Another user posted the blog where they discuss their speedup techniques: https://tailscale.com/blog/more-throughput/

It’s likely that the kernel version can use similar techniques to surpass the performance of the userspace version that tailscale uses, but no one has put in the work to to make the kernel implementation as sophisticated as the userspace one.

For the latest version of lemmy, hot sort works in the new fashion. There is a pull request with further implementation details linked in the GitHub issue.

Ah, fair enough. My response doesn’t apply then.

You misunderstand what the Hot rank is doing. It’s not balancing newness vs hotness, it’s scaling hotness according to community size. This might feel like newness if you’re focused on vote counts as a proxy for post age, but it’s a different approach. See https://github.com/LemmyNet/lemmy/issues/3622 for details.

There’s a couple ways to think about this:

1. There are a handful of Lemmy communities that are just WAY more active than everything else. The main feeds are kind of lame if you have to scroll 300 posts it to find anything other than a shit post from the same 3 communities. Scaled Hot rank shows a greater variety of communities by making it easier small communities to get ranked hotly.
2. Or you can consider Hotness to be a rough measure of what percentage of people who have seen the post interacted with it. A post with 500 upvotes in a community with 10,000 active users is kind of popular, but only 5% of the people likely to have scrolled passed it cared about it. A post with 50 upvotes in a community with 200 active members is much MORE popular relatively even though the absolute numbers are smaller.

At any rate, this preference toward smaller communities in hot is a recent change and deliberate. While they might further tweak the scaling factors, I wouldn’t expect it to be drastically different. It sounds to me like what you want is Top, Active, or Most Comments. All these are unscaled according to community size and will get you top posts by their absolute metric rather than posts that are doing well relative to their community size.

I dunno how to hotlink, but if you scroll to the active users graph at https://fedidb.org/software/lemmy you can see there’s been like a 25% dropoff in active users since the peak in July. Lemmy has still grown 50x since May, and it’s much MUCH more active than it was then. But we’ve definitely crested a peak and not everyone who gave Lemmy a shot then is sticking around in a monthly basis.

This isn’t necessarily bad. Lemmy is still young and has many rough edges, it wasn’t realistic to win all the users that tried it on ease-of-use in a head to head with reddit. And Mastodon has had multiple growth waves interspersed with periods of declining usage, but with the spikes has grown ie remained stable overall. Early-stage commercial social media have big ups and downs in engagement and growth as well, and just like lemmy those ups and downs are often externally driven… when competitors mess up, when a big global news story hits, when a major sporting event happens… these can all be catalysts for one-time growth. It’s not a straight line.

Time will tell what user level we stabilize at in the short-term and what events spur new growth, but it’s normal to have a big expansion be followed by some degree of contraction.

No no, sorry. I mean can I still have all my network traffic go through some VPN service (mine or a providers) while Tailscale is activated?

Tailscale just partnered with Mullvad so this works out of the box for that setup: https://tailscale.com/blog/mullvad-integration/

For others, it’s a “yes on paper” situation. It will probably often not work out of the box, but it seems likely to be possible as an advanced configuration. At the end of the line of possibilities, it would definitely be possible to set up a couple of docker containers as one-armed routers, one with your VPN and one with Tailscale as an exit node. Then they can each have their own networking stack and you can set up your own routes and DNS delegating only the necessary bits to each one. That’s a pretty advanced setup and you may not have the knowhow for it, but it demonstrates what’s possible.

To a first approximation, Tailscale/Headscale don’t route and traffic.

Ah, well damn. Is there a way to achieve this while using Tailscale as well, or is that even recommended?

Is there a way to achieve what? Force tailscale to route all traffic through the DERP servers? I don’t know, and I don’t know why you’d want to. When my laptop is at home on the same network as my file-server, I certainly don’t want tailscale sending filserver traffic out to my Headscale server on the Internet just to download it back to my laptop on the same network it came from. I want NAT traversal to allow my laptop and file-server to negotiate the most efficient network path that works for them… whether that’s within my home lab when I’m there, across the internet when I’m traveling, or routing through the DERP server when no other option works.

