My favourite thing ever seen in source code was a comment that read “this code is temporary” with developer initials and a date that was at the time about 5 years ago.
Followed by another dated comment from about 3 years later that read “Temporary my ass”
😂
Not sure where you’re getting 250kwh/m2/year from. If it was one contiguous solid panel maybe you could achieve that and then you’d be correct it would be about 560,000 km2. Or roughly the size of France.
But you need to leave space between the panels in a solar farm for them to be at the optimal angle without casting shadows on each other. Real world solar farms have much lower density than that.
The density can vary significantly, our hypothetical solar island could be anywhere from the 6th to the 50th largest country but regardless we’re still talking about something in the area of a trillion individual solar panels.
Assuming money isn’t the limiting factor (which it isn’t in most countries) we don’t have anywhere close to the ability to manufacture and deploy that many panels by 2030 or 2035.
Assuming we maintain exponential growth of both wind and solar (doubtful) we’re still a least two decades away from eliminating fossil fuel electricity generation never mind meeting the 2-3x generation capacity needed to transition transportation and other consumers of fossil fuels over to electricity.
Renewables growth has shattered estimates before, you never know, but the transition is not happening any where near as fast as people seem to think.
You might want to do some basic math on the current rates at which renewable energy and global energy demand is growing.
The world burned 140,000 TWh worth of fossil fuels last year, a new record because global energy demand is still growing faster than total new renewable generation.
Let’s say we built an island of floating PV panels in the ocean large enough to generate that much energy.
It would be the 8th largest country in the world.
No we’re not going to hit 70% by 2035 even assuming it maintains exponential growth, not even close.
No.
MW is the maximum capacity not the average.
A nuclear reactor runs at close to its maximum output pretty much 24/7/365.
A solar farm only operates during the day, and even then it only operates at maximum output in the middle of a clear sunny day.
The overall average output of a nuclear plant is typically around 90% of its capacity.
The overall average output of solar farm is 20-25%.
This massive farm will still only output a bit more electricity than what a single nuclear reactor outputs.
A nuclear power station typically has more than one reactor, so compared to a typical nuclear power station this isn’t even close to the average nuclear plant.
Though it does beat a few of the smallest nuclear plants that only have a single reactor.
Nuclear outputs a fuck-ton of electricity for its size.
Sometimes ChatGPT/copilot’s code predictions are scary good. Sometimes they’re batshit crazy. If you have the experience to be able to tell the difference, it’s a great help.
Stated goals of the UN charter according Wikipedia:
to maintain international peace and security, uphold international law, achieve “higher standards of living” for their citizens, address “economic, social, health, and related problems”, and promote "universal respect for, and observance of, human rights and fundamental freedoms for all without distinction as to race, sex, language, or religion.
Did they even read the charter before having their little temper tantrum?
I question the methodology here. The same site lists Linux desktop share at 2% in my country specifically. It feels like if it was that high you’d see it on people’s laptops more in coffee shops and what not… but I’ve yet to see a single other person using Linux on the desktop.
I know most of that 4% is in India… but still feels like it should be more ubiquitous if the number is that high.
Will you accept wolfram alpha as credible source?

Special care is needed when interpreting the meaning of a solidus in in-line math because of the notational ambiguity in expressions such as a/bc. Whereas in many textbooks, “a/bc” is intended to denote a/(bc), taken literally or evaluated in a symbolic mathematics languages such as the Wolfram Language, it means (a/b)×c. For clarity, parentheses should therefore always be used when delineating compound denominators.
What is your source for the priority of the / operator?
i.e. why do you say 6 / 2 * 3 is unambiguous?
Every source I’ve seen states that multiplication and division are equal priority operations. And one should clarify, either with a fraction bar (preferably) or parentheses if the order would make a difference.
You state that the ambiguity comes from the implicit multiplication and not the use of the obelus.
I.e. That 6 ÷ 2 x 3 is not ambiguous
What is your source for your statement that there is an accepted convention for the priority of the iinline obelus or solidus symbol?
As far as I’m aware, every style guide states that a fraction bar (preferably) or parentheses should be used to resolve the ambiguity when there are additional operators to the right of a solidus, and that an obelus should never be used.
Which therefore would make it the division expressed with an obelus that creates the ambiguity, and not the implicit multiplication.

Total monthly posts exploded after Spez enshitified Reddit, and is still growing steadily month over month.
That suggests that the current decline in monthly active users is primarily because lurkers who only came to lemmy after initially hearing about it on Reddit, went back to lurking Reddit.
The number of users that are contributors is still growing, and that’s what’s important.
After going nuclear against ad blockers, at some point google is going to introduce a new “feature” where YouTube uses AI with your phone’s camera to automatically pause videos when you look away from your phone.
Then they’ll make it so you have to buy a subscription to turn it off during ads.
