Show HN: A library for execing Python code safely using WASM https://bit.ly/3CCgGWW

Show HN: A library for `exec`ing Python code safely using WASM Inspired by Simon Willison's blog post that was catalyzed by this HN post: https://bit.ly/46gIM80 wasm_exec is a Wasm-powered, sandboxed implementation of exec() for safely running dynamic Python code There are number of use-cases emerging that require arbitrary code execution, often code that is generated by LLMs (Large Language Models) like ChatGPT. This can enable some really cool functionality - like generative BI or website generation - but also introduce a massive security flaw if implemented via eval() or exec(). This is because arbitrary code can be executed using these methods. In a worst case scenario, exec'ing arbitrary code could enable some to rm -rf / your entire server! This library intends to provide a secure method of executing arbitrary Python code to empower LLM-based code generation. This was originally intended to be a direct PR to Langchain but given that the problems with exec() extend to the entire Python ecosystem, it was decided that it would be better as a standalone package. Given the love for Wasm on HN, I thought some folks might be interested,and I'd love additional feedback or contributions to the code base. https://bit.ly/3NhyYSy June 21, 2023 at 01:44AM

Show HN: AfterZhev A Graphical RPG for Arduino in AVR Assembly https://bit.ly/43PGqva

Show HN: AfterZhev – A Graphical RPG for Arduino in AVR Assembly For the last year I've been working on a small RPG, called "AfterZhev", that runs on a single ATmega2560 plus some passive components. The game runs at 60 FPS on a stock 16 MHz ATmega2560, so it's Arduino Mega2560 compatible, and generates a 60 Hz 640x480 VGA video output, with an effective resolution of 120x66 pixels. It also generates 8-bit sound. AfterZhev was written entirely in AVR assembly. AfterZhev - I think! - is the only graphical RPG that runs on an 8-bit Atmel chip. I'd like to be wrong about that, though. As the world's official best player, I can beat the game in under three minutes, but it'll probably take an hour or so to complete. Let me know what you think! Writeup: https://bit.ly/3Xfetug Source code: https://bit.ly/3XebvpT https://bit.ly/3NltDtp June 20, 2023 at 10:35PM

Show HN: Reproducing TikTok with Django Ninja and React Native https://bit.ly/3PnraRW

Show HN: Reproducing TikTok with Django Ninja and React Native I am about to graduate from university this year, and I had an idea to create a mobile app similar to TikTok but for OnlyFans. Interestingly, the inspiration to replicate TikTok came from an episode of the Acquired Podcast discussing Meituan. It seemed somewhat ironic to copy a Chinese app. I ran out of money to pay rent though, so I’m looking for jobs here in Sydney instead now. I want to keep working on this project in my spare time and would appreciate any feedback and particularly guidance for how to run an open-source project! https://bit.ly/46bG9nI June 20, 2023 at 02:19AM

Show HN: Global Pomodoro every 30 minutes https://bit.ly/3Phm21D

Show HN: Global Pomodoro every 30 minutes I love using the Pomodoro technique with my friends. We each share what we want to accomplish in 25 minutes, work together, and then take a 5-minute break to discuss our progress. Recently, I had an idea to take this concept to the next level. If you think about it, 25 + 5 = 30 minutes - the perfect amount of time for a global Pomodoro session to start every half hour. After several evenings of brainstorming and collaboration, I'm excited to introduce Pomodorr.io. This platform allows individuals from around the world to come together and work on their projects during these global Pomodoro sessions. So, meet Pomodorr.io. Every 30 minutes, a global pomodoro kicks off in the world. There is a general chat to feel the shoulder of remote colleagues in terms of efficiency. You can meet me and my friends there almost every day. https://bit.ly/44c328Z June 20, 2023 at 12:12AM

Show HN: Simulacra and Simulation Photography Project https://bit.ly/3NBu7N7

Show HN: Simulacra and Simulation” Photography Project Simulacra and Simulation is a conceptual photography project that is meant to explore what constitutes reality in an image. First, I ask ChatGPT to create a detailed description of a famous photograph. Second, I provide that description to Midjourney, which creates a flawed, but usually recognizable interpretation of the original photograph. Third, I capture my computer screen, where the Midjourney image is visible, with a medium format film camera. Fourth, I hand develop and print the resulting image, which is now very much a real photograph of a facsimile of a real photograph. https://bit.ly/3Pq91D3 June 19, 2023 at 07:04PM

Show HN: HN recommend A recommendation engine for Hacker News https://bit.ly/468R3e3

Show HN: HN recommend – A recommendation engine for Hacker News Hi! I’m Julien and I built a recommendation engine for Hacker News. I feel like this website is a gold mine. Every day, I find some very interesting stories about a topic. And sometimes, I want to find other stories covering that same topic but I can’t. Hacker News has years of history of awesome discussion and ressources. Unfortunately, I think HN Algolia isn’t helpful in searching these old threads. As a student, I want to learn a lot from this website. This is why I created HN Recommend. Input a sentence or the URL of an article, and get the most popular and similar posts from Hacker News. About the technical details, I've computed the embeddings of over 100,000 articles from HN and indexed it using Faiss. I made a blog post for a deeper explanation.

Show HN: I recorded a video course to let anyone learn Math bottom-up This course was intended for ages 7 and up, including adults. I really tried to make the material accessible to everyone, and hopefully not be too boring, while it establishes a solid foundation for learning anything else. If you do watch it, let me know if it is helpful in getting a solid foundation! My background: Before I got full-time into software development, I was doing a Ph. D in math at NYU. I thought YouTube needed something like this. https://www.youtube.com/@thinkingmathematically June 18, 2023 at 04:08PM
