A Better Way to Organize the Internet: Content-Centric Networking

An ambitious new networking scheme promises to make the Internet safer and more reliable

The Internet is more than 45 years old, and it's starting to show its age. To be sure, it has served us wonderfully well. Its underlying technologies delivered the World Wide Web (still a young adult at around 28 years old) and our global communications network. Even as its user base has swelled to 3.4 billion, these technologies have scaled admirably.

Today, however, all of those users demand a level of performance that the Internet was never designed to deliver. The authors of the original Internet protocols, who began their pioneering work in the late 1960s, designed them for a network to be used mainly for sending electronic mail from one computer to another. Now, though, people spend far more time streaming Netflix movies. Oftentimes, one piece of content must be distributed to hundreds of thousands or millions of users simultaneously—and in real time.

When Gamers Get Nasty

Researchers grapple with subjectivity as they develop aIgorithms to detect toxicity in online gaming

Online gaming is a chance for players to come together, socialize and enjoy some friendly competition. Unfortunately, this enjoyable activity can be hindered by abusive language and toxicity, negatively impacting the gaming experience and causing psychological harm. Gendered and racial toxicity, in particular, are all too common in online gaming.

To combat this issue, various groups of researchers have been developing AI models that can detect toxic behavior in real-time as people play. One group recently developed a new model, which is described in a study published May 23 in IEEE Transactions on Games. While the model can detect toxicity with a fair amount of accuracy, its development demonstrates just how challenging it can be to determine what is considered toxic—a subjective matter.

Quantum Computing for Dummies

New guide helps beginners run quantum algorithms on IBM's quantum computers over the cloud

Quantum computers may one day rapidly find solutions to problems no regular computer might ever hope to solve, but there are vanishingly few quantum programmers when compared with the number of conventional programmers in the world. Now a new beginner's guide aims to walk would-be quantum programmers through the implementation of quantum algorithms over the cloud on IBM's publicly available quantum computers.

Whereas classical computers switch transistors either on or off to symbolize data as ones or zeroes, quantum computers use quantum bits, or "qubits," which because of the peculiar nature of quantum physics can exist in a state called superposition where they are both 1 and 0 at the same time. This essentially lets each qubit perform two calculations at once. The more qubits are quantum-mechanically linked, or entangled (see our explainer), within a quantum computer, the greater its computational power can grow, in an exponential fashion.

As 5G evolves into 6G networks, it will be critical that it adopt the most energy-efficient technologies to reduce carbon emissions and our dependence on non-renewable resources.

In terms of increased sustainability, 6G will need to aim directly at lessening its overall environmental impact, including water consumption, raw material sourcing, and waste handling. But it is also important to consider the indirect impact of 6G networks can have on sustainability by conserving resources and minimizing waste in either existing use-cases or novel use-cases.
