JET's final nuclear fusion experiment produced a record-breaking 69 megajoules of heat. Nice. "Some like it hot, but you can't tell how hot 'till you try"
"Released over six seconds from only 0.21 milligrams of fuel, the energy record equals the energy released from burning 2 kilograms of coal." (from a different article on this event). <-- I guess you have to start somewhere. All for only 700-800MW input. So, in 30-50 years—when they get this perfected—we'll be set!

Last time I checked solar and wind are both clean energy. Wind doesn't require those huge windmills but can be added just about anywhere.

Neither solar nor wind are consistent enough sources of energy in most locations to match current demand, much less our ever-increasing demand for power. And they aren't completely clean or without their own negative environmental impact.

No power source is without negative environmental impacts. Fusion won't be either. As for intermittent production, that's what batteries are for.

Sudo for Windows is a new way for users to run elevated commands directly from an unelevated console session. It is an ergonomic and familiar solution for users who want to elevate a command without having to first open a new elevated console. Now it's official you can get a sandwich
Kind of a duplicate, but this is the official announcement, so I figured it would be worth posting
Also, apparently it works on Win7 and up, if you can get it off of a Win11 machine

runas /user:<admin account=""> has been part of Windows for over a decade.

It is troublesome to keep typing my password when on the other hand, running my cmd.exe in admin mode and clicking Ok on the UAC prompt is easier and hassle-free. If there is a keylogger running on your system after login, hacker can get your password.

But, can I have a vertical taskbar yet[^]?
Since they're stealing ideas from Linux (orig. Unix), my Ubuntu 22.04.3 LTS allows vertical task bar and I'm using it now.
So maybe they'll steal that idea soon.

They *had* the idea (back in Win7), but lost it in all the "progress"

How do you ban a device built with open source hardware and software anyway? Now they're banning dolphins?

The idea is to create a huge sunshade and send it to a far away point between the Earth and the sun to block a small but crucial amount of solar radiation, enough to counter global warming. We could smear the Earth with a sun creme factor 50+Million too.

I was 10 when it came out. I read it a year or two later, pretty much my introduction to sci-fi. I haven't read a lot of sci-fi since, but saw several of the popular movies and tv series (mostly with my kids).

I d o like Sci-Fi and have read quite a bunch of books when I had more spare time... looking forward to do it again when the kids are a bit older and don't need so much time from our side.
I could recommend you a couple of things if you want.

All the costs will be under budget, and we will cap our greenhouse gasses to balance out this mighty new protection! /s
ps - feel free to delete this rather crass post. I would not want to explain it to a youngster. Nor would I want to explain about the L1 lagrange point, how big in diameter this c****m object would need to be, and given that diameter, the difficulty of keeping the object stable at that point without continuous energy inputs.

There are sooooo many things that were not considered als potentially going wrong in that... not to start with needed resources and technolgy to implement it.

There was some work done on the idea that it was the pollution of the '50s, '60s, and '70s that caused "global cooling". Apparently the pollution in the high atmosphere caused the Earth's aldebo to rise, cooling the Earth. So what we need to do is to repeal the Clean Air Act (in the USA) and similar acts elsewhere.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.
