AI Unravelled: The false promise of ChatGPT - 0 views

  •  
    "But ChatGPT and similar programs are, by design, unlimited in what they can "learn" (which is to say, memorize); they are incapable of distinguishing the possible from the impossible. Unlike humans, for example, who are endowed with a universal grammar that limits the languages we can learn to those with a certain kind of almost mathematical elegance, these programs learn humanly possible and humanly impossible languages with equal facility. Whereas humans are limited in the kinds of explanations we can rationally conjecture, machine learning systems can learn both that the earth is flat and that the earth is round. They trade merely in probabilities that change over time."

The 'Fingerprinting' Tracking Tool That's Virtually Impossible to Block - 0 views

  •  
    "The type of tracking, called canvas fingerprinting, works by instructing the visitor's web browser to draw a hidden image, and was first documented in a upcoming paper by researchers at Princeton University and KU Leuven University in Belgium. Because each computer draws the image slightly differently, the images can be used to assign each user's device a number that uniquely identifies it."

A dangerous piece of PC ransomware is now impossible to crack - 0 views

  •  
    "TeslaCrypt ransomware with new features that are impossible to crack, according to Cisco's Talos security arm. That means user infected with the latest version (3.01) of the malware can no longer use white hat-engineered software to get their files back. Until someone finds a new solution -- and that seems unlikely -- victims will have to pay."

Google Chrome: Phishing Scam 'Practically Impossible to Spot' | Fortune.com - 0 views

  •  
    "Indeed, this scam is far subtler. It works like this: fraudsters are able to register domains with characters plucked from various alphabets other than the default Latin script. When displayed, it's all but impossible to tell apart a Greek "O" from a Cyrillic "O" from a Latin "O," for instance."

Death by GPS: are satnavs changing our brains? | Technology | The Guardian - 0 views

  •  
    "Anyone who has driven a car through an unfamiliar place can attest to how easy it is to let GPS do all the work. That GPS can have a transformative effect on a society is undeniable. We have come to depend on a technology that, in theory, makes it impossible to get lost. But not only are we still getting lost, we may actually be losing a part of ourselves."

Real life CSI: Google's new AI system unscrambles pixelated faces | Technology | The Gu... - 0 views

  •  
    "Google's neural networks have achieved the dream of CSI viewers everywhere: the company has revealed a new AI system capable of "enhancing" an eight-pixel square image, increasing the resolution 16-fold and effectively restoring lost data. The neural network could be used to increase the resolution of blurred or pixelated faces, in a way previously thought impossible; a similar system was demonstrated for enhancing images of bedrooms, again creating a 32x32 pixel image from an 8x8 one."

Bitcoin fans eye potential in Greek crisis | Technology | The Guardian - 0 views

  •  
    "In theory, when the conventional financial system is experiencing turbulence, alternative currencies such as bitcoin should have their time to shine. The decentralised nature of the currency means that it's impossible for any central bank to impose controls on it, while the pseudonymity at its core could make it the perfect vehicle to get money into and out of the country while avoiding legal reprisals."

MEMS: The micro-machines inside your most beloved technologies - 0 views

  •  
    "MEMS and nanotechnology utilize seemingly impossibly small mechanisms in order to sense, control and respond to a particular environment - these technologies can sense mechanical information as well as biological data. Many MEMS sensors function by detecting small electrical currents that provide data on things such as position, geomagnetic field, acceleration and more, and then pass this information along to other mechanisms within a device or machine.

Science relies on computer modelling, but what happens when it goes wrong? -- Science &... - 0 views

  •  
    Much of current science deals with even more complicated systems, and similarly lacks exact solutions. Such models have to be "computational" - describing how a system changes from one instant to the next. But there is no way to determine the exact state at some time in the future other than by "simulating" its evolution in this way. Weather forecasting is a familiar example; until the advent of computers in the 1950s, it was impossible to predict future weather faster than it actually happened.

