Enums in Golang: Techniques, best practices, & use cases

Categories

Tags programming app-development programming golang

Enums provide a way to represent a set of named constants. While Go lacks a built-in enum type, developers can emulate enum-like behavior by constants/custom types. Enums play a vital role in programming languages, providing a concise and expressive way to define a set of named constants. While some languages like Java or C# offer built-in support for enums, Go takes a different approach. In Go, enums are not a native language feature, but developers have several techniques at their disposal to achieve similar functionality. By Thuoc Nguyen.

The article then describes in some depth:

  • Understanding Enum
  • Benefits and limitations of Enums
  • Implementing Enum-like functionality in Golang
  • Comparison of techniques
  • Best practices of Golang Enums
  • Real-world use cases

Throughout this guide, we explored various methods for implementing enums in Go language and discussed their respective benefits, limitations, and best practices. In essence, enums in Go empower developers to write cleaner, more maintainable code by providing a structured way to represent a fixed set of values. By understanding the different techniques and best practices outlined in this guide, developers can leverage enums effectively to enhance their Go projects. Good read!

Type conversion in Golang: How to convert data types in Go?

Categories

Tags how-to app-development programming golang

Type conversion is the process of converting a value from one data type to another. Explicit type conversion in Go ensure compatibility between different data types.By Huy Nguyen.

In many cases, you will need to convert data types. Professionals may find Golang’s type conversion notion easy to grasp, but beginners may find it difficult to grasp anything at first. The fact that Golang has a distinct approach to type conversion is probably to blame for this. In this post, we will talk about type casting, also called a conversion, in the Go programming language.

What is catured in the article:

  • What is type conversion?
  • Introduction to Go data types
  • What is the need for type conversion in Golang?
  • Types of type conversion in Golang
  • Scenarios Requiring To Convert Data Types
  • Sample code
  • Compile error on implicit type conversion

In summary, handling different types of data in Go involves some careful steps based on how the language works. It’s important for Go developers to grasp the details of various data types, figure out when to use direct or clear conversions, and identify situations where converting types is necessary.

  • What is meant by code refactoring
  • Why is it important
  • What are the benefits of code refactoring
  • When to refactor code
  • What aspects of the code is refactoring aimed at
  • How do you refactor code

Code refactoring is the process of restructuring existing code, while its outward functionality remains unchanged. By refactoring, you can simplify complex code structures, reduce code redundancy, and enhance code reusability. Visual Studio offers many tools to help refactor your C++ code. This article will delve into these tools, using the bullet3 open-source code as an example. By Mryam Girmay.

The tools reviewed list includes:

  • Rename
  • AI-Powered rename suggestions
  • Change signature
  • Extract function
  • Implement pure virtuals
  • Create declaration / definition
  • Move definition location
  • Convert to raw string literal
  • Convert macros to constexpr
  • GitHub Copilot for refactoring

To utilize GitHub Copilot for refactoring, begin by identifying the segment of code you wish to refactor. This could be a function, a class, or even a single line of code. Once identified, right-click on the selected code and request assistance from Copilot to refactor it. The command can be tailored to your specific needs. Upon generating a suggestion for the refactoring, it’s crucial to review this carefully. Make any necessary adjustments to ensure it aligns with your coding standards and project requirements. Once you’re satisfied with the proposed refactoring, proceed to implement the changes in your code. Nice one!

12 secure browsers that protect your privacy in 2024

A secure browser that protects your privacy is a critical tool for staying safe online and keeping your data secure from third parties. We have been reviewing, testing, and ranking browsers for the past six years and this guide contains the latest recommendations for 2024. By Alex Lekander.

Do you want a secure browser that truly keeps your data private? Well, you may be surprised by how much of your data is actually getting exposed. Many browsers today are actually data collection tools for advertising companies. This is the case for Google Chrome, the largest and most popular browser. By collecting data through your browser, these companies can make money through their advertising partners with targeted ads. We see this same privacy-abusing business model with search engines, email services, and even free mobile apps.

In this section we will examine the best browsers based on two main factors - security, privacy. The list of browsers includes:

  • Brave: The most secure and private browser (for both desktop and mobile)
  • Firefox (when modified and tweaked for privacy)
  • Tor browser
  • Ungoogled Chromium browser
  • LibreWolf – A private and secure fork of Firefox
  • Mullvad Browser – A privacy collaboration between Mullvad and Tor

… and more. When using “private” or “incognito” browsing mode in your browser, your real IP address and location are still being revealed to every website, ad, and tracker that loads in your browser. Additionally, all your activities remain visible to your internet service provider (ISP). And at least here in the United States, ISPs log everything you do online and share the data with many other parties. This is why it’s critical to use a good VPN for basic digital privacy.

How Google's AI model Gemini got its name

Categories

Tags google ai how-to cloud frameworks

Gemini got its first mention at I/O in 2023, when we briefly shared our first natively multimodal model was in training and already showing impressive capabilities. One year later, we’ve brought Gemini models to Search, Ads, Workspace, Pixel and more. As Gemini continues to make a name for itself, we wondered, where did that name come from? To find out, we asked the Google DeepMind team to share the origin story behind why they called it “Gemini.” By Ari Marini.

Early on, a placeholder title for the project was “Titan,” the name of Saturn’s largest moon. “I wasn’t a huge fan of that name,” says Jeff Dean, Gemini’s co-technical lead. But it gave him an idea — or perhaps a sign — for a name grounded in space. Developed by DeepMind and Google Brain teams, Gemini aims to advance AI research.

Gemini is Latin for “twins.” In astronomy, it’s the name of a constellation associated with Greek mythological twins Castor and Pollux, for which its two brightest stars are named. Naturally, then, the meaning behind our AI model’s name is two-fold. For one, a key characteristic of the Gemini zodiac sign is a dual-natured personality, capable of adapting quickly, connecting to a wide range of people, and seeing things from multiple perspectives — themes well suited for what was happening at Google at the time.

“The Gemini effort came about because we wanted to bring our teams working on language modeling closer together,” Jeff says. “I felt the twins aspect of the name ‘Gemini’ was a great fit. The twins here are the folks in the legacy Brain team and the legacy DeepMind team, who started to work together on this ambitious multimodal model project.” The other inspiration for the name is also space-related: NASA’s early moonshot program, Project Gemini, which lasted from 1965 to 1968.