OpenVPN or vanilla Wireguard are commonly setup with simple hub-and-spoke routing topologies that send all VPN traffic through “the VPN server”, but this is generally slower path than a direct connection. It might be imperceptibly slower over the Internet, but it will be MUCH slower than the local network unless you do some split-dns shenanigans to special-case the local-network scenario. With Tailscale, it all more or less works the same wherever you are which is a big benefit. Of course excepting if you have a true multigigabit network at home and the encryption overhead slows you down… Wireguard is pretty fast though and not a problematic throughout limiter for the vast majority of cases.

Have a read through https://tailscale.com/blog/how-nat-traversal-works/

You, and many commenters are pretty confused about out tailscale/Headscale work.

1. To a first approximation, Tailscale/Headscale don’t route and traffic. They perform NAT traversal and data flows directly between nodes on the tailnet, without traversing Headscale/Tailscale directly.
2. If NAT traversal fails badly enough, it’s POSSIBLE that bulk traffic can flow through the headscale/tailscale DERP nodes… but that’s an unusual scenario.
3. You probably can’t run Headscale from your home network and have it perform the NAT traversal functions correctly. Of course, I can’t know that for sure because I don’t know anything about your ISP… but home ISPs preventing Headscale from doing it’s NAT traversal job are the norm… one would be pleasantly surprised to find that a home network can do that properly.
4. Are younreally expecting 10gb/s speeds over your encrypted links? I don’t want to say it’s impossible, people do it… but you’d generally only expect to see this on fairly burly servers that are properly configured. Tailscale just in April bragged about hitting 10gb speeds with recent optimizations: https://tailscale.com/blog/more-throughput/ and on home hardware with novice configd I’d generally expect to see roughly more like single gigabit.

So I have a question, what can I do to prevent that from happening? Apart from hosting everything on my own hardware of course, for now I prefer to use VPS for different reasons.

Others have mentioned that client-caching can act as a read-only stopgap while you restore Vaultwarden.

But otherwise the solution is backup/restore. If you run Vaultwarden in docker or podman container using volumes to hold state… then you know that as long as you can restart Vaultwarden without losing data that you also know exactly what data needs to be backed up and what needs to be done to restore it. Set up a nightly cron job somewhere (your laptop is fine enough if you don’t have somewhere better) to shut down Vaultwarden, rsync it’s volume dirs, and start it up again. If you VPS explodes, copy these directories to a new VPS at the same DNS name and restart Vaultwarden using the same podman or docker-compose setup.

All that said, keeypass+filesync is a great solution as well. The reason I moved to Vaultwarden was so I could share passwords with others in a controlled way. For single-user, I prefer how keypass folders work and keepass generally has better organization features… I’d still be using it for only myself.

My take echoes this. If one puts any stock in streamer recommendations, Baalorlord who has at various times held spire world record winstreaks, has recently cited Monster Train as his current favorite spirelike (other than spire itself), and also cited Griftlands as a playthrough a highlight.

Baalor probably doesn’t have an opinion on Inscryption as he tends to avoid things with even a slight horror theme. I enjoyed what I played of Inscryption a lot, but very little about playing it evoked the vibe of playing spire. Monster Train is quite adjacent though, the mechanics are different enough to feel fresh but it slots into the same gameplay mood for me whereas Inscryption is just a different (and still very good) thing.

Neither has the tight balance of Spire or feels quite as deep strategically to me (though in all honesty I’m probably not a strong enough player to be trusted in this regard), but both are fun.

That’s an interesting report but it’s possible to “work” at different latencies. And unless you have specialized audio capture/playback hardware and have done some tuning and testing to determine the lowest stable latency that your system is capable of achieving… “works” for you is likely to mean something very different than it does to someone who does a lot of music production.

