"Employees worry that, should Signal fail to build policies and enforcement mechanisms to identify and remove bad actors, the fallout could bring more negative attention to encryption technologies from regulators at a time when their existence is threatened around the world. "The world needs products like Signal - but they also need Signal to be thoughtful," said Gregg Bernstein, a former user researcher who left the organization this month over his concerns. "It's not only that Signal doesn't have these policies in place. But they've been resistant to even considering what a policy might look like.""

""Western partners trusted me to distribute stuff, give them actionable feedback and then adapt the product to Ukrainian conditions," he explains during a trip back to San Francisco to harness help from local software engineers. He still spends part of his time in the fragments of the Donbas region that remain under Ukrainian control, so that he can observe his "customers" - Ukrainian soldiers - in action, in order to develop products they can use. "I like to say this is the world's first open-source war," says Oleg Rogynskyy, 35, another Ukrainian who runs a Silicon Valley start-up. He is also helping the Ukrainian cause and exchanging ideas with other computing engineers on social media sites, message groups such as Signal, and GitHub, the platform where coders exchange ideas."

"The folks at Signal are taking one of the four post-quantum cryptography algorithms that have been chosen by the US National Institute of Standards and Technology to withstand attacks by quantum computers, but instead of using it to replace their existing public-key encryption system, they are layering the new algorithm on top of what they already have. "We are augmenting our existing cryptosystems," they say, "such that an attacker must break both systems in order to compute the keys protecting people's communications." And they will be rolling out this augmented system to all users in the next few months."

"There are clear indications that the UK government is now actively considering use of the technology as a way of easing the lockdown. If this signals an outbreak in Whitehall of tech "solutionism" - the belief that for every problem there is a technological answer - then we should be concerned. Tech solutions often do as much harm as good, for example, by increasing social exclusion, lacking accountability and failing to make real inroads into the problem they are supposedly addressing."

"In quantum cryptography, a sender uses a cryptographic key encoded in a quantum signal to encrypt a message. According to the laws of quantum mechanics, if someone tried to intercept the key, they would destroy it."

"Ministers have paused a planned update to the NHS Covid-19 app after Apple and Google blocked it from their stores over privacy violations. The app, which aids contact tracing in England and Wales, uses technology built by the Silicon Valley companies to track interactions between users with their bluetooth signals and venue "check-ins"."

"Humming does not sit easily with the way we imagine technology, but it highlights a crucial truth about how humans navigate the world of work, in offices, online or anywhere else: even if we think we are rational, logical creatures, we make decisions in social groups by absorbing a wide range of signals. And perhaps the best way to understand this is to employ an idea popularised by anthropologists working at companies such as Xerox during the late 20th century, and since used by Beunza and others on Wall Street: "Sense-making"."

"The long-running issues of traceability, transparency and enforcement were colourfully illustrated in September 2017 when a group of investigators from the Basel Action Network (BAN) - a non-for-profit group that monitors compliance with the 1989 United Nations Basel Convention on the trade of hazardous wastes - attempted to learn where exactly Australia's e-waste was going. The group fitted 35 old CRT televisions, LED monitors and printers with GPS devices of a special make. Out of this sample the team quickly focused on the fate of three LCD screens dropped at Officeworks storefronts around the Brisbane metro area. Hayley Palmer, BAN's chief operating officer, was on the team that followed where they went afterwards. As the signals left the country, Palmer, her nine-month-old and a colleague tracked the monitors to a warehouse in Hong Kong and then on to an illegal dump-yard in a rural part of Thailand where they talked their way inside."

"Their tools analyze content using sophisticated algorithms, picking up on subtle signals to distinguish the images made with computers from the ones produced by human photographers and artists. But some tech leaders and misinformation experts have expressed concern that advances in A.I. will always stay a step ahead of the tools. To assess the effectiveness of current A.I.-detection technology, The New York Times tested five new services using more than 100 synthetic images and real photos. The results show that the services are advancing rapidly, but at times fall short."

"Now that might be about to change. The arrival of OpenAI's ChatGPT, a program that generates sophisticated text in response to any prompt you can imagine, may signal the end of writing assignments altogether-and maybe even the end of writing as a gatekeeper, a metric for intelligence, a teachable skill. If you're looking for historical analogues, this would be like the printing press, the steam drill, and the light bulb having a baby, and that baby having access to the entire corpus of human knowledge and understanding. My life-and the lives of thousands of other teachers and professors, tutors and administrators-is about to drastically change."

"Disappearing messages is a feature offered by apps like Signal and WhatsApp, giving users the option to have conversations that self-destruct. They're not the only platforms that have tapped into the allure of digital ephemerality. The very premise of Snapchat is that content is only viewable for a short window; Instagram stories similarly vanish after 24 hours. Those who are chronically online may remember the last day of X's own foray into expiring content called "fleets", when countless users threw whatever remaining posting-caution they had to the wind to share revealing, horny or outright unhinged posts for one final hurrah before the feature itself vanished. I can't tell you what people posted or link you to evidence of this because, well, it's gone."

"The Purdue researchers have created Electro-Quasistatic Human Body Communication (EQS-HBC) which uses low-frequency, carrier-less broadband transmission, and so keeps the signal almost entirely within the human body. That means data from pacemakers and other implantable medical devices would only be readable a handful of centimetres outside the wearer."

"Increasing numbers of implantable medical devices are now gaining internet connectivity, giving doctors the ability to monitor patients health remotely, and even update the devices to tweak a treatment plan. Unfortunately, that flexibility offers a way for hackers to hijack that hardware, and even potentially make changes to the way the devices work. While so far no attacks have been successful, proof-of-concept attacks have been available for years"
