U-Blue Aurora Upgrade Broke HWA Docker

U-Blue Aurora Upgrade Broke HWA Docker

I use Universal Blue’s Aurora distribution on my daily driver desktop, and I rebooted today which led what I imagine is a kernel update. This broke all of my docker containers using a GPU. Thankfully a reboot and booting into the older environment fixes everything… Linux and immutability FTW Related # Discorse Thread

ZSA typing challenge issue

ZSA I love zsa and have been using a moonlander for a few years now. They recently launched typ.ing as a way to train your typing skills - it’s a lot like monkeytype. I have a thought about it here Today’s Challenge # I went to do today’s daily challenge and have ran into an issue where part of the challenge is to type the forward slash character but it’s actually a keybind on the website for navigation (well done btw!) So when I try to type the challenge I actually bring up the nav menu So for today I’ll take the error on the character to complete it and maybe ZSA can look into this?
Double Check Your DNS Records

Double Check Your DNS Records

My Blog I host my blog on cloudflare and manage my infra with terraform. I got a 522 when I went to recently and I wondered why since worked fine… Terraform # I had this right in the terraform: But turns out the record was commented out for some reason in my terraform code: A quick (careful with this) and we’re up and running with the record now

tl;dr

Copy paste - don’t rely on typing correctly…

The Issue

I use tailscale at home and generally love it. One thing I use it for is whitelisting - so I have some apps publically available and my homelab ones have DNS with SSL certs by LE but I whitelist to only my private IPs so that I can use https at home basically. However I have had a few issues with a couple apps, and I kind of chaulked it up to “network protocol this” “need to figure out that header that” but ultimately I was being lazy and the issues weren’t catastrophic… it was things like:

  1. couldn’t get to my NVR by DNS, so I’d have to use tailscale_ip:port
  2. couldn’t login with my user in jellyfin cause I lock me down to LAN only since I dont’ use a password
  3. gotify wouldn’t connect using DNS

These things aren’t huge but they are annoying and today I decided to figure it out.

Typo! #

I’m not an expert yet but I think the main problem was the CIDR block I was using in my traefik config.

This’ll shock some of you but 10.64.0.0/10 and 100.64.0.0/10 are not the same blocks!

Check your CIDRs

It’s always DNS, and even when it’s not, it’s still probably networking
