Show HN: Transform passive YouTube watching into active learning https://ift.tt/1xmbMq4

Show HN: Transform passive YouTube watching into active learning I've been self-learning from YouTube for years—everything from coding to design to business skills. But I kept hitting the same wall: YouTube learning has no structure. Your knowledge gets scattered across random playlists, you're passively consuming content without real retention, and when you're confused, there's nobody to ask. I built Notetube to fix this by layering organizational tools with AI to create a proper learning system: Organizational layer: Build structured collections by topic/course/skill, visualize your learning progress with dashboards, create and track your learning goals AI layer: Automatically generates detailed notes (3000+ words for 1 hour of content) and summaries, identifies key moments with timestamps, creates personalized quizzes for retention testing, and provides a chat interface for instant help when concepts aren't clear ...plus additional features like timestamped note-taking, but I'll keep this brief.

Show HN: I built library management app for those who outgrew spreadsheets https://ift.tt/alOyzt8

Show HN: I built library management app for those who outgrew spreadsheets I've been working on librari.io for the past several months and just launched the beta version. The Problem: I have 500+ books across multiple rooms in my house and was desperately looking for an app to manage them properly. Most library management apps are either too basic or designed for institutional libraries with rigid workflows that don't fit personal use. What I Built: - Multiple libraries: manage collections in different locations - Location tracking - remember exactly which shelf each book is on - Loan management - track books you've lent to friends - Custom fields & tags - store any additional book info the way YOU think about them - Reading progress tracking - dates, duration, personal ratings - Modern UI/UX - clean & actually enjoyable to use Current Status: - Beta version live - Working on improving the responsiveness of the app and addressing initial user feedback Would love feedback! Especially curious about: - What features would make YOU actually use a library management app? - UI/UX feedback always welcome - Any book collectors here who'd be interested in beta testing? Looking forward to your thoughts! Thank you in advance. https://www.librari.io/ July 19, 2025 at 12:58AM

Show HN: Tips for getting great Text2Cypher outputs from LLMs for Graph RAG https://ift.tt/LGstZR6

Show HN: Tips for getting great Text2Cypher outputs from LLMs for Graph RAG For folks working on Graph RAG and trying to get LLMs to generate Cypher queries, I ran some experiments on the LDBC dataset and wrote a blog post about it (code is available in the link shown at the end of the post). I've been trying to answer a burning question of mine that I've had for a while now: when doing Text2Cypher, are LLMs better at interpreting graph schemas in JSON, XML or YAML? (Spoiler alert, the format barely matters, it's all to do with context engineering and retaining only the relevant parts of the graph schema in the prompt). Results on the latest LLMs are really good! The post also contains some other tips on graph schema design: I think we're in an age now where we need to design graph schema for both LLMs and humans. If you're working on Text2Cypher in any way, hope some of these ideas and experiments are useful! https://ift.tt/9ABHZ1n July 18, 2025 at 07:22PM

Show HN: I built a 2B-page search engine, independent of Google/Bing https://ift.tt/H19s35Q

Show HN: I built a 2B-page search engine, independent of Google/Bing Hi HN, For the last 18 months, I've been working solo on building a completely independent search engine from scratch. Today, I'm opening it up for beta testing and would love to get your feedback. The project powers two public sites from the same 2-billion-page index: Searcha.Page: A session-aware search engine that uses a persistent browser key (not a cookie) for better context. Seek.Ninja: A 100% stateless, privacy-first version with no identifiers at all. The entire stack is self-hosted on a single ~$4k bare-metal EPYC server in my laundry room (no cloud, no VC funding). The search pipeline is a hybrid model, using a traditional lexical index for the heavy lifting and lightweight LLMs for specific tasks like query expansion and re-ranking. It's an experiment in capital efficiency and digital sovereignty—proving you don't need Big Tech APIs to compete. I’m looking for feedback on search result relevance, speed, and the clarity of the privacy models. Please try it out and let me know what you think.

Show HN: A 'Choose Your Own Adventure' Written in Emacs Org Mode https://ift.tt/1z8ldBa

Show HN: A 'Choose Your Own Adventure' Written in Emacs Org Mode I authored and developed an interactive children's book about entrepreneurship and money management. The journey started with Twinery, the open-source tool for making interactive fiction, discovered right here on HN. The tool kindled memories of reading CYOA style books when I was a kid, and I thought the format would be awesome for writing a story my kids could follow along, incorporating play money to learn about transactions as they occurred in the story. Twinery is a fantastic tool, and I used it to layout the story map. I really wanted to write the content of the story in Emacs and Org Mode however. Thankfully, Twinery provided the ability to write custom Story Formats that defined how a story was exported. I wrote a Story Format called Twiorg that would export the Twinery file to an Org file and then a Org export backend (ox-twee) to do the reverse. With these tools, I could go back and forth between Emacs and Twinery for authoring the story. The project snowballed and I ended up with the book in digital and physical book formats. The Web Book is created using another Org export backend. Ten Dollar Adventure: https://ift.tt/gBufQrL Sample the Web Book (one complete storyline/adventure): https://ift.tt/zQUFdvc I couldn't muster the effort to write a special org export backend for the physical books unfortunately and used a commercial editor to format these.

