Show HN: PurePlates – A Recipe Scraping iOS App Hey Everyone! This is my first post on Hacker News, and I wanted to share my project with you! From a young age, I dreamed of becoming a chef, but life took me down the path of software engineering instead. Nevertheless, my passion for creating delicious meals has always remained close to my heart. This journey led me to seek out recipes to enhance my cooking skills, but I often found myself frustrated by the websites I encountered—ads everywhere, walls of text, and recipes that were difficult to follow. That’s where PurePlates comes in. PurePlates allows users to share a recipe through their mobile browser or simply copy and paste the URL directly into the app. In an instant, you receive a scraped recipe that includes instructions, ingredients, and any available nutrition information. You can easily start cooking and follow along step by step, making the process much more enjoyable. Plus, if you find a recipe you love, you can add it to ...

Show HN: I Built a Multimodel AI Chatbot to Avoid Having FOMO on the Best Models Hi HN, I built ChatOne while working on a project and constantly switching between AI models like GPT-4 and newer ones like Claude 3.5. I kept wondering if I was missing out on better answers, so I created ChatOne to get responses from multiple models at once and compare them easily. -Teddy https://chatone.io September 29, 2024 at 09:38PM

Show HN: I Made a Site for Designers to Gen Great Patterns Quickly, No Headaches It was a crisp autumn evening when I found myself burning the midnight oil, yet again. As a graphic designer, I was knee-deep in a project that required intricate patterns for a client's new product line. The clock ticked mercilessly as I struggled with complex design software, trying to bring my vision to life. That's when it hit me – why couldn't I just tell a computer what I wanted and have it create the pattern for me? Why did I need to wrestle with technical jargon and complicated prompts when I had a clear picture in my mind? This revelation sparked a journey that would consume the next eight months of my life. I dove headfirst into the world of AI, determined to create a tool that could understand designers' needs in plain English. It wasn't easy – there were countless late nights, gallons of coffee, and moments of doubt. I experimented with various AI models, eventually settling...

Show HN: GitHub Repo Visualizer Using D3 I built this as part of my quest to properly learn data visualization. The code is the easy part! Some lessons learned: - personal verification of the the general truth that pie charts are tough! and the returns are not great for the effort due to people's difficulties perceiving angles - may not use "vanilla" d3 with no React. was difficult to adapt for mobile - the GitHub API provides fairly standardized responses so building dynamic charts wasn't too bad. But when working with streaming data (say Kafka) I can see this getting interesting... schema registry should help but creating a view into the data with a lookback would be interesting with d3, done it with altair before. https://ift.tt/nudoGVS September 24, 2024 at 11:17PM

Show HN: Hoodmaps Meets 4chan I made this as a pair programming exercise with o1-preview. o1 did most of the heavy lifting, through high level prompts, but eventually I needed to diverge from it to get to completion. My initial prompt was: --- I'm making a web app: It's like 4chan, but each thread starts with a gps coordinate. People can only post text and images. I want to build it with flask and sqlalchemy. I want just the backend and data model that supports these threads, anonymous users, and users that can register a permanent username. Write as much of it as you can for me. --- This produced a fully scaffolded Flask app running on sqlite. After that, it took a few (casual) evenings of iteration to dockerize everything, implement postgres instead of sqlite, and use a bucket for storage. On my own, this would have easily taken me 10x the time. https://mapchan.com September 23, 2024 at 06:39PM

Show HN: A YouTube videos course generator REPOST! (to get more feedback from HN) An exciting aspect of what I'm working on is that users can create their own playlists. For example, you can provide a description of what you're learning, such as a lesson title, and the pipeline will create a youtube playlist. Since the content is highly customized, it will be relevant and high-quality, matching current lessons or lectures in school or university. I'm trying to find a product structure that users will find valuable and effective. The web app is completely free to use right now as I figure out the best model. https://ift.tt/KsaXEJ8 September 12, 2024 at 10:35PM

