One day you wake up, guardi un vecchio dispositivo che sedimenta in un cassetto da tanti anni – nel mio caso una telecamera IP con un glorioso ma ostinato chip HiSilicon hi3510 – e decidi che è arrivato il momento di fare le cose per bene. You tell yourself: “No more proprietary clouds, Read more
We have reached the last chapter of our Btrfs trilogy. After securing your data and scheduling backups, today we talk about how to optimize every single byte on the disk. If you think that space is a finite resource, Btrfs will change your mind thanks to transparent compression and Read more
In the previous post we saw how to make our system resilient “on site” using RAID and snapshot. But if the PC explodes or the server is stolen, local snapshots are useless. Today we make the leap in quality: Let's learn how to use Btrfs Send and Receive. Forget rsync e Read more
If you run a Linux server or workstation, the file system is not just a place where “park” file, but your first line of defense against data corruption. Today we talk about Btrfs, un file system copy-on-write (CoW) which offers native tools to manage integrity and redundancy. Read more
Anyone who runs a DIY server or home NAS has found themselves in that panic situation at least once “from missing label”, staring four identical drives into the case and praying you don't take out the wrong one during a migration or failure. If you have a mixed setup with a pool Read more
Making a backup is essential, but knowing how to restore in case of disaster is what saves your evening (or live). The process is the exact opposite of backup: we take the archive from our PC and “let's inject” directly into the Dwarf filesystem via SSH. Total restoration of Read more
In the previous post we saw how the Dwarf MOD is much more than a simple multi-effect: is a real Linux audio server. HE, come me, you've spent hours poking around in your browser to create the perfect signal chain, the last thing you want is to lose everything due to a mistake Read more
I am chronically forgetful, stratospheric, abysmal. I don't remember anything and above all I don't remember what I should at the moment I need it. Fortunately, the history command comes to my aid, which isn't actually a command at all (it is not present among the executable programs), but it is Read more
Anyone who follows these pages knows that I have a weakness for solutions that combine IT tinkering with music production. I recently got my hands on a used Dwarf MOD, and after the first test sessions with my guitar and a 150W active speaker, I understood that Read more
Today we talk about an aspect that is deeply felt by all musicians, especially non-professionals. We have always looked for the perfect compromise between quality and cost, with very variable results depending on what we obtain in terms of hardware and software. If you want to skip the relevant block Read more
