I'll start: 39/M/US, so yeah, I fit the demographic.

29
A/S/L (lemmy.world)
 

To me, it seems like most of Lemmy consists of users who are older millennials (born at some point in the 80s), male, and about 50/50 split between living in North America or the EU.

Do you fit this demographic?

I have never really considered Lemmy or Reddit to be "social media." They're entirely anonymous, and you're not being exposed to posts where a apecific person is talking about themselves (at least for the most part). I think a modern equivalent to a PhpBB forum or (if you're old) a BBS is more accurate.

It's actually surprising how much just having a person in the room can alter the temperature and humidity levels. In my master bathroom, I have my bathroom fan set to activate when the dew point reaches a certain level (I've found that dew point produces better results than just humidity); the idea is that the bathroom will be ventilated when someone takes a shower and for however long it takes for the humidity to dissipate after they're done. The funny thing is that every so often, I'll take an excessively long poop (lets me honest, I'm scrolling on my phone), and the fan will kick on. Just being in the bathroom will alter the dew point enough that it triggers the fan.

I also have a room that contains all my server/networking equipment. It's climate-controlled, and I'm constantly monitoring temperatures. The times that in the room working, I can see a noticeable spike in the temperature graph, even though the only variable that's changed is that there's a person in the room.

So my point is: OP might not have been having fun that night; it's entirely possible someone just came in and went to bed.

In the first photo, the owl has a shadow over his left eye, and the pupil is larger than the right. Do their pupils dilate independently of one another, or is this the unfortunate result of brain trauma? If it's natural, that's a really cool adaptation.

As an undecided voter, the Democrats picked too expensive of a restaurant, so I'll have what the Republicans are having, even though it's moldy dog food.

(Edit: This is meant to be sarcastic and insulting to those who voted for Trump "because of the economy" if it's not obvious already, not to imply I was actually stupid enough to do that myself.)

Based on this reply, I get the distinct impression that you know a LOT more about networking than your original ELI5 post lets on, and almost certainly more about the subject than I. I work in tech, but not with networking specifically; most of my knowledge is from way too many years and dollars spent on homelabbing.

One of my internet connections is a DSL connection; by default, they provide a single IPv4 address. My DSL modem has an option to enable IPv6 tunneling through IPv4, but I was never able to get it to work, and customer support was completely clueless. I suspect this isn't something their network supports and they're just counting on their users not caring. My other connection is over satellite (Starlink), and as far as I am aware, they're only providing a single IPv6 connection, not a block of addresses.

To make things easy, I've just blocked IPv6 at my firewall, and I use policy-based routing on my PFsense box to send traffic to either connection depending on latency/bandwidth requirements (Streaming goes to satellite, VoIP goes to DSL, etc). I know that IPv6 has improvements beyond just "more addresses," but at this point I can't really justify enabling it on my network. It would only be used internally, and I just don't see any tangible benefit.

Really? Just out of curiosity, what kind of connection are you on? I have two ISPs, one of which provides a single IPv4 address only, and the other provides one IPv4 and one IPv6 address.

[–] [email protected] 2 points 6 days ago (5 children)

This is getting out of ELI5 territory, but the way it works with IPv4 is when something on the internet needs to access your devices, it sends a request to your IP address (your house) along with a port number. Your router (that runs your firewall) decides if it should forward the request to the device inside your network. By default, it usually says "no" unless you tell it otherwise.

With IPv6, you'd still have a router, most likely, but it would be "watching" all of the IP addresses for your devices, not just a single one for your entire home.

This does add a fair bit of complexity, but my guess is that if we ever do start getting blocks of IPv6 addresses as home users, most routers will probably come with default firewall blocking rules pre-configured.

[–] [email protected] 14 points 6 days ago* (last edited 6 days ago) (11 children)

IPv6 has several changes to the specification, but since this is ELI5:

When you were a child, your friends would call your house and a parent would answer the phone. They'd ask to talk to you, and your parents would hand the phone off to you. That might have been because you were too young to have a phone, but IPv4 with NAT works the same way because there are so many "houses" and only enough phone numbers for the houses, not all the people that live in them.

For IPv6 it's like your friends can call you directly on your cell phone. And they can call your brothers and sisters, your cat, your dog, your TV, your refrigerator, and the backyard squirrels. There are so many phone numbers that everyone can have their own.

The article didn't specify how old the affected models are, but any time you use an all-in-one device with proprietary software, you take the risk of this happening.

To some extent, you can't really blame the manufacturers for this, either. They can't reasonably continue maintaining software for their products for an indefinite period of time. As an extreme example, I wouldn't expect the old Linksys wifi router I used in 2004 to still be receiving firmware updates.

