Submission + - Sweden's New Car Carrier Is the World's Largest Wind-Powered Vessel (cnn.com)

An anonymous reader writes: Oceanbird might look like a ship of the future, but it harks back to ancient maritime history — because it's powered by the wind. The transatlantic car carrier is being designed by Wallenius Marine, a Swedish shipbuilder, with support from the Swedish government and several research institutions. With capacity for 7,000 vehicles, the 650 foot-long vessel is a similar size to conventional car carriers, but it will look radically different. The ship's hull is topped by five telescopic "wing sails," each 260 feet tall. Capable of rotating 360 degrees without touching each other, the sails can be retracted to 195 feet in order to clear bridges or withstand rough weather.

The sails, which will be made of steel and composite materials, need to be this size to generate enough propulsive power for the 35,000-ton ship. Although "the general principles of solid wing sails is not new," designing the Oceanbird's sails has been a challenge, says Mikael Razola, a naval architect and research project manager for Oceanbird at Wallenius Marine. That's because these are the tallest ship sails that have ever been constructed. "This ship, at the top of the mast, will be more than 100 meters (328 feet) above the water surface," says Razola. "When you move up into the sky that much, wind direction and velocity change quite a lot."

Umm, no. *(ptr + 20) is different from those above. That would translate to *(char**) (((void*) ptr) + sizeof(char*) * 20). Whilst ptr[0][20] and (*ptr)[20] translate to *(char*) (((void*) (*ptr)) + sizeof(char) * 20).
And (ptr + 20) is even worse since it's completely missing dereferences.

Your printf example is correct though, but not relevant to the current case.

Interestingly this last link refers to CO2's 'low toxicity'.

Well, CO2 isn't really that toxic. You'll die if you breath in pure CO2 anyway though. But that's because you'll suffocate since it is heavier than air and therefore remain in your lungs and prevents any new oxygen-rich air from entering.

It will also fill up closed spaces like basements and you'll basically drown in it.

Yes, actually. At least here in Sweden. At the end of the year your employer, your bank etc report your total income for the year, and some other things that affect tax (like loan interest expenses, savings interest income. Also if you have used some tax deductible services (i.e. home renovation) those companies have to report that as well. Then sometime during spring the tax department sends out a preprinted form to you. If everything is correct you can just sign it and send it back. Otherwise you fill in the changes, sign it and send it back. Or, if you don't feel like beeing a luddite you can use the online service to see and sign the form even before it arrives in the mail.
Then you have until august (I think) to pay your taxes. Except your employer already deducted a standard amount of taxes on your salary and payed it for you, so most likely you will get a tax return instead. Which is payed to you in august as well, except if you used the online service. In that case you receive it in june.

So to sum the process up:
1) Log in to online service during spring.
2) Sign prefilled online form.
3) (No step three)
4) PROFIT (aka tax return around midsummer)
