So I ordered a Samsung Note Ultra from Google Fi via expedited shipping signature required. When it is supposedly delivered the signature confirmation from Fedex claims it was signed for by 'C.NINETEEN'. Google then proceeds to immediately deny my claim for a refund of the ~$1000. Pretty nice scam these two are running?
Correct! If you play with the source on codesandbox you can disable the demo mode and actually rotate the Kollsman window using the BARO button. The calculations for pressure and resulting altitude are from standard physics texts.
I wrote these a while ago with some intention of creating flight training tools. I'm making them available to all the other programmer / pilots out there who might find them useful. https://codesandbox.io/s/six-pack-flight-instruments-fl7b8
Stop posting physics articles on hacker news. Just because everyone here has watched too much Star Trek and Star Wars doesn't mean we actually understand a single solitary shred of this stuff...although it sounds cool.
