Comments on this article are quite surprising.
Basically they all complain that the article is too difficult to understand. Then they say they went to the french Wikipedia and still they did not understand.
Since I am the main author of the french Wikipedia article, I don't think this article is difficult to understand. Rather, I suspect that people who read "lemonde.fr" are just not very smart.

Hum... interesting. That's the second article about bitcoin on lemonde.fr, in a few weeks. |

http://www.reactionengines.co.uk/news_updates.html« Reaction Engines Ltd. can announce today the biggest breakthrough in aerospace propulsion technology since the invention of the jet engine. Critical tests have been successfully completed on the key technology for SABRE, an engine which will enable aircraft to reach the opposite side of the world in under 4 hours, or to fly directly into orbit and return in a single stage, taking off and landing on a runway. » For those who don't know what Skylon is, just watch this: http://www.youtube.com/watch?v=daBKojdOAgs

Really? The federal reserve obfuscated so well for 100 years that nobody understands their scheme ... yet everyone still uses it.
It's easy for people to accept Fed's notes because nobody really gives them much of a choice. For someone to start to accept bitcoin on the other hand, (s)he must decide to do so. That's a totally different mental process. |

Bon il n'y avait personne d'actif sur #bitcoin-fr, par contre sur #bitcoin on a bien déconné. Le moment fatidique était un grand moment de délire total.

Mars has water. Not a lot, but it may be enough. And if you use some solar panels to pump electricity through that H2O, you'll have some H fuel and O to breathe. But yes, it's not as nice as landing on a tropical island. However, tropical islands don't have drinkable water (unless you manage to find a spring), and don't really have food, unless you feel like chewing on vines and bark. So, although it looked prettier, back then it was rather inhospitable as well.
It very much depend on the size of tropical islands. Indeed lots of them are too small to provide fresh water for any human. But I think (though I'm not sure), that where Colomb first landed, there was water, coconuts, vahine and everything. There's lots of water in sahara also, if you don't mind digging deep enough. For some reason it doesn't help making the place less hostile, though. I wonder why it should be different on mars. |

Bon, à défaut de se voir IRL (je ne peux pas non plus de toute façon, comme je disais je vis en Picardie dorénavant), on peut se donner RDV sur IRC
#bitcoin, #bitcoinfr, #bitcoin-dev et cie sur irc.freenode.org

« That was true of the English colonies [in the Americas]; it took a significant expense to get things started. But once there are regular Mars flights, you can get the cost down to half a million dollars for someone to move to Mars. Then I think there are enough people who would buy that to have it be a reasonable business case. » If Elon Musk seriously considers that people should pay taxes in order to finance the dream of a few SF-fans to settle on a giant rock millions of miles away from any drop of liquid water or liter of breathable air, then I'm afraid that to me he is not sympathetic anymore. At all. Comparing Mars to America is just ludicrous. America was not a desert. There was air to breathe, water to drink and so on. Hell, there were even some good-looking, bare breasted native women welcoming sailors with flowers and often offering their body on the beach. And I'm not even joking. I mean come on, the first land where Colomb arrived in America was the Bahamas:  And as a comparaison, this is where Elon Musk dreams of settling down:  Those people are completely delusional. Does Elon Musk love large, arid deserts and wastelands?? We have some of those on Earth, no need to go to Mars: Antarctica:  Sahara:  Pacific ocean (well ok that's not technically a desert but it's just as if. Go try to live there all your lifetime if you don't believe me):  I'm pretty sure those places are paradizes when compared to Mars. |

Getting rid of cash has long been on the agenda of credit card providers, which trade on the fact that they can provide transaction data to the retailers they service. But now a new wave of virtual ways to pay means that consumers could soon be using new currencies Bitcoin and Ven to pay for goods too. Meanwhile, the UK’s three largest mobile networks got together earlier this month to work with retailers on consistent technology that will allow people to pay via a mobile ‘wallet’. WTF is VEN? is quite a famous alternative currency. I'm suprised you don't know the name, at least. |

