There are architectures you see and architectures you don't. ARM is the most extreme case of the second category: it runs in the phone in our pocket, in the home router, in the eighty-euro board that serves as a home server for millions of tinkerers, in the datacentres of Amazon and Google. It is everywhere, and almost nobody knows what it is. It took me years too to bring it into focus, and the occasion was a Raspberry Pi 3 that I had decided to turn into a Nextcloud — the first brick of what would become, in the years to come, my small homelab — many years ago. It was a line in /boot/config that made me notice the thing: the Pi's processor, a Broadcom BCM2837, used the same architecture as the Android phones I had hacked for years. ARM. Same instruction set, same underlying logic, same family.

It was an ordinary Friday evening. The parcel had arrived with the courier that morning, but I only opened it after dinner, with that silent ceremony I perform every time new hardware shows up – as if opening a box too quickly were a form of disrespect toward the object. Inside was a HUNSN 4K. Small, almost ridiculously small. A mini PC in a form factor that fit in the palm of a hand. I put it on the table, looked at it. Looked at it again. And then an uncomfortable thought occurred to me. I had ordered it from a Chinese reseller, paid with a credit card, through a completely traceable payment infrastructure, from one of the most centralised and surveilled commercial ecosystems in existence. To build a homelab that would let me escape centralised and surveilled ecosystems.

From time to time, to completely disconnect from everything and everyone, I turn back into a kid and immerse myself in video games. I'm slow, I admit it: a game that would normally take 4-5 hours, I finish in at least quadruple the time. But every now and then, among the depths of Steam, I encounter genuine gems. And last night I finally completed Planet of Lana, a 2023 indie game that had been sitting in my library for months. The plot is straightforward but effective: Lana and Elo, presumably brother and sister, live in a peaceful fishing village built on stilts, where life flows serenely in harmony with nature. But this peace is shattered when a group of robots assault the village, kidnapping some inhabitants including Elo himself. From here begins Lana's odyssey: a journey to the edges of the known world to find and save her brother.
