The irony of history. Scientists escaped from Nazism and Fascism to the USA almost a century ago. Now the same is happening again, for similar reasons, in the reverse direction.

Appreciated if someone can explain what is the problem and its context in simple terms 🙏

I understand the GNU "framework" is built on free, open source software. So I don't understand how one can "discover" that there were pieces of non-free software there... They were put there by mistake?

The current security philosophy almost seems to be: "In order to make it secure, make it difficult to use". This is why I propose to go a step further: "In order to make it secure, just don't make it". The safest account is the one that doesn't exist or that can't be accessed by anyone, including its owner.

It's utter bullshit from the very start. First, it isn't true that the Ricci curvature can be written as they do in eqn (1). Second, in eqn (2) the Einstein tensor (middle term) cannot be replaced by the Ricci tensor (right-hand term), unless the Ricci scalar ("R") is zero, which only happens when there's no energy. They nonchalantly do that replacement without even a hint of explanation.

Elsevier and ScienceDirect should feel ashamed. They can go f**k themselves.

"Bayesian analysis"? What the heck has this got to do with Bayesian analysis? Does this guy have an intelligence, artificial or otherwise?

This is actually already implemented, see here.

Yeah that's bullsh*t by the author of the article.

One aspect that I've always been unsure about, with Stack Overflow, and even more with sibling sites like Physics Stack Exchange or Cross Validated (stats and probability), is the voting system. In the physics and stats sites, for example, not rarely I saw answers that were accepted and upvoted but actually wrong. The point is that users can end up voting for something that looks right or useful, even if it isn't (probably less the case when it comes to programming?).

Now an obvious reply to this comment is "And how do you know they were wrong, and non-accepted ones right?". That's an excellent question – and that's exactly the point.

In the end the judge about what's correct is only you and your own logical reasoning. In my opinion this kind of sites should get rid of the voting or acceptance system, and simply list the answers, with useful comments and counter-comments under each. When it comes to questions about science and maths, truth is not determined by majority votes or by authorities, but by sound logic and experiment. That's the very basis from which science started. As Galileo put it:

But in the natural sciences, whose conclusions are true and necessary and have nothing to do with human will, one must take care not to place oneself in the defense of error; for here a thousand Demostheneses and a thousand Aristotles would be left in the lurch by every mediocre wit who happened to hit upon the truth for himself.

For example, at some point in history there was probably only one human being on earth who thought "the notion of simultaneity is circular". And at that time point that human being was right, while the majority who thought otherwise were wrong. Our current education system and sites like those reinforce the anti-scientific view that students should study and memorize what "experts" says, and that majorities dictate what's logically correct or not. As Gibson said (1964): "Do we, in our schools and colleges, foster the spirit of inquiry, of skepticism, of adventurous thinking, of acquiring experience and reflecting on it? Or do we place a premium on docility, giving major recognition to the ability of the student to return verbatim in examinations that which he has been fed?"

Alright sorry for the rant and tangent! I feel strongly about this situation.

I'm not fully sure about the logic and hinted conclusions here. The internet itself is a network with major CSAM problems (so maybe we shouldn't use it?).

In my case this translates to "Twitter is now deleted".

For me it’s like using a coffee machine as a stopwatch, and then complaining that it doesn’t always give the exact time lapsed.

I agree that the wording is inaccurate, but some of the essence remains: the second "service" is forced on you. It's somewhat as if anyone with a Fakebook account also automatically had a Whatsapp or Instagram account, or some permutation of this.
