Show HN: iCal RSVP Helper https://ift.tt/Ql1Tmdv

Show HN: iCal RSVP Helper Hi HN, We use HEY for Work at my startup, which doesn't have a calendar integration. This is mostly fine, as we can simply use our private calendars, but has a major drawback: We can't reply to invitations in an easy way. I made this microsite to help with this problem until they implement simple Yes/No/Tentative buttons in HEY. It's fully client-side, and gives you the ICS-file you need to attach in an email, and the correct address it needs to be sent to as well - just select your file and RSVP. Hope it's useful for someone else too! https://rsvp.klungo.no/ May 24, 2023 at 11:19AM

Show HN: File-by-file AI-generated comments for your codebase https://ift.tt/yZw7kdF

Show HN: File-by-file AI-generated comments for your codebase My friends and I were complaining about having to decipher incomprehensible code one day and decided to pass the code through GPT to see if it could write easily understandable comments to help us out. It turns out that GPT can but it was still a hassle to generate comments for large files. So we decided to develop a basic web application that automatically integrates with your Github repository, generate comments, create a pull request and send you an email when it is all done. There is definitely a lot more that can be done but we wanted to gain feedback on whether this is a problem that you face too. Do you often find it challenging to understand complex code? Do you have difficulties in writing informative comments? And if so, would you find value in a tool that can automatically generate comments for your code? Really appreciate any feedback and suggestions! Thanks in advance! https://ift.tt/ySIjk1x May 23, 2023 at 06:16PM

Show HN: Blotter – An interactive, never ending music video https://ift.tt/5Bce30j

Show HN: Blotter – An interactive, never ending music video One day I was listening to a playlist and wished there could be some cool visuals to go along with it. Blotter is a proof of concept I hacked together that does a bit of audio recognition combined with a few generative AI models (both text and img) to create visuals that are relevant to the song. The video stream is generated in real time at 24fps - you can try it yourself by requesting visuals in the Twitch chat using the "!v" command! Right now it's mostly a fun hack project, but I am tinkering with new model architectures for higher fidelity video as well as an interactive tool so people can make videos with their own audio files. I'd love to hear any feedback or suggestions, thanks! https://ift.tt/S1UDV4F May 23, 2023 at 02:21AM

Show HN: Psychic - An open-source integration platform for unstructured data https://ift.tt/lRA0eaH

Show HN: Psychic - An open-source integration platform for unstructured data My cofounder and I used to work at Robinhood where we shipped the company’s first OAuth integrations, so we know a lot about how data moves between companies. For example, we know that the pain of building new API integrations scales with the level of fragmentation and number of competing "standards". In the current meta, we see this pain with a lot of AI startups who invariably need to connect to their customers data, but have to support 50+ integrations before they even scale to 50+ customers. This is the process for an AI startup to add a new integration for a customer: - Pore over the API docs for each source application and write a connector for each - Play email tag to find the right stakeholders and get them to share sensitive API keys, or give them an OAuth app. It can take 6+ weeks for some platforms to review new OAuth apps - Normalize data that arrives in a different formats from each source (HTML, XML, text dumps, 3 different flavors of markdown, JSON, etc) - Figure out what data should be vectorized, what should be stored as SQL, and what should be discarded - Detect when data has been updated and synchronize it - Monitor when pipelines break so data doesn’t go stale This is a LOT of work for something that doesn’t move the needle on product quality. That’s why we built Psychic.dev to be the fastest and most secure way for startups to connect to their customer’s data. You integrate once with our universal APIs and get N integrations with CRMs, knowledge bases, ticketing systems and more with no incremental engineering effort. We abstract away the quirks of each data source into Document and Conversation data models, and try to find a good balance to allow for deep integrations while maintaining broad utility. Since it’s open source, we encourage founders to fork and extend our data models to fit their needs as they evolve, even if it means migrating off our paid version. To see an example in action, check out our demo repo here: https://ift.tt/p0er2oB We are also open source and open to contributions, learn more at docs.psychic.dev or by emailing us at founders@psychic.dev! https://ift.tt/t8hMVPb May 22, 2023 at 06:41PM

Show HN: SpaceBadgers – Free and Libre SVG Badges Greetings, Hacker News community! I am thrilled to present SpaceBadgers, a new free and open-source SVG badge generator I've been working on. It's located at badgers.space. SpaceBadgers is born out of the desire to offer more flexibility and customization for project badges, often used in open-source projects. It's fully open source, provided under the permissive MIT license, and will always be provided for free. The core badge worker is written in Rust, and so is the library behind it, which you can also find on crates.io under the name spacebadgers. I am excited to receive your feedback and suggestions. Check it out and let me know what you think in the comments. Contributions are also welcomed and appreciated.

Show HN: A simple echo server for testing HTTP clients https://ift.tt/GxHnuvN

Show HN: A simple echo server for testing HTTP clients I have developed an application called "echoserver" and I would like to share its details on Hacker News. The purpose of "echoserver" is to simplify the testing of HTTP clients. It functions as an echo server, meaning it responds to requests by echoing back the received data. This allows users to simulate various server responses and test their HTTP clients accordingly. With "echoserver," users can generate custom responses by specifying the desired status code, headers, and response body. This flexibility enables thorough testing of HTTP clients and simplifies the process of verifying client behavior under various scenarios. Whether it's testing error handling, handling specific headers, or evaluating performance under different response sizes, "echoserver" provides a convenient solution. Overall, "echoserver" aims to streamline the testing process for developers and enhance their ability to verify the functionality and robustness of their HTTP clients. Its simplicity, versatility, and user-friendly interface make it an invaluable tool in the development and testing workflow. I invite the Hacker News community to explore and provide feedback on the app, as I believe it has the potential to greatly benefit developers and testers worldwide. https://echoserver.dev/ May 21, 2023 at 02:56PM
