The new Nvidia GeForce RTX 3090 is a gaming powerhouse, but that’s not all it can do. According to the makers of a popular password recovery application, the RTX 3090 is also good at brute-forcing passwords. That’s great if you forget an important password, but that’s probably not why people are using such tools. The latest Nvidia cards could make cracking someone else’s files almost trivially easy.

The RTX 3090 is Nvidia’s latest top-of-the-line GPU with a GA102 graphics processor sporting 10,496 cores and 24GB of GDDR6X memory. It is monstrously, obscenely powerful by today’s gaming standards, and comes with a correspondingly high price of $1,500, give or take a few hundred depending on supply. With a focus on high core counts, GPUs are also great for parallel computing. That’s why you couldn’t even buy a GPU for several months when Bitcoin was at its peak. In the same vein, GPUs are very good at cracking passwords.

Researchers from Trinity have discovered a uniquely quantum effect in erasing information that may have significant implications for the design of quantum computing chips. Their surprising discovery brings back to life the paradoxical “Maxwell’s demon,” which has tormented physicists for over 150 years.

The thermodynamics of computation was brought to the fore in 1961 when Rolf Landauer, then at IBM, discovered a relationship between the dissipation of heat and logically irreversible operations. Landauer is known for the mantra “Information is Physical,” which reminds us that information is not abstract and is encoded on physical hardware.

The “bit” is the currency of information (it can be either zero or one) and Landauer discovered that when a bit is erased there is a minimum amount of heat released. This is known as Landauer’s bound and is the definitive link between information theory and thermodynamics.

Negotiations are a central part of many human interactions, ranging from business discussions and legal proceedings to conversations with vendors at local markets. Researchers specialized in economics, psychology, and more recently, computer science have conducted several studies aimed at better understanding how humans negotiate with one another in the hope of shedding light on some of the dynamics of human decision-making and enabling the development of machines that can replicate these dynamics.

A research team at the University of Southern California has been exploring the possibility of building automated systems that can negotiate with humans. In a paper pre-published on arXiv and set to be presented at the IJCAI conference, they presented a virtual agent based on a framework called IAGO (Interactive Arbitration Guide Online), which can negotiate with humans in a three-round negotiation task. This virtual agent, called Pilot, is one of the finalists of the IJCAI conference’s global negotiation challenge (ANAC).

“Recently, researchers realized the potential applications of building automated systems that can negotiate with humans,” Kushal Chawla, one of the researchers who carried out the study, told TechXplore. “These intelligent assistants can be really useful to augment current techniques for training people to have stronger social skills. Examples include teaching business students to negotiate for successful deals or lawyers to accurately assess settlement rates in legal proceedings.”

Brain–computer interfaces enable active communication and execution of a pre-defined set of commands, such as typing a letter or moving a cursor. However, they have thus far not been able to infer more complex intentions or adapt more complex output based on brain signals. Here, we present neuroadaptive generative modelling, which uses a participant’s brain signals as feedback to adapt a boundless generative model and generate new information matching the participant’s intentions. We report an experiment validating the paradigm in generating images of human faces. In the experiment, participants were asked to specifically focus on perceptual categories, such as old or young people, while being presented with computer-generated, photorealistic faces with varying visual features. Their EEG signals associated with the images were then used as a feedback signal to update a model of the user’s intentions, from which new images were generated using a generative adversarial network. A double-blind follow-up with the participant evaluating the output shows that neuroadaptive modelling can be utilised to produce images matching the perceptual category features. The approach demonstrates brain-based creative augmentation between computers and humans for producing new information matching the human operator’s perceptual categories.

After 44 years, there’s finally a better way to find approximate solutions to the notoriously difficult traveling salesperson problem.

“Our goal was to integrate interactive functionalities directly into the fibers of textiles instead of just attaching electronic components to them,” says Jürgen Steimle, computer science professor at Saarland University. In his research group on human-computer interaction at Saarland Informatics Campus, he and his colleagues are investigating how computers and their operation can be integrated as seamlessly as possible into the physical world. This includes the use of electro-interactive materials.

Previous approaches to the production of these textiles are complicated and influence the haptics of the material. The new method makes it possible to convert textiles and garments into e-textiles, without affecting their original properties—they remain thin, stretchable and supple. This creates new options for quick and versatile experimentation with new forms of e-textiles and their integration into IT devices.

“Especially for devices worn on the body, it is important that they restrict movement as little as possible and at the same time can process high-resolution input signals”, explains Paul Strohmeier, one of the initiators of the project and a scientist in Steimle’s research group. To achieve this, the Saarbrücken researchers are using the in-situ polymerization process. Here, the electrical properties are “dyed” into the fabric: a textile is subjected to a chemical reaction in a water bath, known as polymerization, which makes it electrically conductive and sensitive to pressure and stretching, giving it so-called piezoresistive properties. By “dyeing” only certain areas of a textile or polymerizing individual threads, the computer scientists can produce customized e-textiles.
