#best-practices

• Sat, Nov 8, 2025. Notes from How to build a cult, Lulu Cheng, The Knowledge Project #best-practices #beliefs
  • Conviction is infectious.
  • Communicate at the INTERSECTION of interests. Learn theirs
  • Begin with "why your story matters to them" (first sentence). That beats "how you tell it" > "where you tell it".
  • The easiest way to align with an audience is to find your community.
  • Humor, curiosity, awe, any strong emotion is a hook.
  • Culture has momentum. Best way to break it is to show an alternative that works. People will copy that
  • REPEAT messages over and over with complete CONVICTION to convince people who TRUST you. That works, but you need all three.
  • Trust builds from likeability, repeated exposure, common beliefs.
  • An excellent way to defend against online criticism (when it matters) is to just SHOW UP and THANK them for feedback.
  • Serious reputational damage must either be fixed immediately - or you live with it forever.
  • Between a story and statistics, the story will always wins. Never fight a story with a statistic. Dig into your statistics and uncover BETTER stories.
  • ⭐ Prebuttals are a great idea. Start with all possible criticisms yourself and diffuse them. The other person has nothing left to say
  • Sparring keeps you sharp. Spar with LLMs.
  • To defend, show how the attack targets other people, increasing the surface area. Show how the SPECIFIC attack targets a larger group. Create a SPECIFIC cause worth fighting for.
  • Each role has specific objective to optimise for. The leader's role is to balance across these.
  • Cheerleader effect. People look beautiful next to a cheerleader. Associations taint.
  • Each person has dozens of aspects to their persona. We cannot remember all of them. Each person can make a choice on who they project themselves to be in any group. Shaping their persona.

• Sat, Nov 8, 2025. Notes from How I use every Claude Code feature #ai-coding #best-practices #code-agents #github #markdown #prompt-engineering #write
  • Use AGENTS.md as guardrails, not a manual. Document what it gets wrong.
  • Use self-documenting tools/APIs rather than documenting.
  • Docs: Explain why and when to read each doc.
  • Never say "Never." Explain when to which which alternative.
  • Prefer CLIs for stateless tools, MCPs for stateful, authenticated, or complex (e.g. Playwright).

• Sat, Nov 8, 2025. When using MCPs or tools with private data, "color untrusted content in red, exfiltration actions in blue, and never mix colors." Good advice. #best-practices #code-agents #darker-color

• Wed, Nov 5, 2025. Based on responses to Simon Willison's question, ChatGPT #automation #best-practices #future #gpu #optimization #prompt-engineering
  • Fine-tuning helps when:
    • Lower latency, e.g. for type-ahead, at lower cost (37 mentions)
    • Structured extraction, parsing and classifiers, e.g. postal address, detecting secrets (18 mentions)
    • Custom vision models, e.g. check containers (12 mentions)
    • Domain-specific code and stacks (niche languages, stack-specific generation, text→SQL) (11 mentions)
    • ... and a long tail.
  • Fine tuning does not help:
    • When A base model plus prompting or RAG does as well or better (15 mentions)
    • When you risk being leapfrogged by a new release (4 mentions)
    • When cost and data do not justify the ROI (3 mentions)

