They don't seem to do that, though. Note that they claim that it's a random key and that deduplication is "much more likely" to happen when files are copied. If they would derive the key from the data in a deterministic way, they could always dedup and the previous statement (deduplication of copied files is more likely) could not be true.
Yes, but the first part makes no sense. If the 128-bit key is indeed chosen at random for each file (as it should be), the probability that the same key will be chosen again for a second upload of the same file is effectively zero (1/2^128).
I used the following heuristics (some parts added afterwards):
1. Helvetica has level edges, Arial is angled (as ef4 said). Particularly important were "t", "e" and "a", "S", "G", C".
2a. For capital letters, if there is an "R", the Helvetica one is curved in the bottom right part while Arial uses a straight line.
2b. For a capital "Y", the Arial one has the same length in all directions while the Helvetica one is shorter at the bottom. (Alexx indicated a difference).
2c. The jags/gaps in the capital "M" extend further to the top for Arial. This can be used to figure out MATTEL.
3. Otherwise, the one that looks fatter is Helvetica.
The question is "Should whiskey be prohibited or not?" but he takes it to be "Is there anything good or bad about whiskey?" or "Do I think whiskey is good or bad?".
The comment you replied to was certainly not a reference to Nazi Germany at all. Germans understand that a privacy-related reference to german history is usually a reference to the former state of East Germany which was famous for massive surveillance.
Yes, but it takes more than removing most of the identifying information.
First, the precise browser version and OS can probably always be identified by checking for supported features, bugs etc. even if the extreme measure would be taken to remove the user agent string.
Add the screen resolution, IP, timing and request patterns (+) and we are all screwed.
(+) e.g. rule out users that are using other sites at the same time. Note that it would be possible to determine if a page is in the currently focused and visible browser tab and forward that information to the tracker.
The expectation that customers should act in a way to basically create the conditions for a perfectly free market is misguided. Not invoking legislation just makes things painful for everyone. Sure, I can switch to Android - but the cost of buying everything again is rather high. Tomorrow I might have to switch back for similar political reasons.
Sure, but this was the case before CDNs as well. Unless you are a Tier 1 network you usually pay a fee to your upstream carrier.
However, the ITU would like to charge across many networks and discriminate based on the type of service provided.
So if data from your network A reaches the customer through networks B, C and finally D, then D would like to charge you to deliver it and not slow down things artificially.
