Hi All,

Recent 1st time homeowner, which I viewed as a trade of having to mow my lawn for being able to drill holes where ever I wanted.

To wit: I have a basement that is just barley to short for me to stand up in, and is generally pretty dry. Bummer as a basement, awesome for running wire. Humidity can be higher, but I've been monitoring it and it seems like I can have pretty good control with a dehumidifier. I have growing frankenstien of a home assistant setup that I use to monitor and control the humidity; I do not let the dehumidifer do that on its own.

**The question: ** What humidity would I need to target to move my server to the basement? I see some pretty huge windows when I look around.

I also have some dust concerns, but I plan on addressing that by making a very large cabinet/ small room with some fabric sheeting; enough to allow temp exchange but restrictive enough to keep dust out/ reduce volume a filter needs to clean (I also have some AQ sensors linked to home assistant I can deploy).

thanks for any help!

What actually counts as a copy under the 3-2-1 rule, why a RAID mirror or a snapshot only protects against one kind of failure, and the one-page inventory that exposes the gaps.

Do you guys have a nice app for tracking stuff at home, like stuff in storage bins, food pantries, etc..?

I had a Blackview MP-80 Mini-PC that I removed from its enclosure, it was kind of just chilling on my rack and I wanted a way to mount it properly.

I bought my 3D printer basically just to design and print things for my rack, I first made the light blue part to test it out and see if everything alignes, once I confirmed that I took a 10" rack and modified it by chopping a bit off and adding the MP-80 Mount.

I'm quite happy how it's turned out, thought I'd share.

My bulk storage box is a used Dell R730xd, and after going through the process I've got a short list of things I wish I'd known going in:

• Check iDRAC Enterprise licensing before buying, not after. A lot of used listings have it stripped or expired, and losing real remote management is a bigger downgrade than it sounds like on paper.
• Drive caddies are where sellers actually make their margin. Sometimes a handful of caddies costs more than the drives you're putting in them. Either buy fully populated or budget for caddies as their own line item.
• Idle power draw and fan noise are datacenter numbers, not homelab numbers. This thing alone can pull more than my whole mini PC cluster combined, and it is loud. Figure out where it physically lives before you figure out what runs on it.
• Being out of warranty is a fine tradeoff for a storage/backup role (worst case is a resilver), a worse one for anything that actually needs uptime.

Worth it in the end, ZFS on this thing runs circles around anything in the mini-PC tier, just went in more clear-eyed the second time than the first.

I put together a longer checklist version of this over at rHomeLab.com if anyone's curious (linking since it's directly on-topic, not trying to spam), but the short version above covers the big ones.

After coming close to running out of resources last week and having to re-purpose another device turning it into a 3rd Proxmox node, it got me thinking about how easily ZFS ARC cache and VM overhead sneak up on you.

So, I built a basic tool for rough guidance.

It calculates vCPU overcommit ratios and RAM allocation locally in your browser. Just pure client-side math so you don't accidentally OOM your hypervisor like I almost did. Inputs stay right in your browser and aren't saved anywhere.

Feedback or sanity checks on the math are welcome.

Omada platform was found to be vulnerable in several ways

I am trying to get rid of Cloudflare. The last piece of the challenge is an alternative to Cloudflare tunnel. I've found and installed Pangolin, but I am getting stuck in the "Site configuration" part. Maybe it's an issue with the Pangolin's recommendation (based on a secondary traefik) which is getting in the way of my "main" traefik deployment.

I might put some more effort to get this going, but if anyone is already using or has used it before and can share some experiences, I'd be curious to hear them.

Hi, I am looking for libre solutions to buy for my home surveillance system.

I know that there are open source NVRs, but are there open source WiFi cameras? Cabled cameras just transmit an electrical signal so I don’t care about them.

Someone gifted me a Tapo C-210 but I don’t like the fact that it transmits videos to TpLink’s servers. I just want my self-hosted solution.

Thank you.

Which approach do you think is better, and why?

1. FIDO2
2. HMAC-SHA1
3. OpenPGP (alternative guide)

Or do you think there is an even better way to use a hardware security token to unlock drives having LUKS full disk encryption?
