SlouchSniper: AI Posture App
SlouchSniper uses on-device computer vision to monitor posture via webcam and dims your screen when you slouch, restoring it when you sit up. A behavioral nudge approach to building postural habits — no cloud, one-time purchase.
Outlive by Peter Attia — Derek Sivers' Notes
Derek Sivers' notes on Peter Attia's book Outlive — about the science and practice of longevity, with Attia's framework for extending healthspan not just lifespan. Attia argues for earlier, more proactive intervention than conventional medicine recommends.
f.lux, but for your house — Whole-House Circadian Lighting
Tyler Cipriani's guide to implementing whole-house circadian lighting via Home Assistant — warm amber light in the evening, bright cool light in the day, all automated. f.lux for every bulb in your house.
Power: Clinical Trial Access Platform
Power is a clinical trial matching platform making trials accessible to any patient who needs them, not just those with top doctors. The bet is that better trial matching improves both patient outcomes and trial recruitment — a dual-sided market problem in healthcare.
How to Maximize Dopamine & Motivation — Andrew Huberman
Andrew Huberman's deep-dive on dopamine: how to maximize the molecule that drives motivation, not just pleasure. The key insight is that dopamine is released in anticipation (pursuit), not just upon reward — with practical protocols for maintaining the system.
The Beginner's Guide to Intermittent Fasting
James Clear's beginner's guide to intermittent fasting — covering the 16:8, 24-hour, and 5:2 protocols, the research behind them, and practical tips for getting started. A clear summary from the author of Atomic Habits.
Effects of Intermittent Fasting on Health, Aging, and Disease
A comprehensive NEJM review of intermittent fasting research synthesizes animal and human evidence showing broad metabolic, neurological, and anti-aging benefits from periodic caloric abstinence independent of overall calorie reduction. The mechanism centers on a metabolic switch from glucose to ketones that activates evolutionarily conserved cellular stress-response pathways.
Effects of Intermittent Fasting on Body Composition and Clinical Health Markers
A review of clinical evidence on intermittent fasting protocols (alternate-day, whole-day, time-restricted feeding) and their effects on body composition and health markers. Finds comparable fat loss to continuous calorie restriction with possible lean-mass preservation advantages.
15 Hip Stretches for Tight Hips
15 hip stretches from a certified trainer — covering the hip flexors, glutes, piriformis, and IT band for people with tight hips from sitting. Practical reference for a common sedentary-work complaint.
The IV Doc
The IV Doc — an on-demand intravenous drip service for rehydration, saved in response to a joke tweet. A cultural artifact of the 2014 San Francisco startup-and-excess moment.
Everything You Know About Fitness Is a Lie
Men's Journal's contrarian take on popular fitness wisdom — debunking common beliefs about cardio, stretching, and weight training. Representative of the early 2010s evidence-based fitness movement that challenged conventional gym wisdom.
Your Body's Best Time for Everything
WSJ's guide to chronobiology and optimal daily timing — when your body is physiologically primed for different tasks. Exercise, creative work, analytical thinking, and sleep each have distinct peaks driven by circadian rhythms and cortisol/melatonin cycles.
What Happens to Our Brains When We Exercise
Buffer's synthesis of neuroscience research on exercise and mood: BDNF and endorphins explain why exercise produces mental clarity and euphoria, and timing matters more than volume — 20 minutes on the day you need it beats a missed workout in a weekly routine.
The Hidden Truths About Calories
Scientific American on the hidden complexity behind calorie counting — how the Atwater factors used on nutrition labels are crude approximations, how cooking changes caloric availability, and how gut microbiome composition affects calorie extraction. The 'a calorie is a calorie' model is much messier in practice.
Value of Genomics and Personalized Medicine Is Wrongly Downplayed
UCSF researchers pushing back against a widely-reported study claiming DNA's power to predict illness is limited — arguing that the value of genomics for personalized medicine is being systematically underestimated. A 2012 snapshot of a debate that's still ongoing.
f.lux: adaptive screen color temperature
f.lux adjusts monitor color temperature throughout the day — warmer at night to reduce blue light exposure. One of the earliest widely-adopted tools for circadian-aware display calibration, predating OS-level Night Mode by years.
