The link works for me.
The older post of course references older civilizations, as it should.

The deadline got pushed out again. Normally that's a good thing, but I front loaded all of my work and worked myself hard to get it done early because of anxiety, when I could have easily dragged it out, even before the deadline got extended.
So now I am just trying to kill time and frankly, I have too much of it at the moment. I'm turning into a gamer, but I'm not really enjoying it.

Being on time is everything to me. I lose sleep when I miss deadlines. Every moment in overtime is anxiety for me, and I live with anxiety all the time anyway. I don't need more, so I don't miss deadlines.
Also, all my work is contract based. I have a business that it all funnels through and with that comes estimates and deadlines. I meet those deadlines or it's my reputation and as I alluded to - my sleep that suffers.
I've tried to depersonalize my projects, and I think I've done a decent job of doing so, but overall I do take pride in doing my best work, and it's important to me.
Sometimes though, all of the above can result in situations like this. It still beats being late.
It's just all the empty time to fill in "workday" now. I'll muddle through, I'd just rather be working.

I hate when it happens. I usually let deadlines go by without a care in the world knowing that most of the times they are ephemeral, but if a deadline is sold to me as super-critical, I work my arse off to meet it and then it's pushed I get royally pissed.

I want to create a program for Astronomical Ephemeris, but I don't know much about it.
My real intention is to understand this software astrolog at this
Any recommendations on some quick tutorials on this topic?

I used to use this one, might give you an idea of what's involved.

Stellarium (stellarium.org) has an observability plugin you might be interested in. I haven't used it, so cannot comment further.

I regularly use Stellarium from Portable Apps website. It is pretty straight forward but user interface is a little difficult at first. When you initially run it, it starts slow but be patient. When it first comes up it will be full screen. If move the mouse to bottom of window a popup will display some options.
Move cursor all the way to left corner. Another vertical menu will pop up. Select the top of the menu to get to the location specification interface. It's tricky, but you can enter your location by city name.
Move cursor to bottom again, horizontal menu comes up. On the right is date and time scroll buttons.
It's a great tool. And I have confirmed its star and moon locations by going outside and observing them.
To end the program hit the power button on far right of lower horizontal menu.

If you have a tracking telescope, Stellarium can control it for you. It is extremely powerful, and good enough for archaeoastronomy work. You can see some of it's archaeoastronomy abilities in the 'Our Forgotten Astronomy' link in my signature, if you are interested in such endeavors.

I do not have a tracking telescope. Glad that Stellarium has such a feature. I have listened to some of your lectures about history, astronomy and religion. Pretty complicated but interesting about the links.
Funny how the stars and our lives can get intermixed. I remember seeing Haley's comet "many moons ago", one of my favorite expressions.
Thanx

My favorite will always be the night I got to watch the Northern Lights almost all night long. I've only seen them that once - Incredible!

I have seen Aurora Borealis multiple times. In Canada and U.S. The last were huge white curtains with tinge of green that lasted for hours. I was told it happens quite often at northerly latitudes above 50 deg. BTW Aurora Australis is the southern latitude version. Not seen those.
Enjoyed your discussion on the potential roots of the Samson story.

Mine were green and red sheets, dancing all night. Little to no white. It was amazing!

|

yup, you don't easily forget it. Amazing that it is very natural.
I guess if you see every night you are lucky but not always as amazed.

I have written several ephemerides over the years, the first being for an HP75C, using the 'Low-precision formulae for planetary positions' by van Flandern and Pulkkinen (Astrophysical Journal Supplement Series, vol. 41, Nov. 1979, p. 391-411). The paper provides a good introduction to the general problems of ephemerides, and the stated accuracy of +/- one minute of arc is extremely conservative, and for the current era +/- six seconds of arc is realistic. This ephemeris also calculates the 'First point of Ares', enabling star positions to be computed. I used this method to navigate my small yacht by sextant from Southampton UK to Pireaus Greece, with my worst landfall being one third of a nautical mile out. That was in pre-GPS days.
A more accurate methodology, but also much more compute intensive, is Pierre Bretagnon's VSOP82, subsequently developed and refined to VSOP87. The raw data tables which make the basis for the computations are out there on the web somewhere, I'm sure. When written into a program, it is spritely enough on a PC, but might tax all but top-end mobile devices.
A very good source of foundational information is the US Navy's Nautical Almanac, particularly in the 'Explanatory Supplement', a separate publication. Any year will do. Also, get a thorough understanding of the 'equation of time', as it occurs in just about every ephemeris calculation.
A couple of years ago I rewrote my original HP75C program to run on Android, and expanded it to cover not just the sun, moon, six navigational planets, fifty-eight navigational stars and Polaris, but included all ten thousand stars visible to the naked eye (given very good eyes and excellent viewing conditions  ). Even on an old Android phone it runs fast enough to be useful, although the virtual graphical sextant 'scope view is distinctly laggardly when scanning the sky.
