Show HN: Inception: Automatic Rust Trait Implementation by Induction https://bit.ly/4m5UqZP

Show HN: Inception: Automatic Rust Trait Implementation by Induction Hi HN, I thought this would be a good place to share a little puzzle I've been working on. Inception is a Rust library that helps you share behaviors in Rust using structural induction. Practically, this means that instead of having a derive macro for each behavior, a single derive can be used to enable any number of behaviors. It doesn't do this using runtime reflection, but rather type-level programming - so there is monomorphization across the substructures, and (at least in theory) no greater overhead than with macro expansion. While there are a lot of things missing still and the current implementation is very suboptimal, I'd say it proves the general concept for common structures. Examples of Clone/Eq/Hash/etc replicas implemented in this way are provided. The code is not idiomatic, which is my biggest reservation about continuing this work. It was fun to prove, but is not so fun to _improve_, as it feels a bit like swimming upstream. In any case I hope some of you find it interesting! https://bit.ly/4gaLgda September 6, 2025 at 05:01AM

Show HN: CompareGPT – Spotting Hallucinations by Comparing Multiple LLMs Hi HN I’m Tina. One frustration I keep running into with LLMs is hallucinations: answers that sound confident but are fabricated. Fake citations, wrong numbers, even entire “system reports.” So I’ve been building CompareGPT, which tries to make AI outputs more trustworthy by: Putting multiple LLMs side by side for the same query Making it easy to see consistency (or lack of it) Helping catch hallucinations before they waste time or cause harm link here： https://bit.ly/3I8Br2Y . We’ve opened a waitlist and would love feedback, especially from folks working with LLMs in research, finance, or law. Thanks! September 6, 2025 at 12:26AM

Show HN: A credibility-based social platform (no Likes) to fight misinformation https://bit.ly/4lYibDa

Show HN: A credibility-based social platform (no Likes) to fight misinformation Most people now get their news from social feeds — but those feeds reward popularity, not accuracy. Misinformation spreads fast, and even well-intentioned users often can’t tell what’s reliable. I’ve been working on a different approach: a social/news platform where every post carries a credibility score. Instead of likes or shares, users assess posts by linking to supporting or refuting sources. Credibility then updates across posts, users, and domains in real time. A few things that might interest HN: - Anonymous/pseudonymous accounts (no personal brands driving popularity). - Credibility > virality: feeds are sorted by time & trustworthiness, not engagement. - URL and domain-level scoring: credibility of sources builds over time. - Four feeds: Front Page, Bullpen, Cred Desk, and Subscriptions (you can filter by credibility percentile). It’s in public beta here: https://bit.ly/3K61sjX Curious what HN thinks: - How might this system be gamed or abused? - What are your thoughts on pseudonymous usernames? - What would make it more useful for people who actually want reliable news? https://bit.ly/3K61sjX September 5, 2025 at 03:32AM

And if you have experiences building telecommunication infra or happen to be wanting the same thing I'd love a chat.

Show HN: TwoTickets – meet through events, not swipes https://bit.ly/4neBut5

Show HN: TwoTickets – meet through events, not swipes The idea for TwoTickets started when my wife and I had two tickets to Hamilton, and she couldn’t make it at the last minute. I realized how awkward it is to want to go to a concert, game, or show but not have someone to share it with — and how current apps either constrain you to your circle or to endless swiping. On TwoTickets, you Twoot an event in order to connect with others around that shared plan. The flow is simple: Twoot → Match → Chat → Decide → Go. You don’t see profiles or matches until you Twoot events, so plans come first and profiles second. The aim is to make meeting new people more natural: the event itself is the ice-breaker, not a random line in a bio. We’re in soft launch now and would love feedback from HN — does this “event-first” approach resonate with you, and where do you see the pitfalls? Paul Graham once said that all dating apps are really just matching apps. I wonder: how close is this to a solution to that assertion — although TwoTickets is broader than dating. *Links:* - Website: https://bit.ly/3I2UR9s - iOS App: https://apple.co/4p6OCSE...

Show HN: slack-explorer-mcp – Let AI find historical context in Slack I built an MCP server that lets AI tools search Slack history to answer “why did we do X?” It reads messages and threads with your Slack user token, so agents like Claude Code/Desktop, VS Code and Cursor can pull context that isn’t in code or PRs. Features: * Search by channel, user, date range, reactions, has:file, etc. * Get full thread replies. * Look up users by ID or display name. Example uses: * “Why is foo_summary BigQuery table a materialized view?” * “Summarize this week’s topics in #random.” More details in the blog post: https://bit.ly/47kc6gN... https://bit.ly/3HTPhX2 September 3, 2025 at 12:14AM

Show HN: AfriTales – Discover the Magic of African Storytelling https://bit.ly/4p1J6kj

Show HN: AfriTales – Discover the Magic of African Storytelling Hi HN, I've been working on AfriTales, a flutter based mobile app that brings African folktales into modern stories narrated episodes wrapped in a children and adult friendly UI player. The stories are created to cover north, south, west and east Africa. I think of it as a digital by-the-fire-side. Why AfriTales: Cultural relevance: There is a gap in culturally-rich audio-native storytelling apps for Africans, the diaspora and people interested in African stories. Modern Influence: Modern UI makes the the app feel elegant and emotionally resonant. Retention via structure: Episodes are short (2-5 minutes) and there are stories series for premium users. MVP features include: A launch landing page ( https://bit.ly/3Vq6t9x ) for early engagement and waitlist signups. I have currently sourced over 100 stories. Thanks to Google's Gemma 3 270M, users can generate stories with their own twist. Freemium model: 3 free tales per day, plus premium subscription for unlimited access. Robust Flutter structure: Architecture with TTS integration, and images for context. I am starting in Ghana before expanding, and I'd love feedback from this community: Would you (or your child) use an audio-based storytelling app with a strong regional cultural tie? Suggestions for retention strategies or content formats that engage long-term users? Thanks https://bit.ly/3Vq6t9x September 1, 2025 at 12:53PM
