No, 0.999... IS exactly equal to 1.

Which is why floor(0.999...) should be exactly equal to floor(1), ie. 1

Except that my Touch needs to be recharged maybe once a week, depending on exactly how much I use it for gaming on the subway. My ordinary cell phone also lasts about a week on a charge. Yet if I were to combine both, I'd end up needing to recharge it every day. And I'd better have my charger around 'cause it might not last through the entire day.

Maybe it's just the fact that English isn't my native tongue, but... Is this 5 year thing a requirement for the project? Or is it just that Boeing estimates such a plane could conceivably fly for 5 years?

Because I just can't imagine any sort of scenario where something like this absolutely has to stay in the air for 5 straight years and could not be replaced by 2 or 3 of these things doing one-year rotations.

Nonono, all you reall need is to create a black hole in the right spot so you can use its gravity to bend your light beam in such a way that it hits the object you'll be 'pulling' from behind and hey presto, you're pushing!

How about the other way round? Define one year as 365 days. Sure, in (365/2)*4 = 730 years we'll have winters in august in the northern hemisphere, but that's not gonna matter to any computer...

Except that we're talking about food allergies here (yes, celiac's isn't an allergy, but the discussion drifted away from that).

I don't think you can deny that the typical diet of the modern western world has become very different from what it was 100 years ago. Better transportation has allowed us access to more and more 'foreign' foods and keeps making them cheaper and thus available to more families.

By your logic, the fact that people have become exposed to more and more different food allergens should mean food allergies should be declining. Which I doubt they are...

Do it with actual numbers and not percentages, because you're getting tripped up by the fact that your total population changes.

Take 1000 families, with two children. Assuming a perfect distribution, every possible combination of boy/girl for both children results is represented 250 times. Note that the actual order of the children is largely irrelevant, but if you ignore order you still have 250 families with two boys, 250 with two girls and 500 with one of each.

Now you take the next step. You reveal that at least one child must be a boy. This means you eliminate 250 families from your population, namely those with 2 girls. You're left with a population of 750, 500 of which have a girl as well and 250 who have another boy.

Now, pick one family at random from those 750. The odds of getting one with two boys is 250/750 or 1/3.

Yes, 1/4 of (all families with 2 children) has 2 boys, but 1/3 of (all families with 2 children AND at least one boy) has two boys.

I fail to see how you could ever achieve this without also proving your identity. Let's say you walk into a high-security area. You produce all the documents needed to prove that Jim Bobbins has the right to be there. Should you be allowed in? No, because you've given no proof at all that you are, in fact, Jim Bobbins.

As long as it's not a flashvertisement...

As far as WoW is concerned, I'd say that movement would be tricky. There's click-to-move so that should work, but it's a bit clunky. Chatting too. But combat, just clicking buttons... That'd work better than a keyboard.

I don't really mind computers.

I do hate printers, though. All those stupid moving parts, paper that needs to get in and then get out, the heat, the toner... I swear it's all just waiting to fail!

Animals aren't that complicated, really. If they're not hungry and do not feel threatened, they have no reason to attack humans, no matter what size they are.

Nah, your last three letters are correctly capitalized.

Yeah, but what happens when your engine breaks?

You take it to the garage, who tells you they'll need to order a new one. Probably takes weeks (I have no first-hand experience but I doubt I'm far off).

Now imagine that your Honda engine was 100% compatible with any Ford chassis and any Renault chassis etc. Now, if you break your engine and go to the garage, there's a pretty good chance he will have a compatible engine in stock, because now having such a stock makes sense. It doesn't when there's a few hundred different engine models you need to stock.

And you get your car back the next day...

You get a phone, it runs Android, no problem. And, just like your car, as long as you don't want to change anything or add anything, it won't become a problem.
