Billboards are using sensors to identify, target and track individuals / Boing Boing - 0 views

  •  
    "I can't believe this has to be said (again), but cyberpunk was meant as a warning, not a business plan. It turns out that you need very few identifiers to make a guess about who a person standing in front of a billboard is, especially when you can suck data out of their phones. Throw in data about how long you stand in front of a billboard and you've got metrics that advertisers can use to tune their campaigns."

5 Real World Problems That Are Straight Out Of Black Mirror - 0 views

  •  
    "Thanks to a map that shows the jogging habits of the 27 million people who use Fitbits and the like, we can see splotches of activity in otherwise dark areas, like Iraq and Syria. Some of those splotches are known American military sites full of exercising soldiers, and some, by extrapolation, are sites that the military would rather keep unknown. One journalist saw a lot of exercise activity on a Somalian beach that was suspected to be home to a CIA base. Someone else spotted a suspected missile site in Yemen, and a web of bases in Afghanistan were also revealed."

    "Apart from biases in the training databases, it's hard to know how well face-recognition systems actually perform in the real world, in spite of recent gains. Anil Jain, a professor of computer science at Michigan State University who has worked on face recognition for more than thirty years, told me, "Most of the testing on the private venders' products is done in a laboratory environment under controlled settings. In real practice, you're walking around in the streets of New York. It's a cold winter day, you have a scarf around your face, a cap, maybe your coat is pulled up so your chin is partially hidden, the illumination may not be the most favorable, and the camera isn't capturing a frontal view.""

Electricity needed to mine bitcoin is more than used by 'entire countries' | Technology... - 0 views

  •  
    "Bitcoin mining - the process in which a bitcoin is awarded to a computer that solves a complex series of algorithms - is a deeply energy-intensive process. "Mining" bitcoin involves solving complex math problems in order to create new bitcoins. Miners are rewarded in bitcoin. Earlier in bitcoin's relatively short history - the currency was created in 2009 - one could mine bitcoin on an average computer. But the way bitcoin mining has been set up by its creator (or creators - no one really knows for sure who created it) is that there is a finite number of bitcoins that can be mined: 21m. The more bitcoin that is mined, the harder the algorithms that must be solved to get a bitcoin become."

Chinese bots had key role in debunked ballot video shared by Eric Trump | China | The G... - 0 views

  •  
    "A Chinese bot network played a key role in spreading disinformation during and after the US election, including a debunked video of "ballot burning" shared by Eric Trump, a new study reveals. The misleading video shows a man filming himself on Virginia Beach, allegedly burning votes cast for Donald Trump. The ballots were actually samples. The clip went viral after Trump's son Eric posted it a day later on his official Twitter page, where it got more than 1.2m views."

Germany seizes US$60 million of bitcoin - now, where's the password? - CNA - 0 views

  •  
    "Bitcoin is stored on software known as a digital wallet that is secured through encryption. A password is used as a decryption key to open the wallet and access the bitcoin. When a password is lost the user cannot open the wallet. The fraudster had been sentenced to more than two years in jail for covertly installing software on other computers to harness their power to "mine" or produce bitcoin. When he went behind bars, his bitcoin stash would have been worth a fraction of the current value. The price of bitcoin has surged over the past year, hitting a record high of US$42,000 in January. It was trading at US$37,577 on Friday, according to cryptocurrency and blockchain website Coindesk."

'Nobody can block it': how the Telegram app fuels global protest | Social media | The G... - 0 views

  •  
    "Telegram, a messaging app created by the reclusive Russian exile Pavel Durov, is suited to running protests for a number of reasons. It allows huge encrypted chat groups, making it easier to organise people, like a slicker version of WhatsApp. And its "channels" allow moderators to disseminate information quickly to large numbers of followers in a way that other messaging services do not; they combine the reach and immediacy of a Twitter feed, and the focus of an email newsletter. The combination of usability and privacy has made the app popular with protestors (it has been adopted by Extinction Rebellion) as well as people standing against authoritarian regimes (in Hong Kong and Iran, as well as Belarus); it is also used by terrorists and criminals. In the past five years, Telegram has grown at a remarkable speed, hitting 60 million users in 2015 and 400 million in April this year. "

With AI translation service that rivals professionals, Lengoo attracts new $20M round -... - 0 views

  •  
    "Most people who use AI-powered translation tools do so for commonplace, relatively unimportant tasks like understanding a single phrase or quote. Those basic services won't do for an enterprise offering technical documents in 15 languages - but Lengoo's custom machine translation models might just do the trick. And with a new $20 million B round, they may be able to build a considerable lead. The translation business is a big one, in the billions, and isn't going anywhere. It's simply too common a task to need to release a document, piece of software or live website in multiple languages - perhaps dozens."

12 unexpected ways algorithms control your life - Tech - 0 views

  •  
    "Admission algorithms can make or break your academic plans. A Washington Post investigation found 44 schools use prediction software to give applicants a score out of 100 for its admissions process. The score considers different aspects of a student's application from test scores, home address, transcripts, and even what websites they've visited. That's all calculated to rate how strong of a match a student is for a school."

    "But Leuthardt, for one, expects he will live to see it. "At the pace at which technology changes, it's not inconceivable to think that in a 20-year time frame everything in a cell phone could be put into a grain of rice," he says. "That could be put into your head in a minimally invasive way, and would be able to perform the computations necessary to be a really effective brain-computer interface.""

