    I Tried Every Hot Programming Language

    The author compares their experiences working with GoLang, Zig, and Rust through practical projects. They found GoLang easy to learn and reliable, Zig explicit and fast but lacking memory safety, and Rust challenging due to its strict memory rules but ultimately rewarding. The comparison highlights the strengths and weaknesses of each language and concludes that the best choice depends on specific use cases and team preferences.

    EP125: How does Garbage Collection work?

    Garbage collection is a crucial automatic memory management feature used in many programming languages. Java offers multiple garbage collectors tailored to different scenarios, Python employs reference counting alongside a cyclic collector to handle circular references, and GoLang utilizes a concurrent mark-and-sweep garbage collector to minimize application pauses. Additional topics include tools for designing fault-tolerant systems and key system design trade-offs.

    Scaling One Million Checkboxes to 650,000,000 checks

    One Million Checkboxes (OMCB) is a website that scaled from a few expected users to over 650 million checks within days. The architecture involved using Redis for state management, nginx for static content and reverse proxy, and Flask for API handling. The site faced several challenges including unexpected high traffic, Redis connection issues, and bandwidth costs. Solutions included adding more servers, batching updates, using a connection pool, and eventually rewriting the backend in Go, which significantly improved performance. The project emphasized learning and fun over perfect solutions, leading to valuable scaling insights.

    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.

    Performance Benchmarking: gRPC+Protobuf vs. HTTP+JSON

    A performance benchmarking experiment compared gRPC with Protocol Buffers to HTTP with JSON for microservices communication in Go. The tests, run on a local machine, showed that HTTP/2 was slower than gRPC, which in turn was slower than HTTP/1. Despite these results, Protocol Buffers over gRPC remain an effective choice for inter-service communication due to its structured format.
