Self-hosting

I had to replace my UPSs a few weeks ago on short notice due to hardware failure, and I ended up getting a few LiFePO4 ones as a stopgap since they were on sale and I'd always wanted to try them. So far, so good. Curious if anyone else has switch to lithium UPSs from lead-acid and how that's going for you.

I have a big 20Ah, 48v e-bike battery that I've used with a sine-wave inverter for standby power, and it's a bit over 11 years old and going strong. So, as far as the batteries in these are concerned, I am cautiously optimistic that they'll last close to the 10 years they're advertised as. The electronics and inverter...we'll see, I guess.

Bonus question: While we're on the subject, has anybody tried those drop-in replacement 12V LiFePO4 batteries for regular UPS's? Supposedly, it says the BMS in them can work with the lead-acid chargers in UPSs and safely charge them, but I'm not sure I trust that.

I live in a rural aussie (with no fibre options) area with the worlds shittiest internet and especially bad upload. I been self hosting a bunch of things and simply just struggling through the shit connection.

Will be getting starlink to remedy the internet issue but it seems i need a business (priority) plan to get a public ip so i can access my services from the greater internet. This is however more expensive and i would like to avoid the additional cost if possible.

I was thinking i could wireguard proxy from my server at home to a cheap/free vps to bypass the restrictions but i suspect that would mess with how nginx on my home server manages ports etc. Plus i use my own hardware not just for security but also no recurring costs otehr than power so paying for a vps just to proxy seems like a waste.

Also been having dns issues with duckdns vos dynamic ip starlink seems not to support static ips so how should i resolve this issue.

Any advice or reccommendations?

First let me make sure it's clear that I am NOT trying to extend runtime by connecting two UPSs in series. That's been asked a million times on various forums, and is not what I'm trying to accomplish.

I've had 3 UPS units fail on me in the last 12-18 months, and I'm starting to wonder if it's the power flickers that are doing them in. My power rarely goes out for more than a minute or five, but before it does, it always violently flickers for a few seconds. Those flickers are hell on my unprotected equipment, and I'm wondering if that's what has caused my UPSs to die prematurely (the newest one barely lasted 5 months).

The old ones still function and still seem to do automatic voltage regulation, but none of them last more than 1-2 seconds once they switch to battery. I've tested the batteries, and they're fine; they were also all replaced about 9 months ago.

So, what I'm hoping is that the old ones can sit upstream of the new UPSs to take the brunt of any rapid brownout /surges and keep my new UPSs healthy. They're all pure sine wave and similarly rated.

Thoughts? Warnings/cautions?

Happy birthday to Let's Encrypt !

Huge thanks to everyone involved in making HTTPS available to everyone for free !

Consider watching this video with FreeTube, a nifty open-source program that lets you watch YouTube videos without Google spying on your viewing habits!

Combined with Libredirect, which automatically opens youtube links in Freetube, it becomes really slick and effortless to use.

Long-awaited release, with the flagship feature of custom attributes! This unlock many integrations, notably Linux user management through PAM.

The founder of Drupal posted recently about this self-hosted and completely solar-powered personal site he made, in Boston of all places.

He describes the hardware, software, and the challenges he ran into while setting it all up. The site even includes automatically updating statistics about the system and battery. There's no backup or fail over, so if the battery drains due to cloudy or cold weather, the website will simply go offline for a while and he's fine with that.

Enjoy.

Hey guys!

I want to convert my now corebooted Thinkpad T430 into a Nextcloud server and possibly more (Syncthing, maybe Tor, maybe more)

1 500GB SSD, 1 1TB SSD

Currently runs Fedora Kinoite, I could rebase to something like secureblue uCore, Fedora IoT, uBlue uCore, ...

Not sure if those would have broken configs though.

Maybe I would prefer something with slower pace, but tbh the pace of CentOS bootc becoming a thing is quite frustrating. This would likely be the perfect 'install and forget' distro for many, a KDE Image would be there in no time.

I wouldnt want to use a traditional distro, even though a base Debian or AlmaLinux/ Rockylinux (what the hell was that of a hydra? Cut off one head, spawn 2? what are the differences??) could just be fine. I used Debian in the past, it really just works.

