OPNSense is generally pretty easy, more powerful, and more open than pfsense. I started with pf but went to OPNSense and have loved it!

Honestly, I found it really easy. I don't have a background in IT or anything either.

What did you find difficult? Setting custom firewall rules is harder to understand, but the general functionality of setting up a NAT and even installing and configuring ZenArmor were super super easy.

There are mumble -> matrix bridges you can set up. It doesn't integrate with element, it integrates with matrix, for which matrix is a client.

Are you sure that docker is configured properly? What do you see if you do docker ps

Boom. tar --help for anyone wondering

Mirror all data on NAS A to NAS B

I'm duplicating my server hardware and moving the second set off site. I want to keep the data live since the whole system will be load balanced with my on site system. I've contemplated tools like syncthing to make a 1 to 1 copy of the data to NAS B but i know there has to be a better way. What have you used successfully?

doctorzeromd ,

That won't keep it constantly in sync though

doctorzeromd ,

Yes, do as I say!

There's a quick start script to install home assistant after you've set up proxmox. I've been running it with no issues for months

Why not?

Ahh got it. My search history says I read the follow up, but not the initial article.

That's ridiculous and unsettling, especially that they claimed it wasn't possible initially. I wonder if they were not aware that it was possible or whether they were lying. I'm not sure which one is worse.

I have a eufy doorbell cam, and I'm genuinely very happy with it. Since it's not actually looking into my home I'm less concerned about this particular security issue. I hope they do better moving forward.

I work in audio and had a thesis in DSP, so I'll try to explain this. It is an interesting idea, and in some cases could work, but wouldn't be practically useful in most.

So there's 2 types of audio encoding: Lossy and Lossless. All audio starts as lossless, and in many cases is converted to lossy to reduce the file size. The processing for this is NOT like compression, and is somewhat context aware in that it removes frequencies you wouldn't hear because something else is more present and causing your ear not to really hear it (this is called masking).

If you were to upscale something that is lossless, it would probably work. Barring any inter sample peaks, you'd be inferring additional points in a waveform and that's fine. They're actually some audio plugins that do this as an intermediate step when processing a signal.

If you try to upscale something that is lossy, you can't recreate what was removed, because there isn't a way to infer that information anymore. It would be like if you were trying to upscale a photo but you'd already removed a dog that was somewhat obscured by a man's hand. Even if you upscale the picture you can't add the dog without somebody telling you that it was there before removal.

The other part of the equation is "why?", and while I'm a bit of an audiophile and I have my collection of lossless audio, the limitations of the system are typically the human ear. CD quality, (16-bit at 44.1 Khz), is really all you'd ever need. Most people can't hear above 20 kilohertz (if you're over 18, you're lucky if you even get close to that). In digital audio, you can reproduce any frequency in equal to or less than half of the sample rate. With 44.1Khz, that frequency is 20,050hz. If you want to go really crazy, DVD quality (24 bit at 48Khz). I consider anything about that nice to have from a archival and measurement standpoint, but there's no point in terms of human listening.

I absolutely did! I was really hoping to teach a class about audio at a nearby university, but was told last minute that they can't give it to me for bureaucratic reasons. It's my dream to teach someday so I'm hopeful that I will find another University that will let me teach

doctorzeromd OP ,

I have thought about that, the issue is I'd need to re-run all but 1 of my Ethernet cables to a place where I can put the Celeron box. Once I start messing around with VLANs this is probably what I'll do, but it's going to be a big project.

I'm definitely going to give Adguard Home a shot.

Any thoughts on the best solution for now, basically putting the firewall in between the router and modem? If I plug it into a LAN port on the router and set up DHCP so it is the new gateway, that should work, right? I really wish I could plug it into the WAN port but I don't think DHCP will traverse the WAN to LAN ports on the router.
