unity – How do I get the main camera from a root object?

In my scene, all objects are children of game object named “SceneRoot”.

The main camera is a child somewhere in this hierarchy, for example at


I need to attach a raw image to it using code.

To do that, I first need to find this camera.

I have tried

GameObject go = SceneRoot.GetComponentsInChildren<Camera>();

But that throws the error

Type "UnityEngine.Camera()" can't be converted to "UnityEngine.Camera".

How could I get the camera object in order to attach a raw image to it?

Thank you!

Cannot access WordPress Multisite Main Dashboard

We have a number of sites that use WordPress Multsite and over the last couple of months we have noticed that we now cannot access the main WPMS Dashboard any longer where the plugins are added, users are updated or themes are enabled.

Here’s what we have tried.

  • backed up htaccess and WP config files.
  • renamed htaccess by adding a dash at the end of the file name (.htaccess-)
  • setting the WPMS settings to false

/* Multisite */
define( ‘WP_ALLOW_MULTISITE’, false );
define(‘MULTISITE’, false);

  • Updated all the plugins
  • Updated Core
  • Reversed all the work done
  • Still the same result

I have Googled and read through all the options related to my search but none of the options I have found to have worked

Any thoughts? Thanks

Why my nginx conf file redirects subdomains to main domain?

I have removed all files from /etc/nginx/sites-enabled/ directory.

I have also removed all files from /etc/nginx/sites-available/ directory.

I only have one file in /etc/nginx/conf.d/ called my-domain-name.com.conf and it contains:

server {
    listen 80;
    server_name my-domain-name.com www.my-domain-name.com;
    return 301 https://$server_name$request_uri;

server {
    listen 443 ssl;
    server_name my-domain-name.com www.my-domain-name.com;

    ssl_certificate /etc/letsencrypt/live/my-domain-name.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/my-domain-name.com/privkey.pem;

    include /etc/letsencrypt/options-ssl-nginx.conf;

    location / {
        proxy_pass http://localhost:4000;

I proxy traffic to a docker container that listens on port 4000.

It works great for my-domain-name.com and www.my-domain-name.com.

However, it also redirects ALL of my subdomains that have been defined in DNS.

This is not the intended behavior. I only want this file to serve these two domains, not more.

What is wrong here?

windows 10 – Main Monitor of my Laptop does not work anymore

I encountered a very strange problem:

I have a Laptop (Acer Aspire 5 windows 10) and a second screen connected via HTML. Everything worked perfectly until yesterday:

All of the sudden only my second screen works and my primary screen is all black. Nothing changed when i changed the settings using windows+p.

Now to the strange part: When I pluged out the second screen and restarted the laptop everything seemed normal, but today I encountered the very same issue again. Without plugging in the second screen my primary sreen just went black.
When I pluged in the second screen it works on this screen.

When I restart the Laptop without the second screen it works on the laptop but when I plug in the second screen it is the same problem again.

In the device manager both monitors are shown as working properly.

I already updated the graphic card drivers. But aside from this I could not find any tip online about what to do now.

I don’t think there is a losse contact from main screen to main board since I could work for hours this morning without any issues.

I hope someone can help me,


blockchain fork – Choosing main chain based on difficulty

If a node observes a fork in the bitcoin chain, then the node will choose the chain that has the highest difficulty (sum of difficulty in each block of the chain).

But the difficulty changes only once every 2016 blocks. So, if a fork occurs somewhere in between, then the difficulty is the same for both the side chains right? How does the node pick the main chain then? Just randomly?
