In 1983, the BBC aired a six-part series called Fun to Imagine with a simple premise: put physicist Richard Feynman in front of a camera and have him explain everyday things. In this clip from one of the episodes, Feynman explains in very simple terms what fire is:
So good. Watch the whole thing…it seems like you get the gist about 2 minutes in, but that’s only half the story. See also Feynman explaining rubber bands, how trains go around curves, and how magnets work.

While Sonnet 4.5 remains the default [in Claude Code], Haiku 4.5 now powers the Explore subagent which can rapidly gather context on your codebase to build apps even faster.
You can select Haiku 4.5 to be your default model in /model. When selected, you’ll automatically use Sonnet 4.5 in Plan mode and Haiku 4.5 for execution for smarter plans and faster results.

Previous system cards have reported results on an expanded version of our earlier agentic misalignment evaluation suite: three families of exotic scenarios meant to elicit the model to commit blackmail, attempt a murder, and frame someone for financial crimes. We choose not to report full results here because, similarly to Claude Sonnet 4.5, Claude Haiku 4.5 showed many clear examples of verbalized evaluation awareness on all three of the scenarios tested in this suite. Since the suite only consisted of many similar variants of three core scenarios, we expect that the model maintained high unverbalized awareness across the board, and we do not trust it to be representative of behavior in the real extreme situations the suite is meant to emulate.

Halo Fund:
Halo Fund, a new $1 billion growth fund founded by Ryan Smith and Ryan Sweeney, today announced a strategic secondary investment in 1Password, a leader in identity security and pioneer of Extended Access Management. Halo Fund is joined in this investment by legendary technology leaders, including Flume Ventures with Sun Microsystems founder Scott McNealy and former Zscaler Chief Strategy Officer Manoj Apte. This transaction underscores strong demand from innovators and investors to join 1Password’s journey.
Well I’m sure this will halt 1Password’s descent into enterprise/cross-platform shittiness.

Adam Engst, at TidBITS:
Apple’s new Liquid Glass interface design brings transparency and blur effects to all Apple operating systems, but many users find it distracting or difficult to read. Here’s how to control its effects and make your interface more usable. Although the relevant Accessibility settings are quite similar across macOS, iOS, watchOS, and tvOS, I separate them because they offer different levels of utility in each.
Comprehensive, illustrated overview of the various Accessibility settings (and, on MacOS 26 Tahoe, hidden command-line defaults settings) that let you adjust the transparency and contrast of Liquid Glass across the various Apple OS 26 interfaces. A useful guide for today — and, I bet, a useful look back at the first versions of Liquid Glass for the future.

“The spread of dangerous infections that do not respond to antibiotics has been increasing by as much as 15 percent a year”, says the WHO. “The less people have access to quality care, the more they’re likely to suffer from drug-resistant infection.”
