I made a typo in my original question: I was afraid of taking the services offline, not online.

Gotcha, that makes more sense.

If you try to run the reverse proxy on the same server and port that an existing service is using (e.g., port 80), then you’ll run into issues. You could also run into conflicts with the ports the services themselves use. Likewise if you use the same outbound port from your router. But IME those issues will mostly stop the new services from starting - you’d have to stop the services or restart your machine for the new service to have a chance to grab the ports while they were unused. Otherwise I can’t think of any issues.

I’m afraid that when I install a reverse proxy, it’ll take my other stuff online and causes me various headaches that I’m not really in the headspace for at the moment.

If you don’t configure your other services in the reverse proxy then you have nothing to worry about. I don’t know of any proxy that auto discovers services and routes to them by default. (Traefik does something like this with Docker services, but they need Docker labels and to be on the same Docker network as Traefik, and you’re the one configuring both of those things.)

Are you running this on your local network? If so, then unless you forward a port to your server on the port your reverse proxy is serving from, it’ll only be accessible from the local network. This means you can either keep it that way (and VPN in to access it) or test it by connecting directly to your server on that port and confirm that it’s working as expected before forwarding the port.

How does power consumption of those x86 PCs compare?

I don’t know that a newer drive cloner will necessarily be faster. Personally, if I’d successfully used the one I already have and wasn’t concerned about it having been damaged (mainly due to heat or moisture) then I would use it instead. If it might be damaged or had given me issues, I’d get a new one.

After replacing all of the drives there is something you’ll need to do to tell it to use their full capacity. From reading an answer to this post, it looks like what you’ll need to do is to select “Change RAID Mode,” then keep RAID 1 selected, keep the same disks, and then on the next screen move the slider to use the drives’ full capacities.

upper capacity

There may be an upper limit, but on Amazon there is a 72 TB version that would have to come with at least 18 TB drives. If 18 TB is fine, 20 TB is also probably fine, but I couldn’t find any reports by people saying they’d loaded 20 TB drives into theirs without issue.

procedure

You could also clone them yourself, but you’d want to put the NAS into read only mode or take it offline first.

I think cloning drives is generally faster than rebuilding them in RAID, as well as easier on the drives, but my personal experience with RAID is very limited.

Basically, what I’d do is:

0. Take the NAS offline or make it read-only.
1. Pull drive 0 from the array
2. Clone it
3. Replace drive 0 with your clone
4. Pull drive 2 (from the other mirrored pair) from the array
5. Clone it
6. Replace drive 2 with your clone
7. Clone drive 0 again, then replace drive 1 with your clone
8. Clone drive 2 again, then replace drive 3 with your clone
9. Put the NAS back online or make it read-write again.

In terms of timing… I have a Sabrent offline cloning hub (about $50 on Amazon), and it copies data at 60 Mbps, meaning it’d take about 9 hours per clone. Startech makes a similar device ($96 on Amazon, that allegedly clones data at 466 Mbps (28 GB per minute), meaning each clone would take 2.5 hours… but people report it being just as slow as the Sabrent.

Also, if you bought two offline cloning devices, you could do steps 1-3 and 4-6 simultaneously, and do the same again with steps 7-8.

I’m not sure how long it would take RAID to rebuild a pulled drive, but my understanding is that it’s going to be fastest with RAID 1. And if you don’t want to make the NAS read-only while you clone the drives, it’s probably your only option, anyway.

They’re focused entirely on the shitty practices those other manufacturers engaged in. In that regard, Valve didn’t do much (and that’s a good thing).

Good to know! I saw that mentioned on some (apparently outdated) Comodo marketing copy as a benefit over LE

EV certs give you an extra green bar or something along those lines. If your customers care about it, then you have to. If they don’t - and they probably don’t - it’s a waste.

What exactly are you trusting a cert provider with and what are the security implications?

End users trust the cert provider. The cert provider has a process that they use to determine if they can trust you.

What attack vectors do you open yourself up to when trusting a certificate authority with your websites’ certificates?

You’re not really trusting them with your certificates. You don’t give them your private key or anything like that, and the certs are visible to anyone navigating to your website.

Your new vulnerabilities are basically limited to what you do for them - any changes you make to your domain’s DNS config, or anything you host, etc. - and depend on that introducing a vulnerability of its own. You also open a new phishing attack vector, where someone might contact you, posing as the certificate authority, and ask you to make a change that would introduce a vulnerability.

In what way could it benefit security and/or privacy to utilize a paid service?

For most use cases, as far as I know, it doesn’t.

LetsEncrypt doesn’t offer EV or OV certificates, which you may need for your use case. However, these are mostly relevant at the enterprise level. Maybe you have a storefront and want an EV cert?

LetsEncrypt also only offers community support, and if you set something up wrong you could be less secure.

Other CAs may offer services that enhance privacy and security, as well, like scanning your site to confirm your config is sound… but the core offering isn’t really going to be different (aside from LE having intentionally short renewal periods), and theoretically you could get those same services from a different vendor.

