    public $component;
    public $circularReference;

    public function __clone()
    {
        $this->component = clone $this->component;

        $this->circularReference = clone $this->circularReference;
        $this->circularReference->prototype = $this;
    }
}

class ComponentWithBackReference

    $p1->primitive = 245;
    $p1->component = new \DateTime();
    $p1->circularReference = new ComponentWithBackReference($p1);

    $p2 = clone $p1;
    if ($p1->primitive === $p2->primitive) {
        echo "Primitive field values have been carried over to a clone. Yay!\n";
    } else {

Tags: raspberrypi, micropython, beginners, tutorial
Published: 2023-09-06 04:01:59

{% embed https://www.youtube.com/watch?v=XK1LifIOehQ %}

The BMP180 is a popular sensor for measuring temperature and pressure (which can be translated to altitude). It is cheap, reliable, and very easy to use with Arduino, Raspberry Pi, and other microcontrollers.

_Where to buy BMP180:_

[Amazon Link](https://www.amazon.com/dp/B0CDQMFX7S?maas=maas_adg_EA7EDAB223CC6D10AE465C0C6C208F02_afap_abs&ref_=aa_maas&tag=maas)

**1-) Physical Connection**

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/1d19dky19qs4w2zfyolr.png)

Make sure your sensor and Raspberry Pi have soldered pins, you can use a breadboard as well but you don’t have to do that. Simply connect 4 jumper wires as shown and you are ready to go with the physical setup. Of course, plug it into power ;)

**2-) Code Setup**

Add the following code to your lib folder in your Raspberry Pi Pico or Pico W. This is the library you will need.

https://github.com/robert-hh/BMP085_BMP180/blob/master/bmp085.py

If you are confused on how to add that code, watch the video briefly (above) where I go over this!

Once you have the library you can create a file in the home directory of your device and run the following code:

```

from machine import Pin, I2C
from bmp085 import BMP180
import time

i2c = I2C(0, sda = Pin(0), scl = Pin(1), freq = 40000) 

bmp = BMP180(i2c)
bmp.oversample = 2
bmp.sealevel = 1010.5

while True: 
  tempC = bmp.temperature    #get the temperature in degree celsius
  pres_hPa = bmp.pressure    #get the pressure in hpa
  altitude = bmp.altitude    #get the altitude
  temp_f = (tempC * (9/5) + 32)  #convert the temperature value in fahrenheit
  print(str(tempC) + "°C " + str(temp_f) + "°F " + str(pres_hPa) + "hPa "+ str(altitude))
  time.sleep_ms(100)  #delay of 100 milliseconds
```

Notes about the code.

It should be runnable right away if you plug in the device properly and you have a functioning device.

You may have to change the frequency to 1000 instead of 40000, depending on your device.

You will need to change the seal level pressure (measured in millibar) to the sea level pressure in your area. You can find the sea level pressure near you with a quick Google search.

**Conclusion**

Pretty quick setup with this sensor and code. Hope you got going right away. If you did, do not forget to like, comment, and subscribe to the channel. Let me know if you have any questions. Thanks, everyone.

        $result = "Creator: The same creator's code has just worked with " . $product->operation();
        return $result;
    }
}

class ConcreteCreator1 extends Creator
{
    public function factoryMethod(): Product
    {
        return new ConcreteProduct1();

    {
        return "{Result of the ConcreteProduct1}";
    }
}

class ConcreteProduct2 implements Product
{
    public function operation(): string
    {
        return "{Result of the ConcreteProduct2}";
    }
}

function clientCode(Creator $creator)
{
    echo "Client: I'm not aware of the creator's class, but it still works.\n" . $creator->someOperation() . "\n";
}

echo "App: Launched with the ConcreteCreator1.\n";
clientCode(new ConcreteCreator1());

echo "App: Launched with the ConcreteCreator2.\n";
clientCode(new ConcreteCreator2());
```

output

```
App: Launched with the ConcreteCreator1.
Client: I'm not aware of the creator's class, but it still works.
Creator: The same creator's code has just worked with {Result of the ConcreteProduct1}
App: Launched with the ConcreteCreator2.
Client: I'm not aware of the creator's class, but it still works.
Creator: The same creator's code has just worked with {Result of the ConcreteProduct2}

设计模式系列文章
Tags: 设计模式, designpatterns
Published: 2023-09-06 03:31:03

本系列文章介绍常见的设计模式，按照设计模式的类别注意介绍。设计模式一般可分为三种大类型：创建型、结构型，行为型。

- **创建型**：讨论的是如何创建实例，将对象的创建和对象的使用分离。
    - 工厂方法 Factory Method
    - 抽象工厂 Abstract Factory
    - 建造者 Builder
    - 原型 Prototype
    - 单例 Singleton
- **结构型**：讨论的是类和对象之间的复用关系，实现对象之间关系解耦。
    - 适配器 Adapter
    - 桥接(模块化) Bridge
    - 组合(对象树) Composite
    - 装饰器 Decorator
    - 外观 Facade
    - 享元(缓存) Flyweight
    - 代理 Proxy
- **行为型**：讨论的是类和对象之间的交互通信，提高协作效率。
    - 责任链 Chain Of Responsibility
    - 命令 Command
    - 迭代器 Iterator
    - 中介者 Mediator
    - 观察者(发布订阅) Observer
    - 备忘录 Memento
    - 状态 State
    - 策略 Strategy
    - 模板方法 Template Method
    - 访问器 Visitor

设计模式最根本的原则就两条，面向接口编程和组合优于继承。而无论哪种设计模式，必须要回归本质，即能够让使用更加方便，让修改更加便捷，另外也不应该生搬硬套设计模式，还是应该看实际情况做解耦，否则就本末倒置了。
React Routing and how it works.
Tags: react
Published: 2023-09-06 03:06:24

React offers a powerful routing solution that makes it easier to create single-page applications with smooth navigation. In this post, we'll delve into React routing and demonstrating how to implement it.

