ephemeris | Pure javascript implementation of ephemeris calculations | Game Engine library

So I am trying to get average lengths of the four seasons in the 21st century using PowerShell as a self-imposed programming challenge, my idea is to convert from string to array of pscustomobject, then for loop through the array using index, in each iteration, add year to the dates with the same index and convert the dates to [datetime] and add to another array, then loop through the second array using index and get season length using new-timespan and add to a third array, and measure-object third array, forgive me if this may sound confusing in English but it really is very simple in code.

Now I get the dates of equinoxes and solstices from here:Solstices and Equinoxes: 2001 to 2100

Using Notepad++ to format the dates I got this:

I have five files that I want to loop through so I can get all of the density dens values at the end. The code is the same except where I have i. The issue I'm having is that when I do print(dens) outside of the loop I am only getting the values from the last file (the fifth one). How do I fix the code to have all of the values from all of the files? I'm thinking I need to change dens.append at the end of the code but I'm not sure how. Just for reference this code is to interpolation between latitudes/longitudes to get density values.

I cannot resolve why I am getting a different azimuth/altitude for a comet calculation between PyEphem and Skyfield, yet the right ascension and declination match.

Code example:

As per the skyfield documentation online, I am able to calculate whether a given time of day is day or night.

I am developing a react native app with several screens. It has a screen that loads react native map. It's working perfectly on debug when I run react-native run-android. But when I create the signed apk and install it on a device other screens work fine, but when I navigate to the screen with map, the app crashes. This happened only with apk. So, I can't find a reason as well. This is how I implemented map.

I have a question about bitwise OR | operator from c to rust.

I have this lot of define to convert from c to rust, and i’m not sure of the flag SEFLG_ASTROMETRIC.

I've built a link with my c library and the call of a specific function gives me a non-helpful error message (probably because i'm using unsafe {} decorator).

The message is:

./build.sh: line 7: 44630 Bus error: 10 cargo run --example ferris-astro-example

and the line 7 is
