Show HN: Sine Wave Speech, a real-time audio effect in Rust->WASM Source code: https://ift.tt/enT59Rc An interactive website for exploring how human speech can be reduced to just a few sine waves and still be intelligible - or at least recognized to be a human voice. On top of that, I've added various ways to make the sound more musical. The sound effect is based on research from the 80s, which has largely been forgotten by then. To have the effect run in real-time in the browser, I opted to use Rust compiled into WebAssembly. Still, I had to rewrite some linear algebra routines. More about that experience in the blog post: https://ift.tt/1CRE9X7 https://ift.tt/HbOw6lr December 28, 2024 at 09:04PM

Show HN: I made a web app that generates resumes and cover letters for free https://ift.tt/mPlyC41

Show HN: I made a web app that generates resumes and cover letters for free I wanted to share a project I've been working on since October '24. It's an AI-powered toolkit designed to help job seekers shorten their job hunt and advance their careers. The idea came from my own experiences and frustrations with the job application process, both as a job seeker and a hiring manager. I wanted to simplify and streamline how people present their skills and experiences to potential employers. By leveraging AI (GPT-4o), CareerCrate.io can generate tailored application materials in minutes, for free - no sign up required. I'm also developing some optional advanced features like Pursuit™, a tool for job seekers, and SkillForge™, a personalized skill development platform, which will be available with a Pro subscription ($9/month). I'm sharing this with the HN community to get your thoughts and feedback. I'm especially interested in how the AI performs in generating useful content and any suggestions on improving the tool. Please let me know what you think! https://ift.tt/RvwohdZ December 27, 2024 at 04:12AM

Show HN: Quixotic – a tool for wasting bot and LLM scraper time https://ift.tt/1MlXd8E

Show HN: Quixotic – a tool for wasting bot and LLM scraper time I get a lot of bot traffic, most of which doesn't appear to respect robots.txt, so I made a tool to easily rewrite my content to serve to these bots instead. It consists of two components: quixotic - a command line tool that is static-site friendly to generate a copy of a website with some of the words replaced using a Markov generator. linkmaze - a web server that I can send the worst bots to. It generates 100% Markov content on the fly and with random links that also refer to linkmaze content. https://ift.tt/1R64qFb December 26, 2024 at 11:50PM

Show HN: I've made a Monte-Carlo raytracer for glTF scenes in WebGPU This is a GPU "software" raytracer (i.e. using manual ray-scene intersections and not RTX) written using the WebGPU API that renders glTF scenes. It supports many materials, textures, material & normal mapping, and heavily relies on multiple importance sampling to speed up convergence. https://ift.tt/tJC4SGx December 26, 2024 at 10:54PM

Show HN: Map of YC Startups https://ift.tt/e79L05C

Show HN: Map of YC Startups Hey Everybody! Hope you had a merry christmas Today I had a bit of fun with Claude. Started by scraping YC's startups list, then ran them through OpenAI's embedding service, then UMAP'd the embedding to reduce the dimension to just two coordinates and then just forced Claude to write React that would compile to visualize that. I had fun and I think it's interesting, so take a look! Also note that you won't be able to zoom on mobile (found about this Plotly limitation way too late). If there's interest I can fix this issue by changing plotting libs tomorrow :) Merry christmas https://ift.tt/jn7fCbh December 26, 2024 at 04:07AM

Show HN: SMS Reminders for Birthdays https://ift.tt/riypFNh

Show HN: SMS Reminders for Birthdays I built a simple service that sends SMS reminders for birthdays. Why? I kept missing birthdays, even with calendar apps. This single-purpose tool is simple and (so far) reliable. Since my texting inbox has a far better signal-to-noise ratio than email or calendar events, it ensures I never miss an important date. Facebook used to serve the same purpose, but it's a dying social graph for me. https://ift.tt/n70lGeU December 25, 2024 at 11:52PM

Show HN: Minimalist, text only search engine with prefixes to play with https://ift.tt/Q1YNtX6

Show HN: Minimalist, text only search engine with prefixes to play with I made this classic looking text only search engine(sorry if that's overexaggerating) where you can get concise and straightforward results with sources. There are 5 prefixes right now. It is a prototype kinda thing right now. I am busy for my upcoming exams. So, I would appreciate if anyone is interested to contribute. I am currently using Gemini for this project. If anyone can implement better api's and improve code and the features it would be great help. It's generating fake source links right now, the search is slow, prefixes like weather and time needs to be fixed using api's related to weather and time cause gemini can't give the current time and weather of any place. Pdf resources its giving are fake and do not exist. Let me know what more I can add here. Or directly contribute by yourself. https://ift.tt/t6MlpGb December 25, 2024 at 12:56AM

Show HN: Otto-m8 – A low code AI/ML API deployment Platform https://ift.tt/JhLXICQ

