Show HN: FastIndex, an open-source search engine indexation tool There's a lot of paid search engine indexation tools out there and I wanted to create my own. Been working as an engineer for over a decade now and my open-source contribution has always been something I wanted to do. Thus I decided to create FastIndex, an open-source search engine indexation alternative to paid solutions such as TagParrot, URLMonitor, Omega Indexer and many more.

Show HN: A new, improved, and open-source clipboard history Chrome extension https://bit.ly/3XWudnI

Show HN: A new, improved, and open-source clipboard history Chrome extension Hey all! I recently built a new, improved, and open-source chrome extension that allows you to access, track, and manage your clipboard's history! It's very useful for things like refactoring code, finding obscure commands, and backing up form data. Existing solutions are either closed-source, slow, riddled with ads, or all of the above. My goal is to make this extension the most trustworthy, performant, and easy to use version! Your feedback would be very much appreciated, thanks! Extension: https://bit.ly/3XYvAm7...

Show HN: A toxic conversation with ChatGPT for research I started this conversation with ChatGPT as an exercise to explore the ways in which young folks can be influenced by peers into toxic ways that may lead them astray. So instead of asking generally, I went for a devil's advocate approach. I am actually amazed and impressed by how suggestive and understanding of current youthful traits that ChatGPT is aware of. Any suggestions for other questions? When you pose a question, let me know what you intend on establishing from the response. https://bit.ly/3TJShrI September 25, 2024 at 05:08AM

Show HN: Oodle – serverless, fully-managed, drop-in replacement for Prometheus https://bit.ly/4efFC7R

Show HN: Oodle – serverless, fully-managed, drop-in replacement for Prometheus Hello HN! My co-founder, Vijay and I are excited to open up Oodle for everyone. We used to be observability geeks at Rubrik. Our metrics bills grew like 20x over 4 years. We tried to control spend by getting better visibility, blocking high cardinality labels like pod_id, cluster_id, and customer_id. But that made debugging issues complicated. App engineers hated blocking metrics, and blocking others' code reviews was not fun for platform engineers either! Migrations (and lock-ins) were very painful, the first migration from Influx to Signalfx took 6+ months and the second migration from Splunk took over a year. Oodle is taking a new approach to building a cost-efficient serverless metrics observability platform. It delivers fast performance at high scale. We leverage custom storage format on S3, tuned for metrics data. Queries are serverless. The hard part is how to achieve fast performance while optimizing for costs (every cpu cycle, storage/memory byte counts!). We've written about the architecture in more detail on our blog: https://bit.ly/4gA0RTC...

Show HN: OpenFreeMap – Open-Source Map Hosting https://bit.ly/3BhOHyD

Show HN: OpenFreeMap – Open-Source Map Hosting Hi HN, After 9 years of running my own OpenStreetMap tile server infra for MapHub ( https://bit.ly/3XypM17 ), I've open-sourced it and launched OpenFreeMap. You can either self-host or use our public instance. Everything is open-source, including the full production setup — there’s no 'open-core' model here. Check out the repo ( https://bit.ly/3zBqYc1 ). The map data comes from OpenStreetMap. I also provide weekly full planet downloads both in Btrfs and MBTiles formats. I aim to cover the running costs of the public instance through donations. Looking forwards for your feedback. https://bit.ly/4e8VCbW September 24, 2024 at 12:59PM

Show HN: An expression parser supporting multiple types https://bit.ly/3TENoQA

Show HN: An expression parser supporting multiple types This C library is part of a main project aimed at providing a reactive key-value (KV) database. The data is typed (numbers, strings, dates, or booleans) and can include formulas with references to other entries. Clients connected to this database receive a real-time data stream with updates to the subscribed keys, allowing them to react to changes and their dependencies. Essentially, it’s like building a distributed Excel, where data and formulas dynamically update across the system. I couldn’t find any libraries that offered the full set of features I needed for evaluating expressions, so I decided to create my own. This sub-project is open-source and available on GitHub. Feedback is welcome! https://bit.ly/3XTTD5p September 24, 2024 at 11:30AM

Show HN: Trakk.js – Real-Time Code Monitoring and Docs Generation https://bit.ly/47zaWw3

Show HN: Trakk.js – Real-Time Code Monitoring and Docs Generation Hello HN, I’ve developed an npm package called trakk-js, designed to help frontend developers while they're developing their applications locally. It provides a clean UI panel that loads on top of your web application, and presents all of the below in real-time : - Tracks function calls, errors, requests, and user interactions (with screenshots) with detailed insights. - Filters unimportant events and shows app stats (slowest/fastest loops, frequent calls, etc.). - Generates automatic documentation with a single click. Why use it? - Debugging: Clean UI to trace your app’s code flow in real-time. - Onboarding: Newcomers can easily understand app behavior by tracking event flow. - Documentation: Generates accurate, up-to-date docs automatically after code changes. It's framework agnostic, works with .js, .jsx, .ts, .tsx files, and doesn’t modify your code. It's currently in test mode so feel free to check it out. Looking forward to your feedback! https://bit.ly/47yoIyV September 23, 2024 at 12:01PM