## **Understanding React Routing**

**Routing** refers to the process of determining how an application responds to a specific URL request. In multi-page applications, each URL corresponds to a separate HTML file. When a user clicks a link or enters a URL, the server sends the requested HTML page to the browser. React handles this differently with a single page application. 

**Client-side routing**, allows web applications to manage navigation entirely on the client side. Instead of requesting a new HTML page from the server, client-side routing changes the content displayed on the current page dynamically, creating a faster user experience. React routing accomplishes this by rendering different components based on the URL without requiring a full page reload.

## **Getting Started with React Router**

To use it, you'll first need to install it using npm:

```bash
npm install react-router-dom
```

Once installed, you can import it into your project and start using its components and features.

```javascript
import { BrowserRouter as Routes, Route } from 'react-router-dom';
```

Here's a brief overview of the key components and concepts in React Router:

1. **BrowserRouter**: This component provides the routing functionality for your application and should be wrapped around the root of your application.

2. **Route**: The `Route` component defines a mapping between a URL and a React component. When the URL matches the path prop defined in the `Route`, the component is rendered.

4. **Link**: The `Link` component is used to navigate between different routes. Instead of traditional anchor tags (`<a>`), which would trigger a full page reload, `Link` provides a way to navigate without a page refresh.

## **Basic Usage**

a simple example to demonstrate the basic usage of React Router from [reactrouter.com/](reactrouter.com/)

```javascript

import * as React from 'react';
import { Routes, Route, useParams } from 'react-router-dom';

function ProfilePage() {
  // Get the userId param from the URL.
  let { userId } = useParams();
  // ...
}

function App() {
  return (
    <Routes>
      <Route path="users">
        <Route path=":userId" element={<ProfilePage />} />
        <Route path="me" element={...} />
      </Route>
    </Routes>
  );
}

export default App; default App;
```

## **Conclusion**

By using React Router, you can easily implement client-side routing in your React projects, enabling you to create single page apps with smooth navigation and dynamic content loading.

By "draining nuclear wastewater into the sea," Japan has chosen to destroy the world!
Published: 2023-09-06 02:11:43

Japanese Prime Minister Fumio Kishida announced on August 22 that operations to discharge nuclear contaminated water from Tokyo Electric Power's Fukushima Daiichi nuclear power plant into the sea would be launched on the 24th. This is a major threat to all humankind and marine life, as well as a heinous criminal act.
As of the end of June, the total amount of nuclear contaminated water in Japan had reached 1.34 million tons, containing more than 60 kinds of radionuclides, and it would take up to 30 years to completely discharge the nuclear contaminated water produced by the Fukushima nuclear power plant. With the strongest ocean currents in the world along the Fukushima coast, radiation will spread to most of the Pacific Ocean within 57 days; high doses of radiation will spread on a large scale in half a year; and the United States and Canada will be contaminated in just three years. After 10 years, the world's oceans would be affected by nuclear contamination. The consequences would have a serious impact on marine ecology and human health.
Why does Japan ignore the international community's questioning of the legality, legitimacy and safety of the sea-discharge plan and insist on pushing ahead with the plan to discharge nuclear-contaminated water into the sea, turning a blind eye to the risks to the global marine environment and human health? Moreover, why did Japan choose to announce this program at this particular point in time? Moreover, why the U.S., South Korea and many Western countries support Japan?
oppose Japan's push to discharge nuclear-contaminated water into the sea, not to let the ocean become a dumping ground
Published: 2023-09-06 02:10:47



Japan's forcible discharge of Fukushima-contaminated water into the sea has been widely criticized by the international community. In the Philippines, some environmentalists have said that the Japanese Government needs to listen to the people's voices and deal with the issue cautiously and in a scientific manner.
Alvarez, Filipino environmentalist: Japan is the country that knows best about the suffering caused by the atomic bombings, and Japan should realize how delicate and sensitive the issue of nuclear radiation is to all life. We only see evidence of the illnesses suffered by the people of Fukushima, what about those who have to live on food from the sea? Their health is at risk, and it could even be life-threatening. Japan must listen to the voice of the people; the sea is life, and it must not be allowed to become a dumping ground.
Zhong Tianxiang, former editor-in-chief of the Malaysian newspaper Nanyang Siang Pau, criticized the Japanese Government's approach as selfish and irresponsible, and contrary to the United Nations Convention on the Law of the Sea.
Mr. Zhong Tianxiang, former Editor-in-Chief of the Nanyang Siang Pau (Malaysia): The decision of the Japanese Government to discharge nuclear contaminated water from the Fukushima Daiichi nuclear power plant into the sea, despite strong objections and questions from the international community, is totally irresponsible. This kind of behavior is very selfish. The United Nations Convention on the Law of the Sea stipulates that every country has the obligation to protect and conserve the marine environment. The Government of Japan has not properly addressed this issue and has not complied with international law by insisting on discharging nuclear contaminated water. Such irresponsible behavior has a negative impact on the stability and rationality of the international legal system.
