On my desk I have two screens -- one off to the side for movies, TV, etc and my main in front. Sometimes I find myself wanting subtitles on my main screen. The main issue I've found, at least with macOS, is that the SRT players suck.

I figured, why not just generate a tiny black video with embedded subtitles?

ffmpeg -i subs.srt -t 3:00:00 -s 40x10 -f rawvideo -pix_fmt rgb24 -r 25 -i /dev/zero subs.mpeg

Set the ratio to be super small without being too small. This video is 40px by 10px and the video only takes a few seconds to generate. For me, this generated at ~850x speed.

From there, jack up the subtitle font size and shift it up a little bit so nothing gets cut off. This also works really well with tiling window managers.

Some of you have read the Typesetting Markdown blog series (https://dave.autonoma.ca/blog/). The plan was to finish the last two parts with Annotated Text (basically markup for Markdown) and Figure Drawing (MetaPost); however, people have asked for a post on Markdown to EPUB, others have asked for high-quality PDF theme templates using ConTeXt, and some have requested rendering Markdown into HTML.

Within the realm of Markdown, digital documentation, typesetting with ConTeXt, R, externalized interpolated strings, and bash scripting, what would interest you for the next post in the series?

(Please flip through the blog series to see the topics that have been covered.)

On lobste.rs I found link to an article from Vidar Holen, the author of shellcheck. He made a fork bomb that is really interesting. Here's the bomb:

DO NOT RUN THIS.

eval $(echo "I<RA('1E<W3t`rYWdl&r()(Y29j&r{,3Rl7Ig}&r{,T31wo});r`26<F]F;==" | uudecode)

This may look pretty obvious, but it's harder than you think. I fell for it. ^twice. Can you find out how this bomb works?

Warning: executing the bomb will slow down your computer and will force you to restart.
You can limit impact of the fork bomb by setting FUNCNEST.

export FUNCNEST=3

Have fun!

I use this constantly, it just plays music by file name, specifically matching *NAME* with case-insensitivity. Requires bash 4.something.

# play -ln SONGS ...
# -l don't shuffle
# -n dry run
mpv_args="--no-audio-display --no-resume-playback \
          --msg-level=all=status --term-osd-bar"
shopt -s globstar nullglob nocaseglob

shuffle=true
dry=false
while [[ "$1" == -* ]]; do
    if [[ "$1" == "-l" ]]; then 
        shuffle=false
    elif [[ "$1" == "-n" ]]; then
        dry=true
    fi

    shift 1
done

if [[ "$shuffle" == true ]]; then
    mpv_args="--shuffle $mpv_args"
fi

songs=()
while [[ "$#" != 0 ]]; do
    songs+=( ~/music/**/**/*"$1"*.* ) # change this to match your music directory layout
    shift 1                                               # could probably use find instead
done

if [[ "$dry" == true ]]; then
    if [[ "$shuffle" == true ]]; then
        printf "Shuffle mode is on\n"
    fi

    for song in "${songs[@]}"; do
        printf "$song\n"
    done
  
    exit
fi

if [[ ${#songs[@]} != 0 ]]; then
    mpv $mpv_args "${songs[@]}"
fi

I make no claims to the quality of this but it works!
