The problem isn't just reducing the emissions produced by people who already have cars (though that would of course help); it's limiting the future emissions of the huge numbers of people who don't yet have cars, but want the

Corrected headline: "How safe would humans say this street looks?" Not the same question at all. While the research into computer vision and machine learning is interesting, as a human I'd like to know when my intuition about

I liked "Midwest Dental Arts", in the group described as "The company's acronym cut in two colors by an arc (usually Trajan font)". All the other logos in the group have a downwards-concave arc; the dental logo is c

You say "So much of the code out there is "totaled": it would cost more to fix or maintain it than to rewrite it from scratch." If that's the case, why does such code still exist? If it's still running, then in

How about a company that figures out how to provide _very_ affordable high-quality health care to large numbers of people, so they aren't dependent on an employer for their healthcare? That would allow many more people to become free-l

Standard rules of ethics for experiments on human subjects say that (with a few exceptions) subjects should always be informed about the study. If that changes the subjects' behavior such that the study is no longer valid, it's th

There are two separate questions that you're confusing. You seem interested in "is the use of SWAT systematically _more_ biased against minorities than law enforcement in general." The report seems to be addressing "is t

Isn't the ultimate socially-optimal answer for the "guess 2/3rds of the average" game be to convince everyone to answer 0? Because 2/3rds of 0 is 0, so everyone wins.

I didn't say they don't have the right to choose (though there's a discussion to be had about how informed their consent really is), I just said that their choice horrifies me. Coincidentally, I've worked with a former P

I know a few people who do neuropsychological testing (testing IQ, various kinds of memory, spatial reasoning, attention, and so on). Some college athletes are now getting "before" tests, as a baseline to evaluate the severity of

You say C++ has "been used to build the most horrible messy codebases in existence". There are two kinds of programming languages: those that have been used to create horrible messy codebases, and those that haven't been wide

Are you really trying to claim that there are many more new languages than 150 years ago? Or are you saying that there are many more literate people trying to learn a new language than 150 years ago? The first claim is clearly absurd; only

Yes, thanks! I was originally searching for "c++ pv", which led to lots of c++ examples implementing "present value" calculators, or snippets of code using "pv" as a variable name. I later tried "pv tarbal

If you scroll down to the bottom, there's a changelog describing some changes applied during 2003-2011, and then "Copyright 1999-2014", which might give a few clues about how old the document is.
