Talking Points

Rational

• Sometimes, X.org just doesn't want to work
• Esspecially if you are a dumb n00b running Arch
• The terminal will always be there for you.

Applications:

My .bashrc:

• Environment Variables:

export EDITOR=nvim
export PAGER=most
export BROWSER=lynx

export XDG_DATA_HOME="$HOME/.local/share"
export XDG_CONFIG_HOME="$HOME/.config"

PS1: user@hostname:~ (git_branch) $

if [[ $EUID == 0 ]]; then
    export PS1="\[e[1;31m\]\u\[\e[m\]@\[\e[0;32m\]\h\[\e[m\]:\w\$(__git_ps1) # "
else
    export PS1="\[e[1;34m\]\u\[\e[m\]@\[\e[0;32m\]\h\[\e[m\]:\w\$(__git_ps1) $ "
fi

• Aliases:
  • alias vim=nvim
  • alias play=mpv

Productivity ("Window Manager"): tmux

• Provides an easy way of splitting a tty into various panes
• Get multiple workspaces for free with CTL+ALT+F{1,2,3,4,5,6,7}
• All of the tiling window manager, none of the X-it
• Can set up if [ -t 0 ] && [[ -z $TMUX ]] && [[ $- = *i* ]]; then exec tmux; fi in .bashrc in order to have tmux start/stop with your terminal sessiion.

Music: cmus

• Easy library and playlist management
• Dead simple to use (with cmus-tutorial)
  • y to yank songs onto a playlist
  • SPA to select a playlist
  • RET to play a song/playlist
  • TAB to switch between panes

Pictures: fim

• Requires user be in the video group for permission to use the Linux framebuffer

Radio/Video/single audio files: mpv

• Can display video in terminal (badly with libcaca)
• Can actually display video in linux framebuffer (with drm)
• Can handle all of your somafm files/web-video links
• Requires youtube-dl for video

Podcasts/RSS: newsboat/podboat

• Orginizes all of your podcasts and RSS feeds into an easy-to-use ncurses interface
• Can be set up with player "mpv --save-position-on-quit" to save positions on podcasts
• Very convinent for articles, less so for podcasts
• Really needs better integration with something like cmus

Runner Up: podfox

• Can be configured with JSON
• Has better directory structure than podboat, imo
• Tree based structure vs shove everything in ~ by default

Text Editing/Word Processing: neovim/GitX Flavored Markdown/pandoc

• Clean modal editing
• Can export to whatever with pandoc
• Probably not as good as OrgMode if emacs wasn't the HFS+ of text editors

Audio Recording/Post-Processing: ffmpeg

• One alias and three scripts in my .bashrc
  • record: alias record="ffmpeg -f alsa -channels 1 -i hw:1"
  • atrim, top-tail, and anorm: Allows me to quickly spin up a recording and run post processing

function atrim() {
    if [ $1 ]; then
        local in="$1"
    else
        local in="-"
    fi

    if [ $2 ]; then
        local out="$2"
    else
        local out="-f nut -"
    fi

    if [[ $# > 2 ]]; then
        echo "atrim: requires 2 or fewer arguments"
        return 1
    fi

    if [ $2 ]; then echo "atrim: silencing $in and saving to $out..."; fi
    ffmpeg -i $in -af silenceremove=start_periods=1:stop_periods=-1:start_threshold=-50dB:stop_threshold=-50dB:stop_duration=0.75 $out \
        2>/dev/null \
        #1>/dev/null
    if [ $2 ]; then echo "atrim: done"; fi
}

function top-tail() {
    local top="$HOME/project/hpr-notes/template/intro-music-slick0-cc0.flac"
    local tail="$HOME/project/hpr-notes/template/outro-mixed-slick0-manon_fallon-cc0.flac"

    if [ $1 ]; then
        local in="$1"
    else
        local in="-"
    fi

    if [ $2 ]; then
        local out="$2"
    else
        local out="-f nut -"
    fi

    if [[ $# > 2 ]]; then
        echo "hpr-top-tail: requres 2 or fewer arguments"
        return 1
    fi

    if [ $2 ]; then echo "hpr-top-tail: Topping $in with $top and tailing with $tail..."; fi
    ffmpeg -i "$top" -i $in -i "$tail" -vn -filter_complex "
    [0][1]acrossfade=d=1:c1=tri:c2=tri[a01];
    [a01][2]acrossfade=d=1:c1=tri:c2=tri" \
    $out \
        2> /dev/null \
        #1> /dev/null
    if [ $2 ]; then echo "hpr-top-tail: done"; fi
}

function anorm() {
    if [ $1 ]; then
        local in="$1"
    else
        local in="-"
    fi

    if [ $2 ]; then
        local out="$2"
    else
        local out="-f nut -"
    fi

    if [[ $# > 2 ]]; then
        echo "anorm: requires 2 or fewer arguments"
        return 1
    fi

    if [ $2 ]; then echo "anorm: normalizing audio $in and saving to $out..."; fi
    ffmpeg -i $in $(ffmpeg-lh $in) $out \
        #2> /dev/null \
        1> /dev/null
    if [ $2 ]; then echo "anorm: done"; fi

}

Web Browsing: lynx

• Fast and easy text based web browsing
• Can leverage Web 4.0 technologies like Gopher!!
• Some sites break pretty bad...

Email: mutt*

• I didn't really use email very much when I was living on the terminal and now, since I use protonmail, I don't really have an easy way not to use the webmail.

• Trying to find a fix to this. Let me know your thoughts!

• This is the mail client I've heard the most good things about that isn't built into a text editor I can't use
