#TIL: The 27th Amendment to the US Constitution took over 200 years to pass. The push to get it done came about because of a bad grade on a college paper. https://www.npr.org/2017/05/05/526900818/the-bad-grade-that-changed-the-u-s-constitution [www npr org]

#TIL: Hill Sphere ( Roche Sphere ) https://en.wikipedia.org/wiki/Hill_sphere ... part of the late night explorations.
This is something I had thought about before, but not in sufficient detail to have the concept crystallize.

#TIL: “Ukraine” is the English transliteration of “Україна”, pronounced oo-CRAY-yee-nah
I just assumed that we pronounced it the same as they did.
Also, there used to be some Ukrainian families (refugees) living nearby in the 1990s. I really enjoyed the sound of their language when they spoke to one another. I have not heard it since then.

Those commercials were years before I ever even heard of Garth Brooks. Wow. I'm surprised. #TIL also.
(For me, if I'm ever looking back trying to figure out what I learned today, http://moodpoint.com/lyrics/garth_brooks/dr_pepper_commercial.html ... see thread )

#TIL about #jq ... like #awk, #sed, #grep, except specialized for #JSON data. https://stedolan.github.io/jq/

Interesting conversation about Western Digital "Red" HDDs for #NAS devices https://freeradical.zone/@tek/104037571132363249 ... he links to [1] in the OP.
"Western Digital, Seagate and Toshiba have begun selling SMR drives without labeling them as such, thus revealing a large controversy, as SMR drives are much slower in some circumstances than PMR drives.[9] These practices were used to be in both data storage-dedicated (for servers, NASes and cold storage) and consumer-centric HDDs." [2]
Also, #TIL: SMR (Shingled magnetic recording) [3], PMR (Perpendicular magnetic recording) .
The OP explains why this is an issue in [4] and [5] and [9].
Also, #TIL (Today I learned) the terms: LMR (longitudinal magnetic recording [6], and PMR (Perpendicular magnetic recording) [7] ... I already knew generally about both processes, but did not have specialized terminology for them. (CMR [8] is a rename of PMR.)

All the NAS units I've purchased (possibly excepting #sonOne's, since I did not buy drives for him) also got WD Red NAS drives. Possibly they were older PMR/CMR drives, but since WD did not properly label their products, I do not know.

#TIL: SETI@Home is "going into hibernation" ... long ago, I had BOINC running on a couple of computers, attached to SETI@Home and some other projects.
"SETI@home hibernation
On March 31, the volunteer computing part of SETI@home will stop distributing work and will go into hibernation.
We're doing this for two reasons:
1) Scientifically, we're at the point of diminishing returns; basically, we've analyzed all the data we need for now.
2) It's a lot of work for us to manage the distributed processing of data. We need to focus on completing the back-end analysis of the results we already have, and writing this up in a scientific journal paper.
However, SETI@home is not disappearing. The web site and the message boards will continue to operate. We hope that other UC Berkeley astronomers will find uses for the huge computing capabilities of SETI@home for SETI or related areas like cosmology and pulsar research. If this happens, SETI@home will start distributing work again. We'll keep you posted about this.
If you're currently running SETI@home on your computer, we encourage you to attach to other BOINC-based projects as well. Or use Science United and sign up to do astronomy. You can stay attached to SETI@home, of course, but you won't get any jobs until we find new applications.
We're extremely grateful to all of our volunteers for supporting us in many ways during the past 20 years. Without you there would be no SETI@home. We're excited to finish up our original science project, and we look forward to what comes next.
