Show HN: Open-source private home security camera system (end-to-end encryption) I needed a security camera inside my house, one that would send motion notifications to my smartphone and would allow me to livestream remotely. However, I could not find one that I could trust due to privacy concerns. Many of them upload the plaintext of videos to their servers and none is fully open-source as far as I know. Therefore, I decided to use my spare time to build one from scratch. Called Privastead (as in Private Homestead), it uses OpenMLS for end-to-end encryption (between the camera local hub and the smartphone) and is mostly implemented in Rust (except for part of the Android app that is implemented in Kotlin). The system is functional now and I've been using it in my own house for the past couple of weeks. Based on some of the discussions I've seen online, it seems like there are other users who are also concerned with the privacy implications of home security cameras. Therefore, ...

Show HN: Jinbase – Multi-model transactional embedded database Hi HN ! Alex here. I'm excited to show you Jinbase ( https://ift.tt/834HKoY ), my multi-model transactional embedded database. Almost a year ago, I introduced Paradict [1], my take on multi-format streaming serialization. Given its readability, the Paradict text format appears de facto as an interesting data format for config files. But using Paradict to manage config files would end up cluttering its programming interface and making it confusing for users who still have choices of alternative libraries (TOML, INI File, etc.) dedicated to config files. So I used Paradict as a dependency for KvF (Key-value file format) [2], a new project of mine that focuses on config files with sections. With its compact binary format, I thought Paradict would be an efficient dependency for a new project that would rely on I/O functions (such as Open, Read, Write, Seek, Tell and Close) to implement a minimalistic yet reliable persistenc...

Show HN: wazero compiler ported to 4 new OSes Release 1.8.2 of wazero, the zero dependency WebAssembly runtime for Go, brings the amd64 compiler to 4 new OSes: NetBSD, DragonFly BSD, illumos and Solaris.

Show HN: I built an extension to contact Airbnb hosts direcly Hey HN, Over the years, I’ve found myself frustrated with the extra fees Airbnb. While they provide a lot of convenience, the service fees often stack up to a point where they overshadow any potential savings. I started wondering if there was a way to connect directly with property hosts and skip the middleman entirely. That curiosity led me to build getaway.direct, a free Chrome extension that helps travelers save money. It works like this: 1. You browse listings on Airbnb. 2. The extension scans for direct booking links, host websites, or social media profiles where you can reach out to the host directly. 3. It shows those results instantly, so you can compare prices, avoid service fees, and book smarter. The main idea is to provide transparency. A lot of hosts already have their own websites but rely on platforms like Airbnb for visibility. This tool helps surface those direct options, which can often save you 10-20% per ...

Show HN: Managed Redux Toolkit: Autogenerate Your RTK Definitions Redux Toolkit (RTK) provides a lot of primitives to build performant frontend applications. Celestial generates RTK code for your backend (with additional features), exposing an intuitive hook-based API. So you can have all the benefits of RTK without having to familiarise yourself with the underlying framework. Essentially, we write the backend wiring code for your frontend. You get simple-to-use hooks, which implement advanced backend sync & state management patterns. You also get a fast, snappy application out-of-the box. You can also think about it like this: Celestial generates a unified state layer that contains your server state and any other state that you decide to store. It exposes hooks to interact with the state, while constantly keeping client state in sync with the backend. Your UI simply plugs into the state layer using a hook-based API to manage data flow for your web app. UI development can broadly b...

Show HN: MyDuck Server – Supercharge MySQL and Postgres Analytics with DuckDB Hello HN! We're excited to announce MyDuck Server, an open-source project that seamlessly integrates the analytical power of DuckDB with your existing MySQL & Postgres databases. *Backstory* Currently, there are no fully satisfactory open-source OLAP solutions for MySQL & Postgres. In the MySQL ecosystem, HeatWave offers close integration, but it's a proprietary, commercial product from Oracle. The Postgres community has seen promising DuckDB-based extensions emerge, including the official pg_duckdb. However, extensions can introduce isolation concerns in mission-critical environments. Consequently, many organizations resort to setting up complex and costly data movement pipelines using tools like Debezium, Flink, or other commercial solutions to replicate data from MySQL & Postgres to OLAP systems (e.g., Snowflake, BigQuery, ClickHouse) or Lakehouses (e.g., Delta Lake + Spark).