It remains an interesting question to some users whether Wayland changes the minimum stable latency relative to X and if so whether it does so for better or worse.

I’d consider asking in a Linux audio or music production community (I’m not aware of any on Lemmy that are big enough to have a likely answer though). If music production is a primary use case and audio latency matters to you, almost no general users are going to be able to comment on the difference between X and Wayland from a latency perspective. There may not be a difference, but there might and you won’t be likely to learn about it outside of an audio-focused discussion.

It may seem kinda stupid to consider that an accomplishment, but I feel quite genuinely proud of myself for actually succeeding at this instead of just throwing in the towel…

Way to go. I’ve been at this a decent while and do some pretty esoteric stuff at work and at home… but this loop of feeling stupid, doing the work, and feeling good about a success has been a constant throughout. I spent a week struggling to port some advanced container setups to podman a month or so ago, same feeling of pride when I got them humming.

It’s not stupid to be proud of an accomplishment even if it’s a fundamental one that’s early in a bigger learning curve. Soak it in, then on to the next high. Good luck.

I use Headscale, but Tailscale is a great service and what I generally recommend to strangers who want to approximate my setup. The tradeoffs are pretty straightforward:

• Tailscale is going to have better uptime than any single-machine Headscale setup, though not better uptime than the single-machine services I use it to access… so not a big deal to me either way.
• Tailscale doesn’t require you to wrestle with certs or the networking setup required to do NAT traversal. And they do it well, you don’t have to wonder whether you’ve screwed something up that’s degrading NAT traversal only in certain conditions. It just works. That said, I’ve been through the wringer already on these topics so Headscale is not painful for me.
• Headscale is self-hosted, for better and worse.
• In the default config (and in any reasonable user-friendly, non professional config), Tailscale can inject a node into your network. They don’t and won’t. They can’t sniff your traffic without adding a node to your tailnet. But they do have the technical capability to join a node to your tailnet without your consent… their policy to not do that protects you… but their technology doesn’t. This isn’t some surveillance power grab though, it’s a risk that’s essential to the service they provide… which is determining what nodes can join your tailnet. IMO, the tailscale security architecture is strong. I’d have no qualms about trusting them with my network.
• Beyond 3 devices users, Tailscale costs money… about $6 US in that geography. It’s a pretty reasonable cost for the service, and proportional in the grand scheme of what most self-hosters spend on their setups annually. IMO, it’s good value and I wouldn’t feel bad paying it.

Tailscale is great, and there’s no compelling reason that should prevent most self-hosters that want it from using it. I use Headscale because I can and I’m comfortable doing so… But they’re both awesome options.

Tailscale is out, unfortunately. Because the server also runs Plex and I need to use it with Chromecast on remote access…

I rather suspect you already understand this, but for anyone following along… Tailscale can be combined with other networking techniques as well. So one could:

• Access Plex from a Chromecast on your home network using your physical IP, and on your tailnet using the overlay IP.
• Or one could have some services exposed publicly and others exposed on the tailnet. So Immich could be on the tailnet while Plex is exposed differently.

It’s not an all or nothing proposition, but of course the more networking components you have the more complicated everything gets. If one can simplify, it’s often well worth doing so.

Good luck, however you approach it.

So for something like Jellyfin that you are sharing to multiple people you would suggest a VPS running a reverse proxy instead of using DDNS and port forwarding to expose your home IP?

I run my Jellyfin on Tailscale and don’t expose it directly to the internet. This limits remote access to my own devices, or the devices of those I’m willing to help install and configure tailscale on. I don’t really trust Jellyfin on the public internet though. It’s both a bit buggy, which doesn’t bode well for security posture… and also a misconfiguration that exposes your content could generate a lot of copyright liability even if it’s all legitimately licensed since you’re not allowed to redistribute it.

But if you do want it publicly accessible there isn’t a hoge difference between a VPS proxying and a dynamic DNS setup. I have a VPS and like it, but there’s nothing I do with it that couldn’t be done with Cloudflare tunnel or dyndns.