A lire dans Revue Banque: Bitcoin (Paytunia) au salon "Cartes" grâce à Paymium. « Et si BitCoin permettait de généraliser le porte-monnaie électronique ? C’est le pari ambitieux de Paymium et d’Aqoba, avec leur porte-monnaie Paytunia. Celui-ci n’utilise la monnaie virtuelle principalement que comme un protocole, pour véhiculer des transactions traditionnelles interopérables. » Bigre, si vous parvenez à réaliser l'interopérabilité et ainsi faire en sorte que des commerçants acceptent bitcoin sans même le savoir, ce serait un vrai coup de maître. On pourrait pas rêver beaucoup mieux comme cheval de Troie. A moins bien sûr que vous fassiez la même chose avec une carte bancaire, car là ce serait le gros lot. |

EDIT : et ... je parierais qu'a peine le 210 000 ieme block trouve, beaucoup vont tout shutdown, laissant "ceux qui restent" dans .. le caca pour qq temps  Le truc c'est que y'en a sûrement qui se disent exactement la même chose et qui du coup pensent que ça vaudra le coup de continuer puisqu'il y aura moins de concurrence. Ceci dit c'est vrai que je suis curieux de voir combien de temps on va mettre pour passer de 210 000 à 210 001. |

Works for me: Safeguards built into the bitcoin software are about to be triggered as the number of bitcoins in circulation hits a key milestone.
This means bitcoin "miners" will have to work twice as hard to be rewarded with the same number of coins.
The change comes as competition to create the coins gets more intense with the release of custom mining chips.
Since the creation of the bitcoin network in early 2009, bitcoins have grown to become a very widely used digital currency. An increasing number of online shops and businesses accept bitcoins as payments and currently each bitcoin is worth about £8.
As a digital currency, bitcoins are not issued by a central bank or national mint. Instead they are created by the system's network when a specific amount of computer work, known as a "block" has been completed. Fifty bitcoins are released when that block is done and the work, which involves solving a hard mathematical problem, is completed.
The protocol that defines this block-to-coin ratio reduces the reward given for finding each block every time 210,000 blocks have been found. According to statistics gathered about the bitcoin network, the 210,000 figure looks set to be passed on 28 November. Then, instead of getting 50 bitcoins per block, miners will get only 25.
"The main reason to do this is to control inflation," said Vitalik Buterin, a journalist at Bitcoin Magazine. Controlling the rate at which coins were created, he said, meant there would never be a surge or shortfall in the number of bitcoins in circulation, either one of which could rapidly change the value of each coin.
It addition, he said, it was a hedge against technological innovation. In the early days of bitcoins, many people used desktop computers to do the hard sums. Then they started to use banks of graphics cards that could do the maths very quickly to speed up the rate at which blocks of work were completed.
Mr Buterin said some miners were now using even more specialised hardware to do the mathematical work and firms were starting to produce custom-made chips that stepped up the pace of work even more.
However, he said, the creators of bitcoins had foreseen these changes and built in controls to keep the numbers of blocks completed relatively constant.
"The protocol always calibrates difficulty to make up for increased mining power," he told the BBC, "so the speed at which people are finding blocks isn't going to go up by much no matter what." |

Has anyone written a test-suite for key generation-validation?
I mean, a text/json/whatever file where you'd have a couple of address/private key pairs?
And in all possible formats (test network, compressed/uncompressed and so on...).
That would be useful.

At least I agree with this: « He added that it would be a fun adventure to watch, even if you aren't planning on going yourself. » |

Another in the stream of articles at Forbes from Jon Matonis - with a mention for Stephen Gornick Honestly I'm not sure we should worry that much about this kind of "concurrence". This is all about payments system, and bitcoin is not just about that. Bitcoin is also a currency and it could make use of any payment system. |
