GPSD / NTPD / Debian 10 Buster

Posted by xaminmo
I think I finally have my GPS NTP server tweaked. Average deviance yesterday was 0.33ms.
 
Just threw that last adjustment in, and we’ll see tomorrow how it aligns (eg, am I just -0.33 now, or am I close to 0.03 off?)
 
Without the time1 offset, it was getting silently ignored. Obscure.
 
Config is simple once you understand it, but for me, the understanding part was tough.
 
Quick-Reference:
apt update && apt install gpsd ntp ntpdate
ntpdate time.nist.gov
 
Plug in the VK* or uBlox style GPS receiver and put it in a window.
dmesg | grep tty
cat <<‘EOF’ >> /etc/default/gpsd
START_DAEMON=”true”
USBAUTO=”false”
DEVICES=”/dev/ttyACM0″
EOF
systemctl disable gpsd.socket
systemctl enable gpsd.service
systemctl restart gpsd.service
 
cat <<‘EOF’> /etc/ntp.conf

Dream: Time Travel to Isol

Posted by xaminmo
Had a dream where I was time travelling in my dream, and I got to hand our with my grandmother who IRL died when I was 8. Giant hugs were had. I got to see her as a fearless young woman, and she was testing out some roof slats on a shed before putting on the metal. I explained to her the other times I would dream visit as a kid and such, then showed her a bunch of modern technology. Dream grandmother was modelled after an acquaintance of mine who reminds me of her, and is pretty amazing. Dream prompt was probably connected because my IRL diet drug cancellation was due to slight cancer risk, and my maternal grandmother died of cancer (metastic colon cancer in the brain).

Digestion Time of Various Foods

Posted by xaminmo

I am still looking for the raw source of this information, or the methods used to obtain it.

It matches my observations, but without scientific backing, this must be considered anecdotal at best.
