On external clipboard issue

• Exit micro

• Avoid copy-paste of big chunk of text from micro to GUI: it may get freezed

bash

https://www.gnu.org/software/bash/

Install new version - for macOS only:

brew install bash
echo /opt/homebrew/bin/bash | sudo tee -a /etc/shells
chpass -s /opt/homebrew/bin/bash

alias cp='rsync -ah --progress'
alias difl='colordiff -u'
alias e=micro
alias gd='git diff --color-words'

EDITOR=micro
PS1='\[\033[35m\]\w $\[\033[0m\] '
VISUAL=$EDITOR

• git commit kept ignoring micro even with GIT_EDITOR var, but git config --global core.editor micro solved the issue

git

https://git-scm.com/

Configure:

cp git/.gitconfig ~/
e ~/.gitconfig
# Update `name` and `email`

vlc

https://www.videolan.org/vlc/

Run and exit VLC to make sure it uses ~/.config/vlc

Configure:

cp vlc/* ~/.config/vlc/

Usage:

• Drag mouse left-right for pause/play
• Drag mouse left or right to skip 10 seconds

On audio not playing after pause/resume

• Tools - Preferences - Audio:
  • Output: ALSA
  • Device: HD-Audio Generic, MODEL Analog Hardware device with all software conversions

smplayer

https://www.smplayer.info/

Why:

• VLC failed to load an audio track from external file, SMPlayer succeeded.

Install:

sudo add-apt-repository ppa:rvm/smplayer
sudo apt update
sudo apt install smplayer smplayer-themes

Configure:

• Options - Preferences
  • Interface
    • Interface - GUI: Mpc GUI
    • Floating control - [v] Show only when moving the mouse to the bottom of the screen
  • Keyboard and mouse
    • Mouse
      • Left click: Play / Pause
      • Right click: Change function of wheel
      • Drag function: Seek (horizontal) and volume (vertical)
    • Mouse wheel functions: Media seeking, Volume control

vsftpd

https://security.appspot.com/vsftpd.html

Why:

• "VLC - Playback - Renderer - TV" requires re-encoding most videos, TV remote control becomes useless, bad UX
• VLC for TV plays videos from removable media with best UX, but you need to insert and safe-eject it on both devices every time
• VLC for TV can play videos on FTP server.
• FTP server is also useful to share files inside of WiFi LAN.

Install:

sudo apt install vsftpd

Configure:

sudo su
e /etc/vsftpd.conf
    local_enable=YES
    write_enable=YES
    chroot_local_user=YES
    xferlog_enable=NO

service vsftpd restart
useradd -rm pub
passwd pub
rm /home/pub/.*
mkdir /home/pub/write
exit

sudo chown -R $USER:pub /home/pub
cd ~/Downloads
ln -s /home/pub
mv $FILES pub/
# These new files will be owned by `$USER:$USER`, readable but not writable for `pub`,
# while `write` dir is still writable for `pub`.

Test:

ifconfig | grep 192.168
ftp 192.168.1.36
ls

• VLC for TV - Add server to Favorities - the server added - play videos!
• If VLC for TV fails to play some videos via FTP, then install "X-plore" app for TV, connect to the same FTP server, play videos, or copy them to TV's internal storage, and play them with VLC for TV

docker

https://www.docker.com/
