 My «captain» logs

Last edition: Monday the 3rd June, 2024

Purpose of this page

As a captain of a ship, the administrator of an operating system is responsible of everything happening to the ship. It's the captain duty, as the administrator.

Since Gentoo is kind of very powerful, related to most Linux distribution or other OS, it's very easy to do things and forget them right away.

Specially when the captain is ADHD. If life was a game, a RPG, I would have a gigantic malus in intelligence because I can't brain properly.

That's why this page comes into existence. I lost time too many often because I forgot something I did before, as energy and mental sanity, to me as other.

Here will be reported major operations of my system. By date and time, explaining what was done and for what purpose I did wanted to do it.

If by any chance I redirect you on this page, it is because it should contains informations useful to help me. See this as… a (back)log of my doing.

This page is a test

For now, it'll take care only of my main machine, called Mephistopheles, having the list of hardware and parameters, configuration and such.

This page could contains «uninteresting» stuff

Because my memory is clearly bad, I even forget where I puts my note. Since this page is kind of related, will list what I want to do (later) or is a work in progress, it's for me, really, but feel free to take a look.

Mephistopheles

Main workstation, future server/workstation (work in progress).

Goals to achieve, stuff to do

Non-exhaustive list, specially needed for my own usage of course, it's just here because otherwise I will forget where I noted these stuffs, as usual !

Security

Sandbox some apps

• Runs into sandbox some applications as Firefox, Thunderbird, because they are opens door to be hacked !

I did not even tried for now :).

Monitoring the system

• Add monitoring system to manage more deeply what's going on.

Data

• Resetup backups with xfsdump (not only)

I'm just lazy, will do very soon.
