Show HN: A library for execing Python code safely using WASM https://ift.tt/UeXNT01

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://ift.tt/olbRmI7 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://ift.tt/lxpq8bm June 21, 2023 at 06:14AM

Show HN: AfterZhev A Graphical RPG for Arduino in AVR Assembly https://ift.tt/hjJ2WRv

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://ift.tt/G21dymp Source code: https://ift.tt/w0chrdx https://ift.tt/wFCP0J1 June 21, 2023 at 03:05AM

Show HN: pg-primer - Beginner's guide to administering/managing PostgreSQL I created this small guide for people starting with postgresql. I added some queries I commonly used as well. Any feedback? https://ift.tt/1TZJC6h June 21, 2023 at 01:06AM

Show HN: Autolabel a Python library to label and enrich text data with LLMs https://ift.tt/p8dIxVt

Show HN: Autolabel, a Python library to label and enrich text data with LLMs Hi HN! I'm excited to share Autolabel, an open-source Python library to label and enrich text datasets with any Large Language Model (LLM) of your choice. We built Autolabel because access to clean, labeled data is a huge bottleneck for most ML/data science teams. The most capable LLMs are able to label data with high accuracy, and at a fraction of the cost and time compared to manual labeling. With Autolabel, you can leverage LLMs to label any text dataset with <5 lines of code. We’re eager for your feedback! https://github.com/refuel-ai/autolabel June 21, 2023 at 12:56AM

Show HN: Reproducing TikTok with Django Ninja and React Native https://ift.tt/fjWLmK4

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://ift.tt/TxIAPtq June 20, 2023 at 06:49AM

Show HN: Global Pomodoro every 30 minutes https://ift.tt/7gp5Vyz

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://pomodorr.io June 20, 2023 at 04:42AM
