This guy was in a remote controlled, parachute equipped gondola at 17km altitude wearing a pressurized suite. His suit broke and even though the emergency descent of the gondola was immediately activated to descend safely, he later died from embolism (bubbles forming in the blood because of rapidly decreasing pressure). Passenger jets cruise at about 11km so i gather it would be similar.

that is not a power plant. a power plant supplies power…

What makes them think that the library of Alexandria did it any other way? Nerds have existed long before the internet…

also: you can calculate the carnot cycle efficiency of a solar cell as if it was a classical heat-power-machine, even though it has no visible moving parts.

the reason why this works and yields realistic results is because the basic principles of thermodynamics stay the same no matter if you are working with steam, combustion gasses or photons and electron gas inside a semiconductor.

downvote for lack of feathers. smh.

its real, though not necessarily the type of window that you described. also exists in Turkish. i have a Turkish colleague who was very proud to explain the origin of that word to us in Germany :D .

this is extra tricky because they did not specify the exact kernel. mainline could be any of the kernels tagged as stable that you can build from linus' git tree. i know that in the past you could run a mainline linux on intel 368 chips but today you probably can not because official support was dropped a while ago.

your text seems to agree 100% with one of the examples in the original posts text: ”[…] immigrants who […] simply sought better lives for themselves and their descendants“.

could you elaborate why you think it is wrong?

yeah this is a real pet peeve of mine.

In German many people, web mailers and also sometimes even email software use "AW:" (short for AntWort) instead of "Re:" and then some of them don't even recognize the existence of a previous "AW:" or "Re:" giving you such wondrous email subjects as: "AW: Re: AW: Re: AW: AW: Re: AW: Re: really important subject" 🤦

Looking at the price per kWh for commercial batteries tells me that we are seeing the battery revolution right now.

Graphene is already commercially used in some applications:

There are already very effective cures for some types of cancer (note that the differences between the many types of cancer can be huge and so the effort and time needed to create cures will also be very different. some treatments also are effective but not completely understood yet, like for bladder cancer)

Nuclear fusion devices are commercially used in material analysis (mostly in the semiconductor industry and in ore processing). There are different types in use – some even use thermonuclear fusion on a small scale.

It all seems like super crazy superconductor level tech until it becomes mundane and part of peoples lives ... then we stop noticing how amazing it really is.

JXL rocks! Its so sad that some browser vendors are seemingly trying to kill it. It has basically all the features you could want for a JPG replacement and also has a reference implementation that implemented all that stuff as free software and with good documentation without any patent bullshit attached.
