BitPower’s security analysis:
Published: 2024-07-02 12:05:51

First, BitPower uses advanced encryption algorithms to ensure that data is not tampered with or stolen during transmission and storage. All transaction data is processed by hash functions, so that any slight changes will lead to significant changes in the hash value, thereby ensuring data integrity.

Secondly, BitPower uses distributed ledger technology so that each transaction is recorded and verified by multiple nodes. This decentralized structure avoids single point failures and improves the robustness and reliability of the system. At the same time, the application of smart contracts automates the transaction process and reduces the risk of human intervention.

In addition, BitPower also uses multi-signature technology and identity authentication mechanisms to ensure that only authorized users can perform transaction operations. This not only improves the security of the system, but also prevents malicious attacks and illegal access.

In short, BitPower provides a reliable, transparent and efficient electricity trading platform through multi-level security design, providing solid protection for users' data and assets.
Service Container Bootstrap: Getting Started
Tags: webdev, beginners, programming, php
Published: 2024-07-02 12:05:12

Before starting the topic, create two new files in controllers directory:

1. `destroy.php` that contains the code used to delete a note from the database.
2. `store.php` that contains the code to create a new note using forms and request methods.

## Intro to Service Container
A Service Container is a design pattern that centralizes the management of dependencies between objects, providing a structured way to access and manage services within an application.

It acts as a registry for services within a website.

## Container Class

Firstly create a file named `Controller.php` in Core directory. In this initialize the Container class, that is responsible for managing service bindings and resolutions.

- bind(): Registers a service with the container.
- resolve(): Retrieves a service from the container.

```php
class Container {
    protected $bindings = [];

    public function bind($key, $resolver) {
        $this->bindings[$key] = $resolver;
    }

    public function resolve($key) {
        if (!array_key_exists($key, $this->bindings)) {
            throw new Exception("No matching binding found for {$key}");
        }
        $resolver = $this->bindings[$key];
        return call_user_func($resolver);
    }
}
```

## App Class

The App class acts as a interface for the Container, providing a convenient interface for accessing services.

- setContainer(): Sets the container instance for the App.
- container(): Retrieves the container instance.
- bind(): Registers a service with the container.
- resolve(): Retrieves a service from the container.

```php
class App {
    protected static $container;

    public static function setContainer($container) {
        static::$container = $container;
    }

    public static function container() {
        return static::$container;
    }

    public static function bind($key, $resolver) {
        static::container()->bind($key, $resolver);
    }

    public static function resolve($key) {
        return static::container()->resolve($key);
    }
}
```

## Bootstrap

Bootstrap is a point of an application, where everything is set up and initialized. 

```php
$container = new Container();
$container->bind('Core\Database', function () {
    $config = require base_path('config.php');
    return new Database($config['database']);
});
App::setContainer($container);
```

In this , the bootstrap process:


1. Creates a new Container instance ($container)
2. Registers services with the container using the `bind` method (e.g., Core\Database)
3. Sets the container for the App using `App::setContainer($container)`


## Controller

Services can be resolved from the container in controllers using the `App::resolve()` method.

```php
$db = App::resolve('Core\Database');
```
Now a service container is properly built and you can see the project is working well.

I hope that you have clearly understood it.

Browser refresh on click of Home button using href
Tags: fullstack, angular, angulartestcases, routing
Published: 2024-07-02 11:57:04

I have a question on writing angular testcases on browser refresh.
Angular is a single page application .there is no browser refresh after logging in. I am building a website with angular in the frontend but not entirely. You will see what i mean in the below example scenario

When I am in Contacts page of the application ,and I click on the logo ,it should navigate me to the homepage always.
I could have simply gone with router link, but there is a catch.
See when Iam in contacts page of the application, the contacts tab is selected in the left-nav-item. When i click on the logo to navigate to the home button, the selection should not be there anymore. means it should work like a browser refresh. For that ,Iam using href instead of router link

 <div class="appName-container">
    <span class="appName"><a href="home-page">Logo</a></span>
 </div>

This will reload the page. See, what i mean when i said not fully angular .

Now my issue is with the testcases.I cant write element.click()

 it("should navigate to home page on click of logo",() => {
    const element = fixture.nativeElement.querySelector(".appName a") as HTMLElement;   
    spyOn(window.location, 'reload'); 
    element.click();
    expect(window.location.reload).toHaveBeenCalled();
  });

here element.click() will reload the page and so the test cases also stop to return Not Found.

I need to trigger the click() here to check if the browser is refreshed.Any suggestion on how to achieve it?

Smart contracts are a revolutionary technology that is changing our understanding of finance and asset management. In this emerging field, BitPower, as a pioneer, has demonstrated the great potential of smart contracts.

BitPower's smart contract technology makes the entire financial ecosystem more transparent, efficient and secure. The cumbersome procedures and human intervention in the traditional financial system are simplified and automated here. With its precise algorithms and tamper-proof characteristics, smart contracts ensure that every transaction is carried out within the rules and cannot be changed or deleted.

