freamon

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"
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"

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!

Hi. Just looking at what lemmy.ca sends my server:

From nginx log:

your.ip.address - - [20/Feb/2024:03:48:47 +0000] "POST /inbox HTTP/1.1" 200 0 "-" "Lemmy/0.19.3; +https://lemmy.ca"               
your.ip.address - - [20/Feb/2024:03:48:49 +0000] "POST /inbox HTTP/1.1" 400 0 "-" "Lemmy/0.19.3; +https://lemmy.ca"         
your.ip.address - - [20/Feb/2024:03:48:57 +0000] "POST /inbox HTTP/1.1" 400 0 "-" "Lemmy/0.19.3; +https://lemmy.ca"              

Dumping the JSONs reveals 3 duplicate files, all containing:

"id": "https://lemmy.ca/activities/create/0968bf93-ac05-4178-bf3f-28cdc65fc338"
"actor": "https://lemmy.ca/u/HairyOldCoot"
"object": {
  "id": "https://lemmy.ca/comment/7454502"            
  "content": "That was an episode of Sliders."
  "published": "2024-02-20T03:48:45.810068Z"

These are 3 Creates, not 1 Create and 2 Updates or anything. I've chosen a comment 'cos that's public info, but it's the same for all other activity too (Votes, Deletes, etc).

lemmy.ca isn't alone in this. endlesstalk.org sends everything twice (info posted here), as does lemmy.sdf.org and mander.xyz, but lemmy.ca is the only one I've seen send stuff 3 times. Other instances (e.g. aussie.zone, feddit.nl, lemm.ee, lemmings.world, lemmy.world, programming.dev, reddthat.com, sh.itjust.works, slrpnk.net) don't, but there's nothing obvious like lemmy version numbers to indicate the difference.

Whilst I'd prefer you didn't send me stuff 3 times, I'm mostly mentioning it because I doubt it's good for your own resources to send every activity by every lemmy.ca user out multiple times. Also, the OPs of my community are from Mastodon, so I imagine you're sending them the same message 3 times too ...

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.
