> Lightning cracks, thick rain drops fall down relentlessly, making it almost impossible to see outside. The wind howls around the bridge, rolling the ship in the giant waves. We’re being hunted.

## Building in Public

It’s a game we’ve dreamed about for years now. We never started development, but that changes today. At this stage, it’s not much more than a few loosely related thoughts, ideas and experiments we want to run. There is a million things to learn, such as [Golang](https://go.dev/), [Ebitenengine](https://ebitengine.org/), game design, sound design, music, graphics, [aseprite](https://www.aseprite.org/), entity component system, artificial intelligence.

This blog will be used to document our journey, the things we learn along the way, and the progress the game is making. We’ll be building in public, to keep us on our toes.

## The Game

In the game the player will pilot a destroy-class ship, with a unique, challenging control-scheme. Fights will take place in the air and with submerged enemies. You can expect updates as we refine our thinking around the game, its design and gameplay loop.

## The Latest

We publish every build at the following url, fully playable in your browser thanks to WASM !

Server-Side Rendering (SSR) with React 18
Tags: react, ssr, javascript
Published: 2024-01-27 08:20:15

First, let's create the server code:

```js
// server.js
import express from 'express';
import { pipeToNodeWritable } from 'react-server-dom-webpack/writer';
import path from 'path';
import fs from 'fs';
import React from 'react';
import { renderToPipeableStream } from 'react-dom/server';
import App from './src/App';

const app = express();

app.use(express.static('dist'));

app.get('/', (req, res) => {
  const manifest = fs.readFileSync(path.resolve(process.cwd(), 'dist/react-client-manifest.json'), 'utf8');
  const moduleMap = JSON.parse(manifest);

  const stream = renderToPipeableStream(<App />, { moduleMap });

  res.setHeader('Content-Type', 'text/html');
  pipeToNodeWritable(stream, res, {
    onCompleteShell() {
      res.end();
    },
  });
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
```

Next, let's create the client code:

```js
// client.js
import React from 'react';
import ReactDOM from 'react-dom';
import { createFromReadableStream } from 'react-server-dom-webpack';

const root = ReactDOM.createRoot(document.getElementById('root'));

fetch('/react').then(response => {
  const stream = createFromReadableStream(response.body);
  React.startTransition(() => {
    root.render(<React.Suspense fallback="Loading...">{stream}</React.Suspense>);
  });
});
```

The server uses Express to serve a React app. When a request is made to the root URL ("/"), the server renders the app to a stream and sends it to the client.

The client then fetches the stream from the server and renders it to the DOM. The React.Suspense component is used to show a loading message while the app is being fetched.

Please note that this is a basic example and doesn't include things like error handling or data fetching.

Are React Hooks just normal javascript functions?
Tags: react, javascript, webdev, functionalreactiveprogramming
Published: 2024-01-27 08:17:53

The answer is no, sort of. 


React Hook is a special function in React, introduced in React 16.8 to enable state and other React features in functional components without writing a class.


## How are they different than a normal javascript function - 





### Purpose 

Hooks are specific to React and are used to hook into React features like state management, lifecycle methods, context, etc., in functional components. They allow you to use state and other React features without writing a class.



Regular functions in JavaScript are general-purpose and are used for a wide range of programming tasks. They don't have any specific connection to React.




### React Lifecycle Integration


Hooks like useEffect are designed to tap into React's lifecycle events.

```
function DataFetcher() {
    const [data, setData] = useState(null);

    // Equivalent to componentDidMount and componentDidUpdate
    useEffect(() => {
        const fetchData = async () => {
            const response = await fetch('https://api.example.com/data');
            const result = await response.json();
            setData(result);
        };

        fetchData();

        // Equivalent to componentWillUnmount
        return () => {
            // Cleanup logic goes here (e.g., aborting a fetch request)
            console.log('Component will unmount and cleanup');
        };
    }, []); // The empty array makes this effect run only on mount and unmount
}
```


useEffect Hook: Manages the lifecycle events similar to componentDidMount and componentWillUnmount. The empty dependency array [] tells React to run the effect only once after the initial render (like componentDidMount) and on unmount (like componentWillUnmount).The return function in useEffect is a cleanup function that executes when the component is about to unmount, which is similar to componentWillUnmount in class components. 



