Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      Much more of the standard library could have been available for lower-level use. There could have been a collections and io library usable without those design decisions, etc. It was a very explicit design decision to have such lackluster low-level stdlib and ecosystem support.

      Rust gained support for fallible allocation recently.https://github.com/rust-lang/rfcs/pull/2116 …

      Not a fan of how any of this stuff ended up at all. :\ Seriously regret wasting so much time contributing to the Rust compiler / standard library now. It was so close to ending up as a great language for low-level use but the standard libraries missed the boat completely.

      Aborting on OOM makes complete sense at the application layer. For example, Android forces applications to do everything with transactions and to support being killed / respawned at any point without losing state. That's a good model and it fits perfectly into that.

      It absolutely does not. It means losing valuable work/data. Android apps do not honor the contract they're supposed to because it's hard to do.

      YouTube even loses your scroll position in a huge list if you switch apps, without any kill. Nothing reliably keeps data across getting killed.

      Activities are killed and spawned again simply by rotating your screen.

      You don't really know if an app is being killed when it's in the background. That's probably what's happening to YouTube for you. It still being in the least of recent apps doesn't mean it wasn't killed.

      So sure, some apps are buggy. If the YouTube app is wrapping web content, the reason would probably be that it's a lot harder to do this for content in a WebView vs. native content with proper support for it. Browsers make it hard to restore scroll position, etc.

      Using transactions for actual data is easy, as is saving content the user was working on. It's definitely harder to restore the *view* to exactly how it was after dealing with an activity respawn but that's not lost data, it's an inconvenience.

      Loss of view is loss of data. Consider a list of all strings length N where you're looking at the one you care about. MVC model is wrong; the view too needs a model behind it.

          Real-world case is of course the one search result you wanted among tens of thousands of junk results, or the one tweet you wanted to reply to in nondeterministic timeline.

          You're supposed to save / restore all of that, and good apps do, but some developers cut corners. WebView isn't really native content and the web isn't designed to save state so that's why web-based stuff doesn't do this as well.

          Some developers *disable* configuration changes like screen rotation, keyboard opening, etc. to mask that they didn't properly implement using transactions and also saving / restoring activity state as needed.