• Sat, Nov 1, 2025. Notes from Vanya Seth's keynote at OSAI HYD #ai-coding #automation #best-practices #code-agents #prompt-engineering
  • Superpowers of Gen AI to keep in mind when exploring AI coding agent use cases:
    • Translating. Requirements to code, code to code, language to queries, standard to standard.
    • Finding info just-in-time (in context). How does this work? What's this error? What tools are permitted in my org? Who knows what? E.g. Atlassian Rovo queries across JIRA, Confluence, etc.
    • Brainstorming and ideation. Product ideation. Requirements. Testing gaps. Architecture review. Exploratory / scenario testing.
    • Summarizing and clustering. Change logs, incident management, research data, docs summary.
  • Challenges in using AI coding agents:
    1. Adoption imbalance. Only certain roles are amplified by AI. Coding, QA, more than planning, maintenance, AI ops, etc. What's the impact of this?
       • ⭐ Goldratt's ToC implies that backlogs need to fill faster. Downstream becomes a bottleneck. Technical debt piles up.
       • ACTION: Use AI across entire value chain, from research to maintenance.
    2. Locality. enhances roles (nodes), not relationships (links). They optimize local work, not global flow. Workflow tools are missing.
       • Coordination overhead. Context Fragmentation. Translation problems.
       • ⭐ Expand productive roles to cover neighboring tasks. Productive developers shift left and build backlogs; shift right to reduce code review, maintenance tasks.
         • E.g. Move maintenance/production activities into development. Security, performance, monitoring, observability, cost, infrastructure.
         • We spend time on IDE, CI/CD, Jira, Confluence, Prod observability tools.
         • A typical Agent Development Platform (ADP) covers evals, guardrails, workflow builder, agent builder, observability, prompt management, AI gateway (LiteLLM), MCP servers, model fine-tuning, model serving, model repository, vector stores
         • We need ADP Agents covering delivery risk, continuous security, prod issues RCA, observability, performance, accessibility, product research, infra optiimzation, test data generation, anomaly detection, release management
         • ACTION: Share ADP photo with Patrick.
    • ACTION: ⭐ Centralize skills ("knowledge packs") and MCPs and observe which gets used most. Allow people to use more.
    3. Lethal Trifecta. There's growing demand for higher productivity with AI code assistants. But the lethal trifecta makes them an attack vector. It has access to sensitive information, exfiltrate data, and read and follow unsafe instructions.
       • Can lead to supply chain poisoning attacks.
       • Regulated industries cannot adopt.
    4. Technical debt growth. More productivity leads to poor code quality which will slow down future work.
       • See Software Engineering Excellence 2025
       • AI induced complacency.
       • Sunk-cost fallacy on AI-generated code hurts.
       • ACTION: Evaluate code quality continuously to reduce technical debt. Double-down on good engineering practices.
    5. Compliance.
       • Model residency. Self-hosting is required.
       • Data observability gaps. Data privacy, audit trails, etc. are concerns.
       • Token economics. $20/day happens in Thoughtworks. Token cost is subsidized.
       • Rogue AI usage. Use of dis-allowed tools; shadow IT.
       • ROI justification. Hard to quantify productivity gains.
    6. Adoption.
       • AI Literacy. Tap into organizational knowledge
       • Champions & communities of practice to support cross-pollination.
       • Use-case driven adoption. Teams identify based on AI superpowers.
       • AI playbook. Share what worked, what didn't work.

• Mon, Oct 27, 2025. Things that I currently follow and don't follow from Peter Steinberger's excellent Just Talk To It: #best-practices #code-agents #github #prompt-engineering
  • Prefer Codex > Claude Code.
  • Ask for options before executing
  • Generate & review specs collaboratively
  • You don't need git worktrees
  • Prefer subscriptions over API to reduce cost
  • Store docs with code
  • Give examples
  • Use voice input
  • Use Codex Web as a mobile inbox for ideas
  • Prefer CLI over agentic platforms
  • Prefer CLI tools over MCP
  • Avoid ALL-CAPS for Codex. It follows instructions well
  • Avoid subagents, RAG, etc.
  • Iterate UI live. Watch changes
  • Use 3-8 agents in parallel on a single repo.
  • Make small, atomic commit checkpoints. Commit only what the agent touches
  • Add ast-grep as a pre-commit hook to block rule violations.
  • Keep custom prompts minimal (commit, automerge, massageprs, review, ...). Just "commit" reduces context
  • Cancel long tasks and ask what's happening
  • Prefer Medium over High reasoning. It decides level of thinking
  • Share screenshots
  • Use tmux to run CLIs persistently
  • Schedule refactor time (20%). Use jscpd, knip, oxlint, ...
  • Don't reset context. Cold start wastes time + tokens
  • Write tests in the same context. Yields better tests, reveals bugs.
  • Prototype in a separate folder / PR
  • Queue continue messages** before stepping away
  • Ask it to "Preserve intent and add comments at tricky spots". Future you needs the WHY
  • On hard problems, add “take your time”, “be comprehensive”, “read all related code”, “form hypotheses”, etc.
  • Maintain an evolving AGENTS.md with product notes, naming, API patterns, test policy, ast-grep rules, etc. Delete stale guidelines

• Sat, Oct 25, 2025. Before founding a place to do good, work in a place that does good and learn. Ben Werdmuller #best-practices #future #web-dev

• Mon, Oct 13, 2025. ⭐ Always include a thoughtful gallery of examples with tools / libraries. This does more than showing what a tool can do. #best-practices #features #image-generation #markdown
  • It's use-case / domain transfer: showing what it's useful for in real life - opening ideas, suggesting workflows.
  • It's style transfer: showing how to use it.

• Mon, Oct 13, 2025. ⭐ Here's what expert AI coders increasingly focus on. Thomas Dohmke #ai-coding #automation #best-practices #code-agents #dev #future #optimization #prompt-engineering
  • Delegation: context engineering agents for success; parallelizing.
  • Verification: efficiently reviewing and testing code/output; setting stop-points.
  • Expanding scope: instead of time saved as the metric.
  • Education: teaching AI-based coding, debugging, reviewing/testing.
  • Product management: combining requirements + UI design + architecture + engineering + deployment.
  • Cross-discipline: blending code with design, governance, finance, marketing, ... ("computational creators").

