Safari on iOS saves tons of tab state going back months, but it's not using all your memory, etc. I have never really done iOS programming so I don't know the details.
- astrange 6y agoThat’s called restorable state and it’s better than assuming everything can be always persistent, like Lisp/Smalltalk images did. For one thing, restarting all the time makes it less fragile. You don’t have to untangle your state that’s been persistent for months if there’s a bug in it.