Rise of the machines: has technology evolved beyond our control? | Books | The Guardian - 0 views

  •  
    "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"."

'Anonymised' data can never be totally anonymous, says study | Technology | The Guardian - 0 views

  •  
    ""Anonymised" data lies at the core of everything from modern medical research to personalised recommendations and modern AI techniques. Unfortunately, according to a paper, successfully anonymising data is practically impossible for any complex dataset."

Encryption Lava Lamps - San Francisco, California - Atlas Obscura - 1 views

  •  
    "As the lava lamps bubble and swirl, a video camera on the ceiling monitors their unpredictable changes and connects the footage to a computer, which converts the randomness into a virtually unhackable code.  Why use lava lamps for encryption instead of computer-generated code? Since computer codes are created by machines with relatively predictable patterns, it is entirely possible for hackers to guess their algorithms, posing a security risk. Lava lamps, on the other hand, add to the equation the sheer randomness of the physical world, making it nearly impossible for hackers to break through."

The weird world of anti-vax Etsy - 0 views

  •  
    "But the oddest thing happened when you searched the word "trespassing" on Etsy, which feels like the natural place to look for that sort of thing. Lots of the signs high up in the search rankings were strange, word salad, anti-vax signs. They were impossible to ignore or miss. They were everywhere."

Moore's Law: Scientists Just Made a Graphene Transistor Gate the Width of an Atom - 0 views

  •  
    "The gate, a chip component that switches transistors on and off, is a critical measure of transistor size. Previous research had already pushed gate lengths to one nanometer and below. By scaling gate lengths down to the size of single atoms, the latest work sets a new mark that'll be hard to beat. "In the future, it will be almost impossible for people to make a gate length smaller than 0.34 nm," the paper's senior author Tian-Ling Ren told IEEE Spectrum. "This could be the last node for Moore's Law.""

Cracking apps: are crimefighters going too far to bring down cartels? | Organised crime... - 0 views

  •  
    "The Italian supreme court ordered prosecutors last month to disclose how the Sky ECC data had been retrieved, arguing that it was impossible to have a fair trial if the accused is unable to access the evidence or assess its reliability and legality, a position supposed by the NGO Fair Trials. Whether prosecutors choose to do so could determine whether the arrests made this week lead to convictions or not. Prosecutors in the UK face a similar dilemma in relation to the hacking of EncroChat, another secret messaging platform that had the added facility of a "panic" button that when pressed would immediately erase the phone's contents."

What are we worrying about when we worry about TikTok? | Samantha Floreani | The Guardian - 0 views

  •  
    "This is partially why online anonymity is so important - it gives people the grace of exploration and inquiry. It allows people to make choices, change their minds, learn, and grow. TikTok doesn't make room for this kind of internet exploration; it makes it impossible to have curiosity without consequence. TikTok isn't alone in using engagement and recommender algorithms to curate personalised content feeds, but it does take it to the extreme. This is profitable both because it keeps people scrolling and because there's very little difference between being able to personalise content and personalise ads."

ChatGPT maker OpenAI releases 'not fully reliable' tool to detect AI generated content ... - 0 views

  •  
    "Open AI researchers said that while it was "impossible to reliably detect all AI-written text", good classifiers could pick up signs that text was written by AI. The tool could be useful in cases where AI was used for "academic dishonesty" and when AI chatbots were positioned as humans, they said."

TikTok's media literacy crisis: What can be done to stop the spread of misinformation o... - 0 views

  •  
    "The combination of the infinite scroll and lack of live links has led to a very specific kind of information economy on the app. Creators whose brand involves discussing news or popular culture (and there are a lot of them) opt to screenshot headlines, summarize articles, and offer their takes. But it's impossible to know whether the creator even read the article or if they're just offering a summary of the online discourse. Even worse are the accounts that spread false headlines, whether they know it or not. Without live links, all these possible situations are presented to you in the exact same way: with a familiar face on your FYP speaking authoritatively."