Show HN: I built a tool to roast landing pages using AI agents I built a tool to roast landing pages with AI agents. I was gathering feedback from watching landing page roast videos, and figured out I could prompt LLMs to analyse a screenshot and roast based on the same criteria. It's not 100% accurate yet, but it has been really insightful when I've tested it on my own websites. Let me know what you think! https://bit.ly/3B8mk5K September 23, 2024 at 02:05AM

Show HN: PlayCodeAI – A tool I created to let my kid create their own videogames https://bit.ly/47DT1UI

Show HN: PlayCodeAI – A tool I created to let my kid create their own videogames Hi hn, Its been a while since my kid has been dreaming to make videogames, as you know, the entry bar is high, too many technical details are involved. A few months ago, we started making games, we have tried many different ways, from dragging blocks to write code with a high-level library to make it simple, it is still too much work. Getting into the AI boat, I decided to give it a try for making games, turns out that it works super nicely, still, you still have many technical concepts involved, what language should the game be written in? where do you store the file/assets? how do you run it? I decided creating a simple playground where most of the tech details are already defined, html/javascript due to the portability they provide, we can get the code and see the result right away, same way, we can easily export it and upload it to a server. So far, the results are amazing, my kid has managed to create 10 simple games in a few hours with no help at all (the landing page includes screenshots from these). I strongly believe that this can help many other people to bring their ideas to life. As of now, the tool is simple, it runs on the client side, requiring an OpenAI API Key to interact with the models, it has the problem that only paid users can access this and I hope to remove that barrier soon but this was the simplest/fastest way to get things done. A big limitation relates to image loading, many images have CORS limitations that chatgpt can't detect, games without images aren't fun and I hope to solve this soon (suggestions accepted). I'd also love making it simple to share the results with others. Anyway, if your kid is willing to make a videogame, I encourage you to try this out, any feedback should help me to polish this to be usable for others. Thanks. https://bit.ly/3BhumJJ September 22, 2024 at 09:19PM

Show HN: Inbound Email (SMTP) to Webhook Here's my first (hopefully of many) open source release. A minimal script to receive emails via SMTP, parse content (including headers), store attachments in Amazon S3, and forward email content to a webhook. I use it to power DMARC report storage and email content testing. Some of the big email API providers have inbound APIs but costs can rack up fast if you're using them at scale. Hence why I built this. https://bit.ly/3MVyTnK Features - SMTP server to receive emails concurrently - Parses incoming emails using mailparser - Uploads attachments to Amazon S3 - Forwards parsed email content to a specified webhook - Configurable via environment variables - Handles large attachments gracefully - Queue system for processing multiple emails and webhook requests simultaneously https://bit.ly/3MVyTnK September 22, 2024 at 07:19AM

Show HN: A tool to easily convert any web page into an eBook https://bit.ly/47CBjkt

Show HN: A tool to easily convert any web page into an eBook I’ve built a tool that allows you to convert any web content into an ebook with just a few clicks. The idea came from my need to frequently save articles or web pages as ebooks for offline reading and sharing. However, I found existing tools either too complex or lacking flexibility, so I decided to create something simpler, faster, and that supports both EPUB and PDF formats. Key Features: - Quick Conversion: Input a list of URLs, with each URL treated as a chapter, and the tool will automatically generate an ebook in either EPUB or PDF format. - Content Optimization: It automatically optimizes the content for better structure and readability in ebook format. - Multilingual Support: It works with web pages in multiple languages. EPUB or PDF Output: You can choose the format you prefer. - Send Directly to Kindle: You can send the generated ebook directly to your Kindle device from Ebookany. I’d love to get feedback from the community to help improve the tool and add new features. Feel free to try the tool here: https://bit.ly/3MSTCZf . Thank you for reading, and I look forward to your thoughts! https://bit.ly/3MSTCZf September 21, 2024 at 07:59AM

Show HN: Turn your dreams into reality with this life planner app https://bit.ly/3TDDBKF

Show HN: Turn your dreams into reality with this life planner app Hi, this is Ygee, and I'd like to share the story of Y-Pod. Most people believe their big dreams are impossible to achieve, so they settle for less—not because they can’t, but because they feel overwhelmed and disconnected from that distant future. I felt the same way. It was a struggle juggling multiple apps like notes, to-dos, and calendars to plan my goals. I realized a dedicated app to organize my life goals would not only help me but also allow me to showcase my technical and creative skills. That’s how Y-Pod was born — to bridge the gap between big lifelong dreams and small daily actions, empowering users to turn their dreams into reality. My hope is that it will help others live their dream lives and, in doing so, make the world a better place. https://apple.co/3BdZHgi September 21, 2024 at 01:54AM
