MySQL(MariaDB) encryption at rest
I’m a big fan of encrypting my data (be that at-rest or in-tranzit) and not because I have some secrets I need to protect but rather I care about my privacy and simply don’t want anybody to find anything about me or the people I care about without me being willing to share that information…

My take on openSUSE
Many many years ago (20 ish) I was playing with all sorts of Linux distributions (peanut, slackware, mandrake, redhat, gentoo, suse and more) and back then I came up with my top 3 preferred Linux distros. My original top 3 looked like this: 1) Slackware; 2) RedHat; 3) Debian; because at that time in terms…

Bye Bye CentOS
Apparently it is the end of CentOS as we know it. Check this out: https://blog.centos.org/2020/12/future-is-centos-stream/ Obviously many ppl right now are in a state of panic considering they liked not having to worry about that layer of their infrastructure (you know, stable os, no major changes between versions of installed software, security patches, etc etc)…

Gentoo on ZFS
… or any other recent enough version of Linux … Everyone seems to be praising ZFS for its advanced features and its reliability and all sorts of other crap and they’re right to do that. The only thing I hate about it is its stupid license which is not GPL compatible which is complicating things…

Gentoo on BTRFS
… or any other recent enough Linux distro for that matter… Been reading a bit about BTRFS and how it’s one of the most advanced file systems out there and how it’s been in development for quite some time and yet it’s still not production ready (some say it is, others say it is not,…

Project – Pickles 2020
This year was a “wonderful” one thanks to Coronavirus (killing tens of thousands of people) and its side effects (lockdown, economy tumbling down, crops not being harvested in time, prices going up for some essentials, people loosing jobs, etc) the preper in me wanted to make sure we get through this winter as healthy as…

MDADM caching
At the request of a friend I’m doing a piece on mdadm (software raid) with caching. Long story short, Raid 4 / 5 / 6 allows using a disk for caching purposes (the disk can be a software raid) To create the array one would run the mdadm command like so: mdadm –create /dev/md0 –level=5…

LVM caching
Many of you are familiar with LVM (I’m sure of that because you must have at least installed some linux distro like something RedHat based with default options and got some partitions on LVM because of that) and maybe some of you are also aware of its “power” (if I can call it like that)…

nscd on CentOS7 is being stupid
Today, while “playing” with my servers to get them to use LDAP for authentication, I realized that nscd on CentOS7 (possibly on other Linux distros as well) is being a bit stupid. Normally to get your Linux system to authenticate against LDAP you’d need to adjust quite a few config files (i.e. /etc/openldap/ldap.conf, stuff in…

Annoying Let’s Encrypt
Let’s Encrypt (aka https://letsencrypt.org/) is a nice way to NOT spend money on SSL certificates for your websites (especially when you’re operating personal sites) BUT at same time it is fairly annoying when you have a setup that’s a bit different than standard ones. In my particular case, I’m running my site on multiple servers…
