2026-04-27Optimization as the bridge to computational finance - Comp-fin rests on three pillars (stochastic calculus, numerical methods, optimization); convex opt + DP + stochastic control are the workhorses, not MILP2026-04-27Operations Research and MILP for software engineers - OR is declarative problem solving with a solver; MILP is one technique inside mathematical optimization, the rest is modeling2026-04-27macOS Input Method Kit (IMK) architecture and lifecycle - Out-of-process IM model, Mach IPC keystroke routing, Secure Input pain points2026-04-25Claude Code surfaces - CLI vs web vs desktop and resource usage - Four surfaces, three runtimes; desktop Electron costs ~2x RAM and runs hot, CLI + web is the leaner pattern2026-04-25How to win at office politics (BusinessCringe) - The invisible scoreboard runs on perception, not performance; can't opt out, three offensive tactics to defend against, three defensive plays to run2026-04-24age and 1password as complementary encryption tiers - Two-tier backup: 1P for availability, age for offline recovery; key-separation principle (key and ciphertext must have different failure modes)2026-04-22age, a modern file-encryption CLI - Small opinionated replacement for GPG-for-files; native SOPS backend, SSH-key identities, no keyring state2026-04-22Cloudflare Workers as a monitoring backend for self-hosted Linux - Agent + Worker + D1/KV free tier beats Kuma/Netdata/Prometheus for the 1-20 host solo operator2026-04-22HIDS-lite rule set for a single-operator Linux VPS - 15 rules over cheap shell signals catch 80% of script-kiddie-tier compromises; out-of-band engine required2026-04-21Leadership in the agentic era - When agents absorb execution capacity, taste + trust + context become the scarce leadership work; coordination time collapses2026-04-21Tao Te Ching + I Ching on timing and hidden preparation - The hidden dragon still trains: wu wei is preparation during a red light, not idleness2026-04-20GeckoTerminal API evaluation - Keyless H1/H4 OHLCV for DEX pools; 14/15 ADOPT; same data as $129/mo CoinGecko Pro2026-04-19Static outbound IP solutions for crypto trading bots, ten options compared - 10 options across 5 categories; every commercial static-IP service re-bundles "rent a VPS" with markup2026-04-19Why rotating ISP IPs break Binance API keys, and how to fix it with WireGuard - Cheap VPS + WireGuard beats every bundled static-IP product for exchange whitelisting2026-04-19deepagents vs OpenClaw vs Hermes: category positioning - Library vs runtime distinction; the three are not peers and stack rather than compete2026-04-19AI tooling stack synthesis April 2026 - Synthesis: 3 layers wired through one rubric; growth and adoption-readiness are inversely correlated2026-04-19OpenBB evaluation - Python-first financial SDK; 11/15 BOOKMARK; crypto value thin, TradFi inflection point2026-04-19OSS trading stack survey, April 2026 - 3-category synthesis; Freqtrade + VectorBT canonical for semi-pro crypto; ai-hedge-fund as first agentic pilot

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 |
Full reference: commands cheatsheet in the usage guide.