Show HN: Drafting AI – Human-in-the-loop AI automation for ops teams' email Hi HN, I'm Jared from Drafting AI ( https://ift.tt/iOq9GZ1 ). We're a Chrome extension that helps operations and customer support teams work through their inboxes more efficiently. Here's a quick demo video: https://www.youtube.com/watch?v=PCDqAMaYx2Q We believe AI can be deployed more widely when you mitigate hallucinations through human-in-the-loop review. This led to two decisions: 1. A Chrome Extension is ideal for presenting actions in third-party apps for human review. When AI suggests issuing a refund via Shopify, what better way to show it than through Shopify's own refund interface? 2. AI should "draft" responses but not submit them. For instance, it’ll open Shopify admin and fill in refund details, but won't click "submit." This gives the user full control to approve, modify, or discard the AI's suggestions. We believe this "drafting" UX of pre...

Show HN: Open-Source Pull Request AI Reviewer Hey HN, Over the last year, I’ve reviewed more than 1000 code changes. Most of the time was spent catching obvious mistakes rather than debating complex design decisions. If we estimate ~10 minutes per review, that’s 160+ hours spent reviewing code in just one year. So I thought: could I get some of that time back using LLMs? That's why I spent the last few weekends building Presubmit.ai, an open-source AI reviewer that runs as a Github Action right when you open a Pull Request. The results so far are promising: I estimate it can reduce the review time by 50%, which in my case would mean I save 80hours (~10 working days) per year. Unlike similar SaaS solutions, the goal is not to replace the human reviewer but to highlight obvious mistakes early, spot security vulnerabilities and give more context about the change. I like to think of it as a “pre-reviewer”. Some of its features are: * Line-by-line comments * PR summarization * Title gen...

Show HN: VS Code extensions that display CGM blood glucose levels in status bar As a Type 1 diabetic, I need to continuously monitor my blood glucose levels. I’ve implemented a couple of Visual Studio Code extensions that retrieve the latest blood glucose readings from your CGM and display them in your VS Code status bar. One VS code extension uses the Nightscout CGM to retrieve the blood glucose readings. It requires users to run the Nightscout application on a hosted server. A nice benefit of Nightscout application is that it works with all the major CGM devices. However, a slight drawback of this option is that it requires a hosted third party software (Nightscout) for proper functionality. I’ve also implemented a Visual Studio code extension for those (like myself) that use the Freestyle Libre CGM. This version connects directly to LibreLinkUp to retrieve the latest blood glucose readings and display them in your VS code status bar. This removes the dependency for the intermediary ...

Show HN: An AI that reliably builds full-stack apps by preventing LLM mistakes Hey HN! Previous CERN physicist turned hacker here. We've developed a way to make AI coding actually work by systematically identifying and fixing places where LLMs typically fail in full-stack development. Today we're launching as Lovable (previously gptengineer.app) since it's such a big change. The problem? AI writing code typically make small mistakes and then get stuck. Those who tried know the frustration. We fixed most of this by mapping out where LLMs fail in full-stack dev and engineering around those pitfalls with prompt chains. Thanks to this, in all comparisons I found with: v0, replit, bolt etc we are actually winning, often by a wide margin. What we have been working on since my last post ( https://ift.tt/1exYjmr ): > Handling larger codebases.

Show HN: Agentic Evaluators for Agentic Workflows (Starting with RAG) Hey all! Thought this group might find this interesting - new approach to evaluating RAG pipelines using 'agents as a judge'. We got excited by the findings in this paper ( https://ift.tt/U0FyOcq ), about agents producing evaluations closer to human-evaluators, especially for multi-step workflows. Our first use case was RAG pipelines, specifically evaluating if your agent MISSED pulling any important chunks from the source document. While many RAG evaluators determine if your model USED its chunk in the output, there's no visibility on if your model grabbed all the right chunks in the first place. We thought we'd test the 'agent as judge', with a new metric called 'potential sources missed', to help evaluate if your agents are missing any important chunks from the source of truth. Curious what you all think! https://ift.tt/7dVuqit November 20, 2024 at 11:57PM

