Introduction to Basic Web Development Skills

In this episode, Fabio Akita discusses the basic curriculum for becoming a web developer. He emphasizes the importance of starting with foundational knowledge in HTML, CSS, and JavaScript. He also highlights the need to continuously learn and stay updated in the field.

Basic Knowledge for Web Development

• Starting from scratch with HTML, CSS, and JavaScript is essential for beginners.

• Technology courses often cover Java or PHP alongside HTML and CSS.

• Building a career requires working in a team and gaining practical experience.

• The roadmap for web development skills is constantly evolving.

• The Developer Roadmap is an online resource that provides a graphical representation of essential and desirable skills for different careers within web development.

Four Parts of the Developer Roadmap

1. General Knowledge

• Front-end development focuses on visual aspects, including HTML, CSS, JavaScript, and usability.

• Back-end development deals with software functionality, business rules, integrations, and databases.

• DevOps involves managing infrastructure and deployment processes.

2. Front-end Development

• Front-end developers focus on user interfaces (UI) using HTML, CSS, JavaScript frameworks like React or Angular.

3. Back-end Development

• Back-end developers handle server-side logic using programming languages like Python or Ruby along with frameworks like Django or Ruby on Rails.

4. DevOps

• DevOps professionals manage infrastructure automation and deployment processes using tools like Docker or Kubernetes.

Learning Approach

• Use the roadmap as a checklist but focus on mastering around 20% of each topic initially to solve 80% of problems.

• Git is an essential version control tool developed by Linus Torvalds that helps manage code collaboration efficiently.

Setting up a Central Server

The importance of having a central server for efficient workflow.

Benefits of a Central Server

• A central server helps streamline workflow and improve collaboration.

• It allows for centralized data storage and easy access to files.

• Facilitates better organization and version control of documents.

Learning about Operating Systems

The significance of learning about operating systems, particularly Linux-based distributions.

Importance of Learning Linux

• While many people use Windows, it is essential to learn about Linux-based distributions.

• Virtualization tools like VirtualBox or paid versions such as Parallels can be used to run Linux on your machine.

• Running Linux in virtual machines provides the opportunity to gain hands-on experience with different distributions like Ubuntu, Fedora, or Arch Linux.

Understanding Linux Distributions

Exploring the concept of Linux distributions and their variations.

What are Linux Distributions?

• Linux refers to the kernel responsible for starting the machine, configuring devices, and offering services to applications.

• Various distributions utilize the Linux kernel but differ in application selection, configuration methods, package management, and ecosystem.

• Popular choices include Ubuntu, Mint, Fedora, Arch Linux, among others.

User Permissions and Services

Understanding user permissions and background services in a system.

User Permissions

• Users have two levels of permission: general access (user) and administrator access (root).

• Regular applications run under user privileges while system services or daemons operate with higher privileges.

Background Services

• Background services or daemons perform tasks after booting up the operating system.

• They require elevated privileges to control network connections, file systems, etc.

Managing Multiple Versions of Programming Languages

Dealing with multiple versions of programming languages on a machine.

Handling Different Language Versions

• It is crucial to manage multiple versions of programming languages, especially when working on older projects.

• For example, if a project requires Python 2.6 while your machine has Python 3 installed, you need to have both versions available simultaneously.

• Tools like pyenv or virtual environments can help manage different language versions effectively.

New Section

In this section, the speaker emphasizes the importance of understanding that each programming language consists of various components such as interpreters, compilers, libraries, and their locations on your machine. It is crucial for programmers to have control over their own machines and be familiar with tools like Git and operating systems.

Understanding Programming Languages and Components

• Each programming language is a collection of executable components such as interpreters, compilers, libraries.

• As a programmer, it is important to know where these components are located on your machine.

• Learning how to manage code using tools like Git and understanding the functioning of your operating system is essential.

• The main role of a programmer is to control machines by giving them instructions through code.

• Without having control over your system and knowing where your tools are located, you will struggle to evolve as a programmer.

This section highlights the significance of understanding programming languages and having control over one's own machine.