Show HN: GitGuard - Painless GitHub PR Automations https://ift.tt/4pxaGPO

Show HN: GitGuard - Painless GitHub PR Automations Hey HN, Every team I've been on has cobbled together some sort of combination of GitHub branch protections and custom scripts to make sure that PRs conform to organization policies and best practices. Things like: - When {X} file is changed, require review from team {Y} - When a new db migration is added, ensure that a special set of tests pass - Require multiple approvals when the PR is very large - Add a special label to PRs that include breaking changes - Allow emergencies / hotfixes to break glass and bypass all of the above Most teams tend to start out with a little script running in GitHub actions to enforce all of these policies but it tends to get out of hand and become hard to maintain. PRs that should require scrutiny slip through the cracks, and others that should be allowed through are unnecessarily blocked. That's why I made GitGuard ( https://gitguard.dev/ ) GitGuard lets you write and maintain these policies in a custom DSL so simple it looks like pseudocode. The policies are checked on every single PR nearly instantly (no need to wait for a GitHub actions runner) and the results are reported in plain english. Right now policies can make simple assertions about PR metadata and take some stateful actions (adding labels, requesting review) but I'd love to hear more from HN about how GitGuard could be even more useful. https://gitguard.dev/ July 16, 2025 at 09:21PM

Show HN: Bedrock – An 8-bit computing system for running programs anywhere https://ift.tt/JEyPti2

Show HN: Bedrock – An 8-bit computing system for running programs anywhere Hey everyone, this is my latest project. Bedrock is a lightweight program runtime: programs assemble down to a few kilobytes of bytecode that can run on any computer, console, or handheld. The runtime is tiny, it can be implemented from scratch in a few hours, and the I/O devices for accessing the keyboard, screen, networking, etc. can be added on as needed. I designed Bedrock to make it easier to maintain programs as a solo developer. It's deeply inspired by Uxn and PICO-8, but it makes significant departures from Uxn to provide more capabilities to programs and to be easier to implement. Let me know if you try it out or have any questions. https://ift.tt/yXRq9Bc July 11, 2025 at 03:50AM

Show HN: StartupList EU – A public directory of European startups https://ift.tt/BEr45xC

Show HN: StartupList EU – A public directory of European startups I’m from Europe, and when I spent a summer at Stanford, I saw how different the startup ecosystem is in the US. Everything there feels connected. In Europe, it’s scattered. Hard to discover early-stage startups unless you’re in the right city or network. So I built StartupList EU, a public directory where anyone can list or browse European startups. The goals is to contribute to the EU startup ecosystem more accessible and transparent for founders, investors and operators. What it does: - Founders can submit their startup for free - Each profile includes data like team size, category, funding, revenues, location, founders and more - You can search by country, industry, name, team size, country and business model - It works across the whole EU, not just big hubs like Berlin or Paris Right now there are 34 startups listed. More are coming in daily. I’m working on better filters, API access, and a weekly newsletter. Would love your feedback: - What data would be most useful to you? - What would make this genuinely helpful for founders, investors, or researchers? - If you are from US, what's your take about EU startup ecosystem? https://ift.tt/JeYyic3 July 15, 2025 at 01:54AM

Show HN: I made a JSFiddle-style playground to test and share prompts fast https://ift.tt/WDCSuMG

Show HN: I made a JSFiddle-style playground to test and share prompts fast I built this out of frustration as I lead the development of AI features at Yola.com. Prompt testing should be simple and straightforward. All I wanted was a simple way to test prompts with variables and jinja2 templates across different models, ideally somthing I could open during a call, run few tests, and share results with my team. But every tool I tried hit me with a clunky UI, required login and API keys, or forced a lengthy setup process. And that's not all. Then came the pricing. The last quote I got for one of the tools on the market was $6,000/year for a team of 16 people in a use-it-or-loose-it way. For a tool we use maybe 2–3 times per sprint. That’s just ridiculous! IMO, it should be something more like JSFiddle. A simple prompt playground that does not require you to signup, does not require API keys, and let's experiment instantly, i.e. you just enter a browser URL and start working. Like JSFiddle has. And mainly, something that costs me nothing if I'm or my team is not using it. Eventually I gave up looking for solution and decided to build it by myself. Here it is: https://langfa.st Help me find what's wrong or missing or does not work from you perspctive. P.S. I did not put any limits or restrictions yet, so test it wisely.

Show HN: I Built a Stick-On Wireless Lamp That Installs in 30 Seconds https://ift.tt/TFrNXyi

Show HN: I Built a Stick-On Wireless Lamp That Installs in 30 Seconds Hi HN! I recently built a simple, rechargeable wall lamp that doesn't require any tools, wires, or drilling. It sticks to surfaces using adhesive pads, rotates 360°, and charges via USB-C. The goal was to make lighting *super minimal, renter-friendly, and easy to install*. The idea came from personal frustration — I live in a rented apartment where I can’t drill holes, and I wanted a modern-looking light I could reposition easily. I know this isn’t a software product, but I figured some of you might appreciate the problem-solving side of it — designing minimal hardware that’s useful, elegant, and simple. Would love feedback on the product or the landing page: Happy to answer any questions about the design, battery, lighting specs, remote control logic, etc. Thanks! https://ift.tt/IvsNtCJ July 13, 2025 at 01:56AM
