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

systemctl, journalctl breaking bad

Since systemctl and journalctl are bad by breaking scrolling by default (using a pager).

Do this as root to become sane again:
echo SYSTEMD_PAGER= >>/etc/environment

Log out and back in.

My comment on the video "The Quantum Experiment that Broke Reality", belong on here as well.
- It is about the double slit experiment.

You might be able to predict the "landing point" if you knew the state of the peaks in the "waving" screen, the slits and the buckyballs- how they waved (could "look" something like water in near zero gravity). ..And you might be able to "set" the states using oscillating magnetic fields.
