Nim doesn't have a lot of options for building HTTP APIs with the kind of batteries-included developer experience you get in frameworks like FastAPI or Express with Swagger middleware. mummy is a fast, solid HTTP/WebSocket server library for Nim (my fork with the additions below is at github.com/isaiahpeter/mummy ) — but out of the box, it doesn't generate OpenAPI specs, validate request bodies, or give you typed path parameters. So I forked it and added those. This post walks through what I built, why, and what I learned extending an existing Nim library instead of starting from scratch. Why mummy, and why OpenAPI I wanted a Nim backend for a few projects (a contact-form API, a todo API demo) and kept missing three things I'd take for granted in other ecosystems: Auto-generated API docs — a /docs endpoint you can actually hand to someone, generated from your routes instead of hand-written. Typed path parameters — pulling id out of /users/{id} as an int without manual parsing and error handling in every handler. Request validation — rejecting a bad JSON body before it reaches your handler logic, with a schema to back it up. mummy is fast and minimal by design, which is exactly why it was worth extending rather than replacing. What I added OpenAPI spec generation. I added openapi_schema.nim and openapi_router.nim , which let you wrap routes in an OpenApiRouter and attach a summary, tags, and a response schema via schemaOf . The router serves both /openapi.json and a browsable /docs page generated from your actual route definitions — so the docs can't drift out of sync with the code the way hand-written API docs do. Typed path parameters. pathParam[T](request, "id") pulls a path segment and parses it as the type you ask for, with a clean 400 response if parsing fails. One gotcha worth flagging if you try this yourself: in this Nim version, the generic dot-call form ( request.pathParam[int]("id") ) doesn't parse — you have to call it as pathParam[int](request, "id") in

Introduction: Unveiling littlebag Meet littlebag , a reactive UI framework that defies conventional expectations by packing essential features into a mere 343 bytes (minified and brotlified). This isn’t just a technical curiosity—it’s a proof of concept that challenges the notion that UI frameworks must be bloated to be functional. littlebag includes: Reactive state management via state and effect , enabling dynamic updates without manual DOM manipulation. An html element factory that inherently supports reactivity, reducing boilerplate code. Conditional rendering with keyed , allowing efficient updates to specific UI segments. Reactive lists using each , simplifying the handling of dynamic data collections. TypeScript declarations , ensuring type safety and developer productivity. The framework’s size is achieved through aggressive tree-shaking and code minimization , stripping away all non-essential logic. However, this comes at a cost: performance limitations due to the absence of optimizations like virtual DOM diffing or batch updates . Each reactive update triggers direct DOM manipulation, which can lead to layout thrashing —a mechanical process where frequent reflows and repaints cause frame rate drops, making the UI feel sluggish. Inspired by VanJS (1 kB) and its dependency on an additional 1.2 kB library (Van X), littlebag aims to eliminate such overhead. Yet, its current state is experimental. Without user feedback, it risks remaining a niche project, failing to address its performance bottlenecks or evolve into a viable alternative to larger frameworks. The creator’s plan to add Server-Side Rendering (SSR) hinges on community interest, but SSR itself introduces complexity—requiring a custom DOM implementation to avoid client-side hydration costs. If users engage, littlebag could become a lightweight SSR solution; if not, it may stagnate as a curiosity. The stakes are clear: littlebag’s utility depends on whether it can balance its minimalism with practical

What happens when a machine no longer needs to be trained to see something new? That's the quiet question sitting underneath this week's news, buried next to a less invasive brain implant and a handful of robots getting tougher for the real world. Neuralink says it's completed its first "transdural" brain implant, a surgical approach built to reduce trauma during the procedure. As someone who spends a lot of time thinking about how you get sensors close to a human eye without hurting anyone, I find these less-invasive-implant strategies worth watching, because the surgical-risk problem is basically the same one we wrestle with in ophthalmic hardware. Vision is getting less invasive too, in its own way. Roboflow rolled out text-prompt object detection built on SAM3 (Meta's latest segmentation model): you type the class of object you want "forklift," "cracked tile," whatever, and it returns boxes and masks without you collecting a single training image first. That's a real shift. For most of computer vision's history, teaching a model to recognize something new meant labeling hundreds of examples before you could even start; this collapses that step into a sentence. The same week brought several applied builds using the same detect-then-orchestrate pattern: a drone system that patrols for intrusions, a pipeline that inspects transmission lines for damaged cables, and an airport tool that spots foreign debris on the tarmac. The Robot Report's roundup of June's biggest robotics stories leaned heavily on humanoid robots companies going public, new deployments, and production milestones stacking up faster than would have seemed plausible a few years ago. Apptronik unveiled its Apollo 2 humanoid alongside a dedicated data-collection facility built so the robot keeps learning after it's deployed, not just during initial training which quietly answers one of the harder questions in robotics: how do you keep a system improving once it's out of the lab?
