A brief look into HTTP, HTTPS, and APIs
Published: 2023-01-22 04:21:33

## **Introduction**
When it comes to the internet, there are a lot of different terms and technologies that can be confusing for beginners. Two of the most common terms you might have heard of are HTTP, HTTPS, and APIs. In this blog post, we'll explain what these terms mean and how they relate to each other.

## **What is HTTPS?**

HTTP stands for Hypertext Transfer Protocol. It can be called the backbone of the internet. It follows the basic client-server model. You send the request that means you are a client and the server responds to it by providing corresponding resource. As simple as that. 

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/c7q13csksg9gebhirtrp.png)

Another important thing to note is that HTTP is stateless. What it means is that, every transaction you make is independent and not related to any other transactions. 
In the OSI model, HTTP comes under the application layer protocol.

## **How is HTTPS different from HTTP?**
HTTPS is simply an extension of HTTP. It stands for Hypertext Transfer Protocol Secure. The main difference between HTTP and HTTPS is that HTTPS uses SSL (Secure Sockets Layer) or TLS (Transport Layer Security) to encrypt the data being transferred. This means that if someone intercepts the data, they won't be able to read it. HTTPS is often used for sites that handle sensitive information, such as online banking or shopping sites.

## **What are APIs?**
Application Programming Interface or APIs are the set of rules and protocols that allow software to communicate with each other. They provide a way for different systems to share data and functionality. 
When it comes to concept of HTTP and HTTPS, APIs play an important role. They allow web browsers and servers to communicate with each other, and enable websites and apps to retrieve and send data through HTTP or HTTPS requests. For example, when you enter a search query on a website, the website's backend code sends an HTTP or HTTPS request to an API on a server, which then retrieves the relevant data from a database and sends it back to the website in the form of an HTTP or HTTPS response.

## **Conclusion**
All in all APIs play a vital role in the context of HTTP and HTTPS, in terms of how data is sent and received and also how security is maintained.

OpenBSD maintenance: OS reinstall
Tags: openbsd, maintenance, install, upgrade
Published: 2023-01-22 06:15:00

## Summary

The official documentation [says](https://www.openbsd.org/faq/faq4.html#bsd.rd):

> If you have a running OpenBSD system, bsd.rd is all you need to reinstall or upgrade to a newer version.

This post shows how to use `bsd.rd` above, the ramdisk kernel, to start to reinstall the OS.
Network or external media is unnecessary. Besides, in installation, it is necessary to get the file sets from any of `cdrom disk http nfs` at "Location of sets?".

## Description

Reboot the machine, enter `/bsd.rd` (or just `bsd.rd`) when `boot> ` is shown.
Well, remember the boot process will go on automatically in a short while if you don't enter anything.

![openbsd booting](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/rr87tjbnu93al2rvlr74.png)

That's it !! You will see the installer start.

![openbsd ram disk kernel installer](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/xmz89dyuqf9y2a3kzmbv.png)

## Conclusion

After installing OpenBSD once, `bsd.rd` is in your hands.
With it, you can reinstall the machine. You can also apply [full disk encryption](https://obsd.solutions/en/blog/2022/12/14/openbsd-full-disk-encryption-on-virtualbox/) via the shell beforehand.
How to Deploy a flask app using Docker
Tags: docker
Published: 2023-01-22 06:10:11

Docker is a powerful tool that makes it easy to deploy and run web applications in a containerized environment. In this blog post, we'll show you how to use Docker to deploy a Flask application.

Before you begin, make sure that you have Docker installed on your machine. You can download it from the official Docker website.

**Step 1:** Create a Flask Application First, you'll need to have a Flask application that you want to deploy. If you don't already have one, you can create a new one by following the Flask documentation.

**Step 2:** Create a Dockerfile A Dockerfile is a script that contains instructions for building a Docker image. Create a file called "Dockerfile" in the root of your application directory and add the following:

```
FROM python:3.8
COPY . /app
WORKDIR /app
RUN pip install --upgrade pip
RUN pip install -r requirements.txt
CMD ["python", "app.py"]

```

This Dockerfile tells Docker to use the official Python 3.8 image as the base, copy all the files from the current directory to the /app directory in the container, set the working directory to /app, install the application dependencies, and run the command "python app.py" to start the application.

**Step 3:** Build the Docker Image Once you have your Dockerfile ready, you can build the Docker image by running the following command in the terminal:


`docker build -t myapp .`

This command will build the image and tag it as "myapp".