Show HN: Tune LLaMa3.1 on Google Cloud TPUs Hey HN, we wanted to share our repo where we fine-tuned Llama 3.1 on Google TPUs. We’re building AI infra to fine-tune and serve LLMs on non-NVIDIA GPUs (TPUs, Trainium, AMD GPUs). The problem: Right now, 90% of LLM workloads run on NVIDIA GPUs, but there are equally powerful and more cost-effective alternatives out there. For example, training and serving Llama 3.1 on Google TPUs is about 30% cheaper than NVIDIA GPUs. But developer tooling for non-NVIDIA chipsets is lacking. We felt this pain ourselves. We initially tried using PyTorch XLA to train Llama 3.1 on TPUs, but it was rough: xla integration with pytorch is clunky, missing libraries (bitsandbytes didn't work), and cryptic HuggingFace errors. We then took a different route and translated Llama 3.1 from PyTorch to JAX. Now, it’s running smoothly on TPUs! We still have challenges ahead, there is no good LoRA library in JAX, but this feels like the right path forward. Here's a d...

Show HN: Anthropic React Native Client I recently published a new package on npm that brings the Anthropic APIs to React Native without polyfills. The library supports chat streaming and normal chat completions. The goal of the library is to follow the Node SDK wherever possible while taking advantage of React Native SSE for streaming where the Anthropic Node SDK does not work.

Show HN: An open-source implementation of AlphaFold3 Hi HN - we’re the founders of Ligo Biosciences and are excited to share an open-source implementation of AlphaFold3, the frontier model for protein structure prediction. Google DeepMind and their new startup Isomorphic Labs, are expanding into drug discovery. They developed AlphaFold3 as their model to accelerate drug discovery and create demand from big pharma. They already signed Novartis and Eli Lilly for $3 billion - Google’s becoming a pharma company! ( https://ift.tt/anHguU0... ) AlphaFold3 is a biomolecular structure prediction model that can do three main things: (1) Predict the structure of proteins; (2) Predict the structure of drug-protein interactions; (3) Predict nucleic acid - protein complex structure. AlphaFold3 is incredibly important for science because it vastly accelerates the mapping of protein structures. It takes one PhD student their entire PhD to do one structure. With AlphaFold3, you get a prediction in minu...

Show HN: I made a REST based alternative to GraphQL for PostgreSQL Hi guys! I have had a love-hate relationship with GraphQL for a while and decided to build my own tool as a side project! It's a REST-based API generator that you can use to build and deploy on top of PostgreSQL. I am currently working on a GitHub integration so you can push your API directly to GitHub and deploy on your own infrastructure. The plan is to stabilize the features by December and then to open-source it. It's completely free to use since it's in beta, and I would appreciate any feedback I can get.

Show HN: A YouTube videos course generator An exciting aspect of what I'm working on is that users can create their own playlists. For example, you can provide an outline of what you're learning, such as notes from your professor or any other structure, and the pipeline will create a course tailored to that. Since the content is highly customized, it will be relevant and high-quality, matching current lessons or lectures in school or university. Initially, the pipeline also generated some teaching content using AI, but due to the risk of AI hallucinations, I'm planning to pivot away from that. The new focus will be on curating YouTube videos relevant to each subject, so the courses will consist entirely of expert-created content from YouTube. This approach avoids copyright issues entirely. I'm still in the process of updating the code to implement these changes. The reason I'm posting this is to get feedback on how it sounds to you as learner. I'd love to hear y...

Show HN: Bin-graph: Visualize binary files This program provides a simple way of visualizing the different regions of a binary file. Written in C, depends only on libpng. Currently (commit 1dd42e3) it is able to generate PNG images that represent various aspects of the binary: - Grayscale: Byte values, 00..FF. - Ascii: Printability of each byte. - Entropy: Of a "block", changed with --block-size. - Histogram: Bar graph of the byte frequencies. - Bigrams: Each point is determined by a pair of bytes. - Dotplot: Measure self-similarity. Image width/height is N^2. In the future, I plan on adding an SDL version that allows the user to view a section of the file interactively (sections are currently supported with --offset-start and --offset-end).
