Michael VealeThe seasonal news that #WhatsApp will stop working on #iPhone 5 and below #Android 4.3 highlights how the lack of Web apps is a significant environmental problem. Phones become obsolete in part because they don’t get OS updates, and they become incompatible with compiled apps. A lightweight OS for old phones would be more feasible if it mainly had to have a solid Web browser that facilitated a proper selection of #ProgressiveWebApps (& if manufacturers made open drivers/docs). #PWA #PWAs
jon crowcroft@mikarv browsers use very little of the OS ant more frankily 4.2BSDunux would do fine (that's a 1981 OS with syscall mostly the same as OSX as far as anyone should really care)
@tforcworc but PWAs rely on interfacing with the device through the many web APIs, calling sensors etc…
@mikarv maybe ask brad Karp or hamed about how sandboxing inside browsers works...
