remounting with read write rights

• I booted into windows via the external SSD and searched for a file on my second internal disk
• than went back to linux and had no writing rights on this drive, the following command solved it:
• sudo mount -o remount,rw '/media/hisfantor/data/'
• in which /media/hisfantor/data/ is my mount point

rubiks cube

• he wrote a program to simmulate a rubiks cube with variable size
• the program can simulate and solve cubes up to 101x101x101 (your PC hardware is the limiting factor)
• video: https://www.youtube.com/watch?v=IM2czqavlWM
• code: https://github.com/Code-Bullet/RubiksCubeAI
• IDE: https://processing.org/download/
• L to rotate the cube with your mouse space to start/stop scrambling/solving

git prompt²

• download it here and put it in a file in your home directory
• ~/.git-prompt.sh
• then open your ~/.bashrc and put in:

source ~/.git-prompt.sh
export PS1="\[\033[36m\]\u\[\033[m\]@\[\033[32m\] \[\033[33;1m\]\w\[\033[m\] (\$(git branch 2>/dev/nul    l | grep '^*' | colrm 1 2)) \$ "

• the second line will change your command-line prompt to:
• [user]@ [file path] ([git branch]) $

pulseaudio shortcuts³

• first I recognised that pavucontrol and pulseaudio are the same thing… I thought they were different because my soundkeys stopped working when I opend pavucontrol
• my old settings:

bindsym XF86AudioRaiseVolume exec --no-startup-id pactl set-sink-volume 0 +5% #increase sound volume4 
bindsym XF86AudioLowerVolume exec --no-startup-id pactl set-sink-volume 0 -5% #decrease sound volume 
bindsym XF86AudioMute exec --no-startup-id pactl set-sink-mute 0 toggle # mute sound

new settings:

bindsym XF86AudioRaiseVolume exec --no-startup-id amixer -D pulse sset Master 5%+ #increase sound volume
bindsym XF86AudioLowerVolume exec --no-startup-id amixer -D pulse sset Master 5%- #decrease sound volume
bindsym XF86AudioMute exec --no-startup-id amixer -D pulse set Master 1+ toggle # mute sound

alsamixer

• seems to work great (all in my ~/config/i3/config)
