QUESTION
Hey guys I am having trouble creating a pattern that is called the invisible dance of the planets. This pattern is done by drawing a line in between two different planets and is shown by this animation. The issue I'm having is with the for loop of drawing the lines, I got all the positions of the planets done depending on their number of years to rotate. Another factor to include is the change in color when a new year is cycled. The issue I'm having is the final image of the svg file. My Result Expected Result

QUESTION
I want to make a command that gives a role from the array when a member types its name. For example, they type r!register Myth and then it gives them the "Myth" role.
ANSWER
Answered 2021-Mar-26 at 13:55You can check if the role name provided by the user is in the list first, then you can use the .find() method to check if the role exists on the server. If it exists, you can add it to the user.
The following code should work:
QUESTION
I have this issue on my bot command. It doesn't remove any other specified roles other than the first defined one.
...ANSWER
Answered 2021-Mar-26 at 08:24Your callback function for find() is incorrect, and actually find() returns the first found element in an array. You could use .filter() to get a collection of elements instead and use the .includes() method to check if the role name is in the list provided.

QUESTION
We are trying to compile this by following instructions in the readme. I must say that we are not specialists with C at all, we are students of a web development bootcamp and trying to do our last project.
It's a command line tool to calculate ephemerides of multiple celestial bodies, and as you can read in the setup in the readme file, it need to download certain data from the internet, and then compile.
All is done through the setup.sh script.
So, we have tried:
- In Windows 10 ubuntu WSL terminal
If we type $./setup or $./prettymake, after download the data, gives the error:
ANSWER
Answered 2021-Feb-28 at 13:52A comment from the OP invites me to answer; here it is.
The prettymake script creates a named fifo in order to receive the messages produced by make on its standard error.
A background process (cat) consumes the data from this fifo and sends them to a sed command (see right after) in order to transform these data before writing to standard output.
(note that cat is useless here since sed could have directly read from the named fifo thanks to <)
However, the two sed commands as shown in the question don't do anything since they just capture each line of text (\(.*\)) and repeat them unchanged (\1), thus they could have been omitted.
In this case, the script could just contain make $@ 2>&1, it would have produced the same effect.
On a system where creating the named fifo is problematic (old version of WSL apparently), this change in the script should produce the same effect as expected.
Looking at the link provided in the question, we can see that the original prettymake script actually contains transformations in the sed commands in order to display standard output and standard error of the make command with different colours.
QUESTION
I am trying to obtain an ortographic projection of the celestial sphere, with equatorial coordinates, as seen from a certain latitude, as in the following picture:
(Grid obtained from Skychart/Cartes du ciel)
This image is a print of Skychart/Cartes du ciel, showing the equatorial grid for an observer at 23°S latitude. I want to be able to reproduce the exact same image in Python (apart from the dark blue background). My first attempt was to use CartoPy, setting the central latitude as -23, as follows:
...ANSWER
Answered 2021-Feb-24 at 07:43First of all, your first image is Azimuthal Equidistant Projection. So that, it is quite different from your second plot (Orthographic projection). To get the plot (first image) like that using Cartopy requires some steps that are interesting to follow. Here is the code with comments that produces the output plot that I consider a good result.

Answered 2021-Feb-15 at 02:53It turns out that raycaster-intersected-cleared event from parent element is fired but it does not mean that it is not intersected anymore. To confirm if it has been still intersected I have to check if getIntersection result is NULL.

I'm trying to load a page with a canvas and then save it as an image.
For example, this page. On Chrome, I can right click the canvas with a circle on the upper right side of the page and click save image. I want to do this exact same thing but through NodeJS and Puppeteer. Is this possible?

I want to display a list of pictures of different celestial objects I took (nebula, galaxies, etc...).
