So if you imagine a connected line of 233 suns across the sky, spanning 57.3 degrees, the actual length of that line would be the same as the distance from your eyes to the sun.

John Conway is actually one of the authors of the book discussed in the article.

The original article is a bit better:

Apple isn't actually prevented from selling either new or refurbished iPhones in India. What it appears that they cannot do, though, is open any Apple Stores there, because they don't (or can't) comply with a rule that "at least 30 per cent of the value of procurement of manufactured/processed products shall be sourced from Indian small industries" (from a similar story about Walmart: http://www.thehindu.com/business/Industry/30-local-sourcing-...)

It looks like what they wanted to do was to manufacture the original phones in China, as always, but do the refurbishment in India, and thereby call the refurbished phones "locally sourced". If they could do that, then they could run their own stores in the country, assuming that the refurb phones made up 30% of their product.

The Indian government rejected that idea, so I presume that Apple will need to continue selling through third-party retail stores, or come up with another way to comply with the rule.

Apparently they have that covered, too: http://motherboard.vice.com/en_ca/read/canada-changed-its-el...

It can't be officially signed until after the election, but they can still negotiate. And all three parties, according to the article, are in support of the agreement.

Big Hero 6 isn't original, if that's what you're saying there -- it's drawn from the same Marvel universe as Captain America and Guardians of the Galaxy.

Heavily adapted for a different audience, certainly, but still not an original story.

From reading http://en.wikipedia.org/wiki/Helium-3#Fusion_reactions, the 2p are two protons, and not positrons, as valarauca1 is saying.

So, 4 protons and 2 neutrons go in, 4 protons and 2 neutrons come out.

But charge still needs to be conserved -- I presume that the spare electrons just aren't shown in the reaction; if they were bound to the protons, then we'd see 2H rather than 2p.

And if your problem requires only one of each, and needs them for the same amount of time, then your optimization would be the correct one.

Now scale this to a situation where solving the problem requires ten thousand machines for each developer working on code, and where each minute of time spent writing code translates into two days of machine time running that code, and the numbers start to look different.

This all looks like a lot more drama than it really is. There's a lot of reasonable discussion going on between the two parties now.

It's more likely that it's because they are two separate physical actions (returning the head to the left, and advancing the paper one line). They could be used independently: You could print a line in bold, for instance, by issuing a CR without an LF and then printing the same line again.

A carriage-return operation takes much longer than a single character, or even two or three. It doesn't make sense to issue two characters just to take up time. The printers always had to have some internal buffer memory (and handshaking over the communication lines to say when the buffer is full) in order not to lose any characters.
