Well done! 💪🚀
This reminds me: what kind of Youtube replacement or quasi-replacement in the Fediverse? I've heard that Peertube may be difficult to maintain long term, which makes sense...

This is a fascinating phenomenon – but fully within current theory. And there's no "inversion of the arrow of time", despite what the sensationalistic, misleading title seems to imply. From the recent paper (my emphasis):
Our results, over a range of pulse durations and optical depths, are consistent with the recent theoretical prediction that the mean atomic excitation time caused by a transmitted photon (as measured via the time integral of the observed phase shift) equals the group delay experienced by the light.
The theoretical explanation is given in this paper:
We examine this problem using the weak-value formalism and show that the time a transmitted photon spends as an atomic excitation is equal to the group delay, which can take on positive or negative values.
It is essentially related to the difference between phase and group velocity of waves.
One more example of how nature – as we currently understand it – offers amazing, fascinating, unexpected phenomena. It doesn't need misleading sensationalism.

Personally I disagree on value of sex/nude scenes – but it's a subjective matter of course. Your final argument is absolutely fair and logical, and very general too. Extremely well put – I subscribe 110% to it!

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.

It seems to me these scenes are introduced in films to sexualize them. Most often than not they don't add anything to the story. But blood & sex get more viewers. So I find the whole thing hypocritical.
Brings me to mind an episode of the hilarious series "Coupling", where Jeff says that the actress in the film "The Piano" (?) was naked in the whole film. His friends say she wasn't, it was only a scene in the film. And Jeff replies "it depends on how you watch it" 🤣

Agree 110%! It's sad because it pushes back those people who were curious about alternatives and were willing to try. Hopefully things will improve with time...

I've tried different clients: Element web, desktop, and android, and FluffyChat desktop and android. The problems seems to come, as other have written, when the matrix.org server is involved: it's people from their handle there which experience glitches joining rooms in other servers. It seems this "part" of the fediverse still needs a lot of development.

Looks very promising! thank you for sharing. Seems worth trying and supporting.

Which can be further summarized: academics (🙋🏻) are basically a bunch of idiotic sheep, despite being in academia.

Really embarrassing also for the journals that published the papers – and which are as guilty. They take ridiculously massive amounts of money to publish articles (publication cost for one article easily surpasses the cost of a high-end business laptop), and they don't even check them properly?

As most who have already commented here, I'm somewhat unimpressed (and would expect more analytical subtlety from a scientist). Wittgenstein already fully dissected the notion of "free will", showing its semantic variety of meanings and how at some depth it becomes vague and unclear. And Nietzsche discussed why "punishment" is necessary and makes sense even in a completely deterministic world... Sad that such insights are forgotten by many scientists. Often unclear if some scientists want to deepen our understanding of things, or just want sensationalism. Maybe a bit of both...

The summary I just read sounds great, thanks for the tip!
A little advertisement for a new free online course about the foundations of data science, machine learning, and – just a little – artificial intelligence. It's been designed for students in computer science and data science, who could be uncomfortable with a head-on probability-theory or statistics approach, and who might have a lighter background in maths. The main point of view of the course is how to build an artificial-intelligence agent who must draw inferences and make decisions. As a course, it's still a sort of experiment. https://pglpm.github.io/ADA511/ In more technical terms, the course is actually about so-called "Bayesian nonparametric density inference" and Bayesian decision theory.

Thank you for the explanation! – it puts that sentence into perspective. I think he put it in a somewhat unfortunate and easily misunderstood way.
Can't help imagining Saitama putting a definite end, without so much back-and-forth, to Mahito's hateful smirk. One punch is all that's needed.
What are the comparative and superlative of the adjective "fun"? I'd say "more fun" and "most fun"... But I'm somehow slightly tempted by "funnier" and "funniest", which should be for "funny" though, not "fun"... I didn't find anything about this in the main dictionaries.
I wanted to tag SDF today. A `#sdf` came up, but it seems to refer to something(s) different. I also saw a `#sdfdotorg`. Is there a tag that's sort of "standard" to refer to SDF? Standard in the sense that it's typically used by ~~SDF members~~ [Edit:] Mastodon users interested in SDF.
matrix.org
Personal websites often give an email address for contact, as a `mailto:blah@blah.blah` link. And the address is often obfuscated in a variety of ways to avoid its harvesting by spam bots. If one wants to give one's [Matrix](https://fedi-verse.info/matrix-synapse) address in a website, what's the correct way of writing it as link? is it recognized as any kind of MIME (like `mailto:`)? And is Matrix-address spamming something possible and common? In this case, how should one obfuscate a Matrix address given in a website? Lots of questions from a noob :) Thank you for your explanations! **Edit for others with the same question:** as per [@QuazarOmega@lemmy.world](/u/QuazarOmega@lemmy.world)'s explanation in the comments, the Matrix address can be given as the link ``` https://matrix.to/#/@[yourusername]:[your.server] ```

We identify "life" with the capability of self-replication plus some other features. In other conditions, for instance on other planets, it could be possible for self-replication to happen in a way different from the RNA/DNA-based one. I remember stumbling, years ago, on research and papers that studied this kind of possibility. But I'm having a hard time finding the old references or new ones. Do you have interesting papers and research material to share about this? Thank you!
*[If this is off-topic for this community, mods please let me know and I'll delete it.]* **Edit:** Deleting all cookies by hand seems to have solved the problem. Probably related to the bug pointed out by [@trackd@lemm.ee](/u/trackd@lemm.ee) in the comments. Cheers! My browser has an [extension](https://addons.mozilla.org/en-US/firefox/addon/cookie-autodelete/) that deletes cookies left by any website as soon as all tabs with that website's domain are closed. I can whitelist some of course, but Google's domains (`*.google.com`,`*.gmail.com`) are *not* whitelisted. What's strange is that if I sign into Gmail, then close the tab or even Firefox, when I go into Gmail again I'm signed in automatically. I have no automatic sign-in functionality in Firefox, so this must happen because Google is saving cookies somewhere – or am I wrong? So I don't understand with which URL these cookies are associated with – it can't be `*.google.com`, because otherwise they would have been deleted. Can anyone enlighten me about this? [Not sure I've been able to explain myself clearly; apologies and let me know in case.]
I have degoogled myself when it comes to email, running self-hosted email & calendar (not my own server). Did it two years ago, and up to now it has worked very well. I don't miss anything from Gmail and have all the features it offered, plus some extra ones (like deleting email attachments via an email client – Gmail never deleted them, just archived them). It's good, however, always to have a backup email address that's not connected with your hosting service. Up to now I've been using Gmail for that, but in view of [recent developments](https://stackdiary.com/web-environment-integrity), I just want to ditch the whole Google business. I've seen that many people use Protonmail for this, and that's what I'm considering. I'd like to hear about more possibilities and experiences though. Maybe there's another provider that's friendlier or more consumer/internet-freedom oriented?
