So, if I can't trust an IoT device, a camera, a printer, any smart device that calls home, and now some brands of TV and set-top boxes, what is left to trust in my network? Should I just have one VLAN per device type and not let anyone talk to anyone? This is getting out of hand, and is very tiring. Ps.: I'm not asking for technical advice, this is just me venting. #HomeLab #HomeAssistant #Networking #InfoSec @homelab@fedigroups.social

Is anyone in the home lab community running NixOS on a Raspberry Pi 4B (8GB), and could share your frustrations or cautionary tales? I am seriously considering dividing into that. I don't need convincing. At this point I just need to know where the rakes and the skeletons are. So basically just give me the dirt. 😄 #HomeLab #NixOS @homelab@fedigroups.social

I'm glad the Matter protocol exists, but the fact that there are Matter-over-WiFi and Matter-over-Thread just makes it more complicated than it needs to be... 🙄

After procrastinating a decision about which Kanban tool to use, I finally weighed all the available choices and landed on @vikunja@social.linux.pizza I think this was the first time that a software having their presence on Mastodon made part of my reasons to choose something. Another one is the integration with Home Assistant. So far, so good. Haven't used it for more than a few minutes to create some fake tasks, but it's been nice. Now I need to figure out how to migrate from my old Kanboard. #HomeLab #SelfHosted #Jira #Kanban #Vikunja @homelab@fedigroups.social

Does anyone have a recommendation for a Raspberry Pi 4 (specifically 4) HAT that can provide PoE *and* a full size NVME at the same time? I have the official PoE HAT, but it doesn't provide enough power for an NVME connected via USB enclosure, and I would prefer to keep the PoE if possible (since I can use it as "poor-man's remote reboot"). And, in case you're wondering: I do have a PoE splitter dongle sitting idle in a cabinet, but I would prefer to avoid it because of the Pi's USB-C position. But I would move it around if there isn't a better way. EDIT: scratch that. I did some research and apparently it doesn't matter how big the PoE HAT or splitter are, there will never be enough power on the USB port due to a Pi 4 limitation. I guess my only solution is to keep the NVME on it's own brick. 🤷 #HomeLab #RaspberryPi @homelab@fedigroups.social

A fresh Home Assistant install feels so nice. I'm this close to not restore the backup and simply start over. Context: I'm migrating from Docker to full HAOS. #HomeAssistant @homeassistant@fedigroups.social

I just had to remove the middle node to add a disk, and the rack space + my cabling scheme made everything smooth, and didn't cause any disruptions. That was the last test to confirm that Lab Rax is awesome. (see the post above in the thread for details about the rack) #HomeLab #3DPrinting #10inchRack @homelab @3dprinting

@jerry@infosec.exchange Maybe over engineering: put the power adapter behind a smart plug, and make Home Assistant understand when your laptop is off (or you're not using OBS), then make it turn off the camera.

I don't use Claude Code, but when talking about AI/LLM the name most likely needs to be mentioned, one way or another (I do use Claude models though).

The problem is that I've been having some conversations in real life over the past few weeks, and it bothers me how I want to talk about CLOUD computing, and people keep thinking I'm talking about Claude.

I think I'm gonna start saying KLAH-L-D or KLOWD to see if it sounds different. 🫤

@hyc@mastodon.social Just to make it clear: I'm not opposed to non-developers creating apps. Being an infra person, I've had my fair share of apps I created myself. I just wish people would check existing apps, or engage with them, before going on their own. At least the old ways of forking projects were being honest about it.

@zrail@hachyderm.io @jessicaddooley@infosec.exchange @paul_ipv6@infosec.exchange @homelab@fedigroups.social These are indeed very interesting projects. The closest similar thing I've ever seen is per-user or per-group VPN profiles, that only allow certain hosts/routes, which can probably be implemented with Tailscale ACLs. But that's a lot of work, and might not be easy to implement on home networks (restricting inter-device comms in the same wired LAN).

That's a wrap for DevOpsDays Raleigh. Another great conference, with a very interesting note: it had the right amount of non-AI vs AI talks, and most importantly, whenever AI was mentioned was relevant, and not a vendor talk. The open spaces fostered some great conversations, and the hallway track is always amazing. Can't wait for next year!

@spezivernichter @homelab @3dprinting I printed the trays with PETG in the hopes that it would be sufficient to hold the weight, so they're just floating. If they start bending I have a backup plan to print some holders to put in the back, since the back also has screw holes. I did initially consider a full-size tray, but decided to take a chance with enough-sized ones. We'll see how it settles over time.

@rachel @osman When part of my work was to manage a bit of data center assembly, we did run some experiments with back mounted switches. It works well, but it's highly dependent on the rack type and the size of the patch cords. But, like I said in the blog, I am still thinking about what to do in my case. I don't think I will mount the switch in the back, but I most likely will find some kind of cable management. Maybe I will not over-complicate and just put another keystone and run the cables trough the holes. I don't know yet.

I have been avoiding the problem you two described for a very long time: I have the Raspberry Pi OS on the SD card, but all the application data is running out of an NFS share. I do intend to move to a full boot from a USB device (either HDD or NVMe, depending on what I can find in a closet).

Possibly controversial take: I like when the InfoSec team is very active/present and breathes down my neck. Gives me the confidence that I'm either doing something right, or they can stop me from doing something wrong. Of course it doesn't remove my responsibility of doing the appropriate research. #InfoSec #SRE #DevOps
