Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      Not a web browser thin client. VNC-like. All data remote, optionally on hardware on your own physical premises. Every device is a burner.

      Not only do you eliminate searches & make replacement of potentially compromised devices trivial...

      You also kill everything cpu-hungry that precludes Nokia-candybar-era battery performance.

      Same screen power costs and increased usage of networking. It's likely going to end up using more power if it's as functional.

      It's not heavy CPU/GPU usage for calculations/rendering that ends up draining most power on mobile devices outside of gaming.

      Better gaming battery life that way, definitely, but not without significant latency that can't all be eliminated.

      Input latency is also becoming a major concern even outside of gaming. Can't see this happening. All data on servers, yeah.

      Not UI / rendering on servers though. And it's hard to see it as anything but backwards progress on security/privacy.

      Intended usage case has the server as a physically-secured box in home or office, not somebody else's cloud.

      An unattended server with inferior encryption and data at rest properties isn't exactly an improvement.

      You keep saying "inferior encryption". No idea why.

          It's inherently worse in that model particularly if the server isn't a slave of the phone that drops the key based on phone use.

          It loses nice properties an impl can have that's on-device and the server could be in attacker control when the user unlocks.

          Your threat model seems really warped & out of touch with the reality of how vulnerable Android devices are.

          You're the one with warped perceptions, bias, lack of experience, and lack of threat modelling.

          Attacker breaking into home/office & successfully tampering w/phys tamper-resistent server != normal person's threat model.

          Device seizure at border or traffic stop & browser-sandbox-escape drive-by malware OTOH are in normal person's threat model.

          This doesn't do anything to mitigate either.

          Seizure is completely mitigated by having no data on the device.

      Loading seems to be taking a while.
