I suspect AI company want improved efficiencies and developing a framework that can be applied in determining the minimal-energy, maximal-efficiency architecture for ai models. Calculating the precise limits, like a Cognitive Event Horizon, where a model becomes so complicated it literally costs more energy to run than the knowledge it provides, and the Semantic Horizon, where it simply gets too complex to be accurate, etc. Lots of cool implications such as around a fundamental mathematical maximum learning rate which results in trying to get anywhere close to that that by doing stuff like aggressively filtering of the data.

I'm building a coding agent, named VT Code [0]. VT Code is a Rust-based terminal coding agent with semantic code intelligence via Tree-sitter. Supports multiple LLM providers with automatic failover and efficient context management. Support OpenAI, Anthropic, Google Gemini, xAI, DeepSeek, OpenRouter, Z.AI, Moonshot AI, MiniMax, and Ollama (local & Cloud). Agent Client Protocol and Model Context Protocol fully support. VT Code supports a rich set of configuration options, with preferences stored in vtcode.toml. Has both Visual Studio Code and Open VSX extensions so that you can install in VS Code or Cursor, Windsurf, Eclipse.

I've been building it for several months now and enjoy the learning process, I also wrote a blog post and learnt a ton about terminal, ANSI processing. The learning has been immense for me, I now have working knowledge of ANSI escape codes, grapheme clusters, terminal emulators, Unicode normalization, VT protocols, PTY sessions, and filesystem operations, all the low-level details I would have never think about until I were implementing them.

Built a local-first Kanban board with Tauri (Rust + Svelte) after getting frustrated with SaaS tools and basic offline options. Stores data in JSON files you control, full keyboard-first UX, parent/child tasks, release management, and it's blazingly fast with localStorage + background sync. No telemetry, purely local. Curious what others prioritize in personal task tools. Seems like there's a gap between "todo.txt" simplicity and Jira complexity.

Slowly but surely:

- A learning tool in Python for Arrays and Algorithms

- A prototype agent-based configuration management system in Perl

- Trying to reinstall Arch Linux on a laptop the second time around (lost my install notes :D)

Mostly doing all of it for learning purposes.

I'm making an app for self-tracking. Combining elements from habit trackers, health logging and journaling. Built for rich customization and local-first. Want to be free of rigid structures of many existing apps while providing a better UX / usability than using a spreadhsheet.
