bought the 3d printed rack back out to hold my SBCs. Time for some tinkering.
This is Gigabit Land, current home of the Pi 4 and Orange Pi 3 LTS.

While looking for new hardware for our home server (a 19'' mini rack server is very tempting...), I just came across project #minirack
10" rack server builds using a mix of off-the-shelf commercial and #diy #3dprinted mounts, panels, frontplates etc.
Looks interesting (and the mini racks are also rather cute).
Maybe interesting to some of you.

So I bought and used the cursed USB to 1/8" serial cable to reset the password on the APC #UPS network card. It's probably been about 20 years since I had to think about 9600 baud, 8N1 parity.
The ebay seller was pretty cool about it. They sold me 2 of these network cards. One had the default password and one didn't. When I pointed this out, they refunded one. Well, the cost of the cursed cable is about the same as the network card. So it all worked out in the end.
I will give #SchneiderElectric this much credit: one of these UPSes had firmware from 2014. And the release of firmware that I uploaded this week was issued in February 2025. That's pretty impressive, really. Especially for a UPS from APC, which they acquired.
Does anyone else know of a good self hosted ebook library server that can be used with native multi-platform reading app support and sync reading progress?
I really don't want to read books from a web app, I want to be able to read while offline whether on my iPhone, iPad or my Boox e-reader (Android)
I love the way BookFusion works, but I don't want to rely on their cloud storage (or any company's cloud storage for that matter)

@hyperreal #homelab uptime is overrated. There are so many things that can tolerate some downtime. 99.9769% is still 4 jones, right? I mean, there ARE 4 nines in there.
This is my typical monthly uptime.
It really doesn’t matter that things go down for 15 minutes here. An hour there. Email is especially tolerant of downtime. My email really lives there and nowhere else. And it’s fine.
A funny thing is that a lot of my uptime probes are on a 5 minute timer. So outages always look like multiples of 5 minutes. A 6 minute outage will report as 10. So my actual uptime is a little better than this. But not much better.
If I can get my OPNsense device setup again, I can have a DMZ on my home network, migrate my public web services to my homelab, and save money by eliminating my main VPS. I just can't guarantee 99% uptime, then. Which is fine, I guess. And the OPNsense device won't be a dust collector.
New instance, so time for a re #introduction post!
Hi all, I'm Phillip! 
I just moved from infosec.exchange (I still love you Jerry 
) I'm a 20-something guy living with my gf somewhere in the U.S. unfortunately.
Professionally, I am a solo #it admin/automation engineer at a smaller company.
Unprofessionally, I am into #discgolf, #music, #reading, #houseplants, #homelab, #gaming, #SmallWeb, and more. Check out my omg.lol page in my bio if you'd like. Feel free to say hi!
Ugh. Stupid APC UPS with it's proprietary network card and screwball console interface. I bought a secondhand network card for my UPSes, and one of them has a non-default password set.
The password reset procedure is a pain in the ass, and involved a cursed console cable.
One of the cool things about my #homelab is that all my hosts have dual power supplies. So I have 2 big UPSes and 2 separate electrical circuits for them. This means that, like today, when I want to do something to the UPSes, I can power one off, fix it, then power it back on. Then I can do the other and none of my hosts reboot.
Except the one host that had BOTH its power supplies plugged into the same UPS. I would fire the idiot who did that, but I'd be firing myself.
It was such a thrill to talk about #nix at #fosdem ! I'm about a month late posting this, but here is the recording of my talk on "My Nixos-Powered Homelab" #nixos #homelab

With all the issues with O365 recently, i'm thinking of going back to self hosting my emails again.
As a coincidence, HN has a post about Mox, which is a all-in-one Golang mailserver that supports modern standards.
Saves a lot of pain of Postfix/Courier/OpenDKIM and some sort of spam checking...

How to install Debian Testing... and why you might not want to

Converting my dad’s old windows box into a backup server that I can put into my mom‘s basement as an off site backup. Its like 15 years old but only has to run sshd for Restic backup via sftp. Connection via Tailscale. Install is fully automated with NixOS. Secrets managed with sops.
Thinking about writing a blog post about all of this. Let me know if there‘s anything in particular you want me to cover.

Despite running a minor data center in my garage, I still manage to produce a little more electricity from #solar than I use for a few hours. Not bad for February. I have a relatively young Dell server in the #homelab and it only pulls 180W sitting idle. Not bad for 50 cores and 192G of RAM and 10 spinning rust disks.
The giant spikes are where my emergency heat kicked in. It was cold overnight. 15Kw electric resistance heat sucks.
#selfhosted #selfhosting
I realized that I was spending 50¢ every month for 7 Route53 hosted zones at AWS, when I really don't need to do that for some of them. I'm using name.com as my registrar, and they'll do basic #DNS service for free as a part of that.
I didn't want to spend an hour clicking and copy/pasting DNS records, so like any good geek I spent about 6 hours writing a script to do it for me. 
It's a bit of a specialized need. If you're not hosted in #Route53 and not looking to go to name.com, this is not useful to you at all, except as a curiosity of how badly I write python.
But if (a) you're cheap like me, and (b) you've made the same choices as me, this script will save you some time.
Git: Paco Hoperoute53-namecom-dnsA utility to migrate a Route53 DNS zone to name.com's DNS servers.
Continued thread
The punchline on my #DNS reconfiguration is that nothing went wrong because I didn’t actually make any changes that took effect. I do a weird config to have reliable DNS:
I have a hidden master that uses dnsmadeeasy as the public servers. They answer authoritatively but they’re getting records from my #powerdns server.
Well, one problem I have is using CDNs at the apex zone. I use #AWS #cloudfront as my #CDN. This is fine when you use #Route53 as your DNS. They can put alias records in at the apex. But it doesn’t work with dnsmadeeasy secondary zones. The way I run them.
Name dot com is my registrar. They can do alias records. So I think they also do DNS for free. I’m going to migrate my Route53 zones to the free DNS instead of paying $0.50 per zone per month. All this effort will save me about $6.50/month.
#homelab #selfhosting
I'm spending the morning making #DNS changes for 5 different zones. Then I'm spending the afternoon far away from a computer, watching my son perform. I am sure all my DNS configurations will be absolutely perfect. What could possibly go wrong?
With a simple `podman login` and `podman push` you can push container images from your local machine to your #forgejo instance, so you can use said containers on other machines as Forgejo also is an OCI-compliant container registry :) And now you can use these containers to build even more software with forgejo Actions and don't worry about Docker limiting traffic from their registry ;)
