Show HN: Big Christmas Giveawayhttps://indest.ee/Hi everyone,Last giveaway of the year!I wanted to wrap up 2025 by giving back to the community. It’s been a busy year for me as a solo developer; I managed to release two brand new titles and finally finished a massive consolidation update for my puzzle series.If you are looking for something new to play over the holidays, I’d love to share some promo codes. Just let me know which game interests you!The New 2025 Releases:Trivia Player: This is for the hardcore trivia fans. I built this because I was tired of multiple-choice quizzes that hold your hand. This is authentic trivia—real-time chat battles where you have to actually type the answer. No luck, just pure knowledge.Live Events: The game is live right now with a special "Merry Quizmas" event running all week. Also, mark your calendars for "Do You Remember 2025" starting on the 26th!AI Movie Quiz: I used AI to generate unique, slightly twisted clips and images based on famous movies. You have to guess the film from the AI's "dream.Dec 20, 2025 3:00 PM

The offline geocoder we wantedhttps://news.ycombinator.com/item?id=46334172What is this?This is an offline reverse geocoder written in Python. Given a latitude–longitude pair, it returns the correct administrative region such as country, state, or district without calling any external APIs. This avoids API costs, rate limits, and network dependency.Why build another reverse geocoder?Most offline reverse geocoders rely on nearest-neighbor lookups. While fast, this approach often fails near borders because the closest location is not always the correct administrative region. This project focuses on correctness over proximity by verifying which boundary a coordinate actually falls inside.How does it work?A KD-Tree is used to quickly shortlist nearby administrative boundaries. For those candidates, the system performs polygon containment checks to confirm the true region. It supports both single-process execution for small workloads and multiprocessing for large batch processing.PerformanceThe system processes 10,000 coordinates in under 2 seconds, with an averagDec 20, 2025 7:03 AM

MyRobot, a Venture Capital Pitchhttps://news.ycombinator.com/item?id=46333852Wrap yourself in a personal robot called Ava (homage to Ex Machina).A perfect morning coffee is waiting as you wake up. The house robot brings it to you as you awake.Suppose you want to get breakfast at a restaurant. The car shows up. You get driven to the restaurant. As you get seated your order arrives. Ava knows that you like an omlette, lightly cooked, with ham and bacon. You like your homefries crisp. You like a small orange juice. It is all ready for you moments after you walk in the door because Ava told the restaurant what you want and when you will arrive.Ava also knows that you want to keep your weight at a certain number. She tracks your calorie intake and creates food proportions and choice to meet your calerie requirements, tuned to the day's activities based on likely calorie burn.Ava reads books to you through the embedded speaker in your ear, tuning your book choice to the day.

Geometric derivation of the muon g-2 anomaly (63 ppm discrepancy)https://news.ycombinator.com/item?id=46327402The Standard Model calculation of g-2 requires thousands of Feynman diagrams. This geometric model derives it from the topology of the lepton (icosahedron, 12 vertices). It posits the muon anomaly is the sum of the surface cost (Schwinger term) and the nodal friction against the 12 vertices: α = 0.00729735256 N_v = 12 Schwinger_term = α / (2 · π) Nodal_term = α^2 / 12 a_mu = Schwinger_term + Nodal_term Schwinger_term = α / (2 · π) ≈ 0.001161409 Nodal_term = α^2 / 12 ≈ 0.000004438 Total ≈ 0.001165847 Experimental value: 0.001165920 Discrepancy: 63 ppm Source: Geometric Unification of Physical Interactions, v10. https://doi.org/10.5281/zenodo.17847770Dec 19, 2025 4:14 PM

I built a tool to stop wasting hours on LinkedIn outreach messageshttps://news.ycombinator.com/item?id=46322924I've been doing cold outreach on LinkedIn for two years. Not at scale — maybe 10-15 messages a day to potential customers.The problem was never finding people to message. LinkedIn search works fine. Sales Navigator exists. Referrals happen.The problem was opening their profile and... staring."Okay, they're a VP of Engineering at a Series B company. They posted about technical debt last week. How do I not sound like every other person in their inbox?"Delete. Rewrite. Check if it's too long. Too short. Too salesy. Not specific enough.Forty-seven minutes later, I'd written four messages.The real issueMost outreach tools solve the wrong problem. They give you:Templates with merge tags ({{firstName}} works at {{company}}) Auto-send features that violate LinkedIn's ToS Bulk sequence automationBut that's not where I was stuck.

It includes CI-driven stress tests, a certification badge, and reproducible benchmarks. Repo + quickstart: https://github.com/CULPRITCHAOS/InterlockWhat it doesTracks AI confidence, hazards, and triggers a reflex (refuse/degrade) rather than silently returning incorrect answers. Produces tamper-evident audit trails (HMAC-SHA256 signed badges, incident logs, validation artifacts). Ships middleware for Express and FastAPI; adapters for 6 vector DBs (Pinecone, FAISS, Weaviate, Milvus, LlamaIndex, LangChain). CI workflows to test, stress, benchmark, and auto-generate certification badges. Evidence artifacts are preserved and linkable. Why it mattersMany systems log “success” when an LLM confidently hallucinates. Audit trails and refusal policies matter for safety, comDec 19, 2025 3:16 AM