In the world of BitPower, smart contracts are at the core of all operations. They not only manage the flow of funds, but also automatically execute predetermined rules and conditions. This means that whether it is lending, investment or dividends, everything is determined by smart contracts, eliminating the risk of human operation. Users only need to deposit assets into BitPower's smart contracts, and the system will automatically complete the corresponding operations according to market conditions and preset rules.

For example, in BitPower's lending system, smart contracts are responsible for matching borrowers and lenders. When users deposit assets as collateral, smart contracts will instantly evaluate their value and calculate the corresponding loan amount and interest rate based on market conditions. This process is fully automated and transparent, and users can check their lending and returns at any time.

Smart contracts also bring inclusiveness to global financial services. No matter where you are, as long as you have an Internet connection, you can participate in the BitPower ecosystem. This decentralized design eliminates the geographical and identity restrictions in the traditional financial system, allowing more people to have the opportunity to enjoy financial services.

BitPower's smart contracts are not limited to financial transactions, but also extend to incentive mechanisms and community building. Users can get corresponding rewards by participating in the promotion and development of the platform. These reward mechanisms are also automatically executed by smart contracts to ensure fairness and transparency.

In general, the application of smart contracts in BitPower not only improves efficiency and security, but also breaks down the barriers of traditional finance and creates a more open and fair financial environment. Through smart contracts, BitPower not only simplifies complex financial operations, but also provides a trustworthy platform for global users, allowing everyone to participate and benefit fairly.

In this new world full of potential, BitPower is gradually realizing its vision through smart contract technology: building a decentralized, transparent and fair global financial ecosystem. This is not just a technological innovation, but also a new definition of the future of finance.

Published: 2024-07-02 11:49:42

IL (Intermediate Language) .NET’dagi oraliq til boʻlib, MSIL (Microsoft Intermediate Language) yoki CIL (Common Intermediate Language) nomi bilan ham tanilgan. C# yoki VB.NET kabi tillardagi manba kodi to'g'ridan-to'g'ri mashina kodiga emas, balki birinchi navbatda ILga kompilyatsiya qilinadi va bu uni platformadan mustaqil qiladi.

Arxitektura mustaqilligi: IL kodi CLR (Common Language Runtime) ning tegishli versiyasi o'rnatilgan har qanday platformada ishlashi mumkin. Bu ishlab chiquvchilarga kodni bir marta yozish va uni turli xil operatsion tizimlar va protsessor arxitekturalarida ishga tushirish imkonini beradi.

JIT kompilyatsiyasi: Dastur ishga tushirilganda, IL JIT kompilyatori (Just-In-Time kompilyatori) yordamida mashina kodiga aylantiriladi. Ushbu jarayon maqsadli platformada optimal ishlashni ta'minlash uchun ish vaqtida sodir bo'ladi.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/8em60bitdutx73yffj3h.jpg)

Turning xavfsizligi va modulliligi: IL CLR tomonidan turdagi xavfsizligini tekshirish va kod yaxlitligini ta'minlash uchun ishlatiladigan metama'lumotlarni o'z ichiga oladi. Modullashtirishni qo'llab-quvvatlash ilovani ish vaqtida birga yig'iladigan alohida komponentlarga bo'lish imkonini beradi.

Tilning mosligi: Barcha .NET tillari IL-ga kompilyatsiya qilinganligi sababli ular bir-biri bilan osongina o'zaro ishlashi mumkin. Bu shuni anglatadiki, siz bir xil dasturning turli qismlarini moslik muammosisiz ishlab chiqish uchun turli dasturlash tillaridan foydalanishingiz mumkin.

IL kodning koʻchishi va xavfsizligini taʼminlaydi, turli .NET tillari oʻrtasida oʻzaro ishlashni soddalashtiradi va ishlab chiquvchilarga koʻp qirrali va xavfsiz ilovalar yozish imkonini beradi.

Reset or change auto increment in postgres using `ALTER SEQUENCE` command. To use that command you can determine which table and column that you wil change.

For example you have roles table and inside that role table you want reset the id column.

You can use this simple query below to reset auto increment in postgres.

`ALTER SEQUENCE roles_id_seq RESTART WITH 1`

note:

the `_seq` is required, you cannot remove it. So the pattern is `{table}_{column}_seq`.

In postgres you cannot change to 0, the minimum value is 1.

How I created a unique PPT for "Load Testing" KT!
Tags: loadtesting, ppt, presentation, creative
Published: 2024-07-02 10:53:04

We all love to create great, eye catching PPTs don't we? So, there was a scenario during last year where we needed to share knowledge within the team on what we know and could add value to the team. 

I am being good at drawing thought, "Let me put my artist skills (whatever level it is) to good use". I was to present a PPT on "Load Testing" to let the team and juniors understand why it is needed. With the topic and content now ready, I had to select/create a PPT template to present. I thought let me create a theme where it will be unique and keep audience attentive. 

I decided to create a theme of colony of ants for load testing. Each slide being able to explain with illustrations of ants representing the content of the slide. 

**Tools** : Microsoft Powerpoint, XP Pen Deco Mini7 for drawing.

Here is how it turned out.

With these slides, I was able to keep audience engaged and attentive rather than using plain old readily available templates on PowerPoint.

Hope this inspires somebody to create such more unique creative illustrations.
