Lemmy doesn't seem to get much recognition in the wider Fediverse - it tends to get bundled as part of 'other apps'. Mastodon is much bigger, so better integration with Lemmy probably gets deprioritised below their own issues and feature requests (e.g. I was reading today that Markdown support is often requested, but the base version still doesn't have it)

I don't think it's technically impossible - all the information that another site needs to properly interpret some activity is in the JSON that's sent. I get the sense that it might be unrealistic to expect Mastodon to make the necessary changes though. It seems more of a political issue than a technical one.

It's partly an issue of keys. Every fediverse actor has a private key and a public key. When my instance sends this to fediverse@lemmy.world, it's signed by my private key, and lemmy.world uses my public key to verify it. When fediverse@lemmy.world sends this comment out, it uses it's own private key to sign it. It can't just re-transmit my comment, because it doesn't have my private key. All it can do is Announce that I've made the comment (and sign the Announce).

Mastodon treats Announces as Boosts, so every post/comment is interpreted as a thing that fediverse@lemmy.world has boosted, so you get all these un-connected posts appearing. I think it's mostly up to Mastodon to remedy.

It works better if a Mastodon actor posts into a Lemmy community, then you get the mix like you imagine. e.g.: https://mastodon.world/@Flash/112095241193510662 (this particular post was crowbarred into Lemmy via !tails@lemmon.website, but it would be the same if the author had done it.)

Edited to account for blahaj updating to 0.19.3 ... hopefully that's the last big instance to change.

It's been about a week since sh.itjust.works and lemmy.world updated, so results from those instances will start appearing again soon.

Bit mad, as in a bit strange - e.g. "it's a bit mad to take a single word out of its obvious context for such a desperately cheap shot".

[–] freamon@endlesstalk.org 7 points 1 year ago (6 children)

Wait, what? A user posts a thing to a server, and that thing isn't then duplicated to 50 other servers ... yeah, I don't see how that can work.

(I'm just kidding - your site looks neat.)

[–] freamon@endlesstalk.org 5 points 1 year ago

!quickanimalfacts@lemm.ee - yeah, go on then. subbed.

[–] freamon@endlesstalk.org 1 points 1 year ago

Oh, yeah, cross-posts are great - I think it's something we're all supposed to be doing. I wouldn't say anything usually - just thought this image might raise questions that the creator could perhaps answer.

[–] freamon@endlesstalk.org 2 points 1 year ago (2 children)

(sorry to intrude). This has had a few cross-posts on Lemmy. The link that goes to !tails@lemmon.website is attributed to the author of the image, so you can reply to them via that community if you wish.

(sorry to intrude). This has had a few cross-posts on Lemmy - this one technically wasn't, but it seems Lemmy has picked up on it. If you want some ALT text, and to reply to author of this image, the link that goes to !tails@lemmon.website provides that.

[–] freamon@endlesstalk.org 1 points 1 year ago (1 children)

Errr ... I want to say it was in Captain America, but I was being vague 'cos I can't really remember. I wasn't expecting to be quizzed on it tbh.

The crawler at lemmyverse.net has picked up on an ngrok URL I've used for messing around with Lemmy. I was using it last night to play with PieFed, and saw it make about 20 attempts to read an API that isn't there. I thought - oh, I wonder if that will break it - and sure, enough, there wasn't a 6:00 update from it this morning. Ho hum.

 

This is probably just me, but I found INSTALL.md to be a bit confusing.

So, for a fresh install of Ubuntu in a Windows Hyper-V VM, this is the list of steps I took to get something that at least looks like it might be the right thing:

remove unattended-upgrades, and clean up after OS install

sudo systemctl stop unattended-upgrades
sudo apt-get purge unattended-upgrades
sudo apt autoremove

install postgresql 16

sudo apt install ca-certificates pkg-config
wget --quiet -O - [https://www.postgresql.org/media/keys/ACCC4CF8.asc](https://www.postgresql.org/media/keys/ACCC4CF8.asc) | sudo apt-key add -
sudo sh -c 'echo "deb [http://apt.postgresql.org/pub/repos/apt/](http://apt.postgresql.org/pub/repos/apt/) $(lsb_release -cs)-pgdg main" >> /etc/apt/sources.list.d/pgdg.list'
sudo apt update
sudo apt install libpq-dev postgresql

