I'm going to set up a general purpose instance tomorrow with the intention of handling a relatively large number of users. The main problem is choosing a domain!

Naming things is one of the two most difficult issues in IT, alongside cache validation and off-by-one errors.
I'm getting the following error reading this post: "item at index 2 does not exist"
Should I post this on stack overflow or some other Lemmy help community?
Which frontend are you using?
I name everything as var1 var2 etc.
var37.social incoming
There are only two hard things in CS: naming things, caching, and off-by-one errors.
I already said that
Look at that, you sure did. I missed the “two hard things”. Wasn’t even drunk. 🤷
I was also contemplating setting up a new instance for this. I have 100s of gigs of unused ram, CPUs on idle and a 10gbit connection looking for something to do. The only issue I couldn't figure out was the name. I own itjust.works was thinking of something clever subdomain to use with it. I'm glad I'm not the only one with this issue
sh.itjust.works
I did it! https://sh.itjust.works
Credits go to you for the naming
Dude killer url, nice one! Question for all, I clicked their link and went there and it’s an instance, surely. I tried to comment on their post, but was required to sign in.. I’m already signed in over here, I gotta sign in there, too? Anyhow I tried to sign in with my lemmy.ml creds but that didn’t work. How can I interact with posts there?
Lol awesomesauce. I just made an account, I'll use it as my main instance for a while. Let's hope we can survive reddit hug of death 2.0 in July!
This is a great one! Might use it
Keep it simple with lemmy.itjust.works.
If you get this going or need a hand then let me know.
Do you also have a few million dollars under your mattress? 😁
I’d like to tell myself that if it got to the point where it started to cost a few million that i would be able to have it pay for itself!
It's a week later, but I did get this done finally. I've set up https://lem.monster/ . Still doing some tweaking, but it's open.
Point us to where the coin slot is. E.g. Patreon. We insert coin 🪙, you upgrade.
@nutomic@lemmy.ml It might be a good idea to default the Communities page to All instead of Local, to help push users into discovering other instances and promote them.
I think lemmy will be bitten in the ass by not having considered clustering/horizontal scaling from the start. Federation alone as a scaling mechanism is only feasible for "nerds". But if the network wants to grow, we will need a few scale-able large hosted instances. And if their only choice is to scale vertically, there will be a hard limit (unless we put a good old Mainframe somewhere ^^).
Another downside of this design is: you can't run it with high availability. If there's only one process per instance, updating it will mean the whole instance is down. Sure, if all goes well this downtime is under a second. But if it doesn't go well or if a migration is needed, this might quickly become hours.
Indeed. If a big instance like lemmy.ml was to be shut down all the communities would be lost. This is simply not sustainable. Why would users put effort building a community if it could be gone at any time?
That however would be a different problem. A horizontally scaled instance would be able to cope with more users, but if it shuts down for monetary, personal, or whatever reason, it's still down.
Protecting a community from this is what the decentralized part is for. That is already in place.
(Although there is a middle ground where you could design the system in a way that one instance is mirrored and load-balanced across different hosters. That would actually also be quite interesting to have. But that's another layer of complexity on top.)
Hi,
I setup my account on lemmy.ca. But it seems I cannot sign into lemmy.ml with this account (just getting busy spinning circle. On a high level I want to subscribe to some of the communities on lemmy.ml.
Thanks
After watching a video and looking around it looks like I was in error. Pretty much I can be signed into lemmy.ca ... then change he view filter to show all communities and subscribe to technology community on ML. The subscribe button does not always update right away. But in my listing of lemmy.ca I see I am subscribed. Hope this helps someone else.
Edit: If you moderate a large subreddit, do not link your users directly to lemmy.ml in your announcements
How/which URL should we link to then? Now is the best time to get users to switch to Lemmy so we need to make it as newbie friendly as possible. Already the application process has put off some people (I do like that bit though, keeps away the low effort folks). Thanks.
How/which URL should we link to then?
My (somewhat) hot take is that large migrating subreddits should probably host their own communities, which is what we did when we told people on r/PrivacyGuides to move to Lemmy. Or at the very least, actually coordinate with instance admins beforehand about all of this, clearly lemmy.ml isn't the ideal choice for this situation.