My NAS hardware is relatively ancient, but it's regular server hardware running TrueNAS. If TrueNAS suddenly stops getting updates, there's UnRaid, or just Linux. It really goes to show the advantage of using generic hardware with open software.

I'm very far away from "young," but I was once. Even in my early 20s, this would have seemed terrible. Sure, you have access to an interesting city, but you have no space for anything you can call your own. Even a rented studio anywhere else gives you somewhere to have a home you can call yours.

 

At least in this post, I'm not advocating for any particular political position; I mean for this to be a more generalized discussion.

I have never understood what prompts people to attend political rallies. None of the current US political candidates 100% align with my views, but I am very confident that I made the right choice in who I voted for. That is to say, I'd consider myself a strong supporter of [name here].

To me, it feels like attending a political rally is like attending a college lecture. You have a person giving you information, but you don't gain anything by hearing it in-person as opposed to reading it or watching a recording. If I want to learn something, it's much more comfortable for me to read and article or watch a video in the comfort of my own home. If I want to understand what a political candidate stands for, I'd much rather watch a recording of a town-hall meeting or read something she (oops) wrote rather than taking the time to drive to a rally, get packed in with a bunch of other people, and simply stand and listen.

I understand concerts. Hearing live music sounds vastly different than listening to a recording. Same with movies; most of us don't have an IMAX theater at home. When you're trying to gather information, though, what's the draw in standing outside in a crowd at listening to it in person?

 

This is more "home networking" than "homelab," but I imagine the people here might be familiar with what in talking about.

I'm trying to understand the logic behind ISPs offering asymmetrical connections. From a usage standpoint, the vast majority of traffic goes to the end-user instead of from the end-user. From a technical standpoint, though, it seems like it would be more difficult and more expensive to offer an asymmetrical connection.

While consumers may be connected via fiber, cable, DSL, etc, I assume that the ISP has a number of fiber links to "the internet." Those links are almost surely some symmetrical standard (maybe 40 or 100Gb). So if they assume that they can support 1000 users at a certain download speed, what is the advantage of limiting the upload? If their incoming trunks can support 1000 users at 100Mb download, shouldn't it also support 1000 users at 100Mb upload since the trunks themselves are symmetrical?

Limiting the upload speed to a different rate than download seems like it would just add a layer of complexity. I don't see a financial benefit either; if their links are already saturated for download, reducing upload speed doesn't help them add additional users. Upload bandwidth doesn't magically turn into download bandwidth.

Obviously there's some reason for this, but I can't think of one.

 

I generally try to stay informed on current events. With the exception of what gets posted here, I normally get my news from CNN. I tend to lean left politically, but not always.

The problem I always run into is that every news site I read, regardless of where they stand on the political spectrum, is always filled with pointless bullshit. Specifically, sports, celebrity news, and product placement. "Some shitty pop singer is dating some shitty actor" or "These are our recommendations for the best mass-produced garbage-quality fast fashion from Temu" or "Some overpaid dickhead threw a ball faster than some other overpaid dickhead."

What I'd love to find is a news source that's just news that matters. No celebrity gossip, sports, opinion pieces, etc. Just real events that have an impact on some part of the world. Legislation, natural events, economic changes, wars, political changes, that kind of thing.

Does this exist, or is all journalism just entertainment?

 

A few months ago, I upgraded all my network switches. I have a 16-port SFP+ switch and a 1GB switch (LAGG to the SPF+ with two DACs). These work perfectly, and I'm really happy with the setup so far.

My main switch ties into a remote switch in another building over a 10Gb fiber line, and this switch ties into another switch of the same model (on a different floor) over a Cat6e cable. These switches are absolute garbage: https://www.amazon.com/gp/product/B084MH9P8Q

I should have known better than to buy a cheap off-brand switch, but I had hoped that Zyxel was a decent enough brand that I'd be okay. Well, you get what you pay for, and that's $360 down the toilett. I constantly have dropped connections, generally resulting in any attached devices completely losing network connectivity, or if I'm lucky, dropping down to dial-up speeds (I'm not exaggerating). The only way to fix it is to pull the power cable to the switch. Even under virtually no load, the switch gets so hot that it's painful to touch. Judging from the fact that my connection is far more stable when the switch is sitting directly in front of an air conditioner, that tells me just about all I need to know.

