Find a USB stick in the parking lot? Don't plug it into your PC and probably destroy it with fire.

Find a USB stick while digging in the park? Plug that baby in, jam to some Back to Black, and watch some vintage porn.

Basically the only thing you want to present with a challenge is the paths/virtual hosts for the web frontends.

Anything /api/v3/ is client-to-server API (i.e. how your client talk to your instance) and needs to be obstruction-free. Otherwise, clients/apps won't be able to use the API. Same for /pictrs since that proxies through Lemmy and is a de-facto API endpoint (even though it's a separate component).

Federation traffic also needs to be exempt, but it's not based on routes but by the HTTP Accept request header and request method.

Looking at the Nginx proxy config, there's this mapping which tells Nginx how to route inbound requests:

nginx_internal.conf: https://raw.githubusercontent.com/LemmyNet/lemmy-ansible/main/templates/nginx_internal.conf

 nginx

    
    map "$request_method:$http_accept" $proxpass {
        # If no explicit matches exists below, send traffic to lemmy-ui
        default "http://lemmy-ui:1234/";

        # GET/HEAD requests that accepts ActivityPub or Linked Data JSON should go to lemmy.
        #
        # These requests are used by Mastodon and other fediverse instances to look up profile information,
        # discover site information and so on.
        "~^(?:GET|HEAD):.*?application\/(?:activity|ld)\+json" "http://lemmy:8536/";

        # All non-GET/HEAD requests should go to lemmy
        #
        # Rather than calling out POST, PUT, DELETE, PATCH, CONNECT and all the verbs manually
        # we simply negate the GET|HEAD pattern from above and accept all possibly $http_accept values
        "~^(?!(GET|HEAD)).*:" "http://lemmy:8536/";

It kinda can but not as easily.

Back when I just downloaded everything under the sun on Napster/Limewire, I'd make highly curated CDs of known-hits as well as ones where I sprinkle in some random songs that were in my downloads that I'd never heard before. Not exactly the same, but I've definitely listened to a CD I made and been like "what's that song?! I love it!".

Plus, for road trips, everyone would usually burn a CD or two of their own to swap in (a precursor to "pass the aux cord") so there was some novelty/variety.

Nothing hits better on a drive than a good mixed CD. Even making a playlist on your phone, which is basically the same thing, is totally not the same.

Ran into a hiccup while trying to reproduce (there seems to be considerable lag between adding a domain to the filter list and the federation processes handling it), but now that I was able to reproduce it successfully, I made a bug report: https://github.com/LemmyNet/lemmy/issues/6320

Admiral Patrick @dubvee.org 7mo ago

Yeah, I think it was changed in Win 10 (or maybe 8/8.1?)

Finally, I'm not the only one noticing this.

I've long said that the moment "My Computer" changed to "This PC", it showed how MS really thought of your computer as theirs that they so graciously allow you to use once in a while.

Granted, I don't think the instance level URL filters were meant to be used for the domains of other instances like I was doing here. They're more for blocking spam domains, etc.

e.g. I also have those spam sites you see in c/News every so often in that block list (e.g. dvdfab [dot] cn, digital-escape-tools [dot] phi [dot] vercel [dot] app, etc) , so I never see/report them because they're rejected immediately.

During one of the many, many spam storms here, it was desired by admins for those filters to stop anything that matched them from federating-in instead of just changing the text to removed on the frontend. So it is a good feature to have. Just maybe applied too widely.

Though I think if a user edited their own description to include a widely-blocked URL (no URLs are blocked by default), they'd just be soft-banning themselves from everywhere that has that domain blocked.

If a malicious community mod edited their communities' descriptions to a include a widely-blocked URL, then yeah, that could cut off new posts coming in to any instance that has that domain blocked (old posts and the community itself would still be available).

All of those would require instances to have certain URLs blocked. The list of blocked URLs for an instance is publicly available from the info in getSite API call, so it wouldn't be hard to game if someone really wanted to. Fortunately, most people are too busy gaming the "delete account" feature right now 🙄.

The person who cross-posted it was ~~probably~~ definitely from your local instance.

You only ever interact with your local instance's copy of any community, even remote ones. If the community is to a remote instance that is either offline or since de-federated, there's nothing that prohibits you from interacting with it*. Because lemm.ee is no longer there to federate out the post/comments to any of the community's subscribers, only people local to your instance will see it.

*Admins can remove the community and, prior to it going offline, mods can lock it. But if an instance just disappears, you can still locally interact with any of its communities on your instance; the content just won't federate outside your instance.

Admiral Patrick @dubvee.org 7mo ago

I haven't looked. Just noticed it earlier today and haven't had time.

Admiral Patrick @dubvee.org 7mo ago

Lol. I guess now I gotta decide which is more annoying: Not having content from c/Books or having to deal with unwanted spillover from .ml. I don't have the chutzpah to ask the mods to change the community description lol

Just figured this might catch other people off guard like it did me. I never would have expected the community description to be evaluated for the URL filter (only posts/comments).

I wouldn't recommend it to anyone in real life. There are parts that are just way too jarring.

Ugh, this. And I hate that it's like that.

Like, I used to have my instance open to whoever to sign up. My guiding principle was to have a place that wasn't overrun with [parts that are just way too jarring]. Holy shit was that an impossible goal to do alone so I shuttered it up and now it's just a private instance / testbed for Tesseract.

My friends knew I was active on Reddit, and that was fine. But I wouldn't tell them I spend any amount of time here because what they would see going to almost any random instance will ~~probably~~ definitely not look good on me by association despite that I'm nowhere near that.

So if anyone shares this desire, I am open to un-mothballing my instance, rebranding, and taking on new admins and re-opening to users who also want a place like that.

I haven't been to Odysee for a good while, but is it still Rumble-lite?

I only learned of Odysee because I saw a video linked to it here and went directly to the video. When I saw it had embed code, I added support in Tesseract UI so the videos would play from the post. Then I went to the main site and saw the front page full of rightwing nutjob rants and vaccine skepticism and was like "nope". Had I saw that beforehand, I wouldn't have added embed support, but the work was already done so I left it in. That's basically why I refuse to add embed support for Rumble.

Wondering if ownership/leadership/policies have changed since about 2 years ago when I wrote the embed components for it and last interacted with it.

Admiral Patrick @dubvee.org 7mo ago

I totally get that.

The closest active alternative I can find is !screengrabs@piefed.social but it's for still images. Maybe if the clip fits the theme there, they'll allow it?

Admiral Patrick @dubvee.org 7mo ago

Only one I can find is !movieclips@lemmy.world but it's 3 years old and has 0 submissions. Maybe you can revive it? Surprisingly, the mod for it is still active on the platform.

Otherwise, "if you build it, they will come".

Lol. I would need several extra hands to count the number of times I've had people email me documents with filenames like Copy of new york (2) REVISED-final(1).docx
