Abelbeck Aviation Checklist got another feature: it now supports multiple synchronised sessions. Based on server-sent events, changes in one session are committed to all other sessions of a user. In the future I can do the checklists on my smartphone fixed to my thigh, while the tablet nearby shows my flight planning. And both reflect the current state. Now I can again tend to the flight recorder part of my app. #aviationgeek #javascript #python #asyncio #serversentevents
