Unfortunately they cannot yet be resized on the fly, as instead some vertical-tab extensions allow you to do. But it's a step in the right direction!

Cheers! ๐Ÿ™ Unfortunately it's the same as on Sci-Hub, the "accepted version". It'll have to do.

Restored! Maybe worth a post update?

It's just part of a player's roleplay.

"Ethical and legal objections". The point in this case is that what's legal is unethical, and what's ethical is illegal. Analogous to other situations through history and countries, for example in the USA when it was illegal for black people to sit in certain parts of a bus, or in Germany when marriage with Jewish people was illegal.

As human beings, it's always important to make the ethical choice.

I'm actually a physics teacher ๐Ÿ˜‚ In fact, as I write in the post, these questions are more about self-reflection. They bring to light some interesting points or issues about Newtonian mechanics and the way we teach it.

Please see my replies in the cross-post https://lemmy.ca/post/33867210

Completely agree, which I think is very interesting. In Newtonian mechanics, some scalar and vector quantities such as mass, internal energy, contact forces (stress), heat flux are frame-indifferent. Others, such as velocity and acceleration, are frame-dependent but we do have transformation rules for them. Some quantities โ€“ and quite important ones โ€“ such as momentum, are in a sort of limbo: they are frame-dependent, but there's no clear transformation rule for them.

From the point of view of relativity theory, it's interesting to note that for this particular case of coordinate transformation โ€“ note that it is not a Lorentz boost โ€“ we can actually calculate the spatial components of momentum in the new coordinate system, if the reported momentum is expressed as a covariant vector (p_ยต). This is because its unknown temporal component (energy) gets multiplied by zero in this transformation. But the text is ambiguous on whether the reported components are covariant or contravariant.

Regarding the third body, consider the case where its mass is, say, 2โ€ฏkg, and the case where it's 1โ€ฏkg instead (the momentum being the same).

[โ€“] pglpm@lemmy.ca 0 points 7 months ago

Yes we're considering Newtonian mechanics in any case. What I'm especially curious about is what physical principles people use to motivate their answers.

Edit: Deleting all cookies by hand seems to have solved the problem. Probably related to the bug pointed out by @trackd@lemm.ee in the comments. Cheers!

My browser has an extension 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 โ€“ or am I wrong?

So I don't understand with which URL these cookies are associated with โ€“ 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 โ€“ย 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, 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?

Remember this theme? By chance I stumbled on it yesterday. Had forgotten about it and hadn't listened to it in years.

 

I'd like to change the preferred-application order for some mimetypes/file extensions, and trying to do that through the "File associations" tab of the System Settings Module. But the changes don't stick.

A look at .xsession-errors shows that some files must be corrupted. For example I see (NB: this isn't the mimetype I'm trying to change):

Mimetype Comment Dirty: old= "application/vnd.amazon.mobi8-ebook" m_comment= "Amazon KF8 ebook format"
Entry  "application/x-mobi8-ebook"  is dirty. Saving.

and similarly for several other obscure mime-types (e.g. "x-x509-ca-cert").

I've tried a reset as described here, by renaming the ~/.local/share/mime directory, creating a new ~/.local/share/mime/packages/ one, and calling update-mime-database ~/.local/share/mime. But it doesn't help. I manage to do and save one change in the File Associations settings, but after that, other changes won't stick anymore.

Something seems corrupted upstream.

Any suggestions? Cheers!

 

This is completely random, but... has a Gaussian distribution ever been made? It'd be absolutely hilarious :D

Sorry for the spam โ€“ mods feel free to erase!

For years I've been using DejaVu fonts, but in the last years I had the feeling that this project had been abandoned. And indeed it has.

Does anyone know of good open-source alternatives?

I've heard of GNU Unifont, which seems still alive, but it isn't the kind of font one would use for, say, slides or websites.

Liberation and Kurinto were interesting (though not au par with DejaVu, in my opinion), but seem to have been abandoned as well.

I'm tired of Google and personally am not interested in fonts commissioned by them.

You can find it at /c/typography@lemmy.ca or !typography@lemmy.ca.

I was looking for such a kind of community to post a question, but a search in https://browse.feddit.de/ showed that no such community seems to exist as yet in the Fediverse. So why not creating one.

 

I'm often seeing links to posts on Mastodon and, when I click on them, they open in a Mastodon instance different from mine (I mean from the one where I have my account). This means that I cannot reply, boost, etc, that post.

The very roundaboundaboundabout way to solve this is to go to your instance and search/"explore" for that post.

Is there a smoother way to address this problem?

I found 1001 "beginner's guides for Mastodon" online and after reading 3 without finding any solution, I decided to ask here.

A similar problem existed with communities (and still exists with posts) in different Lemmy instances, but luckily tools like the Lemmy Instance Assistant solve this rather smoothly with a click.

PS: sorry if this sounds like a rant โ€“ it isn't. Just asking for info. I'm sure problems like this will eventually be solved in the Fediverse :)
