Windows에서 한/영 전환할 때마다 키보드 종류 설정 → 재부팅 → 다시 풀려있음 → 또 재부팅... 이 무한루프 겪어보신 분 있을 겁니다. 이런 유틸들은 예전부터 많이 있었습니다. 그런데 막상 필요할 때 검색하면 잘 안 나오고 ("개똥도 약에 쓰려면 없다"고), 어쩌다 찾아도 출처 모를 binary 파일만 굴러다녀 실행하기 불안하기도 합니다. 그래서 직접 만들어 소스코드까지 공개합니다.

Introduction Picture two doctors updating the same patient record at the same time - one in São Paulo, the other in London. Both are offline. When connectivity returns, whose changes prevail? This is not a hypothetical. It is the everyday reality of distributed systems: multiple nodes, no shared clock, no guaranteed network. The conventional answer has long been locking - one node waits while an
Introduction Some code works. Some code lasts. The difference rarely comes down to typing speed, syntax mastery, or how many nights you're willing to push through. It comes down to how you think about a problem before you write a single line. Big-O notation is a mathematical framework that describes how an algorithm performs as its input grows. In plain terms, it answers one question:
If you use ChatGPT, Claude, Grok, Copilot, or Gemini daily, it feels like you're talking to a person. It remembers what you said three messages ago. It references the project details you shared yesterday. It feels like the model has a persistent brain that is learning about you. But it’s a lie. From an architectural standpoint, an LLM is the most "forgetful" piece of software you will ever use. Ev
Most symbolic systems rely on multiple primitives. Addition, multiplication, exponentials, logarithms — each plays a different role in structuring expressions. But what happens if you force everything through a single operator? This idea becomes concrete with the EML operator: eml(x, y) = exp(x) − ln(y) In theory, this operator can express all elementary functions. But theory doesn’t tell us what
