An unmanaged switch is just a single plane where all ports are equal. All ports share OSI layers 1 and 2. Anything you plug into port 24 can always reach anything you have plugged into port 3.

Managed switches (also sometimes known as “smart” switches) provide additional features on top of that. The most useful is VLANs (virtual LANs) which let you segregate traffic. Two ports on different VLANs share the same physical layer (layer 1) but are separated at the data link layer (layer 2). This lets you create up to 4096 different networks on the same switch; each network is isolated from the other. If port 24 and port 3 are on different VLANs, then they will not be able to communicate unless they can reach a common router at layer 3.

Additionally, managed switches let you do things like disable/enable ports (for security, power savings, etc), enable port mirroring, and combine multiple ports into an aggregation group (e.g. bond four 1 Gb links into one 4 Gb link).

The available features on a managed/smart switch vary by manufacturer and, often, by the license level (sadly common in enterprise gear). VLANs, port control, mirroring, and LAGs are usually common “baseline” features, though.

Which begs the question why not magnets at the top of the building to help pull the electricity up?

Guess it depends on the height, but yeah. Otherwise, we manage to pump a town’s worth of water to the top of a tower well enough. From there, gravity can do the rest.

But there’s probably a point where cost for that vs height becomes prohibitive.

If the costs of engineering a tower is more than just buying more land, then why build taller?

Figured it’d be something like that. Explains why they get built out in the middle of nowhere since land is cheap.

Tall data centers do exist in cities where land is expensive.

Probably a bit of “hiding in plain sight” that way, too. There are a few big datacenters relatively near me, and they’re massive compounds in the middle of even more massive corn fields. Kind of stick out like a sore thumb when you’re driving by.

Modern Classic problems require modern solutions.

Yeah, I don’t know about pre-installed with Android that aren’t ad platforms masquerading as consumer hardware. I’d never use one unless it was supported by LineageOS or something. My comment was more “roll your own” in nature.

That person is giving me “I’m not touching you! I’m not touching you!” vibes. lol.

In a public park, you can absolutely ask random people to leave your party area. Not the park, but the space you are using. Double so if you’ve gone through the official channels to reserve that section.

And that goes both ways: If someone is having an event and one inserts themselves where they’re clearly not invited, then that person very much has issues respecting others’ boundaries.

It all boils down to people respecting each other.

I’ll take your word for it, though I assume it is the case. Like I said…it’s just the internet doing what it does (for better or worse).

“As an American” (though speaking only for myself) when I see those, I don’t even go into them because my opinion wasn’t solicited. I also don’t throw out my opinions in non-American news/politics communities for the same reason. Also, I wish that was a two-way street.

FWIW that community is just inspired by something that already exists outside of social media. The community owner kept !dull_mens_club@lemmy.world up since it’s pretty active, but the new official/recommended one for dull stuff is !Dullsters@dullsters.net . They explicitly wanted it to be more inclusive (not that DMC was only restricted to men posting).

It’s just…the internet I guess?

Go into the various “Ask” communities, and you’ll see things like this constantly:

Women of Lemmy, what’s something that…?

As a man, I …

Americans of Lemmy, what is your favorite…?

As a European, I…

Definitely mildly infuriating when people just butt in when they’re explicitly not the target audience of the question. If I’m somehow doing that with this reply, lol, I apologetically appreciate the irony.

Maybe one of those HDMI “stick” PCs you can get? There’s x86 Android builds you can run or you can do like I did with my media PCs and boot into Openbox and just launch a fullscreen browser right to Jellyfin and control it from your phone. (My main setup uses Emby but should be able to do the same with JF).

I’ve actually got a portable Jellyfin server I take with me. Built on the OrangePi Zero 2W with a USB->NVMe acting as media storage (as well as the Jellyfin DB). It’s got several other services running as well as a second Wifi adapter so it can also act as a travel router.

For playback, I pretty much just use my laptop or phone but have thought about adding one of the “stick” PCs as a client for it.

As a Trekkie, I’d be more mad about that ending than the series finale of ENT. And if the Xenomorph finale turned out to be a holodeck program, I would probably hate it even more lol.

Not throwing shade. As a standalone story or alternate continuity, Id totally read it. But I would be livid if it was the actual finale to TNG.

Also, Strange New Worlds kind of did that with the Gorn.

And you’re going to honestly believe a mod’s reasoning at face-value?

Irrelevant. As a literate human being, I can click on your username and see your submissions. I can search the alt they listed and read those submissions. And, finally, I can look at those and arrive at the conclusion that both of those seem like trolling and the same person.

Now that you’ve been sufficiently fed, I bid you adieu with my handy dandy block button.

You mean this post that’s not removed? https://kbin.melroy.org/m/unpopularopinion@lemmy.world/t/1316788

(Edit: Fixed wrong post link. That link was to this post 🤦)

Looks like a cromulent, albeit absolute shit, opinion to me. So far so good (using that phrase loosely). BUT… you seem to have behaved very asshole-ish in the comments.

And the modlog says Trolling and Ban Evasion and listed another alt with a similar post history to yours that was also banned for trolling and hasn’t posted since your account was created. 🤔

So, maybe instead of whinging you do some self reflection, yeah?

Yep, that’s why I haven’t messed with Kubernetes either; way overkill for a homelab and especially so since I downsized due to soaring electricity costs here.

The only reason I gave up on Docker Swarm was that it seemed pretty dead-end as far as being useful outside the homelab. At the time, it was still competing with Kubernetes, but Kube seems to have won out. I’m not even sure Docker CE even still has Swarm. It’s been a good while since I messed with it. It might be a “pro” feature nowadays.

Edit: Docker 28.5.2 still has Swarm.

Still, it was nice and a lot easier to use than Kubernetes once you wrapped your head around swarm networking.

I had 15 of the 2013-era 5010 thin clients. Most of them have had their SSDs and RAM upgraded.

They’ve worn many hats since I’ve had them, but some of their uses and proposed uses were:

1. I did a 15 node Docker Swarm setup and used that to both run some of my applications as well as learn how to do horizontal scaling.
2. After I tore down the Docker Swarm cluster, I set them up as diskless workstations to both learn how to do that and used them at a local event as web kiosks (basically just to have a bunch of stations people could use to fill out web based forms).
3. One of them was my router for a good while. Only replaced it in that role when I got symmetric gigabit fiber. Before that, I used VLANs to to run LAN and WAN over its single ethernet port since I had asymmetric 500 Mbps and never saturated the port.
4. Run small/lightweight applications in highly-available pairs/clusters
5. Use them to practice clustered services (Multi-master Galera/MariaDB, multi-master LDAP, CouchDB, etc)
6. Use them as Snapcast clients in each room
7. Add wireless cards, install OpenWRT, and make powerful access points for each room (can combine with the above and also be a Snapcast client)
8. Set them up as VPN tunnel endpoints, give them out to friends, and have a private network

Of the 15, I think I’m only actively using 4 nowadays. One is my MPD+Snapcast server, one is running HomeAssistant, ,the third is my backup LDAP server, and one runs my email server (really). The rest I just spin up as needed for various projects; I downsized my homelab and don’t have a lot of spare capacity for dev/test VMs these days, so these work great in place of that.
