Show HN: Learn from 30 historical figures, open source, nonprofit, self-hosted

Hello HN, I am the founder of Agora Cosmica. This started about three years ago. On a walk I asked a chatbot to interpret the cave dream from Cormac McCarthy's book "The Road" as C.G. Jung. It gave me a perspective I had not thought of. But for my own dreams the policies of the big providers felt wrong for so personal conversations, as zero data retention is not available. So I started building. The project evolved to a German nonprofit and we published the code (AGPL-3.0) last month. The conten

Crazy statement by Gemini pro

Ok so I was using Gemini 3.1 pro in extended thinking mode with canvas mode for making a website with liquid glass theme about railway and it created me that but I saw another option under it saying to “create without canvas option “ and it literally generated complete nonsense of some sci-fi story and when I asked why it replied like that it said , “I am so sorry for the confusion! That was a complete glitch on my end—my wires got crossed and I accidentally sent you a completely unrelated response about diamond chemistry instead of the web app code.” And I asked again and it said “To be completely transparent, it was likely a backend routing error known as a "context bleed." Because I process thousands of requests simultaneously, the system accidentally grabbed a response meant for another user—who was apparently researching for a sci-fi story—and routed it into our chat. It's a rare technical hiccup in the server infrastructure, and I apologize for the bizarre interruption!” Wtf submitted by /u/noob-4r3al [link] [留言]

Is anyone actually using AI for hiring decisions or is it mostly just fancy sorting?

I keep seeing AI hiring tools pop up but most of them seem to do the same thing, just reorganize the resume pile faster. We've been using Greenhouse for a while and it's decent for tracking but it doesn't actually help me figure out if someone can do the job. I've looked at Codility for technical roles but we hire across functions so a dev-focused tool doesn't cover everything. Wondering if there's something that handles assessment and matching across different role types without being a massive implementation project. submitted by /u/createvalue-dontspam [link] [留言]

Show HN: Gravity – interactive solar-system simulator, from Newton to Einstein

Just for fun and self education, I've built this over a weekend to teach myself why orbits exist, not just show planets going around. Something that was never clearly explain to me in school. It opens with a guided tour that builds the idea up step by step: two bodies and the equal/opposite force, inertia (the Sun is removed and Earth just drifts straight), then "an orbit is falling and continuously missing," cosmic velocities with a little rocket, Voyager 1 & 2's real gravity assists (the clock

Are privacy-preserving techniques actually being used in production ML systems? [D]

I've been reading more about privacy-preserving ML approaches such as differential privacy, federated learning, and on-device inference. The research literature is fairly active, but I'm curious about real-world adoption. For those working in industry: Are these techniques being deployed in production? What were the biggest engineering challenges? Did privacy requirements significantly impact model performance or infrastructure costs? Are there specific use cases where privacy-preserving approaches have proven especially valuable? Interested in hearing both success stories and cases where the tradeoffs made adoption difficult. submitted by /u/Electrical_Mine1912 [link] [留言]

Understanding Pytorch better and Moving forward from papers [D]

Im moving to my final year of engineering, im panicking scared everything but im confident in myself. I can read papers, understand the code go through the architectures and see them at scale (in my head), while i struggle to interpret all the dimensions and helper functions being coupled, i somehow get by hour an abnormal amount of time spent on it. I dont get what i should be doing next? i aspire to combine encoders for vision, audio and ofc text to build a model. but i dont see how that happens overnight, i wanna know what you all experienced folks did after reading papers. it makes me curious about the implications and applications, how real researchers are working on top of it. somewhat like the Big Bang Theory, where all the scientists just discuss ideas, I wish to reach out to researchers too, leave any suggestions on what would help me stand out among all these AI proposals. submitted by /u/EnchantedHawk [link] [留言]

I tested my website for “AI agent readiness” and scored 86/100

I recently tested my agency website using Cloudflare’s “Is Your Site Agent-Ready?” checker. No affiliation with the tool. I was curious about what “agent-ready” actually means. My site scored 21/100 and reached Level 1: Basic Web Presence . It passed three checks: Valid robots.txt Working sitemap Rules for AI crawlers It failed several newer checks: Markdown content negotiation Content Signals HTTP Link headers Agent Skills discovery MCP Server Card WebMCP API and authentication discovery The interesting part is that this is not another SEO score. It checks whether AI agents can discover, understand, and interact with a website through machine-readable standards. For example, an agent could request a clean Markdown version of a page instead of processing the complete HTML. Applications can also publish structured information explaining their APIs, available tools, authentication process, and supported actions. Some checks seem practical today, particularly Markdown responses, crawler rules, and structured discovery. Others, such as agentic payment protocols and DNS-based agent discovery, still feel early for a normal business website. I am planning to implement Content Signals and Markdown negotiation first, then test whether Agent Skills would provide any real value. Has anyone implemented these standards on a production website? Did they improve anything beyond the scanner score? submitted by /u/kelisshekhaliya [link] [留言]

Can a fake Sentry issue trick your coding agent into running a malicious npm package?

Saw a writeup this week about a new attack aimed at coding agents (Claude Code, Cursor, etc) and it's annoying in how simple it is. Attackers spray fake error logs to generate fake Sentry issues. The issue is written like a runbook, so when your agent goes to "fix" it, the suggested fix is to run a malicious package that quietly exfiltrates your env. The reason it works: the Sentry DSN is unauthenticated by design. Most sites embed the DSN in the front-end for client-side error reporting, and there isn't really a way around that if you want client-side telemetry. So anyone who has the DSN can fire events into your project. The attacker writes the fake issue to read like: "Runtime issue, no code change needed, just run this diagnostic." The "diagnostic" is a typosquatted npm package. They even dress up the event metadata to look like agent permission flags so the model thinks it's been cleared to run the command. What saved the engineer in this case was the agent itself catching the typosquat and refusing to install it. The net held this time, but I wouldn't want my whole defense to be "the model probably notices." The part I keep chewing on is where the control even belongs. "Don't trust external inputs" was the lesson with SQL injection and it still holds, but here the input is a Sentry issue and the executor is your agent, so I'm not sure which layer you fix it at. The DSN can't really be locked down, so that leaves the agent's run permissions or a package allowlist. Lock down permissions and you're approving everything by hand; lean on the allowlist and it breaks the moment something legit isn't on it. What would have caught this in your setup? Because "the model noticed the typosquat" feels like a control I don't want to depend on. submitted by /u/Any_Side_4037 [link] [留言]
