Is this a legal loophole in obtaining Premium membership to Youtube?

I think a person can have multiple Google accounts. This means that the same person can create a new Gmail account every month just to be able to continue accessing the free premium Youtube subscription for a month. Is it in a sense a "legal loophole" that someone can exploit?

Just to clarify, this is not something I want to do. It's just a question that comes to my mind and I want to know the answer.

numbers – Obtaining the historical exchange rate via CURRENCYH displays an error: the requested historical date is not valid or is future

From the Apple Number doc, the formula CURRENCYH should return historical currency data.


= CURRENCY ("USD", "GBP", 3, "04/18/2017") returns £ 0.78, the lowest exchange rate ("low" or 3) of the US dollar (USD) at
British pounds (GBP) on April 18, 2017.

= CURRENCY ("gbp", "bmd", "open", "12/31/2015") returns BMD1.48, the exchange rate from the British pound (GBP) to the Bermudian dollar (BMD)
at the start of negotiations on December 31, 2015.

= CURRENCYH ("usd", "aud", "close", TODAY () – 2) returns the exchange rate from the US dollar to the Australian dollar (in AUD) at the close
to negotiate two days ago.

However, when I try it with TODAY()-2 (wrote May 4, 2020) and a few days before, it shows the error The requested historical date is not valid or is future.


Today () - 2

I have to return 4 Apr 2020and the error message has become There is no historical data as of the requested date. The next available is 04/06/2020.


After updating to 6 Apr 2020, I managed to get the USDGBP rate and everything is available until 17 Apr 2020, then became unavailable.


To summarize with a quick test from April 1:

  • April 1-3 are available
  • April 4-5 are DO NOT available
  • April 6-17 are available
  • April 18 – May 4 are DO NOT available

It seems very unreliable to get the exchange rate for a specific date in numbers. Is it planned and how can I fix it?

c ++ – Obtaining the error `reference not defined at & # 39; glfwOpenWindowHint & # 39; & # 39; when attempting to run the OpenGL SuperBible code sample on Linux

I'm completely new to C ++ so please be gentle with me.
I am trying to expose the OpenGL SuperBible 6th edition example code for the first time on my Manjaro system (arch).
I followed the HOWTOBUILD.txt, installed mesa and glfw (glfw-wayland, I don't know if there is a difference) via pacman. I tried to run the first time without success, then changed an error in the CMakeList.txt as described here
he got rid of the undefined reference to 'glfwInit' error, but all other undefined errors remained.

code example:

numerical integration – Obtaining the function volume with double integrals in Mathematica

Integral detected

I want to get the volume of a function with a double integral. To fix this, you need to evaluate against x + -sqrt (y-y ^ 2) but when I try to replace it, I get this error:


Sqrt (y - y ^ 2) is not a valid integration limit

NIntegrate (func1, {x, -Sqrt (y – y ^ 2), Sqrt (y – y ^ 2)}, {y, 0, 1})

Sqrt (y - y ^ 2) is not a valid integration limit

NIntegrate (func2, {x, -Sqrt (y – y ^ 2), Sqrt (y – y ^ 2)}, {y, 0, 1})

My code:

func1 = 1 – y ^ 2 – x ^ 2

func2 = 1 – y

NIntegrate (func1, {x, -Sqrt (y – y ^ 2), Sqrt (y – y ^ 2)}, {y, 0, 1})

NIntegrate (func2, {x, -Sqrt (y – y ^ 2), Sqrt (y – y ^ 2)}, {y, 0, 1})

NIntegrate is the only way I can find to solve an integral double and get a numeric number, but I can't use these limits

Is there a way around this error?

Problems Obtaining Adsense Approval

Hi guys, I'm a new member so please be gentle with me. I have been trying to get my site,, approved for AdSense for some time. Unfortunately, every time he is pushed back with his standard response to check the "sites" page. This page always directs me to their policy violation.

My problem is that I feel like I have covered all the basics, but I must be missing something. It would be so much easier if the Adsense team could tell me precisely what I need to fix.

I hope someone on this forum can help you. I have tried the Adsense forum, but they do not allow questions which are absurd given that it is a forum

oracle – Java pool setting after obtaining ORA-04031

I am using Oracle Standard Edition on Windows 2012 RC2.
I am NOT performing automatic memory management in Oracle.

We see them in the alert log:

ORA-04031: unable to allocate 4096 bytes of shared memory ("java pool","prv//////LBKLAGIMAAAAAAAA","JOXLE^aff7380e",":SGAClass")

The first thing I thought of trying was to empty the shared pool to fix the immediate problem, while the development team fixes the SQL code, so I executed:


It was only then that I realized that the Java pool is not actually part of the shared pool. So I tried to take a look at the Java pool.

