I love the top gear reference, but surely May would have been the obvious choice, Hammond is just asking for a crash!

This whole episode is giving me flashbacks to the ActiveX days.

The tyranny of the default.

"Here mum, I've installed Firefox for you, it's better than Chrome in every way!"
"My knitting circle website doesn't work, I can't download patterns, it says I need Chrome"

Internet Explorer was effectively abandon-ware for a decade after Microsoft used their OS pseudo-monopoly to crush Netscape.
It took another tech giant abusing THEIR monopoly to relegate IE to the trash heap it should have already been on.

Comforting and Terrifying.
Comferrifying?
Terriforting?

So you won't use your banks website?
Or your utilities (gas/water/electricity/internet)?
You won't let your kids use the portal at their school for submitting assignments?
Your government sites for renewing your drivers license or scheduling hard refuse pickup?

I can think of lots of reasons that will force me to have chrome installed if this goes ahead.

My understanding is that no one on that instance can see any of us on any instance.
So no, they couldn't post to lemmy.world.
They could post to somewhere we both federate too, such as lemmy.ml and we would be able to see that post, but if we respond to them, they wouldn't see our post.

If you look at the instances page at beehaw, lemmy.world is still listed as blocked:

https://beehaw.org/instances

I can't see that log, the url appears to be truncated.
This is a weird one.
I assume your movie library in Jellyfin is targetted at the root? /media/Filme ?
I also assume you have your localisation set to french, have you tried temporarily setting it to us english and restarting the docker instance?
I've seen weird things happen if the docker instance starts before the mount, so if /data/Filme is a mount, it's worth manually restarting your instance:
sudo docker restart jellyfin

Do you have nested libraries? Like a library pointed at /media and another one pointed at /media/Filme and maybe another at /media/Filme/Comedies ?

I'm pretty sure Firefox doesn't know how to cast, that's a chrome feature.
Secondly, a chromecast dongle can either be targetted locally by an app (such as chrome) or over the internet via https.
If you are just hosting on your windows laptop, you probably don't have a domain with TLS, yes?
From localhost (the laptop itself), if you run chrome, you can probably cast to your dongle whilst on the same LAN.

If you have one of the newer Chromecasts with the remote, you can simply install the Jellyfin app on it directly, and address your Jellyfin install by IP and port.

Plex uses some fancy redirection work around these limitations, but it relies on an external service that they provide.

When you set up your libraries, it's important that you point the path at the root folder, jellyfin expects a fairly specific naming convention.
Here's how it is suggested to setup your tv shows for instance: https://jellyfin.org/docs/general/server/media/shows

Simplistically, lets say you have 2 shows called "Friends" and "The Witcher", each with multiple seasons, and your NFS mount is /mnt/media.
You'd create something like: /mnt/media/tv
That's where you'd point your tv library, at that "tv" directory. It doesn't actually matter what the directory is called, but the library should be of type "shows".
Under that /mnt/media/tv directory, you would create a directory for each show, and it would be the name of that show, so you'd get: /mnt/media/tv/Friends/ and /mnt/media/tv/The Witcher/
Then under those directories you would create seasons, to put your episodes in, ie /mnt/media/tv/The Witcher/Season 01/The Witcher - 01x01 - The End's Beginning.avi
/mnt/media/tv/The Witcher/Season 01/The Witcher - 01x02 - Four Marks.avi

If you pointed the root of your library at /mnt/media/tv/The Witcher/Season 01/, it would probably fail to parse the episodes.
If you create your library as /mnt/media/allmystuff/ and just ram everything in there, it's unlikely to find anything.
This may all seem a bit complicated, but there's lots of tools that are useful to automate this process.
I personally recommend https://sonarr.tv/

If you are doing all of the above correctly, we'll have to dig a bit deeper for more details.

As for "unsupported formats", that most commonly happens when you have enabled hardware acceleration and it's not working properly.
Whilst there's several reasons why it may not be working, to rule it out, try temporarily disabling Hardware Acceleration under Dashboard -> Playback -> Transcoding.
The system should fall back to CPU transcoding which may be slow (hardware dependent), but at least it should function.

I don’t know if Leo cares about that anymore. He’s been saying he’s done with Twitter for a few weeks at least.

At least a year.

But in a recent TWIT (2 weeks ago maybe), all of the guest panelists admitted that they were all still maintaining their followings on Twitter and hopeful that they could move to Threads.

It's all just whores being whores, which is what Elon is relying on.

I'd sign up to Titter.

The US (which is where I assume you are), has the second largest one in the world in current operation:
https://en.wikipedia.org/wiki/Bath_County_Pumped_Storage_Station

Short answer, it scales fine.
Now you need to find someone to pay for it.

The Back to the Future trilogy is good for a re-view.

Yes, but you would be seeing ALL posts from everywhere your instance knows about.

I kind of like the idea of being on lemmy.world, filtering to say aussie.zone and getting it to show me local.
Or being able to simply get a list of every community on another instance.

These are cool ideas.

In progress as I cooked.
The post image is the final product

The annoying thing to me is that it's taken a further 13 years to reach a point where another social network is feasible.
I'm not saying there haven't been attempts like diaspora and the early mastadon etc, but now we're actually reaching a critical mass of participants where a move is worth it.

The same is true of Signal. I've been using it for nearly a decade, but it's only in the last 2 years that people haven't rolled their eyes when I mention it's my preferred comms app.

The first 90% of the task takes 90% of the time.
The last 10% of the task takes the other 90% of the time.

It'll be 0.18.1 with a specific patch applied to it to fix the security issue that got the site exploited.

It's hard to search for it on a phone, but something in here will match it: https://github.com/LemmyNet/lemmy/commits/main

I mean yes, but that's not a federation problem.

To completely strawman AND slippery slope what you're saying:

As a car safety pro, who primarily deals with car crashes:

STOP

TOWING

TRAILERS

Agreed, dangerous, I don't want numpties doing it.
But it's a large part of why I have a car.

I want to be clear, that I disagree with his "federation is stupid" point, but email has problems right now.

Theoretically it's federated, theoretically you can spin up your own mail server and self host.

But even if you do that absolutely perfectly (SPF, DKIM, DMARC etc), you can falsely end up on spam list, that effectively block delivery of your email to large segments of the network for days if not weeks.

Whilst theoretically federated, email falls under the broad dominion of google, microsoft and a couple of other large players.
