Good ways to teach software development?
Tags: discuss, learning, teaching, education
Published: 2024-07-10 02:00:49

Hello!

Just a few weeks ago I started to organize myself to teach others about software development, the basics, computational thinking, backend, frontend, some professional tips and other topics from scratch. For now I only have a general idea and roadmap about what and how to teach, but nowadays there are a lot of tools to create good classes both online and face to face, but I lack experience to create good classes, I have little experience and I have been teaching using a whiteboard and the personal computer showing lines and lines of code with some simple examples. In your opinion, what tools are great for making a class fun and capturing the student's attention? I would like to avoid boring him by showing only lines of code and not falling into the typical examples when someone starts coding.

I know some AI tools but I don't have enough experience to make a great class, so could you share some tips or tools to be able to teach and still make it a great experience? please.

I appreciate any tips, thanks!

What integrated circuit chip is
Tags: programming
Published: 2024-07-10 02:17:17


What it is
An [integrated circuit chip](https://www.blikai.com/blog/components-parts/integrated-circuit-chip-types-applications-and-faq) design that integrates compound semiconductors with silicon complementary metal-oxide semiconductor (CMOS) technology, which is the basis for most of today’s integrated circuits.

Why it matters
Over 20 years ago, Eugene Fitzgerald of MIT developed strained silicon technology, overcoming the then-existing limits on the number of transistors on a computer chip. This innovation allowed Moore’s Law, which predicts the doubling of transistors on a chip every 18 months, to continue. However, silicon and compound semiconductor devices have now reached their natural limits and cannot independently provide the functionalities needed for further innovation. Fitzgerald, who is also the CEO and director of the Singapore MIT Alliance for Research and Technology (SMART), is developing an integrated circuit chip design that exceeds the natural capacity of silicon. By incorporating higher-performance compound semiconductors into integrated silicon circuit designs, it will be possible to create chips that drive advancements in product, system, and software design. These new chips will play a crucial role in the next generation of user interfaces for virtual and augmented reality, as well as 5G and 6G connectivity applications.

Decode the 10K Resistor Color Code Like a Pro!
Tags: webdev
Published: 2024-07-10 02:39:54

Discovering the secret language of resistors, particularly the [10k resistor color code](https://www.blikai.com/blog/components-parts/10k-resistor-color-code-everything-you-need-to-know), is like cracking a cryptic code.

Think of resistors as traffic wardens for electrons in an electrical circuit. They control the flow of current and lower voltage levels within circuits. To put it in a more relatable way, they're like the speed bumps on your neighborhood roads, slowing down speeding cars (or in this case, electrons).

Consider this: you're building a model car for your kid. You'll need resistors to ensure the mini lights in the model don't burn out due to excess voltage. Thus, resistors are a vital component of all electronic devices, from the smallest toys to large supercomputers.

Different Types of Resistors
Just as there are various types of speed bumps, there are numerous types of resistors. They come in different forms, sizes, and resistance values, such as carbon film, metal film, wirewound, and SMD. The choice depends on the requirement, precision, and application.

Among the various resistors, our hero for the day is the 10K ohm resistor. It's commonly used in many electronic circuits due to its versatility and ideal resistance value.

Understanding Resistor Color Codes
The rainbow-like bands on resistors aren't just for decoration. They're a secret language, revealing the resistor's resistance, tolerance, and sometimes even temperature coefficient.

Each color represents a number from 0 to 9. These numbers, read in a particular order, help you understand the resistor's resistance value and tolerance.

Resistors can have 4, 5, or 6 bands. The 4-band resistors are like the original trilogy of Star Wars, widely recognized and adored. But then came the prequels and sequels, the 5-band and 6-band resistors, offering more precision and information.
Polyester vs. Polypropylene: Which One Is the Better Choice for a Rug?
Tags: webdev
Published: 2024-07-10 02:48:41

A rug is a necessary element in any home, adding a touch of elegance and style. Before you buy one, it's important to understand [the difference between polyester and polypropylene rugs](https://www.blikai.com/blog/components-parts/polyester-vs-polypropylene-capacitors-explained).

These two types of rugs are made from different materials. Polyester is made from synthetic fabrics, while polypropylene is made from natural fibers.

Polyester rugs are cheaper than polypropylene rugs, but they are not as durable. Polypropylene is more expensive, but it's also more durable.

Polyester is the more popular choice for a rug because it is a synthetic fiber, meaning it is made from a series of connected molecules that are not derived from plants. Polyester rugs are often cheaper than rugs made from natural fibers, and they last longer due to their synthetic properties.

