MCP Tools with Dependent Types: A Defold Editor Experiment

2025-08-18

This post details an experiment using a Large Language Model (LLM) within the Defold game editor. The author initially attempted to use Claude to directly manipulate Lua code, but faced low accuracy. The proposed solution involved using JSON Schemas to define tool inputs, but this ran into a limitation: the inability to implement dependent types within the Model-Code-Prompt (MCP) framework. This means the structure of tool input depends on runtime information. For example, editing 3D models requires different properties depending on the chosen material. The solution is a two-step process: the LLM selects a resource, the program looks up its data structure and constructs a JSON Schema; then, the LLM uses this schema to generate edits. The author suggests MCP should support dependent types to handle complex data more effectively.

Gemini Diffusion: The Speed Demon of Text Generation?

2025-05-22

Google's newly released Gemini Diffusion is wowing everyone with its speed; they even slowed down the demo to make it watchable. This article delves into why diffusion models are so fast, contrasting them with traditional autoregressive models (like GPT-4, Claude). Diffusion models generate the entire output at once, rather than token-by-token, enabling parallel generation of correct parts and faster speeds via reduced iterations. However, they're less efficient with long contexts and their reasoning capabilities remain questionable. While diffusion models might use transformers internally, their architecture makes their behavior fundamentally different from autoregressive models.

Transparency Paradox: How Openness Can Backfire and Reduce Public Trust in Science

A study reveals the 'transparency paradox': while transparency in science fosters trust, revealing bad news (like conflicts of interest or failed experiments) can decrease it. The root cause, argues the researcher, is the public's overly idealized view of science. The solution isn't hiding bad news, but improving science education and communication to present a more realistic picture—science isn't perfect, and scientists make mistakes. This fosters more realistic expectations and ultimately, increased trust.

Iberian Blackout: Was It Renewables' Fault?

Iberian Blackout: Was It Renewables' Fault?

A massive blackout hit Spain and Portugal in April 2024, affecting nearly 60 million people. While official investigations are ongoing, academics suggest several potential causes, including power plants sending excessively high voltage (overvoltages) to the transmission grid, and uneven reactive power distribution due to the distributed generation model of renewable energy (solar and wind). Traditional power plants provide inertia, stabilizing grid frequency, a characteristic lacking in renewables. The overvoltage issue highlights reactive power management, requiring adjustments to grid management rules to incentivize renewable energy plants to participate in reactive power balancing. Spain and Portugal's low interconnection capacity with neighboring countries also contributed to the blackout's widespread impact and duration. Future improvements in grid management rules, increased interconnection capacity, added energy storage, and AI-assisted grid operation are vital to prevent similar events.

Python's Curious Case of hash(-1) == hash(-2)

2025-01-10

A Reddit question about why `hash(-1) == hash(-2)` in Python sparked an investigation. By diving into the CPython source code, the author discovered that -1 is used as an error indicator in the `PyObject_Hash` function. Therefore, when the calculated hash is -1, it's converted to -2. This isn't a Python Easter egg, but rather a quirk of how CPython's C code handles errors.
