For those kind of issues I’d recommend snapshots instead of backups

Syncthing or unison might be what you want

Your system will appeal to the intersection between people who like gambling and people who like donating to charities.

Even among them, I don’t see why anyone would prefer putting 100$ in your web3 thingie instead of just donating 50$, gambling with 45$, and buying a beer with the 5$ they would lose to you… well, there are a lot of stupid peculiar people (especially among crypto bros), so you might actually be ok.

About the implementation, the 50% to charities should be transferred automatically… what’s the point of a smart contract if people must trust you to “check the total donations and create a donation on The Giving Block”?

PS:

IDK about the US, but where I live gambling is regulated very strictly: make sure to double check with a lawyer before getting into trouble.

2 more cents :)

I’ve been using syncthing for a while now, on different devices, and the only unreliability I’ve run into is with android killing syncthing to save battery life, which is kinda hilarious, considering all the vendor- and google-provided crap they happily waste battery on (I don’t use it, but for what I’ve heard iOS is even worse in this regard).

Specifically, I have a samsung tablet where, no matter how much I tinkered with system settings, synchthing would only run if I manually launched the app or while the tablet was charging (BTW I still use that same tablet, but it now runs LineageOS and syncthing works flawlessly).

All this is to say, you should probably look into system settings and research ways to convince your OS to do what it’s supposed to rather than tinkering with syncthing itself.

I don’t see the ethics implications of sharing that? What would happen if you did disclose your discoveries/techniques?

I don’t know much about LLMs, but doesn’t removing these safeguards just make the model as a whole less useful?

Read this, delete this post and try again.

Best of luck to you!

I’m trying to understand Git, but it’s a giant conceptual leap.

Git is not that different from svn (I mean, the biggest hurdle is going from a shared folder to any version control system)… I’d say the main difference is that branches live in a different namespace than files (ie. you don’t have trunk/src/whatever but just src/whatever in the main branch). On top of that there’s that commit and push are two different things (and the same with fetch and checkout) and that merges are way easier than in svn (where you had to merge stuff manually).

If you create a repo locally and clone it twice in two different directories, you can easily simulate what would happen when you and a coworker collaborate via a centralized repo (say, github) - do a few experiments and you’ll see it’s not as complicated as it seems (I’d recommend using the CLI instead of some GUI client: it’s way easier to figure things out without the overhead of learning to differentiate between git concepts and how the GUI tries to help).

Personally, I would sell everything and get a used PC on ebay (a small “minipc” one, unless space for hard disks is needed).

Take a look at what you could buy on ebay just by selling off the nvidia card.

why is your network like this?

Well, at the moment my network is actually flat :)

This is an experiment I’m doing because I wanted to have all the management stuff on a different subnet (eg. adguard dns is on the “regular” subnet everyone uses, but its web interface is on the special subnet only select devices can talk to).

Of course (like with most stuff in my homelab), it’s not like I really have a super-compelling security reason to that, it’s mostly that I wondered “what if?” :D

Oh. the ping option you are referring to is -I (upper case) and takes either an interface name or an ip. I did try giving a .10/24 IP to the PC and the results were consistent with scenario 1 (pings where source and destination are on the same subnet work, pings acrrss subnets don’t), so I didn’t mention that in the OP

I don’t think I quite explained the situation well enough: my server only has 1 ethernet port (same as my PC), otherwise I wouldn’t have bothered with vlans (well, I would still have bothered, since my house still only has one “backbone” cable running through it, but I would have configured it on the switches only).

Anyway… a few of the things you say/imply go against my understanding of networking, so one of us would better go back RTFM as you suggest :) (just kidding - most probably I just don’t understand what you mean)

Thanks! Forwarding is disabled. I don’t want the server to steal the router’s job :)

So the request goes trough but the replies are discarded ? That could actually be it!

I think there was an option to allow that… I’ll search it and give it a try. Thanks!

I tried dropping the default routes (one at a time) and it doesn’t make a difference, which isn’t (I think) surprising as all traffic is local as far as the server in scenario 1 is concerned. Also IIUC only the default gateway with the lowest metric actually counts.

