I believe the notification solution was a compromise with the cellular providers. They didn't want a whole bunch of devices holding IP connections open on their network. In the beginning even the notification channel Apple had was a negotiated capability and they still had to reset the connection at least every 24 hours. The early billing systems were each data connection was a call on the system. You could see in your bill about one data call a day with a boatload of data that lasted all day long.

The simple solution for you would just schedule a background task that runs every few minutes or so via a background push and if there are new messages issue an on-device notification.

Every metro region should establish it's own time zone with 1200 as high solar. Currently you'll see a huge bias of those on one side of a time zone wanting to stay on Daylight savings versus standard time. Smart watches and phones would have no issues tracking it. Calendars would be fine. Only significant issue I see is that meetings won't normally be on top of the hour if you aren't all in the same timezone.

Comment Learn where the battery cut-off switch is (Score 1) 193

People should definitely know where their HV battery cut-off is located. Model 3 had is under the back passenger side seat. Completely disconnects the battery from connections outside the battery pack. I suspect what happens is that it's occasionally engaged to charge up the 12V system. If the car is or has been submerged and when it engages the HV circuits that happen to be shorted from the salt corrosion you get a run-away thermal event. Throwing that switch prevents the contactor from engaging the HV.

Comment Got a script for that (Score 1) 133

I wrote a python script that does just that with a Sense power meter API and the Tesla API. Could only do a 90 second update period since the Tesla API would start to rate limit. Every 90 seconds it checks for more than 5 Amps of solar power are available (the minimum the Tesla API supports) and tells the car to chow down. Gives some stair stepping in the power production but I've had months where I've just driven on sunshine.

Comment Brainless Servers (Score 2) 81

I once built a computer system that needed to be easily sanitized after processing sensitive data. Nearly all the systems had no hard drive. Just a TFTP boot that downloaded the image from a single master node and ran the system off a RAM disk. The master node even had the drive mounted read only while in operation and we had a few of them so even if they took the drive we'd be back online in the time a reboot took. Once power dropped all data was lost. We debated even using a read-only DVD as the boot disk so there was no non-volatile storage in the entire system. Nothing to take and we were absolutely confident pulling the plug would sanitize the system.

Comment Switch to urban time zones (Score 0) 242

The real solution is just switch to urban time zones. Each metro area has its own timezone with noon at high solar for that area. Just like it was for the majority of human time keeping. Computers already use urban areas for time zones. Why are we tying ourselves down to an 1800's era system designed for trains.
