Introduces a novel method to implement type-safe generic data structures in C using unions to embed compile-time type information.

Outlines four levels of generic programming: macro-based header inclusion, void pointer storage, inline flexible array storage, and union-based type checking with __typeof__.

Demonstrates a union-based List(type) macro that enforces element type safety without runtime overhead.

The game code mistakenly uses an absolute AND $2000 read instead of an immediate AND #$2000.

A new C technical specification (ISO/IEC TS 6010) defines pointer provenance to clarify ambiguous aliasing rules.

Continuous glucose monitors (CGMs) measure blood sugar every few minutes and were once prescription-only but are now available over the counter for about $50.

The sensor is applied using a spring-loaded applicator, takes readings every 5 minutes (transmits every 15), and sticks to the upper arm with adhesive.

The companion app follows strict regulatory guidance, and for iOS can connect to Apple Health, which allows exporting data to XML/CSV.

Let’s Encrypt stopped sending certificate expiration notification emails on June 4, 2025.

Third-party services like Red Sift Certificates Lite are recommended for free expiration monitoring.

The author began charging $100 for 30-minute chats and donating the proceeds to educational nonprofits.

This paid model immediately attracted a wide range of people and raised nearly $6,000.

Charging reduced awkwardness around scheduling time with a stranger and justified social media promotion of the fundraiser.

An ICE test train reached 405.0 km/h on the Erfurt–Leipzig/Halle high-speed line.

The result confirms the line's infrastructure capacity after a decade in operation.

Test runs gathered data on acoustics, aerodynamics, and train-track interactions for future development and maintenance.

The Primary School founded by Priscilla Chan and Mark Zuckerberg in East Palo Alto will close after the 2025-2026 year because the Chan Zuckerberg Initiative is withdrawing funding.

About 400 students from preschool to eighth grade, mostly from low-income families of color, will lose free tuition, health care, and counseling support.
