They have fairly reasonable guides on their site on how to host for others.

Depends on what part of “set up” you’re referring to. Getting the software itself up and running is extremely easy. They have versions available for the full swathe of experience levels from “here is a packaged Electron based Windows application” to “here are the node.js source files”. All prior versions are also available if you have specific needs for an earlier version.

Now, if you mean how difficult is it to set up and run a game, that’s going to vary wildly depending on the system the game uses and how complex of a scenario whoever is running the game wants to deal with. There are lots of off-the-shelf one shots or campaigns you can run where that setup is already done for you though.

Couple of things I have running on my home server no one has mentioned yet.

FoundryVTT is a self-hostable platform for playing tabletop RPGs online. It supports a vast selection of game systems and user/community developed mods making it extremely versatile.

Pihole is probably something you’ve heard of before and despite the name is hostable on a wide variety of systems. In case you haven’t it’s a network level ad blocker that works by taking over the role of DNS server on your LAN and blocking queries to domains used to serve ads or track telemetry.

I would be ashamed of myself and be tempted to leave the industry in disgrace if setting up DDNS and allowing a single port through a firewall took me 45 minutes.

I won’t stand for this PowerShell superhero comic erasure.

Jellyfin has some security issues that, depending on who you ask, are either critical vulnerabilities that make it completely unsafe to expose to the Internet or largely unconcerning for regular users.

I had exactly the same experience, at about the same time. Had been hearing good things about Plex so decided to try it out. Immediately noped out when it required me to create an account with them. Similar to you I looked around and found it to be a relatively new change.

Frankly baffling to me that anyone with the wherewithal to self-host was okay with it.

OP doesn’t seem to have responded, so no, but that’s not the fault of the question.

Because of the XY problem. The problem OP is stating may not actually be the source of the issues OP is experiencing.

Finding out what OP is trying to do will better inform a solution and may make the stated problem irrelevant.

i is still a value type, that never changes. Which highlights another issue I have with the explanation as provided. Using the word “reference” in a confusing way. Anonymous methods capture their enclosing scope, so i simply remains in-scope for all calls to those functions, and all those functions share the same enclosing scope. It never changes from being a value type.

I think the explanation they provide is a bit lacking as well. Defining an anonymous function doesn’t “create a reference” to any variables it uses, it captures the scope in which it was defined and retains existing references.

The WTF in the C# example seems to be that people don’t understand anonymous functions and closures?

When I initially set up my media server I went with Jellyfin over Plex mostly because the idea of having to create an account on an external service to use software I was hosting myself rubbed me the wrong way. Since then the more learn about Plex the more baffled I am that anyone chooses to use it at all.

Even more ridiculous since a 1.4x performance increase is already incredible news for anyone who makes regular of this.

If someone found a software optimization that improved, say, blender performance by 1.4x people would be shouting praises from the rooftops.

I wouldn’t buy a new Seagate drive, let alone a refurbished one. Every Seagate I’ve ever owned died in less than five years. Every WD I’ve owned lasted until long after their capacity was so far outpaced by newer drives as to be useless.

Anecdotal, yes, but it’s happened enough to me that I’ve been soured on them for life.

For those of you who’ve never experienced the joy of PowerBuilder, this could often happen in their IDE due to debug mode actually altering the state of some variables.

More specifically, if you watched a variable or property then it would be initialised to a default value by the debugger if it didn’t already exist, so any errors that were happening due to null values/references would just magically stop.

Another fun one that made debugging difficult, “local” scoping is shared between multiple instances of the same event. So if you had, say, a mouse move event that fired ten times as the cursor transited a row and in that event you set something like integer li_current_x = xpos the most recent assignment would quash the value of li_current_x in every instance of that event that was currently executing.

There are a few options there.

As someone else mentioned if you’re using IPv6 then it doesn’t matter, you’re already routing internally even if you’re using the public DNS name, no extra work required.

All the rest are for IPv4.

If you’re not behind CGNAT some routers/gateways are also smart enough with their routing to recognise when they need to route back to their own external IP and will loop back locally instead of making any hops out to the internet. Again, if this is the case for you then no additional work is required other than perhaps running a traceroute to confirm.

Another option is to add a local DNS entry for the name you’re using to resolve to a local IP address instead of your public address. The complexity (or even possibility) of this is going to vary considerably with your setup. If you’re running your own local DNS e.g. pihole or similar then it’s trivial. This is how mine is set up.

If all your clients are going to be on PCs (or devices you have more than the typical manufacturer allowed modicum of control over) then you can do something kind of like the previous, just with all your local hosts files.

If none of the above are options, then you’ll unfortunately have to fall back on using a local name/address, which means a slightly different client setup for devices you use exclusively in your home versus ones you might use elsewhere.

Traffic for a local Jellyfin server should definitely not be going over the internet. Also any reasonably modern client should be able to direct play most media without transcoding.

As for my own Jellyfin setup, one TV has an Nvidia shield plugged in and is using the standard Android TV client. The other is a Samsung smart TV onto which I have side-loaded the Jellyfin Tizen app.

A temporary one that you’re expected to remove as soon as you’ve created the admin user(s) you need, but yes. It should only be there during initial setup and ideally removed before the server is ever exposed to the internet.

Neither of those points invalidate the idea presented.

Just because it’s not a uniform distribution doesn’t mean the average changes. Most people learning a thing earlier in life doesn’t change the average rate. Even if literally every single person learned a given fact on their ninth birthday, that still averages out to the same rate.

As for your second point, you’re conflating “things everyone knows” with “knowing everything”. Obviously people who are 80 still don’t know everything, but it’s not unreasonable to assume they share a pool of common knowledge most of which was accumulated in their early life.

And even if both of those things were valid criticisms, the thing you’re calling out as “inaccurate pseudoscience” is the suggestion that people shouldn’t be ridiculed for not knowing things, rather we should enjoy the opportunity to share knowledge.
