Fix slow ZSH startup due to NVM

Many zsh users use oh-my-zsh in combination with the nvm plugin to use the right node version for every project, configured through .nvmrc files. This, in turn, slows the startup of your shell quite a lot. But we can easily fix this slow zsh startup! Instead of always loading your nvm autocompletion, we can command oh-my-zsh to just load nvm ressources on-demand, also known as lazy-loading.

Securing TrueNAS with a cheap backup to the cloud

Backups with Time Machine, Nextcloud, iSCSI storage - all is stored on my TrueNAS VM. It's running in proxmox with raid controller passthrough. As my proxmox machine just crashed due to faulty ram / ECC errors two days ago, I thought that I might be better off with an offsite backup for all these important storage pools. Thats where I discovered TrueNAS' capability of running Cloud Sync Tasks, which periodically run a TrueNAS backup to cloud providers you choose.
