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 …

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 adva…

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 …

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 educati…

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 you…

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 b…

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 b…

ThinLTO was written by people responsible for peak optimization of very large programs at Google. I honestly can’t call it “fast” but it’s a lot faster than GCC LTO. You normally o…

Power limits have the same problem, don't they? Except it's maybe worse because you get the product of the error terms for Icc and Vcc?

I wonder how much of this is due to measurement error of temperature. Core frequency and voltage control are governed by some suspiciously round numbers like Tj(max) == 90C. But wh…

See that’s the kind of information I want to surface in an interview: candidate thinks C++ doesn’t have random-access iteration. No hire.

SunRay were not Solaris-only. In fact virtually all of the ones that sold were used as Windows terminals.
