Show HN: RFC Hub https://ift.tt/FCtnL7e

Show HN: RFC Hub I've worked at several companies during the past two decades and I kept encountering the same issues with internal technical proposals: - Authors would change a spec after I started writing code - It's hard to find what proposals would benefit from my review - It's hard to find the right person to review my proposals - It's not always obvious if a proposal has reached consensus (e.g. buried comments) - I'm not notified if a proposal I approved is now ready to be worked on And that's just scratching the surface. The most popular solutions (like Notion or Google Drive + Docs) mostly lack semantics. For example it's easy as a human to see a table in a document with rows representing reviewers and a checkbox representing review acceptance but it's hard to formally extract meaning and prevent a document from "being published" when criteria isn't met. RFC Hub aims to solve these issues by building an easy to use interface around all the metadata associated with technical proposals instead of containing it textually within the document itself. The project is still under heavy development as I work on it most nights and weekends. The next big feature I'm planning is proposal templates and the ability to refer to documents as something other than RFCs (Request for Comments). E.g. a company might have a UIRFC for GUI work (User Interface RFCs), a DBADR (Database Architecture Decision Record), etc. And while there's a built-in notification system I'm still working on a Slack integration. Auth works by sending tokens via email but of course RFC Hub needs Google auth. Please let me know what you think! https://rfchub.app/ December 1, 2025 at 10:34PM

Show HN: An AI zettelkasten that extracts ideas from articles, videos, and PDFs https://ift.tt/Vad0z3l

Show HN: An AI zettelkasten that extracts ideas from articles, videos, and PDFs Hey HN! Over the weekend (leaning heavily on Opus 4.5) I wrote Jargon - an AI-managed zettelkasten that reads articles, papers, and YouTube videos, extracts the key ideas, and automatically links related concepts together. Demo video: https://youtu.be/W7ejMqZ6EUQ Repo: https://ift.tt/urXmGYC You can paste an article, PDF link, or YouTube video to parse, or ask questions directly and it'll find its own content. Sources get summarized, broken into insight cards, and embedded for semantic search. Similar ideas automatically cluster together. Each insight can spawn research threads - questions that trigger web searches to pull in related content, which flows through the same pipeline. You can explore the graph of linked ideas directly, or ask questions and it'll RAG over your whole library plus fresh web results. Jargon uses Rails + Hotwire with Falcon for async processing, pgvector for embeddings, Exa for neural web search, crawl4ai as a fallback scraper, and pdftotext for academic papers. https://ift.tt/urXmGYC December 1, 2025 at 11:50PM

Show HN: I Built Tinyfocus – A Minimal Tool to Help Solo Founders Focus https://ift.tt/rY0qp5l

Show HN: I Built Tinyfocus – A Minimal Tool to Help Solo Founders Focus Hi HN, I just launched Tinyfocus, a small productivity tool designed specifically for solo founders and builders. The goal is simple: help you focus on what matters and get more done in less time. Here’s what Tinyfocus does: Lets you track your top tasks and prioritize efficiently. Provides micro dashboards to keep your daily focus in check. Lightweight, no distractions, no fluff. I built it entirely by myself, iterating in public, and I wanted to share it with the community to get feedback. It’s been crazy seeing how a simple tool can make such a difference in daily focus, especially when you’re juggling multiple projects as a solo founder. Check it out here: tinyfoc.us I’d love to hear your thoughts – any feedback, feature ideas, or bugs you notice. Thanks! https://ift.tt/EWjfJOt November 30, 2025 at 11:35PM

Show HN: Nano PDF – A CLI Tool to Edit PDFs with Gemini's Nano Banana https://ift.tt/vRheFbs

Show HN: Nano PDF – A CLI Tool to Edit PDFs with Gemini's Nano Banana The new Gemini 3 Pro Image model (aka Nano Banana) is incredible at generating slides, so I thought it would be fun to build a CLI tool that lets you edit PDF presentations using plain English. The tool converts the page you want to edit into an image, sends it to the model API together with your prompt to generate an edited image, then converts the updated image back and stitches into the original document. Examples: - `nano-pdf edit deck.pdf 5 "Update the revenue chart to show Q3 at $2.5M"` - `nano-pdf add deck.pdf 15 "Create an executive summary slide with 5 bullet points"` Features: - Edit multiple pages in parallel - Add entirely new slides that match your deck's style - Google Search enabled by default so the model can look up current data - Preserves text layer for copy/paste and search It can work with any kind of PDF but I expect it would be most useful for a quick edit to a deck or something similar.

