Comment Re:Why don't google searches simply return IP (Score 1) 213

If google has the DNS then Why doesn't google return the text-url when they could just return the numerical IP address in the link directly? That way you could skip the DNS step entirely. FOr sites you visit a lot they are probably already cached so a large fraction of uncached links come from google searches so this optimization might matter and it certainly would make google searches seem faster

When dealing with HTTP, you don't only have to work with connecting to the correct IP, you also need to connect to the correct hostname. HTTP uses a Host: header that indicates which host the client wishes to receive from, making it possible to host several different domains on a single IP. Thus, you can't just return an IP adress in the search result, that would be useless.See the Apache vhost documentation for more information about the Host: header and how it is used.

Comment Re:What is to keep the pirates from using this? (Score 2, Interesting) 770

It might take 45min to clear up a small prop - but if you foul a prop of a massive vessel like these you're in for a day's work

Not to mention the fact that a merchant ship's propeller (often) is submerged under the hull, out of reach for any "rope cannons" or whatever you'd call it. Outboards are, of course, a completely different story. I'm a sailor and have seen several people get a rope stuck in their outboard propellers. It's probably the worst thing that can happen to you, 45 minutes is a very conservative estimate especially since TFA mentions specally-made kevlar ropes.
A range of 400m is also mentioned, but if I was a skipper of a merchant ship 400m is far too close. Add the effects of wind, fog and waves range and accuracy diminishes quickly. At 400m all the pirates have to do is to fire an RPG round over the deck to prove their point, then it's game over.

Comment Re:rotate it (Score 2, Insightful) 177

Works in theory, but a rotating spacecraft would in practice be a horrible experience. To achieve enough "artificial gravity" the angular velocity needs to be pretty high (assuming that the diameter of the spacecraft is much smaller than the diameter of the earth), which in turn generates a lot of coriolis forces. These coriolis forces are not very pleasant. Ever been on a thrill ride in an amusement park? Imagine being stuck in such a rotating thing for more than a limited amount of time...

Comment PIO or DMA? (Score 2, Interesting) 168

Sure you can yank up the bandwidth of USB3, but as long as you're stuck with PIO that isn't much of a gain. I would rather have USB3 have a DMA extension for really fast transfers instead of having to have the CPU wake up for every little I/O operation. On a related note, does anybody know any laptop brand that sells computers *with eSata*? That would be awesome.

Comment Old news. (Score 1) 128

This is nothing new. The 1987 U.S. America's Cup challenger Stars and Stripes pioneered the idea of having a specifically structured texture on the outer hull. Source (see page 60).
Later on the internaional yacht racing rules were amended with rule no. 53,

A boat shall not eject or release a substance, such as a polymer, or have specially textured surfaces that could improve the character of the flow of water inside the boundary layer.

.
The Stars and Stripes design was to use microscopic V-grooves alongside the hull, and when optimized for a specific speed throgh the water, actually gave some improvement. If the scientists could get this to work in tough conditions like on cargo ships as well, we could save a lot of energy.

Comment Re:Question about Pi and circles. . . (Score 1) 432

Yes, it is certainly possible to prove that pi is irrational. Wikipedia comes to the rescue.

Basically, a number x is called rational if there exist two integers a and b (b not equal to 0) so that x=a/b. Confusing as it may sound, there are numbers "between" the rational numbers that cannot be expressed as a quotient. The Wikipedia articles are an excellent introduction to the very interesting theory of numbers.

Comment Re:expect a lot more of this (Score 1) 108

The limiting factor is usually the sensor getting warm, that's why you'll only be able to record 12 minutes of video. The digital sensors still have a long way to go before they get really usable. For instance, all DSLR:s that I know of still uses a mechanical focal plane shutter. The best reason not to do any movie recording at all is to reduce dust that gets stuck on the sensor.

Comment Re:Bravo! (Score 2, Interesting) 674

I think that in the next 5 years the PP will focus more on presenting these issues to older people, as well. Singing to the choir will only get you so far..

Very true. The issues that PP attacks don't just concern youngsters, more and more people here in Sweden are raising their voices against the stupid laws that have been introduced.

On another note, my old grandmother told me she had voted for the pirates today. I've never spoken to her about politics before, but apparently she found out about the party on her own and sympathised with their agenda (she's 77!).

The pirate movement has reached critical mass and is now entering the large political arenas. Let's see what rhetoric the MAFIAA and IPFI will use now. We can safely say that less people will be fooled by their lies from this day.

Comment Re:Translation (Score 1) 329

Google fails to automatically translate the page, but not the content. Translation follows:

I don't know any Swedish, but it seems like a pretty good translation. The main thing left untranslated is the word "jävsfrågan" which recurs repeatedly throughout the text.

While I don't know Swedish, I know enough Germanic languages to guess (correctly as it turns out) that "frågan" is 'question'. And "jäv" appears to be 'bias' with 'jävs' the genitive form, thus "jävsfrågan" appears to be 'question of bias'. Similarly, "anklagade" is 'accused', so "jävsanklagade" is 'accused of bias'.

Yes, your guess is correct. (I'm Swedish)

I'm pretty certain I've seen a film where that was the plot. Fucked if I can remember what it was called, and I sure can't be arsed to look it up. Sorry.

From the top of my head I remember seeing this in a Tintin story, though it seemed more of an automatic rifle hidden in a large-format camera.
