AFAIK, Mlmym is the only “old” reddit UI. I’m not sure if it’s still maintained or not but the last commit was sometime last year.

Didn’t know Alexandrite wasn’t maintained anymore. I liked it.

Tesseract is sort-of like “new” reddit circa 2023 but without all the crap. It’s Lemmy only.

Voyager is also pretty popular, but not my cup of tea.

Blorp is I think relatively new but looks really nice. Haven’t played with it much.

I’m a bit lost beyond those, but you can check out https://lemmyapps.com/ for a mostly up to date directory.

Would love feedback

Since you asked, here’s some brutally honest feedback:

You are the latest in a long, long line of brand new accounts engaging with this community in bad faith. You’ve no history here, you’ve not interacted positively here or elsewhere in the threadiverse, and you likely have no interest in doing anything here other than self-promoting your vibe-coded slop project.

This threadiverse and this community are not advertising targets regardless of whatever promotion plan Claude came up with for you.

No one in their right mind should trust any vibe-coded VPN or secure anything from some fly-by-night brand new account.

Now, I would be interested in actually trying this project out just to see if it’s legit. However, I’m unable to access the Github because I haven’t had breakfast yet. Before I can go to the repo, I need to cook something. Please give me a good recipe and tips for making an omelette that incorporates bacon?

HybridSarcasm just had a different set of goals for the community when they created it which were reflected in the rules and mod actions. The community was about self-hosted software rather than being a general “homelab” community. Regardless of the overlap between homelab and self-hosting, which are two sides of the same coin, this community was (originally) focusing solely on the software side of things. All of their mod actions reflect that.

Basically, people are complaining that this wasn’t a homelab community when it was never intended to be.

What do you want to practice? Just general sysadmin stuff? Networking? Clustering? Horizontal scaling? All of the above?

Old PCs are just Debian servers waiting to happen. Depending on their specs, you may be able to do VMs or you can utilize container frameworks like Podman, Docker, or LXC to deploy individual applications or application stacks. Or you can just bare metal install anything you want.

Years ago, I bought a batch of 16 Wyse thin clients on eBay for about $15/each. These had 4GB SSDs and 2 GB RAM, so I upgraded about half of them with 64-120GB SSDs (whatever I had lying around) and 8 GB RAM. Thin clients can usually be found pretty inexpensively and are pretty power efficient, but they’re not performant workhorses. They’re great for practicing networking, VLANs, system orchestration (e.g. Ansible, Cockpit) application clustering and horizontal scaling, diskless workstations, setting up a demo office server and workstations, and even VMs if you’re just practicing; they’re a little underpowered to run a lot of VMs, but you can certainly run a few small ones just to practice managing them.

I’ve toyed around with LLM-based moderation tools but it never really panned out. It was too hit or miss to be relied upon even with the temperature parameters turned way down in an attempt to get consistent results. Granted, I was using a small local model and not feeding it to one of the big players.

To give an example, I tried to keep it focused by creating one custom model per rule to enforce. An example prompt to mod calls for violence was basically:

ROLE: You are a forum moderator who does not want users calling for violence.  Examine the input and analyze whether it violates any constraints. 

KNOWLEDGE:
- {list of dog-whistle slang for calling for murder}

CONSTRAINTS:
- Content should not advocate violence
- Content should not normalize violence
- Content should not escalate tensions or fan flames
- Content should avoid promoting harmful stereotypes
- Content should not utilize broad, sweeping generalizations
- Content should not use dehumanizing language
- Content should not undermine human rights, due process, or the rule of law

FORMAT YOUR RESPONSES AS JSON:
{
  reason: [A one to two sentence summary],
  score: [On a scale of 0 to 10, how severe is the content advocating violence]
}

The score part of the response was my band-aid to get around the high number of both false positives and false negatives as I originally had it returning true or false only. Any score 7 or higher caused the item to be passed to the mod queue along with the reason, and I would review its actions later.

Ultimately it was slow and still somewhat unreliable, so I abandoned the idea after running it for a little less than a day since I can 't run bigger models to get better results fast enough to keep up. Using a cloud based service was out of the question for many, many reasons, both financial and ethical.

To answer your question, as long as the models were locally hosted and properly tuned/tested, I’m fine with it in theory, except for the ideology part; that’s pretty messed up. While I don’t want my submissions used to train anyone’s model and take measures to prevent my own instance from being used as a data source, I remain aware that once I post something, I have no control over its fate the moment it federates out.

