Better encryption, but will anyone implement it?
Fitting Forward Secrecy into Today's Security Architecture
Forward Secrecy’s day has come – for most. The cryptographic technique (sometimes called Perfect Forward Secrecy or PFS), adds an additional layer of confidentiality to an encrypted session, ensuring that only the two endpoints can decrypt the traffic. With forward secrecy, even if a third party were to record an encrypted session, and later gain access to the server private key, they could not use that key to decrypt a session protected by forward secrecy. Neat, huh?
Forward secrecy thwarts large-scale passive surveillance (such as might be conducted by a snooping nation state or other well-resourced threat actor) so it is seen a tool that helps preserve freedom of speech, privacy, and other rights-of-the-citizenry.
It is supported and preferred by every major browser, most mobile browsers and applications, and nearly 90% of TLS hosts on the Internet, according to a recent TLS Telemetry report (PDF). The crypto community applauds forward secrecy’s broad acceptance today.
Of course there’s a snag, for some.

Something for my students to debate.
Facebook and Free Speech
In the weeks since Mark Zuckerberg’s testimony to Congress, Facebook has made two important policy announcements. The company released a document explaining what posts and accounts it removes on the basis of its internal rules, known as “community standards,” and it engaged outside consultants to review the social media platform’s impact on various communities. The company also released its first transparency report on the enforcement of its community standards.
These are all welcome developments, but they lay bare a fundamental question raised by Zuckerberg himself: What obligations does the public want companies to fulfill when deciding which speech deserves a place on the Internet and social media? The Supreme Court recently called the internet and social media platforms “the most important places…for the exchange of views,” so the question is not simply an academic exercise.

Is Facebook the only one doing this?
Facebook users worldwide are being asked to review their privacy settings as GDPR looms
Facebook users will soon see a notice on their accounts asking them to review their privacy settings, as the company prepares for the rollout of new data protection rules in Europe.
The alert, which starts appearing this week, asks users across the globe to reassess their preferences for the types of personal data Facebook can use for ad targeting and whether they'll submit to facial recognition. They'll be given the chance to review the information they share on their profiles, including political and religious affiliations and relationship status.
Consumers will see how Facebook uses their activity to send targeted ads and what the company does with its facial recognition tools. Facebook will show them which features they currently have turned on, allowing them to opt out if they choose.
Though Facebook is facing a barrage of criticism in the U.S. over data protection, following the Cambridge Analytica scandal in March, this week's notice is in response to the General Data Protection Regulation in Europe. The alert has already appeared for European users, but this time it is getting a worldwide rollout.

Lots of Facebook action today.
Exclusive: Facebook Opens Up About False News
… Facebook is today making three important announcements on false news, to which WIRED got an early and exclusive look.
… The first new announcement is a request for proposals from academics eager to study false news on the platform. Researchers who are accepted will get data and money; the public will get, ideally, elusive answers to how much false news actually exists and how much it matters. The second announcement is the launch of a public education campaign that will utilize the top of Facebook’s homepage, perhaps the most valuable real estate on the internet. Users will be taught what false news is and how they can stop its spread. Facebook knows it is at war, and it wants to teach the populace how to join its side of the fight. The third announcement—and the one the company seems most excited about—is the release of a nearly 12-minute video called “Facing Facts,” a title that suggests both the topic and the repentant tone.

United Kingdom Att’y General’s Speech on International Law and Cyber: Key Highlights
On Wednesday, the United Kingdom’s Attorney General, Jeremy Wright, QC MP, gave a speech at Chatham House on the role of international law in cyberspace. It is the first official statement of the UK’s overarching view on the topic, including on some specific issues that are at the center of international policy and debate (the speech can be found here.) Here are eight key points:
First, it is important for states to publicly articulate their understanding of international law, especially in cyberspace. Wright acknowledged that rapidly changing technology and developing norms made clear rules difficult, but he warned against allowing cyberspace to become a “grey area.”

Twitter adds candidate labels ahead of midterm elections
Twitter will start adding labels to the profiles of candidates running in the 2018 midterm elections after May 30th.
The label, which will apply to all candidates running for state governor, U.S. Senate or U.S. House of Representatives, will contain the office the candidate is running for, the state the office is located in, their district number (when applicable), and other identifying information.
  • The label will be marked with a small icon of a government building, and will appear on the Twitter page of the candidate as well as alongside all tweets sent or retweeted by the account.

We keep getting smaller. Is subcutaneous next?
I’m not into watches or wristbands, but for the last few weeks I’ve been wearing a fitness tracker on my finger. It knows how long I sleep and detects when I walk or run, and all I’ve gotta do is wear it like jewelry and forget about it.
The device is the Motiv Ring. Its features and its iOS app are minimalist compared to what a Fitbit or an Apple Watch can do, which is part of why I like it.
… The ring doesn’t have a screen, just a tiny light that changes color when it charges or when it’s syncing with your phone. (You can force it to sync by spinning the ring around your finger, or ask it to ring your phone by spinning one way and then the other.) The ring doesn’t need to sync constantly, so you don’t need to worry if your phone dies or if you’d rather go to the gym without your phone. It can hang onto a few days’ data if needed.

