The core idea behind the Bitcoin system is to make all the participants in the system, collectively, the bank. To do this, blockchains are used. Blockchains are distributed, tamper-proof ledgers, which can record every transaction made within a network.
The explosive popularity of YOLO has led to warnings of the same problem that led to Yik Yak’s shutdown, namely that its anonymity could lead to cyberbullying and hate speech. But in an age of online surveillance and self-censorship, proponents view anonymity as an essential component of privacy and free-speech. And our own research on anonymous online interactions among teenagers in the UK and Ireland has revealed a wider range of interactions that extend beyond the toxic to the benign and even beneficial.
Despite their names, artificial intelligence technologies and their component systems, such as artificial neural networks, don’t have much to do with real brain science. I’m a professor of bioengineering and neurosciences interested in understanding how the brain works as a system – and how we can use that knowledge to design and engineer new machine learning models.
These days all text is digital. From writing an email to publishing a new edition of War and Peace, text nearly always exists on a computer first. Yet there are writers who take full advantage of the computer’s possibilities, utilising new technologies to broach complex subject matter. Electronic or digital literature does not refer to e-books, but to works that depend on electronic “code” to exist. Put simply, you can print an e-book, but you cannot print electronic literature. Within the field there is emphasis on experimentation. Many works are the result of authors simply trying new things out and seeing what…
It’s more likely that blockchain, and even Libra, is a means to a end; Calibra is about Facebook wanting to be not only the world’s biggest social media platform but also the globe’s go-to marketplace, putting Amazon, eBay, Apple and Google in the shade.
Gestures and emoji don’t break down into smaller parts. Nor do they easily combine into larger words or sentences (unless we’re using a clunky version of the grammar of our language).
NASA’s Apollo programme was one of the most challenging technological achievements in the 20th century. Beyond the space race and exploration, it contributed to several inventions and innovations that are still having an impact on our lives. But at the same time, there are several myths regarding what technologies actually came out of it.
If you’ve ever participated in a virtual reality (VR) experience, you might have found yourself navigating the virtual world as an avatar. If you haven’t, you probably recognise the experience from its portrayal in film and on television. Popular media has brought us characters like Jake Sully in Avatar, Wade Watts in Ready Player One, and Danny and Karl in the Black Mirror episode Striking Vipers. In these examples, the character’s virtual alter-ego is physically different from who they are in the real world. The connection between the real person and their virtual avatar is called “embodiment”. If you have a strong sense…
As a cryptocurrency, there is no physical form that gives Bitcoin value, so it is impossible to perform traditional fundamental analysis of the currency. Consequently, many investors track the so-called technical trading indicators (geometric patterns constructed from historical prices and trading volumes) in order to understand and predict Bitcoin’s future movement.
This year marks the 50th anniversary of the first Apollo moon landing. This was possible thanks to an extraordinary acceleration of space technology. Within a remarkably short period of time leading up to the event, engineers had mastered rocket propulsion, on-board computing and space operations, partially thanks to an essentially unlimited budget. Since the days of these heroic endeavours, space engineering has matured into a series of interconnected technologies that deliver exciting new space science missions, a fire hose of Earth observation data and a network of global communication and navigation services. We can now land probes on comets and glimpse further back in…
