2026-05-17Why Quantum Computing Talks About Decision Problems - Decision problems are the assembly language of complexity theory; YES/NO falls out of the Born rule; apples-to-apples quantum-vs-classical comparison requires shared output shape2026-05-17History and motivation of major quantum algorithms - Shor / Grover / HHL / VQE-QAOA as a story of outsiders importing intuition from other fields; speedup requires structure; HHL dequantization shows caveats are the whole story2026-05-17State preparation is half the quantum algorithm - Every algorithm has three stages; preparation is where exponential speedup claims die; the headlines focus on operations, the engineering reality lives in encoding2026-05-17Quantum superposition state and QFT for beginners - Quantum speedup is not "try all options in parallel"; it's interference canceling wrong answers; QFT is the engine inside Shor that extracts hidden periods2026-05-17Complexity classes P NP BQP QMA explained - Classical P/NP hierarchy extended with BQP and QMA; Shor lands factoring in BQP, P vs NP and BQP ⊆ NP both open; RSA's safety rests on empirical P ≠ NP2026-05-17What polynomial time actually means - Polynomial = highest exponent is a fixed constant; n^10 is polynomial, 2^n is not; the threshold complexity theory draws between tractable and intractable2026-05-17Vietnamese terminology for quantum computing - Working glossary: chồng chập for superposition, vướng víu vs rối for entanglement, when to keep English (algorithm names, acronyms)2026-05-17Monomial polynomial term Vietnamese terminology breakdown -thứcinđơn thứcis NOTcông thức; etymology of-nomialfrom Latinnomen; Ising Hamiltonians as degree-2 polynomials in Pauli operators2026-05-15iCloud Advanced Data Protection: coverage, exclusions, and recovery model - ADP extends E2EE to almost everything in iCloud, but Mail/Contacts/Calendar stay Apple-readable forever; three-axis decision (coverage, recovery, operations) instead of one binary switch2026-05-09Hermes Agent v0.13.0 release evaluation: top features ranked for 3-tier ecosystem - Selective adoption verdict; CLONE Kanban + cron no_agent, ADOPT /goal + session resume, STUDY security wave; skip i18n / Google Chat / video tool hype

Claude AI skill (refined)┘
- Ingest: new knowledge arrives from web clips, coding sessions, or research conversations
- Compile: the LLM checks for overlaps, flags contradictions, updates cross-references and synthesis pages
- Query: ask questions against the compiled wiki; good answers get filed back as new notes
- Lint: periodic health checks for orphans, broken links, stale claims
The human thinks and curates. The LLM handles the bookkeeping.
Type these to Claude in this repo (exact wording doesn't matter, intent does):
| Command | What it does |
|---|---|
process inbox |
Refine raw _inbox/ captures into the right folder with links |
capture this as a note: ... |
Save a learning moment from the current chat |
compile recent commits / re-ingest |
Run compilation on notes pushed directly to GitHub (backlinks, index, README, log) |
answer from the wiki: ... |
Synthesize across notes, cite with [[wikilinks]] |
file that answer as a wiki page |
Commit a synthesis from chat as a new note |
reorganize the wiki |
Clean up orphans, folders, backlinks |
lint the wiki |
Health check: orphans, broken links, raw stragglers |
