Submarius began as a diving conditions dashboard but evolved to address the lack of a water clarity API. The creator developed a state-augmented ensemble kalman filter to calculate water clarity, seeking feedback from the HN community on potential improvements. The project faces challenges with messy satellite data, including cloud misinterpretations and shallow reef reflections.

A 9th grade student from India asks questions about the Second Law of Thermodynamics and General Relativity, specifically whether entropy prevents time from running backwards and if time dilation relates to atomic motion in strong gravity. The student clarifies they are not proposing new theories but seeking to identify flaws in their understanding.

MLJAR Studio is a desktop application that uses natural language to generate Python code for data analysis, saving workflows as reproducible Jupyter notebooks. It supports local execution, multiple data formats, and integrates with various databases and AI models like Ollama or OpenAI. Priced at $199 with a 7-day trial, it aims to bridge the gap between manual Jupyter Notebooks and cloud-based AI tools.

The article introduces a live dashboard for real-time sun and moon visualization using NASA footage, hosted at lumara-space.app. The tool is highlighted on Hacker News with 14 points and one comment.

Browser Harness is a new tool that grants LLMs maximum freedom to perform browser tasks by removing restrictive frameworks. It uses Chrome's CDP websocket with self-correction and dynamic tool creation, enabling LLMs to handle edge cases like file downloads and cross-origin iframes autonomously. Examples include playing Stockfish, setting Tetris records, and generating JavaScript to draw a heart.

The article discusses the integration of SPICE simulation with an oscilloscope using MCP servers and Claude Code for verification, enabling a feedback loop between simulated and real-world hardware. The author built the servers to bridge simulation and physical hardware testing.
