Show HN: Everest Drive – a multiplayer spaceship crew simulator in the browser Hi HN! I'm working on an open-world multiplayer space sim with submarine-warfare-inspired combat. Crew a ship, haul cargo, run heists, hunt your foes with passive and active sensors. Browser-based, free, no install. Some of its features: - Submarine-style passive sensors. Contacts start as a bearing line (direction, no distance), resolve into an uncertainty circle, then into a full track. You triangulate over time by moving. - Silent running. Cut your emissions and witnesses can't ID you. - Newtonian flight. No drag, no auto-brake. Flip 180° and burn to stop. - Boarding combat. Dock with another ship and fight through it room by room. Architecture: - The server is a single Rust module compiled to WASM, running inside SpacetimeDB. - Clients subscribe to rows in the schema and get live deltas over websocket; writes go through reducers (transactional Rust functions). No REST, no custom netcode, no client-side authority. - Client is Svelte 5 + plain HTML5 canvas 2D. No game engine, no WebGL. https://ift.tt/fR6dMvC Very early, plenty of rough edges. Would love to hear what breaks for you: https://everestdrive.io https://ift.tt/ejFbURM April 22, 2026 at 11:27PM

Show HN: Almanac MCP, turn Claude Code into a Deep Research agent https://ift.tt/wIOJZaA

Show HN: Almanac MCP, turn Claude Code into a Deep Research agent I am Rohan, and I have grown really frustrated with CC's search and read tools. They use Haiku to summarise all the search results, so it is really slow and often ends up being very lossy. I built this MCP that you can install into your coding agents so they can actually access the web properly. Right now it can: - search the general web - search Reddit - read and scrape basically any webpage Install it: npx openalmanac setup The MCP is completely free to use. We have also built a central store where you can contribute things you learned while exploring. If you find something useful, you can contribute it to the encyclopedia we're building at Almanac using the same MCP. https://ift.tt/eBynXQ9 April 22, 2026 at 03:42AM

Show HN: Backlit Keyboard API for Python https://ift.tt/2o3ZVp4

Show HN: Backlit Keyboard API for Python It currently supports Linux as of now. You can use this package to tinker with many things. Let's say, if you want to make a custom notification system, like if your website is down, you can make a blink notification with it. MacOS support is underway. I haven't tested Windows yet, I don't use it anymore btw. In future, if this package reaches nice growth, I'll be happy to make a similar Rust crate for it. https://ift.tt/BmaRMrv April 19, 2026 at 12:22PM

Show HN: Git Push No-Mistakes https://ift.tt/G9QHrVE

Show HN: Git Push No-Mistakes no-mistakes is how I kill AI slop. It puts a local git proxy in front of my real remote. I push to no-mistakes instead of origin, and it spins up a disposable worktree, runs my coding agent as a validation pipeline, forwards upstream only after every check passes, opens a clean PR automatically, and babysits CI pipeline for me. https://ift.tt/iGrE7sV April 21, 2026 at 12:10AM
