  • The security level should be the user’s choice. Maybe I don’t care if my neopets account is hacked. Maybe the 2fa offered actually decreases security, like the SMS 2FA required by my 401k account that can be used as the sole recovery factor, bypassing the password. Maybe I’m accessing from a system configuration that makes 2fa really annoying, like a build system running inside a fresh VM on every run.

    The service doesn’t have the context necessary to know when 2FA is warranted.






  • There’s multiple things you’re mixing up here. There’s the “up” in the global coordinate reference frame. This could be based on the local system, though that makes entering and exiting the system a tiny bit more difficult. More likely it’d be based on galactic coordinates.

    There’s also the ship reference frame in the comic. This probably won’t be oriented towards the global coordinate system. It’ll be oriented towards whatever the engines, sensors, and gravity need. Because the ships will all be in orbit, their orientations will probably be changing constantly relative to other ships and the global reference frame. There’s no reason to orient in a single direction and lots of reasons not to (it wastes energy, points your sensors away from the things you want to see, etc).

    Just did a quick eBay check. The cheapest 350hp ICE I could find was a rebuilt $3,000 Chevy engine. A new one is more like $6-8k. An equally powerful, brand new Siemens motor was $1,500.

    This makes sense when you think about it though. An electric motor is basically just steel with a bunch of coiled wire with some control electronics. An ICE is hundreds of pounds of precision cast and machined metal. The cost driver in electric vehicles is not the motor, it’s the batteries.
