I'm trying to search over an index that includes constellation code names, and the code name for the Andromeda constellation is And.

Unfortunately, if I search using And, all results are returned. This is the only one that doesn't work, across dozens of constellation code names, and I assume it's because it's interpreted as the logical operator AND.

(constellation:(And)) returns my entire result set, regardless of the value of constellation.

Is there a way to fix this without doing tricks like indexing with an underscore in front?

Thanks!

I am connecting to a mongodb collection named 'Users' which has the _id field. I am attempting to find and update an existing document in the database using mongodb findOneAndUpdate() method. To begin with i pass in the id as an argument to my function which works fine. The document does indeed update using the $set method but still outputs the resolve when it should catch the reject when there is no existing document.

How do i catch the error with a promise. I think the issue here is that i am not getting any response back from the mongodb api unless i pass it to a variable. However still knowing this, how do i catch the error when there is no existing document that does not match the query?

Heres my code:

I have different look and feel (not a theme - but a completely different look and feel) for my ASP.NET MVC project. My customer can select which look and feel they want and I will publish it.

So far, I split each look and feel to different projects and they share the same code. Now, the number of look and feel has increased dramatically. There are over 30 different "look and feel" option to choose from. Yes, I have 30 different projects, all codes are exactly the same (including the javascript), except the View (cshtml) and the css files.

Is there an easy way to only publish a specific view? For example, I have the following view options:

• Modern
• Contemporary
• Classic
• Unique
• Andromeda

If my customer asked me that they want to use Modern "look and feel", then I will open the "Modern project" and publish it to their Azure server.

Any idea on how to use only 1 project and use something like "conditional publish"?

Thanks...

I am trying to create a custom WCS to transform pixel coordinates of an image into world coordinates.

Given an image with stars, I already have identified 2 stars, so I can match pixels (x,y) to (RA,DEC) for two points in the image.

What I would like now, is to create a custom WCS with the proper transformation matrix, so when I give any pixel coordinate it will return the corresponding RA and DEC.

I known astrometry.net does it, and writes a fits header with the appropriate transformation matrix.

My question is, how can I get to this transformation matrix and create my custom WCS object?

Thanks.

EDIT: This is the code I'm trying:

I am trying to create a simulation of 3D distribution of galaxies.

The galaxies are points.

question1.htm uses galaxydata1.txt to calculate and load the galaxy positions:

So I have a problem that goes as follows:

Xzqthpl is an alien living on the inconspicuous Kepler-1229b planet, a mere 870 or so light years away from Earth. Whether to see C-beams outside Tannhäuser Gate or just visiting Sirius for a good suntan, Xzqthpl enjoys going on weekend trips to different faraway stars and galaxies. However, because the universe is expanding, some of those faraway places are going to move further and further away from Kepler-1129b as time progresses. As a result, at some point in the distant future even relatively nearby galaxies like Andromeda will be too far away from Kepler-1229b for Xzqthpl to be able to do a weekend trip there because the journey back and forth would take too much time. There is a list of "n" places of interest to potentially visit. For each place, Xzqthpl has assigned a value "v_i" measuring how interested Xzqthpl is in the place, and a value "t_i" indicating the number of weeks from now after which the place will be too far away to visit.

Now Xzqthpl would like to plan its weekend trips in the following way:

1. No place is visited more than once.
2. At most one place is visited each week.
3. Place "i" is not visited after week "t_i"
4. The sum of values "v_i" for the visited places is maximized

Design an efficient (polynomial in "n" and independent of the v_i’s and t_i’s assuming the unit cost model) algorithm to solve Xzqthpl’s travel planning problem.

Currently I don't really know where to start. This feels like a weird variant of the "Weighted Interval Scheduling" algorithm (though I am not sure). Could someone give me some hints on where to start?

My inital thought is to sort the list by "t_i" in ascending order... but I am not really sure of what to do past that point (and my idea might even be wrong).

Thanks!

I am trying to set up a Flask server which supports both regular API calls and WebSocket connections. All traffic is routed through an NGINX load balancer, an NGINX reverse proxy and then thought uWSGI running in Emperor mode with 2 vassals - 1 for regular API and the second one for WebSockets. All connections to the first one seem to work as expected. When connecting to the second one, some connections go through, returning a 200 (both with polling and websockets), but mostly they return a 400.

NGINX reverse proxy config:

When I tried to run npm run dev in my nuxt project, my console returned this message:

Anyone able to explain what I'm doing wrong with my use of asynchronous functions in Javascript?

Basically, I must use an asynchronous in my Node.js code to grab an open port for me to use. There is a local variable that is being set outside of the asynchronous call that I can access/use just fine until I await for the asynchronous function to return. After that, the local variable is undefined.
