the Redmond, Washington, giant is working with Blockstack Labs and ConsenSys to leverage their current Bitcoin and Ethereum-based identity solutions, Blockstack and uPort. Through this open source collaboration, Microsoft and its partners intend to produce a cross-chain identity solution that can be extended to any future blockchains or new kinds of decentralized, distributed systems.

The idiom "Crossing the Rubicon" means to pass a point of no return, and refers to Julius Caesar's army's crossing of the Rubicon River (in the north of Italy) in 49 BC, which was considered an act of insurrection, treason and a declaration of war upon the Roman Senate. Julius Caesar may have uttered the famous phrase "alea iacta est"—the die is cast—as his army marched through the shallow river.

Monday marks the seven-year anniversary of the first Bitcoin transaction, in which a Florida man paid for two pizzas with the cryptocurrency. The day has become part of folklore, not because of the transaction, but more the price: the man in question paid 10,000 Bitcoins, which today is worth $20 million, for the two pizzas.

Ethereum is an open-source, public, blockchain-based distributed computing platform featuring smart contract (scripting) functionality, which facilitates online contractual agreements.[2] It provides a decentralized Turing-complete virtual machine, the Ethereum Virtual Machine (EVM), which can execute scripts using an international network of public nodes. Ethereum also provides a cryptocurrency token called "ether", which can be transferred between accounts and used to compensate participant nodes for computations performed. Gas, an internal transaction pricing mechanism, is used to prevent spam and allocate resources on the network.[2][3]

well-designed token networks include an efficient mechanism to incentivize network participants to overcome the bootstrap problem that bedevils traditional network development.

Here’s how an ICO typically works: A new cryptocurrency is created on a protocol such as Counterparty, Ethereum, or Openledger, and a value is arbitrarily determined by the startup team behind the ICO based on what they think the network is worth at its current stage. Then, via price dynamics determined by market supply and demand, the value is settled on by the network of participants, rather than by a central authority or government.

Brave, the upstart web browser founded by Mozilla co-founder Brendan Eich, completed an initial coin offering (ICO) today that is likely to be distinguished for its speed and earnings. Overall, the sale for Brave's ethereum-based Basic Attention Token (BAT) generated about $35m and was sold out within blocks, or under 30 seconds.

When the zooming factor is exactly 100%, one CSS pixel equals one device pixel (though the upcoming intermediate layer will take the place of device pixels here.) The image below depicts that.

The reason that CSS pixel ratio was created is because as phones screens get higher resolutions, if every device still had a CSS pixel ratio of 1 then webpages would render too small to see.

devicePixelRatio is the ratio between physical pixels and device-independent pixels (dips) on the device. devicePixelRatio = physical pixels / dips

The drug policy of Portugal was put in place in 2001, and was legally effective from July 2001. The new law maintained the status of illegality for using or possessing any drug for personal use without authorization. However, the offense was changed from a criminal one, with prison a possible punishment, to an administrative one if the amount possessed was no more than a ten-day supply of that substance.

As this chart shows, use had gone up slightly when measured in 2007 (a trend in line with other, similar countries), but has since gone back down. In fact, by two out of three measures, adult drug use is now lower than it was in 2001.

numbers just released from the European Monitoring Centre for Drugs and Drug Addiction paint an even more vivid picture of life under decriminalization: drug overdose deaths in Portugal are the second-lowest in the European Union.

The word "money" is believed to originate from a temple of Juno, on Capitoline, one of Rome's seven hills. In the ancient world Juno was often associated with money.

Perhaps the single most dramatic example of this phenomenon of software eating a traditional business is the suicide of Borders and corresponding rise of Amazon. In 2001, Borders agreed to hand over its online business to Amazon under the theory that online book sales were non-strategic and unimportant. Oops. Today, the world’s largest bookseller, Amazon, is a software company — its core capability is its amazing software engine for selling virtually everything online, no retail stores necessary.

Stuxnet is a malicious computer worm, first identified in 2010, that targets industrial computer systems and was responsible for causing substantial damage to Iran's nuclear program. The software was designed to erase itself in 2012 thus limiting the scope of its effects. The worm is believed by many experts to be a jointly built American-Israeli cyberweapon,[1] although no organization or state has officially admitted responsibility. Anonymous American officials speaking to The Washington Post claimed the worm was developed during the Bush administration to sabotage Iran's nuclear program with what would seem like a long series of unfortunate accidents.

Traditional warfare: Dani tribesmen fighting with spears in the Baliem Valley of the New Guinea Highlands. The highest one-day death toll in those wars occurred on June 4, 1966, when northern Dani killed face-to-face 125 southern Dani, many of whom the attackers would personally have known (or known of). The death toll constituted 5% of the southerners’ population. Photo credit: Karl G. Heider.

Researchers Gurven and Kaplan have estimated that around 57% of hunter-gatherers reach the age of 15. Of those that reach 15 years of age, 64% continue to live to or past the age of 45. This places the life expectancy between 21 and 37 years.[30] They further estimate that 70% of deaths are due to diseases of some kind, 20% of deaths come from violence or accidents and 10% are due to degenerative diseases.

anthropologists Richard Borshay Lee and Irven DeVore suggested that egalitarianism was one of several central characteristics of nomadic hunting and gathering societies because mobility requires minimization of material possessions throughout a population. Therefore, no surplus of resources can be accumulated by any single member.