One downside to polyester rugs is that they can be difficult to clean. Polypropylene rugs, on the other hand, are made from a petroleum-based polymer that is less likely to cause allergies than polyester. They also tend to be more expensive than polyester rugs, but they are easy to clean and last longer. Ultimately, it is important to decide what type of rug is best suited for your needs.

ACID: O Pilar dos Bancos de Dados Relacionais
Tags: datascience, sql, postgres, community
Published: 2024-07-10 15:05:00

# O Que é ACID em Bancos de Dados Relacionais?

Se você já trabalhou com bancos de dados relacionais, provavelmente já se deparou com a sigla ACID. Mas o que exatamente isso significa e por que é tão importante? Vamos explorar cada componente de ACID e entender o seu papel nos sistemas de banco de dados. 

### O que é ACID?
ACID é um acrônimo que representa quatro propriedades fundamentais garantidas pelos sistemas de banco de dados relacionais para garantir a integridade e a confiabilidade das transações. Estas propriedades são: Atomicidade, Consistência, Isolamento e Durabilidade.

### Componentes do ACID

#### Atomicidade (Atomicity):
- **Conceito:** Assegura que todas as operações dentro de uma transação são completadas com sucesso ou nenhuma delas é aplicada.
- **Exemplo real:** Em uma transação de transferência bancária, se a transferência do valor da Conta A para a Conta B falhar, nenhuma das contas deve ser alterada.

#### Consistência (Consistency):
- **Conceito:** Garante que uma transação leva o banco de dados de um estado válido para outro estado válido, preservando as regras de integridade.
- **Exemplo real:** Após uma transação, todas as regras de integridade, como restrições e gatilhos, são respeitadas. Se um depósito for feito, o saldo total do banco deve refletir essa mudança.

#### Isolamento (Isolation):
- **Conceito:** Assegura que as operações de uma transação são isoladas de outras transações simultâneas. As transações não devem interferir umas com as outras.
- **Exemplo real:** Se duas pessoas estão comprando o último item disponível em uma loja online ao mesmo tempo, o sistema deve garantir que apenas uma transação finalize a compra.

#### Durabilidade (Durability):
- **Conceito:** Garante que uma vez que uma transação foi concluída com sucesso, suas alterações são permanentes, mesmo em caso de falha do sistema.
- **Exemplo real:** Após a confirmação de um pedido em um e-commerce, os detalhes do pedido devem permanecer registrados, mesmo que ocorra uma queda de energia logo em seguida.

### Importância do ACID
- **Confiabilidade:** ACID é crucial para garantir que os bancos de dados se comportem de maneira previsível e confiável.
- **Integridade de Dados:** Mantém a integridade dos dados, assegurando que eles não fiquem em um estado incorreto.
- **Segurança:** Proporciona uma camada adicional de segurança, garantindo que as transações sejam corretamente registradas e mantidas.

### Conclusão
As propriedades ACID são muito importante nos bancos de dados relacionais, já que garantem que as transações serão realizadas de forma segura, confiável e eficiente. Compreender ACID é fundamental para qualquer profissional que trabalhe com bancos de dados, pois garante a integridade e a consistência dos dados, aspectos que são vitais em qualquer aplicação crítica.

Aula 00.py uma breve introdução
Tags: python, algorithms, datastructures, tutorial
Published: 2024-07-10 20:20:49

Quando começamos a estudar algo, muitas vezes queremos pular direto para os tópicos avançados e acabamos esquecendo da base. Isso ocorre em todas as áreas, principalmente na área de T.I.

Ao iniciar os estudos em programação, muitos de nós já queremos construir sistemas complexos, como os da Netflix ou da Uber, sozinhos, e em alguns meses já imaginamos ter milhões na conta e estar em alguma praia do Caribe.

Durante o boom da área, muitos cursos se aproveitaram dessa mentalidade, oferecendo promessas como "Construa sua pokedex e torne-se um profissional sênior em 6 meses". Muitas pessoas, por desconhecimento ou buscando atalhos, caíram no papo dos coaches.

Nesse período, muitas pessoas entraram no mercado. No entanto, hoje o cenário é diferente e as empresas buscam profissionais com experiência e uma base sólida para resolver problemas. Infelizmente, os coaches só ensinaram a copiar e colar sem nenhuma base.

### O que vamos aprender?
Vamos aprender lógica de programação, algoritmos e estruturas de dados, que são a base para se tornar um programador capaz de resolver problemas, pois é isso que um programador faz: resolve problemas. Você pode até achar isso chato, mas é essencial no dia a dia.

