median trail es como un "template"

#

No tiene sentido tener una plantilla vacía, así que para usarla tenés que rellenarla

median trail
#

I just don't understand why when we are using interfaces we can just use call the GUI attributes without instantiating

ashen mist
#

GUI attribute?

median trail
#

yeah like let's say I have a class called GUIPeople, and it stores people in an attribute called people, inside a different class I can use GUIPeople.people

#

and get the info stored in people

ashen mist
#

Y dónde está la interfaz?

median trail
#

they are all in the same project

ashen mist
#

No recuerdo si en Java hay class variables

median trail
#

no, my teacher told me it's related to abstract classes

fallow dock
#

I don't quite understand what the classes and instances are in your program

ashen mist
#

Me encanta que los nativos de español hablen en inglés con este tema jaja

fallow dock
#

could you give us a minimal reproducible example?

#

maybe by "without instantiating" you mean "without setting the fields from the inherited class"?

#

like so:```java
abstract class ABC {
String text = "Hello";
}

class ChildOfABC extends ABC { }

public class Whatever {
public static void main(String[] args) {
ChildOfABC child = new ChildOfABC();
System.out.println(child.text); // -> "Hello"
}
}```

median trail
#

okay I don't have an example but I can tell you what I wanna do

#

I have to classes that extends JFrame

#

and one of them stores people

fallow dock
#

oh noes Swing

median trail
#

but I want the other to get what's stored in the variable that stores people

#

which is an attribute in the other class

#

and my teacher did something weird

#

(I forgot to mention that both interfaces belong to a main interface like a menu)

#

and my teacher told me I had to create a method in the class that stores people

#

and by using it I can get this info in the other interfaces

#

and what I remember she did was to literally do classThatStoresPeople.getPeople()

getPeople returns the attribute that stores people

#

let's say I have this

fallow dock
#

if that classThatStoresPeople is actually a class, then getPeople is static

median trail
#

but I want the people stored in IngresoPersonasGUI to be in the main interface

#

(IngresoPersonasGUI has an attribute called personas)

fallow dock
#

I'm not 100% sure I'm following

#

those two classes that extend JFrame could also share an interface to pass the data you want between them. Or you could make them share a common ancestor

#

like

#

I don't see how this is related to abstract classes at all

median trail
#

LOL YOU ARE RIGHT

#

A STATIC METHOD SUFFICED

#

wait what the fuck

#

I don't understand this

#

okay let me make sure we are both on the same page

#

I'm gonna show you

fallow dock
#

I wouldn't use a static method for this, unless you declare in in a sort of God class

median trail
#

this is the mainGUI

#

when I click RegistrarPersonas

#

the code above runs

#

and displays this

#

and I'm gonna put 1 in every text field and store it

#

done

#

then I close this interface

#

and click mostrar personas

#

which runs this piece of code

#

it's stored

#

I mean I haven't changed the toString method

#

of personas

#

but you understand

#

but

#

I don't even understand why this is possible
