Android @ Dropbox
summary
Carousel switches to 75px quick thumbnails on the UI thread and queues 250px decodes on a background thread so decoding stays under Android’s 17ms frame budget and the app avoids gray tiles at 60fps, with 250px decodes taking ~10ms each on Nexus 4 class devices. The desktop connect flow generates a 24-byte token in memcache embedded as QR codes in the page, scans on phone to deliver a personalized few-hundred-kilobyte installer and auto-login, and is validated with 1% experiments and hackweek prototypes.
