🚀 Bitcoin Updates All-Time High In Momentum Amid Its Scarcity 📈
Published: 2024-03-12 22:31:14

🚀 Bitcoin's recent surge to $73,000, followed by a retracement, is indeed closely tied to its scarcity. The decreased amount of Bitcoin available for purchase on centralized exchanges has played a significant role in this scarcity. According to reports from AMBCrypto and CryptoQuant, nearly 50,000 Bitcoins were withdrawn from exchanges throughout February, leading to a sharp drop in the cryptocurrency's available supply for purchase.
🐋 Another factor contributing to Bitcoin's scarcity is the increasing number of institutional investors, often referred to as whales in the crypto market. Glassnode data shows a 4% increase in the number of unique entities holding at least 1,000 Bitcoins in February, indicating a growing presence of institutional investors in the market.
💼 Additionally, the launch of Bitcoin spot ETFs has attracted traditional finance investors into the cryptocurrency market, further reducing the available supply of Bitcoin. The psychological impact of ETFs has fueled bullish forecasts and optimism surrounding mass crypto adoption.
Regarding WhiteBIT and NEAR Protocol, while they're significant in the cryptocurrency space, they may not directly impact Bitcoin's scarcity. However, WhiteBIT's integration with NEAR Protocol showcases the growing trend of interoperability and cross-chain functionality within the blockchain ecosystem. This integration allows for the mining of NEAR's HOT token and the withdrawal of USDT and USDC for free, impacting the performance of these currencies and potentially influencing market dynamics.
Despite these developments, scarcity remains a crucial metric for Bitcoin, especially amid halving events. A decrease in exchange supply suggests reduced selling pressure and a potential shift towards long-term holding, which is typically considered bullish for the cryptocurrency. As Bitcoin continues to see increased institutional adoption and investor interest, its scarcity becomes even more pronounced, driving its price higher in the long term. 📈💰

Demystifying APIs with Postman(beginner)
Tags: api, beginners, learning
Published: 2024-03-12 21:02:25

 

 

## INTRODUCTION TO APIs
You ever wondered how apps like weather forecasts or social media feeds access real-time information? Well, The secret  lies in APIs (Application Programming Interfaces).

APIs are basically **contract that allows code to talk to code**
they allow for sharing of resources and services across applications

**what are APIs?**
lets take an example of a restraunt.in a restaurant there is a waiter the customer and the kitchen.in order for the customer to order for example coffee he/she has to call the waiter and the waiter takes the information to the kitchen.in this scenario the customer(client)this can be browser, web app, etc. waiter(API)simplified interface interacting with backend ,kitchen(server)where backend processing happens.
APIs work similarly, enabling applications to "order" data from servers in a structured way.

**Why are APIs important?**

- help developers integrate exciting features and build automation example: using weather API instead of launching weather baloons

- allow enterprises to open up their product for faster innovation.

**types of API**

1. hardware API-this is simply interface for software to talk with hardware  a good example is phone camera talks to the operating system

2. software library APIs-interface for directly consuming code from another codebase example is using methods from a library you import into your application.

3. Web APIs-interface for communicating across code bases over a network. example  is fetching current stock prices from a finance API over the internet.

**How do you build APIs?**

- REST(representational state transfer)-this is what we will be using

- Graph QL

- Web sockets

- Web hook


**why use postman?**
postman is a user friendly platform that empowers beginners to.

- send API requests using(GET,POST,PUT,DELETE)

- Inspect responses

- organize requests

- test and debug

**Conclusion**
By understanding postman ,you will unlock doors to a vast world of APIs empowering you to build applications that interact with online services

Day 1 of #100daysofcode
Published: 2024-03-12 20:48:09

Well, exciting moment! It always feels great to start a new project and this is the first day. A lot to learn along the way.

These are the main tasks I completed for today: 

I chose React with Vite for this project. 

Even though I have been using GitHub for a while, I have never started a working a repository from scratch right away and building it from there. That is because I have always contributed to other people's projects or because I uploaded the project when it was pretty much done. 

So I spent the majority of my time learning a bit more about GitHub before uploading my repository. I learned that it is a good practice to include the 'node_modules' folder in the .gitignore file. 

There case few exceptional cases in which you may want to do that, however, uploading that folder has many downsizes because they can significantly bloat your repository size and slow down operations like cloning and pushing.

