Developer builds free browser-based gravity simulator for students learning physics

·1 views

A developer created Newton's Orchard, a free browser-based gravity and space simulation, after his fifth-grade son exhausted available tools used in his STEM class. The app was built over the summer as a natural progression from PhET's 2D gravity simulations. Newton's Orchard features editable celestial bodies, preset experiments, deterministic time scrubbing, and completable missions that unlock new content like black holes. Users can also submit their own creations to a public gallery. The source code is openly available on GitHub, and the developer is seeking feedback to improve its educational value for students.

Developer shares local AI model setup running on M4 Pro Mac Mini

A developer has published a detailed walkthrough of their personal local AI model setup built around Apple's M4 Pro Mac Mini. The blog post, shared on Hacker News, outlines the tools and configuration used to run large language models locally without relying on cloud services. Running AI models locally offers benefits such as privacy, cost savings, and offline access. The setup leverages the M4 Pro chip's unified memory architecture, which is well-suited for inference workloads. The post attracted community attention on Hacker News as interest in local AI deployments continues to grow.

10 MCP Servers Developers Should Know for AI-Assisted Coding in 2026

A developer roundup highlights ten Model Context Protocol (MCP) servers considered most useful for AI-assisted coding workflows in 2026. The list was compiled based on public adoption, active maintenance, official backing, and practical problem-solving for developers. Top picks include Context7 for library documentation lookup, Chrome DevTools MCP for live browser debugging, Playwright MCP for browser automation, and the GitHub MCP Server for repository and pull request management. Other notable entries cover cloud platforms and services such as Supabase, AWS, Vercel, and Cloudflare, alongside tools for code navigation and diagramming. The author advises users to exercise caution when installing any MCP server, recommending they review executed commands and test on non-production codebases first.

How a Content Pipeline's Batch Runner Silently Misreported Completion for Months

A batch runner built for a content pipeline on 16 March 2026 included resumability features from day one, yet the system remained functionally broken for three more months. The core problem involved four distinct bugs that each caused the runner to falsely believe work was already finished, including a quota error that returned an empty result instead of raising an exception, leading the pipeline to record missing content as successfully produced. Three separate parts of the stack independently handled rate-limit errors using different string-matching logic, meaning the same error could be caught or missed depending on where it surfaced. The team also had to manage stale 'running' states left behind by killed runs, as well as separate ownership of entity state and lock files — a distinction discovered only after a failure in production. The fixes for all four bugs landed in a single day, underscoring how resumability in batch pipelines differs fundamentally from retry logic and requires explicit state design.

Developer tests demand for USPTO trademark watch API before building it

A developer is conducting a public demand test for MarkWatch, a proposed API designed to simplify access to USPTO trademark data. The USPTO's Trademark Status & Document Retrieval system is free and authoritative but is widely criticized for being fragmented, rate-limited, and lacking any notification mechanism. MarkWatch aims to offer clean JSON status lookups, watch lists, and webhook or email alerts to replace manual docket monitoring currently done by attorneys and brand teams. Planned tiers range from a free option with 250 monthly lookups to a $49/month Pro plan with webhooks and bulk export, though no product has been built yet. Interested users can signal intent by selecting a pricing plan on the project's waitlist page, with the developer pledging to publicly share results regardless of outcome.
