Show HN: Mozilla.ai introduces Clawbolt, an AI Assistant for the tradesHey everyone, Nathan here: I'm an MLE at Mozilla.ai. I can't tell you how many things around my house I've been saying "I would really like to have somebody take a look at that". But here's the problem: all the people in the trades are extremely overwhelmed with work. There is a lot to be done and not enough people to do it.One of my best friends runs his own general contracting business. He's extremely talented and wants to spend his time working on drywall, building staircases, and listening to Mumford and Sons while throwing paint onto a ceiling. But you know what gets in the way of that wonderful lifestyle that all us software engineers dream about?ADMINISTRATION.He thought running his own business would be 85% show up and do the work, but turns out a large chunk of the time is spent talking to clients to schedule time to get an estimate, working with home management companies to explain the details of an invoice, and generally just manage all of the information that he's gathering

Show HN: AI gaming copilot that uses a phone camera instead of screen captureBuilt this as a side project after wanting a real-time gaming companion that could call out macro mistakes / timers / map awareness while I play.*Project Aegis* is an AI gaming companion (starting with League of Legends) that gives spoken advice in real time.The twist: it uses a *physically air-gapped setup*.Why? Some games (especially with strict anti-cheat like Riot Vanguard) make screen capture / memory-reading approaches risky or impractical. So instead of reading the game directly, I point a *smartphone on a tripod at my monitor* and process the video externally.*How it works (current version):** Phone camera points at the game screen * Frames are streamed over WebSockets to a local FastAPI server * OpenCV cleans up glare / perspective issues * Vision model analyzes the frame context * TTS speaks back advice (macro reminders, timers, awareness prompts, etc.)So far this is more of a *working prototype + architecture experiment* than a polished product, but it’s functional and surpr
Show HN: Lysium – cross-platform control plane for agentic software deliveryIMAGE

Show HN: Lysium – cross-platform control plane for agentic software deliveryHi HN — I built Lysium to reduce context-switching when working through GitHub issue/PR queues.Lysium uses GitHub + the Devin API so you can route work to background agents and keep moving. You can: • Swipe issues/PRs to close, merge, or skip • Launch implementation requests from issues/PRs or from a freeform Code tab • Run multiple agent sessions in parallel across repositories • Trigger one-click issue/PR assessments and PR reviews • Track progress in an Activity view split into Sessions and Actions Try it: https://www.lysium.ai/ Code: https://github.com/dabit3/lysiumNo email signup flow; full functionality requires GitHub OAuth plus a Devin API key + org ID.I’d especially appreciate feedback on onboarding friction, general UX, and where agent automation should be explicit vs automatic.

Hardware is no longer the problem holding back space-based data centers — the supply chain isOrbital and lunar data centers are often framed as engineering challenges or launch economics problems. Those matter, but they are not the limiting factor. The real bottleneck is the absence of a procurement and logistics architecture capable of sourcing, qualifying, transporting, assembling and sustaining the technologies these systems require. If companies are going to realize […] The post Hardware is no longer the problem holding back space-based data centers — the supply chain is appeared first on SpaceNews.

Show HN: Market Digest: Self-hosted market analysis and TelegramHi HN, I built this because my pre-market routine was eating 45+ minutes every morning — checking TradingView, Finviz, economic calendars, news sites, fear/greed indexes, all before market open.*What it does:* Market Digest pulls data from 6 free sources (yfinance, TwelveData, Finnhub, FRED, NewsAPI, Fear & Greed), runs multi-timeframe technical analysis (daily/weekly/monthly RSI, pivot points, trend detection), scores every instrument from 0-100, and sends you a formatted digest on Telegram.*What makes it different:* - Fully self-hosted, MIT licensed, no subscription - 84 instruments pre-configured (stocks, forex, commodities, crypto, indices) add more as you need - Multi-timeframe scoring — day trade, swing, and long-term grades with separate weight configs - Retrace system — snapshots every pick and grades it against actual next-day prices, so you see your accuracy over time - Equity fundamentals scoring (valuation, profitability, growth, health) - Custom data sources — plug in any
Show HN: Tswap–Yubikey-backed secret injection for IaC and AI-assisted workflowsIMAGE

Show HN: Tswap–Yubikey-backed secret injection for IaC and AI-assisted workflowsI built tswap after noticing that Claude Code, while genuinely useful for managing a Kubernetes cluster, was pulling plaintext secrets from every manifest it touched. I wanted the AI to be able to do its job without ever seeing the actual values.tswap keeps secrets in an AES-encrypted vault file on disk. The decryption key is derived from a YubiKey via HMAC challenge-response. At init you pair two YubiKeys — either unlocks the vault, so you have no single point of hardware failure.Config files use a comment-based placeholder that keeps them valid YAML: stringData: DB_PASSWORD: # tswap: db-password Deployment is a pipe: tswap apply values.yaml | helm upgrade myapp ./chart -f - The privilege split is the key design decision: `apply`, `run`, and `check` need no elevation (AI agent gets these). `get`, `list`, `delete`, and `export` require sudo/admin (human gets these). The AI can deploy; it can't read or enumerate secrets.Other features: burn tracking for rotation, `redact` for stripping

The future of astronomy is both on Earth and in spaceA recent SpaceNews opinion article argued that it is time to “take astronomy off Earth.” The suggestion is straightforward: If satellite constellations and commercial space activity threaten ground-based astronomy, perhaps astronomers should simply move their work into space. As current, incoming and past presidents of the American Astronomical Society, we feel impelled to respond. As […] The post The future of astronomy is both on Earth and in space appeared first on SpaceNews.

Rare lensed supernova offers new route to measure cosmic expansionLondon (SDX) Feb 25, 2026 That the universe is expanding has been known for almost a century, but its exact rate of expansion remains one of cosmology's most hotly debated questions. A team from the Technical University of Munich (TUM), Ludwig Maximilians University (LMU) and the Max Planck Institutes for Astrophysics (MPA) and for Extraterrestrial Physics (MPE) has now imaged and modelled an exceptionally rare supernova
