What it does

Jet Zzz turns your flight itinerary, sleep habits, and meetings you can't move into a day-by-day plan for sleep, light, and caffeine — exportable to your calendar. Multi-leg routes and layovers are handled. Eastbound and westbound trips are scheduled differently because the body shifts asymmetrically. No account, nothing leaves your browser, free, 9 languages. Built by one person, for travelers who want to arrive adjusted instead of wrecked.

Beat jet lag with a personalized sleep and activity schedule. Plan your adjustment before, during, and after flights.

Jet Zzz is a free, browser-based jet lag planner that builds personalized sleep and activity schedules for travelers crossing time zones. Enter your flights, set your sleep profile, mark fixed activities, and get a day-by-day plan you can export to your calendar orfrom jetzzz.app

Homebrew 6.0.0▲1,481
Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