Going to e-waste: Australia's recycling failures and the challenge of solar | Waste | T... - 0 views

  •  
    "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."

    ""A full inbox is a constant reminder of what we have not done and can impact our sense of accomplishment," Lukins says. "Inbox Zero is a powerful strategy we can implement to increase our sense of control about our workflow. Each time we achieve a task, we receive a hit of dopamine that is physically reinforcing, and [we] feel the psychological relief of achievement.""

Will blockchain fulfil its democratic promise or will it become a tool of big tech? | J... - 0 views

  •  
    "The problem with digital technology is that, for engineers, it is both intrinsically fascinating and seductively challenging, which means that they acquire a kind of tunnel vision: they are so focused on finding solutions to the technical problems that they are blinded to the wider context. At the moment, for example, the consensus-establishing processes for verifying blockchain transactions requires intensive computation, with a correspondingly heavy carbon footprint. Reducing that poses intriguing technical challenges, but focusing on them means that the engineering community isn't thinking about the governance issues raised by the technology. There may not be any central authority in a blockchain but, as Vili Lehdonvirta pointed out years ago, there are rules for what constitutes a consensus and, therefore, a question about who exactly sets those rules. The engineers? The owners of the biggest supercomputers on the chain? Goldman Sachs? These are ultimately political questions, not technical ones."

Macron accused of authoritarianism after threat to cut off social media | France | The ... - 0 views

  •  
    "Emmanuel Macron is facing a backlash after threatening to cut off social media networks as a means of stopping the spread of violence during periods of unrest. Élysée officials and government ministers responded on Wednesday by insisting the president was not threatening a "general blackout" but instead the "occasional and temporary" suspension of platforms. The president's comments came as ministers blamed young people using social media such as Snapchat and TikTok for organising and encouraging rioting and violence after the shooting dead of a teenager during a police traffic stop in a Paris suburb last week."

'This is an epidemic': inside the Thai clinic taking on westerners' gaming addictions |... - 0 views

  •  
    ""Just like any drug you can never get enough," says Olivia, a 50-year-old British author who describes the frightening experience of "living to play a game". In the depths of her addiction, her physical and mental health were at a low and she accumulated over £30,000 (US$37,500) of debt from in-game micro-purchases. In some cases, gamers can forget to eat or sleep, losing jobs and relationships in the process. In one incident in South Korea, a newborn starved to death while her parents gamed, and last year a 12-year-old Australian boy killed himself amid a gaming addiction."

Facebook asked for nudes to help stop revenge porn and it worked. Can our culture chang... - 0 views

  •  
    "Here's how the program, which has been developed in partnership with SWGfL, a UK-based non-profit behind the Revenge Porn Helpline, works. If you've shared an intimate image with someone and are worried that that person might do something nefarious with it, you can send the images to content moderators at Facebook to be "hashed"- essentially the image is assigned a digital fingerprint. If someone then tries to upload that image to Facebook it can be quickly identified and blocked. It's obviously not a silver bullet for stopping revenge porn, and it requires putting a lot of trust in Facebook and accepting that a random content moderator is going to be looking at your naked photos, but it gives people a little bit of control over their images."

Stack Overflow lays off over 100 people as the AI coding boom continues - The Verge - 0 views

  •  
    "Word of the layoffs comes over a year after the company made a big hiring push, doubling its size to over 500 people. Stack Overflow did not elaborate on the reasons for the layoff, but its hiring push began near the start of a generative AI boom that has stuffed chatbots into every corner of the tech industry, including coding. That presents clear challenges for a personal coding help forum, as developers get comfortable with AI coding assistance and the very tools that do that are blended into products they use. AI-generated coding answers have also posed problems for the company over the past year. The company issued a temporary ban on users generating answers with the help of an AI chatbot in December last year, but its alleged under-enforcement led to a months-long strike among moderators that was resolved in August; the ban is still in place today. Stack Overflow also announced it would start charging AI companies to train on its site. "

Fake Disney posters prompt Microsoft to reprogram Bing Image Creator | TechSpot - 0 views

    "A hot potato: "Use this picture of my dog to create a realistic poster in the style of Pixar for a movie called Merlin." It's a simple prompt for a generative AI to handle, which actually produces a cute result. Of course, Disney doesn't find it cute at all, which is why Microsoft reprogrammed its Bing Image creator. "

Diary of a TikTok moderator: 'We are the people who sweep up the mess' | TikTok | The G... - 0 views

  •  
    "Next, was two months of probation where we moderated on practice queues that consisted of hundreds of thousands of videos that had already been moderated. The policies we applied to these practice videos were compared with what had previously been applied to them by a more experienced moderator in order to find areas we needed to improve in. Everyone passed their probation. One trend that is particularly hated by moderators are the "recaps". These consist of a 15- to 60-second barrage of pictures, sometimes hundreds, shown as a super fast slideshow often with three to four pictures a second. We have to view every one of these photos for infractions. If a video is 60 seconds long then the system will allocate us around 48 seconds to do this. We also have to check the video description, account bio and hashtags. Around the end of the school year or New Year's Eve, when these sort of videos are popular, it becomes incredibly draining and also affects our stats. "