### Stateful and Reactive 


Hooks like useState are stateful. They maintain state across renders and react to state changes, triggering component re-renders.


### Restrictions on Use

Hooks come with rules, Hooks can only be called at the top level of React functional components or custom Hooks. They cannot be called conditionally, in loops, or nested functions. Normal functions don’t have these restrictions.



In summary, while React Hooks are specialized functions designed to work within the React ecosystem, particularly for state management and lifecycle integration in functional components, unlike normal JavaScript functions which are more versatile.
what makes software development challenging
Published: 2024-01-27 08:11:51


Complexity: Modern software systems can be incredibly complex, involving numerous components, interactions, and dependencies. 

Managing this complexity requires careful design, architecture, and implementation.

Changing Requirements: Requirements for software projects often evolve over time, leading to the need for adaptation and flexibility. 

Managing changing requirements while keeping the project on track can be a significant challenge.

Technical Constraints: Developers must work within technical constraints such as performance requirements, compatibility with existing systems, 

security considerations, and scalability. Balancing these constraints while delivering functionality can be difficult.

Team Collaboration: Software development often involves collaboration among team members with diverse skills, backgrounds, and perspectives. 

Effective communication and coordination are essential for successful teamwork, but they can be challenging to achieve, particularly in distributed or remote teams.

Time and Resource Constraints: Projects are typically subject to time and resource limitations, requiring developers to prioritize tasks, make trade-offs, 

and deliver results within tight deadlines. Managing time and resources effectively is crucial for project success.

Testing and Quality Assurance: Ensuring the quality and reliability of software requires thorough testing and quality assurance processes.

 Identifying and fixing bugs, optimizing performance, and ensuring compatibility across different platforms can be time-consuming and challenging.

Technology Stack: The choice of technology stack (programming languages, frameworks, tools, etc.) can have a significant impact on the development process. 

Keeping up with new technologies, evaluating their suitability for the project, and learning how to use them effectively can be daunting.

User Experience: Building software that provides a positive user experience requires understanding user needs, preferences, and behaviors. 

Designing intuitive interfaces, optimizing performance, and addressing usability issues are all part of creating a compelling user experience.

Security: Protecting software from security threats such as hacking, data breaches, and malware is essential. Incorporating security best practices, 

performing regular security audits, and staying informed about emerging threats are critical for safeguarding software systems.

Maintenance: Software development doesn't end when a product is released; it requires ongoing maintenance, updates, and improvements.

 Managing the evolution of software over time, addressing user feedback, and staying ahead of competitors are ongoing challenges for developers.

Virtual Method in C#
Tags: csharp
Published: 2024-01-27 07:26:44

C# Virtual Method in C# with Code

In C#, a virtual method is a method that can be overridden in a derived class. It allows for runtime polymorphism, which means that the appropriate method implementation will be determined at runtime based on the actual type of the object.

To declare a virtual method in C#, you need to use the `virtual` keyword in the method signature. Here's an example:

```c#
public class Shape
{
    public virtual void Draw()
    {
        Console.WriteLine("Drawing a shape");
    }
}

public class Circle : Shape
{
    public override void Draw()
    {
        Console.WriteLine("Drawing a circle");
    }
}

public class Rectangle : Shape
{
    public override void Draw()
    {
        Console.WriteLine("Drawing a rectangle");
    }
}

public class Program
{
    public static void Main()
    {
        Shape shape = new Circle();
        shape.Draw(); // Output: Drawing a circle

        shape = new Rectangle();
        shape.Draw(); // Output: Drawing a rectangle
    }
}
```

In the above code, we have a base class called `Shape` with a virtual method `Draw()`. We also have two derived classes `Circle` and `Rectangle` that inherit from the `Shape` class and override the `Draw()` method with their own implementations.

