Show HN: I built an AI-powered professional headshot generatorhttps://www.quickheadshots.comHello HN,I've created QuickHeadshots (https://www.quickheadshots.com), an AI-powered service that generates high-quality professional headshots from a few selfies.As a developer, I found existing solutions lacking in consistency and quality, so I decided to build my own. The app uses fine-tuned stable diffusion models to create realistic, professional-looking headshots suitable for LinkedIn profiles, company websites, or any other professional use. This is the result of a lot of experimentation around this to get to a decent quality. The goal has been quality and faithfulness to uploaded images.I'd love to get your feedback on the user experience, technical suggestions or any other aspects of the project. What do you think about the current state of AI-generated images for professional use? Are there any features you'd like to see added?I'm also happy to answer any questions.

NASA: Life Signs Could Survive Near Surfaces of Enceladus and Europahttps://science.nasa.gov/science-research/planetary-science/astrobiology/nasa-life-signs-could-survive-near-surfaces-of-enceladus-and-europa/Europa, a moon of Jupiter, and Enceladus, a moon of Saturn, have evidence of oceans beneath their ice crusts. A NASA experiment suggests that if these oceans support life, signatures of that life in the form of organic molecules (e.g. amino acids, nucleic acids, etc.) could survive just under the surface ice despite the harsh […]

Show HN: Auto-generate a custom, developer-first playground for your LLM apphttps://news.ycombinator.com/item?id=40826557Hi everyone -We’re the team at Inductor (https://inductor.ai), where we’re building the tools that developers need to build production-ready LLM apps and product features – far more quickly, easily, and systematically. We’re super-excited to share a new capability that we’ve just built: Custom Playgrounds.We built Custom Playgrounds because it’s important to be able to interactively experiment with an LLM app or product feature as you’re building it, and share your work in order to collaborate – but, today, this is too often cumbersome to do.Custom Playgrounds solve this problem by providing a developer-first way to auto-generate and instantly share a playground running directly against your code and environment, with a single Inductor CLI command: $ pip install inductor $ inductor playground my.module:my_function where “my.module:my_function” is the fully qualified name of a Python function that is the entrypoint to your LLM app. (No modifications to your code required!)Some highlight

Show HN: Sheet Copilot – Run tasks using GPT-4 in Google Sheetshttps://www.sheetcopilot.aiI've been building Google Sheets Add-Ons for around 3-4 years now, and working on Sheet Copilot (Formerly Formula God) for over a year.1. We started with using AI for formula generation and code execution in Google Sheets. 2. Then we built a chat interface for Google Sheets to analyse data and help with formulas.It never felt like we realised our initial vision, but now I feel we're a little closer.Sheet Copilot, can:- solve complex problems with formulas - format your sheets - visualise your data + add charts to your sheet - keep you updated every step of the wayYou can watch in real-time as it takes control of your spreadsheet, executes your tasks, fixes its own errors and guides you through its plan.It's also still fairly experimental and comes with its quirks, so we we're seeking as much feedback as possible! For that reason, we're releasing it free while it's in BETA, you just need to plug-in your OpenAI API key.Here's a demo video showing what it can do: https://video.wixstatic.c

New Shepard Returns to Flighthttps://www.spacescout.info/2023/12/ns24-returns-to-flight/After over a year of waiting, New Shepard has returned to flight. Following a scrubbed launch on the 18th, New Shepard cleared the tower flying the NS-24 mission on December 19th at 10:43 AM. The flight carried 33 experimental payloads, ranging from student projects to NASA-funded research, to the edge of space and back again. Both the Propulsion Module and Crew Capsule returned to the ground safely, and while there was no crew riding on this flight, the successful mission paves the way for a return to crewed flights in the near future.

Ask HN: How do you adapt after early retirement?https://news.ycombinator.com/item?id=37630064I wonder how many people here have retired early and have found it hard to relate people who are still working?I have had three different jobs since the start of COVID-19 due to the ebbs and flows of the tech industry and economy. The transition to working remotely was also difficult for me, and I wanted to return to the office. That sometimes requires moving, and this is challenging when both spouses are working.Around 18 months ago my spouse and I agreed that we would experiment with her retiring. Her new "job" would be taking a larger proportion of the household chores, and helping me with administrative chores I used to do alone like budgeting, financial planning, house repairs. We don't have children so she has time to pursue her hobbies nearly full time.In some ways this has been great. She regularly says she feels lucky to have the opportunity to do this. She has more time and mental resources to face her chronic health conditions and making progress that seemed impossible befor

Show HN: Breathwork App for Endurance Athleteshttps://breathic.comHi,I had a problem of how to get into a proper shape again after quitting smoking after 17 years, where lungs of mine were the main bottleneck. I was therefore inclined to find a solution that would help me to systematically improve my breathing pace, but since I couldn't find anything related to it, I therefore decided to solve it myself. Being a designer while also having skills of a full-stack developer, I decided to learn Swift and use Apple Watch to design one.In essence, the app is rather similar to how Strava works on Apple Watch: you start your workout session, go through with it, and then have it saved for further analysis. The real difference is that you also set your breathing pace, which will translate your heart rate to breath rate and give relevant haptic cues when to breath in and out.Since I had to build a sampler to WatchOS, I also experimented with trying the app to generate background music that would be synced to both heart and breathing rates.

Show HN: WhatsApp-Llama: A clone of yourself from your WhatsApp conversationshttps://github.com/Ads-cmu/WhatsApp-LlamaHello HN!I've been thinking about the idea of a LLM thats a clone of me - instead of generating replies to be a helpful assistant, it generates replies that are exactly like mine. The concept's appeared in fiction numerous times (the talking paintings in Harry Potter that mimic the person painted, the clones in The Prestige), and I think with LLMs, there might actually be a possibility of us doing something like this!I've just released a fork of the facebookresearch/llama-recipes which allows you to fine-tune a Llama model on your personal WhatsApp conversations. This adaptation can train the model (using QLoRA) to respond in a way that's eerily similar to your own texting style.What I've figured out so far:Quick Learning: The model quickly adapts to personal nuances, emoji usage, and phrases that you use. I've trained just 1 epoch on a P100 GPU using QLoRA and 4 bit quantization, and its already captured my mannerismsTuring Tests: As an experiment, I asked my friends to ask me 3 quest
