"Big data and artificial intelligence are some of today's most popular buzzwords. Both are promised to help deliver insights that were previously too complex for computer systems to calculate. With examples ranging from personalised recommendation systems to automatic facial analyses, user-generated data is now analysed by algorithms to identify patterns and predict outcomes. And the common view is that these developments will have a positive impact on society."

"The groundbreaking artificial intelligence system, developed by the AI-outfit DeepMind with Moorfields eye hospital NHS foundation trust and University College London, was capable of correctly referring patients with more than 50 different eye diseases for further treatment with 94% accuracy, matching or beating world-leading eye specialists."

"Google says that will prevent the company from remembering where you've been. Google's support page on the subject states: "You can turn off Location History at any time. With Location History off, the places you go are no longer stored."

That isn't true. Even with "location history" paused, some Google apps automatically store time-stamped location data without asking."

"Cybersecurity experts have warned for years that malfeasance, technical breakdown or administrative incompetence could easily wreak havoc with electronic systems and could go largely or wholly undetected. This is a concern made much more urgent by Russia's cyber-attacks on political party servers and state voter registration databases in 2016 and by the risk of a repeat - or worse - in this November's midterms.

" Critics have pointed out that the old computing adage "garbage in, garbage out" also applies to ML. If the data from which a machine "learns" is biased, then the outputs will reflect those biases. And this could become generalised: we may have created a technology that - however good it is at recommending films you might like - may actually morph into a powerful amplifier of social, economic and cultural inequalities."

"Rekognition indicated high confidence that 28 members of the current Congress were known arrestees. It was wrong in every case. The false positives disproportionately targeted racialized members of Congress.

This, finally, has Congress's attention: members of Congress have sent some pointed questions to Amazon about its Rekognition tool and given them a deadline of Aug 20 to respond. They've also requested an immediate meeting with Jeff Bezos to discuss the topic in depth."

"The bitcoin blockchain was created, in part, to address this historical weakness. After the 21 millionth bitcoin is mined, in around 2140, the system will produce no more."

"They've moved "authoritative sources" to the top search results. The question we need to ask is: "How does this play out in the Real World?" In the real world it means that the worldview, the political bias, the social preferences, the positions taken in various ideological and scientific controversies - as decided by top Google Executives - have been virtually hard-coded into Google's search algorithms. No longer is Google returning "unbiased and objective results"."

Singhealth, a Singaporean public health service, suffered the worst breach in Singaporean history, losing control of 1.5 million peoples' data; included in the breach was prescription data on 160,000 people, including Singapore's prime minister, Lee Hsien Loong."

"Kim Zetter asked them, on behalf of the New York Times, if their products shipped with backdoors allowing remote parties to access and alter them over the internet, they told her unequivocally that they did not engage in this practice.

But now, in a letter to Senator Ron Wyden [D-OR], they admit that they lied, and that they "provided pcAnywhere remote connection software … to a small number of customers between 2000 and 2006.""

"About 70% of the world's online traffic is reckoned to pass through Loudoun County.
But there is a big problem, centred on a power company called Dominion, which supplies the vast majority of Loudoun County's electricity. According to a 2017 Greenpeace report, only 1% of Dominion's total electricity comes from credibly renewable sources:"

"A new artificial intelligence (AI) program recreated the periodic table of elements in just a few hours.

It took nearly a century of trial and error for human scientists to organize the periodic table of elements, arguably one of the greatest scientific achievements in chemistry, into its current form."

"It's an old cliché of security researchers: fingerprints might appear more secure than passwords. But if your password gets stolen, you can change it to a new one; what happens when your fingerprint gets copied?"

"Anouk van Maris, a robot cognition specialist who is researching ethical human-robot interaction, has found that comfort levels with robots vary greatly depending on location and culture. "It depends on what you expect from it. Some people love it, others want to run away as soon as it starts moving," she says. "The advantage of a robot that looks human-like is that people feel more comfortable with it being close to them, and it is easier to communicate with it. The big disadvantage is that you expect it to be able to do human things and it often can't.""

"The algorithm behind what3words took six months to write. Sheldrick worked on it with two friends he had grown up with. Mohan Ganesalingham, a maths fellow at Trinity College, Cambridge, and Jack Waley-Cohen, a full-time quiz obsessive and question-setter for Only Connect. After the initial mapping was complete, they incorporated an error-correction algorithm, which places similar-sounding combinations a very long way apart."

"Flooding involves deluging the citizen with a torrent of information - some accurate, some phoney, some biased - with the aim of making people overwhelmed. In a digital world, flooding is child's play: it's cheap, effective and won't generate backlash. (En passant, it's what Russia - and Trump - do.)

In her book, Roberts provides abundant evidence of how the Chinese authorities deploy these three techniques."

"In October 2016, algorithms reacted to negative news headlines about Brexit negotiations by sending the pound down 6% against the dollar in under two minutes, before recovering almost immediately. Knowing which particular headline, or which particular algorithm, caused the crash is next to impossible. When one haywire algorithm started placing and cancelling orders that ate up 4% of all traffic in US stocks in October 2012, one commentator was moved to comment wryly that "the motive of the algorithm is still unclear"."

"The animal matchmaking program isn't just for gorillas, and it takes some things into consideration that probably aren't on Tinder's radar. It scores every animal on a variety of traits (and when we say "every" animal, we mean there's an entry for each flamingo in each American zoo), including social skills, age, experience, family history, and interpersonal relationships. Oh, and genetic diversity. Animals with rare genes are more valuable to breeding programs because their offspring will introduce more genetic diversity into the dating pool."
