ADDITIONAL TOOLS/APPS FOR TO MAKE THE FUN

Syncthing

• Add release key:

sudo mkdir -p /etc/apt/keyrings && \
sudo curl -L -o /etc/apt/keyrings/syncthing-archive-keyring.gpg https://syncthing.net/release-key.gpg

• Add stable channel to sources

echo "deb [signed-by=/etc/apt/keyrings/syncthing-archive-keyring.gpg] https://apt.syncthing.net/ syncthing stable" | sudo tee /etc/apt/sources.list.d/syncthing.list

• Update & Install Syncthing:
  
• Web UI configure is mostly self-taught, check settings!

sudo apt update && sudo apt install syncthing

• Make auto-start with system (replace myuser with username)

systemctl enable [email protected]
systemctl start [email protected]

7zip

Super complicated:

sudo apt install p7zip-full p7zip-rar

to unzip with directories:

7z x filename

install Caffeine: ~~~~~~~~~~~~~~~~~~~

Caffeine is used to PREVENT sleep! (after all the working getting sleep!)

sudo apt install caffeine

and then in the startup-apps app, add:

/usr/bin/caffeine-indicator

PDF tools

Convert PDF to individual image files:
(Example below will convert “source.pdf” to image-01.png, image-02.pdf, etc.)

pdftoppm -png source.pdf images

If using paint, manually convert .png to .bmp

• Then, to go back to compiled PDF:
  
• (images(1-3).bmp means: images1.bmp images2.bmp images3.bmp)
• “-s n%xn%” is an optional size mod

img2pdf -s 64%x64% -o destination.pdf images[1-3].bmp

Additional tools for manipulating PDFs

• ”Combine bon1.pdf and bon2.pdf, to make bon12.pdf”
  
• (these both have the same result)

pdftk bon1.pdf bon2.pdf cat output bon12.pdf

pdftk bon[12].pdf cat output bon12.pdf

• “Combine bon1, then page 3 of bon3, then bon2, then pages 6-8 of bon3”
  

pdftk A=bon1.pdf B=bon2.pdf C=bon3.pdf cat A C3 B C6-8 output bone.pdf