You can get wildcard certs with LetsEncrypt (since 2018): https://community.letsencrypt.org/t/acme-v2-production-environment-wildcards/55578

I use --format-sort +res:1080, which, if my understanding of the documentation is correct, will make it prefer 1080p, the smallest video larger than 1080p if 1080p isn’t available, or the largest video if nothing 1080p or larger is available.

res is the smallest dimension of the video (so for a 1080x1920 portrait video, it would be 1080).

Default sort is descending order. The + makes it sort in ascending order instead.

Does your script handle bi-directional sync or one-way only?

Thanks for that! I recommend anyone who wants to minimize risk to follow their instructions for self-hosting:

Is the source code available and can I run my own copy locally?

Yes! The source code is available on Github. Its a simple static HTML application and you can clone and run it by opening the index.html file in your browser. When run locally it should work when your computer is completely offline. The latest commits in the git repository are signed with my public code signing key.

Generally people don’t memorize private keys, but this is applicable when generating pass phrases to protect private keys that are stored locally.

Doesn’t their API also require you to allow-list IPs, making it basically useless for dynamic DNS?

From https://www.namecheap.com/support/api/intro/ under “Whitelisting IP.”

Reverse proxies aren’t DNS servers.

The DNS server will be configured to know that your domain, e.g., example.com or *.example.com, is a particular IP, and when someone navigates to that URL it tells them the IP, which they then send a request to.

The reverse proxy runs on that IP; it intercepts and analyzes the request. This can be as simple as transparently forwarding jellyfin.example.com to the specific IP (could even be an internal IP address on the same machine - I use Traefik to expose Docker network IPs that aren’t exposed at the host level) and port, but they can also inspect and rewrite headers and other request properties and they can have different logic depending on the various values.

Your router is likely handling the .local “domain” resolution and that’s what you’ll need to be concerned with when configuring AdGuard.

If you use that docker compose file, I recommend you comment out the build section and uncomment the image section in the lemmy service.

I also recommend you use a reverse proxy and Docker networks rather than exposing the postgres instance on port 5433, but if you aren’t familiar with Docker networks you can leave it as is for now. If you’re running locally and don’t open that port in your router’s firewall, it’s a non-issue unless there’s an attacker on your LAN, but given that you’re not gaining anything from exposing it (unless you need to connect to the DB directly regularly - as a one off you could temporarily add the port mapping), it doesn’t make sense to increase your attack surface for no benefit.

I’m not the person you responded to, but I can say that it’s a perfectly fine take. My personal experience and the commonly voiced opinions about both browsers supports this take.

Unless you’re using 5 tabs max at a time, my personal experience is that Firefox is more than an order of magnitude more memory efficient than Chrome when dealing with long-lived sessions with the same number of tabs (dozens up to thousands).

I keep hundreds of tabs open in Firefox on my personal machine (with 16 GB of RAM) and it’s almost never consuming the most memory on my system.

Policy prohibits me running Firefox on my work computer, so I have to use Chrome. Even with much more memory (both on 32 GB and 64 GB machines) and far fewer tabs (20-30 at most vs 200-300), Chrome often ends up taking up far too much memory + having a substantial performance drop, and I have to to through and prune the tabs I don’t need right now, bookmark things that can be done later, etc…

Also, see https://www.techspot.com/news/102871-zero-regrets-firefox-power-user-kept-7500-tabs.html - I’ve never seen anything similar for Chrome and wasn’t able to find anything.

Definitely not, I do the same.

I installed 64 GB of RAM in my Windows laptop 4 years ago and had been using 64 GB of RAM in the laptop that it replaced - which was from 2013 (I think I bought it in 2014-2105). I was using 32 GB of RAM prior (on Linux and Windows laptops), all the way back to 2007 or so.

My work MacBook Pros generally have 32-64 GB of RAM, but my personal MacBook Air (the 15” M2) has 16 GB, simply because the upgrade wasn’t a cost effective one (and the M1 before it had performed great with 16) and because I’d only planned on using it for casual development. But since I’ve been using it as my main personal development machine and for self-hosted AI, and have run into its limits, when I replace it I’ll likely opt for 64 GB or more.

My Windows gaming desktop only has 32 GB of RAM, though - that’s because getting the timings higher with more RAM - particularly 4 sticks - was prohibitively expensive when I built it, and then when the cost wasn’t a concern and I tried to upgrade, I learned that my third and fourth RAM slots weren’t functional. I could upgrade to 64 GB in two slots but it wouldn’t really be worth it, since I only use it for gaming.

My Linux desktop / server has 128 GB of ECC RAM, though, because that’s as much as the motherboard supported.

I haven’t personally used any of these, but looking them over, Tipi looks the most encouraging to me, followed by Yunohost, based largely on the variety of apps available but also because it looks like Tipi lets you customize the configuration much more. Freedom Box doesn’t seem to list the apps in their catalog at all and their site seems basically useless, so I ruled it out on that basis alone.
