[1/4] If you've ever tried finding timing side channels by actually measuring, you probably know that this can be incredibly frustrating. But it does not have to! While major side-channels are easy to detect, more subtle ones, especially when the measurements are noisy, are not!

So, Google Chrome gives all *.google.com sites full access to system / tab CPU usage, GPU usage, and memory usage. It also gives access to detailed processor information, and provides a logging backchannel. This API is not exposed to other sites - only to *.google.com.
