  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.

  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.

> 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.

Is this independent of the Linux Security Modules policy, e.g. RHEL default policy for SE Linux?

The arrows of time branch and spiral, so it's possible that "later" could require some properties of "earlier".

If Photon could not be open-sourced, it could be licensed to a third party for custodian maintenance. If QNX is abandoning Photon forever, would Blackberry object to Photon being cloned for Linux or FreeBSD? That could preserve a future option for QNX to use it again, like XFCE.

Enthusiasts still use Blackberry keyboards on handheld devices in 2025, which sell out in minutes. In a parallel universe, Blackberry.com offers embedded SBC developers self-service purchase and global delivery of the legendary Blackberry keyboard, with Bluetooth for convenience or USB-c for security.

Compiled cobalt with liquid-rust on iSH is fast enough for static blog publishing and browser-based offline site preview on iOS/iPadOS, https://news.ycombinator.com/item?id=46220227

Due to lack of JIT on iOS, Jekyll is too slow to run on iSH. Liquid-Rust (https://github.com/cobalt-org/liquid-rust) templates, even with partial compatibility for the Ruby-based Liquid template engine, reduce the cost of migrating from the Jekyll Ruby static site generator used by Github Pages.

On Debian x86, build a cobalt static binary for use on iSH (Alpine Linux /w musl libc) on iPadOS:

  sudo apt install rustup build-essential
  rustup target add i586-unknown-linux-musl
  git clone https://github.com/cobalt-org/cobalt.rs
  cd cobalt.rs
  cargo build --release --target i586-unknown-linux-musl
  cp target/i586-unknown-linux-musl/release/cobalt /mnt/usb

  ./cobalt --no-watch --host 0.0.0.0 --port NNNN

  SARLink is a passive satellite backscatter communication system that uses existing spaceborne synthetic aperture radar (SAR) imaging satellites to provide connectivity in remote regions .. As the first technique for passively sending information bits from the ground to a SAR satellite — and with some SAR systems offering open-access data — this system could enable anyone to send information without expensive licenses or subscriptions. 

  Thus, it provides an accessible way of sending messages in areas without connectivity or in censored environments where active radio transmissions cannot be used. Furthermore, SARLink requires no modification of the satellite infrastructure.. We demonstrate our system using the European Space Agency (ESA) satellite Sentinel-1A, as the data is freely available and the system regularly images all the land on Earth .. a 5.5 ft by 5.5 ft modulating corner reflector could send 60 bits every satellite pass, enough to support low bandwidth sensor data and messages.

Arm RK3399 SoC is blob free and some (Pinephone Pro, N4S, Chrome tablet) devices are small enough for sidecar usage.

Once KB/mouse emulation exists, it can be integrated with Linux window manager to treat a tablet/phone as external "display", e.g. move Linux mouse pointer to the right edge of laptop display, push to the right with a bit of physics delay, then activate kb/mouse emulation and send all keystrokes and mouse movements over USB-c cable to the external device.

This would avoid the travel weight cost of a dedicated keyboard for tablet or phone.

Linux has FUSE read-only support for decrypting APFS. iOS can read/write encrypted APFS that is formatted on macOS.

Would be nice to have encrypted ZFS support on multiple platforms, including iOS and Android.