• Mon, Oct 13, 2025. IDEA Teach AI like driving. Scan ahead (context engineering). Safe gap (budget discipline). Speed control (safe answer first). Hazard anticipation (known failure modes). Seat-belt discipline (citations, counter-examples). #ai-coding #automation #best-practices #code-agents #future #prompt-engineering #prediction

    • Publish a responsible AI playbook (what's safe to try)
    • Audit AI practices quarterly

• Thu, Oct 9, 2025. Core concepts of directing shorts #best-practices #optimization #prompt-engineering
  • Open with a specific curiosity gap in the first 1-2 seconds. Give viewers a concrete unanswered question or visually odd setup ("Why is the coffee floating?") so the brain needs to resolve it. This is supported by short-video best-practice (hook early) and the "information-gap" theory of curiosity. Prompt tip: Start with one line that states the unresolved situation, then specify the exact first frame
  • Use a 3-beat micro-arc (setup > build > payoff) sized for 6-20s. Don't cram a film; deliver one story beat every few seconds. The YouTube/Think with Google ABCD work (Attract, Brand, Connect, Direct) shows simple, purposeful structures outperform meandering ones-especially at bumper-ad lengths. Prompt tip: Add a tiny beat sheet with timestamps: "0-2s setup, 2-6s escalation, 6-8s payoff."
  • Design the last moment first (Peak-End). Viewers remember the high point and the ending more than the duration; plan a twist, reveal, or "aha" and cut right after it. This is the Peak-End rule from psychology; in practice you'll see it as spikes near the end in retention graphs. Prompt tip: Write the final shot first; ensure the last frame resolves the opening question
  • Pace with micro-beats and pattern interrupts. Change something every 1-2s (camera angle, scale, color, motion, prop) to reset attention without chaos. Platform guides stress tight pacing and clear structure for mobile attention windows. Prompt tip: List planned interrupts: "1. whip-pan, 2. hard cut to macro, 3. foreground object crosses lens."
  • Max processing fluency: big, high-contrast, simple frames. The brain rewards "easy to process" visuals (clear figure/ground, symmetry, repetition)-they feel better and read faster on a phone. Keep one subject per shot; use bold contrast; minimal text. Prompt tip: Specify composition ("tight medium on subject, high contrast rim-light, uncluttered background, single color accent")
  • Constrain on purpose: one change, one location, one idea. Constraints raise creativity and clarity. Micro-budget directing advice and 6-second ad research converge: pick one surprising constraint and lean into it. Prompt tip: State the constraint up top ("single hallway; only practical light; one prop changes form")
  • Exploit visual salience and motion immediately. High-salience elements (faces, movement, contrast) pull gaze fast-vital on scroll feeds. Start with motion crossing the frame or a face entering; cut on action. Prompt tip: "Frame opens mid-action; subject crosses left>right; parallax background; quick dolly-in."
  • Make sound part of the story, not wallpaper. Sync cuts to beats, use distinct diegetic sounds (whoosh, click, crunch) as transitions, and specify audio intent in the prompt. Veo's guide explicitly recommends fusing visuals with sound design. Prompt tip: Include an "Audio" block ("quiet street > sudden clack > riser swell; cut on snare")
  • Direct the model like a DP: shot grammar in the prompt. With Sora/Veo you get better control when you name the lens, camera move, lighting, and blocking-and outline complex action step-by-step. Veo shows gains from highly detailed, play-by-play prompts; Sora exposes a storyboard interface for frame-accurate control. Prompt tip: "35mm lens, handheld, subtle breathing; golden-hour backlight; beat-by-beat action list."
  • Iterate on retention, not vibes. Use YouTube's "Key moments for audience retention" to find spikes/dips; move top moments earlier, trim dips, and test a few alt cuts. Shorts auto-loop and rewatch spikes often correlate with a strong twist/payoff. Prompt tip: After v1, generate two alternates: (A) earlier reveal, (B) tighter mid-beat; compare retention

• Mon, Oct 6, 2025. Many people who shifted away from conflict aversion did so by systematizing it. ChatGPT #best-practices

