Exploring Unicode with Go and Vue.js

Unicode: The cornerstone of modern computing, ensuring that text in any language, style, and even emoji can be consistently represented and manipulated. This article will explore the Unicode standard and use Golang and Vue.js to develop a project that uses Unicode table offsets to convert text into bold, italic, bold italic and underline styles, providing a practical and efficient text processing method. Project structure Golang backend Handles requests from the frontend, applying transformations to text based on Unicode table offsets. Vue.js front end Provides a simple interface where users can enter text, send it to the backend, and view the styled results. File structure TextCo

Go Channel Unlocked: How They Work

In-depth Golang Channel: Implementation principles and performance optimization suggestions Golang's Channel is a key component of its CSP concurrency model and a bridge for communication between Goroutines. Channel is frequently used in Golang, and it is crucial to have a deep understanding of its internal implementation principles. This article will analyze the underlying implementation of Channel based on the Go 1.13 source code. Basic usage of Channel Before formally analyzing the implementation of Channel, let’s review its basic usage: package main import "fmt" func main() { c := make(

Building a Semantic Search Engine with OpenAI, Go, and PostgreSQL (pgvector)

In recent years, vector embeddings have become the basis of modern natural language processing (NLP) and semantic search. Instead of relying on keyword searches, vector databases compare the "meaning" of text through numerical representations (embeddings). This example demonstrates how to create a semantic search engine using OpenAI embedding, Go, and PostgreSQL with the pgvector extension. What is embedding? An embedding is a vector representation of text (or other data) in a high-dimensional space. If two pieces of text are semantically similar, their vectors will be close to each other in this space. By storing embeddings in a database like PostgreSQL (with pgvector extension), we can perform similarity searches quickly and accurately. Why choose
