IMAGEAt the Edge of LightIn this photo taken on April 6, 2026, a portion of the Moon’s far side is seen along the terminator—the boundary between lunar day and night—where low-angle sunlight casts long shadows across the surface. A section of Orientale Basin is visible along the upper right portion of the lunar disk, its structure subtly revealed under […]

Show HN: Kontext CLI – Credential broker for AI coding agents in GoWe built the Kontext CLI because AI coding agents need access to GitHub, Stripe, databases, and dozens of other services — and right now most teams handle this by copy-pasting long-lived API keys into .env files, or the actual chat interface, whilst hoping for the best.The problem isn't just secret sprawl. It's that there's no lineage of access. You don't know which developer launched which agent, what it accessed, or whether it should have been allowed to. The moment you hand raw credentials to a process, you've lost the ability to enforce policy, audit access, or rotate without pain. The credential is the authorization, and that's fundamentally broken when autonomous agents are making hundreds of API calls per session.Kontext takes a different approach. You declare what credentials a project needs in a .env.kontext file: GITHUB_TOKEN={{kontext:github}} STRIPE_KEY={{kontext:stripe}} LINEAR_TOKEN={{kontext:linear}} Then run `kontext start --agent claude`. The CLI authenticates you via

Show HN: OpenFable – Open-source RAG engine using tree-structured indexesHi HN, I built OpenFable, an open-source retrieval engine that implements the FABLE algorithm (https://arxiv.org/abs/2601.18116) for RAG pipelines. I'm using it in another project and thought that others might benefit. Most RAG systems chunk documents into flat segments and retrieve by vector similarity. This works for simple lookups but breaks when answers span multiple sections, when relevant content is buried in a subsection, or when you need to control how many tokens you're sending to an LLM. OpenFable takes a different approach: when you ingest a document, it uses an LLM to identify discourse boundaries (not fixed-size windows), then builds a hierarchical tree, root, sections, subsections, leaf chunks, with embeddings at every level. Retrieval combines two paths: 1. LLM-guided path: the LLM reasons about which documents and subtrees are relevant from summaries 2. Vector path: similarity search with structure-aware score propagation through the tree Results from both paths are fus

IMAGEShow HN: AptSelect – A local desktop app to test LLMs side-by-sideHi HN,Whenever I needed an LLM to reliably output JSON or follow strict formatting rules, I kept having to write throwaway JavaScript scripts just to test the same prompt against OpenAI, Anthropic, and Google APIs to see who actually followed the instructions. It was a tedious workflow, so I built a local desktop UI to just do it for me.What it does:* Sends one prompt to OpenAI, Anthropic, Mistral, and Google simultaneously so you can compare the outputs in a single grid.* Automatically checkpoints your runs. If you tweak a word and the output gets worse, you can just click back to the previous version.* Exposes raw API responses, latency stats, and token usage instead of hiding them behind a chat UI.* Saves your history to a local SQLite file on your disk.* Keeps your API keys encrypted locally (zero telemetry).Yes, it is built on Electron. I sincerely apologize to your RAM. I tried to mitigate the usual bloat by sticking to vanilla JS and native Web Components, so it idles around ~24
IMAGEArtemis II mission beginsAt 00:35 CEST today (18:35 local time on 1 April), NASA's Space Launch System rocket lifted off from the Kennedy Space Center in Florida, carrying four astronauts aboard the Orion spacecraft on Artemis II. At the heart of the mission is ESA's European Service Module, which powers, propels and sustains the Orion spacecraft and its crew on their journey around the Moon and safely back to Earth.
