Update wiki on various topics This update is too large, I made too many notes on stuff. Nonetheless, it is very nice to see progress. I've made note revisions on the following topics: - Learning - Writing - Various Linux-related stuff I've yet to start learning illustration but I'll be starting tomorrow for an update how do I keep in mind with those writings. There are still a lot of things to be processed from the backlog with yet more notes on learning but I keep having those perspectives whenever I practice so ehhh... Better have those than nothing? Furthermore, I've also updated the timestamp format. It is pretty simple to update all of the notes with a couple of `sed` calls. Aaaand, I've also changed the way how the assets stored with the folders only leaving it up for the generated files instead of enforcing it on every note. I create more visual aids and managing them is a pain for each note. This restructuring frees me of that burden.

systemd is a big tool for a big system.
Let's explore some of them from a perspective of a wannabe power user.
Update notebook as of 2021-08-07 With the few updates on more learning, writing, and some forward calls for archiving which I'll be jotting down for some ideas soon.

Among other things, it has the following list of features.
- [[id:f1b21fc8-86a5-47cd-b3d8-da6ac7a34427][systemd timers]] which can replace cron for task scheduling.
- [[id:cd5f0d04-d9bb-44e8-a0f2-630ea58c1e94][systemd services]] along with the usual antics of a service manager such as managing dependencies and commands to run when killed.
- [[id:a602f900-cdcf-4090-9278-d5926d80eedc][systemd transient units]] for quickly creating and scheduling one-off services.

- [[id:8505f1f0-f15b-4b04-91fc-12be01913ce6][systemd-boot]] is a bootloader mainly for UEFI-based systems.

* systemd at user-level
Update the notebook The topics I've covered so far for Linux, package managers, archiving, and learning. I also updated some formatting for other notes especially with the command line references.

systemd has the ability to run at user-level empowering the user to manage their own system with their own settings.
It immensely helps separating user-specific settings from the system-wide settings.
systemd looks for the units from certain paths.
You can look for them from the =systemd.unit.5= manual page.
To run systemd as a user instance, simply add a =--user= flag beforehand for =systemctl= and other systemd binaries, if applicable.
