The industry also has fairly long product lifecycles (since, once you've put in a zillion card readers and integrated it with all your other building security stuff you don't want to rip it out and upgrade in 2 years).

This is the core issue. When evaluating what should be done you have to consider available technology... and in this case your baseline is 10-20 years ago because old systems don't get replaced very often and for new systems backward compatibility is important, as is minimizing the number of distinct products you have to manage.

perhaps the primary goal is to not be low-hanging fruit

Exactly. The goal is to avoid being the easiest target around.

If bad guys wanted to work hard they'd just get a job. There are contexts in which the value of a target justifies expending a lot of effort, but they're the exception. In every case real security is all about correctly understanding the threat model and then applying adequate mitigation.

Can't say I've ever heard of [...] security by litigation.

Then you weren't around for the DeCSS cases.

I was... and security was not successfully achieved by litigation, nor even by ITAR restrictions. I think I still have my DeCSS t-shirt somewhere, with the code printed on the back. At the time that t-shirt was arguably an illegal munition, which of course is why it existed and why I bought it.

They're still making money from marijuanna sales there. I could have told them they wouldn't make that much money, they were way too optimistic, and set the tax rates too high to properly compete with illegal sources.

Compounding that was a federal campaign against the financing and housing of legal dispensaries - they have a hard time getting the money to get the economy of scale necessary for profit. Leasing commercial property is also almost impossible.

If it still reduces accidents as well as red light running, does it matter if 'more' people run the yellow? The goal of traffic signals is safe intersections and driving, not a 'Simon Says' game.

Note: Link provided not for unbiased site, but because site does have links to reputable studies.

I DID read a biased FAQ by a red light company. Note how they pound the cost of accidents in life and property damage, citing studies. But when it comes to how red light cameras effect the crash rate? 'If red-light and speed safety cameras reduced by an additional 25%...'. Uncited supposition.

Fact is, the 'typical' fatal red-light running is a person going through an 'aged' red, at high speed, while drunk. Not the type to be worried about a camera at that point. Most accidents involving 'fresh' reds are minor, comparable to the rear-end collisions that increase due to the cameras(google should give studies easily).

  I apologize for not linking a study, but I have to head out.

Good idea! They even make fancy ones that can bend to turn corners a bit and use the shape of the rollers to keep the product on them going the right direction and not falling off the conveyor.

A slight slope would be all that you'd need to keep the product moving without any further human assistance.

Depending, the ice truck should already have one available. Heck, worst case have a cart.

Hmm, now I'm curious. A fighter may have a takeoff weight of say 15000kg. Let's say that the "short lean female" saves 40kg over an "average male". With the other reductions - clothing, oxygen, etc - you probably get down to maybe a 60kg savings. That's a 0,4% reduction in system mass. The rocket equation (applicable here too) probably boosts that up to about a 0,5% benefit in many regards. Still not that much

However, if you can shrink the cockpit , then you're looking at a much bigger advantage - possibly 100-200kg extra weight savings and maybe cutting 5-10% off the total aero drag. That could actually be a big deal - relevantly faster accelerations, top speed, range, etc.

There is no "how human societies have been organized". Some societies have had (and even continue to have) near complete segregation of the sexes except for reproductive purposes. Some have had full integration.

And "popular wisdom" is in general stereotype BS. It was "popular wisdom" that said that people of African descent were worthless for anything except manual labor and it's pointless to try to educate a woman, that gays are a social evil that needs to be obliterated, that burning witches is the only way to save the town, and that letting the races mix is tantamount to national suicide.

You seriously think you can make a claim credited to a scientific study, and then when you can't show evidence that such a study claiming what you did was ever conducted, suddenly switch to a "but everyone knows" laden with old gender stereotypes and the standard lame appeal to darwin - and think that will fly?

In almost any sentence where people say "Women (verb)..." or "Men (verb)..." and it's about something psychological (as opposed to, say, something involving reproductive organs or a statistical difference in strength / height or the like), 99% of the time it's equally accurate to simply say "People (verb)..." The popular perception of differences between genders (including the effects of both brain structure and hormones) is often vastly different from the statistical reality. Screw Mars and Venus; men and women are from Earth. Psychologically, we're statistically virtually identical in most measures. And in many cases where there are differences that even manage to meet statistical significance, what differences there are may well be artifacts of culture.

How little are most of these "differences"? This set of graphs puts it into perspective.

Again: Either present your supposed "study" or drop the issue.

Nope. It's identity eminent domain

haha, only they might actually argue along those lines (no shame). They're also appropriating Facebook's computer resources to make these profiles operate - it's no different than seizing property or money on a small scale, and the 5th Amendment has something to say about that (n.b. I'm playing the game that the Constitution is still in effect, rather than used to paper over "trouble").

If the nucleus really had been 50km in diameter (original estimated maximum), and if it had hit Mars, it would've significantly increased Mars' atmosphere with one blow.

Some folks have recommended nabbing some passing asteroids and detonating them in the Martian atmosphere, just to create more atmosphere as they burn up. I still don't know how they deal with the lack of gravity, though.