What VPS would you recommend? I would prefer to self host, but if that is too large of a security concern I think there is a real argument for a VPS.

I use linode, or what used to be linode before it was acquired by Akamai. Vultr and Digitalocean are probably what I’d look to if I got dissatisfied. There’s a lot of good options available. I don’t see a VPS proxy as a security improvement over Cloudflare tunnel or dyndns though. Tailscale is the security improvement that matters to me, by removing public internet access to a service entirely, while lettinge continue to use it from my devices.

Do I need to set up NGINX on a VPS (or similar cloud based server) to send the queries to my home box?

A proxy on a VPS is one way to do this, but not the only way and not necessarily the best one… depending on your goals.

• You can also use port-forwarding and dyndns to just expose the port off your home-ip. If your ISP is sucky, this may not work though.
• You can also use Cloudflare’s free tunneling product, which is basically a hosted proxy that acts like a super port-forward that bypasses sucky ISP restrictions.
• If you want to access Immich yourself from your own devices but don’t need to make it available to (many) others on devices you don’t control, I like and use tailscale the best. The advantage of tailscale is that Immich remains on a private network, not directly scannable from the internet. If there’s a preauth exploit published and you don’t pay attention to update promptly, scanners WILL exploit your Immich instance with internet-exposed techniques… whereas tailscale allows you to access services that internet scanners cannot connect to, which is a nice safety net.

Do I need to purchase a domain (randomblahblah.xyz) to use as the main access route from outside my house?

Not for tailscale, and I don’t think for Cloudflare tunnel. Yes for a VPS proxy.

I’ve run a VPS for a long while and use multiple techniques for different services.

• Some services I run directly on the VPS because it’s simple and I want them to be truly publicly accessible.
• Other services I run on a bigger server at home and proxy through the VPS because although I want them to be publicly accessible, they require more resources than my VPS has available. When I get around to installing Immich, there’s a decent chance it will go into this category.
• Still other services, I run wherever and attach them to my tailnet. These I access myself on my own devices (or maybe invite a handful of trusted people into my tailnet), but aren’t visible to the public internet. If I decide not to use immich’s shared gallery features (and so don’t need it publicly accessible) or decide I don’t trust it security-wise… it will go here instead of the proxy-by-vps category.

I use k8s at work and have built a k8s cluster in my homelab… but I did not like it. I tore it down, and currently using podman, and don’t think I would go back to k8s (though I would definitely use docker as an alternative to podman and would probably even recommend it over podman for beginners even though I’ve settled on podman for myself).

1. K8s itself is quite resource-consuming, especially on ram. My homelab is built on old/junk hardware from retired workstations. I don’t want the kubelet itself sucking up half my ram. Things like k3s help with this considerably, but that’s not quite precisely k8s either. If I’m going to start trimming off the parts of k8s I don’t need, I end up going all the way to single-node podman/docker… not the halfway point that is k3s.
2. If you don’t use hostNetworking, the k8s model of traffic routes only with the cluster except for egress is all pure overhead. It’s totally necessary with you have a thousand engineers slinging services around your cluster, but there’s no benefit to this level fo rigor in service management in a homelab. Here again, the networking in podman/docker is more straightforward and maps better to the stuff I want to do in my homelab.
3. Podman accepts a subset of k8s resource-yaml as a docker-compose-like config interface. This lets me use my familiarity with k8s configs iny podman setup.

Overall, the simplicity and lightweight resource consumption of podman/docker are are what I value at home. The extra layers of abstraction and constraints k8s employs are valuable at work, where we have a lot of machines and alot of people that must coordinate effectively… but I don’t have those problems at home and the overhead (compute overhead, conceptual overhead, and config-overhesd) of k8s’ solutions to them is annoying there.

11,263 lbs, huh? It’s not a kind estimate, but not unrealistic either.

No, Beehaw defederated your instance. The open-source community on lemmy.ml someone else already mentioned is your best bet.
