   Sqlite Is Getting So Good

   The post dives into a new multi-tenant architecture and issues a scalability challenge for a serverless database based on a fork of SQLite. It emphasizes the advantages of deterministic simulation testing (DST) and highlights the importance of not reinventing the wheel unless mission-critical. It also discusses the application of Rust and its borrow checker for improved safety and performance, the implementation of DST for bug detection, and the decision-making process behind choosing Rust over Zig for the rewrite project.

   Lightweight Kubernetes and Wasm is a Perfect Combo

   Recent advancements have introduced lightweight Kubernetes distributions like Rancher Labs k3s and Canonical's Microk8s. Combining these with WebAssembly-based SpinKube offers high efficiency, especially for lower-powered hardware or virtual machines. SpinKube's serverless design allows apps to start in half a millisecond, making it suitable for high-density deployments, cost-saving on infrequent services, and efficient edge computing.

   Writing an HTTP Router for AWS Lambda Functions From Scratch With Go

   Deploying REST APIs using serverless architecture with AWS Lambda can deliver advantages like pay-per-request pricing and no infrastructure management but also presents challenges such as cold starts and vendor lock-in. To optimize HTTP request routing in Lambda functions, the author implemented a custom router called LambdaMux using a radix tree for efficient matching, competing with existing solutions such as aws-lambda-go-api-proxy and LmdRouter. Benchmarks show LambdaMux offers performance improvements, particularly in high-throughput scenarios. Future enhancements may include adding middleware support and query parameter parsing.

   IndieWeb Link Sharing

   Sharing content on IndieWeb can be inconvenient compared to social media. To improve this, the author adapted a link sharing technique involving a Javascript bookmarklet, a sharing form, and a serverless function for their Eleventy and Netlify setup. This method facilitates quick post creation and can be used on both desktop and mobile by integrating a PWA share target.

    Persistent serverless state machines with XState and Restate

    XState is a powerful JavaScript framework for building state machines, popular for modeling frontend state. Restate, a new durable execution engine, allows converting simple imperative code into fault-tolerant distributed systems. By combining XState and Restate, developers can create ‘virtual state machines’ that store state durably and wake up only to process events, making them suitable for backend processes. This approach simplifies business logic modeling, making it possible to handle complex tasks, such as payments, through state machines without persistent resource usage. This integration is deployable across different environments, enhancing code resilience and scalability.
