In fact, there are no known sources anywhere in the universe capable of producing such energy - 100,000 times more than the highest-energy particle ever produced by the Large Hadron Collider, the world's most powerful particle accelerator.

Show HN: A 3D chessboard sandbox with optional WebGPU path tracinghttps://chessboard3d.app/I wanted to explore GPU ray tracing, so I built a free chess board that feels like playing at a café in real life.The goal was over-the-board (OTB) realism. It’s a physics-based sandbox where you manually drag pieces, move the rook for castling, and clear captured pieces yourself. You can even knock them over. The original idea came from my friend, Drew Olbrich (lunarskydiving.com), who built an SGI-based version of this concept at PDI in the '90s.I spent three decades writing rendering code at PDI/DreamWorks and NVIDIA. I wrote the rendering pipeline from scratch in WebGPU. It defaults to an optimized rasterized "fast path" but if you have a good GPU, you can enable a real-time path tracer in the settings. I implemented this using a 4-layer depth-peeled G-Buffer and Hierarchical Z-Buffer DDA for ray marching, supporting multi-bounce GI and environment map importance sampling.The scene is lit entirely by a single HDRI environment map, with no local light sources.

Show HN: WarpParse – Rust ETL engine 1.5–8x faster than Vectorhttps://news.ycombinator.com/item?id=46880903Hey HN, We’ve been working on WarpParse, an open-source (Apache 2.0) ETL engine built in Rust, and we’re excited to share it with you today. We built it because we found that existing tools often struggled with resource efficiency or configuration complexity when handling massive log volumes. WarpParse aims to solve this with: Performance: 1.5x to 8x higher throughput than Vector in our benchmarks. Efficiency: Uses ~1/3 the CPU and ~37% of the memory of Vector under similar loads. DSLs: We created WPL (Warp Parse Language) for strong-typed parsing and OML (Object Modeling Language) for declarative data enrichment with native SQL integration. We’ve also built a visual editor (WpEditor) to make rule-writing less of a headache. We’d love to hear your thoughts on the architecture, the DSL approach, or any feedback you have after checking out the repo.

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 neFeb 3, 2026 8:19 PM

Show HN: Clawdstrike – a security toolbox for the OpenClaw ecosystemhttps://github.com/backbay-labs/clawdstrikeHi HN.OpenClaw has been popping claw for weeks now…We’ve seen the same question come up again and again: “This is fun but how do we no get fuk?”My answer: Clawdstrike.It’s an open-source toolbox for developers who want to ship EDR-style apps and security infrastructure to the OpenClaw ecosystem.Disclaimer: this is an unpublished alpha (APIs will change). Beta is planned within ~7 days (aiming for Feb 10, 2026). Not audited—please treat as experimental.Here’s my take: the first wave of “make autonomous agents safe where users are literally yoloing their entire system without even watching” is actually pretty simple.Security needs to live at the boundary between an agent’s intent and action — the moment it tries to read/write files, patch code, call tools, or reach the network.Not just “visibility.” Not just logs. But enforcement + proof.What Clawdstrike gives you: - Fail-closed guards at the agent/tool boundary - Block sensitive paths, control network egress, detect secrets, validate paFeb 3, 2026 7:19 PM

Show HN: C discrete event SIM w stackful coroutines runs 45x faster than SimPyhttps://github.com/ambonvik/cimbaHi all,I have built Cimba, a multithreaded discrete event simulation library in C.Cimba uses POSIX pthread multithreading for parallel execution of multiple simulation trials, while coroutines provide concurrency inside each simulated trial universe. The simulated processes are based on asymmetric stackful coroutines with the context switching hand-coded in assembly.The stackful coroutines make it natural to express agentic behavior by conceptually placing oneself "inside" that process and describing what it does. A process can run in an infinite loop or just act as a one-shot customer passing through the system, yielding and resuming execution from any level of its call stack, acting both as an active agent and a passive object as needed. This is inspired by my own experience programming in Simula67, many moons ago, where I found the coroutines more important than the deservedly famous object-orientation.Cimba turned out to run really fast.

My folders are full of files like final_v2_edit.docx and draft_2024_backup.pdf. Tools like Everything are great if I remember the filename, but I usually only remember the concept of what was inside.The Tech & Privacy: Folion indexes your folders locally using a vector store on your machine. I’ve added a RAG-based search engine that operates locally and an LLM layer via AWS Bedrock so you can chat with your files. Your index and embeddings never leave your device; only the specific snippets retrieved for a query are sent to the LLM for response generation.Quick 30-second trailer: https://www.youtube.com/watch?v=94puRu4GMKg (Full 14-min demo on the website).Being Realistic About Limitations: Since this is a solo project, I want to be upfront about what it is and isn't:It’s a Precision Tool: For Feb 3, 2026 3:17 PM
