Chinese ship spotted lurking over Taiwan-US undersea cables — ‘research vessel’ seen loitering above the 8,000-mile Pacific Light Cable Network fiber-optic system

A new video shows Taiwan’s Coast Guard warning a 200-ft long Chinese-flagged research vessel, spotted loitering over a fiber internet cable, to change course.

Streaming QR codes at 60 FPS achieves nearly 190 KB/s data rate in phone-to-phone tests — browser-based method requires no app, no networking, no pairing, and no permissions beyond camera access

A developer has created a QR code-driven proof-of-concept data transfer system that shuns any dedicated app requirement and neatly sidesteps mandatory networking, pairing, or giving permissions beyond camera access.

Clever hacker fits 537,000 domains in a tiny $5 ESP32 ad-blocking dongle — firmware uses only around 50KB of RAM and can answer blocked lookups in 10 milliseconds
Clever hacker fits 537,000 domains in a tiny $5 ESP32 ad-blocking dongle — firmware uses only around 50KB of RAM and can answer blocked lookups in 10 milliseconds

This project uses a clever hashing trick to fit over half a million blocked domains into just 4MB of flash memory.

Elon Musk’s Starlink releases smaller and lighter V5 residential kit — offers speeds of up to 375 Mbps and almost half the power consumption of V4
Elon Musk’s Starlink releases smaller and lighter V5 residential kit — offers speeds of up to 375 Mbps and almost half the power consumption of V4

Starlink just released a new generation of its Starlink terminal, which reduces its weight by more than 50% and is significantly smaller, too. This should make it easier to install, especially for DIY-ers, but comes with a tiny speed penalty.
