New top story on Hacker News: Show HN: A Raycast-compatible launcher for Linux

Show HN: A Raycast-compatible launcher for Linux 8 by ByteAtATime | 0 comments on Hacker News. Hey HN! I'm a huge fan of Raycast, but as a Linux user, I was always disappointed it wasn't available on my main OS. This summer, I decided to just build it myself. This project has the goal of being interoperable with Raycast itself, including a majority of the extensions. It's built with Tauri and Rust on the backend, with a Svelte frontend. The biggest challenge was getting it to run existing Raycast extensions, which required building a custom React renderer as well as making a custom API. I also wrote a quick post, which I hope to expand on in the future, about this project. You can find it here: https://ift.tt/yRsH5zx The project is still very rough, but I'm sharing it now to get any feedback you may have!

New top story on Hacker News: Show HN: RULER – Easily apply RL to any agent

Show HN: RULER – Easily apply RL to any agent 5 by kcorbitt | 0 comments on Hacker News. Hey HN, Kyle here, one of the co-founders of OpenPipe. Reinforcement learning is one of the best techniques for making agents more reliable, and has been widely adopted by frontier labs. However, adoption in the outside community has been slow because it's so hard to implement. One of the biggest challenges when adapting RL to a new task is the need for a task-specific "reward function" (way of measuring success). This is often difficult to define, and requires either high-quality labeled data and/or significant domain expertise to generate. RULER is a drop-in reward function that works across different tasks without any of that complexity. It works by showing N trajectories to an LLM judge and asking it to rank them relative to each other. This sidesteps the calibration issues that plague most LLM-as-judge approaches. Combined with GRPO (which only cares about relative scores with...
