Aphantasia

While it is clearly a trauma response.

My comment on Wired UK's video on Aphantasia (https://youtu.be/Xa84hA3OsHU).

- I wonder if some of these people have once done something that they regretted so much that aphantasia was a necessary defense mechanism - and at the same time somewhat immunizing them from regret in the future by enabling them to dissociate more easily.

Myopia

What is causing progression of myopia?

Myopia is getting widespread (check South Korea stats).
What major changes have happened that could cause this?
- Less exercise and and more staring at tiny screens -are obvious ones - but how?

From reading discussions on ophthalmology forums and articles on pubmed, apparently the cause is not:
- Overcorrecting..
- Undercorrecting (which includes not correcting)..
- Peripheral defocus (some reasonably new lenses are using technologies to do this and is getting closer/slowing progression)..


"Light" -fits all the facts so far, so maybe getting enough light into the peripheral could do the trick (and more exercise/daylight/etc..).

Dark matter

Since particles pop into existence from vacuum fluctuations, I believe some of them can create a bit of gravity upon decaying by releasing smaller particles like neutrinos -or even EM.

Boot openSUSE Tumbleweed faster

Change compression method for initrd, as root:
echo 'compress="cat"' >/etc/dracut.conf.d/99-compress.conf
dracut --force

And if you're not using YaST to configure network setup, Networkmanager might speed up boot a bit compared to Wicked, as root:
systemctl enable NetworkManager && systemctl disable wicked

Fix Gnome (/Xorg) 3.24/3.26 stutter on NVIDIA

..By recompiling mutter without threaded GL sync.
From the source tree:

1. cd mutter-3.26.1/
2. cp src/backends/x11/meta-renderer-x11.c src/backends/x11/meta-renderer-x11.c.orig
3. sed 's/cogl_xlib_renderer_set_threaded_swap_wait_enabled (cogl_renderer, TRUE/cogl_xlib_renderer_set_threaded_swap_wait_enabled (cogl_renderer, FALSE/' -i src/backends/x11/meta-renderer-x11.c

Now compile, install and restart it..

The problem arise from a timing issue.

What it all boils down to.

The only thing that exists, is pressure.

Re-encode audio to AAC, in a bunch of mkv files..

..as fast as bandwidth to the fileserver can allow, running encodes in parallel up to amount of processors. AAC seems compatible with HW decoders everywhere + also with Chromebooks, which invited me to create this:

#!/bin/bash -e

TEMP=/fast/temp
DOWN=2 #allow 1 more than max 'uploads' to keep encoding busy
UP=1 #limit in order to write in a streamlined fashion rather than trashing NAS/FS, due to potential race condition +1 might happen

[[ -z $1 ]] && echo "Usage: $0 <file> [file] [file].." && exit 0
FAACS=$(nproc)
PGID=$$ #limit scope for pgrep
cd "$TEMP"

sleeprnd() { echo $((RANDOM % ($(pgrep -xcg $PGID sleep)+1) +1)); } #random secs between 1 .. amount of sleep processes we're running
waitcount() { while [[ $(pgrep -xcg $PGID $1) -ge $2 ]]; do sleep $(sleeprnd); done; }
re-encode() {
        ORIG="$1"
        BASE="$(basename "$ORIG" .mkv)"
        LOCAL="$BASE"_orig.mkv
        DEST="$(dirname "$ORIG")"/"$BASE"_aac.mkv
        #now wait for ample space to be available @TEMP
        until [[ $(df --output=avail "$TEMP" | tail -n 1) -gt $(( 7 * $(du "$ORIG" | sed -e 's/\t.*//g') )) ]]; do sleep $(sleeprnd); done
        waitcount cp $DOWN; cp -v "$ORIG" "$LOCAL"
        mkvmerge --no-audio "$LOCAL" -o "$BASE"_noaudio.mkv
        for TRACK in $(mkvmerge -i "$LOCAL" | grep ': audio' | sed -e 's/:.*//g' -e 's/.* //g'); do
                mkvextract tracks "$LOCAL" $TRACK:"$BASE"_audio
                waitcount faac $FAACS; ffmpeg -v 0 -i "$BASE"_audio -f wav - \
                        | faac -b 160 - -o "$BASE"_audio_$TRACK.aac &>/dev/null
        done
        mkvmerge "$BASE"_noaudio.mkv "$BASE"_audio_*.aac -o "$BASE".new.mkv
        rm "$BASE"_*
        waitcount cp $UP; cp -v "$BASE".new.mkv "$DEST"
        touch "$DEST" -r "$ORIG"
        #mv "$DEST" "$ORIG"
        echo "$ORIG" >>/dev/shm/ramdisk/log
        rm "$BASE".new.mkv
}

while [[ -n "$1" ]]; do
        re-encode "$1" &
        sleep 1
        shift
done
