On the other hand, social media platforms inject content that is popular, according to the number of "likes" and "reposts" into your newsfeed. It means the content has gone viral and it has already spread to several clusters around you, most of them centered around some other topic and, therefore, unable to properly evaluate it.

To answer your question, I don't think it will completely filter misinformation, but I think this strategy is better than anything Facebook and Twitter can come up with.

The problem is automated newsfeed, which makes users read "recommended" content and ads instead of allowing them to choose which sources they trust.

The real solution is to switch to Mastodon and similar federated networks, where everyone can select who to follow and receive nothing else. It is easy to subscribe to actual people with similar interests who "boost" (repost) the kind of content you like. They filter out misinformation way better than any of those Facebooks and Twitters can ever do.

You only need to measure three angular momentums, all other can be calculated. See https://en.wikipedia.org/wiki/Moment_of_inertia#Motion_in_sp...

"This shows that the inertia matrix can be used to calculate the moment of inertia of a body around any specified rotation axis in the body."

On the attacker side, they only need to make sure three angular momentums match.

The real solution to censorship is federation. We are bad at making decentralized search engines, and projects like YaCy [1] have never been successful, partly because it is hard to make ranking algorithms decentralized. But projects like Mastodon [2], Pleroma [3] and PeerTube [4] already have made federated social networks where you can decide what you subscribe to and receive it regardless of someone else decisions. The technical part is simple and transparent and if your provider tries to censor the sources you like, you can always switch to another one or host it yourself.

Surely you have to backup your data, but this case has nothing to do with information access.

Vote is simply an excuse used by the government to silence protest.

It is an obvious backdoor.

They justified XORing in arbitrarily string into the key you have established with DH with the fact that your phone may have bad random number generator. But it obviously gains you nothing. If the server is honest, then it does not read your secret chat anyway. And if the server is malicious or compromised, it knows the string.

So even if it is possible to overlook the possibility of XORing in the difference of keys and evading MITM detection, it is very unlikely that no developer (for example, someone who coded it into the server or one of the clients) have seen that it gains you nothing in any scenario you can think about.

When users started to asking developers for the explanation in the comments, W_K (main developer of the protocol, brother of Pavel Durov) stated that they "don't know" who added this feature in its current form. Shortly after, he stopped using his account or answering any questions at all: https://habr.com/users/W_K/

Upd: regarding the remark in the end of the https://habr.com/post/206900/ that "the story ended well", Telegram team is responsive etc.

Keep in mind that they paid this guy. Adding such updates to articles and publicly confirming that the bug was fixed is almost surely a part of the bug bounty agreement.

I am still sure there are enough industrial, medical and civil applications for Google to work on, no need to resort to "photo albums" immediately.