• Sun, Aug 31, 2025. From My experience creating software with LLM coding agents - Part 2 (Tips) #ai-coding #best-practices #code-agents #dev #github #prompt-engineering
  • Use standards. Or, write your standards in README.md and tell AGENTS.md / CLAUDE.md to read it.
    • Use a standard file structure. Or in README.md, list what each file is for. Helps agents pick the right file for context.
    • Use a standard build/lint/test setup (e.g. package.json scripts). Or
  • Localize context, i.e. add context in files that use them. E.g. add comments in test files on how to execute them.
  • Keep files modular so agents can read less code and conserver context.
  • Write a developer's guide.
    • Use with /init in Claude Code / Codex / ... or have an LLM generate a developer guide.
    • Edit manually. Agents don't write great specs.
    • Document the design.
    • Write DETAILED specs to reduce deviations.
  • Share goal while specifying tasks. Helps agents fix related stuff.
  • Use deep reasoning mode, e.g. "think harder" or "ultrathink" in Claude Code, or -c model_reasoning_effort=high in Codex.
  • ⭐ Run parallel agents in different windows and share agent feedback with each other. E.g.
    • Server/API coding in one window. Client coding in another.
    • Plan/ask in one window. Execute in another.
  • Add debug logs to help agents spot errors.
    • Start/stop of long/complex operations, state changes, external interfaces.
    • Include full objects in logs. Prioritize diffs. Trim long contents.
    • ⭐ Give access to debugger, e.g. Chrome remote debugging at localhost:9222
  • Agents write poor tests. So:
    • Manually add important ones.
    • ⭐ When you find a bug, ask the agent why the tests missed it and have it add.
    • Review and remove useless ones.
  • Ensure agent passes test cases. Tell them not to disable / skip failed tests.
  • Have agents create a new branch per feature and auto-commit. Merge when successful.
  • Feel free to provide a TODO list or update it on the fly.
  • Interrupt with Esc if the agent's thinking is off-track.
  • When agents struggle, write tools to help them, e.g. JSON splicing, Excel edits, etc.
  • Agents bloat code and features. Explicitly refactor and trim.

• Sat, Aug 30, 2025. ⭐ Habit tooling can expand habit-building capacity. I already use tools to support my habits. Habit stacking "sticks" new habits to old ones. By sticking new habits into existing tools, I can automate this. (For example, I extended my meeting record fish script with an echo reminding me to write the meeting goal, my role, practice kind candor, and measure effectiveness.) #automation #best-practices #future #prompt-engineering

• Tue, Aug 26, 2025. When seeking advice, people sometimes think aloud, become repetitive, and introduce detail before clarifying intent. Kind candor helps. You can: #best-practices #optimization #prompt-engineering
  • State time boundaries. "We have 20 min. If we spend 5 min on your question, we'll have 15 for solutions."
  • Clarify intent upfront. "Before we dive in: What can I help with?"
  • Interrupt, summarize, clarify early. "Cooperative interruptions" are seen as supportive. E.g. "I get this: six accelerators, two done. Great! What can I help with? To accelerate?"

• Mon, Aug 25, 2025. With AI coding, task breakdown, context right-sizing, and automated testing are key levers. #ai-coding #automation #best-practices #code-agents #future #optimization #prompt-engineering

• Fri, Aug 22, 2025. ⭐ Creating systems that rapidly improve from feedback is the key to success. Rapidity, quality of improvement, quantity of feedback are all enablers. #best-practices #future #optimization #prompt-engineering

• Wed, Aug 20, 2025. Given the early, experimental days of AI, the better KPIs might be more about experimentation (e.g. number of prototypes) than operational (e.g. cost reduction). Krishnakumar Menon #best-practices #future #optimization #prompt-engineering

• Wed, Aug 20, 2025. The ROI of prompting carefully and using meta-prompts is high. Prompt clarity reduces iterations & dead-ends. The initial time spent (10-15 min) pays off with just a single reduced iteration (time to generate + review). Tanika Gupta #best-practices #optimization #prompt-engineering

• Sat, Aug 16, 2025. ⭐ From Daniel Kahneman, The Knowledge Project Podcast. #best-practices
  • Key lesson. Have lower expectations. Behavior change is hard.
  • Happiness is pleasure in the moment. Satisfaction is the meaningful story of our life. When reflecting, the thinking brain wants satisfaction. When feeling, the feeling brain feels happiness. The 2 brains optimize for different things. The thinking brain packs the calendar with satisfying tasks that the feeling brain hates doing.
  • Happiness & pleasure are both are good for us. We don't know which matters more.
  • Behavior change is harder than most people think. Usually, it's better not to expect success. Changing others, or ourselves.
    • Instead, understand the cause of that behavior. Behaviour is an equilibrium of forces.
    • Weakening forces preventing right behaviour is easier than strengthening forward forces. It lowers tension. That's inversion!
    • Behaviours are more about situations than personality. We assume otherwise - that's an attribution error.
    • Environment shapes thinking but it's not obvious how, e.g. some people work better in noisy cafes. Some colors are more calming.
  • Leadership & delegation
    • Motivation is complex. People can do bad things for good reasons and vice versa.
    • So, delegate decisions to unemotional agents. But agents misjudge perceived value of gain or loss!
    • People prefer over-confident intuitive leaders over slow, deliberate leaders.
    • Protect dissenters and dissent. It's painful and costly, and needs nurturing.
  • Negotiation is about understanding, not convincing.
  • "Feelings get in the way of clear thinking."
    • Example: I vibe-coded the last 2 questions of TDS GA7 on Claude Code. It didn't run. I delayed fixing it for 5 days, afraid it would a major effort. It ended up a 2 min fix. It could have been major, but checking would have helped. Fear prevented that.
    • Intuition, emotion, beliefs hamper clear thinking. Beliefs are often formed based on people we admire or identify, not reason.
  • What enables clear thinking (all are hard):
    • Pragmatism. Don't threaten your identity, the leader, etc. Else none of this works.
    • Rules, systems and processes. Willpower is illusion. Alignment is an illusion. "Whereever there is judgement, there is noise, and more than what people think."
    • Standards. Shared, consistent scales of evaluation. Super-forecasters use probability scales.
    • Deliberation. Slow decision making.
    • Decomposition. Break down the problem, analyze it, THEN form an intuition. Be disciplined in delaying intuition or forming an opinion.
    • Pre-mortems. "Write the history of the disaster this decision led to."
    • Decision journals with post-mortems. Pros, cons and alternatives from failed decisions, e.g. Ray Dalio's principles. Change of mind.
    • Independent data. Use data. Keep evidence gatherers independent of decision makers.
    • Preparation. Have decision makers write down decisions before discussing. Increases diversity.