I'm trying to find a pair of replacement switches, but I'm really striking out. I have two ancient Dell PowerConnect switches that are rock solid, but they're massive, they sound like jet engines, and they use a huge amount of power. Since these are remote from my homelab and live in occupied areas, they just won't work. All I need is a switch that has:

  • At least 2 SFP+ ports (or 1 SFP+ port for fiber and a 10Gb copper port)
  • At least 4 1Gb ports (or SFP ports; I have a pile of old 1GB SFP adapters)
  • Management/VLAN capability Everything I find online is either Chinese white-label junk or is much larger than what I need. A 16-port SFP+ switch would work, but I'd never use most of the ports, and I'd be wasting a lot of money on overkill hardware. As an example, one of these switches is in my home office; it exists solely so I have a connection between my server rack, two PCs, and a single WAP. I am never going to need another LAN connection in my home office; any hardware is going to go in the server rack, but I do need 10GB connectivity on at least one of those PCs.

Does anyone have a suggestion for a small reliable switch that has a few SFP+ ports, is made by a reputable brand, and isn't a fire hazard?

 

I have been using the BlueIris NVR integration (from HACS) for quite some time, and it works great for triggering BI from HA. I've trying to do the opposite now: Fire off automations in HA whenever BI detects motion on one of my cameras.

I've never used MQTT before, so I'm learning as I go, but I think I have most of my setup configured properly. I've installed Mosquitto and the MQTT integration in HA. I've configured BI to connect to HA, and running "Test" in the "Edit MQTT Server" menu in BI shows a good connection and no errors. I've set my cameras to post an MQTT event when the alert is triggered (and I've verified that the alerts are in fact being triggered).

Nothing happens in HA, though. The "Motion" sensor for my camera in HA stays at "Clear." In fact, the history shows no change at all, ever.

I have the events in BI set up as follows: On Alert: MQTT Topic - BlueIris/&CAM/Status and Payload - { "type": "&TYPE", "trigger": "ON" } On Reset: Exactly the same, but change ON to OFF.

I've tried change the MQTT autodiscovery header in HA from "homeassistant" to "BlueIris," and it made no difference. The Mosquitto logs show a login from HA, so I feel like I'm close, but I'm not sure where else to look.

Edit: I installed MQTT explorer, and I've verified that the messages are making it to Mosquitto, and they appear to be correctly formatted.

UPDATE: I set the MQTT integration to listen to the MQTT messages coming from BI, and sure enough, they were coming through just fine. For some reason, the BI integration just wasn't seeing them. Digging through the system logs, I saw some errors "creating a binary sensor" coming from the BI integration. The only thing I can think is that because I didn't have MQTT set up when I first installed the BI integration, something went wrong with the config (although I had already rebooted the system several times). I re-downloaded the BI integration and re-installed it, and now everything works perfectly.

 

This isn't strictly "homelab" related, but I'm not sure if there's a better community to post it.

I'm curious what kind of real-world speeds everyone is getting over their wireless network. I was testing tonight, and I'm getting a max of 250Mbit down/up on my laptop. I have 4 Unifi APs, each set to 802.11ac/80Mhz, and my laptop supports 2x2 MIMO. Testing on my phone (Galaxy S23) gives basically the exact same result.

The radio spectrum around me is ideal for WiFi; on 5Ghz, there is no AP in close enough range for me to detect. With an 80Mhz channel width, I can space all 4 of my APs so that there's no interference (using a non-DFS channel for testing, btw).

Am I wasting my time trying to chase higher speeds with my current setup? What kind of speeds are you getting on your WiFi network?

 

I've noticed recently that my network speed isn't what I would expect from a 10Gb network. For reference, I have a Proxmox server and a TrueNAS server, both connected to my primary switch with DAC. I've tested the speed by transferring files from the NAS with SMB and by using OpenSpeedTest running on a VM in Proxmox.

So far, this is what my testing has shown:

  • Using a Windows PC connected directly to my primary switch with CAT6: OpenSpeedTest shows around 2.5-3Gb to Proxmox, which is much slower than I'd expect. Transferring a file from my NAS hits a max of around 700-800MB (bytes, not bits), which is about what I'd expect given hard drive speed and overhead.
  • Using a Windows VM on Proxmox: OpenSpeedTest shows around 1.5-2Gb, which is much slower than I would expect. I'm using VirtIO network drivers, so I should realistically only be limited by CPU; it's all running internally in Proxmox. Transferring a file from my NAS hits a max of around 200-300MB, which is still unacceptably slow, even given the HDD bottleneck and SMB overhead.

The summary I get from this is:

  • The slowest transfer rate is between two VMs on my Proxmox server. This should be the fastest transfer rate.
  • Transferring from a VM to a bare-metal PC is significantly slower than expected, but better than between VMs.
  • Transferring from my NAS to a VM is faster than between two VMs, but still slower than it should be.
  • Transferring from my NAS to a bare-metal PC gives me the speeds I would expect.

