   MVC vs DDD: Go Language Architecture Deep Dive

   Compares MVC and DDD architectural patterns for Go applications, examining their structural differences, code organization approaches, and use cases. MVC organizes code by technical layers (Controller/Service/Repository) and suits smaller systems with stable requirements, while DDD structures code around business domains with four layers (Interface/Application/Domain/Infrastructure) and better handles complex business logic. The guide provides detailed directory structures, code examples, and implementation best practices for both patterns in Go, highlighting that MVC offers simplicity and rapid development while DDD provides better scalability and maintainability for complex systems.

   The NestJS Handbook – Learn to Use Nest with Code Examples

   NestJS is a progressive Node.js framework that combines object-oriented, functional, and reactive programming paradigms to build scalable server-side applications. Built on top of Express or Fastify, it provides a structured architecture using modules, controllers, and providers with built-in dependency injection. The framework offers TypeScript-first development, decorators for routing and validation, middleware support, guards for authorization, exception filters for error handling, and interceptors for response transformation. It includes comprehensive database integration options with TypeORM, Mongoose, and Prisma, along with built-in testing capabilities and CLI tools for code generation.

   APIs Versioning

   API versioning is essential for managing changes without breaking existing client applications. The guide covers two main strategies: additive changes (backward-compatible modifications) and explicit versioning (maintaining multiple API versions simultaneously). Implementation methods include URL path versioning, custom headers, and query parameters, with URL path being most common. Semantic versioning (Major.Minor.Patch) provides clear communication about change types. Proper lifecycle management involves setting deprecation timelines and using tools like OpenAPI specification and API gateways to automate version management and detect breaking changes.

   How server actually works?

   NGINX serves as a powerful web server and reverse proxy that handles three critical functions: load balancing (distributing traffic across multiple servers using methods like round robin and least connections), caching (storing frequently requested content for faster delivery), and security (encrypting communications and hiding backend infrastructure). The article explains how these features work together to keep websites fast and reliable, using real-world analogies like restaurant kitchens and nightclub bouncers to make complex concepts accessible to beginners.

   We accidentally built a backend framework for LLMs

   WunderGraph accidentally created a backend framework for LLMs while solving API orchestration challenges. Their Cosmo Plugins system uses LLMs to generate proxy code that connects non-GraphQL services to a unified Supergraph, enabling companies to build modular monoliths or microservices without rewriting existing REST APIs. The framework leverages GraphQL Federation to create a single API entry point from multiple services, reducing complexity and API calls while maintaining deployment flexibility.

   Golang vs C#: Backend Battle - What Top Companies Choose

   Go and C# represent different philosophies for backend development. Go offers superior memory efficiency (25MB vs 162MB), faster initial response times, and simpler deployment with 6MB container images. C# provides a mature ecosystem, comprehensive tooling, and better enterprise integration. Go excels in microservices and cloud-native applications, while C# dominates desktop applications and enterprise systems. Performance differences narrow under sustained load, with both languages suitable for production workloads. The choice depends on team expertise, infrastructure, and specific project requirements rather than absolute performance metrics.

   Working on databases from prison: How I got here, part 2.

   A software engineer shares his remarkable journey from incarceration to joining Turso as a database developer. After enrolling in a prison college program that provided computer access, he rediscovered programming and began contributing to open source projects. Through Maine's remote work program for inmates, he first worked at Unlocked Labs before becoming a major contributor to Turso's Project Limbo, a SQLite rewrite. His dedication to learning database internals and consistent contributions eventually led to a full-time position at Turso, demonstrating how determination and skill development can create unexpected career opportunities even in challenging circumstances.

    This Open Source Tool Could Save Your Data Team Hundreds of Hours

    CocoIndex introduces automatic schema inference for Qdrant vector databases, eliminating manual collection setup. The tool uses declarative dataflow programming to automatically infer and manage target schemas from flow definitions, supporting incremental processing with a high-performance Rust stack. Developers can now define data transformations in ~100 lines of Python without manually configuring collections, tables, or indexes across multiple storage systems including Postgres, Neo4j, and Kuzu.

    Node has a BUILT-IN sleep function...

    Node.js has a built-in setTimeout function in the timers/promises module that eliminates the need for custom sleep functions. Instead of creating a custom promise-based sleep utility that wraps setTimeout, developers can directly import and use the promisified setTimeout from node:timers/promises, providing the same functionality with cleaner, more maintainable code.
