Could you provide more info

Oath2 shouldn't aloow this. Also you say you're logged in as a Dev acct. Dev accts are sandboxed to the dev app ID.

Could you use Loom to show a video of this big?


For clarification, it's not a Facebook developer account. This is just a dummy account I've been using to verify the social graph headers are working when I post pages from an unrelated project. It's technically against FB policy to have an account that isn't a real person. This dummy user has no friends; my human friend has not interacted with it in any way.

I did post a partial screencap elsewhere in the thread. I'm not comfortable creating a video but I would be happy to provide further details to FB security folks.

For what it's worth, part of the reason I posted to HN was that it's clear to me that this is intended functionality. Bugs don't usually say "welcome back".

I believe that the risk associated with this feature dramatically outweighs the upside.


You’d expect such findings from an entity churning out corporate workers — MBAs

Reaching for large jar of salt


A Mars mission — even if you ignore the radiation danger has a massive engineering hurdles.

How does one land — decelerate to a safe landing. The amount of fuel required to fire a mars retro rocket is many times that on earth. Then you need to lift off.

Getting to mars is not the issue — landing and taking off is the major challenge.


I think you have that backwards? Taking off from Mars is significantly easier than earth because of lower gravity and a less-dense atmosphere.


How do you fuel the rocket on Mars?


All you need is oxygen and hydrogen. Both of those are actually plentiful on Mars.


And the machinery to gather them etcetera etcetera... Just because the raw material is there doesn't rocket fuel make. And I'd be hard pressed to say that oxygen is plentiful on Mars. There is some oxygen.


"And the machinery to gather them"

That machinery can be sent gradually and ahead-of-time.

"Just because the raw material is there doesn't rocket fuel make"

No, but it means that such fuel is at least possible.

"I'd be hard pressed to say that oxygen is plentiful on Mars"

The current understanding is that there's millions of cubic meters of water ice on or near the Martian surface (with even more suspected further beneath the surface). Sounds pretty plentiful to me.


Neither of those are plentiful on Mars.


Mars has lots of water ice, which is made (almost) exclusively of - you guessed it - hydrogen and oxygen.

So yes, both of those things are plentiful on Mars. Maybe not to Earth standards (or the standards of, say, Ceres or Enceladus), but certainly abundant compared to our own moon (at least as far as current information tells us).


It's all relative. If you already have enough energy to crack water, fueling a rocket is not a worry.


Carnatic, Hindustani?
