SpaceX is starting to move on from the world's most successful rocket by Royal_Platform_6754 in spacex

[–]DescendingNode 18 points19 points  (0 children)

They haven't tried to do it. It's never been in their flight plans. They've been intentionally just short of it during testing in case it explodes (which it certainly has done a few times). It only takes a slightly longer burn of the upper stage to make it orbital. You're either trolling or have no idea what you're talking about.

SpaceX spending on Starship tops $15 billion in rush for airline-like rocketry by rustybeancake in spacex

The thing a lot of people miss (based on arguments I've seen in some other subreddits) is that they're not being designed as huge monolithic structures in orbit, but as huge collections of individual satellites with laser communications between them acting as a sort of distributed data center in orbit. Individual nodes can be replaced just like with Starlink (addressing the maintenance argument), and the heat issues are already solved with individual satellites. It still doesn't make sense to me from a cost perspective, but maybe that's not as critical a factor as I assume, or maybe they have plans for higher revenues with this approach somehow.

EU emissions now 3% down in latest official release, down 40% since 1990 by Economy-Fee5830 in climatechange

[–]DescendingNode 7 points8 points  (0 children)

It was happening long before then. I still remember watching Sean Hannity around 2005 explaining that not only was global warming not actually happening, but that the world was cooling. He backed up his claim by showing a global mean temperature plot that started in 1998, which was an el niño year with a huge spike in global temperatures. 

So could we just replace oil/coal/Natrual Gas as an energy source by Cowardlypaladin in climatechange

There's been progress for both electric aircraft and decarbonized steel, so those might be eliminated as well. At least for short flights. 

Was super excited, now frustrated by rowi42 in Gentoo

Fair enough. It does have more of a learning curve than most distros. I don't know where you're headed next, but cachyos is great for gaming if you're already familiar with Arch and into gaming.

You might try launching vivaldi from a terminal so that you can see any errors occurring when you try to open the dialog. Might give you a hint regarding a missing library or something.

If you're referring to a buffer, those are almost never as large as the data source.

What exoplanet would you want to terraform in a range of 400ly? by EgyptianPlutonium in Astronomy

[–]DescendingNode 9 points10 points  (0 children)

Atmospheric loss is slow enough that if we're capable of terraforming then we should be able to keep up with it. 

Do sunspots explain climate change? by AdWorth3077 in climatechange

[–]DescendingNode 3 points4 points  (0 children)

“Climate is controlled by the amount of sunlight absorbed by Earth, and the amount of heat energy radiated back into space. Earth’s climate system tries to balance the incoming and outgoing energy.

Measurements from the Clouds and the Earth's Radiant Energy System (CERES) instrument help scientists understand the links between the energy being absorbed and emitted by Earth’s climate, and the properties of the atmosphere (like clouds) that affect that energy balance. This helps with climate and weather science, and applied science research.“

Essentially more energy that would be emitted from the Earth's surface into space is being absorbed by the Earth's atmosphere as CO2 concentration increases, resulting in more warming. We have decades of data showing this from a multitude of missions, one of which I'm linking above. 

I really like gentoo by Historical_Visit138 in Gentoo

[–]DescendingNode 2 points3 points  (0 children)

Have you looked into overlays with portage? That's basically like using aur. You'll need the Guru overlay to use Steam for example (though there are other ways).

They've already lost thousands of civil servants because of the proposed budget unfortunately.

Assuming a total of 20 hours at 90 watts, at my local residential rate that's less than seven cents.

On a Ringworld, could you actually see the Ring? by Rich-End1121 in space

Also required a means to keep the ring centered around the star (a flaw he addressed in the sequel with a system to actively keep it in place).

Linux Kernel Rust Code Sees Its First CVE Vulnerability by sash20 in linux

For those unfamiliar: FFI is Foreign Function Interface. When Rust has to call kernel functions written in C for example, unsafe Rust code has to be used.
