TOON (Token-Oriented Object Notation) is open-source data serialization format that was publicly released just days ago. It is specifically engineered for the AI/LLM era: its single goal is to transmit the same structured data as JSON to large language models while using dramatically fewer tokens.

Today I'm preparing materials and a demonstration for the following tool ,spec-kit, to explain next week.
I've muttered about it here and there, but I personally think this tool itself is excellent, as it's garnering attention in many places.

When conducting hiring interviews, the most important consideration is not just an individual's potential, but whether they will create synergy and enhance the team's overall strength when they join as a member.

The skepticism about whether current AI justifies the capital spent is fair. Many models are still more promise than profit. Yet, the underlying tech is evolving fast, and breakthroughs in efficiency or new applications could reignite growth.

Today's my thought:
Pascal’s line is a banger because it nails the point: our strength isn’t muscle, it’s thinking. If we outsource that to “vibe-coding,” we end up as prompt routers who can’t debug our way out of a paper bag.

There has been some talk about OpenAI employees working 80 hours a week, but this is not surprising at all. With the rise of AI, my own working hours have increased even more than before. That's how much speed and density are required in this day and age.

This is my personal view on Vibe coding.
I want non-engineers to enjoy Vibe coding to realize your ideas, not for real-engineers.
I believe this is the ideal of GutHub, which was discussed at last year's GitHub Universe about a future where 1 billion people will be developers.

As I have said in various scenes, Vibe coding, which is still being implemented by many people, is AI-assisted development. I don't think it can be called AI-driven development yet.
