They are launched with identity-keys which are, under proper processes, unique & secret. These are potentially rotated to new keys created off-world, early, so that even if unauthorized on-world keys remain, the window that those could

The private key could be generated after the probe leaves Earth, via a process where many competing parties contribute seeding information. Hence, barring deep compromises of the hardware, it will have never existed on Earth - only in the d

If you strip the envelope of crypto-hate, this is a really interesting idea to put transaction-validators on space-probes that are rapidly moving away from Earth. There, they can't be coerced by terrestrial bullies - be they 'au

Thanks! So, this process sends the user's photo to Apple without the user's knowledge or approval. If it is determined to be a false-positive, is the user informed that their data was exfiltrated?

Your interpretation might be right, but Apple's vagueness might be strategically hiding things they know would be even more unpopular, if revealed. Still, there's the question of what additional assurance this "manual review&

Perceptual image hashes are a hard problem. Searching for subversive text strings is easy . And, a bunch of the obscuring-of-surveillance-intent achieved here is oblivious as to the types of detection-events - not at all image-specific.

Many of these steps are spun as being for the users' privacy. But they also prevent the operators of the system – Apple Inc, quasi-governmental non-profits (like NCMEC), & government law-enforcement agencies – from facing accountab

Indeed, this is a 2013 article, largely based on a favorable/credulous reading of some 2012 & 2013 analyses from the EPI, a left/organized-labor/economic-protectionist/anti-immigration think tank. Those analyses were

Maybe given the length & complexity of a full human life, a bunch of brain factors actually work to slow specialization down to prevent early overfitting.

Something about this reminds me of the 'Winning Ticket Hypothesis' in artifical neural networks: that some 'random' initializations prime a network far better for later faster learning. From https://arxiv.org&

I believe iOS handles this by ensuring all flash-written data is encrypted with an on-device key. A 'wipe' then definitively erases that key - making further overwrites of the freed data unnecessary. If the crypto is strong, and t

It is interesting that none of the infection-recovered were infected - though with only 6 individuals, that could be luck. There have been other hints natural immunity is stronger versus later variants. But your other point doesn't f

The shifting of population regionally, and the aging of the population, are both good points to consider for proper controls. (In Australia, a fair-skinned population in high-UV latitudes suffers melanoma rates 50% or higher than the US. Ac

This sort of confounder is common, but we have in the US a population that, over the decades, is (pre-exposure) no more pale/susceptible-to-burns. The public has been bombarded for decades with the health message to avoid the sun, and

But, after 50+ years of rising sunscreen use, there's essentially no data showing more sunscreen use reduces skin cancer. Sunscreen definitely prevents sunburns, and almost certainly delays visible skin aging/weathering. Those may
