To build a fully-fledged website and scraper for the Roblox Friends API in Rust, you can create a web application that allows users to check if a given user is friends with another user (for example, David Baszucki). Below is a sample Rust application that uses Actix-web as the web framework and leverages the Roblox API to check friendship status.

**Step 1: Set Up the Project**

First, ensure you have Rust installed. If not, you can download it from [https://www.rust-lang.org/tools/install](https://www.rust-lang.org/tools/install).

Create a new Rust project:

```bash
cargo new roblox_friendship_checker
cd roblox_friendship_checker
```

**Step 2: Update `Cargo.toml` Dependencies**

Add the following dependencies to your `Cargo.toml` file:

```toml
[dependencies]
actix-web = "4"
serde = { version = "1.0", features = ["derive"] }
serde_json = "1.0"
reqwest = { version = "0.11", features = ["json", "gzip"] }
```

**Step 3: Implement the Application**

Replace the contents of `src/main.rs` with the following code:

```rust

**Explanation:**

- **Dependencies:**
  - `actix-web`: Used for the web server framework.
  - `serde` and `serde_json`: For JSON serialization/deserialization.
  - `reqwest`: For making HTTP requests to the Roblox API.

- **Index Route (`/`):**
  - Displays an HTML form where users can enter a User ID or Username and check if they are friends with the target user.

- **Check Friendship Handler (`/check_friendship`):**
  - Retrieves the form data.
  - Uses the `resolve_user_id` function to convert usernames to User IDs.
  - Calls `are_friends` to check if the two users are friends.
  - Returns the result in an HTML response.

- **Resolving Usernames to User IDs:**
  - If the input is not a number, the code assumes it's a username.
  - It sends a GET request to `https://api.roblox.com/users/get-by-username` to resolve the username to a User ID.

- **Checking Friendship Status:**
  - Fetches the friends list of the user using `https://api.roblox.com/users/{userId}/friends`.
  - Iterates through the friends list to see if the target user is a friend.

**Note:**

- The `api.roblox.com` endpoints used in this code are accessible without authentication and can be used to retrieve public information.
- The public APIs may have limitations or may be deprecated in the future. Always check the latest Roblox API documentation and terms of service to ensure compliance.

**Step 4: Run the Application**

Build and run the application:

```bash
cargo run
```

You should see output similar to:

```
Listening on http://127.0.0.1:8080
```

Open your web browser and navigate to `http://127.0.0.1:8080`.

**Step 5: Use the Website**

- **Check Friendship with David Baszucki:**
  - **David Baszucki's User ID:** `1`
  - **David Baszucki's Username:** `Builderman`

Enter a User ID or Username in the first field and `1` or `Builderman` in the second field. Click "Check Friendship" to see if they are friends.

**Example:**

- **Input:**

  ```
  User ID or Username: SomeUser123
  Target User ID or Username: Builderman
  ```

- **Output:**

  ```
  User SomeUser123 is NOT friends with user Builderman.
  ```

**Additional Features:**

You can extend this application by:

- **Adding Styling:** Use CSS to improve the visual appearance.
- **Error Handling:** Provide more detailed error messages.
- **Caching Results:** Implement caching to reduce API calls for frequently checked users.
- **Asynchronous Requests:** Allow users to check multiple friendships simultaneously.

**Disclaimer:**

- Ensure that your application complies with Roblox's API usage policies and terms of service.
- Be mindful of rate limits and avoid overloading the API with excessive requests.
- This application uses public endpoints that may change or be deprecated. Always refer to the official Roblox API documentation for updates.

**Conclusion:**

You've now created a Rust-based web application that checks the friendship status between two Roblox users using the Friends API. This serves as a foundation for building more advanced tools and applications interacting with Roblox's platform.

Feel free to customize and expand upon this code to suit your specific needs!

Tell me about Roblox in an angry tone

Roblox, honestly! It's absolutely maddening how that platform operates. It's packed with games that are often glitchy and poorly made, making for a frustrating experience. And the relentless push for in-game purchases is just over the top! It's infuriating that they seem more focused on squeezing money out of players than providing a quality gaming environment. The interface is a chaotic mess, and updates rarely fix the actual problems. It's exasperating to see so much potential wasted because they can't get the basics right!

从地球发射一个火箭绕太阳一圈再返回地球请列出运动方程

要描述从地球发射一个火箭绕太阳一圈再返回地球的运动过程，首先需要建立一个参考系并定义相关参数。通常选择太阳为原点的惯性参考系。为了简单化，可以假设火箭的运动是仅受太阳和地球的引力影响的两体或三体问题。

### 1. 定义参数
- \( m \) - 火箭的质量
- \( M_s \) - 太阳的质量
- \( M_e \) - 地球的质量
- \( G \) - 引力常数
- \( r \) - 火箭与太阳的距离
- \( r_e \) - 火箭与地球的距离
- \( v \) - 火箭的速度
- \( \mathbf{r} \) - 火箭相对于太阳的位置矢量

### 2. 运动方程
在一个两体问题（火箭和太阳）的近似下，火箭受太阳的万有引力作用，可以通过以下微分方程来描述：

\[ \frac{d^2\mathbf{r}}{dt^2} = -\frac{GM_s}{r^3} \mathbf{r} \]

### 3. 初始条件
- 初速度 \( v_0 \) 应该足够大以克服地球重力并进入绕太阳的轨道。
- 发射角度和速度方向取决于期望的轨道（如霍曼转移轨道）。

### 4. 轨道类型
如果希望实现最小能量轨道（如霍曼转移轨道），可以使用能量方程计算所需初速度：

\[ v_0 = \sqrt{G \left( \frac{2M_s}{r_1} - \frac{1}{a} \right)} \]

其中 \( r_1 \) 为初始半径（即地球到太阳的距离），\( a \) 为轨道半长轴。

### 5. 地球影响
如果考虑地球影响，则需要将火箭、地球、太阳视为三体问题，使用三个体力学来模拟，此时：

\[ \frac{d^2\mathbf{r}}{dt^2} = -\frac{GM_s}{r^3} \mathbf{r} - \frac{GM_e}{r_e^3} (\mathbf{r} - \mathbf{r}_e) \]

在以上方程中，\( \mathbf{r}_e \) 表示地球中心到太阳的距离矢量。

### 6. 返回地球
在轨道计算中使用一些数值方法来调整轨迹以确保火箭能在一个轨道周期后接近并返回地球，这通常需要调整初始条件（例如速度和角度）。

### 结论
上述步骤是一个简化模型，实际中应考虑复杂因素如太阳系其他天体的引力扰动、非球对称质量分布、火箭的推进能力等。完整的任务需要通过数值方法模拟具体的轨迹。

Может ли просто физлицо дать в долг другому простому физлицу?

Да, физическое лицо может предоставить заем другому физическому лицу. Это вполне легальная и распространенная практика. Однако, чтобы минимизировать риски и избежать возможных недоразумений, рекомендуется составить письменный договор займа, в котором будут четко прописаны условия займа: сумма, сроки возврата, процентная ставка (если таковая имеется) и другие важные детали.

Договор займа может быть составлен в простой письменной форме, и обычно не требует нотариального заверения. Однако, если сумма займа значительная, может быть целесообразно оформить такой договор у нотариуса для дополнительной надежности.

Также стоит учитывать, что в некоторых странах при предоставлении займа может возникнуть обязательство по уплате налогов на доходы, полученные от процентов. Поэтому важно знать соответствующее законодательство вашей страны.

В любом случае, обе стороны — заемщик и заимодавец — должны хорошо понимать все условия сделки и доверять друг другу, чтобы избежать возможных конфликтов в будущем.
