I'm no expert but I read that coal-fired electric generation and industry in the Ohio Valley is a major source. This transport of pollutants is apparently codified in the US Clean Air Act. This article seems to discuss the things I was considering years ago: https://ehsdailyadvisor.blr.com/2019/06/epas-denial-of-petit...

I think of the laser as saving us from losing an arm in IBM's variously terrifying chain printers.

That list of cities is a bit whimsical. I don’t often think of Juneau. It doesn’t seem like the kind of city of international prominence, where people might consider moving to advance in their careers. In fact it is not even on Wikipedia’s list of American cities. According to Wikipedia, my university has more undergraduate students than Juneau has citizens.

The air pollution in Pittsburgh isn’t caused by things under the control of the local government or even the state government. It accumulates and blows in from west of there. Only the US federal government can fix it.

I reached the same conclusion but luckily before moving there. Pittsburgh just has bad air. It also has the least sunlight of any American city.

The graph is electric generation only. Electricity accounts for less than 1/3rd of US greenhouse gas emissions.

They’re not steadily falling. As noted in the article, they were up in 2018.

I get the impression from the map of responses that many respondents were taking the piss. Who really thinks Iran is Greenland?

This is the second time in one day that some bozo on HN has assumed that “we” means “Americans”. A peculiar American habit.

Because we’re all idiots and waited too long, we need to cut emissions by 15% annually, not 2%. 2% does not even offset the increase in US emissions in 2018. 2% is a disaster.

"We need labels that strike at the heart of each issue"

That's pretty much the opposite of the "housing first" approach.

Why do Americans [anything]? Because in short they are ignorant.

Americans lack perspective on virtually all topics. They don't read enough, they don't travel enough, their educations are overwhelmingly technical and occupational at the expense of philosophy and ethics, and their domestic brainwashing apparatus has left them collectively unable to think.

Transportation is just like any other topic American's are unqualified to comment upon, like healthcare. They've been indoctrinated by propaganda campaigns to believe and repeat a series of false statements: their cities are too spread out (they aren't); their cities are exceptionally far apart (they aren't); their weather is somehow unprecedented (it isn't); you can't take groceries/children/lumber home on the bike/bus/tram/train (you obviously can).

So the answer to the headline's question is the obvious one, the one with the most hard evidence and the one with the broadest explanatory powers. The reason Americans believe these things is because of ignorance.

Funny that you have this user name, when the article (which you obviously didn't even read) discusses the comparison of Boston and Oslo.

The implementations in the benchmark are all pretty naive. You might get a different outcome with more careful implementations of the functions.

I imagine the downvoting is due to your erroneous projection of the customs of your locale to the entire larger world. Even narrowly considered, your links don’t really support your point of view (eg there are numerous shared pedestrian/bicycle paths in California, children are allowed to cycle on sidewalks in California, etc).

Thank you for sharing the customs of your people and/or jurisdiction.

Guess I'll just stick with the air horn.

The killer application for this technology is a bicycle bell you can use to break the trance of phone-staring pedestrians who are randomly staggering down the pavement.

Yes, and sometimes you want to validate a performance change and you need the release build to run in the benchmark fixture, and then it's irritating that the build takes forever but what can be done? ThinLTO's real benefit is that it uses so much less memory than legacy LTO and can be applied to larger programs (like Chrome).

Everybody should build everything with a reasonable setting of march. Debian Linux still builds everything for K8, a microarchitecture that lacked SSE3, SSE4, AVX, AES, etc. Even building with march=sandybridge seems petty conservative and gives significant speed improvements in many common cases.