This is Adil, Salman, Co and Shuguang and we're excited to introduce archgw [1], an open source intelligent proxy for agents built on Envoy [2]. Arch moves the critical but crufty work around safety, observability, and routing of prompts outside business logic. Arch is a uniquely intelligent infrastructure primitive, engineered with purpose-built fast LLMs [3] for tasks like intent detection over multi-turn, parameter identification and extraction, triggering single/multiple function calls, and offers convenience features to auto dispatch LLM calls for summarization based on data from your APIs via system prompts configured in archgw. Today, the approach to build a smart production-ready agent is weaving together a large set of mono-functional opinionated libraries, adding extra layers like LLM-based preprocessing to determine things like relevance and safety of the user's prompt (e.g. applying...

As a cofounder of Couchbase, I pioneered mobile sync, and I’ve always wanted to bring the speed and reliability of local-first data to the web, incubating PouchDB among other efforts. I learned the constraints of real world financial applications at McKinsey & Company FinLab, and Merkle integrity research at Protocol Labs taught me smart contract data structures. As part of the JavaScript community (and early hosting provider for NPM) I’ve been waiting, and now with the availability of APIs like Passkeys and Origin Private Filesystem, I’m happy to say the browser is ready to support embedded databases. Front-ends are a lot easier to write when your database handles live sync for you, but the existing solutions rely on heavyweight cloud APIs instead of putting the smarts at the edge, where it belongs. I started from a different set of constraints, and arrived at a lightweight embedded database that uses a...

Show HN: FastGraphRAG – Better RAG using good old PageRank Hey there HN! We’re Antonio, Luca, and Yuhang, and we’re excited to introduce Fast GraphRAG, an open-source RAG approach that leverages knowledge graphs and the 25 years old PageRank for better information retrieval and reasoning. Building a good RAG pipeline these days takes a lot of manual optimizations. Most engineers intuitively start from naive RAG: throw everything in a vector database and hope that semantic search is powerful enough. This can work for use cases where accuracy isn’t too important and hallucinations are tolerable, but it doesn’t work for more difficult queries that involve multi-hop reasoning or more advanced domain understanding. Also, it’s impossible to debug it. To address these limitations, many engineers find themselves adding extra layers like agent-based preprocessing, custom embeddings, reranking mechanisms, and hybrid search strategies. Much like the early days of machine learning when we manually...

Show HN: Konga Beat – A custom track editor for Donkey Konga 2 and 3 Howdy HN! For those who don't know, back in the early 2000s, Nintendo and Namco developed a series of music rhythm games for the GameCube featuring Donkey Kong called Donkey Konga: https://ift.tt/9X71OYT The Donkey Konga games borrowed heavily from Taiko no Tatsujin (another music rhythm game by Namco). However, instead of taiko drums, the player would use DK Bongos to jam along with music from different eras and genres. Long story short, I figured out how to add custom tracks to some of the Donkey Konga games (Donkey Konga 2 and 3) but found the entire process cumbersome, so I decided to make a dedicated editor. It was a lot of fun to make, and I hope others get some enjoyment out of it too! https://ift.tt/bBXh8WO November 13, 2024 at 11:39PM

Show HN: Next.js GitHub Markdown Blog This project allows you to easily add a nice looking, mobile-friendly blog to your existing NextJS app without a lot of heavy dependencies or complex stuff to configure. You just set up a repo on GitHub with some markdown files with some metadata at the top, and it will automatically retrieve and convert the markdown to rich html/css blog posts that works well with SEO. I made it for my own webapp because I wanted something simple and easy and didn't want to deal with a complex library/system that does tons of stuff I don't care about. https://ift.tt/KtILqU9 November 13, 2024 at 12:10AM

Show HN: DocSend, but Made 10x Cheaper Hey HN, founder of Peony here. Most founders use DocSend to share investment or sales docs and have to pay $65 to $300 a month to get the security and analytics features. It pains me to see startups getting ripped off when the availability of technologies such as Clickhouse makes real time analytics almost a trivial feature to implement in 2024. We think it's time to end the carnage and democratize the technology. We set ourselves a high bar: we don't want to build another DocSend - we want it to be a far more superior product and also 10x cheaper. After a couple of months of work, I'm proud to share with you Peony - a first preview into what we believe will be the future of file sharing. In addition to the analytics and security features you'd expect coming from DocSend, we built Peony to be flexible and adaptable across all your file sharing needs and give you the ability to deeply personalize your file share per recipient.