Show HN: Zero-power photonic language model–code https://ift.tt/Igt4dM9

Show HN: Zero-power photonic language model–code The model uses a 1024-dimensional complex Hilbert space with 32 layers of programmable Mach–Zehnder meshes (Reck architecture) and derives token probabilities directly via the Born rule. Despite using only unitary operations and no attention mechanism, a 1024×32 model achieves coherent TinyStories generation after < 1.8 hours of training on a single consumer GPU. This is Part 1 - the next step is physical implementation with $50 of optics from AliExpress. https://zenodo.org/records/17764289 November 30, 2025 at 12:15AM

Show HN: Local-first RAG for PDF user manuals, datasheets https://ift.tt/19YoAQN

Show HN: Local-first RAG for PDF user manuals, datasheets I work on embedded firmware for my day job, and I've found LLMs to be useful for answering questions about technical errata. But, they tend to be bad at answering highly specific questions without using some kind of search tool (if they decide to use one at all), and some user manuals are far too large to fit into a context window. I built askdocs-mcp as a way to give agents a more direct route to searching through a project's source-of-truth documents. My design constraints were that it run 100% locally, as some manuals are under NDA. It should start up fast, and let me experiment with different embedding & language models. It was built with ollama in mind, but if you can't run models locally, it will work with any OpenAI compatible endpoint. Features: - Incrementally builds and caches the set of docs. Initial start up can take a while as PDFs are chunked and ran through an embedding model, but after that, startup is near instant. - Uses the filesystem as the database - you only need `ollama` running somewhere so the tool can access an embedding and natural language model. - Provides a tool `ask_docs` for getting natural-language answers back about what the documentation says, which are annotated with page numbers the information came from. Those can be used with tool `get_doc_page` to retrieve the full page if the agent needs additional context. Because I'm providing the exact set of documents that apply to my project, I see fewer hallucinations and rabbit-hole chasing. The agent isn't relying (as much) on its latent space to answer questions, and it avoids using a web search tool which might find subtly different part numbers or protocol versions. It saves precious context as well, because the parent agent gets a concise version of what it's looking for, instead of doing the "searching" itself by loading large chunks of the document into itself. I'm sure there are improvements that can be made e.g. document chunking or the "system prompt" the tool gives to the language model - I'd love to hear your feedback, especially if you find this useful. Thanks! https://ift.tt/bNDacyd November 29, 2025 at 12:17AM

Show HN: Design a commercial bakery in an afternoon, not for $10k https://ift.tt/ZlqkMrH

Show HN: Design a commercial bakery in an afternoon, not for $10k Hi HN, I'm Rafael Mauricio, the founder of RF Modern Bakery Design. For the last decade, I've worked with hundreds of talented bakers. The same frustrating pattern kept emerging: they had the culinary skills to build a successful business, but were completely blocked by the monumental task of designing their commercial kitchen. A brilliant baker shouldn't have to also become a construction manager, HVAC expert, and workflow engineer. The traditional process is a black hole of time and money—taking 3-6 months and $10,000+ in consulting fees just to get a viable floor plan. Most independent operators can't afford this. We built RF Modern Bakery Design to bridge that gap. The Product: It's a dual-sided service. Custom Bakery Design: The time-tested, professional service for creating full, build-ready bakery concepts. Online Bakery Design Courses: This is the core of our "Show HN." We've productized our decade of expertise into video courses that teach the principles of efficient layout, equipment selection, and workflow optimization. It's like having a senior designer guide you through the entire process, empowering you to design your own space or intelligently manage a contractor. The Tech Stack: We keep it simple and focused on delivery: a static site that lets us pour 100% of our energy into creating high-quality, actionable lessons and resources. We're launching this to solve the "barrier to entry" problem in the food service industry. It's for aspiring bakery owners, culinary graduates, and even existing owners planning a renovation who need a clear, professional path to a functional and profitable layout without the prohibitive upfront cost. We'd love for you to check it out and are eager for any feedback: Landing Page: https://ift.tt/xrZmKf1 Happy to answer any questions about the business model, the design principles we teach, the build process, or the bakery industry in general https://ift.tt/xrZmKf1 November 29, 2025 at 12:31AM

Show HN: Pulse 2.0 – Live co-listening rooms where anyone can be a DJ https://ift.tt/J5LvOuN

