Dark mode toggles: two states are enough • Lea Verou (Light, Dark, System). The core argument is that users only seek out theme toggles when something is wrong — not to preemptively express intent — making the 'System' state irrelevant at the moment of interaction. Tri-state toggles expose the underlying data model rather than aligning with actual user goals, adding cognitive load and UI friction for an extremely rare use case. A well-implemented two-state toggle can still represent all three underlying states: the first click overrides to the opposite of the current resolved value, and the se

BYD says it will have a solid-state car next year, the earliest date anyone has given BYD executive Stella Li claims the company will have a solid-state battery model next year, the earliest date any automaker has cited, though no model, sales plan, or confirmation was given. Toyota targets 2027-2028, Honda and Mercedes around 2030, and LG Energy Solution estimates roughly a decade away for cars. Mercedes and VW's PowerCo are partnered with US-based Factorial Energy, while Taiwan's ProLogium is building a plant in Dunkirk, France. CarNewsChina speculates, via unconfirmed sources, that BYD's ca

Introducing G#: A Go-like language for .NET G# is a new open-source, Go-inspired programming language that compiles to .NET, targeting systems programming and mobile applications while interoperating with existing .NET libraries and NuGet packages. It supports .NET 8 through 10 (10 preferred), offers a VS Code extension with language server support, and blends .NET-style async/await with Go-like fire-and-forget concurrency and channels via an optional extensions package. The language uses packages, funcs, structs and classes, and features like if let and for in for concise null checks and iter
