I recently learnt that one can download WOFF files from any website that uses them, and convert them into TTF files (using an online tool like CloudConvert) if we wanted to use them in say a MS Word or Powerpoint slide deck.
This allowed me to create a custom powerpoint theme / template that captures the essence of a particular brand.
Worth noting that web fonts are often split up across multiple files for sets of codepoints and font weights/styles, so depending on the language you're writing in a single WOFF file might be missing a few letters.
Not as an application file format discussed in the link, though. Lots of software use it as a database (as intended) it's also a base for Apple's Core Data.
It does, here's a schema from an image I just saved with the latest version. Pretty simple.
CREATE TABLE image_attributes ( name text, value blob);
CREATE TABLE layers (id text, parent_id text, sequence integer, uti text, name text, data blob);
CREATE TABLE layer_attributes ( id text, name text, value blob);
Also, document-based apps that use Apple's Core Data framework (kinda ORM) usually use SQLite files for storage.
I sent a pull request to an open source project and GitHub added Copilot to review it, saying I invited it to review, embarrassing me. It then spit out some nonsense. Turns out this is controlled by a switch somewhere, which was enabled.
I remember seeing this last time the McMaster site went around and it's great. It's wild to me though that ignorant reflexive copy-paste lashes against React like this thread OP are so common that there was value to putting this together.
Ackchyually, TextEdit now has built-in AI as any other native macOS textview control if Apple Intelligence is turned on. It even autocompletes your sentences.
It also likes to save to iCloud by default if you're signed in.
While you can setup passkeys with YubiKey, the most common intended use case is key pairs that are synchable via your Apple/Google/password manager account. So, once you add a passkey, you'll be able to sign in on mobile with it automatically.
