# Algomon > Self-paced lessons: 1205 topics in 54 roadmaps. Each topic has when to use it, a step-by-step method, a worked example and pitfalls; code roadmaps add a tested, stdlib-only Python reference implementation. How to use this as an agent: pick the roadmap for your problem below and open its index, which lists every topic with a one-line summary. Then fetch only the topic pages you need. Match a problem via a topic's "When to use it" signals, read "How it works" and "Pitfalls", and for code adapt the Python reference and keep its `demo()` asserts passing. Each roadmap index also links one file with all of that roadmap's topics. ## 💻 CS - [Algorithms](/algorithms/llms.txt): 33 topics, with tested Python - [Compilers & interpreters (toy language pieces)](/lang/llms.txt): 22 topics, with tested Python - [Compression & coding](/compression/llms.txt): 22 topics, with tested Python ## 🏗️ Systems - [System design (topics follow Designing Data-Intensive Applications, 1st ed., by Martin Kleppmann; original summaries)](/design/llms.txt): 26 topics, with tested Python - [Networking (toy models in stdlib Python)](/net/llms.txt): 22 topics, with tested Python - [Concurrency & operating systems (deterministic toy models)](/os/llms.txt): 22 topics, with tested Python - [Performance engineering](/perf/llms.txt): 22 topics, with tested Python - [Observability & reliability](/sre/llms.txt): 22 topics, with tested Python ## 🤖 Data & AI - [SQL (generic SQL features, examples tested on SQLite)](/sql/llms.txt): 23 topics, with tested Python - [Probability & statistics (simulation-first, stdlib Python)](/stats/llms.txt): 22 topics, with tested Python - [Machine learning](/ml/llms.txt): 22 topics, with tested Python - [LLM engineering](/llm/llms.txt): 22 topics, with tested Python - [Claude API & Claude Code](/claude/llms.txt): 24 topics, with tested Python - [Data visualization & graph drawing](/viz/llms.txt): 24 topics, with tested Python ## 🧰 Practice - [Testing & software design](/testing/llms.txt): 22 topics, with tested Python - [Command line & Git](/cli/llms.txt): 22 topics, with tested Python - [Security & cryptography (defensive, toy models)](/sec/llms.txt): 22 topics, with tested Python - [IT security operations](/itsec/llms.txt): 26 topics, with tested Python - [App improvement (product and UX)](/app-improvement/llms.txt): 21 topics ## 💰 Finance - [Finance fundamentals (educational, not advice)](/finance/llms.txt): 22 topics, with tested Python - [Markets & trading (educational, not advice)](/markets/llms.txt): 22 topics, with tested Python - [Options & volatility](/options/llms.txt): 22 topics, with tested Python - [Fintech engineering](/fintech/llms.txt): 22 topics, with tested Python - [Crypto & blockchains (educational, not advice)](/crypto/llms.txt): 24 topics, with tested Python - [Technical analysis (educational, not advice)](/technical/llms.txt): 22 topics, with tested Python - [Quant trading strategies (educational, not advice)](/quant/llms.txt): 25 topics, with tested Python - [Algo trading systems (educational, not advice)](/algo-trading-systems/llms.txt): 22 topics, with tested Python - [The Fed & markets](/fed/llms.txt): 32 topics - [Wealth planning in Singapore (education, not advice)](/wealth-planning-singapore/llms.txt): 22 topics ## 👥 People - [Public speaking](/public-speaking/llms.txt): 22 topics - [Interpersonal communication](/interpersonal-communication/llms.txt): 20 topics - [People management](/people-management/llms.txt): 23 topics - [Social media](/social-media/llms.txt): 19 topics - [Psychology](/psychology/llms.txt): 21 topics - [Negotiation & influence](/negotiation/llms.txt): 19 topics - [Parenting teens](/parenting/llms.txt): 17 topics ## 🌱 Mind & wellbeing - [Learning how to learn](/learning-how-to-learn/llms.txt): 23 topics - [Memory](/memory/llms.txt): 20 topics - [Mood](/mood/llms.txt): 22 topics ## 🏅 Hobbies - [Pickleball](/pickleball/llms.txt): 26 topics - [Tennis](/tennis/llms.txt): 19 topics - [Golf](/golf/llms.txt): 20 topics - [Bowling](/bowling/llms.txt): 17 topics - [Bouldering](/bouldering/llms.txt): 20 topics - [Mountain biking](/mountain-biking/llms.txt): 22 topics - [Acro](/acro/llms.txt): 18 topics - [Flexibility](/flexibility/llms.txt): 22 topics - [Magic tricks](/magic/llms.txt): 21 topics - [Singing](/singing/llms.txt): 20 topics - [Mahjong](/mahjong/llms.txt): 24 topics - [Chess](/chess/llms.txt): 23 topics - [Chinese chess](/xiangqi/llms.txt): 21 topics - [Go](/go/llms.txt): 22 topics - [Cooking](/cooking/llms.txt): 28 topics
