Comment Re:As usual, more detail needed (Score 1) 114

Generally speaking you should never, ever change your behavior based on the results of a single study -- even a controlled, double-blind study, much less an epidemiological survey. You should wait for a comprehensive literature review paper in a high-impact peer reviewed journal before you consider a result reliable.

That said, correlation is still quite valuable -- to researchers. Science doesn't have the resources to come up with quick, definitive answers on a question like this, involving a complex system that is expensive and ethically tricky to monkey with. So science spends a lot of time doing safer, more affordable stuff like looking for epidemiological correlations, until it can justify spending a lot of rare research dollars on something more probative. And those dollars are about to get a lot rarer too.

Kiribati is going underwater. Does anyone else care? *sigh*

I could rob you and beat you to pulp. Would anyone else care? The answer is that wise people would care, because they'll know if I get away with that I'll be getting away with a lot more.

Same with climate change. Yes, Kiribati may disappear. But the Kiribatians aren't the only people who will pay; in fact most people in the world will end up paying. The way this works is that we all get some up front economic benefit from unregulated carbon emissions and we all pay for the consequences later, but the trick is that the benefits and costs aren't spread uniformly. Some people make a killing on cheap fossil fuel and then can move the bulk of the resulting assets out of the way of climate change. The worst hit are those whose wealth is in land -- the Kiribatians obviously, but also farmers in places which become unsupportably arid.

I don't think it's greed. I think it's wishful thinking.

And it absolutely would be great if there were no downsides to burning all the fossil fuels we can lay our hands on. Most people on this site are too young to remember the smog we had in the 1960s and 1970s; they're imprinted on a time when gas was cheap, air was clean, and anthropogenic climate change was (as far as the general public was concerned) undreamt of. Who wouldn't want that to be true?

They don't need me to tell them it's a bad intersection

They do if the city uses citizen reports as a metric to prioritize allocating budget for improvements to its intersections.

Another thing... are you suggesting that my lack of reporting this makes my analysis of the issue less valid?

No. But in my opinion, one analyzes an issue in order to find a solution.

Or are you simply trying to gently redirect the conversation

Yes. The conversation went in one direction, namely clarification of the problem with this particular approach. Once I realized the problem was an underprovisioned LTYOG, that direction concluded, and I redirected it toward what can be done about the problem.

from pointing out that your counterpoint isn't very good to a conversation about my poor citizenship?

I'm trying to be helpful, suggesting measures that have a chance of getting a problem solved.

How is a motorist stopped at such an unresponsive signal expected to recover the use of his or her vehicle?

Technically, you don't.

So in other words, all motorists using British roads are subject to having their vehicles seized at any time for any reason through deployment of a red traffic signal. Or what am I missing?

We turned around

That would work in theory except for a one-way street or an intersection with a no U-turn sign.

rang the police

Using what? Are all motorists using British roads required to keep a valid subscription to mobile phone service?

In addition, I tried ringing city services in my own (U.S.) city when facing a red light that would not respond to my bicycle stopped making a chord of the induction loop's sensor, and representatives blew off the report repeatedly. Or is government attitude toward reports of stuck traffic signals a difference between Britain and the U.S.?

[In Britain,] If you cross the line on red, you've broke the law, whether it was red for 0.1 seconds or 10 years (note: you can't even cross it if an emergency vehicle appears behind and you need to cross it to let them pass... it's AGAINST THE LAW to cross the line once the light is red).

Basically, their lights flash green 5 times before they go to yellow, giving you ample time to know that the green period ends.

A pre-yellow warning phase also causes motorists to increase speed inappropriately, which is why the United States has not adopted a pre-yellow vehicular phase.

Comment Re:40.000 deaths (Score 1) 231

Often blatant red light violations come from intersections with no left turn arrow. Frustrated drivers wait an entire light cycle (or four), and then finally just go when the opposite lane clears as the light turns red.

If you're referring to intersections that show the left* lane a green disc instead of a green arrow, the proper maneuver is a "LEFT TURN YIELD ON GREEN" as described in the driver's manual. First enter the intersection while the signal is green. Then by the time it turns red, you're already legally in the intersection and have the right and duty to clear it once oncoming traffic to your left ceases.

Or are you referring to left turn lanes whose signal doesn't turn green because its buried induction loop is failing to pick up your vehicle?

* Assuming USA and other countries that drive on the right.

Comment Fullscreen to be restricted to secure cont (Score 1) 231

I think that has something to do with browser publishers deprecating the Fullscreen API on cleartext HTTP sites to make it harder for a man in the middle to impersonate your device's operating system. (Search keyword "secure contexts".). Do the pages an where embedded YouTube video falls to go full screen use HTTPS or cleartext HTTP?

please keep in mind that a lot of us watch youtube on our "smart-tv" devices, Nintendos, Xbox's Youtube app etc.

Or use a HOSTS file ad blocker.

Editing the hosts file requires root access. Root access is difficult to come by other than on personal computers. You'd need to run your own DNS to cover devices where only the manufacturer, not the owner, has root.