Then, I spent the rest of the time mainly deleting prebuilt Vite files, organizing a bit better the project's structure, adding some  boilerplate and choosing some basic styles.

Hello community!

Ever since Claude 3 released, I've been using Opus to code really fast.

Copying and pasting multiple files into the context window was the only bottleneck, so I built a handy tool that automatically converts files/folders into a format optimized for Claude, then copies them to your clipboard.

I've always wanted to build a CLI tool, and when I realized that you can build one using React with [Ink](https://github.com/vadimdemedes/ink), I converted my Python script into a CLI tool.

The project is fully open-source under the MIT license, contributors are more than welcome!

how to convert a String to an Integer in Rust
Published: 2024-03-12 20:46:49

Converting a string to an integer is a common operation in programming, and Rust provides robust methods to accomplish this task. Let's explore how to convert a `String` to an integer step by step.

### 1. Parsing with `parse()`

Rust's standard library offers the `parse()` method for parsing strings into integers. This method works for various integer types such as `i32`, `u64`, etc.

```rust
fn main() {
    let my_string = "123";
    let my_integer: i32 = my_string.parse().expect("Failed to parse string to integer");
    println!("Converted integer: {}", my_integer);
}
```

In this example, `parse()` attempts to parse the string into the specified integer type (`i32`). If successful, it returns a `Result` containing the parsed integer. We use `expect()` to handle any parsing errors.

### 2. Handling Errors

Since parsing can fail if the string doesn't represent a valid integer, it's crucial to handle potential errors gracefully.

```rust
fn main() {
    let my_string = "abc";
    let my_integer: Result<i32, _> = my_string.parse();
    match my_integer {
        Ok(number) => println!("Converted integer: {}", number),
        Err(_) => println!("Failed to parse string to integer"),
    }
}
```

Here, we use pattern matching to differentiate between successful parsing (`Ok`) and parsing errors (`Err`). 

### 3. Using `unwrap()` for Simplicity

If you're confident the string will always contain a valid integer, you can use `unwrap()` for a more concise syntax.

```rust
fn main() {
    let my_string = "456";
    let my_integer = my_string.parse().unwrap();
    println!("Converted integer: {}", my_integer);
}
```

However, be cautious when using `unwrap()`, as it will panic if parsing fails, causing your program to crash.

### 4. Handling Different Integer Types

You can parse strings into various integer types by specifying the desired type explicitly.

```rust
fn main() {
    let my_string = "789";
    let my_integer: u64 = my_string.parse().unwrap();
    println!("Converted integer: {}", my_integer);
}
```

In this example, we parse the string into a `u64` (unsigned 64-bit integer).

### Conclusion

Converting a string to an integer in Rust is straightforward using the `parse()` method. Remember to handle potential parsing errors appropriately to ensure the robustness of your code. Whether you need a signed or unsigned integer, Rust provides flexibility in specifying the desired integer type. 

Happy parsing!
What are the differences between Rust's `String` and `str`?
Tags: rust, programming, string, webdev
Published: 2024-03-12 20:33:56

When diving into Rust programming, understanding the distinctions between `String` and `str` is crucial. Despite their apparent similarity, they serve different purposes and have different characteristics. Let's unravel these differences step by step.

### 1. What is `str`?

In Rust, `str` is an immutable sequence of UTF-8 bytes stored in memory. It represents a string slice, which means it's a view into a string, rather than the string itself. Since `str` is immutable, you cannot modify the contents of a string slice.

```rust
let my_str: &str = "Hello, World!";
```

### 2. What is `String`?

On the other hand, `String` is a growable, mutable, owned UTF-8 encoded string. It can be dynamically modified and resized as needed, making it more versatile than `str`.

```rust
let my_string: String = String::from("Hello, World!");
```

### 3. Ownership and Memory Allocation

One of the key differences between `String` and `str` lies in how they handle memory allocation and ownership.

- **`String`:** Owned type. It owns the memory it occupies on the heap. You can freely modify, append, or delete characters from a `String`, and it will automatically manage the memory for you.

- **`str`:** Borrowed type. It's often used as a reference to a portion of memory owned by another data structure, like `String` or a string literal. It doesn't own the memory itself, but rather borrows it from another source. 

### 4. Mutability

- **`String`:** Mutable. You can modify the contents of a `String` after it's been created. For example, you can append characters, remove characters, or change specific characters within the string.

