• Hacker News1How I use Claude Code: Separation of planning and executionThe author describes a structured AI coding workflow used with Claude Code for 9 months. The key principle is never letting Claude write code until reviewing and approving a written plan. The process involves: 1) Research phase where Claude deeply studies the codebase and writes findings to research.md, 2) Planning phase creating detailed plan.md files, 3) Annotation cycles where the author adds inline notes to refine the plan through multiple iterations, 4) Todo list creation for tracking, and 5) Implementation with specific prompts. This approach prevents costly failures like code that works in isolation but breaks surrounding systems, maintains architectural control, and produces better results than direct prompt-to-code workflows.Planning vs execution phases in AI coding:The core debate centers on forcing LLMs to surface assumptions before coding through detailed planning phases. Users discuss whether written plans help debug invisible assumptions about architecture and constraints, or if this is just "superstition" and cargo cult prompting.Prompting techniques and model behavior:Discussion about whether words like "deeply" and "in great detail" actually influence LLM output quality, with theories ranging from attention mechanisms to training data patterns. Some view it as effective technique while others call it magical thinking.Workflow approaches and project structure:Users share detailed methodologies involving specs, plans, status files, and multi-agent approaches. Focus on managing context efficiently, breaking work into phases, and maintaining project documentation to guide AI implementation.
• Reddit science1Using scented products indoors changes the chemistry of the air, producing as much air pollution as car exhaust does outside, according to a new study. Researchers say that breathing in these nanosized particles could have serious health implications.Using scented products indoors, such as flame-free candles and wax melts, can create significant indoor air pollution comparable to car exhaust. Research by Purdue University found these products release nanosized particles that can penetrate deep into lungs and potentially enter the bloodstream, posing serious respiratory health risks.Misleading title scope:Discussion about how study only focused on wax melts but title suggests all scented products, with debate about whether findings could logically extend to other scented itemsHealth concerns from chemist:A chemist's perspective against using scented products leads to sharing of personal health impact stories, from COPD to cancer cases, and debate about necessity of artificial scentsAir purification solutions:Discussion of HEPA filters and other air purification methods as solutions, with debate about effectiveness against different types of pollutants like VOCs and nanoparticles
