Arch Linux is my favourite distribution for long time. I can get the benefit of bleeding-edge and highly configurable system, yet still manageable with its lovely package management like pacman, AUR and additionally brew. I also use ansible / chef to manage the workstations / VMs for the sake of immutability. But, managing the playbooks takes time even for doing simple things. In distrowatch, there are page hit ranks and I already familiar with most of them in the list and I found NixOS there, which I haven’t used. I interested with the declarative configuration approach that NixOS offer to manage the system. Go straight to the documentation rightaway, and try it in VM. Aaaand.. I got overwhelmed at first with the nix language. 30 minutes learning the configurations, finally I can make the configuration usable and enjoying it more than Arch!

Recently, I just got to know about Docker Build Cloud which allows us to build our image with cloud builder. I got to know when I try to built some images and it takes long time to complete and decided to read the docs and found out there is Docker Build Cloud section.

With this, your build will be offloaded to the cloud instance as well as the cache, so no need to worry when your Internet is problematic or your machine is not strong enough to build the image. ...

Since now I currently in Indonesia, I was decided to wake them up again! The Born of the Undead I put my homelab in my working room, and since my house was empty and no one take care of it, then yaaa! Its fully covered by dusts. Unfortunately, several devices completely dead. I tried to turn on everything, zonk! I need to start from scratch again. Since I don’t want to spend too much time building it at once, I started to pick up one of the machine that I often used for hypervisor. My DeskMini X300 is still solid AsRock! I was using plain LibVirt in the past and manage everyting using terraform-libvirt which allows me to manage everything through pipeline. But, this time I try to do differently. ...
