Show HN: PFAS.report – Measure the forever chemicals in your blood via Quest
Hey HN<p>We made a site that let's anyone measure the forever chemicals in their blood with the gold standard LC-MS/MS blood serum test at Quest Diagnostics.<p>If you're a firefighter, plant worker, planning to become pregnant or just someone who lives in an area with contaminated drinking water, check it out.<p>I live in Santa Cruz. Here are my results:<p>My lab findings: <a href="https://res.cloudinary.com/mpsh87/image/upload/v1687923285/lab_results_redacted_final_e28vh4.pdf" rel="nofollow noreferrer">https://res.cloudinary.com/mpsh87/image/upload/v1687923285/l...</a><p>My total PFAS calculation: <a href="https://res.cloudinary.com/mpsh87/image/upload/v1687923482/pfas_report_calculator_ntal6v.png" rel="nofollow noreferrer">https://res.cloudinary.com/mpsh87/image/upload/v1687923482/p...</a><p>NASEM clinical recommendations based on Total PFAS: <a href="https://res.cloudinary.com/mpsh87/image/upload/c_scale,dpr_2.0,h_1200/v1687923501/NASEM_clinical_recommendations_stcvq9.jpg" rel="nofollow noreferrer">https://res.cloudinary.com/mpsh87/image/upload/c_scale,dpr_2...</a><p>The goal is to be under 2 ng/mL. I'm 10.86.<p>Honestly I was a bit surprised by my result and am currently deciding what to do next.<p>There's some research out of Australia indicating blood donation/phlebotomy is effective at removing it (<a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2790905" rel="nofollow noreferrer">https://jamanetwork.com/journals/jamanetworkopen/fullarticle...</a>) from the body. Fluorochemicals seem to bind to the albumin in the blood. I might try that.<p>Right now the site only works at Quest locations in California, but we're looking to expand to other states soon.<p>If you're local, the site is live and you can order the test right now. Results are currently taking between 11 and 18 days.<p>Thanks for reading my post.

Show HN: Mofi – Content-aware fill for audio to change a song to any duration
I worked on a web service that allows you to import a song and define a target length that the song will be shortened or lengthened to. It does this by analyzing the song and finding repeating audio patterns. This is helpful for making any song match a video or performance with a set duration. You can also specify areas of the song to prefer or avoid. An example is available here: <a href="https://mofi.loud.red/edit/8bd3fdf780f8c3927e41029f3b957f8a7ed96863" rel="nofollow noreferrer">https://mofi.loud.red/edit/8bd3fdf780f8c3927e41029f3b957f8a7...</a><p>The cool thing is that after the song is analyzed on the server, the client can recompute and preview the results completely client-side through an implementation that uses Web Workers and WebAssembly. The audio previewing uses Tone.js. I am thinking of writing up some more details about the implementation in the future.<p>I'm still working on a way to explain this easily, but I like the idea of carrying over the concept of content-aware fill from images to audio.<p>Please let me know if you have any comments or questions!

Show HN: Open-source shooter which made it to AC: Valhalla and Skydio drones
So just for fun, I wrote a complete multiplayer game in pure C++. I even wrote my own texture atlas packer, which is now used by Assassin's Creed, 2 scientific publications as well as a drone manufacturing company - each of these basically mentions the name of my game. There is even a claim that Unity patented some of the ECS ideas that originate from this project. See <a href="https://github.com/TeamHypersomnia/Hypersomnia#tech-highlights">https://github.com/TeamHypersomnia/Hypersomnia#tech-highligh...</a> for details.<p>By the way the game is pretty darn good. 10 people connected yesterday to test a new map:
<a href="https://www.youtube.com/watch?v=CHLPzZqANlM">https://www.youtube.com/watch?v=CHLPzZqANlM</a><p>It took me well over 10 years to code it all by hand, but the journey was truly worth it.

Show HN: WinGPT – AI assistant for Windows 3.1
Hey HN, I didn't want my Gateway 4DX2-66 from 1993 to be left out of the AI revolution, so I built an AI Assistant for Windows 3.1, based on the OpenAI API.<p>The most interesting parts of building this were:<p>- Getting TLS 1.2 and 1.3 working on Windows 3.1 so that WinGPT could directly connect to OpenAI's server without relying on a modern machine for TLS termination.<p>- Learning about the memory segmentation architecture on 16-bit Windows, including the difference between <i>far</i> and <i>near</i> pointers.<p>- Building the UI in plain C code with the Windows API and limited selection of controls in Windows 3.1.<p>You can check it out here and learn more about what it was like to build it: <a href="https://www.dialup.net/wingpt/" rel="nofollow noreferrer">https://www.dialup.net/wingpt/</a>

Show HN: Open-source resume builder and parser
Hi HN, I recently created and published an open-source resume builder as a weekend project. The idea came to me while I was mentoring students and noticing common mistakes they made in their resumes that I had also made in the past. I thought to build a tool to help people easily create a modern professional resume with built-in best practices to avoid those mistakes.<p>Top highlights of the resume builder are:<p>1. Real time UI update as you type<p>2. ATS friendly to top ATS platforms, e.g. Greenhouse, Lever<p>3. Privacy focus - no sign up is required and data is stored locally in browser that only users have access<p>4. Support import from existing resume PDF<p>The tool also includes a resume parser to help people test their existing resumes’ ATS readability if they might not be interested in using the builder. I also explained the parser algorithm in an article with interactive tables that might be an interesting read to see the steps and logics it uses (<a href="https://www.open-resume.com/resume-parser" rel="nofollow noreferrer">https://www.open-resume.com/resume-parser</a>).<p>I hope others might find this tool useful and I look forward to hearing any feedback the community has. Thanks all.<p>Home Page: <a href="https://open-resume.com" rel="nofollow noreferrer">https://open-resume.com</a><p>Github Repo: <a href="https://github.com/xitanggg/open-resume">https://github.com/xitanggg/open-resume</a><p>Product Hunt: <a href="https://producthunt.com/posts/openresume" rel="nofollow noreferrer">https://producthunt.com/posts/openresume</a>

Show HN: A gallery of graphs built with React and D3.js
Many JS libraries exist to build graphs on the web (Vega, chartJS, Plotly...).<p>They allow to make charts quickly.
But you lose flexibility: you're limited by the options they offer.<p>I just created a gallery with hundreds of graphs made with d3.js and React.
- Examples are split by graph types
- They all come with explanation and code sandboxes
- Gradual complexity to ease the learning curve<p>It took me ages to create this project! Feedback welcome!