### Básico sobre o Python
O [Python](https://www.hostinger.com.br/tutoriais/python-o-que-e) é uma linguagem de programação criada antes mesmo do Java por Guido van Rossum. Ela é uma linguagem de alto nível, o que significa que é muito semelhante à linguagem humana. Veja o exemplo abaixo:

```py
print("Olá, sou um script em Python que imprime uma mensagem na tela")
```
Além de ser simples de aprender, é uma linguagem muito versátil, utilizada para análise de dados, scripts e back-end. Python também é usado por grandes e pequenas empresas como Google, Meta, OpenAI e muitas outras, possuindo uma comunidade bastante ativa com diversos recursos como ebooks, livros e discussões em fóruns.

### O que vamos precisar?
Precisaremos apenas de uma conta no [Google Colab](https://colab.research.google.com/), uma plataforma que nos permite executar códigos Python de maneira simples. Caso prefira, sinta-se à vontade para instalar o Python e o VSCode em seu PC e codar por ele.

Cybersecurity Awareness: Protecting Your Digital Life
Published: 2024-07-10 03:29:24

In today's digital age, our lives are closely intertwined with the internet, but this connectivity also comes with significant security challenges. Protecting personal information and data security has never been more crucial. Here are some practical cybersecurity tips to help safeguard your digital life:

**Use Strong Passwords**
Think of your password like the lock on your front door. A strong password should be complex, combining letters, numbers, and symbols. For example, avoid using passwords like "123456" or "password," as they are too easy to crack.

**Beware of Phishing Attacks**
Imagine receiving an email that appears to be from your bank, stating there's unusual activity on your account and prompting you to click a link to verify. Don't rush to click! It could be a phishing email crafted by scammers aiming to trick you into revealing personal information. Remember, a legitimate bank will never ask for your password or personal information via email.

**Keep Software Updated**
 When your phone, computer, or other devices prompt you to update software, don't ignore it. These updates often patch known vulnerabilities and help prevent hackers from gaining access.

**Enable Two-Factor Authentication**
 Just like needing two keys to open a bank safe deposit box, enabling two-factor authentication means besides your password, you'll need to input another form of verification, such as a text message code or app-generated token, to confirm your identity.

**Regularly Back Up Data**
 Ever wondered what would happen if your computer fell victim to ransomware, encrypting all your files? Regularly back up important files to an external hard drive or cloud storage to mitigate such risks.

Cybersecurity isn't just the responsibility of IT professionals; it's everyone's responsibility. By following these simple steps, you can effectively protect your digital life.
Getting Data Through Using API in JavaScript.
Tags: javascript, webdev, beginners, programming
Published: 2024-07-10 03:34:49

When building web applications, making HTTP requests is a common task. There are several ways to do this in JavaScript, each with its own advantages and use cases. In this post, we’ll explore four popular methods: `fetch(), axios(), $.ajax()`, and `XMLHttpRequest()`, with simple examples for each.

**1. Using fetch()**
The `fetch()` function allows you to request HTTP to fetch resources from a network. It uses promises, which makes it easier to handle asynchronous operations.

_Example_

```
fetch('https://api.example.com/data')
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error('Error:', error));
```
**2. Using Axios()**
`axios()` is a popular `HTTP` client for making requests from browsers or `Node.js `applications. It is similar to the built-in `fetch()` API but includes additional features such as request and response interceptors, automatic `JSON `parsing, and more.

_Example_

```
axios.get('https://api.example.com/data')
  .then(response => console.log(response.data))
  .catch(error => console.error('Error:', error));
```

**3. Using $.ajax()**
If you’re working with `jQuery`, you can use the `$.ajax()` function to make HTTP requests. It provides a simple interface for making AJAX requests and handling responses.

_Example_

```
$.ajax({
  url: 'https://api.example.com/data',
  method: 'GET',
  success: function(data) {
    console.log(data);
  },
  error: function(error) {
    console.error('Error:', error);
  }
});
```
**4. Using XMLHttpRequest()**
The `XMLHttpRequest` object provides an easy way to fetch data from a URL without a page refresh. It's a bit lower-level than `fetch()` or libraries like Axios, but it's still widely used in many applications.

_Example_

```
var xhr = new XMLHttpRequest();
xhr.open('GET', 'https://api.example.com/data', true);
xhr.onload = function() {
  if (xhr.status >= 200 && xhr.status < 300) {
    console.log(JSON.parse(xhr.responseText));
  } else {
    console.error('Error:', xhr.statusText);
  }
};
xhr.onerror = function() {
  console.error('Request failed');
};
xhr.send();
```
In this example, we create a new XMLHttpRequest, open a GET request, and handle the response by checking the status code and parsing the response text.
