Anthropic's Safety Superpower (18 minute read)

Many people think that Anthropic's public statements around its model releases are mostly scare-mongering for the sake of marketing. However, its models are very impressive, and Anthropic's cautious rollout of Mythos was justified. The model is definitely more capable of identifying and exploiting security issues than previous generations. The problem with public releases is that guardrails can be jailbroken, which is what happened shortly after release.

SpaceX & the Sentient Sun (44 minute read)

SpaceX's mission statement to scale to make a sentient sun is more honest than ridiculous. SpaceX is a launch provider with an internet subsidiary and an AI lab.

The golden rule of Customizable Select (5 minute read)

Customizable select, a new feature coming to Safari 27, allows developers to fully control the appearance of 'select' elements without the need for JavaScript libraries or endless 'div' elements. Ensuring this built-in control works well for everyone requires making sure developers always provide text content or accessible text attributes in their 'option' elements. This provides a better UX, better accessibility, and better progressive enhancement.

Websites are increasingly becoming infrastructure for machines. The web will likely still exist in the future, but it may no longer be where people go.
