    I made a multiplayer game from scratch because no one is hiring junior devs.

    A junior developer, frustrated with the job market, built a multiplayer browser game to enhance their resume. The game features turn-based tactics on a 2D hexagonal grid with limited player visibility and a shrinking map. The client-side is developed using TypeScript and HTML5 canvas, while the server-side is implemented in Golang using websockets. The project includes complex features like responsive UI, pathfinding, animations, and real-time multiplayer logic. Despite some challenges, including iOS websocket issues, the game is functional and available to play.

    How I Stopped Worrying and Learned to Love Go Interfaces

    Go interfaces provide a way to define behavior without specifying the method of implementation. They improve code flexibility and cleanliness by allowing different types to satisfy the same interface as long as they implement the required methods. Understanding and using interfaces are essential for scalable and maintainable code. Example implementations include Animal types making different sounds and Shapes calculating area and perimeter.

    SQLc is the perfect tool for those who don't like ORMs

    SQLc is an efficient tool for developers who prefer writing raw SQL queries over using ORMs. It allows for type-safe SQL query generation, fitting neatly within the repository design pattern. SQLc supports multiple programming languages (TypeScript, Kotlin, Python, and Go) and SQL engines (Postgres, MySQL, SQLite). It eliminates boilerplate code, making database interactions more manageable and reusable across codebases. By using SQLc, developers can maintain full control over queries while ensuring type safety and reducing development time.

    Fuzz Testing Go HTTP Services

    Fuzz testing, or fuzzing, is an automated software testing technique used to find bugs, crashes, and security vulnerabilities by inputting large amounts of random data into a program. It is now integrated into Go’s standard library as of Go 1.18, making it part of the regular testing package. Fuzz testing can reveal bugs that traditional testing might miss and is a recommended practice for improving the robustness of code, including HTTP services. The post provides step-by-step instructions for creating fuzz tests in Go, including an example for fuzzing HTTP handlers using Go's `httptest` package.
