A personal recap of things I explored, learned, or questioned in tech this week.
🌐 Homelab Updates
- Add more services in my Uptime Kuma instance
- Now I have 18 in total
- Created the DNS VLAN to have Pihole instances isolated
- Installed Home Pi-hole
- Installed Work Pi-hole (more restrictive)
- Immich recovered
- I changed a infra of the different disks. That process had broke the Immich instance. It was recovered with not data lost. \o/
- Installed Home Assistant OS
- Created Webhook on Home Assistant and connected to Uptime Kuma to notify my phone every time some service is down
- Installed Duplicati
- I didn’t implement it yet, but I did a small test of backuping up data and restore from Google Drive
Note: it is not ideal having them on a table. Once I have the hardware and services consolidated I will take care of the rack and the right place of everything.
📚 What I Learned
- Differences between HTTP versions (0.9, 1, 1.1, 2 and 3)
- Conceptually understood how QUIC works
- Some extra concepts like: Server Push, Head-of-Line (HOL) Blocking and Keep-Alive (v 1.1)
- K8s is container agnostic
- ContainerD is the most common. However it exists other options like CRI-O.
- It also reported rkt (Rocket), but it is no longer supported since the project was deprecated
- Shebang
- I got the difference between #!/bin/bash and !/usr/bin/env bash
- Dave explained pretty well how the parameters work in a shebang
- AWS
- Understood more in deep EBS and EFS and their differences and applicability
🧠 Things That Surprised Me
- During all this time, I wasn’t able to setup my wireguard because my router is behind CGNAT.
- This made me feel dumb, but anyways this is the way we learn new stuff.
- Promiscuous mode from NICs
- Hypervisors enable the promiscuous mode on NIC to remove the hardware filter
- In Proxmox, we have to uncheck the backup configuration of disks that shouldn’t be part of the backup.
- I was unintentionally backing up a 2TB disk that was breking my schedule backup system. This disk is ignored know.
❓ Open Questions or Doubts
- IOPS and I/O operations are different things
- It is not 100% clear how measure storage speed

💬 Final Thoughts
- This week was wild! I was able to advance a lot in many things
- When I was able to unblock a permission issue in a backup disk, I was able to fix and improve a lot of things on my homelab.