- **`str`:** Immutable. Once a string slice is created, you cannot change its contents. Attempting to modify a `str` directly will result in a compilation error.

### 5. Performance Considerations

Since `String` owns its data and can modify it, it may involve more overhead in terms of memory allocation and deallocation compared to `str`. If you're working with a fixed, unchanging string, using `str` can be more memory-efficient.

### Conclusion

In summary, understanding the differences between `String` and `str` in Rust is essential for writing efficient and safe code. Remember:

- `String` is a mutable, growable, and owned string type.
- `str` is an immutable string slice type that borrows from another data structure.
- Consider ownership, mutability, and performance implications when choosing between them in your Rust code.

By grasping these distinctions, you'll be better equipped to leverage Rust's powerful string handling capabilities effectively. 

Happy coding!
image/video/gifs not loading in Qt/QML
Tags: qml, qt
Published: 2024-03-12 20:31:58

If you've ever been baffled by why your resources aren't loading after running your QTQuick project, you're not alone. But fear not, the solution might be simpler than you think!

**The Problem:**
When you start a QTQuick project, sometimes the necessary moc (Meta-Object Compiler) libraries aren't added in the cmake configuration. This oversight can prevent your resources from loading properly, leaving you scratching your head in confusion.

**The Solution:**
Luckily, there's a straightforward fix. By adding a couple of lines to your cmake configuration file (CMakeLists.txt), you can ensure that the moc libraries are included, allowing your resources to load correctly.

Here's what you need to add to your CMakeLists.txt file:

```
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
```
These lines instruct CMake to automatically handle the generation of moc files (which are used for signals and slots in Qt) and to process the resource files.

**Putting It All Together:**
To integrate these changes into your project, simply insert the lines into your CMakeLists.txt file, typically near the beginning:
```
..
project(yourAppName VERSION 0.1 LANGUAGES CXX)

set(CMAKE_AUTOMOC ON)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)

find_package(Qt6 6.2 COMPONENTS Quick REQUIRED)
..
```
By doing so, you're ensuring that the necessary moc libraries are included in the build process, resolving the issue of your resources not loading.

With this tweak, your QTQuick project should now run smoothly, saving you from further frustration and helping you focus on what really matters: building your awesome application. You're welcome!
How to convert an array into an object in javascript
Tags: webdev, javascript, beginners, programming
Published: 2024-03-12 20:27:56


To convert an array into an object we will create a function and give it 2 properties, an array and a key.
const convertArrayToObject = (array, key) => {};
We will then reduce the array, and create a unique property for each item based on the key we have passed in.

We also need to remember to set an initial Value, and also pass in the current value (...obj in the below).
const convertArrayToObject = (array, key) => {
  const initialValue = {};
  return array.reduce((obj, item) => {
    return {
      ...obj,
      [item[key]]: item,
    };
  }, initialValue);
};
So now if we log out our function (passing in the array and our key which is a unique identifier in this case the id property) we will see our array is now an object.
console.log(
  convertArrayToObject(
    [
      { id: 111, name: 'John', age: 29 },
      { id: 112, name: 'Sarah', age: 25 },
      { id: 122, name: 'Kate', age: 22 },
      { id: 123, name: 'Tom', age: 21 },
      { id: 125, name: 'Emma', age: 24 },
    ],
    'id',
  ),
);
returns
{
  111:{ id: 111, name: 'John', age: 29 },
  112:{ id: 112, name: 'Sarah', age: 25 },
  122:{ id: 122, name: 'Kate', age: 22 },
  123:{ id: 123, name: 'Tom', age: 21 },
  125:{ id: 125, name: 'Emma', age: 24 }
}
We can now easily look up data in our array by an id and use it as required.
Developer diary #6. Who is main?
Tags: programming, android, management, agile
Published: 2024-03-12 20:24:00

Sometimes, I find myself in situations where projects start from scratch. Several people have joined the team. We don't have the role of a leader, and we try to solve problems through communication. In general, at this time, the project has a lot of important problems that should be solved in the short term. How will work be organized? What scope of tasks will be included in MVP? Who will create tasks? How track time? Etc. 

Very often, we have a person who has more experience or more often communicates with the customer to clarify technical requirements. All think that this person should play the role of leader and should organize the whole process of development, but he is an engineer and he isn't a project manager. He has another mindset.  

How the result, starting of project looks like chaos.
