Show HN: Swik – catalog of asset-specific sentiment inversions for financial NLPhttps://news.ycombinator.com/item?id=47436845tried to do financial sentiment analysis but kept hitting the same wall with FinBERT: "OPEC cuts production" scores negative. For crude oil it should be bullish — less supply means higher prices. Generic models don't know what phrases mean for a specific asset.No existing dataset captured this systematically. Every financial sentiment project I found was either abandoned or producing generic polarity that was actively wrong for commodities and FX.So I built swik — at first for myself, then I kept finding zero alternatives and thought this could interest other people. Many sentiment analysis projects out there are abandoned for this very reason: failure to produce meaningful, correct and reliable sentiment for a given asset-specific headline.Then I thought: "build it and they will come." Now there it is — an open, community-maintained catalog of phrase inversions for 35+ assets (commodities, FX, indices, crypto). Each entry has the phrase, naive polarity, actual direction for that assetMar 19, 2026 9:34 AM

Show HN: Play against a live RL agent in a pixel platformerhttps://rlplays.com/gameI trained a live RL agent inside a pixel platformer you can play against on a desktop browser (needs a keyboard or a controller):https://rlplays.com/gameThis is NOT a quick-one-off vibe/LLM-coded project.I started this project out of curiosity: I wanted to build an RL-based game as there were very few out there (e.g. Sony GT Sophy). And I wanted to learn the core RL foundation in a practical/useful manner.I built on top of Puffer - but the training speed was not up to my needs so I rewrote the core with a ground-up native eval/training loop with multithreaded GPU batching (gonna be a part of the next Puffer release). [ Unaffiliated plug: Puffer is an excellent OSS library - check out https://puffer.ai ]I trained the RL agent using curriculum learning + self-play. The demo showcases this self-play as well - which you can play against yourself, like an RL agent would!Technical details in my blog in the link above.Mar 19, 2026 8:09 AM

Ask HN: How are you protecting yourself from skill atrophy?https://news.ycombinator.com/item?id=47430736I’m interested in how people working in tech are avoiding skill atrophy in this LLM age?We’ve all seen both sides of the argument spectrum, with “Let them atrophy, LLMs are the future, just look at the abacus!” to “I don’t use LLMs, they make mistakes and get in the way”. But the reality for many is that LLMs give a real performance boost and take on many tasks, even if they do make mistakes and need babysitting.I fall on the side of caution in letting skills fall behind, there are too many unknowns in how much LLMs will drive workplaces in the medium to long term and what skills will be used, so I’m wondering how you keep your existing skills from atrophying when tempted with the “make it so” button?Mar 18, 2026 8:03 PM

MCP servers mass-forked and republished – supply-chain attack vectorhttps://news.ycombinator.com/item?id=47428217I'm the developer of an MCP server (AiDex — code indexing with Tree-sitter, github.com/CSCSoftware/AiDex). I recently discovered that an organization called iflow-mcp is systematically forking hundreds of MCP servers on GitHub, republishing them under their own npm scope (@iflow-mcp/) and on PyPI, and distributing them through their own "marketplace" — without ever contacting the original authors.But the real problem isn't the fork itself. The real problem is security.---*What's happening*The forks are published under the pattern @iflow-mcp/originalauthor-projectname. The familiar name of the original creates trust — but the code the user actually gets is entirely under a third party's control. Nothing prevents that third party from modifying the code before publishing.*Why MCP servers are particularly dangerous*An MCP server is not a harmless plugin. By design, it has deep access:- It reads your source code, navigates your filesystem, receives file contents - It can see .env files, APMar 18, 2026 4:58 PM

Show HN: I built a game where domain experts try to break frontier AIhttps://www.rusmarterthananllm.com/I built this: rusmarterthananllm.comDomain experts, doctors, lawyers, engineers, submit questions from their field that probe where frontier AI actually fails. Claude, GPT, and Gemini all attempt simultaneously. Experts flag errors with professional reasoning. Other credentialed professionals in the same domain verify them.AI benchmark performance has decoupled from real-world professional capability. Models score at or near ceiling on standard evaluations while still failing in ways that domain professionals catch immediately. The benchmarks that exist are either saturated, constructed by the labs themselves, or simply don't capture the judgment that comes from years of field experience.What's missing is a benchmark built by the people whose expertise is actually at stake. Professionals motivated to find failures, not validate models. Every verified failure becomes a permanent data point.

