Multiple ways to Clone or Copy a list in Python
Tags: python, beginners
Published: 2024-07-09 19:41:53

Python provide multiple ways to achieve the desired result. For example, to copy a list to another list there are different methods:

- Through List slicing operation 

**#Method 1**
lstcopy = lst[:]
print("Cloning By list slicing lst[:] ",lstcopy)


- Through copy() method

**#Method2**
lstcopy = lst.copy()
print("Cloning By list copying lst.copy() ",lstcopy)


- List Comprehension operation

**#Method3**
lstcopy = [i for i in lst]
print("Cloning By list Comprehension ",lstcopy)


- Through append() method

**#Method4**
lstcopy = []
for i in lst : 
lstcopy.append(i)
print("Cloning By list append ",lstcopy)

**_This diagram illustrates the key steps involved in the request flow:_**

1. DNS Resolution
: The browser performs a DNS lookup to resolve the hostname www.google.com to an IP address.
Firewall: The encrypted HTTPS request from the browser passes through the firewall.

2. Load Balancer: The load balancer receives the encrypted request and distributes it to an available web server.

3. Web Server: The web server forwards the request to the application server.

4. Application Server: The application server fetches data from the database as needed to generate the web page.

5. Database: The application server queries the database to retrieve the necessary data.

6. Web Page Generation: The application server generates the web page and returns it to the web server.

7. Response Flow: The web page is then passed back through the load balancer, firewall, and finally to the browser.

## 
This schema provides a high-level overview of the request flow, including the key components involved (DNS server, firewall, load balancer, web server, application server, and database) and the encryption of the traffic between the browser and the web server.
Software engineering principles cheat sheet
Tags: softwaredevelopment, javascript, beginners, webdev
Published: 2024-07-09 20:49:16

The software engineering principles cheat sheet I would give to myself If I was preparing for technical interviews again

**🟠 ACID Properties**
1. Atomicity: Transactions are all-or-nothing, fully completed, or not.
2. Consistency: Transactions ensure the database remains in a valid state.
3. Isolation: Transactions operate independently, unaffected by others.
4. Durability: Completed transactions are permanently recorded despite failures.

**🟠SOLID Principles**
1. Single Responsibility: Limit each class to a single responsibility.
2. Open/Closed: Classes should be open for extension but closed for modification.
3. Liskov Substitution: Subclasses should be substitutable for their base classes.
4. Interface Segregation: Prefer small, focused interfaces over broad ones.
5. Dependency Inversion: Rely on abstractions rather than concrete implementations.

**🟠Design Patterns:**
1. Factory Method: Create objects without specifying the exact class.
2. Abstract Factory: Create families of related objects without specifying their concrete classes.
3. Builder: Construct complex objects through a series of steps.
4. Prototype: Copy existing objects without knowing the specifics of their construction.
5. Singleton: Ensure a class has only one instance with a global point of access.
6. Adapter: Enable cooperation between incompatible interfaces.
7. Bridge: Decouple an abstraction from its implementation.
8. Composite: Organize objects into tree structures to represent part-whole hierarchies.
9. Decorator: Add responsibilities to objects dynamically.
10. Facade: Provide a simple interface to a complex system.
11. Flyweight: Reduce the cost of creating and managing many similar objects.
12. Proxy: Control access to another object, handling expensive or complex operations.
13. Command: Encapsulate a request as an object, allowing parameterization and queuing.

**🟠 System Design Principles**
1. Scalability: Design systems to handle growth in users and data smoothly.
2. Performance: Optimize response times and resource utilization.
3. Reliability: Ensure the system functions correctly and consistently.
4. Availability: Design for near-constant operability.
5. Security: Safeguard systems against unauthorized access and vulnerabilities.
6. Maintainability: Facilitate updates and maintenance with minimal disruption.
7. Modularity: Build components that can be updated independently.
8. Reusability: Design for components to be reused across different parts of the system.
9. Decomposability: Break down complex processes into simpler, manageable parts.
10. Concurrency: Design interactions to handle multiple operations simultaneously without conflict.
Practicing politeness in JavaScript code 🤬

Imagine that you published a big open source project and many people are currently changing your code or updating the project documents.

what if someone accidently write something race related , gender favoring , polarizing and etc... 👀


![cat typing](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ng0a48yz92wjd15esz2o.gif)

we have a tool called **alex** ! 

According to what is written in the [documentation ](https://github.com/get-alex/alex) of this tool:

> Whether your own or someone else’s writing, alex helps you find gender favoring, polarizing, race related, or other unequal phrasing in text.

