+## Problem
+While the [hyperref](https://www.ctan.org/pkg/hyperref) package provides the `\\url{}` command it doesn't handle line breaks well.
+
+## Solution
+Use the package [xurl](https://www.ctan.org/pkg/xurl).

+Installing security updates is very important. Especially on a server that is not accessed on a daily basis.
+This tutorial covers the basics for setting up unattended-upgrades on any Debian-based Linux distribution.
+## Update the system
+```
+sudo apt update && sudo apt upgrade
+```
+## Install unattended-upgrades
+```
+apt install unattended-upgrades
+```
+```
+dpkg-reconfigure unattended-upgrades

+title = 'Basic Doom Emacs Commands'
+type = 'post'
+tags = ['Emacs']
+++
+
+This is basically just a collection of various commands I discovered while learning to use Doom Emacs. 
+All Sources will be listed at the bottom of this page.
+
+Also. This side does not provide a lot of explanation regarding the function of the commands. 
+It is just intended as a cheat sheet. 
+Updates/ Changes **will** be added to this post.
+
+# Navigation
+## Workspaces
+- switch between workspaces: '**SPC TAB .**'
+- load workspace: '**SPC TAB l**'
+- create new workspace: '**SPC TAB n**'
+- rename workspace: '**SPC TAB r**'
+- save workspace: '**SPC TAB s**'
+- select project for workspace: '**SPC p p**'
+### File Switching inside Workspaces
+- switch to file within current project: '**SPC SPC**'
+    - '**SPC .**' provides the save functionality but can also search outside the current project
+- switch to buffer within current project: '**SPC ,**'
+- switch to a buffer outside the current project: '**SPC b B**'
+- load recently viewed file: '**SPC fr**'
+
+## Finding Text
+- search all files in the current project: '**SPC sp**'
+- search inside the current buffer: '**/**' (normal Vim navigation)
+### Moving to Text
+- jump to line (faster then relative line numbers): '**gsj**'
+- '**s**' and two chars to jump to the nearest match
+    - '**S**' to jump backwards
+    - '**,**' or '**;**' to cycle through the matches (forwards/ backwards)
+         
+**NOTE:** this navigation can be combined with (almost) all of the standard Vim commands (e.g. '**vs\\<chars\\>**' visualizes all the text to the nearest match for \\<chars\\>)
+
+## Source Code
+- go to definition: '**gd**'
+- list references: '**gD**'
+### Fancy Delete
+**NOTE:** all these commands should also work for 'change' ('**c**')
+- delete inside the same indent (e.g. *function* of if statement): '**dii**'
+- delete inside the same indent + line above (e.g. *complete* if statement in python): '**dik**'
+- delete inside the same indent + line above and below (e.g. *complete* if statement in java): '**dij**'
+
+## Compilation Errors
+- next and previous flycheck error: '**\\]e**' and '**\\[e**'
+- list current errors: '**SPC c x**'
+
+# Miscellaneous
+- compile: '**SPC p c**'
+- open [Magit](https://magit.vc/): '**SPC gg**'
+- comment/ uncomment a line: '**gcc**'

+++
+
+By using the `pdfimages` command included in most Linux distributions it is easy to extract all pictures included in a PDF document.
+Instructions on how to use the command can be found [here](https://www.xpdfreader.com/pdfimages-man.html).
+
+**Note:** the target directory for the extracted images must be created before executing the command, else it will just throw errors.

+    ```
+1. Install open source drivers [libspnav](https://archlinux.org/packages/extra/x86_64/libspnav/) and [spacenavd](https://aur.archlinux.org/packages/spacenavd)from the AUR (propriatary drivers are very old)

+1. test the setup by running the daemon manually (test programs like [FreeCAD](https://www.freecad.org/) might need to be restarted)
+    ```bash
+    spacenavd -v -d
+    ```
+1. the daemon is provided in the form of `spacenavd.service` by the [spacenavd](https://aur.archlinux.org/packages/spacenavd) package and can be started or enabled with [systemctl](https://wiki.archlinux.org/title/Systemctl)
