A "short boat ride" you say... Current exclusion zones and logistical requirements suggest otherwise.

Realistically, P2P using giant rockets is a nothing but a pipe dream. Just straight forward things like weather proof this. The latest F9 launch had to be scrubbed two times due to unfavourable weather at the launch site, for example.

Now multiply that just that weather-risk by two, since the landing site also requires good conditions at the same time.

Then there's the "little things" like airspace closures, launch permissions, boarding procedures, the requirement for personal pressure suits (simple masks won't do in case of cabin pressure loss), etc.

The idea sounds so easy on paper, but there's a lot of good reasons that in over 60 years of crewed space flight, the idea hasn't even been demonstrated.

Sorry, it took me a bit to reply to you on this censorship laden bullshit “you’re replying to fast by posting more than 3 times a day” website.

Fuck dang, time to cycle residential proxies.

That said, see sibling comments about fineness. In addition to being fine in the shiny variety, starship is a portly fellow. It will be able to land in anything less than a hurricane.

Apple Users only. Responses are not necessarily indicative of how the respondents will actually behave in real life.

Honestly I find most studies based solely on self-reported data worthless.

What people say they’ll do/buy is often only loosely correlated with what actually happens.

See:

-YouTube thumbnail controversy, vs what people actually click on

-/r/apple and other comment section’s obsession with the commercially-failed mini lineup of iPhones

-everyone says ads don’t work on them, but ads work

I could go on

Isn't synology running it hybridized with their own proprietary storage layer?
zionic · 3 years ago
It's not proprietary, you can hook up the drives to a linux box and pull files off them just fine if your box dies. I've never had to do this, but I've seen others say they've done so successfully.

what’s the seat-kilometre fuel burn on this compared to sub and supersonic jets?
zionic · 3 years ago
Should be much better, you spend most of the time coasting and most of your acceleration in very thin atmosphere, vs a plane that has to cruise down in the soup.

Also, starship has more pressurized volume than a 747. You can fit a lot of people.

And would such craft be allowed to launch from your average airport?
zionic · 3 years ago
A short boat ride off the coast is all it will take to get form NY to Tokyo in 40 minutes or less. Worth it.

If you’re healthy enough to withstand 3 Gs and they make rocketry about a million times safer
zionic · 3 years ago
E2E payload weight will be much lower than typical LEO configs, total altitude lower. You don't need to circularize etc etc.

This means you can spend more fuel/be less efficient overall for a much more comfortable acceleration profile.

In terms of safety, starship will fly hundreds, perhaps thousands of times before people fly on them. They'll get there.

Starship E2E (earth 2 earth) will make in-atmo supersonic pointless.

btrfs is a horrible mess that will likely lose your data. For the few production systems we implemented it on, every single normal failure that other file systems can recover from had resulted in complete loss. We've had to implement a project to rebuild all systems that used btrfs in order to remove it.

>btrfs is a horrible mess that will likely lose your data.

Meanwhile the bazillion petabytes on the world's synology NAS run fine, and are BTRFS.

Which will speed up issues with extremism greatly.

As opposed to the centralized extremism export machine we have now.

Do you want the owners of those small communities to get sued if someone posts copywrited material?
zionic · 3 years ago
If they don’t censor, they’re not liable. If they censor, they are liable.