## Set up Alex in our project

in order to use alex inside our project , first we need to install its package. 

it will be a good practice if you install alex as a dev-dependency 
or you can just install it globally in your system.

```bash
npm i -D alex 
```
Alex reads plain text, HTML, MDX, or markdown as input. 

One of its uses is to scan all project documents for any literary issues.

Let’s assume that all our documents are written in Markdown format, so we instruct Alex to check all files with a .md extension

In our package.json file, we can create a script like: 

```json
{
  "scripts": {
      "test-doc" : "npx alex *.md"
}
```
After that, I create a file called policy.md as an example document:

```md
## the boogeyman walked to class
```
if you run the **test-doc** command, you will probably get this result:

```bash
> test-doc
> npx alex *.md

policy.md
  1:8-1:17  warning  `boogeyman` may be insensitive, use `boogeymonster` instead  boogeyman-boogeywoman  retext-equality

‼ 1 warning
```
You can use this command together with tools such as **Husky ** and **lint-staged** to run the process of checking your files automatically. 🤖

What are your thoughts on this tool, and how crucial is compliance with this matter for software projects? 🧐🤗
Vector and Stack Classes
Tags: java, programming, learning, beginners
Published: 2024-07-09 21:33:03

**Vector** is a subclass of **AbstractList**, and **Stack** is a subclass of **Vector** in the Java API. The Java Collections Framework was introduced in Java 2. Several data structures were supported earlier, among them the **Vector** and **Stack** classes. These classes were redesigned to fit into the Java Collections Framework, but all their old-style methods are retained for
compatibility.

**Vector** is the same as **ArrayList**, except that it contains synchronized methods for accessing and modifying the vector. Synchronized methods can prevent data corruption when a vector is accessed and modified by two or more threads concurrently. For the many applications that do not require synchronization, using **ArrayList** is more efficient than using **Vector**.

The **Vector** class extends the **AbstractList** class. It also has the methods contained in the original **Vector** class defined prior to Java 2, as shown in Figure below.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/mbg3j8s9m64ym21a5psq.png)

Most of the methods in the **Vector** class listed in the UML diagram in Figure above are similar to the methods in the **List** interface. These methods were introduced before the Java Collections Framework. For example, **addElement(Object element)** is the same as the **add(Object element)** method, except that the **addElement** method is synchronized. Use the **ArrayList** class if you don’t need synchronization. It works much faster than **Vector**.

The **elements()** method returns an **Enumeration**. The **Enumeration** interface was introduced prior to Java 2 and was superseded by the **Iterator** interface. **Vector** is widely used in Java legacy code because it was the Java resizable array implementation before Java 2.

In the Java Collections Framework, **Stack** is implemented as an extension of **Vector**, as illustrated in Figure below.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/y5zh6lhjlxqukmhkve9m.png)

The **Stack** class was introduced prior to Java 2. The methods shown in Figure above were used before Java 2. The **empty()** method is the same as **isEmpty()**. The **peek()** method looks at the element at the top of the stack without removing it. The **pop()** method removes the top element from the stack and returns it. The **push(Object element)** method adds the specified element to the stack. The **search(Object element)** method checks whether the specified element is in the stack.
How to recover stolen USDT

How Founding a Startup is Curing my Perfectionism (1/3)
Tags: startup, mentalhealth, productivity
Published: 2024-07-09 21:45:30

From childhood, many of us learn to tie our self-worth to our performance. When achievements aren't acknowledged or appreciated appropriately, this mindset can affect our hobbies, projects, career paths, and even relationships throughout life. Launching a startup, (alongside proper therapy,) has been, - I dare to say - vital in healing my perfectionism and fear of failure (and success). Here’s how:

## 1. Launching an MVP - If it's 'perfect,' you're doing it wrong
One of the first challenges in launching a company is creating a Minimum Viable Product (MVP) that's so limited in functionality you might feel embarrassed to show it to anyone. The MVP should be the simplest solution that still addresses the customer's problem, and it needs to be released quickly.

For a perfectionist, this concept can be liberating: "So, the less I polish every detail, the better I am?" It's a counterintuitive notion that can be quite freeing. Here, the pressure of perfect performance is not just relieved but inverted: the more basic and minimal the solution, the better.

## 2. No one knows the best course of action. Only you.
Despite the abundance of advice available, no one can tell you the perfect path for your startup. This forces the perfectionist to realize that only they know what’s best for their business. They must trust their choices, make decisions independently, and be prepared to evaluate, correct, or even abandon those decisions as necessary. This process builds confidence and self-trust, essential for growth.

Making a choice and trusting it is crucial because indecision is the worst option.

## Conclusion
Starting a company puts you in a unique position where no one else knows the best path forward—only you do. This realization, combined with a healthy, ambitious belief in your vision, means you must make decisions and embrace the inevitability of failure.

