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

(nothing to do with PieFed, just some necessary Ubuntu weirdness)

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 | sudo apt-key add -
sudo sh -c 'echo "deb 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

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!

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 ...

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.

The original Dislike activity (https://endlesstalk.org/activities/dislike/e1f82f6a-d49b-4dab-b444-36c382f13c5a) has a record at endlesstalk.org, but the Like object's activity that's been undone doesn't (https://endlesstalk.org/activities/like/1f0b6132-547e-4fb5-8313-6f7b7f31be6b just returns 'No record found')

I got the same results when I tried this from lemmy.world (but I thought I'd try again from a 0.19 instance)

I found some references to this at the GitHub, but they were issues that were closed off as being fixed, so I don't know what the situation is with this now.

From Deadline

The Idol is one and done at HBO.

The controversial series from Euphoria creator Sam Levinson and Abel Tesfaye, better known as The Weeknd, will not be returning for a second season.

It’s not a huge surprise given the critical and commercial reception of the show, which starred Tesfaye and Lily-Rose Depp. It also came after extensive reshoots following the departure of director Amy Seimetz, as revealed by Deadline in April 2022, and a reduced order taking its total number of episodes to five.

Some of the cast did mention the possibility of a second season during interviews, though show insiders said that creators did not come into the production process with a plan for a multi-season arc.

Da’Vine Joy Randolph, who played one of the managers of Depp’s pop star Jocelyn, previously said that the first season was left intentionally open-ended for the possibility of a second.

“The Idol was one of HBO’s most provocative original programs, and we’re pleased by the strong audience response,” said an HBO spokeswoman. “After much thought and consideration, HBO, as well as the creators and producers, have decided not to move forward with a second season. We’re grateful to the creators, cast, and crew for their incredible work.”

My opinion on this show is entirely out-sourced (I never watched it), so my snarky title might not be warrented