• Sat, Aug 16, 2025. From the GPT 5 coding cheatsheet: #ai-coding #best-practices #code-agents #optimization #prompt-engineering
  1. Be precise and avoid conflicting information. Use a prompt optimizer to check for inconsistencies.
  2. Use the right reasoning effort. Prefer medium or low reasoning to avoid overthinking simple problems.
  3. Use XML-like syntax to help structure instructions
  4. Avoid overly firm language, e.g. "You MUST be THOROUGH" vs "Thoroughly".
  5. Give room for planning and self-reflection. Explain what to do in steps, asking it to think deeply
  6. Control the eagerness of your coding agent, e.g. do not ask for confirmation, parallelize tool calls, use more tools, etc.

  • Automated testing
  • Standards
  • Capabilities of platforms
  • Modularity (and DRY vs WET)

• Mon, Aug 11, 2025. Discussion at PyConSG Edu Summit 2025. Padlet #ai-coding #best-practices #code-agents #prompt-engineering
  • Discussion validation
  • Interesting ways students use AI
    • Use AI to refactor/debug whole codebases
    • Get AI to create questions for practice
    • ChatGPT Study mode
    • Students like to upload photos. We can teach them to upload these to ChatGPT and ask questions.
  • What teaching practices / assessment design can help students think for themselves before turning to AI? ChatGPT
    • Interactive orals / micro-vivas (short, process-focused). Strong alignment with “interactive oral assessment” research and guidance in the AI era: improves authenticity, reduces outsourcing/contract cheating, and checks understanding. Make them low-stakes but frequent. How: 5–8 min viva tied to a task; students must explain choices, failures, and next steps.
    • Authentic / project-based assessments students can self-validate (observable outputs). Project-based and “authentic” assessment meta-reviews show consistent positive effects (achievement, thinking skills, motivation), especially in STEM and small teams. Design tasks with local data/constraints so generic LLM answers are only a baseline. How: “Default AI answer” gets a pass; “A-grade” requires empirical validation, custom data, or optimisation trade-offs with metrics.
    • Pair programming + peer critique on whiteboards/pseudocode. Evidence (meta-analyses & CS-ed studies) supports pair programming for learning and retention; code tracing/peer instruction deepen understanding before coding. How: Rotate driver/navigator; force commit-message style rationales; 10-minute “whiteboard dry-run” before touching IDE.
    • Process-over-product with structured reflection. Metacognitive/reflective interventions show medium-to-large effects on achievement; they also build habits that resist blind acceptance of AI outputs. Keep reflections short but structured. How: “What I asked AI; what it missed; how I verified; what I’d change next time.”
    • “No-AI under secure conditions” mixed with AI-permitted coursework. Matches national/institutional guidance for GenAI-aware assessment design. Use secure, time-boxed checks for fundamentals; allow AI elsewhere with audit trails.
    • Primary research (interviews/user studies) before design/coding. Fits the “authentic assessment” literature and reduces LLM substitution. Grade on research protocol + synthesis rigor, not word count.
    • Explicit problem-solving frames (initial/current/goal state). Classic problem-solving scaffolds; improves formulation before querying AI. Pair with short “assumption logs.” (General pedagogy supported; CT depends on domain knowledge -- see caveat below.)
    • Caveat (important): Critical thinking depends on domain knowledge. Don’t expect generic CT drills to transfer without content mastery. Plan tasks so students must recall/apply specific knowledge before or alongside AI.
  • How can we train students to use AI critically instead of accepting the output blindly? ChatGPT
    • Teach “lateral reading” and SIFT for source checking. Stanford’s Civic Online Reasoning work and Caulfield’s SIFT method offer actionable heuristics for verifying claims, URLs, and citations that LLMs surface. Build these into rubrics.
    • Run “AI auditing” labs (hallucination hunts). Students collect/label model mistakes, missing assumptions, and fabricated citations -- an approach aligned with UNESCO’s call for AI literacy and validation.
    • Use online judges with hidden tests + adversarial cases. Autograding literature supports hidden tests for robust generalization; it trains students to verify and not overfit to visible specs -- or to AI’s surface patterns.
    • “Sandwich” workflow: spec → implement 1–2 reps → let AI complete → verify rigorously. Mirrors human-in-the-loop patterns in industry; use checklists for unit/property tests and invariants before accepting AI output.
    • Live-coding with an AI assistant on display (to show failure modes). Demonstrates nondeterminism/limitations in real time; supports critical habits. Pair with a post-mortem template.
    • Prompt red-teaming/jailbreak exercises (safe scope). Students learn that guardrails can be bypassed and why verification matters. Keep it ethical and bounded.
    • Build a knowledge base first. Reinforce that CT sits on content knowledge; teach students to explain why an AI answer is plausible or not, citing domain facts.

