Adapted Peru president Christmas carol

https://www.youtube.com/watch?v=Fq2we9NxCpY

English traslation lyrics for an adapted Christmas carol about the President of Peru

«My card says I only have one dose, and the registry says I can’t get vaccinated.

I can’t go buy a small gift for Christmas,
I can’t go to a pharmacy, I can’t go to the bank,
I can’t buy food,
Not even a small gift for Christmas.

If I got sick, I couldn’t go to any hospital,
Because my card says I only have one dose,
And the registry says I can’t get vaccinated.

Vizcarra can’t buy even a small Christmas gift.
Vizcarra can’t buy even a small Christmas gift.

That’s why, and for many other things,
Give Vizcarra one more dose.»**»

Spanish lyrics for an adapted Christmas carol about the President of Peru

«mi carné dice que tengo solo una dosis y el padrón dice que no me puedo vacunar

no puedo ir a comprar un pequeño presente , por navidad

no puedo ir a una farmacia , no puedo ir al banco , no puedo ir a comprar alimentos

incluso un pequeño presente por navidad

si me enfermara no puedo ir a ningún hospital porque mi carné dice que tengo solo una dosis y el padron dice que no me
puedo vacunar

vizcarra no puede comprar ni un pequeño regalo de navidad

vizcarra no puede comprar ni un pequeño regalo de navidad

por eso y muchas cosas denle a vizcarra una dosis más

«拉丁美洲，一个没有腿却依然行走的人民»大流行

发达国家

医疗、教育和交通系统

秘鲁成为全球 COVID 死亡率最高的国家

3300 万人口中，COVID-19 导致了 20 万人死亡

为了让人们待在家里，由于疫情，政府决定推迟开学。但是人们认为这就像是额外的假期，于是大多数人去了海滩，海滩上挤满了人

一个原因是由于人们的文化，他们不太听话。

在那个时刻，许多人意识到，当第一个感染病例确认时，病毒很快就会扩散，总之，很短的时间内就会变成一场灾难

那么，如果有一件事我们不会忘记那就是当时的总统

中国现在仍然是男权主义吗？

在我的国家也是，男女之间的平等仍未实现，虽然比以前好多了，证明这一点的是我们现在的总统是女性。

你为什么认为那位总统难以忘记？

事实上，他在疫情期间的管理是个灾难，但并非全是他的错，人民也有一半的责任。我们不知道是不是他的主意，或者是别人的主意，但他采取了一个非常有趣的措施来遏制COVID-19的传播。

主要是因为很多男人认为厨房是女性的事，在秘鲁也是这样，特别是我父亲那一代的人。例如我的叔叔们，尽管我从未问过他们，我相信他们一生中从未做过饭。

如果一个男人做饭或去市场购物，其他男人，比如他的朋友或同事，会对他说一些嘲笑的话吗？

冠状病毒：秘鲁限制按性别出行以遏制传播。男性和女性在不同的日子外出，而在周日，每个人都必须待在家里。

星期一、星期三和星期五只有男性可以出门，且只能去购物。

街头采访非常有趣，当然，女性们都非常赞同并感谢总统，因为尽管这只是一个小小的步骤，但对性别平等非常重要。

因为在许多家庭中，仍然是男人提供经济支持，许多家庭仍然非常贫穷，只能靠日常工作维持生计。很多妻子抱怨钱不够，这确实是事实，有时母亲不得不付出巨大的努力才能确保钱足够买食物养活孩子。有时男人对此不感兴趣，回到家里只是说‘别烦我，我累了’，这是一种悲哀的现实。所以在那个时候，许多女性认为让男人去市场买东西，用她们拿到的相同的钱买食物，是一种公平的行为，‘我希望你用20索尔买四个人的食物，包括早餐、午餐和晚餐’。

显然，女性会仔细查看购物清单，并拒绝任何不合适的购买

有一句母亲常说的话，这意味着你被购物欺骗了，买了一些如此糟糕的东西，以至于它不算是购买，更像是一个礼物。

这张图片的意思是，如果你一个人住，想在星期一和星期三出门购物，你可以穿男装，而在星期三和星期五穿女装。

这是一个网络迷因，因为对于那些不常购物的人来说，很难分辨香菜和芫荽的区别

星期一、星期三和星期五是男人出门购物，星期二、星期四和星期六是女人出去退掉男人买错的东西

你认为这个措施有结果吗？我认为没有，但确实有一些有趣的事情，比如，女性出门的日子，感染人数比男性出门的日子要高。

你为什么这么认为？嗯，显而易见的答案是，当女性去市场购物时，如果碰到朋友或熟人，她们会停下来聊天，而男性则不太会这样做

我记得在一次采访中，当有人问一个水果摊贩她最喜欢哪几天时，她说是星期一、星期三和星期五，也就是男人出门的日子。她说，因为男人不太挑剔，买东西比较快，而女性对什么都不满意，总的来说，欺骗男人反而更容易。