Show HN: unTamper – cryptographically verifiable audit logs for app eventshttps://news.ycombinator.com/item?id=47427580https://untamper.comBuilt this after hitting the same gap on multiple projects: teams log critical events (admin actions, permission changes, PII access) but have no structural way to prove those records weren't altered after the fact.Immutable storage (S3 Object Lock, WORM) are common, but it only covers tampering after the write lands. It doesn't protect against someone with DB write access, and it doesn't give a third party, e.g. an auditor, a way to verify integrity without touching your infrastructure.My approach: hash chaining. Each event is SHA-256 hashed against its canonical payload + the hash of the previous event. Any insertion, deletion, or modification breaks all subsequent hashes. Anyone with the public API can re-verify the chain independently.A few decisions I'm happy to discuss:- Canonicalization before hashing: JSON isn't canonical by default. Ended up writing a strict sorted-key schema rather than fighting recursive serialization. - Per-actor chains vs. one global chMar 18, 2026 4:13 PM

Show HN: BendClaw – Distributed AgentOS Written in Rusthttps://github.com/EvotAI/bendclawHi HN, we're open-sourcing BendClaw today -- the distributed AgentOS behind Evot.AI.The problem: one shared agent maxes out fast. Separate agents per person means everyone starts from zero. We wanted the third option -- distributed compute with shared knowledge.BendClaw is a runtime where multiple agents run in parallel, each on its own node, but all connected to one shared data layer. When one agent learns something, every other agent has it on the next run. No prompt engineering, no manual handoff.What's inside:- *Shared memory* -- all agents read and write to the same knowledge base. Context, learnings, history, fully connected. - *Cluster dispatch* -- agents fan out subtasks across nodes and collect results. Local and cloud nodes in one cluster. - *Self-evolving* -- every run automatically extracts knowledge and injects it into future runs. - *Trace and audit* -- every operation recorded. Who did what, which tools fired, what came back. All queryable. - *Secret-safe* -- secrets vauMar 18, 2026 4:01 PM

Show HN: iPhone-gated local actions on Machttps://news.ycombinator.com/item?id=47426908I built a Mac + iPhone system where the iPhone acts as a live trust key for selected processes on the Mac. How it works: - Mac and iPhone pair with mutual TLS - when the iPhone app is open, it establishes a trusted session - the Mac maintains that session with BLE presence + recurring trust proofs - if trust ends, the Mac kills the gated process Important constraint: on iPhone, this currently works only while the app is in the foreground. If the app is backgrounded, the phone is locked, or the app is closed, trust ends. In practice that means the usable trust window is short, roughly 15 to 60 seconds as no one would keep phone unlocked for too long. So the original idea of long-running DevOps sessions like SSH tunnels / kubectl port-forward probably does not hold up under this constraint. What may still fit: - decrypting a file for a brief operation - running a one-shot privileged script - briefly exposing a local signing daemon - short-lived key-use or signing actions.

Files never leave your machine.Compress, convert, trim, crop, resize, merge, rotate, reverse, speed change, screenshot, mute, video-to-GIF, audio extract/trim/convert/merge/speed, and media info.The interesting technical problem: FFmpeg compiled to WASM works, but it tops out around 4 GB, runs single-threaded, and is 10x slower than native browser APIs for the same operations. I wanted to handle 50 GB files and actually use the hardware (theoretically there's no limit at all).So I built a hybrid engine:- Most tools use WebCodecs (via MediaBunny) — the browser's native hardware-accelerated video encoder/decoder. H.264, HEVC, VP9, AV1 with GPU acceleration when available. This is what makes it fast. - Three tools (speed, merge, video-to-GIF) still use FFmpeg WASM where WebCodecs can't do the job. - The engine auto-detects which path to use and falls back gracefully — if harMar 18, 2026 3:18 PM
