The startup is one of many entering the RV space, but it's banking on a hybrid power system that can go far beyond campsites.

Donut Lab's solid-state battery claims have been thoroughly debunked by Ryan Inis Hughes on his popular Ziroth YouTube channel. According to Hughes, Donut Lab has engaged in deliberate, calculated deception by claiming to have a solid-state battery ready for mass production. In reality, it's nothing more than a standard lithium-ion design. Hughes' investigation got an […]

Waymo has acquired a massive 5,500-acre proving ground in Arizona owned by Route 14 Investment Partners LLC, a Delaware shell company associated with Apple, according to documents filed with Maricopa County.

I've said one and mean another, and I've used one when I needed another. Please bear with me as I note the similarities and differences between scroll-driven animations, scroll-triggered animations, container query scroll states, and view transitions for my future self. Scroll-Driven, Scroll-Triggered, Scroll States, and View Transitions originally handwritten and published with love on CSS-Tricks . You should really get the newsletter as well.

Uber is getting ready to put robotaxis on London's streets, opening an interest list for riders who want to be among the first to hail one of Wayve's autonomous vehicles when the service goes live later this year. The rollout would be a milestone in one of Uber's biggest markets and an early test of […]

Uber customers in the UK can now join an interest list to increase their chances of being matched with a Wayve robotaxi.

Martin Kleppmann discusses the urgent need for technological sovereignty in modern infrastructure. Exploring the shifting landscape of global tech dependencies, he shares how engineering leaders can leverage multi-cloud architecture, de facto API standardization, the AT Protocol, and local-first development paradigms to reclaim user agency and build highly resilient systems.