Show HN: I made a tiny device for automatically recording digital pianos Hey HN! A few years ago, I left my cushy big tech job to make hardware. And made the device I always wanted - an automatic piano recorder! I usually play piano improvisationally, and manually hitting record never meshed well with that. But there are always moments I wish I recorded, and now they are! Hopefully it scratches a similar itch for some of you as well!

Show HN: I made a minimalistic AI calendar creator to accelerate daily planning Hey Hacker News! To test implementing AI (and paywalls tbh) in software for the first time, I made this simple calendar creator (no mail address required) that lets a person create a calendar based on his needs and availability and export it to his calendar app, pdf or receive a daily newsletter with his daily tasks (and more). After wrestling with different models (f.e. with huggingface) and encountering different problems, I decided to use ChatGPT's models, tune them a little and see how the result works out. ChatGPT's low price enables me to give users the opportunity to create calendars for free and without a mail address required. Demo video: https://youtu.be/UeZmqXcU5fY?feature=shared The website/tool includes: - Creating your calendar based on a title, date range and a description - Editing and "polishing" the calendar until getting a desired result - Exporting the calendar to your ...

Show HN: httpclock. A useless way to tell the time with HTTP status codes… I made this a few months back as a fun little project and it has absolutely no utility whatsoever. The server returns the current time in the request's status code — i.e., as long as the time can be mapped to a valid HTTP status code (e.g., 4:04pm -> 404 Not found) the server returns that status code for the request. Example: https://ift.tt/OWc9pBg The httpclock.com domain detects timezone by IP and redirects to the respective subdomain such as pt.httpclock.com (but will fall back to UTC) A browser will show a blank page for most of the day given the number of valid status codes, but you can check other timezone subdomains, e.g. `curl -I https://ift.tt/UisASw5 ` Note: "Invalid" times will return 999 with no content. Anyway, I hope you enjoy this very useless clock. I plan to post the code on GitHub soon since I may as well. Thanks! https://httpclock.com November 10, 2024 at 10:05PM

Show HN: ChatGPT for calorie tracking. Frictionless diet and exercise tracking Hi, I'm Steve and I've built this mobile app to solve my very long-standing problem of not consistently using any calorie tracking apps due to the poor UX (many clicks, too much friction). So, although I am not the best UI/UX designer, I have tried to remove friction at every corner with Journable. This applies to the 1. Tracking experience: Chat-based interface (think ChatGPT) to log food/exercise 2. Onboarding experience: No login screen, no measurements or goals, straight to the main chat window 3. Photo entries: Just take a picture of your plate and done That said, I'm not the best UI/UX designer so I would really appreciate any feedback on the app, and I welcome any and all comments & suggestions. Should I make it easier? Faster? Simpler? Does it need more color? Keen to hear it all! https://ift.tt/l5Q2ZpV November 8, 2024 at 01:22AM

Statewide ‘Daylighting Law’ Warnings Begin Nov. 11, 2024 By Madhu Unnikrishnan Parking this close to an intersection could soon get you a warning. Next year, you could face a fine. On Nov. 11, 2024, we will begin issuing written warnings for vehicles parked within 20 feet of any crosswalk in the direction of approaching traffic. For example, you could receive a warning if you park less than 20 feet in front of a stop sign. We’re doing this to comply with the statewide “Daylighting Law” (Assembly Bill 413). It went into effect at the beginning of 2024. Starting Jan. 1, 2025, we will begin issuing citations to comply with California law. Fines will start at $40. This law...

