I saw a post recently about someone setting up parental controls -- screentime, blocked sites, etc. -- and it made me wonder.

In my childhood, my free time was very flexible. Within this low-pressure flexibility I was naturally curious, in all directions -- that meant both watching brainteaser videos, and watching Gmod brainrot. I had little exposure to video games other than Minecraft which ran poorly on my machine, so I tended to surf Flash games and YouTube.

Strikingly, while watching a brainteaser video, tiny me had a thought:

I'm glad my dad doesn't make me watch educational videos like the other kids in school have to.

For some reason, I wanted to remember that to "remember what my thought process was as a child" so that memory has stuck with me.

Onto the meat: if I had had a capped screentime, like a timer I could see, and knew that I was being watched in some way, I'd feel pressure. For example,

10 minutes left. Oh no. I didn't have fun yet. I didn't have fun yet!!

Oh no, I'm gonna get in so much trouble for watching another YTP...

and maybe that pressure wouldn't have made me into an independent, curious kid, to the person I am now. Maybe it would've made me fearful or suspicious instead. I was suspicious once, when one of my parents said "I can see what you browse from the other room" -- so I ran the scientific method to verify if they were. (I wrote "HI MOM" on Paint, and tested if her expression changed.)

So what about now? Were we too free, and now it's our job to tighten the next generation? I said "butthead" often. I loved asdfmovie, but my parents probably wouldn't have. I watched SpingeBill YTPs (at least it's not corporatized YouTube Kids).

Or differently: do we watch our kids without them knowing? Write a keylogger? Or just take router logs? Do we prosecute them like some sort of panopticon, for their own good?

Or do we completely forgo this? Take an Adventure Playground approach?

Of course, I don't expect a one-size-fits-all answer. Where do you stand, and why?

Git cheat sheets are a dime-a-dozen but I think this one is awfully concise for its scope.

• Visually covers branching (WITH the commands -- rebasing the current branch can be confusing for the unfamiliar)
• Covers reflog
• Literally almost identical to how I use git (most sheets are either Too Much or Too Little)

What was your last RTFM adventure? Tinker this, read that, make something smoother! Or explodier.

As for me, I wanted to see how many videos I could run at once. (Answer: 60 frames per second or 60 frames per second?)

With my sights on GPUizing some ethically sourced motion pictures, I RTFW, graphed, and slapped on environment variables and flags like Lego bricks. I got the Intel VAAPI thingamabob to jaunt by (and found that it butterized my mpv videos)

$ pacman -S blahblahblahblahblahtfm
$ mpv --show-profile=fast
Profile fast: 
 scale=bilinear
 dscale=bilinear
 dither=no
 correct-downscaling=no
 linear-downscaling=no
 sigmoid-upscaling=no
 hdr-compute-peak=no
 allow-delayed-peak-detect=yes
$ mpv --hwdec=auto --profile=fast graphwar-god-4KEDIT.mp4
# fucking silk

But there was no pleasure without pain: Mr. Maxwell F. N. 940MX (the N stands for Nvidia) played hooky. So I employed the longest envvars ever

$ NVD_LOG=1 VDPAU_TRACE=2 VDPAU_NVIDIA_DEBUG=3 NVD_BACKEND=direct NVD_GPU=nvidia LIBVA_DRIVER_NAME=nvidia VDPAU_DRIVER=nvidia prime-run vdpauinfo
GPU at BusId 0x1 doesn't have a supported video decoder
Error creating VDPAU device: 1
# stfu

to try translating Nvidia VDPAU to VAAPI -- of course, here I realized I rtfmed backwards and should've tried to use just VDPAU instead. So I did.

Juice was still not acquired.

Finally, after a voracious DuckDuckGoing (quacking?), I was then blessed with the freeing knowledge that even though post-Kepler is supposed to support H264, Nvidia is full of lies...

SO. What was your last RTFM adventure?

I have a little helper command in ~/.zshrc called stfu.

stfu() {
    if [ -z "$1" ]; then
        echo "Usage: stfu <program> [arguments...]"
        return 1
    fi

    nohup "$@" &>/dev/null &
    disown
}
complete -W "$(ls /usr/bin)" stfu

stfu will run some other command but also detach it from the terminal and make any output shut up. I use it for things such as starting a browser from the terminal without worrying about CTRL+Z, bg, and disown.

$ stfu firefox -safe-mode
# Will not output stuff to the terminal, and
# I can close the terminal too.

Here’s my issue:

On the second argument and above, when I hit tab, how do I let autocomplete suggest me the arguments and command line switches for the command I’m passing in?

e.g. stfu ls -<tab> should show me whatever ls’s completion function is, rather than listing every /usr/bin command again.

# Intended completion
$ stfu cat -<TAB>
-e                      -- equivalent to -vE

-u                      -- ignored  

# Actual completion
$ stfu cat <tab>
...a list of all /usr/bin commands
$ stfu cat -<tab>
...nothing, since no /usr/bin commands start with -

(repost, prev was removed)

EDIT: Solved.

I needed to set the curcontext to the second word. Below is my (iffily annotated) zsh implementation, enjoy >:)

stfu() {
  if [ -z "$1" ]; then
    echo "Usage: stfu <program> [arguments...]"
    return 1
  fi

  nohup "$@" &>/dev/null &
  disown
}
#complete -W "$(ls /usr/bin)" stfu
_stfu() {
  # Curcontext looks like this:
  #   $ stfu <tab>
  #   :complete:stfu:
  local curcontext="$curcontext" 
  #typeset -A opt_args # idk what this does, i removed it

  _arguments \
    '1: :_command_names -e' \
    '*::args:->args'

  case $state in
    args)
      # idk where CURRENT came from
      if (( CURRENT > 1 )); then
        # $words is magic that splits up the "words" in a shell command.
        #   1. stfu
        #   2. yourSubCommand
        #   3. argument 1 to that subcommand
        local cmd=${words[2]}
        # We update the autocompletion curcontext to
        # pay attention to your subcommand instead
        curcontext="$cmd"

        # Call completion function
        _normal
      fi
      ;;
  esac
}
compdef _stfu stfu

Deduced via docs (look for The Dispatcher), this dude's docs, stackoverflow and overreliance on ChatGPT.

EDIT: Best solution (Andy)

stfu() {
  if [ -z "$1" ]; then
    echo "Usage: stfu <program> [arguments...]"
    return 1
  fi

  nohup "$@" &>/dev/null &
  disown
}
_stfu () {
  # shift autocomplete to right
  shift words
  (( CURRENT-=1 ))
  _normal
}
compdef _stfu stfu
