general-purpose reasoning model in the vein of GPT-5.5

The proof came from a new general-purpose reasoning model, rather than from a system trained specifically for mathematics, scaffolded to search through proof strategies, or targeted at the unit distance problem in particular.

Last, but not least, we have our own extensions to the language. As explained in the previous post on this series, this is code that could be part of the language but, for some reason, it’s not. In the case of PHP we can think, for example, of a DateTime class based on the one provided by PHP but with some extra methods. Another example could be a UUID class, which although not provided by PHP, it is by nature very aseptic, domain agnostic, and therefore could be used by any project independently of the Domain.

This would work if your transaction only wraps a single model's save operation. I need to wrap at least Node + Version + Attachment

Capybara can get us part of the way there. It allows us to work with an API rather than manipulating the HTML directly, but what it provides isn't an application specific API. It gives us low-level API methods like find, fill_in, and click_button, but it doesn't provide us with high-level methods to do things like "sign in to the app" or "click the Dashboard item in the navigation bar".

A Svelte component that monitors an element enters or leaves the viewport/parent element. Performant and efficient thanks to using Intersection Observer under the hood. Can be used in multiple projects including lazy loading images, infinite scrolling, playing/pausing the video when in the viewport, tracking user behaviour firing link pre-fetching and animations and many many more.

It's a generic abstraction for the logic and styling of elements that pop out from the flow of the document and float next to a reference element, overlaid on top of the UI.

Svelte is as general-purpose as they come
