Sandford Fleming (the guy who invented time zones) actually made it easier.
Before timezones, every town had their own clock that defined the time for their town and was loosely set such that “noon is when the sun is at its highest point in the sky.” Which couldn’t be measured all that accurately.
If it wasn’t for Fleming, we’d be dealing with every city or town having a separate time zone.
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.
Yes you’re correct. I will qualify my previous statement as hydrogen powered road vehicles don’t make sense for now.
The problem at the moment is that electricity generation is not carbon free and in most countries not even close.
Unfortunately the transition to a carbon free electric grid is being significantly retarded by policymakers that are, as you say, myopic. As a result it will be at least two more decades before hydrogen makes sense.
The carbon footprint of lithium battery manufacturing, is small compared to the carbon footprint of electricity generation. Until that changes significantly lithium batteries will continue to be a better choice than hydrogen fuel cell.
Hydrogen may make sense in a future where we’ve eliminated all fossil fuel electricity generation and there’s an abundance of carbon free electricity that can be used to create green hydrogen as a form of energy storage. Though by the time that point comes, we may have developed battery technology or some other energy storage technology that doesn’t carry the same carbon footprint that lithium ion does today.
Hydrogen doesn’t make sense and never did as a strategy to reduce greenhouse gas emissions in vehicles.
Most hydrogen is made from fossil fuels, and has a lot of emissions during manufacturing. But even green hydrogen, which is made by using carbon free generated electricity to split water into hydrogen and oxygen doesn’t make sense.
If you’ve build new renewable power it’s more efficient to use it to charge batteries than to use it to generate hydrogen.
There might be a case for compressed hydrogen, In vehicles where batteries are too heavy like aircraft.
But for road vehicles, batteries are more effective at reducing emission.
If you’re building any new renewable power, you’ll reduce more emissions by using it to displace coal power, the to generate green hydrogen.
Some day when we’ve eliminated fossil fuel based electricity generation, Green hydrogen might start to make sense. But anybody trying to do it right now is not being as helpful as they could be.
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.
If a website using home realm discovery adds anything more than one extra press of the enter key or mouse click of an ‘ok’ button, get a better password manager.
If you’re annoyed by that one extra click that’s fair. Click counts matter.
It’s called home realm discovery. It’s common in business apps though it’s usually used with email & password logins not username & password logins.
It’s done that way to support federated logins. Larger companies will often used a single sign on solution like Okta or Azure AD. Once the user’s email address is entered it checks the domain against a list of sign on providers for each domain and redirects the user to their company’s federated login if it finds it there instead of prompting for a password.
This has several benefits:
The user doesn’t have mutiple passwords to remember for different apps. Which is know to result in users either reusing passwords or writing down passwords somewhere.
When an employee quits or is terminated the company only needs to disable their account in their company directory and not go into potential dozens of separate web apps to disable accounts.
The software vendor never receives the password, if the vendor’s system is compromised they don’t even have password hashes to leak. (Let alone plain text or reversibly encrypted passwords)
Websites that work that way are (usually) doing it right. If that doesn’t work with your password manager, you should (probably) blame the password manager not the website.
Reddit never expected the new api pricing to be a fountain or money. This was never about LLMs or the lack of ad revenue.
If it was just about LLMs they could have made one price for api users that were primarily harvesting data and a different price for api users that contributed significant content or moderation. Which would make good business sense to do so as content contributors are what bring the eyeballs (and therefore the value) to the platform.
It wasn’t about ad revenue either, by all estimates the revenue from a third-party app user would have been many times more than the opportunity cost from the ad revenue they were missing out on from 3rd party app users. If they wanted to profit from the api pricing, they only needed to give the community more time to transition business models. They didn’t even need to give everyone more time, just a dozen or so major third party apps.
This was always about killing off the third party apps. The ones they let survive had low user counts to begin with and went even lower.
I don’t know their real motivations here but so far there’s only two possibilities that i can think of.
A) Reddit’s leadership and board of directors are beyond incompetent
B) They collect significantly more data from the first party app than they were able to from the third party apps, and they’re selling that data for a significant sum of money beyond just their own ad ecosystem.
Will you accept wolfram alpha as credible source?
https://mathworld.wolfram.com/Solidus.html
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.
(Rest of the post is great)
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.
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.