Show HN: NewsCatcher's Hyperlocal News API – Granular City-Level News Feeds We’ve launched NewsCatcher’s Hyperlocal News API to provide city-level news feeds for market analysis, localized apps, and data analytics. Why We Built It: Aggregating hyperlocal news is complex. Local news comes from diverse sources, many covering national topics, making it hard to isolate local events like transit updates, crime, extreme weather alerts, or infrastructure projects. Searching by location alone can lead to irrelevant results, especially with city names that overlap or match common words (e.g., Orange, Lake). What It Does: Our API provides precise, location-based news by processing 185K articles daily and tagging each with its associated_town down to the town level with 92% accuracy. Covering 31,000 U.S. locations, it uses advanced NLP to accurately associate location names, even when they’re common words. It enables you to: - Access near-real-time, location-focused news feeds - Filter by top...

Show HN: I wrote an open-source browser alternative for Computer Use for any LLM Hey HN, I made Browser-Use, an open-source tool that lets (all Langchain supported) LLMs execute tasks directly in the browser just with function calling. It allows you to build agents that interact with web elements using natural language prompts. We created a layer that simplifies website interaction for LLMs by extracting xPaths and interactive elements like buttons and input fields (and other fancy things). This enables you to design custom web automation and scraping functions without manual inspection through DevTools. Hasn't this been done a lot of times? Good question, as a general SaaS tool yes, but I think a lot of people are going to try to make their own web automation agents from scratch, so the idea is to provide groundwork/library for the hard part so that not everyone has to repeat these steps: - parse html in a LLM friendly way (clickable items + screenshots) - provide a nice function ...

Show HN: A free multiviewer to watch major news events like elections Hey HN! I'm a Product Manager at the FT in the UK, and VidGrid is something I've been working on for years in my own time. It's just got a major update just in time for the election. The idea is a way to watch lots of different news streams at the same time, as if you're in a control room or news gallery for the very latest info. I tried to prioritise usability and speed. All streams are third-party sourced (from broadcaster's own links). You can now sign up for an account to save/favourite your own streams, and it has better keyboard and drag and drop support. I've also fixed a ton of bugs from the last version. Happy to answer questions about it, or about news media at this time of year in general! Enjoy, and have a good evening. https://vidgrid.tk.gg November 5, 2024 at 09:13PM

Show HN: OpenQuest, connect with people around a shared goal for a short time Hey everyone! I built a little side project called OpenQuest over the last three weeks, and I'm looking for some feedback to see if it's worth taking further. The idea is simple: it's a place to create a chat room where you can connect with people (a maximum of 8) who have the same goal as you, for a short time (7 days for now). Think of it as a way to stay motivated, hold each other accountable, or simply work together with new people on something specific. Some examples can be: - Following a programming course - Reading a book - Getting back to the gym - Cleaning up your home - Shopping for a mechanical keyboard For example, here's a room I created to get things going: https://ift.tt/wfGste4 Why did I build this?

Show HN: X.infer-Framework agnostic computer vision inference I spent the past 3 weeks building x.infer, a Python package that lets you run computer vision inference on a framework of choice.

Repo - https://ift.tt/JkGDeU0 Colab quickstart - https://ift.tt/ISPsX0w... Why did I make this? It's mostly just for fun. I wanted to practice some design pattern principles I picked up from the past. The code is still messy though but it works. Also, I enjoy playing around with new vision models, but not so much learning about the framework it's written with. I'm working on this during my free time. Contributions/feedback are more than welcome! Hope this also helps you (especially newcomers) to experiment and play around with new vision models. https://ift.tt/JkGDeU0 November 2, 2024 at 10:41PM

Show HN: Exploring Russian Election Interference with Graphiti Hi HN, we're Jack and Daniel from Zep. We've built a visual exploration tool and AI assistant for analyzing Russian election interference in the run-up to next week's US elections. The Explorer uses Graphiti, Zep's open-source temporal Knowledge Graph library. Graphiti autonomously creates dynamic, temporally-aware knowledge graphs representing complex, evolving relationships between entities. To offer users a detailed view of Russian state operations and related topics, we populated the graph with over 50+ sources. These include US DOJ indictments, research by US and foreign governments, research by non-governmental organizations, and media articles. Using the graph, you can explore which US organizations and individuals are implicated in these efforts and learn how private entities (such as OpenAI, Meta, and others) have responded. Two operations stand out in this dataset: Doppelganger and Tenet Media. - D...
