I have more and more big files to transfer between my end user devices (laptop, mobiles, ...). The goal of this blog is to compare cpdup and rsync to synch files between my OpenBSD laptop and my NAS. Today, files I'm managing are bigger and bigger. For example, with modern camera I often have +500 photos to transfer which represent +6GB of data. Moreover, I'm an heavy user of hardlinks, so I want to make sure all my hardlinks are correctly reproduced on the NAS.

In a post of 2016 I explained how to build a Read-Only OpenBSD machine. Because in the recent OpenBSD systems we have new components, this post will update the situation. I remind that a read-only machine is a machine where most filesystems are read-only. As consequence you can cut power of the machine without damaging the filesystems. Personally, I'm using such system for my firewalls and my hifi OpenBSD system.

On an old machine running and old BSD OS, I must trigger an email is some keywords are coming in a log file. since this is a very old machine, installation of packages is no more possible. This blog post will show a simple way I've did it with only shell script

I'm using a brand new laptop (T14s) with a wifi driver not supported by several BSD systems. So, the workaround is to install a VM host and run your preferred OS inside a VM This blog post will show you how this impact performances
