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

      Halting problem is irrelevant. A pure functional language is Turing-equivalent but harmless because it has no side effects.

      I suppose it depends on what exactly you want to protect against. On one hand you can have "may only have an animated image with no JS" and on the other hand you have RowhammerJS/SpectreJS which would be difficult to defend against

      Um, blocking rowhammer is trivial. If you implement the vm you can limit store rate however you like.

      And if you detected anything nasty, you just abort loading the ad and switch to trying load from a different ad network.

      Force the networks to compete on not getting aborted for bad js behavior.

      Are you proposing always running the ad JS through the interpreter (as opposed to trying to check for bad behavior ahead of time)? I think this is possible in theory, but there's no real incentive for a site to do this.

      Sure, that's terrible. But are you _sure_ it ends up affecting the media outlet's bottom line? If the cost of lost subscriptions combined with the number that some fancy MBAs assigned to "loss of trust" ends up less than the cost of fixing their ads, then it won't happen.

      It's not easily measurable, and presently has no competitive disadvantage because they all do it. But it would if some made a point not to.

      But "having less shitty ads" might not drive "growth" as much as "print more clickbait" so this would need to be justified. Welcome to capitalism I guess?

      The way this would happen is a FOSS or reasonably priced commercial ad-sandboxer product appearing that's easy for publishers to install & use. They won't develop it themselves.

      Loading seems to be taking a while.
