Networking — How Precision Time Protocol handles leap seconds

How Precision Time Protocol handles leap seconds

Systems — Container Queries Unleashed

Container Queries Unleashed

Container queries expand the universe of designs that can be implemented, giving us whole new superpowers. Now that container queries are broadly available, I think it’s time we start exploring this potential! In this post, I’ll share the “killer pattern” I can’t stop using in my work, and explore what’s possible with this new capability.