Ironically, a perfectionist's quest for the perfect business involves navigating the most imperfect path possible. This journey helps heal those childhood wounds, as you learn to appreciate your achievements and thrive on failure.

The startup journey transforms the perfectionist mindset by redefining success and failure, ultimately fostering a healthier, more resilient approach to personal and professional growth.

Não deveria ser tão simples inserir um bug na sua aplicação e eu te conto o porquê
Tags: beginners, testing, career, developers
Published: 2024-07-09 22:33:58

Quem nunca ouviu aquela história (fictícia ou não) do dev júnior que apagou a base de dados em produção? Ou quantos de nós ao implementar aquela nova melhoria, sem perceber inseriu um bug dentro da aplicação? Normalmente, a nossa primeira atitude é culpar ou a pessoa (quando ela comete o erro) ou a nós mesmos (quando nós cometemos o erro).

Inserir bug em um sistema ou mesmo apagar os dados de produção não deveriam ser tarefas tão simples de realizar (você deve concordar comigo, não é mesmo?). Mas porque isso acontece?

### Pessoas e Processos

Acredito que a resposta para esta pergunta inicia no entendimento de que **a maioria desses erros é primeiramente uma falha de processo e não de pessoas**. Observar as falhas a partir desse ponto de vista nos ajuda muito a encontrar a verdadeira causa do erro e evitá-las (ou pelo menos reduzí-las) no futuro. 

No livro “A Startup Enxuta”, Eric Ries apresenta uma declaração bem interessante:

> *Se nosso processo de produção é tão frágil que você pode quebrá-lo logo no primeiro dia de trabalho, que vergonha por tornar isso tão fácil.*
> 

Em outras palavras, **não deveria ser tão simples inserir um bug na minha aplicação!**

### Não chore o leite derramado, escreva testes!

Ok Ramon, eu entendi que não pode ser tão fácil. Porém, será que existe um meio pelo qual eu posso dificultar o meu “eu futuro” ou até um colega de cometer o mesmo erro? Sim! E uma das maneiras seria: **escrever testes para sua aplicação!**

O desejo e urgência para corrigir esse bug deve ser o mesmo para evitar que a próxima pessoa repetisse o erro. Ao inserirmos testes na aplicação, nós estamos de alguma forma protegendo o nosso trabalho bem como o dos nossos colegas também. Ou seja, **tornando o processo de inserir bugs mais difícil**.

Sempre que um novo bug é descoberto na aplicação, podemos criar um teste específico para detectá-lo. Dessa maneira, à medida que adicionamos mais testes, nosso sistema se torna progressivamente mais robusto e menos suscetível a erros. Percebeu que isso é muito mais produtivo que apenas criticar a pessoa ou até você mesmo?

## Conclusão

Enxergar os erros como oportunidades de melhoria no processo de desenvolvimento, nos permite identificar as causas reais e implementar soluções eficazes. A criação de testes é uma das estratégias poderosas para tornar o sistema mais robusto e resiliente a novos bugs, fortalecendo continuamente o processo de desenvolvimento de software.

Efficiency of Data Structure
Published: 2024-07-10 04:16:45

Data structures are the fundamental components of computer programming, enabling efficient data organization, storage, and manipulation. Despite their importance, In this post, we will dive the world of data structures, their types, and their importance in programming.

**Data Structures vs. Data Types**

Many programmers struggle to understand the differences between data structures and data types. Data types define individual pieces of data, whereas data structures define how multiple values are organized and stored. This distinction is crucial, as it allows programmers to choose the appropriate data structure for their specific needs.

**Linear and Non-Linear Data Structures**

Linear data structures, such as arrays and linked lists, arrange elements sequentially. Non-linear data structures, like trees and graphs, don't follow a sequential arrangement. Each type has its strengths and weaknesses, making them suitable for different tasks.

**Arrays and Linked Lists**

Arrays store contiguous memory locations, enabling fast data processing. Linked lists, on the other hand, use pointers to connect nodes, allowing for easy insertion and deletion.

**Stacks and Queues**

Stacks follow the Last In First Out (LIFO) order, while queues follow the First In First Out (FIFO) order. These data structures are essential for managing data in a specific order.

**Trees and Graphs**

Trees are hierarchical data structures with nodes connected by edges. Graphs consist of vertices connected by edges, solving complex programming problems.

**Importance of Data Structures**

Data structures are essential for two main reasons: they make the code more efficient, and they make the code easier to understand. other importance include: 

- Enable efficient data storage and retrieval
- Allow for scalable software development
- Provide a framework for solving complex problems
- Help programmers write more efficient and effective code