In the `Main()` method of the `Program` class, we create an instance of the `Circle` class and assign it to the base class reference variable `shape`. When we call the `Draw()` method on the `shape` object, it executes the overridden `Draw()` method in the `Circle` class, which outputs "Drawing a circle" to the console.

Similarly, we create an instance of the `Rectangle` class and assign it to the `shape` variable. When we call the `Draw()` method again, it executes the overridden `Draw()` method in the `Rectangle` class, which outputs "Drawing a rectangle" to the console.

The use of virtual methods in C# allows for flexibility in handling different types of objects through a common interface. It enables polymorphism and helps in achieving code reusability by providing an extensible design pattern.

The mysterious of Antimatter
Published: 2024-01-27 07:32:39

At the beginning of time, just moments after the Big Bang, numerous particles came into existence; at the same time, an almost equal number of antiparticles appeared. These subatomic exotics are nearly identical to their ordinary particle kin, but differ in some key ways. When matter and antimatter meet, the two annihilate one another, which means that the dawn of the universe included a spectacular microscopic fireworks display. 

Antimatter is sort of like a mirror to ordinary matter, having the same mass but an opposite charge. Neutrinos, which have no charge, are thought to be their own antiparticles, although experiments have yet to confirm this theory. Along with being created shortly after the Big Bang, antimatter can arise from a wide variety of nuclear processes, and can exist for a short time in any of the particle accelerators worldwide. 

A persistent mystery
In 2018, scientists were even more perplexed when they made the most precise measurement of antimatter to date and found that antimatter and matter behave nearly identically. The finding suggests that particles and their opposites should have been created in equal numbers at the beginning of the universe; however, if true, the fact that matter prevails over antimatter is ever more difficult to reconcile.

Researchers are diligently seeking the factor that explains the dominance of matter over antimatter in our cosmos. Calculations suggest that just after the Big Bang, when particles and antiparticles annihilated one another, there was a slight imbalance in their numbers. Less than one in every billion ordinary particles survived the melee and went on to form all the matter around us today. But why? Scientists worldwide are working to determine if a neutrino acts as its own antiparticle, which would have allowed a small fraction of neutrinos to transition from antimatter to matter at the universe's inception. In this scenario, a slight matter imbalance would have existed back then. 

Antimatter has been created and sustained in small quantities in particle-physics laboratories. Some research teams have gone so far as to create antiprotons, and drive them around in a van so that physicists at CERN could transport them to a nearby facility.read more http://tinyurl.com/2ycm3e93

👨‍💻 Daily Code 51 | Color Flipper Button in 🟨 JavaScript
Tags: beginners, daily, javascript
Published: 2024-01-27 07:27:19

Today I  gave myself the exercise to create a button button that background color of a website to a random one

# My Code

I forgot to document step by step today, but here is the code that achieves my goal

```jsx
<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Exercise: Create a 'Color Flipper' Button</title>
</head>

<body>
    <button id="js-button">Color Flipper</button>

    <script>
        function getRandomColor() {
            const letters = '0123456789ABCDEF';
            let color = '#';
            for (let i = 0; i < 6; i++) {
                color += letters[Math.floor(Math.random() * 16)];
            }
            return color;
        }

        document.getElementById('js-button').onclick = function () {
            let randomColor = getRandomColor();
            document.body.style.backgroundColor = randomColor;
        }

    </script>
</body>

</html>
```

I got the `getRandomColor()` from ChatGPT. Interesting again how raw and mathy that works.

also again cool that `document.getElementById()` can just be replaced by `document.body` if that’s the object to be manipulated. No need to give the body an ID and get it that way etc.

Well that’s it again for today. Enjoy the weekend everyone 🥳