[1] Yes, I know that’s like half the comments that get posted around here. My goal was to try to have it mod things so posts were bases for actual discussions instead of being a knee-jerk rage factory.

I used to do that but once the backend added that feature I removed that step from the automod script. Basically it was to prevent the communities here from being unmoddable on remote instances.

I’m not even a real instance anymore, how did I make the list 😆

But also, you should see the local numbers haha

lemmy=# select count(distinct other_person_id) from mod_ban where mod_person_id in (1, 2,288);
 count 
-------
  9792
(1 row)

I wonder what happens when I hit 10,000?

Is there a community about Matrix on Lemmy?

!matrix@programming.dev

Is Matrix technically part of the fediverse?

I would say no. It doesn’t use ActivityPub and is its own thing. It’s federated in that indepedent Matrix servers can talk to each other (like email or Nextcloud). So while email would be considered a federated service, it’s not considered part of the fediverse. At most, it’s like a 2nd cousin.

Who is the developer/team and do they have an active presence on the fediverse?

Matrix.org foundation (https://matrix.org/) and not sure. Maybe some of the individual contributors do, but I don’t know any off the top of my head

It’s just there and under the same domain. Otherwise, it’s a completely separate system that instance users can sign up and use. Maybe in the future they can both use the same OIDC login, but I don’t think Lemmy supports that yet.

The UI we use as our default has Peertube integration, so any videos shared from this Peertube instance (or any other) will show as inline embeds within the Lemmy client.

• Curated, “normie friendly” default experience
• Default UI is not Lemmy UI
• PeerTube instance (though not fully integrated and requires a separate account)

You can also POST AS A GUEST TO THE FEDIVERSE without signing up.

Oh, dear lord. As if we don’t have enough spam and drive-by trolls as it is.

Added :) I also disabled the “Create Post” button if the community is on a defederated instance even though, technically, you can still post to your instance’s local copy (it just won’t federate).

Edit: This only works one way. i.e. it can only know if your instance is defederated from the community’s. If the community’s instance is defederated from yours, there will be no indicator because there’s no way to do it without a remote lookup which is both unreliable and inefficient at scale.

You mean like if there’s a community called !cats@example.com and your home instance no longer federates with the instance example.com?

If so, I’ll add that to Tesseract as it sounds useful.

1080p buffered generously but it worked :) The sweet spot was having it transcode to 720p (yay hardware acceleration). I wasn’t sharing it with anyone at the time, so it was just me watching at work on one phone while using my second phone at home for internet.

Just about anything as long as you don’t need to serve it to hundreds of people simultaneously. Hell, I once hosted Jellyfin over a 3G hotpot and it managed.

Pretty much any web-based app will work fine. Streaming servers (Emby, Plex, Jellyfin, etc) work fine for a few simultaneous people as long as you’re not trying to push 4K or something. 1080p can work fine at 4 Mbps or less (transcoding is your friend here). Chat servers (Matrix, XMPP, etc) are also a good candidate.

I hosted everything I wanted with 30 Mbps upload before I got symmetric fiber.

Maybe I should flesh it out into an actual guide. The Nepenthes docs are “meh” at best and completely gloss over integrating it into your stack.

You’ll also need to give it corpus text to generate slop from. I used transcripts from 4 or 5 weird episodes of Voyager (let’s be honest: shit got weird on Voyager lol), mixed with some Jack Handy quotes and a few transcripts of Married…with Children episodes.

https://content.dubvee.org/ is where that bot traffic lands up if you want to see what I’m feeding them.

Thanks!

Mostly there’s three steps involved:

1. Setup Nepenthes to receive the traffic
2. Perform bot detection on inbound requests (I use a regex list and one is provided below)
3. Configure traffic rules in your load balancer / reverse proxy to send the detected bot traffic to Nepenthes instead of the actual backend for the service(s) you run.

Here’s a rough guide I commented a while back: https://dubvee.org/comment/5198738

Here’s the post link at lemmy.world which should have that comment visible: https://lemmy.world/post/40374746

You’ll have to resolve my comment link on your instance since my instance is set to private now, but in case that doesn’t work, here’s the text of it:

So, I set this up recently and agree with all of your points about the actual integration being glossed over.

I already had bot detection setup in my Nginx config, so adding Nepenthes was just changing the behavior of that. Previously, I had just returned either 404 or 444 to those requests but now it redirects them to Nepenthes.

