Show HN: OpenSymbolicAI – Agents with typed variables, not just context stuffinghttps://news.ycombinator.com/item?id=46876687Hi HN,We've spent the last year building AI agents and kept hitting the same wall: prompt engineering doesn't feel like software engineering. It feels like guessing.We built OpenSymbolicAI to turn agent development into actual programming. It is an open-source framework (MIT) that lets you build agents using typed primitives, explicit decompositions, and unit tests.THE MAIN PROBLEM: CONTEXT WINDOW ABUSEMost agent frameworks (like ReAct) force you to dump tool outputs back into the LLM's context window to decide the next step.Agent searches DB.Agent gets back 50kb of JSON.You paste that 50kb back into the prompt just to ask "What do I do next?"This is slow, expensive, and confuses the model.THE SOLUTION: DATA AS VARIABLESIn OpenSymbolicAI, the LLM generates a plan (code) that manipulates variables. The actual heavy data (search results, PDF contents, API payloads) is stored in the Python/runtime variables and is never passed through the LLM context until a specific primitive actually ne

Show HN: Localflare – Local Dev Dashboard for Cloudflare Workers(D1, KV, R2 etc.https://github.com/rohanprasadofficial/localflareI built Localflare because developing with Cloudflare Workers locally felt blind – you couldn't see what was actually in your D1 databases, KV stores, or R2 buckets during development.Just run `npx localflare` in any Workers project and get a full dashboard with:- D1 Studio: SQL editor, inline editing, filtering, dummy data generation (Faker.js) - KV Browser: View/edit key-value pairs - R2 File Manager: Upload/download objects - Queue Inspector: Send test messages - Durable Objects: View instance stateThe interesting technical bit: it uses a sidecar architecture that injects an API worker alongside yours in the same wrangler process. Both workers share the exact same binding instances – no mocks, real data. Your code stays completely untouched.Zero config. Works with any framework (Hono, Remix, Astro, OpenNext, Nuxt). Just needs wrangler.toml.Would love feedback, especially on what bindings or features you'd want next.

Laser method proposed to extend muon lifetime for science applicationshttps://www.spacedaily.com/reports/Laser_method_proposed_to_extend_muon_lifetime_for_science_applications_999.htmlLondon, UK (SPX) Jan 28, 2026 Unless they work in particle physics or a related discipline, most people are unlikely to have encountered muons, elementary particles that resemble electrons but are around 200 times heavier and interact only weakly with matter. This combination of properties enables muons to penetrate dense materials and be used in imaging techniques similar to X rays, but on the scale of large and heavy struc

The Perception War: How Artemis II Could Win the Race Without Landinghttps://www.spacedaily.com/reports/The_Perception_War_How_Artemis_II_Could_Win_the_Race_Without_Landing_999.htmlNew York NY (SPX) Jan 31, 2026 As NASA counts down toward humanity's first crewed lunar mission in more than half a century, a question beyond engineering is taking shape: Can a flight that never touches the surface still define who "wins" the Second Moon Race? The answer lies not in propulsion equations or landing dynamics, but in the realm where space programs have always competed most fiercely-perception, prestige, and the stories nations tell about themselves.

Ask HN: What's your competitive intelligence workflow as a small team?https://news.ycombinator.com/item?id=46865447I've been researching how founders track competitors and the tooling landscape is interesting. Enterprise teams use Klue/Crayon ($20K+/yr), mid-market uses Competitors.app ($15-20/competitor/mo), and everyone else seems to use... Google Alerts and hoping for the best?Curious what actually works for small teams:- Do you actively monitor competitors, or just check in occasionally? - What signals matter most? (pricing changes, feature launches, hiring, funding?) - Is the raw data useful, or do you need someone to interpret "competitor X changed their pricing page" into "here's what this means for you"?I keep hearing founders say they got blindsided on sales calls by competitors they didn't know existed. Wondering if this is a real pain point or just something people complain about but don't actually prioritize.

Show HN: Clod.ai – A Literal Wayback in Time Machine in Figuratively No Timehttp://lingocoder.com/clod.ai/I discovered a free online Pomodoro timer in 2018. [1] I'd been a frequent user of it from then until it was decommissioned in early '25. I found it super helpful for timeboxing stuff within easy-to-commit-to intervals.About a month ago, I started having really intense hunger pangs for it.A few pages of the original implementation are archived on the Wayback Machine. A couple weeks ago, I got the idea to reverse-engineer it using those pages as a reference.That's when I started researching what the Claude Code fuss was about. I wasn't then and am still not ready to spend money on AI. So, when I stumbled on the free Claud.ai, I figured I'd test it out on my reverse-engineering idea.I used Copilot, Sourcegraph's Cody Visual Studio Code agent and ChatGPT a decent amount last year. More recently I've been using Gemini Code Assist. But this project was my first time ever using Claud.ai.I guess Claude.ai in the browser uses React and Tailwind CSS for building web apps.

I spent 1 year building my SaaS and only then realized I built the wrong thinghttps://news.ycombinator.com/item?id=46862046I just shipped my first SaaS.Not “failed”. Not “crushed it”. Just… shipped it.And here’s the brutal summary I wish someone had slapped me with on day one:Build the MVP — and for the love of god, stop there. Then immediately switch your brain to distribution.I spent almost a full year polishing features, refactoring code, improving edge cases that no user ever asked for. I told myself I was being “serious” and “professional”.Reality check: I was procrastinating on marketing.Only now do I realize how backwards my thinking was. You don’t earn the right to market after building something perfect. Marketing is part of building the product.Some other things I learned the hard way:• Almost every idea is good if it solves a real pain. Execution and distribution matter more than originality. • “Find your audience” is good advice — but it’s much easier when you’re early or niche. If you’re not first, you need a sharper angle, not a bigger product. • Silence is the worst feedback. No hate, no lov

Scientific data about this atmospheric reentry process is urgently needed to design future satellites for a quick, safe and sustainable demise at the end of their mission – reducing risks on the ground and in space.

Starlink terminals, which were discreetly mounted on rooftops, helped Iranian protesters bypass this internet blackout.

Show HN: I turned my PDFs into audiobooks I can have conversations withhttps://asktotle.comHey HN,TLDR: Upload any document, get an audiobook with synced highlighting you can pause and talk to.I'm a self-taught dev (admittedly mediocre), currently between jobs and my brain is absolutely fried from social media. I can't read anymore. My eyes glaze over after two paragraphs.So I went down a rabbit hole looking for scientifically proven ways to actually focus while reading:- Encoding info visually AND aurally reduces mind wandering by up to 40% - Retrieval practice (asking questions) beats passive re-reading every time - Background music matched to content keeps you in flowCouldn't find anything that did all this. So I built it myself:- Synced text highlighting while you listen - Talk with your book; pause and ask "wait what does that mean?" and it knows exactly where you are (won't spoil what's ahead) - Adaptive background music that matches the mood of each pageI've removed all slop. No flashy features, no gamification etc. etc. Just reading on steroids for fried brains, like