Tracks with my student opinions.
AAA: American Trust in Autonomous Vehicles Slips
Following high-profile incidents involving autonomous vehicle technologies, a new report from AAA’s multi-year tracking study indicates that consumer trust in these vehicles has quickly eroded. Today, three-quarters (73 percent) of American drivers report they would be too afraid to ride in a fully self-driving vehicle, up significantly from 63 percent in late 2017. Additionally, two-thirds (63 percent) of U.S. adults report they would actually feel less safe sharing the road with a self-driving vehicle while walking or riding a bicycle.

Perspective. Maybe the next Indian billionaire is in my classroom.
Why Walmart’s Flipkart Deal Will Spur Entrepreneurship in India
Walmart’s agreement on June 9 to purchase 77% of Flipkart for $16 billion mints two engineer billionaires in India. Binny Bansal and Sachin Bansal, who co-founded Flipkart and who are not related, each reportedly own about 5% of the Indian online retailer. They will have a net worth about $1 billion when the transaction with Walmart is completed later this year. It will mark a major business success for professionals in India, outside the information technology businesses. The example of the founders, including their initial failures, will inspire more professionals in India to risk starting an enterprise.
Flipkart is India’s largest online retailer with an estimated 40% market share. Amazon, its main and tough competitor, has about a third of the market.

Perspective. Too trusting or setting the President up for further legal action?
Judge rules Trump can't block users on Twitter
A federal district court judge on Wednesday ruled that President Trump can't block people from viewing his Twitter feed over their political views.
Judge Naomi Reice Buchwald, of the U.S. District Court for the Southern District of New York, said President Trump’s Twitter account is a public forum and blocking people who reply to his tweets with differing opinions constitutes viewpoint discrimination, which violates the First Amendment.
… Buchwald, who was appointed by former President Clinton, rejected Trump’s argument that the First Amendment does not apply in this case and that the president’s personal First Amendment interests supersede those of the plaintiffs.
She suggested in her 75-page opinion that Trump could have ignored his opponents’ reply tweets.
… But Buchwald did not order Trump or Scavino to unblock the individual plaintiffs in the case or prohibit them from blocking others from the account based on their views as the plaintiffs’ had asked.
She said a declaratory judgment should be sufficient.
“Because no government official is above the law and because all government officials are presumed to follow the law once the judiciary has said what the law is, we must assume that the President and Scavino will remedy the blocking we have held to be unconstitutional,” Buchwald wrote.

Perhaps this is part of the cost to acquire a new CEO?
Chipotle Mexican Grill to close Denver headquarters, relocate staff to California and Ohio
The company said in a news release the headquarters will move to Newport Beach, Calif. and other functions within the Denver office will move to the company’s existing office in Columbus, Ohio.
… The news comes as a surprise to some in Denver, as the company announced in December it was moving its headquarters to a new office tower downtown that was still under construction.
"We wish @ChipotleTweets all the best. We want their existing employees to know we have services that can help them find new jobs," Gov. John Hickenlooper tweeted Wednesday afternoon. His wife, Robin, has sat on Chipotle's board of directors since December 2016.
It signed a 15-year lease for five floors of a 40-story skyscraper located on 15th Street between Arapahoe and Lawrence streets. The status of the lease is currently unclear, though the building held its grand opening in recent months.
The CEO at the time, Steve Ells, said: “Our roots are here, and this contemporary, collaborative and modern space will position us to look ahead to the next 25 years.”
… Paul Seaborn, an assistant professor of management at the University of Denver, has watched Chipotle's performance closely and co-wrote a case study last year for an international competition that focused on the key challenges facing the company. He said Chipotle's new CEO is cooking up a culture shock with this latest move.
… Seaborn also said he believes there are no real benefits to moving the headquarters to Newport Beach other than the new CEO's own connections to California. As the former CEO of Taco Bell its headquarters are in nearby Irvine, California.
"This seems much more of a personal management decision," said Seaborn. "This particular move is going to create a big question around retention and who are the key employees that they feel are really pushing the company forward and can they get them to move to California."

Cake shop hilariously censors Latin phrase on US graduate's cake
Cara Koscinski ordered a graduation cake for her 18-year-old son Jacob, who graduated with an impressive 4.89 grade point average, The Washington Post reports.
Ms Koscinski had ordered the cake online from cake shop Publix.
She wanted it to say: "Congrats Jacob! Summa Cum Laude, Class of 2018." The Latin phrase translates in English to "with the highest distinction".
However Publix's online system auto-corrected the middle Latin word, picking it up as bad language.
