TLDR built a Chrome site blocker that lets you into distracting sites only after you do some math or simple coding (JS only right now). Direct link to extension (the site just gives you more context): https://chromewebstore.google.com/detail/sphinx-earn-your-di... Philosophically it's a speed bump rather than a hard gate, because you'll eventually tear a gate down but you'll leave a speed bump. I've always eventually removed site blockers, or just had them become a nuisance that I reflexively dismiss before getting to distracting sites. Site blockers don't really reduce the "start navigating to a distracting site" muscle memory, and they eventually just become annoying. Dopamine is a hell of a drug. At the same time, I've been getting frustrated that my intermediate/advanced math skills have atrophied, and becoming more senior in my career (plus AI...) has caused my coding skills to atrophy even further.

u/Potential_County1505 · Reddit
Looking for honest feedback Looking for honest feedback Hi everyone! I've been building NeuroLens AI, an AI companion for ADHD & perimenopause, and I'd love your honest feedback. It helps track focus, mood, sleep, stress, brain fog, and other symptoms, provides personalized AI guidance, and generates reports you can share with clinicians. It's not a diagnostic tool—it's designed to help people better understand their health patterns. Try it: https://neurolens-ai.com What would you i

Log dreams and discover recurring patterns with color-coded charts.

I built Dreamotif, a private dream journal that calculates what keeps coming back. No AI. Dreamotif is a private journal that calculates the motfis - the recurring themes and elements in your dreams - the motifs. You can try it at Dreamotif.com I used to log my dreams in a Google Doc with a color-coded key at the top listing the different things that kept showing up. A blue highlight for water, for the bodies of water that used to be a very common element of mine. Brown for