如果你不遵守政府实施的这一措施，他们会把你带到警察局并罚款

All the versions of JDK come bundled up with the JRE (Java Runtime Environment). This way, a user doesn’t have to download and install JRE on their PC separately.

https://docs.oracle.com/javase/specs/jvms/se21/html/jvms-4.html

check the major version for your JAVA code (the java class file)

65 is the major version , correspond to JAVA-21

you HAVE TO READ RUNNING.TXT , located in tomcat/

JRE_HOME or JAVA_HOME , required , not both , so simple solution , just delete JRE_HOME , altough some servlet tutorials (almost all) lead you to set up both .

if you find is neccesary set up both of them , this is the proccess , at final i give you some advices if nothing of these works ….

check our environments variables , this is the reason of our problem

we can comprobe just looking in our apachetomcat initialization

to solve you should JAVA_HOME == JRE_HOME , i mean have to be the same both jdk-21

JRE_HOME= xxx.yyyy.zzzz/jdk-21

check the current Java version load by server in in manager/html

admi user admin password is not the default one , have to config in tomcat-users.xml

  <user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-gui,admin-script"/>

now , launch again tomcat server

install apache tomcat as a SERVICE is not the same that execute by startup.bat , just for test purpose you unistall the service one , and download a zip one , then launch it using startup.bat located at bin folder , indeed you can use both , just need to change the ports , but i suggest you foor test purpose unistall one of them

interface MyInterface {
	void sayHello();
}

class ClassOne {
	static void methodThatCallInterfaceMethod(MyInterface i) {
		i.sayHello();
	}
}

class ClassTwo implements MyInterface {
	static void sayGoodBye() {
		System.out.println("hi - for METHOD REFERENCE CALLING");
	};

         @Override
	public void sayHello() {
		// TODO Auto-generated method stub
		System.out.println("Good Morning FROM CASS THAT DIRECTLY IMPLEMENTS INTERFACE ");
	}

	MyInterface getMyInterface() {
		return this;
	}
}

class ClassThree {
	static ClassTwo getInstanceOfClassTwo() {
 		return new ClassTwo();
	}
}

public class Main implements MyInterface {
	public static void main(String[] args) {
		Main InstanceOfMain = new Main();
		//METHOD 1
		InstanceOfMain.methodThatServeAsABridgeToExecuteinMainStaticMethod();
		//METHOD 2
		ClassOne.methodThatCallInterfaceMethod(new Main());
		//METHOD 3
		ClassOne.methodThatCallInterfaceMethod(new MyInterface() {
			@Override
			public void sayHello() {
				// TODO Auto-generated method stub
				System.out.println("Good morning from INNER CLASS");
			}
		});
		//METHOD 4
		ClassOne.methodThatCallInterfaceMethod(() -> System.out.println("Hi from LAMBDA IMPLEMENTATION"));
		//METHOD 5
		ClassOne.methodThatCallInterfaceMethod(ClassTwo::sayGoodBye);
		ClassTwo InstanceClassTwo = new ClassTwo();
		//METHOD 6
		ClassOne.methodThatCallInterfaceMethod(InstanceClassTwo);
		//METHOD 7
		ClassOne.methodThatCallInterfaceMethod(InstanceClassTwo.getMyInterface());
		//METHOD 8
		ClassOne.methodThatCallInterfaceMethod(ClassThree.getInstanceOfClassTwo());
		MyInterface instanceCreatedToStoreAnnonymousInnerClass = new MyInterface() {

			@Override
			public void sayHello() {
				// TODO Auto-generated method stub
				System.out.println("hi from ANNONYMOUS INNER CLAS ASIGNED TO VARIABLE");
			}

		};
		ClassOne.methodThatCallInterfaceMethod(instanceCreatedToStoreAnnonymousInnerClass);
		ClassOne.methodThatCallInterfaceMethod(()->InstanceOfMain.methodInsideMainClass());
		
	}
	void methodInsideMainClass () {
		System.out.println("hi from CLASS INSIDE MAIN CLASS");
	};

	void methodThatServeAsABridgeToExecuteinMainStaticMethod() {
		ClassOne.methodThatCallInterfaceMethod(this);
	}

	@Override
	public void sayHello() {
		// TODO Auto-generated method stub
		System.out.println("hi from Main INSIDE CLASS");

node -v ### to verify correct installation

npm -v

right click on shell icon > properties > «start in»

this is the deafualt starting «start in» folder : «%HOMEDRIVE%%HOMEPATH%»

after instal vim , there is a problem to launch vim from command prompt

we have to add a path to our user variables , first have to find folder where is our vim executable …

go to «environment variables»

edit «path» in user variables , ADD the folder where is you vim executable (there many other paths inside )
