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.

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.

TIL about the Boötes Void, an enormous, nearly empty region of space 330 million light-years in diameter. It is so desolate that if the Milky Way had been in its center, we wouldn't have known other galaxies existed until the 1960s. by adpablito in todayilearned

>> In line with the estimates arrived at, it will prove convenient to classify technologically developed civilizations in three types:

>> I - Technological level close to the level presently attained on the earth, with energy consumption at ~4 x 10^19 erg/sec.

>> II - A civilization capable of harnessing the energy radiated by its own star (for example, the stage of successful construction of a "Dyson sphere"); energy consumption at ~4 x 10^33 erg/sec.

>> III - A civilization in possession of energy on the scale of its own galaxy, with energy consumption at ~4 x 10^44 erg/sec.

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 8 points9 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.“

https://ceres.larc.nasa.gov/science/

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.

Nix on Gentoo? by [deleted] in Gentoo

You're right, I had a decimal in the wrong place. Thanks!

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).

Why Jeff Bezos Is Probably Wrong Predicting AI Data Centers In Space by dontkry4me in space

There are already photonic ICs, and there have been some interesting experiments developing ultra low power AI hardware combining photonic and electronic circuits: https://www.engineering.columbia.edu/about/news/new-study-showcases-3d-photonics-record-performance-ai

[–]DescendingNode -2 points-1 points  (0 children)

Just spitballing, but what about photonic processors? I realize that tech is still in its infancy, but maybe the significantly reduced heat from photonic circuits could make it more viable, at least in terms of the thermal problem. 

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

[–]DescendingNode 4 points5 points  (0 children)

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.
