Antennas using 802.11n have been able to achieve transmission distances over 300 km unamplified.
Well that is more interesting! If something like this could be used to link cities. I'm guessing that terrain matters though and this "300km" was line of sight? feet, not kilometers. 304 km http://www.v3.co.uk/v3-uk/news/1984314/wi-fi-world-record-set-304kmhttp://en.wikipedia.org/wiki/Long-range_Wi-FiYes, it has to be line of site. link first established on 2007-06-16 it appears to be permanent from Monte Amiata (Tuscany) to Monte Limbara (Sardinia) frequency: 5765 MHz IEEE 802.11a (Wi-Fi), bandwidth 5 MHz Radio: Ubiquiti Networks XR5 Wireless routers: MikroTik RouterBOARD with RouterOS, NStreme optimization enabled Length: 304 km (189 mi). Antenna is 120 cm with handmade waveguide. 35 dBi estimated I imagine with a VLA you could get thousands or even millions of miles. |

7% is not outrageous for the convenience, but I doubt the entire story. There's a lot of weird things going on in Ukraine these days.

is it YYYY-MM-DD OR YYYY-DD-MM What happened on that day? you resigned? YYYY-MM-DD is customary in USA. It presumes to answer the thread title question. |

This is a well planned product line that provides the necessary devices for consumer adoption of Bitcoin.

I put in my two-week notice around then and lasted 4 more days. |

Some folks believe in open source and some don't. We're all stockholders in the cryptocurrencies we invest in. I think their will be a time soon when big corporations will see the value in donating development time to open source projects that pay social dividends, such as Bitcoin.

In that case, median net wealth for US adults is only ~$38,000 USD. Which I actually find surprisingly high. That median is composed of the under 40 crowd who largely have negative net worth, and the over 50 crowd who compose the richest generation to ever walk the face of the earth and whose assets (stocks and house prices) are being propped up via money printing. I think you mean the over 65 crowd. |

If Visa or whoever waged a war on BTC and legit took it down and screwed everything up, there isn't really any law that they violated is there? I am not sure if there is or not but it doesn't sound like there is yet anyway.
IIUC, the "51% attack" is a double-spend attack. That is, if the attack is successful, it allows the attacker to replace the last few blocks with his own new blocks, which re-spend the coins that already appeared as inputs in a transaction in a block that will now be orphaned. In order to profit from such an attack, the coins spent in the orphaned block must be exchanged for something (such as fiat, or a balance in an exchange that is later withdrawn). This would clearly be fraud, and there are already laws against that. The "51% attack" cannot "screw everything up", only those transactions that are double-spent. Of course there is the secondary effect of public relations for Bitcoin, which admittedly could be "screwed up." That's a good point. It just means that Bitcoin is not 100% fraud proof. It just costs millions of dollars worth of equipment and energy to perpetrate something that can still be traced by shipping records, electric bills, and invoices. It's a good thing that Bitcoin is Proof of Work, because there are real world ways to keep it honest. |

I think Stacey was there to keep them from losing their self control.

How secure would it be to use these at a print shop or other public printer?

I'm waiting for the 51% attack, where they sell 51% ownership to a big bank.

One of the biggest grudges people have with purely PoS coins are that the coins are unfairly distributed. Side note: I don't agree with this line of thinking, as everyone has a chance to invest in IPOs if they'd like. This same argument could also be applied to early adopters of Bitcoin... but I am getting sidetracked. I think it is a shame something as silly as this could hold back purely PoS coins, as I feel they are a step up from purely PoW coins which consume much more energy to secure their block chains and waste processing power.
Right from the start your premise is false. The problem with a PoS coin as a global currency is that you cannot guarantee that a central authority cannot gain and hold majority stake permanently. With that power, they can discretely and secretly reverse transactions. This is fine for a local currency, because nobody trusts their local governments anyway and they can be replaced. You would not want a PoS coin as a store of value. |

feet, not kilometers.
Ah, mixed up imperial and metric units - always confusing, how should he know that km and ft are not approximately the same thing? (actually, connection distances of up to 300km have been reported for Wifi technology: http://en.wikipedia.org/wiki/Long-range_Wi-Fi) Onkel Paul I imagine if you use a large dish antenna you would be able to achieve great distances. So I suppose it is theoretically possible to get 300 km distance. |

Those Rai stones are interesting, and what I find peculiar is how everyone seems to think they "Carved" the stones out of Limestone. In fact, the majority of Large Stone formations like the Pyramids are believed to be carved out of solid rock.
Does this make sense? When Limestone is used to make concrete and can be formed easily?
Look at those Rai stones and the center hole is perfect while many of them are irregular shaped disks. If they were experts at carving stone then why would they make them so imperfect?
It's because they poured the concrete around a pole and it dried.
There is no evidence that they had concrete technology. A center hole is round if you drill. The stones themselves are the evidence. Concrete is made from Limestone and they quarried the limestone from the islands 400 miles away. Tell me these don't look like poured concrete slabs:  They don't. Besides, if they had concrete, then where are their ancient roads and office buildings? Building roads and office building take money and, as you can see, Yap was in short supply of currency, so they invented deflation instead.  |

Given the irreversibility of Bitcoin, I am surprised that MC wants to be exposed to them. Interestingly, I don't see them including coinage, though barter is also confusing. They currently honor chargeback claims. Will they stop doing so? If a payment is a combination of credit, barter, and bitcoins, how would they handle a chargeback claim? This is a perplexing financial device they are building.
