QUESTION
I'm using healpy to plot the locations of galaxies on the sky from a list of RAs and Decs. So far, I think I've been able to correctly plot the galaxies, but I'd like to improve the finished product. Is there any way to bin the number of galaxies that appear in each healpy tile, rather than just coloring being based on whether there is or isn't a catalog member in the tile?
Here I show the image that I'm currently making —
right now it's only really useful for telling you where the Milky Way isn't. Here's the code I'm using.
...ANSWER
Answered 2020-Sep-28 at 20:47You could use numpy.bincount to create an array of the number of galaxies per pixels and then create a map of that.

I'm using D3 to zoom onto an image on click and on Mousewheel. Everything is working fine but the first zoom glitches a lot.
Here is the demo of the app.
This is how I'm zooming towards the objects:
...ANSWER
Answered 2020-Oct-06 at 21:05The issue seems caused by a very expensive CSS repaint cycle. I tested this in Firefox by going to Performance in the DEV tools and starting a recording, then zooming for the first time.
I saw the fps drop enormously, and that the repaint took as much as 250ms. Normally, that is 10-50ms.
I have some pointers:
- Why do you have two images behind each other? Big images are definitely the reason why repainting takes this long, and your image is 8000x4000 pixels! Start by removing the image that we're not even seeing;
- Try adding an initial value of
transform="translate(0, 0) scale(1)"to.scale-holder. I have a feeling that adding this the first time is what forces the entire screen to be repainted. Maybe changing an existing scale value is an easier mathematical operation than applying a scale value to something that was not scaled before; - If that doesn't help, compress the image to at most 1600 or even 1080 pixels wide. Us mortals should not even be able to see the difference.
QUESTION
I am trying to pass an image as an asset property type to some other component (so that either a #selector or a url(url) can be passed) but it seems to take in the entire html component, instead of just the url.
...ANSWER
Answered 2018-Mar-27 at 13:59Please correct me if i'm wrong, but i think it's not in the material schema.
I think the devil's in the component.js, which not only seems to allow you to assign a value to any given property, but also has the constructor for any component, and parses the schema.
That being said, the material does not need a src in the schema, as it seems to be a part of every component. Furthermore there are multiple parsers like the assetParse, or src-loader, checking whether an attribute is a html element, or even a video / image asset.
QUESTION
I'm using backbone to manage my routing. I need to implement multi-language on my website as following :
- in french : www.example.com
- in english : www.example.com/en
Moreover I have an additional root on my url on production, so it gives www.example.com/dev or www.example.com/dev/en
The root is provided through my web server (node). It's retrieved through the <%- prefix %> variable in the example below.
It works well on localhost, but as soon as I pass on my server with a url with the additional root, the pages are not found. I'm looking for a generic solution to manage both situations (with or without root).

QUESTION
Given a 2D grid skyMap composed of '1's (clouds) and '0's (clear sky), count the number of clouds.
A cloud is surrounded by clear sky, and is formed by connecting adjacent clouds horizontally or vertically. You can assume that all four edges of the skyMap are surrounded by clear sky.
Example
...ANSWER
Answered 2017-May-21 at 05:35This can be solved by computing connected components directly on the sky map matrix. We can use the data structure of Disjoint-set.
In this example, the implementation of Disjoint-set (UnionFind) is taken from here:

Install Skymap
You can use Skymap like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the Skymap component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
