I am making a Javascript program and on of the functions is to convert altitude/azimuth to right-ascension/declination given a time and latitude. My code can find the declination fairly accurately, I checked with Stellarium. I have been using this site to help me with the math.

My program gives me the wrong value for horizontal ascension which I plan on using to find right ascension (I already have a function to find local sidereal time which works). Here is my code for the equation
var ha = asin(-sin(az)*cos(alt) / cos(dec)) * (180 / Math.PI); this code is in Javascript but I defined custom sin/cos/asin functions that take degrees as input and return radians because that is the form my data is in.

The site I use also says that this equation should give the same result
var ha = acos((sin(alt) - sin(lat)*sin(dec)) / (cos(lat) * cos(dec))) * (180 / Math.PI);
but, the two equations give different results and neither are correct according to stellarium. I have checked that all the variables I am putting in are correct and I am almost certain I entered the equation correct. Here is the full code on github. I need help figuring out how to fix this problem.
--Note this can be run with node js with no libraries The result I get is { ra: [ 23, 57, 37.9 ], dec: [ -5, 24, 38.88 ] }
It should be getting { ra: [ 5, 36, 22.6 ], dec: [ -5, 24, 38.88 ] it does not have to be exact, I only really care about the first number of ra (right ascension). It is also formatted in HMS format. The datetime is hardcoded to Febuary 1st 2022 12:00:00 so that is what you should set stellarium to if you are testing this out.

Here is the relevant code

I wanted to make a dynamic table view where a button was clicked to reveal a Table Row however, I get an error when I try to change the text of the button.

I have a springboot project that we got going quickly by using the various appropriate spring-boot-starter jars to bring in the appropriate transitive dependencies that we needed. Now, as we get closer to production launch, we are adding code-quality and code-inspection tools to tighten up loose ends. Some of these are tagging the starter jars as problematic, but I am finding inconsistent advice as to how to handle the problem.

Spring.io documentation fails to weigh in on this. Starters are described here: Spring Starters, but it really just says they are used to "get going quickly" but does not indicate that they are intended for use in production. The starters are not listed in the 'production ready' features (which focuses on Actuator). The Packaging for Production makes no mention of starters. From Spring documentation alone, you are encougaged to use the starters (to get going quickly), but are not told to, or told not to, use them in production.

If the spring project adds either gradle-lint plugin, or uses maven-dependency-plugin, use of the starters flags problems. The starters include no code themselves, but they pull in useful transitive dependencies (by design), but that's contra-indicated by the lint plugins. Related incident here

From gradle-lint Generally, applications only use a subset of the libraries included in such families. The unnecessary dependencies included with the family both increase the footprint of the application itself. If the 'application' is actually itself a library, these unnecessary dependencies leak downstream to its users, increasing their footprint and potentially introducing breaking version conflict resolution problems.

Is the "right" answer to remove starter jars before going live? Should starters be used in production? I am sure there are plenty of projects that have gone to production with starters, and probably they have done so successfully. But it looks to me like the authorities differ on what to do, so looking to reconcile them.

I currently have a header with a bootstrap carousel under the header. I want to make it so the header sits on top of the carousel so that when I make the header transparent it shows the images of the carousel through my header. Any input on this would be greatly appreciated and I have provided the code below.

I have on my hand :

• an Airflow instance created using Google Composer in a VPC
• a postgres database on Scaleway protected by Nebula Mesh with a configurated RPN

My goal is to connect Airflow with the postgres Database.

My first thought was to create a NAT Gateway with Nebula mesh running on the router with associated certificates to use the ssl connection. But if I understand everything right, I can't install Nebula on the Google's CloudNAT/CloudRouter. I would need to create a NAT Proxy VM myself, which I guess isn't the simpliest idea.

Another idea was to "connect the VPC" to the Scaleway RPN using RPN VP allowing me to bypass Nebula. But I'm not sure how to do so, I tried creating a CloudVPN but something went wrong in the process and I didn't catch any pong.

Can anyone hint me on the right process to solve my problem ? What would be the easiest way to do it ? I'm not fluent yet with cloud platform and networking, so I'm kinda lost in the heavy documentation !

Thank's in advance

I'm trying to integrate jquery into my wordpress theme. I have integrated this code into my function.php but it doesn't work. Can anyone see the problem? Thanks.

Recently I added some kotlin activities and a library project to current java project. I can run project without any problem. clean - build - rebuild - run all are ok.

the problem appears when generating signed APK. I get below error:

Goodevening all.I am having trouble implementing my first bootstrap Nav bar. I have gotten it to succesfully work but my section that's right below it is overlaping the navbar (Im only able to see the navbar if i use a z-index of -1 but then the buttons in that section do not work). I have tried to change the heigh/width through css but am limited to how small I can make the section.

This is the problem i'm having: https://imgur.com/a/3CwLnK3

1st problem: You can see how the hero section goes over into the next area. Also how do i limit the margin on padding/margin on left and right of Hero section? I tried to adjust in css but it would not let me.

2nd problem: you can see how the img which is in the services section is not resizing itself to stay within the boxes (stars)