• Mon, Aug 11, 2025. Notes from "Scaffolding the Problem-Solving Process for Introductory Computing Students" by Ashish Dandekar, NUS, at PyConSG Edu Summit 2025 #best-practices #optimization
  • Built an intelligent tutoring system
  • Encourage students to create their own pattern banks / cheat sheets. "Find 2 more problems that can be solved in the same way."
  • Focusing on the problem-solving process shrinks the gap. Students above the 50th percentile of pre-assessment did not improve much. The lowest percentile improved the most.
  • "At NUS, I know that even if I give 0.5% weightage for students attending tutorials, everyone will attend it for those 'free marks'."

• Mon, Aug 11, 2025. John Kotter's organizational change model is the accepted practice for top-down change, while ADKAR is for bottom up.

    • Time is a non-renewable asset.
    • Lifestyle design matters as much as net worth.
    • Future-proof against regret. The present matters, too.
    • Home ownership ties up location choice, capital and has hidden costs.
    • Market timing & geographic arbitrage has an outsized effect.
  • Software
    • Align abstraction to domain. Avoid premature abstraction (Don't Repeat Yourself vs Write Everything Twice) and over-abstraction.
    • Temporary fixes tend to stick. Stop-gap regexes last for years.
    • Consistency is a quality multiplier. Small inconsistencies cause disproportionate harm.
    • git bisect is a regression-finding superpower.
    • It's OK to write tests covering key parts of legacy codebases - 100% coverage isn't critical.
    • Document architectural decisions: why this approach. See Diátaxis.
    • Flow metrics predict delivery better than (arbitrary) estimates.
    • Building features without linking to delivery spesd wastes resources.
  • Life habits & learning
    • You have the right to say "no".
    • Small, consistent actions beat dramatic changes. Persistence beats skill.
    • You're allowed to change your mind.
    • Over-cleverness backfires. Witty code & communication lead to confusion.
    • Context is king. Without background, everything is mis-interpretable.
    • Fun leads to excellence. Excellence leads to fun.
  • The meta-lesson here is how I discovered these:
    • Run topicmodel to identify topics
    • Feed the output CSV to ChatGPT and ask it to share lessons topic-by-by-topic #

• Tue, Aug 5, 2025. ⭐ Slow, effortful practice (spaced recall, interleaving topics, self-testing) builds lasting knowledge but looks inefficient and doesn't help with exams. # #best-practices #future #learning #lesson #beliefs

• Mon, Aug 4, 2025. ⭐ In "kind" environments (stable rules, rapid and accurate feedback), specialize. In "wicked" environments (rules shift, feedback is noisy/late), generalize. ChatGPT #best-practices #chatgpt #code-agents #future #github #markdown #optimization #prompt-engineering

• Tue, Jul 29, 2025. From a post-mortem of 8 tasks Codex completed for me, here's what I need to improve when using LLMs to code. #best-practices #github #llm-ops #markdown #ai-coding
  • Provide a stable, complete spec.
    • Late UI tweaks, new API params, renamed fields, extra packaging rules, “Rename per‑image download”, “standardise baseUrl vs baseURL”, “add GA‑4 exam module”. → churn & rewrites.
    • Ask the user for a final UI/API/mock‑up + edge‑case examples before the first commit.
    • Lock naming conventions, UI layout and feature checklist early; track future changes explicitly
  • Include concrete examples.
    • Lack of sample images, Markdown snippets, question formats caused guesswork.
    • Supply mini‑fixtures: sample prompts, expected outputs, env‑var names, commit‑message template
  • Environment should be reproducible.
    • E.g. vitest not installed, .dev.vars absent, sub‑modules not cloned, network blocks.
    • Ship a one‑step bootstrap script / README with npm install, env‑var templates, and submodule notes
  • Automate tests.
    • First answer compiles but fails prettier/ruff/unit tests; later iterations fix style or red lines.
    • Codex should auto‑run lint && test (plus static‑analysis / self‑critique) before every response
  • Auto-run post-mortems.
    • Codex recommending its own static checks shows value.
    • Automate that as a pre‑commit step.

