FCC Warns Pittsburgh Amateur Radio Operator for 911 Interference
- The Federal Communications Commission has sent a notice of licensed operation and harmful interference to an amateur radio operator in Pittsburgh regarding transmissions on a 911 emergency services channel from a handheld transceiver. Last summer, the FCC received a complaint from Allegheny County, Pa., Emergency Services concerning interference with one of its UHF “T-Band” emergency communications channels. The interference affected the county’s west EMS dispatch channel on 470.4375 MHz. After the agents notified Kundston of the issue, he produced a Baofeng BTech UV-Pro handheld radio.

Local privilege escalation in snapd
- CVE-2026-3888 - Local privilege escalation in snapd on Linux allows local attackers to get root privilege by re-creating snap’s private /tmp directory when systemd-tmpfiles is configured to automatically clean up this directory. This issue affects Ubuntu 16.04 LTS, 18.04 LTS, 20.04 LTS, 22.04 LTS, and 24.04 LTS.

YOLO Linux
- YOLO Linux is a modern Linux distribution designed from first principles to prioritize user outcomes over system management, featuring a conversational AI agent that replaces the traditional command line. Instead of requiring users to memorize commands or configure complex settings, YOLO Linux allows them to describe their intent in plain language (e.g., “Install the browser” or “Connect to the VPN”), and the AI agent automatically handles the installation, configuration, and security. Built on a standard Linux 6.12 kernel, it maintains a zero-shell security posture by eliminating direct user access to the terminal, thereby reducing the attack surface while ensuring all operations are logged, auditable, and explainable. This approach aims to make Linux accessible to everyone by removing the learning curve associated with traditional operating system administration.
