Hetzner details how its Cloud network stack handles firewalls, DHCP and VXLAN

Hetzner published a technical overview explaining how its VM hosts manage cloud server networking, including public internet access, Private Networks built on VXLAN with unique network identifiers, and a stateful Cloud Firewall enforced directly on the host. It also described the use of DHCP for assigning IPv4 addresses and cloud-init for configuring IPv6, attaching volumes, and pulling metadata from an internal server at 169.254.169.254.

Microsoft and Adobe suspended from H-1B visa program, Vance says

Vice President JD Vance announced Thursday that Microsoft and Adobe have been suspended from participating in the H-1B visa program. The move comes amid accusations that these and other companies have misused the visa system to hire foreign workers at lower wages, and follows broader Trump administration efforts to restrict H-1B visa practices.

MIT Technology Review examines AI refusal tradeoffs and GLP-1 drug side effects

MIT Technology Review's newsletter highlights two stories: one on the difficulty AI systems face in reliably refusing dangerous requests, such as help with pathogens or weapons, and another summarizing emerging research into side effects of GLP-1 weight-loss drugs, including possible links to hair loss, nail disorders and eye nerve damage. The AI piece notes that restricting dangerous capabilities also risks limiting useful applications like cancer research, while giving governments power to set their own boundaries on speech.

Sony reportedly sells 419 VR/AR/XR patents to Meta

According to ZDNet Korea, Sony and Meta signed a Confirmatory Assignment agreement in December 2025 transferring 419 VR, AR, and XR patents developed by Sony between 2010 and 2022.

Researchers propose embedding ethics training directly into engineering coursework

Engineering education researchers are developing two instructional approaches to address a gap in ethics training: one integrates social and ethical issues directly into core technical courses, and another is a standalone course preparing students to act as 'public welfare watchdogs.' They cite survey data showing only about a third of US engineering professionals received training on public welfare responsibilities during their formal education.

Apple set to unveil 'HomePad' smart display at 'Welcome home' event

According to Bloomberg, Apple is preparing to launch its first smart display, dubbed 'HomePad,' combining a 6-inch square screen with HomePod-style speakers in either a round mount or wall-mounted configuration. The device will run a new tvOS-based system called 'homeOS,' controlled primarily via Siri but also supporting touchscreen input, customizable interface elements similar to Apple Watch and StandBy mode, and iPadOS-style apps.

Xona Space Systems to launch first six satellites for commercial GPS rival

Startup Xona Space Systems is set to launch six satellites this month, marking the debut of what it calls the first precision commercial alternative to GPS. Founded in 2019 by five Stanford-trained engineers, the company aims to sell more accurate, harder-to-jam positioning and timing signals than government-run systems like GPS, Galileo, BeiDou and GLONASS. CEO Brian Manning said the company built a new satellite architecture that avoids costly onboard atomic clocks by relying on close ground communication.
