On: JSMpeg – Decode It Like It's 1999

JS hack idea! Play a silent sound to force Chrome to not throttle your page when it's not primary.

[nix0n → koolba]

Please don't.

Also, Chrome puts a little speaker icon on the tab, so users might notice.

[recursive → nix0n]

In the long run, the probability of this being exploited is approximately 100%. I'm surprised they left in such an obvious loophole.

[daurnimator → recursive]

I'm not sure how usurping this is an 'exploit'. It's used as a heuristic to save battery life.

and if you're trying to run down a user's battery I can think of better ways.

[recursive → daurnimator]

The goal isn't to run down the users' battery. The goal is to do whatever timer callback processing a tab is doing that got throttled in the first place.

[dzhiurgis → daurnimator]

Well you can mine bitcoins or run some botnets on victims computer.

[Ezhik → koolba]

Need to do some more testing, but I have suspicions that Chrome actually doesn't put the sound icon on the tab if it's playing silent audio.

[koolba → Ezhik]

Throw in an inaudible frequency once per second at a low volume. I doubt they're doing signal processing to decide if a human can actually hear the output.
