## Thunderbird 52.1 -> Disable all junk-related // scanning features

This concerns Thunderbird 52.1.1. I have currently disabled or disabled all junk mail-related settings on the Security tab. Even so, I occasionally get the message that "Thunderbird thinks this is junk mail" and I have to say that this is not the case. Where is there a setting that I can disable once and for all?

## Features – How to create fake views on WordPress

I do not know how to code and I apologize for my bad English. So I found a code here to make \$ random = rand (700,999) a random view of my post views. which create a random view for my post, but the problem is that each time a user clicks on a post view, the view changes again and the metadata is not updated.

``````Function ktz_setPostViews (\$ postID) {
\$ count_key = & # 39; post_views_count & # 39 ;;
\$ count = get_post_meta (\$ postID, \$ count_key, true);
if (\$ count == & # 39;) {
\$ count = 1;
delete_post_meta (\$ postID, \$ count_key);
add_post_meta (\$ postID, \$ count_key, & # 39; 0 & # 39;);
}otherwise{
\$ count ++;
\$ count = rand (700,999);
update_post_meta (\$ postID, \$ count_key, \$ count);
}
return \$ count; / * so you can show it * /
``````

What I want is every time a user clicks on a post, the views do not add up to 700 – 999.

Please help me to create a wrong view for my website.

## DNS – domain hoster with reverse proxy features?

Hello dear web app user,

Sometimes I registered a domain with a (random) domain hoster and would like to write requests to that domain to another backend. For most providers, you can only redirect. That's not what I'm looking for.

In this example, a domain should be rewritten to send requests to a WIX site.

Do you know a good domain host who has such skills? The simpler, the better, d. H. I would prefer if such a rule could be set up for rewriting via a web frontend.

Thanks, Sebastian

## Features – Refactor create_function – WordPress Development Stack Exchange

You should be able to change create_function (& # 39; \$ a & # 39 ;, "return null;") in Anonymous Function (aka Closure):

From :

``````                add_theme_page (

\$ this-> args['page_cap'].
\$ this-> args['page_slug'], & # 39; & tab = dev_mode_default & # 39 ;,
create_function (& # 39; \$ a & # 39 ;, "return null;")
);
``````

On:

``````                                add_theme_page (

## Features – How do I create a new WP Admin color scheme?

I've followed this guide, but idk if it does not work for WP 5.0+ or ​​if I'm doing something wrong.

I've added this to my functions.php and the CSS file is a copy of the light scheme.

``````    function additional_admin_color_schemes () {
\$ theme_dir = get_template_directory_uri ();

wp_admin_css_color (& # 39; pro & # 39 ;, __ (& # 39; Pro & # 39;),
\$ theme_dir. & # 39; /wp-content/themes/astra-child/colors.min.css&#39 ;,
Array (# 3998DB # 3998DB # 3998DB # 3998DB)
);
}
add_action (& # 39; admin_init & # 39 ;, & # 39; additional_admin_color_schemes & # 39;);

## Equipment Recommendation – What Manual Features Does a SLR Film Camera Need for a Photography Course?

The Pentax K1000 is the classic student camera and would be perfect. My first was the similar Ricoh KR5, which was great. I did not use the Canon AE-1 or Nikon FM2, but based on the images I've googled, I can see that they have the standard manual exposure control and are okay too.

There are no different types of manual exposure mode. You can all choose what aperture and shutter speed you want, and that's exactly what your daughter will need for the class. With a digital camera, the ISO can also be selected from image to image. For a movie camera, select this when loading the movie and leave it until you switch to another movie.

Of course she will also need a lens. The default recommendation here is 50mm, as this provides a similar perspective to the human eye. If you buy the camera and lens separately, make sure you get a lens with the correct frame. If you need help finding a suitable lens, you can post it here with the body of your choice.

I would also suggest a camera bag and a tripod. It does not need anything expensive here, I would recommend a LowePro bag (she is great and stands behind her products … I have one that is 20 years old and is still in good condition). Something like the Lowepro Adventura SH 140 II should be a good size. A cheap tripod is handy. I did not use it, but the specifications of the Sunpak 6630LX are suitable for an introductory course.

## How do I add "remove_filter (# the_content # 39; wpautop # 39)"? minor topic features in WordPress?

I need to remove the "wpautop tag" from my WordPress site because too many paragraphs are added. I am new to WordPress. I can not edit child topics.