• Sun, Jul 27, 2025. Common themes in LLM chatbot system prompts (that are useful in other scenarios) are below. ChatGPT 🅐 = Anthropic, etc. #best-practices #code-agents #prompt-engineering

  19. Avoid flattery / filler / moralizing language (🅐🅼). "Claude never starts its response by saying a question… was good, great…"
  20. Political neutrality / multi‑viewpoint sourcing (🅐🆇). "If the query is a subjective political question… pursue a truth-seeking, non-partisan viewpoint."
  21. Location-aware behavior instructions (🅐🅞). "User location: NL. For location-dependent queries, use this info naturally…"
  22. Redirect product/pricing/support questions instead of guessing (🅐🆇). "... redirect them to https://x.ai/grok""

• Mon, Jun 30, 2025. ⭐ When bringing in humans-in-the-loop, applications must make it easier to review and to edit the work. #automation #best-practices #document-conversion #future #optimization #prompt-engineering #write

• Wed, Jun 25, 2025. A useful way to have reasoning models do deep-research-like work is to have them "First, create a plan to solve the problem, clearly listing the objective, approach, and output. Then follow the plan." #best-practices #future #prompt-engineering

  • Increase clarity, providing step-by-step instructions.
  • Resolve conflicting instructions.
  • Expand instructions to cover all scenarios and edge cases.

• Thu, Jun 19, 2025. For all AI code, review it, learn from it and share learnings. That prevents bugs AND we learn in the process. Ref #ai-coding #best-practices #code-agents #future #github #optimization #learning

• Mon, May 12, 2025. I was asked how to improve speed when building an enterprise ChatGPT clone using an API. Here's what I'd suggest, in order: #best-practices #chatgpt #optimization #prompt-engineering
  • Streaming. High impact, low effort.
  • Caching RAG retrieval as well as generation. High impact, low effort.
  • UI tweaks. Loading / streaming icons and progress hints ()"Retrieving context", "Generating answer", etc.)
  • Parallelize, if possible
  • Use model options where available, e.g. speculative decoding, models with higher speed, models with closer CDN, etc.
  • Shorten prompts
  • Persistent HTTP/2 Keep-Alive. Low impact, low effort (tweak server settings).

• Wed, Feb 5, 2025. Lessons from discussions at IIT Madras: #best-practices #lesson
  • Even in recorded video tutorials, asking students a question and pausing to give them time to think can be effective.
  • When you put students in front of real clients, engagement increases dramatically.
  • Most teaching assistants would like to help diligent students among the bottom half (more than the top decile of students).
  • However, there is a fraction of poor performers who do not care, and are best ignored. Their engagement and effort is a good measure of their interest.
  • Defining a minimal set of principles that we want to teach helps us measure if we've helped the bottom half at least meet those objectives.
  • Teaching is hard. Even after explanations, students, even ENGAGED students, tend to make basic mistakes

• Fri, Jan 17, 2025. Doctors can only do so much. Air quality, where you live, etc can do more for the patient than medicines or the doctor. If doctors keep this in mind, they can be more effective. #best-practices #future #optimization
  • Extending that thought, ANYONE who leverages assets through holistic thinking, becomes FAR more effective.

  • Consistent rule enforcement
  • Rewarding merit
  • Leadership by virtue and character

• Thu, Dec 12, 2024. I asked the Straive Digitalized Operations team what management techniques they would apply to manage LLMs. Here are the responses: #automation #best-practices #llm-ops #optimization #prompt-engineering #ask
  • Ask better questions. (Prompt engineering.)
  • Create templates or step-by-step instructions. (Chain of Thought.)
  • Ask for multiple options and pick from the best options. (Agentic approach?)
  • Training. (Fine tuning.)
  • Price weaker responses lower. (Stratified model pricing?)

