The question isn't whether you can statistically measure an effect, it's whether the effect is large enough to justify the effort and expense. It would be interesting to see a real study that accounts for confounders like site imp

Both of those are comparing a 3-core iPad with a 2-core Intel CPU. And parity at the same TDP is unsurprising. The trouble is that the i5-7Y57 is quite slow by desktop standards and there is currently no ARM equivalent to 4+ core 45+ watt I

The main benefit of IPv6 is that it allows all endpoints to have a real IPv6 address, including the ones that don't have a real IPv4 address. It serves its purpose if it allows end user devices to directly communicate with each other e

It seems like the problem is that you need to verify that the file actually exists there with the specified hash, but that isn't the same as having to download it. Is there a way to ask the server for just the hash of a file? You would

Possible solution is to have a content hash proxy trusted by the user but shared between multiple users. Then the site can only get the data at the proxy-level rather than the user-level, and not even that if the proxy is large enough to ju