Show HN: Pulse 2.0 – Live co-listening rooms where anyone can be a DJ I wanted to listen to music with friends who live far away. Not "watch a YouTube video together" - actually share what I'm hearing in real-time, like we're in the same room. Pulse is what came out of that. Anyone can host a live audio stream from their browser tab or system audio. Listeners join, music recognition identifies tracks automatically, and there's chat with 7TV emotes. No account required - you get an anonymous code and you're in. We're running demo rooms that stream NTS Radio and SomaFM 24/7 (indie project, not affiliated - we backlink to the original stations). There's also a "Money For Nothing 24/7" room if you want to loop that Dire Straits instrumental forever. Think of it as co-listening infrastructure. Bedroom DJs, listening parties, or just sharing your current vibe. https://473999.net/pulse November 29, 2025 at 12:09AM

Show HN: Whole-home VPN router with hardware kill switch (OpenWrt and WireGuard) https://ift.tt/XMQSRIj

Show HN: Whole-home VPN router with hardware kill switch (OpenWrt and WireGuard) With internet censorship and surveillance on the rise, ie; UK Online Safety Bill (July 2025) and Australia's social media legislation (Dec 2025) introducing mandatory age verification (read: initial step on the pathway to social credit), I wanted a privacy-first solution that protects browsing history from ISPs and third-party verification services, but not one that requires you to be an Einstein to deploy. This stack turns a Raspberry Pi (or any OpenWrt-compatible device) into a network-wide VPN gateway. Key features: - Hardware kill switch: VPN down = no internet (not a software rule that can leak) - AmneziaWG obfuscation for DPI-resistant connections - Optional AdGuard Home for DNS filtering - Works for all devices including smart TVs and IoT that can't run VPN apps Not a techie? The README is optimized for AI-assisted deployment. Feed it to your LLM of choice (Claude, GPT, etc.) and it can walk you through the entire setup for your specific hardware. Mullvad-focused but works with any WireGuard provider. MIT license. Docker deploy in testing (coming soon) https://ift.tt/l36Kcry November 28, 2025 at 04:20AM

Show HN: Yolodex – real-time customer enrichment API hey hn, i’ve been working on an api to make it easy to know who your customers are, i would love your feedback. what it does send an email address, the api returns a json profile built from public data, things like: name, country, age, occupation, company, social handles and interests. It’s a single endpoint (you can hit this endpoint without auth to get a demo of what it looks like): curl https://ift.tt/kTK5wni \ --request POST \ --header 'Content-Type: application/json' \ --data '{"email": "john.smith@example.com"}' everyone gets 100 free, pricing is per _enriched profile_: 1 email ~ $0.03, but if i don’t find anything i wont charge you. why i built it / what’s different i once built open source intelligence tooling to investigate financial crime but for a recent project i needed to find out more about some customers, i tried apollo, clearbit, lusha, clay, etc but i found: 1. outdated data - the data about was out-of-date and misleading, emails didn’t work, etc 2. dubious data - i found lots of data like personal mobile numbers that i’m pretty sure no-one shared publicly or knowingly opted into being sold on 3. aggressive pricing - monthly/annual commitments, large gaps between plans, pay the same for empty profiles 4. painful setup - hard to find the right api, set it up, test it out etc i used knowledge from criminal investigations to build an api that uses some of the same research patterns and entity resolution to find standardized information about people that is: 1. real-time 2. public info only (osint) 3. transparent simple pricing 4. 1 min to setup what i’d love feedback on * speed : are responses fast enough? would you trade-off speed for better data coverage? * coverage : which fields will you use (or others you need)? * pricing : is the pricing model sane? * use-cases : what you need this type data for (i.e. example use cases)? * accuracy : any examples where i got it badly wrong? happy to answer technical questions in the thread and give more free credits to help anyone test https://api.yolodex.ai November 24, 2025 at 07:32PM

Show HN: Safe-NPM – only install packages that are +90 days old https://ift.tt/E3aFYbB

Show HN: Safe-NPM – only install packages that are +90 days old This past quarter has been awash with sophisticated npm supply chain attacks like [Shai-Hulud]( https://ift.tt/6nWwgsH... () and the [Chalk/debug Compromise]( https://www.wiz.io/blog/widespread-npm-supply-chain-attack-b... ). This CLI helps protect users from recently compromised packages by only downloading packages that have been public for a while (default is 90 days or older). Install: npm install -g @dendronhq/safe-npm Usage: safe-npm install react@^18 lodash How it works: - Queries npm registry for all versions matching your semver range - Filters out anything published in the last 90 days - Installs the newest "aged" version Limitations: - Won't protect against packages malicious from day one - Doesn't control transitive dependencies (yet - looking into overrides) - Delays access to legitimate new features This is meant as a 80/20 measure against recently compromised NPM packages and is not a silver bullet. Please give it a try and let me know if you have feedback. https://ift.tt/vD60Pjn November 24, 2025 at 03:44AM
