A Primer on Machine Learning with Python

Over the past decade, machine learning has moved from scientific research labs to everyday web and mobile applications. Machine learning enables your application to perform previously difficult tasks, such as detecting objects and faces in images, detecting spam and hate speech, and generating smart replies for email and message applications. However, performing machine learning is fundamentally different from classical programming. In this article, you will learn the basics of machine learning and create a basic model that can predict flower species based on flower measurements. Key Points Machine learning has evolved from a scientific research lab to everyday web and mobile applications, enabling applications to perform tasks that were previously difficult to program. Machine learning relies on experience, trains models through examples, rather than

What Is a REST API?

Detailed explanation of REST API: Easily understand the most commonly used network service technologies REST, which stands for "Representational State Transfer", is currently the most widely used network service technology. Although its name is a bit abstract, the REST API is essentially a way for two computer systems to communicate using HTTP technology common in web browsers and servers. In software development, data sharing between systems is always a basic requirement. For example, when purchasing auto insurance, the insurance company needs to obtain your personal information and vehicle information, so it needs to request data from vehicle registration agencies, credit agencies, banks and other systems. All of this is done transparently in real time

How to Deploy Flask Applications on Vultr

Deploy secure Flask applications using Gunicorn, Nginx, and Let's Encrypt Flask is a Python framework for building web applications. With Flask, developers can easily define routing, process HTTP requests and responses, and render dynamic content using Jinja2 templates. It also supports extensions that allow developers to integrate features such as database access, form processing, and user authentication. This article will explain how to use Gunicorn to deploy Flask applications and implement CSRF protection and content security policies (CSP). We will also set up a reverse proxy using Nginx and apply for free SS via Let's Encrypt

JavaScript vs Python: Which One Should You Learn First?

Key Points Python syntax is more intuitive and closer to English, making it easier for beginners to get started, while JavaScript syntax contains more symbols, which may not be easy for programming newbies to understand. JavaScript is the mainstream language for web development, with a large number of libraries and frameworks, which are very valuable for those who want to work in the field. Python is very common in various fields such as AI, machine learning, and data science, and its application range is far beyond Web development. Both languages support multiple programming paradigms, but Python is generally more suitable for object-oriented programming due to its concise syntax, while JavaScript is better at event-based scripting. Taking into account the demand in the job market

Why FastAPI Full-Stack Template Is My Go-To for Modern Web Development

Python, although not the most modern programming language, is one of the most widely used languages today. An old Persian proverb: "A flower without thorns is a gift from heaven (گل بی‌خار خداست)" reminds us that everything in the world has flaws, and so do programming languages. Although Python has some performance issues (compared to compiled languages) and the notorious GIL (Global Interpreter Lock), its simplicity, large community, and rich library support more than make up for these shortcomings. Recent advances in Python's core technology have also paved the way for modern features like type hints and concurrency—features that were originally missing. Python 3.5 introduces type hints and
