My grandma is recovering from a recent viral infection that has necessitated the use of a BiPap machine for extended periods. Today, while I was visiting her, the clip on her face mask fatigued. We could've bought a new mask tomorrow for ₹3500 (~$50) but that seemed unideal.

First off, the R1 is absolutely an Android app. It is actually three applications sitting atop the Android Board Support Package from MediaTek: - RabbitIme.apk - R1SystemUpdater.apk - RabbitLauncher.apk There are no system level modifications, and it even ships with stock apps.

The reason it was trivial to get the app running on any android device was because Rabbit didn't initially bother checking the headers being sent from the device. It appears that the first batch devices were shipped from the factory with ADB enabled.

We were able to dump and analyze the firmware. Because of their implementation, the only way for an old device to communicate with the server is to do an OTA. Patching the existing tools to apply a delta OTA to a base image was the hardest part of the project.

We had issues with applying a delta payload to the image, b one of the gang actually ported go-payload-dumper to work with delta updates! Once that was done, it was just a matter of applying the update, and pulling the new launcher app.

@jsngr While this is an interesting demo, I feel like it’s a very superficial representation of what ‘design’ is. Is it replacing the dude who makes generic mock-ups? Likely. But is it replacing the person who is actually building their interface for the user? Hard to say.

What does the roid–bro mindset to tree growth look like? Seeing them as 'sacred' reduces debate to 'pro–green' or 'pro–infra' (often a choice to be made in cities) We should be enhancing tree growth to absurd levels, going from sapling to maturity in years instead of decades.
