YHK - yet another hacker news clone

Author here. I'm Korean, and I have cochlear implants in both ears, which I received in a clinical trial in 2025. No one could tell me what I actually hear, so between 11 October and 4 November 2026 I ran seven psychophysical tests on myself (10,992 trials), using browser test apps that Claude built for me. I'm an amateur, so there are surely mistakes, and corrections are very welcome.

All trial-level data, the analysis code and Lean 4 checks of the apps' logic are on GitHub (non-commercial licenses): https://github.com/mi-rae-lab/ci-psychophysics-data

I do not speak English. The page was translated with Claude, and I will use AI to read and answer replies, so my answers may be slow.

This is my first time visiting Hacker News, and my first post here. I don't know the culture here well yet, but I deeply respect it and support it.

It is past 1 a.m. here in Korea and I am very tired, so I need to get some sleep. I will check back around 9:30 a.m. Korean time (00:30 UTC).

> I had the surgery at Samsung Medical Center

Given the quality of samsung fridges (so I’ve heard anyway), “Samsung medical center” gives me shivers. I hope an unexpected cloud update to add an AI assistant doesn’t silently disable your implants there.

Given how wide samsung is in electronics (and, well, everything) manufacturing, I wouldn’t be surprised if plenty of other hospitals are running samsung tech though