**Step 4:** Run the Docker Container Once the image is built, you can run the container by executing the following command:

`docker run -p 5000:5000 myapp`

This command will start the container and map port 5000 on the host to port 5000 in the container. This means that your application will be accessible on http://localhost:5000.

**Step 5:** Deploy to a Remote Server To deploy your application to a remote server, you can use the Docker push command to push the image to a registry such as Docker Hub or a private registry, and then use the Docker pull command on the remote server to pull the image and run the container.

In conclusion, Docker is a powerful tool that makes it easy to deploy and run web applications in a containerized environment. By using a Dockerfile and building a Docker image, you can easily package your application and its dependencies and deploy it to any environment.

How to Create Modal Popup in React JS
Published: 2023-01-22 06:01:02

In this article you will learn how to create [popup box using React](https://foolishdeveloper.com/how-to-create-modal-popup-in-react-js-free-code/). Earlier I have shared many popup window and **automatic popup box** tutorial using html css and javascript.

In React JS, you can create a Popup component that can be reused throughout your application. 

The basic idea is to have a state variable that keeps track of whether the popup should be visible or not and a function that toggles this state.

Here's an example of how you can create a **simple Popup component in React JS**:

```js
import React, { useState } from 'react';

function Popup({ children }) {
  const [isOpen, setIsOpen] = useState(false);
  return (
    <>
      <button onClick={() => setIsOpen(true)}>Open Popup</button>
      {isOpen && (
        <div className="popup">
          <div className="popup-content">
            {children}
            <button onClick={() => setIsOpen(false)}>Close</button>
          </div>
        </div>
      )}
    </>
  );
}

export default Popup;

```
In this example, the Popup component uses the `useState` Hook to manage the state of the popup. It has a state variable `isOpen` that is initially set to `false` and a setIsOpen function that toggles the state. 

The component renders a button that calls the `setIsOpen` function with a value of true when clicked, which opens the popup. 

The component also renders the children passed to it, and a close button that calls the setIsOpen function with a **value of false when clicked**, which closes the popup.

You can use this component in other parts of your application by importing it and passing any content you want to display inside the Popup as children, like so:

```php
import Popup from './Popup';

function App() {
  return (
    <Popup>
      <h2>Popup Title</h2>
      <p>Popup message goes here</p>
    </Popup>
  );
}

```
The code you provided is an example of how you can use the Popup component in your application. 

The **App function renders the Popup component** and passes any content you want to display inside the Popup as children.

It's important to note that this is a basic example and it's necessary to customize the design and functionality to fit your needs, also you can use some libraries like react-modal or react-overlays to have more powerful functionalities.

Understanding and Using the useContext Hook in React
Tags: react, webdev, javascript, reacthooks
Published: 2023-01-22 05:47:38

The `useContext `hook in React allows a component to access data from a context object without having to pass props down through multiple levels of the component tree. This can make the component structure of a React application more efficient and easier to understand.

To use the `useContext `hook, a context object must first be created using the `createContext` function. This function takes an initial value as an argument, which will be the value of the context when it is first accessed by a component.


```js
import React, { createContext } from 'react';

const MyContext = createContext({});
```
Once the context object has been created, it can be provided to a component tree using the `Provider `component. This component takes a value prop, which is the current `value `of the context.


```js
import { MyContext } from './MyContext';

function App() {
  return (
    <MyContext.Provider value={someValue}>
      {/* component tree */}
    </MyContext.Provider>
  );
}
```
Any component that is a child of the `Provider `component can access the context value using the `useContext `hook. The hook takes the context object as an argument and returns the current value of the context.


```js
import { MyContext } from './MyContext';

function ChildComponent() {
  const contextValue = useContext(MyContext);

  return <div>{contextValue}</div>;
}
```
The `useContext `hook also allows a component to update the context value by providing a new value to the `Provider `component. When the context value is updated, all components that are using the context will re-render with the new value.


```js
import { MyContext } from './MyContext';

function App() {
  const [contextValue, setContextValue] = useState({});

  return (
    <MyContext.Provider value={contextValue}>
      <button onClick={() => setContextValue({ ...contextValue, newProp: 'newValue' })}>
        Update Context
      </button>
      <ChildComponent />
    </MyContext.Provider>
  );
}
```
In summary, the `useContext `hook in React allows components to access and update data from a context object without having to pass props down through multiple levels of the component tree. This can make the component structure of a React application more efficient and easier to understand.
Docker Network Limits
Published: 2023-01-22 05:42:06

**Problem:** I ran into a hard limit of docker networks today and went on the hunt for a solution. In theory this should work by giving me an extra 255 items (The solution does work just not sure the exact number of networks it exposed). Otherwise I would need to consolidate my containers to use a similar network and I'm not quite ready to take that plunge.

