"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."

"Malwarebytes points to desktop app whose EULA includes clause getting you to agree to Bitcoin mining - from which you won't benefit"

"Fear of data-mining of healthcare could be costing as many as 100,000 lives a year, according to Google's Larry Page. Speaking out in response to fears over his company's vast haul of personal information, Page made the case that not only is Google not going too far with collecting and analysing such information - it's not going far enough."

"The NSA has a tool that records and analyzes all the flow of data that the spy agency collects around the world. Think of it as a global data-mining software that details exactly how much intelligence, and of what type, has been collected from every country in the world. It's aptly called "Boundless Informant." "

"Taken as a whole, the information Google collects about users is shockingly complete. The company can mine your emails and Drive documents, track your browsing history, track the videos you watch on YouTube, obtain your WiFi passwords and much more."

"But the bigger problem with things like public tweets is that no-one knows what information can be derived from them, either now or in the future. I write as a data analyst who's done a fair bit of work with this kind of material. What follows are a few techniques that aren't at all obvious to the average Twitter user. They go far beyond reading the surface text (or metadata) of an individual tweet. And these are just some of the techniques currently used to mine this data, ethically or unethically, legally or illegally."

"Researchers are becoming so adept at mining information from genealogical, medical and police genetic databases that it is becoming difficult to protect anyone's privacy-even those who have never submitted their DNA for analysis."

"That's interesting work suggesting that Russian troll activity was significantly more ambitious on an international scale than previously thought. It also suggests a way of spotting this kind of meddling as it is happening by looking for the kind of forensic fingerprint the team identified. Of course, finding trolls is a cat-and-mouse game. For the organizations responsible for Russian troll activity, it ought to be a straightforward matter to change the pattern of activity in a way that does not create the same signature."

""I don't really care about data privacy because I think it's all an illusion anyway." It's interesting to see how this encounter also reflects the general behavior of a majority of people when it comes to privacy. Although user data has long been a gold mine for companies, would it be more acceptable if they started paying their users in exchange for it?"

"It has led to a proliferation of fake news and clickbait. It has fuelled surveillance capitalism and normalised pervasive tracking and data-mining. If we want to do something about the proliferation of misinformation and erosion of trust in traditional institutions, it is not enough to regulate or factcheck political adverts. We need to crack down on the use of personal information for all targeted advertising. Otherwise democracy will continue to erode, one highly optimised click at a time."

"Our social media platforms are powered by a surveillance-based business model designed to mine, manipulate, and extract our human experiences at any cost, causing a breakdown of our information ecosystem and shared sense of truth worldwide. This extractive business model is not built for us but built to exploit us."

"In 2014, Facebook bought WhatsApp for $19b, and promised users that it wouldn't harvest their data and mix it with the surveillance troves it got from Facebook and Instagram. It lied. Years later, Facebook mixes data from all of its properties, mining it for data that ultimately helps advertisers, political campaigns and fraudsters find prospects for whatever they're peddling. Today, Facebook is in the process of acquiring Giphy, and while Giphy currently doesn't track users when they embed GIFs in messages, Facebook could start doing that anytime"

"These are the early days of the data revolution in personal decision-making. I am not claiming that we can completely outsource our lifestyle choices to algorithms, though we might get to that point in the future. I am claiming instead that we can all dramatically improve our decision-making by consulting evidence mined from thousands or millions of people who faced dilemmas similar to ours. And we can do that now."

"Everyone in the cryptocurrency world has heard of Satoshi Nakamoto, the mysterious inventor of Bitcoin. But not many have heard of Peter Bushnell, the not-so-mysterious inventor of Feathercoin. On 20 April, he announced his alternative currency to a gaggle of online followers. One month later, nearly 7m of them have been mined"

"Insurance is just one area which could benefit from mining patient information in order to acquire the best business outcomes - although at the detriment of the person attempting to get insurance. After all, why would a company agree to hand out a policy to a person whose data suggests has a high risk of a heart attack?"

"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."

"As Zuckerberg surely knows, providing a greater sense of control over their personal data won't make Facebook users more cautious. It will instead encourage them to share more. This, of course, will produce more data for Facebook to mine to its own financial advantage."

"Hangzhou Zhongheng Electric is just one example of the large-scale application of brain surveillance devices to monitor people's emotions and other mental activities in the workplace, according to scientists and companies involved in the government-backed projects. Concealed in regular safety helmets or uniform hats, these lightweight, wireless sensors constantly monitor the wearer's brainwaves and stream the data to computers that use artificial intelligence algorithms to detect emotional spikes such as depression, anxiety or rage."
