We already have flying cars; they are called helicopters. I'm not sure you want to live in a neighborhood that has people commuting by helicopters; it would be very noisy.

Want an example of crazy cool shit we just accomplished? Covid vaccine. Creating a vaccine/testing in less than a year and now distributing it at such a massive scale will likely go down in history as an event akin to the Manhattan Project.


Hey! That "music major" must have at least been well connected! She was just "managing" people anyways; not like she needed to know what she was doing.


Yeah but I bet they don't test the engine by throwing the turkeys in while its actually flying. Could easily be bird strike broke a fan blade that damaged the outer cowlings enough that they broke off/apart due to airspeed. From what I understand these engines use a unique hollow fan blade; so it could also just be an early/unexpected failure.

I wonder why you would freeze the turkey before throwing it in. Surely their aren't frozen birds that size flying around. It's like shooting a man.. before throwing him out an airplane.


They froze the turkeys to make them easier to fire out of their pneumatic cannon at several hundred miles per hour. (I saw this on a documentary about the 777 on TV, and I can't find the clips on YouTube).

The compressor blades hardly seem to notice. They are shot out of the rear of the engine as a pink mist.

Birds do stop engines. You just need to fly through enough them. Flight 1549 lost both engines while turning Canadian geese into deli slices.


Obligatory "Canada Geese", not "Canadian Geese" comment.

I'm curious: do we know how many geese it takes to take out an engine?


History tells us it is far better to let Martians govern themselves. The colonies would eventually rebel regardless; might as well embrace it and let them dictate their own laws.

That being said. Guns on mars! GUNS ON MARS!!! They have a rIGHt to hunt space deer!


I agree that any Mars colony should very quickly become independent.

However, I think we should wait until there are enough people on Mars that there can be a small representative government (or other form of government that they would choose).

Mars shouldn't be independent when the first 10 people land on the surface of the planet.

This tos item has always been my biggest complaint about Starlink. I shouldn't be forced to take a position on premature Martian independence just because I hate Comcast.


This is someone semantics anyway since there will be no enforcement mechanism in the beginning from Earth to Mars. People on Mars will just do whatever they want.


That doesn't seem accurate to me.

Let's say you're in the _first_ colony ship that lands on Mars. 12 people disembark from the vessel.

There are resources available for 5 years on the planet from prior cargo runs.

All future cargo will be launched from Earth, and very likely from territory controlled by large and powerful governments. All those flights require mission approval to launch and resupply.

Are you _sure_ there's no enforcement mechanism that Earthbound authorities can apply to the Martian people?

I actually think independence for Mars quickly (but not immediately) is important exactly _because_ the Martian people will be able to be so easily held hostage by the whims of a few Earthbound governments.


My point only applies to a colony that is functionally independent.


> I shouldn't be forced to take a position on premature Martian independence just because I hate Comcast.

We really do live in the future!


> I agree that any Mars colony should very quickly become independent.

Why do you think so? Wouldn't it be better for them to be Earth dependent?


> Wouldn't it be better for them to be Earth dependent?

Mars very likely would be dependent on the Earth for trade and resources for a long time. It will be a long, long time before it becomes totally self-sustaining.

But, in terms of their government, I generally believe broadly in the principle of local self-determination. I think that will and should apply to Mars, once the population is sufficient.


For them? Probably not. When has anyone else made big decisions for you than you made for yourself?


Mars will be independent until they discover vast deposits of space oil, at which point George W Bush's son will continue his family's war mongering and invade


Does history have any footnotes about self sufficiency?


Guns don't kill people. Holes in domes kill people.


This is the coolest part of the mission IMO.

My big question is where does it land? Does it dock with the rover? It seems to power itself via a solar array. About 100 days into the mission they plan on launching the helicopter for the tiny lifespan window.

I think the limit on its lifespan is really, "How long until destroyed by wind/dust". And then how long until it cannot charge its own batteries/sustain itself.


I agree, this is the coolest part, but the most useful part for humanity is MOXIE.

It lands on the ground. And yes, dust on the panels is a big concern. (I work at JPL but not on Perseverance / Ingenuity)


That's really cool; thanks for your work!!

I cant wait to see how Y'all figure out how to get those rock samples back to earth; that's gonnna be nuts XD


>Elon Musk has strong parallels to Trump's appeal.

Isn't that the strangest thing? If you watch videos of Elon he is no where near as charismatic as trump.

I think it mostly stems from his success with SpaceX and earning accolades for being, "The Guy who does Impossible things". His having a car manufacturing company with an impossible share price just make sense.


I think the similarity is less their personalities, and more in their use social media for shock value and attention, and the quasi-religious devotion of many of their supporters.


So you would memorize a master password and then hash it + the websites name?

Just sounds like a normal password with the same amount of steps.


If the password is ever exposed via a breach, generally smart people can pick up on that pattern and then all of your passwords are cracked.

There are ways you could alter the pattern, maybe a separate short salt for each site in addition to the domain, so all you need to remember is the salt, like "dog" for pets dot com, that could make it a bit more secure. Or vary how you combine the master PW and the domain (i.e. count the number of letters in the domain and insert the domain starting with that number, or each letter of the domain that many characters appart embedded into the master PW.)

Or...just use random passwords, a password manager, and make sure you both trust the provider of the password manager (or use one you control) and use a super high security password as your master password in addition to other forms of authentication. And never let it allow you to stay logged in to your password manager.


I personally use a password manager except in a few physical cases where I use the function approach or have just directly memorized the PIN (iPhone, YubiKey pre-fingerprint).

The function approach is a normal password, just that it scales O(1) with your memory for O(N) passwords. The expectation is that if you have a complex enough function it will be non-trivial to back-fit it, this doesn’t necessarily hold for any arbitrary function, of course.


I'd just like to point out that the taboo against murder has been around for far longer then the Bible or likely any religion that exists today.

The Code of Hammurabi predates it by 1700 years(almost 4000 years ago). Not allowing murder seems good for the survival of any society of humans.


We already use fusion. There is a giant fusion reactor hanging in the sky where almost all energy since the beginning of our time comes from.
