Linux Snippets⚑

• New: Rotate image with the command line.

  If you want to overwrite in-place, mogrify from the ImageMagick suite seems to be the easiest way to achieve this:

  mogrify -rotate -90 *.jpg
  
  mogrify -rotate 90 *.jpg
  

• New: Configure desktop icons in gnome.

  Latest versions of gnome dont have desktop icons read this article to fix this

mkdocs⚑

• New: Center images.

  In your config enable the attr_list extension:

  markdown_extensions:
    - attr_list
  

  On your extra.css file add the center class

  .center {
      display: block;
      margin: 0 auto;
  }
  

  Now you can center elements by appending the attribute:

  ![image](../_imatges/ebc_form_01.jpg){: .center}
  

Wireguard⚑

• New: Improve logging.

  WireGuard doesn’t do any logging by default. If you use the WireGuard Linux kernel module (on kernel versions 5.6 or newer), you can turn on WireGuard’s dyndbg logging, which sends log messages to the kernel message buffer, kmsg. You can then use the standard dmesg utility to read these messages. Also, many Linux systems have a logging daemon like rsyslogd or journald that automatically captures and stores these messages.

  First, enable WireGuard dyndbg logging with the following commands:

  modprobe wireguard
  echo module wireguard +p > /sys/kernel/debug/dynamic_debug/control
  

  Once you do that, you’ll be able to see WireGuard log messages in the kernel message facility, if your system is set up with rsyslogd, journald, or a similar logging daemon. With rsyslogd, check the /var/log/kern.log or /var/log/messages file. With journald, run journalctl -ek.

• New: Add the not by AI badge.

  Not by AI is an initiative to mark content as created by humans instead of AI.

  To automatically add the badge to all your content you can use the next script:

  echo "Checking the Not by AI badge"
  find docs -iname '*md' -print0 | while read -r -d $'\0' file; do
      if ! grep -q not-by-ai.svg "$file"; then
          echo "Adding the Not by AI badge to $file"
          echo "[![](../img/not-by-ai.svg){: .center}](https://notbyai.fyi)" >>"$file"
      fi
  done
  

  You can see how it's used in this blog by looking at the Makefile and the gh-pages.yaml workflow.
