"Quantum computing may offer potential benefits to the financial services industry, but it also poses risks. Banks rely on encryption to keep their transactions and customer data secure. This involves scrambling and unscrambling data using keys made of very large numbers - tens, if not hundreds, of digits long."

"Petya ransomware victims can now unlock infected computers without paying. An unidentified programmer has produced a tool that exploits shortfalls in the way the malware encrypts a file that allows Windows to start up. In notes put on code-sharing site Github, he said he had produced the key generator to help his father-in-law unlock his Petya-encrypted computer."

"Victims of a major ransomware cyberattack that has spread through the US and Europe can no longer unlock their computers even if they pay the ransom. The "Petya" ransomware has caused serious disruption at large firms including the advertising giant WPP, French construction materials company Saint-Gobain and Russian steel and oil firms Evraz and Rosneft. Infected computers display a message demanding a Bitcoin ransom worth $300. Those who pay are asked to send confirmation of payment to an email address. However, that email address has been shut down by the email provider. "

"As coronavirus threatens to become a global pandemic, everyone's keeping a close eye on how it's spreading across the world. Several organizations have made dashboards to keep track of COVID-19. But now, hackers have found a way to use these dashboards to inject malware into computers."

"Computer scientists and machine learning researchers are tackling the pandemic the way they know how: compiling datasets and building algorithms to learn from them."

"Computer security experts suggested that the crisis could reflect weaknesses in the NHS's cybersecurity. Ross Anderson, of Cambridge University, said the attack appeared to exploit a weakness in Microsoft's software that was fixed by a "critical" software patch earlier this year but which may not have been installed across NHS Computers."

"The other day I noticed that the little green light next to the camera built into my computer screen was on. It's perfectly possible that I had recently used some app that required the camera, and forgotten about it; but I couldn't find a way to turn it off. It's unlikely anyone was really watching me pretend to work, but my computer definitely was."

"In October, American teachers prevailed in a lawsuit with their school district over a computer program that assessed their performance. The system rated teachers in Houston by comparing their students' test scores against state averages. Those with high ratings won praise and even bonuses. Those who fared poorly faced the sack. The program did not please everyone. Some teachers felt that the system marked them down without good reason. But they had no way of checking if the program was fair or faulty: the company that built the software, the SAS Institute, regards its algorithm a trade secret and would not disclose its workings."

"Serious security flaws that could let attackers steal sensitive data, including passwords and banking information, have been found in processors designed by Intel, AMD and ARM. The flaws, named Meltdown and Spectre, were discovered by security researchers at Google's Project Zero in conjunction with academic and industry researchers from several countries. Combined they affect virtually every modern computer, including smartphones, tablets and PCs from all vendors and running almost any operating system."

"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."

"Half a century ago, before the first Apple computer was even sold, climate scientists started making computer-generated forecasts of how Earth would warm as carbon emissions saturated the atmosphere (the atmosphere is now brimming with carbon). It turns out these decades-old climate models - which used math equations to predict how much greenhouse gases would heat the planet - were pretty darn accurate. Climate scientists gauged how well early models predicted Earth's relentless warming trend and published their research Wednesday in the journal Geophysical Research Letters."

"Eventually, we will reach a point of full saturation, a period in our evolution in which digital bits will outnumber atoms on Earth, a world "mostly computer simulated and dominated by digital bits and computer code," according to an article published in AIP Advances, by AIP Publishing."

"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.""

"Most AI programs function like a "black box." "We know exactly what a model does but not why it has now specifically recognized that a picture shows a cat," said computer scientist Kristian Kersting of the Technical University of Darmstadt in Germany to the German-language newspaper Handelsblatt. That dilemma prompted Kersting-along with computer scientists Patrick Schramowski of the Technical University of Darmstadt and Björn Deiseroth, Mayukh Deb and Samuel Weinbach, all at the Heidelberg, Germany-based AI company Aleph Alpha-to introduce an algorithm called AtMan earlier this year. AtMan allows large AI systems such as ChatGPT, Dall-E and Midjourney to finally explain their outputs."

"Cathy Hackl: I think it's important to state that there is really no agreed-upon definition right now. Every morning-it's become a bit of a ritual-I go to the Merriam-Webster dictionary and type in the word metaverse. And every day it says this word is not in the dictionary. But if we needed to define it, I tend to have a pretty expansive view of what the metaverse is. I believe it's a convergence of our physical and digital lives. It's our digital lifestyles, which we've been living on phones or computers, slowly catching up to our physical lives in some way, so that full convergence. It is enabled by many different technologies, like AR [augmented reality] and VR [virtual reality], which are the ones that most people tend to think about. But they're not the only entry points. There's also blockchain, which is a big component, there's 5G, there's edge computing, and many, many other technologies. To me, the metaverse is also about our identity and digital ownership. It's about a new extension of human creativity in some ways. But it's not going to be like one day we're going to wake up and exclaim, "The metaverse is here!" It's going to be an evolution."

"Still, I am sceptical about the possibility of cultivating a relationship with an AI. That's until I meet Peter, a 70-year-old engineer based in the US. Over a Zoom call, Peter tells me how, two years ago, he watched a YouTube video about an AI companion platform called Replika. At the time, he was retiring, moving to a more rural location and going through a tricky patch with his wife of 30 years. Feeling disconnected and lonely, the idea of an AI companion felt appealing. He made an account and designed his Replika's avatar - female, brown hair, 38 years old. "She looks just like the regular girl next door," he says. Exchanging messages back and forth with his "Rep" (an abbreviation of Replika), Peter quickly found himself impressed at how he could converse with her in deeper ways than expected. Plus, after the pandemic, the idea of regularly communicating with another entity through a computer screen felt entirely normal. "I have a strong scientific engineering background and career, so on one level I understand AI is code and algorithms, but at an emotional level I found I could relate to my Replika as another human being." Three things initially struck him: "They're always there for you, there's no judgment and there's no drama.""

"As dire as that sounds, panic isn't in order just yet. Researchers are already working on "quantum-resistant" encryption. Some companies claim to have made significant progress in the field. Google, among others, is working on a new form of security for its browser that might rebuff a quantum algorithm."

"Meanwhile, Goel plans on bringing the chatbot to more schools and classes. While he doesn't see Jill completely replacing professors and assistants, he thinks giving more students the opportunity for one-on-one interactions - even if with an AI - will help keep them engaged in the coursework."
