New best story on Hacker News: Show HN: StratusGFX, my open-source real-time 3D rendering engine

Show HN: StratusGFX, my open-source real-time 3D rendering engine 457 by ktstephano | 78 comments on Hacker News. It's been closed source for a long time while I worked on it on and off as a hobby research project, but yesterday the repo was made public for the first time under the MPL 2.0 license. A feature reel showing its capabilities can be found here: https://ift.tt/cS6IFkE... A technical breakdown of a single frame can be found here: https://ift.tt/dRonQ7X... It's still in a very beta state (bugs and instability expected), but I felt like it was a good time to make it public since a lot of its core features are mostly presentable. I plan to continue working on it in my spare time to try and improve the usability of the code. Two main use cases I could see for it: 1) People using it for educational purposes. 2) People integrating it into other more general purpose engines that they're working on since Stratus is primarily a rendering engine. Any extensions to the re

New best story on Hacker News: Launch HN: Play.ht (YC W23) – Generate and clone voices from 20 seconds of audio

Launch HN: Play.ht (YC W23) – Generate and clone voices from 20 seconds of audio 449 by hammadh | 455 comments on Hacker News. Hey HN, we are Mahmoud and Hammad, co-founders of Play.ht, a text-to-speech synthesis platform. We're building Large Language Speech Models across all languages with a focus on voice expressiveness and control. Today, we are excited to share beta access to our latest model, Parrot, that is capable of cloning any voice with a few seconds of audio and generating expressive speech from text. You can try it out here: https://ift.tt/7QtelB0 . And there are demo videos at https://www.youtube.com/watch?v=aL_hmxTLHiM and https://www.youtube.com/watch?v=fdEEoODd6Kk . The model also captures accents well and is able to speak in all English accents. Even more interesting, it can make non-English speakers speak English while preserving their original accent. Just upload a non-English speaker clip and try it yourself. Existing text to speech models either lack expres

New best story on Hacker News: Show HN: Apple Notes Liberator – Extract Notes.app Data and Save It as JSON

Show HN: Apple Notes Liberator – Extract Notes.app Data and Save It as JSON 527 by kello | 95 comments on Hacker News. Hey there! I just released the first version of a project I’ve been working on solves a very specific problem that perhaps only I have. I welcome any and all feedback, even if you just want to drop in to say that this is a hot piece of garbage!

New best story on Hacker News: Ask HN: How are you using GPT to be productive?

Ask HN: How are you using GPT to be productive? 579 by yosito | 703 comments on Hacker News. With GPT so hot in the news right now, and seeing lots of impressive demos, I'm curious to know, how are you actively using GPT to be productive in your daily workflow? And what tools are you using in tandem with GPT to make it more effective? Have you written your own tools, or do you use it in tandem with third party tools? I'd be particularly interested to hear how you use GPT to write or correct code beyond Copilot or asking ChatGPT about code in chat format. But I'm also interested in hearing about useful prompts that you use to increase your productivity.

New best story on Hacker News: Launch HN: Pynecone (YC W23) – Web Apps in Pure Python

Launch HN: Pynecone (YC W23) – Web Apps in Pure Python 532 by picklelo | 310 comments on Hacker News. Hi! We’re Nikhil and Alek, founders of Pynecone ( https://pynecone.io ), an open source framework to build web apps in pure Python. This can be anything from a small data science/internal app to a large multi-page web app. Once your app is built, you can deploy your app with a single command to our hosting service (coming soon!), or self-host with your preferred provider. Our Github is: https://ift.tt/8LNyREa Python is one of the most popular programming languages in the world. Webdev is one of the most popular applications of programming. So why can’t we make full-stack web apps using just Python? We worked in the AI/infra space and saw that even skilled engineers who wanted to make web apps but didn’t know traditional frontend tools like Javascript or React found it overwhelming and time consuming to learn. On the other hand, no code and low code solutions that save time in the de

New best story on Hacker News: Launch HN: Electric Air (YC W23) – Heat pump sold directly to homeowners

Launch HN: Electric Air (YC W23) – Heat pump sold directly to homeowners 571 by cmui | 527 comments on Hacker News. Hi HN! I’m Chris Mui, founder of Electric Air ( https://electricair.io ). We’re building a residential heat pump system. This will be an all-electric replacement for your home’s furnace and air conditioner that enables more centrally ducted installs, manages your indoor air quality, and saves you money on monthly energy bills. We also streamline purchase, finance and install by selling directly to homeowners. You can place a preorder today at https://electricair.io . Heat pumps work by using refrigerant and a compressor to move energy against a temperature gradient. If you put 1 kWh of energy into a heat pump, you get 3-5 kWh of heating in your home. But this isn’t breaking the laws of physics because heat pumps don’t make heat, they move it around. The extra 2-4kWh gets absorbed from the outdoors, even when it is cold outside. The low pressure refrigerant in the outdo

New best story on Hacker News: Show HN: BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT

Show HN: BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT 661 by genmon | 167 comments on Hacker News. I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I asked for a Dewey classification... and it worked. So I replaced a few days of fiddly work with 3 cents per inference and an overnight data run. My takeaway is that I'll be using LLMs as function call way more in the future. This isn't "genera