Ultimately, this shows that the bottleneck is Proxmox. The more VMs involved in the transfer, the slower it gets. I'm not really sure where to look next, though. Is there a setting in Proxmox I should be looking at? My server is old (two Xeon 2650v2); is it just too slow to pass the data across the Linux network bridge at an acceptable rate? CPU usage on the VMs themselves doesn't get past 60% or so, but maybe Proxmox itself is CPU-bound?

The bulk of my network traffic is coming in-and-out of the VMs on Proxmox, so it's important that I figure this out. Any suggestions for testing or for a fix are very much appreciated.

 

I'm looking for a portable air conditioner (the kind with 1 or 2 hoses that go to outside air). The problem I'm running into is that every single one I find has some kind of "smart" controller built in. The ones with no WiFi connectivity still have buttons to start/stop the AC, meaning that a simple Zigbee outlet switch won't work. I could switch the AC off, but it would require a button-press to switch it back on. The ones with WiFi connectivity all require "cloud" access; my IoT devices all connect to a VLAN with no internet access, and I plan to keep it that way.

I suppose I could hack a relay in place of the "start" button, but I'd really rather just have something I can plug in and use.

I can't use a window AC; the room has no windows. I'll need to route intake/exhaust through the wall. So far, I can't find any "portable" AC that will work for me.

What I'm looking for is a portable AC that either:

  • Connects to WiFi and integrates with HA locally.
  • Has no connectivity but uses "dumb" controls so I can switch it with a Zigbee outlet switch.

Any ideas?

 

Yesterday, Brian Dorsey was executed for a crime he committed in 2006. By all accounts, during his time in prison, he became remorseful for his actions and was a "model prisoner," to the point that multiple corrections officers backed his petition for clemency.

https://www.cnn.com/2024/04/09/us/brian-dorsey-missouri-execution-tuesday/index.html

In general, the media is painting him as the victim of a justice system that fails to recognize rehabilitation. I find this idea disgusting. Brian Dorsey, in a drug-induced stupor, murdered the people who gave him shelter. He brutally ended the life of a woman and her husband, and (allegedly) sexually assaulted her corpse. There is an argument that he had ineffective legal representation, but that doesn't negate the fact that he is guilty.

While I do believe that he could have been released or had his sentence converted to life in prison, and he could have potentially been a model citizen, this would have been a perversion of justice. Actions that someone takes after committing a barbaric act do not undo the damage that was done. Those two individuals are still dead, and he needed to face the ramifications for his actions.

Rehabilitation should not be an option for someone who committed crimes as depraved as he did. Quite frankly, a lethal injection was far less than what he deserved, given the horror he inflicted on others. If the punishment should fit the crime, then he was given far more leniency than was warranted.

 

I just set up a local instance of Invidious. I created an account, exported my YouTube subscriptions, and imported them into Invidious. The first time I tried, it imported 5 subscriptions out of 50 or so. The second time I tried, it imported 9.

Thinking there might be a problem with the import function, I decided to manually add each subscription. Every time I click "Subscribe," the button will switch to "Unsubscribe," then immediately switch back to "Subscribe." If I look at my subscriptions, it was never added.

My first thought was a problem with the PostgreSQL database, but that wouldn't explain why some subscriptions work when I import them.

I tried rebooting the container, and it made no difference. I'm running Invidious in a Ubuntu 22.04 LXC container in Proxmox. I installed it manually (not with Docker). It has 100GB of HDD space, 4 CPU cores, and 8GB of memory.

What the hell is going on?

As is stands, parents are able to claim their children as dependents on their tax returns, which lowers their overall tax liability and in effect means that the parents either pay less in taxes or receive a higher return at the end of each year.

Until they reach the age at which they can work, children are a drain on society. They receive public schooling and receive the same benefit from public services that adults do, yet they contribute nothing in return. At the point that they reach maturity and are gainfully employed and paying taxes, they become a functioning member of society.

If a parent decides to have a child, they are making a conscious decision to produce another human being. They could choose to get a sterilization surgery, use birth control, or abort the pregnancy (assuming they don't live in a backwards state that's banned it). Yet even if they decide to have 15 children, the rest of society has to foot the bill for their poor decisions until the child reaches adulthood.

By increasing taxes on parents instead of reducing them, you not only incentivize safe sex and abortion, but you shift the burden of raising a child solely to the individuals who are responsible for the fact that that child exists.

I am a strong advocate for social programs: Single-payer healthcare, welfare programs, low-income housing, etc, but for adults who in turn contribute what they can. A child should only be supported by the individuals who created it.
