In plain words
LLM Rescuer is a Ruby gem designed to address nil safety issues in Ruby code. It provides automatic handling of nil values through prediction mechanisms rather than traditional error handling. The tool targets Ruby developers working on projects where nil reference errors cause significant problems. It offers a different approach to nil safety by using inference to manage potentially null values in code execution.

This project is an experimental proof-of-concept developed for educational purposes and pure, unadulterated fun. It uses AI to dynamically handle runtime errors, which introduces unpredictable behavior and potential security risks that would make your security team cry. Never use this in production environments unless you enjoy explaining to your boss why the AI decided your user's name should be "🐱 Mr. Whiskers". In 1965, Tony Hoare invented the null reference and later called it his "billion-dollar mistake" . Well, we're here to fix it by potentially spending a billion dollars in OpenAI API tokens! 💸 Because clearly, the best way to solve a problem caused by the absence of a value is to…from github.com

LLM, a Rust Crate/CLI for CPU Inference of LLMs (LLaMA, GPT-NeoX, etc.)2023 · github.com · ▲45G'day, HN! I'm one of the maintainers of `llm`. I've been working alongside a trusty group of contributors to bring this project to life, and we're now at a point where we're ready to share it with the world. Large language models (LLMs) are taking the computing world by storm due to their emergent abilities that allow them to perform a wide variety of tasks, including translation, summarization, code generation, and even some degree of reasoning. However, the ecosystem around LLMs is still in its infancy, and it can be difficult to get started with these models. `llm` is a one-stop shop for…
LLM-Term – Simple Rust-based CLI assist tool2024 · github.com · ▲32Current AI-assisted CLI tools are often part of larger systems and work better on Linux. I built llm-term to address these. It's a Rust-based tool that compiles into a single binary file. You only need to download the binary, add it to your PATH, and configure your OpenAI key to get started. While llm-term offers an option for gpt-4o, it works great with gpt-4o-mini. So it's not costly. I appreciate any feedback or suggestions.

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