I would like

• Nextcloud AIO docker image, maybe with podman? It is supposedly more secure but the world runs on Docker, and all is fine. Podman is a pain quite often.
• some nice management like Cockpit
• dyn DNS, for example with NoIP, best free
• secure ssh, that should be no issue
• btrfs? or zfs? with backups to a secondary drive
• automatic updates with snapshot creation. Atomic system would be easiest here.
• easy to use and secure reverse proxy, with DynDNS for reliable address on the internet. NGINX, Traefik, Caddy, what is the best here??

Here I am not sure if I should use 1TB + 1TB, or 500GB used and 1TB backup. BTRFS backups can be incremental.

while I made a list of BTRFS tools I still have no idea what the best tool for this job is.

This is a guide I wrote for Immich's documentation. It features some Immich specific parts, but should be quite easy to adapt to other use cases.

It is also possible (and not technically hard) to self-host a protomaps release, but this would require 100GB+ of disk space (which I can't spare right now). The main advantages of this guide over hosting a full tile server are :

• it's a single nginx config file to deploy
• it saves you some storage space since you're only hosting tiles you've previously viewed. You can also tweak the maximum cache size to your needs
• it is easy to configure a trade-off between map freshness and privacy by tweaking the cache expiration delay

If you try to follow it, please send me some feedback on the content and the wording, so I can improve it

Hi everyone,

I would like to enable Cross-Origin Resource Sharing on my Nginx server. for few origins (cors requestor)/domains.

I've found this article https://www.juannicolas.eu/how-to-set-up-nginx-cors-multiple-origins that is nice, but not complete and on my browser seem really hard to read due to the layout 🤮

So I've opened a CodeBerg git repository for the good soul that want to perfect this piece of code the allow the most of use to use CORS with Nginx.

https://codeberg.org/R1ckSanchez_C137/BestOfxxx/src/branch/main/Nginx/CORS_MultiDomains.py

If you don't want to create an account on codeberg feel free to post your code here !

server {
    # Server

    map "$http_origin" $cors { # map in Nginx is somewhat like a switch case in a programming language.
        default ''; #Seem to set $cors to '' empty string if none of the follwing rexeg match ?
        "~^https:\/\/([\w-_\.]+\.)?example.com$" "$http_origin";
            #regex domain match
            # ~ mean I suppose the string is RegEx ?
            # Need to come with a RegEx expression that match https://anything.example.com/[optional ports and Query string ?X=Y]
        "~^https:\/\/([\w-_\.]+\.)?example2.com$" "$http_origin"; #regex domain match
        }
               

    location /static {
        
        # if preflight request, we will cache it
        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Max-Age' 1728000; #20 days
            add_header 'Content-Type' 'text/plain charset=UTF-8';
            add_header 'Content-Length' 0;
            return 204; #https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/204 }

        if ($cors != "") {
            add_header 'Access-Control-Allow-Origin' "$cors" always; # <-- Variable $cors
            add_header 'Access-Control-Allow-Credentials' 'true' always;
            add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT, DELETE, OPTIONS' always;
            add_header 'Access-Control-Allow-Headers' 'Accept, Authorization, Cache-Control, Content-Type, DNT, If-Modified-Since, Keep-Alive, Origin, User-Agent, X-Requested-With' always;}

       # configuration lines...

    }
}

}

does anyone here have experience hosting a Signal proxy and/or a Tor relay? there's a blog post on signal.org asking for folks to help, and i can but i don't know enough about network security to feel safe/confident doing some of this stuff. same with Tor - i've always wanted to host an exit relay (and in fact have this whole long theory about how every public library in the US should host an exit relay, but that's for another post someday maybe).

do any of you have experience with doing this? what kind of best practices would you recommend? any good resources on protecting your network that you might point me to? i will be getting my Net+ cert within the next year but for now i am starting from "enthusiastic beginner" and want to be helpful, but careful.

This may be deemed slightly off topic but I felt like this community might know the answer to this. I'm looking for a way to permanently embed information about who is in a photo, but when I search Google I just get some forum posts from 10 years ago. Surely there is something more recent? How would you go about doing this? Let's assume they are JPG.

I thought about this when looking through photos from my grandparents, where the names are written on the back of the photo. I have many digital photos from ten years ago and I've already forgotten the names of some of the people so imagine what it will be like in another 30 years.
