Vibe-coded a web app for checking irregular guitar tunings kngwyu.github.io/guitar-tunin... So far I'm only using it for Open G but maybe useful for sonic youth like weird tunings? I feel like I should make use of more ChatGPT tokens not to waste my money but I rarely want something new 🙄

Guitar Tuning Tool
Select a guitar tuning and highlight notes in your selected scale on the fretboard. Customize individual strings and note selections.

For me it took a while to admit that I'm interested in reinforcement learning but not that excited about robots (or... Physical AI?)

From the Wikipedia article, the ancestor of whales lived in northern India. So why did they happen to live in the sea? 🤔

It's really tiring for me to continue applying for positions for which I will be selected with < 10 % prob... (optimistically says) I really want to come back to 'research' now 😭

I'm gradually understanding the benefit of evolutionary game theory, but still, I don't have a clever idea how to respond to a reviewer's comment like "Your evolutionary simulation is too original and does not have much connection to existing literature like evolutionary game theory" 🤔

Isn't it a good quote? > It (evolutionary psychiatry) instead provides a framework that can integrate knowledge from other basic sciences. From onlinelibrary.wiley.com/doi/full/10....

I just noticed that only 11 'Complex Systems' papers got accepted to GECCO 2026 (and mine is one of these) Does this mean most researchers aim at ALIFE? 🤔 Or the world may not have many 'complex systems' researchers...

I finally stopped worrying about my academic carrer because I believe I would have nothing to do but research after every possible job got replaced by AI. Then AI will assign research budget based on our proposal...... Not sure I should use AI to write the research proposal for AI though

Sakana AI used AI to support an alt-right story that China is manipulating Japanese SNS with lots of bots...😅 www.yomiuri.co.jp/politics/202... They say there's a rapid increase in tweet numbers from possibly Chinese accounts, but was it really more 'influential' than Japanese bots?

Fear is a critical brain function that enables us to learn to avoid danger via reinforcement learning (RL). While many researchers have argued that fear has evolved to escape predators, how varying pr...

I'm seriously thinking about how we should frame and deal with 'AI for war' risk. Anthropic did something but I feel like academia should do more. People say 'no way to avoid that' but if no one objects the situation might become worse.
