Oh. I’m sorry if this was discussed previously… I only returned to lemmy a few weeks ago and didn’t see the story covered yet.

Could be what communities you are subscribed to. I run a small instance with about 3ish users, and here are my stats after about 3 months as well:

9.5G ./pictrs
12G	 ./postgres
8.0K ./lemmy-ui

What version of lemmy are you using? A recent update also introduced some space savings in the database (I think).

It comes down to bridging. I use discord and slack via IRC bridges. I actually use slack a lot (for work), but primarily through irslackd. I do not use slack for anything outside of work and would prefer to keep it that way.

For discord, I primarily use it through bitlbee-discord. With this bridge/gateway, I can actually chat on different servers at the same time, so I wouldn’t mind this for different communities if I had to.

Matrix is last because I don’t really have a good briding solution for it and it just seems clunkier than the other two for me.

I would be less willing to contribute/participate in discussions if newer platforms such as discord, slack, or matrix are used. Of those three, I would prefer discord, then slack, then matrix.

As it is, I only use Slack for work, and mostly avoid discord and matrix except for a few mostly dead channels/servers.

I understand that this is not the mainstream view and that most people prefer the newer platforms, but personally, I am not a fan of them nor do I use them.

I’m fine with IRC (actually prefer it as I use it all the time).

I agree with others that a mailing list is more intimidating and more of a hassle, but if there is a web archive, I can live with that. It wouldn’t be my preference, but it wouldn’t be an insurmountable barrier (I have contributed to Alpine Linux in the past via their mailing list workflow).

I think this is the author being humble. jmmv is a long time NetBSD and FreeBSD contributor (tmpfs, ATF, pkg_comp), has worked as a SRE at Google, and has been a developer on projects such as Bazel (build infrastructure). They probably know a thing or two about performance.

Regarding the overall point of the blog, I agree with jmmv. Big O is a measure of efficiency at scale, not a measure of performance.

As someone who teaches Data Structures and Systems Programming courses, I demonstrate this to students early on by showing them multiple solutions to a problem such as how to detect duplicates in a stream of input. After analyzing the time and space complexities of the different solutions, we run it the programs and measure the time. It turns out that the O(nlogn) version using sorting can beat out the O(n) version due to cache locality and how memory actually works.

Big O is a useful tool, but it doesn’t directly translate to performance. Understanding how systems work is a lot more useful and important if you really care about optimization and performance.

Yeah, this is what I do… I host a couple of ergo IRC servers and an instance of thelounge for those that want that interface (also offer gamja). Personally, I use weechat to connect to the server.

I think this is part of the recommended (external) nginx configuration for lemmy:

limit_req_zone $binary_remote_addr zone={{domain}}_ratelimit:10m rate=1r/s;

Which can be found here

There is a matrix chat: https://matrix.to/#/#lemmy-admin-support-topics:discuss.online

For Lemmy, I primarily use Photon and have contributed a little bit to the project.

Familiarity (my client distro is Pop and is based on Ubuntu), and I like the LTS life cycle (predictable).

I do uninstall snaps, though, and mostly just use Docker for things. I could use Debian, but again, for me it was about familiarity and support (a lot more Ubuntu specific documentation).

Currently self-hosting my own mastodon server and honestly the setup wasn’t too bad (using docker)… much more straight-forward than I feared.

My main concerns, which Julia mentions, is that if you have a small instance, you are very much an island as the way federation work is not what you expect. For instance, as Julia notes, if you view a new person’s profile on your own instance, it will look empty (as if they haven’t posted anything). Lemmy also has this issue if you view a community you have not subscribed to yet for the first time.

Likewise, my “#explore” tab is basically always empty and discovering new tags or people is difficult if you are just looking on your own instance (I basically have to go to Fossotodon or another instance to find new things and then import them into my own instance). I’ve recently learned that you have to have a third party application basically seed your instance with posts… again, similar to the bot tricks use for seeding Lemmy with communities.

Overall, I think discovery is a big pain point for the fediverse and ActivityPub. It’s great that we can have our own instances and control our own small communities, but it seems that we are lacking the ability to really connect across instances and form experiences that really bridge across multiple communities.

You can escape the :

URLS  = https\://foo.example.com
URLS += https\://bar.example.com
URLS += https\://www.example.org

Twitter and Reddit may have only lost a few million users to Mastodon and Lemmy so far, but these are nation-sized numbers, comparable to what Scandinavia is to the United States of America. The incumbents have allowed the fediverse to reach critical mass. It’s only gonna get bigger, but it already works well enough that I’ve no need for any other social network. It’s nicer here.

This resonates with me. Although they are still lacking for the long tail of small niche communities, Lemmy and Mastodon now have enough people and content that I rarely find myself going to Reddit or Twitter. The fediverse is not perfect and there is a lot of room for growth, but it is now large enough to be viable and hopefully sustainable.

Do you have a searxng folder in the same folder as your docker-compose.yml? If so, perhaps it is not mounting inside the container properly.

No, but basically jmp.chat takes over your phone number… it acts as your carrier for voice and SMS (similar to Google Voice). Maybe not exactly what you want.

From the FAQ:

You can use JMP to communicate with your contacts without them changing anything on their end, just like with any other telephone provider. JMP works wherever you have an Internet connection. JMP can be used alongside, or instead of, a traditional wireless carrier subscription.

The benefit of this is that you can receive voice and text on anything that can serve as a XMPP client.

You could consider using something like jmp.chat. It delivers SMS via XMPP (aka jabber), so you could self-host a XMPP server and receive SMS that way. It also has some support for MMS (group chat, media), but my experience with it was mixed (I used it for about 3-4 years).

I wonder if it is because of the various outages on both instance and the new “dead instance” detection, lemmy.ml has temporarily stopped receiving updates?

The federation code now includes a check for dead instances which is used when sending activities. This helps to reduce the amount of outgoing POST requests, and also reduce server load.

Indeed… :|

This looks incredibly cool and fun. Would be interested trying to re-write some of the games myself when I have some free time.