• Wed, Nov 27, 2024. With LLMs, fostering innovation is a new path to profitability. Companies are increasing innovation team sizes. Productionizing that is the next. Some initiatives are: #best-practices #llm-ops #optimization
  • Convert popular demos into starter kits
  • Create and evangelize trainings on solutions and solution techniques
  • Create larger pools of capacity to build innovation and productionize it

• Mon, Nov 4, 2024. Creating a LLM-as-a-Judge That Drives Business Results by Hamel Husain. #best-practices #dev #llm-ops #prompt-engineering
  • Get THE domain expert (or approver) as the tester.
  • Create a dataset that is DIVERSE.
  • Covers EACH combination of:
    • Features
    • Scenarios: e.g. multiple matches, no match, ambiguous request, invalid/incomplete input, unsupported feature, system error
    • Persona: e.g. new user, expert user, non-native speaker, busy professional, technophobe, elderly user
  • Generate data using existing data + synthetic data for each SPECIFIC combination of the above
  • Evaluate based only on PASS/FAIL with a CRITIQUE detailed enough for a new employee. Include:
    • Nuances: Something a failed response did well or a passed response didn't quite do well
    • Improvements: Suggest how model can improve
  • Build an SPA to make it easy for the domain expert to review

• Sun, Oct 6, 2024. Parables on the Power of Planning in AI: Giving models about 30 seconds of thinking time consistently improves results - as much as increasing parameter size by a factor of 1,000 to 100,000! #best-practices #optimization #prompt-engineering #learning
  • This works particularly well for verifiable results (code, math, etc.)
  • Technique: Ask an LLM hundreds of times at low temperature and pick the most common one. (Google's Minerva used this on the MATH dataset.)
  • Better Technique: Ask an LLM hundreds of times. Pick the best solution based on an evaluation metric (reward model)
  • Better Technique: Apply a reward model at EACH step of the process. OpenAI's "Let's Verify Step by Step"

• Sat, Sep 28, 2024. API coding best practices Source via Simon Willison: #best-practices #github #prompt-engineering

  • Always add every example. Human think in examples.
  • Avoid defaults and be explicit unless 99% of the usage is with the default.
  • Make the feedback loops incredibly fast.
  • Make deprecations easy for users to deal with.
  • Keep objects immutable.

• Tue, Jun 25, 2024. LLM Patterns include Evals, RAG, Fine-tuning, Caching, Guardrails, Defensive UX, Collect feedback. Notably: #ai-coding #automation #best-practices #future #llm-ops #optimization #prompt-engineering

• Fri, Apr 12, 2024. Prashant Pandey: we need to prepare before every meeting. Something to teach #best-practices #future #lesson

• Sun, Mar 31, 2024. How I write podcast. Paul Graham essays #best-practices #write
  • Write simply. It helps communicate. (Don't concise if communication worsens.). It forces you to make the idea better
  • Do lame stuff. Else you won't start. Low standards drive creativity
  • The more to delete, the better your writing. Read your piece. Highlight what feels poor. Fix it. Ask friends to highlight what's BORING? UNCONVINCING? Delete the first, brainstorm the second. Or ask, what's the 10% to cut and 10% to keep.
  • Write about stuff you don't know above the. Writing GENERATES ideas
  • Write about what's BUS. GENERAL and SURPRISING. (Laughter is a sign of comprehension.) Do HARD things to cultivate taste.
  • Spend more time with people who generate ideas in you. Ravi chithappa. Ram. Ankor. Ganes. Books!
  • Build taste. I have a taste for picking technologies. Data visualization. Retrospect. Write down what you like and dislike. Copy what you REALLY like. Guilty pleasures.
  • A benefit of lower standards is that it let's you pick the path less travelled.
  • ITERATE. Discuss ideas. Iterate. Acknowledge. ITERATE.

• Tue, Mar 19, 2024. Ways to use inversion #best-practices #dev #future #prompt-engineering #prediction

  • Consciously where the six thinking hats or look hard for the silent voices in your head and express them
  • Ask children. They tend to think of more creative and childlike solutions
  • He converted a hiring process into a contest
  • Constantly ask yourself. What if every assumption I'm making about this is wrong?
  • Scenario planning is really about this. List a few scenarios. They'd have high impact or high probability. What happens in this scenario? Ideate

• Mon, Jan 15, 2024. How I write podcast. Tim Ferriss #best-practices
  • High bars are constraints. I set the strongest constraints against the scarcest resources. Like reputation
  • Being a category of one is more defensible than a competitive advantage
  • Content always beats presentation. When in doubt, push for more interesting content
  • Regular publishing improves thinking
  • To build a habit, do less than you think you can do. That makes it easier to build momentum on the habit and sustain during crunch times
  • There is a lot of mediocrity in the world. If you're doing something (in a winner take all ecosystem), be the best.
  • Top lawyers are exceptional proofreaders. They are able to see what is unclair, and what is redundant, and what has loop holes very quickly.
  • Forcing yourself to cut down from a thousand words to 200 to a paragraph to a sentence takes you through a phase transition where you discover something unexpected
  • The more outrageous the question, the more likely it is to be useful in generating a new perspective