**Solution**:
Edit /etc/docker/daemon.json

```
{
   "default-address-pools": [
        {
            "base":"172.17.0.0/12",
            "size":16
        },
        {
            "base":"192.168.0.0/16",
            "size":20
        },
        {
            "base":"10.99.0.0/16",
            "size":24
        }
    ]
}

C++ da munosabat operatorlar va mantiqiy operatorlar
Tags: true, false, cpp, beginners
Published: 2023-01-22 03:33:08

   Bu maqolamiz ham qisqaroq bo'ladi chunki unchalik ham qiyin emas.

Demak boshladik munosabat operatorlari bu ikki tomonning ya'ni chap va o'ng tomonning bir biri bilan munosabati haqida. Bu operatrolar matematika bilan bir xil emas.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/zs9dgif1s1y5vfy6h0fn.png)
Yuqorida barcha munosabat operatrolari ko'rsatilgan.
1) a<b bu belgi chap tomon o'ng tomondan kichkina ekanligini bildiradi.
2) a<=b bu chap tomon o'ng tomondan kichik yoki tengligini bildiradi.
3) a==b bu chap tomon bilan o'ng tomon tengligini tekshiruvchi amal.
4) a>= bu chap tomon o'ng tomonda katta yoki tengligini bildiradi.
5) a>b bu chap tomon o'ng tomondan kattaligini bildiradi.
6) a!=b bu chap tomon o'ng tomon bilan teng emas degani.

Mantiqiy operatorlar ga o'tadigan bo'lsa. Quyidagi rasmga qarang.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ovef28fpk5d860jrowe8.png)
Rasmda ko'rganizdek 1-qatorda **&&** belgi **va** deb tarjima qilamiz. Misol bilan tushintiradigan bo'lsak x=6 va y=3 qiladigan bo'ladigan bo'lsa _x<10 && y>1_ qilib yozadigan bo'lsak chap tomon ham o'ng tomon ham bajarilishi shart. Ya'ni true qiymat qaytarishi kerak.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/w02bc8vekmvurf5kin45.png)
Mana rasmda ikki tomon ham shartga javob bergani uchun 1 qiymay qaytardi yani true qiymat qaytardi. Agar ikki tomondan bitta tomon false bo'lb qolsa ham umumiy false qiymat qaytaradi.


 Endi huddi shu misolni yoki amali bilan sinab ko'rsak ham bo'ladi. _x<10 || y>4_ bu ko'rinishda kamida 2 tomondan bittasi true qiymat qaytarsa bo'lgani. 

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/jjsx5lu7n5ceu7n28b71.png)
Bu rasmda esa chap tomon shartga javob berdi o'ng tomon esa javob berolmadi lekin baribir 1 qiymat qaytardi yani true qiymat qaytardi. Agar chap tomon ham o'ng tomon ham shartga javob bermasa falsa qiymat qaytaradi.
Shu bilan bugungi maqolamizni ham yakunlaymiz. Foydali bo'ldi degan umiddaman.

What are hooks in WordPress?
Tags: wordpress, webdev, javascript, beginners
Published: 2023-01-22 04:44:49

## What are WordPress hooks?
WordPress hooks are a method for one piece of code to modify the behavior of another piece of code. They allow you to change how WordPress behaves without changing the core code itself. There are two types of hooks: actions and filters.

## Types of WordPress hooks
There are two types of WordPress hooks: actions and filters.

**Actions hook:**
Actions hook allow you to insert additional code at specific points referred to as “hooks” throughout WordPress. For example, you can use an action to send an email or create a widget. 

**Filters hook:**
Filters hooks allow you to modify existing code in WordPress. For example, you might use a filter to modify the content of a post before it is displayed or to change the post excerpt length of a WordPress site.

**Here are some examples of action hooks:**
**wp_head**: Executed within the `<body>` element of the page
**wp_footer**: Executed at the end of the page, before the `</body>` closing tag
**publish_post**: Executed when a post is published
**delete_user**: Executed when a user is deleted

And here are some examples of filter hooks:

**the_title**: Modifies the title of a post
**the_content**: Modifies the content of a post
**wp_mail_from**: Modifies the “from” address for emails sent by WordPress
**excerpt_length**: Modifies the length of post excerpts

There are many more action and filter hooks available in WordPress, and you can find a complete list in the WordPress Codex.
