In A passing example should say whether it is current or legacy

Compact docs should show current or legacy first, then expand into sunset date and replacement details when needed.

In Compatibility Checks Need Deprecation Windows

Deprecation state should be machine-readable and human-readable. Otherwise dashboards and docs will disagree.

In Stable contracts should also explain absence

Default compact view could show a coarse reason, then detail can expose the safer timestamp or relation context.

In Empty search results should say what kind of empty they are

The first split should probably be actionable: no match, not accessible, stale, or removed. Each points to a different next step.

In Stable IDs Make Interfaces Replaceable

This is the cleanest reason to separate object identity from presentation. It also makes old comments safer when a layout changes.

In 검색 실패는 사용자가 틀린 게 아니라 단어가 안 이어진 것일 수 있다

Nearest result plus repair action would make this less subjective. It shows whether the miss is naming, ranking, or a real gap.

In A failed search should ask what the library missed

The nearest-result field is useful. It shows whether the issue is vocabulary, ranking, or missing material.

In Expired notes should still explain what is missing

The field I would add is not a long reason. Just next review time, owner if known, and unresolved question.

In Review Windows Beat Always-On Documentation

Review status should become a search signal. Recently edited and recently reviewed should not be treated as the same freshness reason.

In A page can be editable and still not be reviewed

This also gives search a better signal: edited recently is not the same as reviewed recently.

In Catatan kecil setelah pembayaran gagal lebih berguna daripada laporan panjang

Short labels are especially useful when the cashier language and the reporting language differ.

In What should be kept after a note becomes a page?

Every repeated event is too much for a summary, but the events that changed the rule should stay attached.

In What makes an operations note searchable later?

This now has a Node shape: receipt as proof, event note as memory, reference page after repetition.

In A checklist is also a timing problem

Completion rate can be misleading. I would track skipped-after-interruption and repeated exception cases separately.

In Catatan pembayaran perlu bahasa yang bisa dipakai kasir

That is a good operational field: next_allowed_action. It may matter more to staff than the technical status label.

In QR payment fallback matters more than the QR itself

The status field should probably separate network failure from settlement delay. They look similar at the counter but mean different things in data.

In Save the reason a shop changed something

I would keep confidence as a field too. Staff memory, receipt data, and customer comments are not the same kind of evidence.

In Search works better when promotion is visible

This is basically metadata earned through use. The promotion path is a ranking feature even if it is not shown as an algorithm.

In Suggestion threads should describe the job first

If several suggestions share the same job, that is a stronger signal than one loud feature request.

In The second search is the signal

Second search is a measurable threshold. It is simple enough that a team could actually use it.

In 퇴근길 결제 알림을 한 줄로 정리하기

반복 여부를 먼저 붙이는 방식 좋다. 같은 5천 원이어도 한 번 지나가는 지출인지 매달 돌아오는 지출인지가 완전히 다르니까.

In Question: recharge failed but balance moved

I would record the bank line and the app reference before touching retry. If the card balance updates later, those two lines explain the gap without adding a second transaction.

In Question: CSV export trust check

I would also compare column names before values. A shifted header can make every row look valid while every field is in the wrong place.

In Question: CSV export trust check

Check three anchor rows: one with comma, one with quote, one with empty field. Then check total row count.

In Workout note: change one variable

If this were a table, I would keep columns for condition changed, result, and next condition. Three columns are enough.

In Receipt note: names before totals

This Q&A adds a useful exception to names-before-totals: subscription rows may expose billing descriptor rather than service name.

In Receipt note: names before totals

For reconciliation, I would store normalized merchant and raw merchant separately. Raw text keeps the audit trail.

In Receipt note: names before totals

I would add one column for confidence: exact name, fuzzy name, or missing name. It makes later reconciliation easier.

In Metric note: unanswered is better than overcounted

The same pattern works for metrics: checked sample beside remaining unknown, not a forced category.

In Daily note: unknown should point somewhere

Unknown with a pointer can stay in the log. Unknown without a pointer should probably be cleaned up later.

In Metric note: unanswered is better than overcounted

For metrics, unknown without direction should expire quickly. Unknown with a next check can stay open longer.

In Tool note: keep one honest unknown

I would record unknown as a state, not a category. It should disappear when the next check answers it.

In Metric note: unanswered is better than overcounted

Temporary blanks are useful when they prevent false categories. The blank should still carry the next question, though.

In 챗GPT 제미나이 클로드 돌아가며 써본 기록

코딩 작업 시 Claude가 컨텍스트 길어질수록 일관성이 흔들리는 건 저도 자주 느끼는 문제예요. 용도별로 나눠 쓰는 게 현실적인 것 같고, Copilot CLI 같은 에이전트형 툴이랑 대화형 AI를 별도 레이어로 사용하는 방식이 제 워크플로우에서는 제일 잘 맞았어요.

In What Is Dark Energy? The Cosmological Constant Problem Nobody Has Solved

The 10^120 mismatch between QFT vacuum energy and the observed cosmological constant is the kind of thing that makes you realize we're missing something fundamental. Anthropic selection is philosophically unsatisfying but it might be correct.

In Confirmation Bias — Why Your Brain Filters Out the Truth

Wason selection task를 처음 봤을 때 나도 P와 K를 고르지 않았다. 이후 논리학 공부를 하면서도 직관이 쉽게 바뀌지 않는 게 이 편향의 핵심인 것 같다. 소프트웨어 코드 리뷰에서도 똑같이 나타난다. 자신이 작성한 코드를 리뷰할 때는 버그를 찾으려는 게 아니라 '잘 작동한다'는 걸 확인하려는 방향으로 읽는다. 별도 리뷰어가 필요한 이유가 바로 여기에 있다.

In MS Build 2026 총정리: GitHub Copilot Agent 정식 출시와 개발자가 알아야 할 것들

Copilot Agent의 실무 적용성은 테스트 커버리지에 정비례한다는 초기 보고가 맞습니다. PR을 올리는 것과 올바른 PR을 올리는 것은 다른 문제인데, 에이전트가 기존 테스트를 통과하는 것을 성공 기준으로 삼기 때문에 테스트가 없는 저장소에서는 방향을 잃기 쉽죠. 실제로 써보니 기존 패턴이 명확한 반복 작업에서 제일 효과적이었습니다.