Show HN: Otto-m8 – A low code AI/ML API deployment Platform Hi all, so I've been working on this low to no code platform that allows you to spin up deep learning workloads(I'm talking LLM's, Huggingface models, etc), interconnect a bunch of them, and deploy them as API's. The idea essentially came up early in September, when experimenting with combining a Huggingface based BERT model with an LLM at work, and I realized it would be cool if I could do that instantly(especially since it was a prototype). At the time, I was considering a platform that could essentially help you train deep learning models without any code. It was my observation that much of the code required to train or even run inference on HF models have matured significantly. But before I solved that problem, I wanted to solve inference. Initially inspired by n8n and AWS Cloudformation, I built out otto-m8 (translates to automate). Given a json payload that lists out all the resources, and how each model is interconnected, launch it as one-off API the user can query. And thanks to Reactflow, the UI was just something I couldn't just not implement. And as I built it out, I did not want to miss out on the LLM and Agent bit. With otto-m8, today, you can launch complex workflows by interconnecting HF models and LLM's(currently it supports OpenAI and Ollama only). But I like to see it being more than that. At the core, every workflow is an input process output model. Inputs get processed and there's an output. Therefore, with the way things are setup, one can integrate almost anything and make it interconnectable. Project Link: https://ift.tt/ITH2QiE Let me know what you guys think. I really would love feedback! https://ift.tt/ITH2QiE December 22, 2024 at 03:09AM

Show HN: I built this website about Sikh History and don't know how code works https://ift.tt/TJdH7LM

Show HN: I built this website about Sikh History and don't know how code works I've been learning about Sikhism and Sikh history recently and, despite having Game of Thrones level drama, I found the resources really lacking and nowhere piecing it all together. I work in a developer adjacent role (ok, I'm a Product Manager) but despite working with software engineers every day I don't really get coding. I see a lot of stuff online about the death of software engineers and wanted to challenge myself to see if I could create something myself. I've been using the free tier of Anthropic's Claude AI, deployed on the free Vercel tier, spent $10 on the domain but not a penny more on anything else. It's super basic but felt good to make something myself and I learned a lot. I'd brick it at the idea of adding anything complex (or even being asked how it all works together) so I'm sure developers are safe for a while yet! https://ift.tt/KzvT6MN December 23, 2024 at 10:31AM

Show HN: Skybear.net – A managed platform automating Synthetic HTTP API testing https://ift.tt/hA1Egno

Show HN: Skybear.net – A managed platform automating Synthetic HTTP API testing Hey folks, I am finally posting a Show HN post for a project I have been working on for several months now, and it's in a state where I already get a lot of value myself, so I am happy to share broadly. The pitch line is: "Skybear.NET is a managed platform automating Synthetic HTTP API testing." At the moment, the main source file format supported for your API tests are Hurl.dev files [1]. Hurl is a CLI tool wrapping `curl` and it's really awesome. At least check that out :) I am not affiliated directly with the Hurl CLI tool, and the platform I am building provides full Hurl compatibility. I have been using Hurl for a few years now [2], and use it for my API testing, for orchestrating a bunch of HTTP APIs, and in general whenever I need to do anything with HTTP requests, I reach for Hurl. You can try without signup the basic execution feature with the free Open Editor [3], but for full functionality (retaining responses and cron triggers) you need a signed in account, even free. The Skybear.NET platform: 1. Has Hurl Compatibility, so take your local scripts and run them on the cloud as well. No changes needed. 2. Provides managed infrastructure for authoring, storing, and most importantly executing your Hurl scripts, that automatically scales to handle as many script runs as you need. 3. Generates detailed reports from your tests execution, automatically persisting requests and response bodies for introspection in the future, and with automatic insights coming up soon. 4. Supports multiple ways of triggering execution of your scripts, including periodic executions, and on-demand HTTP triggers enabling integration with your CICD pipelines. Most importantly, it eliminates excessive per-request/per-step/per-check charges, leading to substantial cost-savings for complex multi-step API tests covering complete user-journeys. I consider a "script project run" to be the main unit in my pricing, which includes execution of all the source files of the script project, which can be tens or hundreds of requests. I am starting to document some of the architecture of the platform as well [4], but in a nutshell, all your data is encrypted inside the application before stored on AWS (S3, DynamoDB, also encrypting at rest) [5], the control plane runs on Hetzner and AWS EC2, and the execution servers running your scripts run on Fly and soon on AWS EC2 (for some plans). Future plans depend a lot on feedback from users. I already have a long list of things I personally want to have, but as more users start using I would like to see user needs influencing the roadmap more. Some upcoming features: 1. Insights and metric graphs for historical tracking of your tests (per project, per file, per request URL). 2. Automatic generation of tests based on OpenAPI schemas, HAR files, etc. 3. Export API of all the data and reports for your own consumption. 4. OTEL traces generated per script run, exportable and sent to APM products. Thank you, and I hope you find it interesting too!
