...unless you use condoms?

Condoms help. In some cases, such as AIDS, they help a lot. In other cases, like syphilis or HPV, they are far from foolproof, because some STDs do not require contact with infected semen to spread. They still help some, but if you're relying on condoms as your one line of defense while having lots of partners, you're in for a nasty surprise.

sex addicts with lots of partners, etc?

I never got that, in what way is having lots of sex detrimental to the health or well being of a person?

Nothing really unhealthy about having lots of sex. Having lots of different sex *partners*, on the other hand, will make it rather difficult to avoid STDs.

Why not just go the whole hog and eliminate that nasty pay all together? That way they company can be super competitive.

Why do you think they invented unpaid internships?

And now, instead of three competing consoles, we have four.

Without a market, you have no place to sell your stuff.

I'm not looking for a place to sell my stuff. I want to keep my stuff. I don't sell my games, because I enjoy having my rather large collection of them.

Seriously, you don't go out side and think that it feels like it's 19 C, or 85 F

Well, yes, I do. I go outside and shiver, and say "Feels like it's 50" and go back in and get a jacket. I go outside and sweat and say, "Feels like it's 90". I don't do it in Celsius because I don't have any feeling for those numbers; I have to convert into Fahrenheit to understand how hot or cold it is.

but what is one quarter of 236 ml?

59 ml. One quarter of 240 ml is 60 ml, one quarter of four less than 240 ml is one less than 60 ml.

Four teaspoons in a tablespoon.

All my cookbooks say that there's three teaspoons in a tablespoon.

I have seen some "half liter" bottles sold lately.

Six packs of half liters are pretty common in grocery stores around here (I live in the Washington DC area), and you'll generally see 1 liter sodas at gas stations. Just yesterday, I saw 1.5 liter bottles for the first time, at a Target (they also had 2 liters, which is what I bought).

But it might make it clear that it will fail much earlier and then at a lower cost.

But apparently it didn't succeed in that, either. They're discovering massive failure only after three years and billions of pounds.

stated the metric system was "the Preferred system of weights and measures for United States trade and commerce".

Which has absolutely no practical meaning as far as I can determine, unless you can cite some actual concrete consequences of this declaration.

Also said the federal government has a responsibility to assist industry and especially small business, as it voluntarily converts to the metric system

Which, once again, means what? Are there grants? Is the US offering any kind of money to anybody to help fund their conversion to metric?

that use of the word "sandwich" is an Americanism too far.

Ah yes, the Earl of Sandwich was truly one of the great Americans, wasn't he?

if a car has double the efficiency then the L/Km gets doubled. not the same is valid for mpg

If a car has double the efficiency, then the l/Km gets *halved*. Maybe we'd better just stick with mpg.

A few hundred dollars will get you a quadcopter that flies for ten minutes, flies at about half the speed of this, and won't carry anything like its payload, and you'll have to supply any payload yourself.

No, no, no. The pound is a unit of mass.

Try again. The pound is a unit of *weight* (or force, since weight is a type of force).