If going the route of a backup solution, is it feasible to install OpenWRT on all of my devices, with the expectation that I can do some sort of automated backups of all settings and configurations, and restore in case of a router dying?

My two cents: use a “full” computer as your router (with either something like OPNsense or any “regular” linux distro if you don’t need the GUI) and OpenWRT on your access points.

Unless you use the GUI and backup/restore the configuration (as you would with proprietary firmwares), OpenWRT is frankly a pain to configure and deploy. At the moment I’m building custom images for all my devices, but (next time™) I’m gonna ditch all that, get an x86 router and just manually manage OpenWRT on my wifi APs (I only have two and they both have the same relatively straightforward config).

It’s a pain that I know can be solved with buying dedicated access points (…right?)

Routers and access points are just computers with network interfaces (there may be level-2-only APs, but honestly I’ve never heard of any)… most probably your issue is that the firmware of your “routers as access points” doesn’t want to be configured as a dumb AP.

Does it still? Looks like the bubble is about to explode

How much data are we talking about?

A free mega.nz account should be fine for everything except family fotos and legally obtained music/movies.

I’d say a good middle ground could be making that stuff only visible from your mom’s user (or even setting up a completely separate server)?

It depends on what YOU want to do, really… personally, I would be ok hosting religious nonsense if asked, as long as it’s not generally available in kids’ accounts and stuff (also, porn), but I would come clean and outright refuse if it was neonazi,racist and/or conspiracy stuff. It depends on where you decide to draw the line.

BTW: there’s also the passive/aggressive, cowardly option of sayng “I’ll rip them when I have time” and then sequester all the DVDs and only ever find the time to rip the ones you don’t mind

man this is getting real popular (kinda like “why not both?” a while ago)

IMHO Ansible isn’t much different than a bash script… it has the advantage of being “declarative” (in quotes because it’s not actually declarative at all: it just has higher-level abstractions that aggregate common sysadmin CLI operations/patterns in “declarative-sounding” tasks), but it also has the disadvantage of becoming extremely convoluted the moment you need any custom logic whatsoever (yes, you can write a python extension, but you can do the same starting with a bash script too).

Also, you basically can’t use ansible unless your target system has python (technically you can, but in practice all the useful stuff needs python), meaning that if you use a distro that doesn’t come with python per default (eg. alpine) you’ll have to manually install it or write some sort of pythonless prelude to your ansible script that does that for you, and that if your target can’t run python (eg. openwrt on your very much resource-constrained wifi APs) ansible is out of the question (technically you can use it, but it’s much more complex than not using it).

My two cents about configuration management for the homelab:

• whatever you use, make sure it’s something you re-read often: it will become complex and you will forget everything about it
• keep in mind that you’ll have to re-test/update your scripts at least everytime your distro version changes (eg. if you upgrade from ubuntu 22.04 to 24.04) and ideally every time one of your configured services changes (because the format of their config files may in theory change too)
• if you can cope with a rolling-style distro, take a look at nix instead of “traditional” configuration management: nixos configuration is declarative and (in theory) guarantees that you won’t ever need to recheck or update your config when updating (in reality, you’ll occasionally have to edit your config, but the OS will tell you so it’s not like you can unknowingly break stuff).

BTW, nixos is also not beginner-friendly in the least and all in all badly documented (documentation is extensive but unfriendly and somewhat disorganized)… good luck with that :)

With the very limited number of drives one may use at home, just get the cheapest ones (*), use RAID and assume some drive may fail.

(*) whose performances meet your needs and from reputable enough sources

You can look at the backblaze stats if you like stats, but if you have ten drives 3% failure rate is exactly the same as 1% or .5% (they all just mean “use RAID and assume some drive may fail”).

Also, IDK how good a reliabiliy predictor the manufacturer would be (as in every sector, reliabiliy varies from model to model), plus you would basically go by price even if you need a quantity of drives so great that stats make sense on them (wouldn’t backblaze use 100% one manufacturer otherwise?)
