I have been to Cuba earlier this year. We travelled around by car from the west to roughly the middle of the island. We slept in private casa particulars and talked to the local people. While it is obviously true that the villages are somewhat impoverished, I can tell you that Cuba seemed so much better developed than other latin american countries, like Peru. In Cuba, our hosts all had internet access. It was slow (dialup), but people were using AirBnB and the like to advertise their casas. They would use Facebook, Google and Gmail and some even had iPhones and iCloud.
Even in the small villages, people's homes were sort of neat, even if they were old and a bit run down. Everywhere it was obvious that people did take care. And yes, there were obvious shortcomings of goods like meat, toilet paper. A bottle of coca cola was insanely expensive.
In Peru on the other hand there was an abundance of internet access -- internet cafes and free WiFi even in the most remote village. Coca Cola and Inka Cola everywhere. However, the whole country was much more littered, homes were absolutely shabby outside of the neat centre of Lima and the tourist spots. The poverty of the poorest was so unbelievable.
I certainly hope that Cuba evolves into something better, that the gap between poor and rich doesn't get as bad as that in Peru. And of course I hope that Peru also gets better... Cuba definitely has got a chance to reform and evolve now. I hope that the Cuban people are up to it!

+ - x86 Computation Without Executing Any Instructions->

Submitted by jones_supa
jones_supa (887896) writes "Trust Analysis, i.e. determining that a system will not execute some class of computations, typically assumes that all computation is captured by an instruction trace. A team at Dartmouth College shows that powerful computation on x86 processors is possible without executing any CPU instructions. They demonstrate a Turing-complete execution environment driven solely by the IA32 architecture’s interrupt handling and memory translation tables, in which the processor is trapped in a series of page faults and double faults, without ever successfully dispatching any instructions. The 'hard-wired' logic of handling these faults is used to perform arithmetic and logic primitives, as well as memory reads and writes. This mechanism can also perform branches and loops if the memory is set up and mapped just right. The lessons of this execution model are discussed for future trustworthy architectures."

Look at it from the NSA/FBI's point of view: they already have backdoor access to your phone's data, so the fingerprint scanner isn't about keeping Them out, but about securing biometric data from users voluntarily. If They tried to fingerprint or retina-scan a whole nation Themselves (like our troops do to occupied Afganistan and before in Iraq) there would be resistance; we only got away with it in Afghanistan and Iraq because we were an armed, occupying force. At home, they'll start integrating biometric scanners into cheap, gaudy (GOLD!) baubles so the Sheeple fingerprint themselves instead.

Your government already has my fingerprints. Every time I travel to the US, I have to leave my fingerprint at the border controls in the airport. Several years back, it was just a thumb print. But last time I went, it was all ten fingerprints.

I wonder if humans would evolve further, maybe producing their own beta carotene or Vitamin A? I do not condone the suffering of millions of people, but I wonder if giving our bodies everything in plenty is good in the long run (like generations).

Also, can't this deficiency be solved with existing crops and/or vegetables? The rice looks nice, though...

Comment: GNUStep is a great project (Score 2) 131

I like this campaign. Objective C is continually in the Top 5 of the most widely used languages (http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html). It is a very nice, simple object oriented C dialect. It is used on OS X and iOS, the latter of which is installed on hundreds of millions of devices (http://www.engadget.com/2013/01/23/apple-over-500-million-ios-devices-sold/). Both operating systems heavily utilize Cocoa as their framework

Having better or even any Cocoa support on Linux would help to get developers to target both world. Linux on the one side, and iOS/OS X on the other side. I think this is well worth for all Linux users to chip in some money (even if it's only $1).

This, this, a thousand times this! "The Late Philip J. Fry" is my favorite Futurama episode. So witty and full of good jokes and quotable lines. ("Just slow it down, I'll shoot Hitler out the window.")

But I must concur, the quality of the episodes varies in the last two seasons. I hope there'll be new, excitong shows around the corner.

I go to work by bus, but I still have to work ~1km to and from the bus. Also you could take a bicycle to work. Many workplaces offer showers for bike commuters (ours does). Also I have a dog and have to walk her 3x a day, rain or shine. Thus I get to about 6km of walking each day. Helps a lot.

Please stop. You're suggesting that the brains from one country are somehow different from that of another country. If we change 'country' out for 'race', it should be painfully obvious what the problem here is.

Maybe the brains actually are different from country to country, depending on cultural and environmental influences. What you shouldn't suggest is that either brain would be better than another. Difference doesn't mean that actually something has to be better, just that it works differently, while maybe achieving the same goal.
