Re:Seeing Around Corners Using Smartphone-Grade Lidar on Thursday May 28, 2026 @01:26PM (#48312371)
Ordinary WiFi can "see" through walls/corners with biometric fingerprinting of humans, https://gizmodo.com/researchers-issue-warning-about-tech-tha...

  Researchers collected WiFi signal recordings from nearly 200 participants as they walked through a WiFi field using different walking styles. The data was recorded from four different perspectives using both the BFI method and an older WiFi sensing approach relying on channel state information, or CSI. 

  “This technology turns every router into a potential means for surveillance,” said co-author Julian Todt in the press release. “If you regularly pass by a café that operates a WiFi network, you could be identified there without noticing it and be recognized later – for example by public authorities or companies.”

  The researchers are urging the IEEE, the organization that sets industry standards, to include stronger privacy safeguards in the upcoming 802.11bf standard, which is meant to standardize WiFi sensing applications.
Re:Bringing Chrome to ARM64 Linux Devices on Thursday March 12, 2026 @07:05PM (#47358480)

  Google will launch Chrome for ARM64 Linux devices in Q2 2026, following the successful expansion of Chrome to Arm-powered macOS devices in 2020 and Arm-powered Windows devices in 2024.. Google is partnering with NVIDIA to make it easier for DGX Spark users to install Chrome. 
Will be useful in isolated Debian Linux pKVM Arm VM with accelerated vGPU, in Android-ChromeOS converged desktop on Qualcomm Arm laptops. Possibly Nvidia-Mediatek Arm laptops, if they support h/w nested virt for pKVM/AVF.

> Researchers in Italy have developed a way to create a biometric identifier for people based on the way the human body interferes with Wi-Fi signal propagation.. can re-identify a person in other locations most of the time when a Wi-Fi signal can be measured. Observers could therefore track a person as they pass through signals sent by different Wi-Fi networks – even if they’re not carrying a phone.. their technique makes accurate matches on the public NTU-Fi dataset up to 95.5 percent.

WiFi Sensing is part of Wi-Fi 7 and present in most recent laptops and smartphones. Local NPU machine learning can be combined with WiFI radar. Malware can attack phone and radio basebands and exploit this capability. It can uniquely fingerprint human biometrics, measure breathing rate, record keystrokes and more. Thousands of academic papers have been published in the last 15 years on "device free wireless sensing", before the capability was ratified by IEEE as 802.11bf. It's being rolled out commercially. Mitigations include drywall or insulation with a layer of RF shielding.
