Angry Admin!

Being frustrated by incomplete or wrong tech blogs, I decided to write a blog myself. If you just copy-paste the example code snippets here you might delete the internet or start a fire.

Hosting your own iOS Backups and automate it with Homeassistant

Motivation I recently got my first iPhone after years of Android. And the first error message I received after moving my data from my old phone to the new phone was: Your iPhone can not be backed up. Huh? Why? Ah! Not enough iCloud Storage! But I’m doing all my backups myself and store them locally. With Android and e.g. LineageOS and SeedVault a setup I was used to. Now it was the challenge to find a solution for iOS....

The assembly was straight-forward but the printing… I was used to Marlin and the Chitu Firmware is just a pain with their proprietary limitations and weird custom GCodes....

NVIDIA Diagnostics with MATS and MODS

What is MATS and MODS MATS stands for memory automated test system and MODS stands for modular diagnostics software and are two pieces of software “leaked” from NVIDIA.

Access resources cross account in terraform

Why do I need multiple Accounts? There certain hard-limits in AWS services you can’t raise, even with a support ticket. So make sure you don’t hit them. Otherwise scaling out will be a pain. WTF? How should I manage this in terraform? RTMF? Also, this is basically build on my folder structure, which you can find here.

Sometimes even in multiple regions. So you better think about how you organize all these files in terraform.