I think that tells me that my Java pool is around 32MB:

SQL> select * from v$javapool;

CATEGORY                                            MEMUSED     CON_ID
------------------------------------------------ ---------- ----------
:Intern                                              973440          0
:SGAClass                                          32103240          0

I have run this tuning tool, which, if I can interpret it correctly, says that there are not many benefits in increasing the size of the Java pool:


------------ --------------------------- ---------------------
           8                          16                    .5

          25                          48                   1.5
          25                          64                     2
          25                          80                   2.5
          25                          96                     3
          25                         112                   3.5
          25                         128                     4
          25                         144                   4.5
          25                         160                     5
          25                         176                   5.5

I can see that SGA_TARGET = 4928M and JAVA_POOL_SIZE = 0, so I am a little confused on how to fix this when we are not using AMM.

So how do you solve this problem?

  1. is my best option to increase the size of the Java pool?
  2. if so, what to do when you are not using AMM?

unit – Obtaining an error when I send a message to the RaycastHit object

I created a shooter, here when I shoot, I have an ac # script for enemy damage. I used Raycast to shoot enemies. If the RaycastHit becomes an enemy , it will be deducted from its health. It is working properly. But the thing, if I shoot at objects except enemies, it causes an error.
I have provided some details on this. Here is the script,

public class DamageSMG : MonoBehaviour
    public int DamageAmount = 5;
    public float TargetDistance;
    public float AllowedRange = 50;
    public RaycastHit Shot;
    public int Firing;
    void Update()
            if (Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward),out Shot))
                TargetDistance = Shot.distance;
                if (TargetDistance < AllowedRange)
                    if (Firing == 0)
    public void Deduct()
        Firing = 1;
        Shot.transform.SendMessage("DeductPoints", DamageAmount);

    IEnumerator Wait()
        yield return new WaitForSeconds(0.1f);
        Firing = 0;

I'm using a machine gun, so I created Script to shoot with custom with a 0.1 second pause. Fire 1 , the RayCastHit object receives a message in which the method called DeductPoints with the DamageAmountLike this script, my enemies deduct the point 5 by 5 with each stroke. Then destroy the object. The enemy script is as follows.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class EnemyScript : MonoBehaviour
    public int EnemyHealth = 20;
    void DeductPoints(int DamageAmount)
        EnemyHealth -= DamageAmount;

    // Update is called once per frame
    void Update()
        if (EnemyHealth <= 0)
            GlobalScore.GlobalScorecount += 1;



But my problem is when I shoot objects except enemies (Ex: walls), the console gives an error. The error is like that
SendMessage DeductPoints does not have a receiver
How can I fix this error or is there another way to infer the health of the enemy with raycast?
I can play the game with this error in UnityEngine. But it is not possible to build the game. Please help me to solve this problem.

digital integration – FEM: obtaining the resulting electric force on each body from the electric field

Based on this excellent FEM response: Electric field between two arbitrarily defined forms, I can calculate the electric field ef between two conductive objects.

enter description of image here

$$ F = qE $$
Now I have tried to calculate the total resulting electric force on each object (acting at the geometric center), by simply integrating the electric field around the border of the object:

 Evaluate(ef), {x, y} (Element) 
  Region`RegionProperty(RegionBoundary(object1), {x, y}, 

but it does not work. Any help would be greatly appreciated.

Here is the complete code to calculate the electric field:

(*Define Boundaries*)
air = Rectangle({-5, -5}, {5, 5});
object1 = Rectangle({-2.5, 2.5}, {2.5, 2});
object2 = Rectangle({-2.5, -2.5}, {2.5, -2});
reg12 = RegionUnion(object1, object2);
reg = RegionDifference(air, reg12)

mesh = ToElementMesh(reg, MaxCellMeasure -> 0.1);

eq = Laplacian(u(x, y), {x, y}); V1 = 1; V2 = -2;
bc = {DirichletCondition(u(x, y) == V1, 
    Region`RegionProperty(RegionBoundary(object1), {x, y}, 
   DirichletCondition(u(x, y) == V2, 
    Region`RegionProperty(RegionBoundary(object2), {x, y}, 
U = NDSolveValue({eq == 0, bc}, u, {x, y} (Element) mesh);

ef = -Grad(U(x, y), {x, y});

StreamDensityPlot(Evaluate(ef), {x, y} (Element) reg, 
 ColorFunction -> "Rainbow", PlotLegends -> Automatic, 
 FrameLabel -> {x, y}, StreamStyle -> LightGray, VectorPoints -> Fine,
  PlotRange -> Automatic)
