The Federal Communications Commission (FCC) has announced a record-breaking $299,997,000 fine imposed on an international network of companies for placing five billion robocalls to more than 500 million phone numbers over three months in 2021.

The fined companies operated as Sumco Panama, Virtual Telecom, Davis Telecom, Geist Telecom, Fugle Telecom, Tech Direct, Mobi Telecom, and Posting Express.

“The enterprise violated a multitude of robocall prohibitions by making pre-recorded voice calls to mobile phones without prior express consent, placing telemarketing calls without written consent, dialing numbers included on the National Do Not Call Registry, failing to identify the caller at the start of the message, and failing to provide a call-back number that allowed consumers to opt out of future calls,” explained the FCC press release.

Dumbphones seem to be making a return.

Rechargeable lithium-ion batteries power smartphones, electric vehicles and storage for solar and wind energy, among other technologies.

They descend from another technology, the lithium-metal battery, that hasn’t been developed or adopted as broadly. There’s a reason for that: While lithium-metal batteries have the potential to hold about double the energy that lithium-ion batteries can, they also present a far greater risk of catching fire or even exploding.

Now, a study by members of the California NanoSystems Institute at UCLA reveals a fundamental discovery that could lead to safer lithium-metal batteries that outperform today’s lithium-ion batteries. The research was published today in the journal Nature.

Introduction to george hotz and connor leahy.

The debate opens with introductions to the two featured guests — George Hotz and Connor Leahy. Hotz is described as a maverick hacker known for daring technical exploits like jailbreaking the iPhone. His hacker skills are likened to the technical finesse of Elon Musk combined with the wit of Tony Stark. Leahy is introduced as a steadfast defender of AI safety, determined to safeguard humanity from potential threats posed by artificial intelligence. His goal is to “break the damning prophecy and render us super saved.”

George hotz’s opening statement: intelligence and power.

In the shade of a coconut palm, Chandrika tilts her smartphone screen to avoid the sun’s glare. It is early morning in Alahalli village in the southern Indian state of Karnataka, but the heat and humidity are rising fast. As Chandrika scrolls, she clicks on several audio clips in succession, demonstrating the simplicity of the app she recently started using. At each tap, the sound of her voice speaking her mother tongue emerges from the phone.

Before she started using this app, 30-year-old Chandrika (who, like many South Indians, uses the first letter of her father’s name, K., instead of a last name) had just 184 rupees ($2.25) in her bank account. But in return for around six hours of work spread over several days in late April, she received 2,570 rupees ($31.30). That’s roughly the same amount she makes in a month of working as a teacher at a distant school, after the cost of the three buses it takes her to get there and back. Unlike her day job, the app doesn’t make her wait until the end of the month for payment; money lands in her bank account in just a few hours. Just by reading text aloud in her native language of Kannada, spoken by around 60 million people mostly in central and southern India, Chandrika has used this app to earn an hourly wage of about $5, nearly 20 times the Indian minimum. And in a few days, more money will arrive—a 50% bonus, awarded once the voice clips are validated as accurate.

Organic light-emitting diodes (OLEDs) are now widely used. For use in displays, blue OLEDs are additionally required to supplement the primary colors red and green. Especially in blue OLEDs, impurities give rise to strong electrical losses, which could be partly circumvented by using highly complex and expensive device layouts. A team from the Max Planck Institute for Polymer Research has now developed a new material concept that potentially allows efficient blue OLEDs with a strongly simplified structure.

From televisions to smartphones: organic light-emitting diodes (OLEDs) are nowadays finding their way into many devices that we use every day. To display an image, they are needed in the three primary colors red, green and blue. In particular, light-emitting diodes for blue light are still difficult to manufacture because blue light—physically spoken—has a high energy, which makes the development of materials difficult.

Especially the presence of minute quantities of impurities in the material that cannot be removed plays a decisive role in the performance of these materials. These impurities— oxygen molecules, for example—form obstacles for electrons to move inside the diode and participate in the light-generation process. When an electron is captured by such an obstacle, its energy is not converted into light but into heat. This problem, known as “charge trapping”, occurs primarily in blue OLEDs and significantly reduces their efficiency.

Cities can be obstacle courses for communications signals. A radio signal must travel from a cell phone to a router to a cell tower, and onward to its recipient—all while bouncing between walls, buildings and other structures. When it hits an obstacle, the radio wave gets scattered, diminishing the signal. This in turn reduces the bandwidth. At the same time, the signal must compete with the bandwidth needs of numerous other devices in the area. All this reduces the amount of information the signal can communicate.

Newly developed small, lightweight reflective surfaces could revolutionize communications in crowded environments by providing unprecedented control over electromagnetic signals, like radio waves.

Historically, engineers have used repeaters—electronic devices that receive a signal and retransmit it—to help these communications signals cover longer distances and get around obstacles, but this technology is reaching its limits. Now, engineers are looking to modify the behavior of the communications signal itself. Enter reconfigurable intelligent surfaces (RIS).

Apple has rolled out security updates to iOS, iPadOS, macOS, tvOS, watchOS, and Safari to address several security vulnerabilities, including one actively exploited zero-day bug in the wild.

Tracked as CVE-2023–38606, the shortcoming resides in the kernel and permits a malicious app to modify sensitive kernel state potentially. The company said it was addressed with improved state management.

“Apple is aware of a report that this issue may have been actively exploited against versions of iOS released before iOS 15.7.1,” the tech giant noted in its advisory.
