Thanks Phi. Just in case any republicans think the video is absurdly far-fetched. https://www.telegraph.co.uk/news/2016/04/14/ted-cruzs-doomed-war-on-sex-toys-and-masturbation/ And that's from the Telegraph which is definitely Right-leaning.

Is there a version I can see without signing up for Twitter?

No Except, I guess, saying "50%" can only be wrong by +/- 50%

We still do sometimes; it's very effective.

I should have mentioned x-rays too. The carcinogenicity (and other risks) of metronidazole are still under investigation- as are those with any other drugs in medical use. https://yellowcard.mhra.gov.uk/

Very easy. A can of compressed hydrogen with a catalyst would be a better weapon than a water supply.

Fat cows bend in angles. The one I learned for the lanthanides would no longer be considered acceptable in polite conversation. Incidentally, "tetrel" is a new one for me. When was that coined? That means we have the noble gases, the alkali metals, the halogens, the alkaline earths, the chalcogens, the pnictogens , the tetrels and "the boron group" The trivalent ones need better PR.

English as a second language? There is no such thing as "American English". There is English; and there are mistakes. I suspect that a large part of the actual answer to the original question is a fall in the expenditure on education. Yes they do. It means "change" not "improve"

Hypochlorite bleach definitely expires. Also, are you aware of this sort of thing? https://www.rd.com/list/beauty-products-packaging-symbols/

What's special about cancer? Plenty of drugs have a variety of ways of killing you. https://bnf.nice.org.uk/drugs/metronidazole/#side-effects And you need to balance the risk of side effects with the risks of not taking the medication.

Alcohol, sunlight, silica and the fumes from diesel engines are known human carcinogens. Do you suggest that we ban them? Or do you think we should consider the benefits as well?

It's a lot easier to ask their next of kin...

No, it's not. Submarines get squashed to a measurable degree- some would say an alarming extent- even when they are working properly. I suspect he did it because he enjoyed it. It will if it leaks at all. Is there any point? Has anyone said the victims are not the "right" people? DNA will confirm the identities of any bits of body that they find. I guess that's useful in terms of labeling a coffin but I imagine the victims will be considered "lost at sea". Anyway, I predict further empty speculation.

I see another problem. Why poison woodlice for fun?

About 12 seconds into the video, they guy explains that he says you should keep your cards in sight- which is sensible advice. But it has nothing to do with RFID, has it? If someone has your card, it's no longer in the "protective" wallet. Why did you post that video in this thread?

Nor do you. Which means that, if Sensei isn't smart, nor are you. Past evidence suggests that he's smarter than you are. And, in any event, he's right about this.

Good question. How do you intend to maintain an air supply and a route back to the surface without it? Or did you not understand that it was implicit in the requirements I specified? They already started. https://en.wikipedia.org/wiki/List_of_spaceflight-related_accidents_and_incidents So he's just stating the obvious. Just a thought; If A kills B and is subsequently jailed for life for murder, is that a bad outcome? Actually, you sometimes can- as long as you make it 10 times thicker than it needs to be. For a one-off design, overdoing the glue makes more economic sense than building a clean-room etc. ... just as long as you get the sums correct. People seem to overlook teh fact that this sub dived successfully before. The problem wasn't raw strength, but fatigue resistance. To a very good approximation, nothing ever fails in straight compression. Failure of stability.... not very rare.

The bits that haven't already been tested by a million game players? It's a bit beside the point. The game-boy didn't include an "implode" function. In theory the only things that are "critical" are Maintaining air and getting back to the surface. They had at least one "get back to the surface" mechanism that was independent of that controller and the controller had nothing to do with the air supply.

At 20 bucks, and well under a kilo in weight, why not just take a spare?

How many other systems were as well tested as a game controller?

Some people are citing this as an argument against diversity. Those are the people that don't realise that "everyone is young" is no more diverse than "everyone is old". They aren't helping. Interestingly, they also searched the surface of the sea quite intensively in spite of the fact that ... that's not where submarines "should" be.

How come nobody but you has noticed?

Thank you for your anecdote. Sorry to hear that the company is struggling.

Because it is impossible to give a meaningful answer to the OP's question. Because it is potentially helpful to you if we point out that your reply, while well intended, was wrong.

You could sell that. But... how would you advertise it?
