which architectures?
<SilverFox>
UmbralRaptop, scishow just put out a video about TMT Thirty Metre Telescope
<B787_300>
might need to get egg to translate some of it
<UmbralRaptop>
hrm
<B787_300>
also has surface errors of the main mirror in there
<B787_300>
this thing still makes no sense to me... https://en.wikipedia.org/wiki/Large_Zenith_Telescope ... oh lets spin a pan of liquid mercury to make a mirror, but we can only look straight up at whatever is directly over the site
<galois>
[WIKIPEDIA] Large Zenith Telescope | "The Large Zenith Telescope (LZT) was a 6.0-meter diameter liquid mirror telescope located in the University of British Columbia's Malcolm Knapp Research Forest, about 70 km (43 mi) east of Vancouver, British Columbia, Canada. (North of Maple Ridge.) It was one of the largest optical telescopes in the..."

I guess I could bug colorlessfermion about the legend and axes on those graphs
<B787_300>
or hunt and peck at a russian keyboard to put it into G Translate
<UmbralRaptop>
Apparently the bars are observers, operators, and theoretical, respectively

glares at the weather percent for only having 4 months, but I guess other reports exist

B787_300: I don't speak ru

B787_300: ask whitequark maybe
<whitequark>
which diagram
<oeuf>
<B787_300> UmbralRaptop: slide 3? ПогодаКоличество часов
<whitequark>
the legend says, from top to bottom: Observers; Operators; Theoretical
<whitequark>
the Y axis is in observation time, hours
<UmbralRaptop>
the axes make sense, though I'm not 100% clear on what they're measuring and if it corresponds to eg: science time, engineering time, and total time w/o maintenance and weather losses

<sortiecat> @qntm The 2010's did pretty well well by being a second longer than the 2000's but four seconds shorter than the 19… https://t.co/H8iTH9GUAn

wait a minute, I dont get it

whitequark: note that this means that if you use posix timestamps as they are defined before 1972, your rate changes (I think in practice people ignore what the posix wording says and just extrapolate at constant TAI offset)

(arguably if you have decent second-level timestamps from 1970 you probably know better than to store your data in that ambiguous formats)

UmbralRaptop: JD
<oeuf>
UmbralRaptop: well yes but JD in which timescale
<UmbralRaptop>
aaaa
<oeuf>
(the IAU stated that the default is TT unless otherwise specified, right?)
<oeuf>
(can't remember which resolution)
<UmbralRaptop>
Sounds right?
<oeuf>
and obviously JD for UTC is probably nonsense
<UmbralRaptop>
maybe. JD for TAI definitely is
<oeuf>
UmbralRaptop: what? it's perfectly well-defined for TAI
<oeuf>
for any continuous timescale really
<UmbralRaptop>
oh

was thinking more of rotational errors
