然而我知道,你们这一代人不同于过去的任何一代人,极其渴望体会不同以往的人生。所以,在你们离开学校之际,我要向你们介绍几条显而易见、却容易忽略的真理,帮助你们以略微不同的角度来看待生活,而不是仅凭一叠薪金来认识世界:
“这是一个目标,也是我们想经历的事情”,库里赛后表示。“这将会是一个巨大的成就,因为做一些在联盟历史上还从未发生过的事情,感觉会是非常与众不同的。你永远也不会知道,这种机会是否还会再次来过。在取得这一连串的胜利过程当中,有许多许多的不可掌控的因素,特别是在赛季的开局阶段。”

尽管辩论被认为是仅仅关于外交政策的,但国内关注从未远离表面,候选人抓住每一个机会围绕他们的竞选演说在经济和税收方面给予攻击。之后在旋转屋也是一样,两个竞选团队很快分配着辩论评论,同时转到摇摆州中的竞争状态分析。

America faces a voting security crisis in 2020. Here’s why – and what officials can do about it.

Paperless voting machines are just waiting to be hacked in 2020. And “upgrading” to paper-based voting machines may sound like an oxymoron, but it’s something cybersecurity experts are urging election officials across the country to do. A POLITICO survey found that in 2018, 鉴于《速度与激情7》定于2014年夏季在各大院线上映,“巨石强森”将再次迎来丰硕的一年。凭借影片《海格力斯》(Hercules)他还可以做得更好。该片讲述的是这位神话英雄在完成其著名的12件苦差后的生活,极有可能拍摄续集。如果该部影片也能取得巨大成功,那么约翰逊在2014年将获得丰厚的票房收入。 — and almost half of the counties that responded to the survey said they don’t plan on changing that ahead of 2020. Security experts said paperless voting machines are vulnerable to hacking because they leave no paper trail and there’s no way to reliably audit the results when an error occurs.

Thousands of Redditors joined us as cybersecurity reporter Eric Geller and voting security expert and University of Michigan professor J. Alex Halderman [grɑ:nt]. We chatted about voting methods in various countries from the U.S. to India, how much the transition to paper ballots would cost, and even "Star Wars."

Honda has recalled more than 10 million vehicles in the U.S. to fix a potentially fatal defect in air bags made by Japanese supplier, Takata. The air bag inflators can rupture after a crash and injure occupants with shards of metal. Honda has confirmed three deaths and 48 injuries in connection with such incidents.


Question
What are the most convincing arguments against internet voting?
Answer
Internet voting systems tend to be fragile. A few years ago, Washington, D.C., built an online voting system and invited anyone to try to hack in during a mock election. It took me and my students only about 48 hours to gain full control and change all the votes, and the election officials didn't notice anything was wrong until somebody noticed a musical "calling card" we left for them to find. — Halderman


Question
Why are so many politicians against paper ballots?
Answer
Politicians want to give voters what they want, and voters enjoy electronic voting machines because they're familiar and convenient (they're basically giant iPads). Some politicians also harbor mistaken beliefs about the security and reliability of paper ballots compared to electronic devices. In some cases, politicians aren't so much against paper ballots as they are against replacing what they have with something else, for cost and logistical reasons. — Geller


Question
How much money would it cost to have every poll location "upgraded" to paper ballots?
Answer
Surprisingly little! I testified to Congress about this earlier this year and concluded that it would cost about $370 million to implement paper ballots in every U.S. jurisdiction that lacks them today. Once you have paper ballots, risk-limiting audits are cheap. Auditing every federal race would cost less than $25 million a year. $370 million might seem like a lot of money, but this is by far the cheapest major cybersecurity challenge to solve. And we can do it without any technical breakthroughs. — Halderman


Question
What is the point of using electronic voting in first place? Shouldn't the voting system use something easily understandable like paper and pencils?
Answer
Electronic voting is much more convenient, especially in today's iPhone world. In addition, many voters with disabilities cannot vote with paper and pencils. This is one of the biggest reasons electronic voting machines — sometimes paperless ones — persist in many places. They offer voters with disabilities a way to vote independently and privately, as is their constitutional right. — Geller


Question
What are the best policy measures needed to protect elections?
Answer
The U.S. desperately needs stronger national leadership on election security. The points I'd most like to see are:

  • The report also found traffic congestion in first-tier cities such as Beijing, Shenzhen, Guangzhou and Shanghai have stopped getting worse with local government efforts.
  • 25 July
    谎言4:太感谢了!我很喜欢!说谎原因:告诉别人他们送的礼物一团糟会让我看起来像是冷血的混蛋。
  • Arriving at the stage, he said: "What an incredible honour, that meant a lot. Two years ago we found ourselves submerged deep in nature with all its complications and all the beauty that it gave us cinematically.
    "This year is a key period for Tibet's war against poverty. We will continue mapping out policies and plans in accordance with varying situations and causes of poverty and increasing funds," said Lu.
    The charges of Russian hacking and Mr Trump’s evident defects of experience, judgment and character show that the college has not proved the bulwark Mr Hamilton hoped for.

Question
Do voting machines have to comply with any cybersecurity mandates (e.g., NIST)? Who approves their cybersecurity plans?
Answer
The National Institute of Standards and Technology and the Election Assistance Commission collaborate on a set of voluntary standards that states can choose to adopt and make mandatory. But there are no federal regulations on voting technology vendors. Only state regulations. Similarly, only state governments have the authority to require vendors to show them their cybersecurity plans. The federal government does not inspect them in that way. — Geller


Question
What’s the best way to overcome the “hanging chad” issue with paper ballots that we saw during the presidential election in 2000?
Answer
Manufacturers of paper ballots have significantly improved the design of these ballots since 2000. No voting method is perfect, but research from 2012 suggests the error rate is between 1 percent and 2 percent. The vast majority of the voting problems I heard about on Election Day 2018 were related to electronic voting machines rather than paper ballots or their scanners. We've come a long way since 2000. — Geller


Question
Wouldn't blockchain technology eradicate the ability for elections to be tampered with?
Answer
Blockchain's great for maintaining a distributed ledger, and that might be useful for some election applications (like voter registration), but it's far from the hardest security challenge facing elections. Say you wanted to build a blockchain-based online voting system. You'd need to be really sure the blockchain system itself is secure, but you'd also need to figure out how to authenticate voters securely and how to guard against attacks that compromise voters' client devices and modify votes before they're posted on the blockchain. These are really hard problems, as evidenced by frequent attacks that steal cryptocurrency by stealing passwords, installing malware on clients, or compromising exchanges. — Halderman


Question
I live in an area where we will be using paperless voting (Tennessee). Should I even bother voting?
Answer
YES! Please vote! We're talking about serious risks, but that's all they are: things that could potentially go wrong. If you don't participate, you're guaranteeing that your vote won't count, and that's a win for attackers who want to undermine American democracy. — Halderman


Question
Whatever happened to the good days, when you just put a nice, smooth rock into a hat to vote?
Answer
We'd need a lot more rocks and much bigger hats. — Geller