install python libs

sudo apt install python3-pip python3-venv python3-dev python3-psycopg2

install redis server

sudo apt install redis-server

install git

sudo apt install git

set up database

sudo -iu postgres psql -c "CREATE USER pyfedi WITH PASSWORD 'pyfedi';"
sudo -iu postgres psql -c "CREATE DATABASE pyfedi WITH OWNER pyfedi;"

clone PieFed

git clone [https://codeberg.org/rimu/pyfedi.git](https://codeberg.org/rimu/pyfedi.git)

cd into pyfedi, set up and enter virtual environment

cd pyfedi
python3 -m venv ./venv
source venv/bin/activate

use pip to install requirements

pip install wheel
pip install -r requirements.txt

edit .env file

cp env.sample .env
nano .env
(change SECRET_KEY to some random sequence of numbers and letters)

initialise database, and set up admin account

flask init-db

run the app

flask run
(open web browser at http://127.0.0.1:5000))
(log in with username and password from admin account)

Maybe this will help someone else (or maybe someone has spotted something that I missed - like I say: it looks right when loaded in a browser, but I'm not 100% sure)

 
 

From my nginx access log:

your.ip.address - - [21/Feb/2024:06:50:09 +0000] "POST /inbox HTTP/1.1" 200 0 "-" "Lemmy/0.19.3; +https://lemmy.sdf.org"
your.ip.address - - [21/Feb/2024:06:50:09 +0000] "POST /inbox HTTP/1.1" 400 0 "-" "Lemmy/0.19.3; +https://lemmy.sdf.org"

2 of the entries are "https://lemmy.sdf.org/activities/like/88bc5b6d-f11f-4245-90aa-908e43befe97" being sent twice,
the other two are "https://lemmy.sdf.org/activities/like/437327e5-a262-46bc-8ce7-1c2c5bd440b3" being sent twice

I've reported this problem to other affected servers that I've seen:
the lemmy.ca post suggests the problem was something to do with running multiple containers with the same index number;
the endlesstalk.org post suggests that re-starting the backend containers is a fix
(their answers will likely more sense to you than to me, as I don't run lemmy).

Thanks!

 
 
 

After 6 years, project 4K80 (the 4K fan-edit of Empire Strikes Back) finally has some release candidates.

The linked post details why it took so long (compared to 4K77 and 4K83), and the plans for the future.

It's something I'll download when they've worked on it a little more. For now though, Adywan's 'The Empire Strikes Back Revisited' remains my favourite version.

 

Given the shared underlying protocol, I didn't like that if I saw something interesting on Mastodon, and wanted to post it on Lemmy, I'd have to screenshot it and/or re-attribute it to me rather than the original author.

Tails is an experimental community. Instead of announcing just what a Lemmy user has posted, it announces what a Fediverse actor has posted. This means that, so far, it's featured posts from Mastodon accounts like Mr Lovenstein, warsandpeas, George Takei, Low Quality Facts, and other interesting people. Lemmy users have been able to reply to the author, and have also replied to those other Mastodon accounts that responded.

You can see for yourself at !tails@lemmon.website

(the usual rules apply: if you're the first person on your instance to do this, you'll likely get a blank screen or an error. Wait 10 secs or so, press refresh, and you should have it).

I'll reply in the comments with a example of what lemmy sends for each thing you can do (I think I've thought of everything, but you can probably guess the format if not, or I can always add it).

So, the setup for these is:
Our instance is called 'local.com'
Our user is called 'freamon'
The other instance is called 'remote.com'
The community on that instance is called 'interesting'

For many of these, remote.com will receive them, and rewraps them in an Announce to send out to all the other instances with a copy of the community, so everyone stays in sync.

Sort by 'Old' for the best hope of these making sense.
I'll follow this post up with a script, that can be used to send these activities from the command-line, as I think it can help to understand Lemmy if you're using something much simpler than Lemmy to do some of things Lemmy does.

EDIT: As nutomic as mentioned, a better list is in the docs. It's the kind of thing I should read first, I guess.
