    1. Blockchains are NOT about cutting computational costs (at least relative to centralized servers). Blockchains are about incurring a sacrifice in the form of INCREASED computational costs to achieve a *decrease* in *social costs*.

      <big>评:</big><br/><br/>「区块链以增加计算成本为代价来降低社会成本」,这样的论断让人联想到前几年有关新能源汽车的讨论。新能源汽车的 per unit actual consumption 不一定比内燃机车辆低,但人们寄厚望于它的 social benefit。<br/><br/>我们现在已经知道,区块链会把人类带向一个新世界。试追问:区块链就是这个「世界」本身吗?又或者只是新世界的运行规则?大脑在变得更加聪明,而思维在变得更加固化,已然练就了一种表述:每个世界都要有自己的运行法则。<br/><br/>在上述疑问尚无共识之前,我们不妨先关注一下特斯拉的股价?

First Read's Morning Clips: It's Nev-ADDD-ah, not Nev-AHHHH-dah Share Share Tweet Share Email Print Comment advertisement OFF TO THE RACES: It's Nev-ADDD-ah, not Nev-AHHHH-dah Donald Trump's attempt to pronounce "Nevada" in the Silver State last night didn't go well. Tim Kaine praised his own Tuesday night debate performance. Trump says he's "getting a lot of credit" after Mike Pence's widely-praised debate. Pence is taking heat from Latinos after his "Mexican thing" remark. From the Washington Post: "Sen. Tim Kaine may have awakened Wednesday to poor reviews after the first and only vice-presidential debate, but his acerbic performance in Farmville, Va., revealed that the Clinton campaign's strategy for these debates extends far beyond the stage. Armed with pre-planned Web videos, television ads and tweets, the campaign has used key debate moments this week and last as a cudgel against the Republican ticket, showing a level of discipline and organization largely absent from Donald Trump and Indiana Gov. Mike Pence's campaign." Trump said yesterday: "They say Donald Trump loves Putin. I don't love, I don't hate. We'll see how it works." And here's Trump on the issue of Yucca Mountain: "Number one is safety and it is a little too close to major population, so I will take a look at it and I will have an opinion." The New York Times does a deep dive into Trump's business ventures. "Of the roughly 60 endeavors started or promoted by Mr. Trump during the period analyzed, The Times found few that went off without a hitch. One-third of them either never got off the ground or soon petered out. Another third delivered a measure of what was promised — buildings were built, courses taught, a product introduced — but they also encountered substantial problems, like lawsuits, government investigations, partnership woes or market downturns." Here's how Pennsylvania boosted its swing-state status, according to the Washington Post. An interesting data point from PRRI/The Atlantic: "White likely voters who still live in their hometown strongly prefer Donald Trump over Hillary Clinton (57 percent vs. 31 percent), while nearly half (46 percent) of those who live more than a two-hour drive away from their hometown are supporting Clinton compared to 40 percent who are supporting Trump." The Atlantic endorsed Hillary Clinton, only the third time it has weighed in on a presidential election since 1857. Via POLITICO: With hopes in Pennsylvania fading, Trump is hoping to make gains in the Mountain West. From the AP: "Donald Trump once called data "overrated" in politics. But with Election Day swiftly approaching, the Republican presidential nominee is spending millions of dollars on data and digital services in an effort to land donations and win over voters. Ushering Trump toward a more analytical approach are Jared Kushner, Trump's son-in-law and adviser, and Brad Parscale, the campaign's digital director and a veteran Trump Organization consultant." Sean Hannity is accusing Megyn Kelly of supporting Hillary Clinton. "Republican presidential nominee Donald Trump has throughout his career given campaign contributions to state attorneys general while they weighed decisions affecting his business, a review of his political donations shows," notes the Wall Street Journal. From the New York Times yesterday: "The F.B.I. secretly arrested a former National Security Agency contractor in August and, according to law enforcement officials, is investigating whether he stole and disclosed highly classified computer code developed by the agency to hack into the networks of foreign governments. The arrest raises the embarrassing prospect that for the second time in three years, a contractor for the consulting company Booz Allen Hamilton managed to steal highly damaging secret information while working for the N.S.A." What will happen to Merrick Garland's nomination in December? The

      The first thing i noticed when i got to the NBC website was that all of the political articles are about Trump. That really says something about the style of politics that are alive in the U.S. today. Although the article title talks about "Nevada" and how Trump says the State's name, it actually takes a deeper look into Trump's past business dealings and political affiliations. As opposed to the Fox news article that actually did focus on his pronunciation of Nevada. On top of that the author in this article goes after Trump's VP candidate as well as others that are in Trump's campaign committee. This article seemed more like an attack on trump rather than a criticism.
