Customize the default request options (camera to share) when you activate the camera in Firefox with code development

I have 2 cameras on my PC. When I try to activate the camera in Firefox, a permission request box with webcam options always opens. But I don't want to show the camera options in the dialog box. So, is there anything customizable to customize the warning box for Firefox by updating the JavaScript changes (I am a developer. Therefore, I want to fix it by updating the code for my web application)
Does anyone help me solve this problem?

reference request – Good book about the history of programming languages?

I would like to read a book about the history of programming languages, which places its development in the context of its times. In what context were concepts developed such as structured programming, object-oriented programming, etc.? I was introduced to the programming when OOP was well developed and, therefore, I don't really know what it was like to develop OOP for the first time. Similarly for structured, procedural programming, etc.

Is there a good book that starts with the first programmers who worked directly on the computer code, and goes through the different developments, showing how the developments were not trivial at the time (although from our current perspective they may seem natural and obvious) ?

reference request – Looking for a good book on the numb transcendental

I am looking for advanced boot text and friendlier friend text, especially in the advanced ones. One thing in particular that I am looking for is a geometric approach to the theory, since I could not find one, but anything related to the theory of transcendental numbers will be welcome.

Ah, also an algebrai geometry approach or a category theory approach will be very useful for my project.

PS: I'm sorry for English, it's not my main language.

WooCommerce: How to request the status drop-down box in the ADMIN New Order section

I am trying to require a handful of fields in the WooCommerce administration area within the Create New Order form. I have successfully resolved how to do this for all fields, except for the status drop-down menus. This is what I have so far (all this code works correctly):

// Requires certain fields in the creation of a NEW ORDER through Admin
add_filter (& # 39; woocommerce_admin_billing_fields & # 39 ;, & # 39; woocommerce_require_admin_billing_fields & # 39;);
woocommerce_require_admin_billing_fields ($ fields) {
$ fields (& # 39; first_name & # 39;) (& # 39; custom_attributes & # 39;) = array (& # 39; required & # 39; => & # 39; 1 & # 39;);
$ fields (& # 39; last_name & # 39;) (& # 39; custom_attributes & # 39;) = array (& # 39; required & # 39; => & # 39; 1 & # 39;);
$ fields (& # 39; address_1 & # 39;) (& # 39; custom_attributes & # 39;) = array (& # 39; required & # 39; => & # 39; 1 & # 39;);
$ fields (& # 39; city & # 39;) (& # 39; custom_attributes & # 39;) = array (& # 39; required & # 39; => & # 39; 1 & # 39;);
$ fields (& # 39; zip code & # 39;) (& # 39; custom_attributes & # 39;) = array (& # 39; required & # 39; => & # 39; 1 & # 39;);
$ fields (& # 39; country & # 39;) (& # 39; custom_attributes & # 39;) = array (& # 39; required & # 39; => & # 39; 1 & # 39;);
$ fields (& # 39; email & # 39;) (& # 39; custom_attributes & # 39;) = array (& # 39; required & # 39; => & # 39; 1 & # 39;);
$ fields (& # 39; phone & # 39;) (& # 39; custom_attributes & # 39;) = array (& # 39; required & # 39; => & # 39; 1 & # 39;);
return $ fields;
}
add_filter (& # 39; woocommerce_admin_shipping_fields & # 39 ;, & # 39; woocommerce_require_admin_shipping_fields & # 39;);
woocommerce_require_admin_shipping_fields ($ fields) {
$ fields (& # 39; address_1 & # 39;) (& # 39; custom_attributes & # 39;) = array (& # 39; required & # 39; => & # 39; 1 & # 39;);
$ fields (& # 39; city & # 39;) (& # 39; custom_attributes & # 39;) = array (& # 39; required & # 39; => & # 39; 1 & # 39;);
$ fields (& # 39; zip code & # 39;) (& # 39; custom_attributes & # 39;) = array (& # 39; required & # 39; => & # 39; 1 & # 39;);
$ fields (& # 39; country & # 39;) (& # 39; custom_attributes & # 39;) = array (& # 39; required & # 39; => & # 39; 1 & # 39;);
$ fields (& # 39; state & # 39;) (& # 39; custom_attributes & # 39;) = array (& # 39; required & # 39; => & # 39; 1 & # 39;);
return $ fields;
}
// Requires fields that are not included in woocommerce_admin loops
vic_require_admin_fields () function {
eco & # 39;& # 39 ;; // order notes (excerpt)
eco & # 39;& # 39 ;; // payment method
}
add_action (& # 39; woocommerce_admin_order_data_after_shipping_address & # 39 ;, & # 39; vic_require_admin_fields & # 39;);

I tried to demand it in a similar way to the rest (through a filter aimed at identifying "status", but this was in vain. Does it seem that the way the form is constructed is through a drop-down menu?) Tag is set to show: none, so I really can't do much with that.

I can see that when I select a selection without a state, the SELECT field becomes an INPUT field, so I think I cannot point it to add the required attribute:

enter the description of the image here

It's fine if I can't do this with a filter. I am thinking that you may need a JavaScript connected to the form validation button. I can't seem to find the identification of the real form to validate through JavaScript, although I will probably look for more tonight when I'm home.

Any ideas to help me find a solution will be greatly appreciated!

apache2 – Bad Request on my local machine

I have the problem that in my local machine when I try to access a url of my project that I have configured via host it always gives me this error:

Bad request
Your browser sent a request that this server could not understand.
Additionally, a 400 Bad Request error was encountered while trying to use an ErrorDocument to handle the request.

The issue is that because of the project specification I have subdomains and I have the host file modified of the type 127.0.1.1 www.0.1.1, when trying to enter through www.0.1.1 I get this error but when entering through the normal ip It suits me well.

I thought it could be because of the apache httpd configuration but I can't find the solution

Reference request: What is known about the absence of very regular srg graphics (n, k, 0.2)?

Only two very regular graphics with parameters $ lambda = 0 $ (no triangle) and $ mu = 2 $ (any two non-adjacent vertices
they have exactly two common neighbors), see the wikipedia page: the Clebsch chart and the Sims-Gewirtz chart.

I am looking for information on the possible existence of more of these graphics. For what values ​​of $ n $ Y $ k $ are known do not exist?
