Motherboard – A Major Climate System Will Collapse Decades Ahead of Schedule and Unleash Devastation, Scientists Predict

Jul 262023
 

An important system of currents in the Atlantic Ocean could collapse this century under the pressure of human-driven climate change, triggering “a major tipping element in the climate system” that will have devastating impacts on people and ecosystems, reports a new study.   The new research reveals a far grimmer view of the North Atlantic’s future than the most recent predictions from the Intergovernmental Panel on Climate Change (IPCC) and underscores the urgency of transitioning away from the consumption of fossil fuels to curb the greenhouse gas emissions that are driving warming global temperatures. The Atlantic meridional overturning circulation (AMOC) acts like a huge conveyor belt that delivers warm water from the equator to the poles and…

A recently disclosed bug in many of AMD’s newer consumer, workstation, and server processors can cause the chips to leak data at a rate of up to 30 kilobytes per core per second, writes Tavis Ormandy, a member of Google’s Project Zero security team. Executed properly, the so-called “Zenbleed” vulnerability (CVE-2023-20593) could give attackers access to encryption keys and root and user passwords, along with other sensitive data from any system using a CPU based on AMD’s Zen 2 architecture.
The bug allows attackers to swipe data from a CPU’s registers. Modern processors attempt to speed up operations by guessing what they’ll be asked to do next, called “speculative execution.” But…

Biometric Update – BI2 Technologies’ iris recognition solution offered free to US border sheriffs

Jul 262023
 

Biometrics recognition company BI2 Technologies will give sheriffs in 31 U.S. border counties  free access to its iris biometric-based Mobile Offender Recognition & Information System (MORIS), according to a July 19 statement. The iris recognition software, which works from one meter away and includes liveness detection, scans and processes biometric data using Apple, Android and Microsoft handheld devices. Data is compared to a national offender database. Investments into homeland security are growing. For fiscal 2023, The Department of Homeland Security fiscal 2023 budget is $97.3 billion, up from last year’s $91 billion and 2021’s $87.1 billion budget. Government officials have been gathering iris biometrics since the 2014 pilot of the Next Generation Identification Iris Service,…