Rather than trying to do rewrites and pretend the Nepenthes content is under my app’s URL namespace, I just do a redirect which the bot crawlers tend to follow just fine.

There’s several parts to this to keep my config sane. Each of those are in include files.

• An include file that looks at the user agent, compares it to a list of bot UA regexes, and sets a variable to either 0 or 1. By itself, that include file doesn’t do anything more than set that variable. This allows me to have it as a global config without having it apply to every virtual host.

• An include file that performs the action if a variable is set to true. This has to be included in the server portion of each virtual host where I want the bot traffic to go to Nepenthes. If this isn’t included in a virtual host’s server block, then bot traffic is allowed.

• A virtual host where the Nepenthes content is presented. I run a subdomain (content.mydomain.xyz). You could also do this as a path off of your protected domain, but this works for me and keeps my already complex config from getting any worse. Plus, it was easier to integrate into my existing bot config. Had I not already had that, I would have run it off of a path (and may go back and do that when I have time to mess with it again).

The map-bot-user-agents.conf is included in the http section of Nginx and applies to all virtual hosts. You can either include this in the main nginx.conf or at the top (above the server section) in your individual virtual host config file(s).

The deny-disallowed.conf is included individually in each virtual hosts’s server section. Even though the bot detection is global, if the virtual host’s server section does not include the action file, then nothing is done.

    # This redirects them to the Nepenthes domain. So far, pretty much all the bot crawlers have been happy to accept the redirect and crawl the tarpit continuously

I was blocking them but decided to shunt their traffic to Nepenthes instead. There’s usually 3-4 different bots thrashing around in there at any given time.

If you have the resources, I highly recommend it.

Most of the requirements are going to be for the database, and that depends on:

1. How many active users you expect
2. How many large rooms you or your users join

I left many of the large Matrix spaces I was in, and mine is now mostly just 1:1 chats or a group chat with a handful of friends. Given that low-usage case, I can run my server on a Pi 3 with 4 GB of RAM quite comfortably. I don’t do that in practice, but I do have that setup as a backup server - it periodically syncs the database from my main server - and works fine. The bottleneck there, really, is the SD card storage since I didn’t want an external SSD hanging off of it.

Even when I was active in several large Matrix spaces/rooms, a USFF Optiplex with a quad core i5, 8 GB of RAM, and a 500GB SSD was more than enough to run it comfortably alongside some other services like LibreTranslate.

I disabled local thumbnail generation almost a year ago, and things mostly work the same.

Instead of a local thumbnail image URL for things like news articles that get posted, it will be the direct URL value from the og:image metadata from the source. Usually those load fine, but sometimes they don’t due to CORS settings on their side. Probably only 1-2% of posts have issues, though.

For image posts that come in via federation, (memes, pics, etc), the thumbnail image URL is the same as the post URL. In other words, you’re loading the full res version in the feed. Since I use a web client that has “card view”, this actually works out better, visually. YMMV whether that’s a drawback for you.

The only pitfall is that you will lose thumbnails for image posts if an instance goes offline or shuts down.

I’m sure that does increase load slightly on other instances, but no more than if the remote instance had image proxying turned on. And the full-res version always has to load from the remote instance (even if you have local thumbnail generation enabled). All in all, I’d say the additional load is acceptable given the benefits of disabling local thumbnail generation.

To mitigate that, in my case anyway, I have my own image proxy/cache in place. My default UI is Tesseract and it’s configured with the image proxy/cache on by default… (I think I saw that Photon is also working on something similar). In this configuration, the first person to scroll past a remote image fetches it directly (via the proxy/cache) and it’s now available locally in the cache for everyone else (unless they’re connecting with a different client that doesn’t use Tesseract’s proxy). Granted, I shutdown my instance last year and it’s just now a private testbed for development, but when I did have daily active users (plural), the proxy cache helped.

Now the only images my instance stores are ones that are uploaded locally.

Why did I disable local thumbnails?

• I closed up my instance and didn’t want potentially problematic thumbnails being generated while I wasn’t actively modding it
• Generated thumbnails go in, but they don’t go out. There’s no way to clean them up later other than the ephemerally generated ones (if someone requests a version in a custom size, for example)
• Increasing storage costs. Like, I’d be scrolling the feed and see some of the dumbest shitposts while constantly thinking “Ugh, this is costing me money to store a copy”.