## Features – Allow custom roles to access specific pages (or subdirectories)

This seems common, but I can not find a solution. Try to avoid using a plugin as this will feel uncomplicated. I'd like to create three types of users, each of which can access specific pages on the sites (various sales pages) or grant access to an entire subdirectory or an entire group of pages. (ideally)

What I would like to do is say something like this:

``````// Create a custom user role

\$ result = add_role (& # 39; client & # 39 ;, __ (& # 39; vendor & # 39;),

Array (
& # 39; read & # 39; => true, // true allows this function
& # 39; # 39 & edit_posts; => false, // The user can not edit his own posts
& # 39; # 39 & edit_pages; => false, // user is not allowed to edit pages
& # 39; # 39 & edit_others_posts; => false, // The user can not edit other posts, not just his own
& # 39; # 39 & create_posts; => false, // user is not allowed to create new posts
& # 39; # 39 & manage_categories; => false, // Allows the user to manage post categories
& # 39; # 39 & publish_posts; => false, // Allows the user to publish, otherwise posts will remain in design mode
& # 39; # 39 & edit_themes; => false, // false denies this ability. The user can not edit your topic
& # 39; # 39 & install_plugins; => false, // user can not add new plugins
& # 39; # 39 & update_plugin; => false, // user can not update plugins
& # 39; # 39 & update_core; => false // user can not perform core updates
)
``````

to create the role, and then specify a number of additional pages that only they can access. (No restriction of other typical levels, editors, sub, admin, etc. required, as only the administrator is used.)

Right now, all I can see is the solution that forces people to a particular page that is a little less forgiving than I would prefer, but basically does what I want. Nevertheless, I assume that I can look in the SQL database for the ID of the user-defined user (I hope).

Restricting users to a specific front-end page

It would appear that combining these two elements would allow me to access a particular page by looking for a specific user role. The disadvantage, however, is that I have to look for the ID of possibly many pages.

How do I check if a user has a specific role?

WordPress page limitation

I know that there is also an option to test if a person can access a page and then reject it, but again more specific than what I'm looking for. I assume that there must be a way to assign \$ functions to a user so that you can list only a set of pages or posts that only this access has.

Many Thanks!

## Features – FullSimplify does not work well (answer required for a specific variable)

(new in Mathematica)

I try to simplify the Schwarz derivation of f w.r.t. u[10]). Here f is the prime number of the Weierstrass function (In[8]) with some restrictions ([9])

``````in the[8]: = f[u_] : = D[g[u]u]in the[9]: = f[u]^ 2 == 4 g[u]^ 3 - a * g[u] - b

out[9]= Derivative[1][g][u]^ 2 == -b - a g[u] + 4g[u]^ 3

in the[10]: = FullSimplify[F&#39;&#39;&#39;[F'''[f'''[f'''[u]/ f & # 39;[u] - 1.5 f & # 39; & # 39;[u]^ 2 / f & # 39;[u]^ 2]
``````

Output (for some reason Out[10] is of this form when copying)

``````(
!  ( * SuperscriptBox[(g),
TagBox[
RowBox[{"(", "4", ")"}].
Derivative].
MultilineFunction-> None])[u] (g ^ [Prime][Prime])[u] - 1.5
!  ( * SuperscriptBox[(g),
TagBox[
RowBox[{"(", "3", ")"}].
Derivative].
MultilineFunction-> None])[u]^ 2) / (g ^ [Prime][Prime])[u]^ 2
``````

The output is in prime numbers of g[u] and the expression is not simplified. Every help is appreciated. I would prefer if the answer were a function of g[u],

## Abstract algebra – Geometric and topological features of the real general linear group

I am interested in deducing the properties of the determinant on the real Euclidean space by topological and geometric means, without first constructing them $$det$$ by axiomatizing its properties.

First, we know it $$GL (n)$$ Deformation contracts $$O (n)$$ by polar decomposition. Since $$O (n)$$ is compact and $$O (n-1)$$ is a closed subgroup of $$O (n)$$We receive a fiber bundle

$$O (n-1) to O (n) to O (n) / O (n-1).$$

Since $$O (n) / O (n-1)$$ is homeomorphic too $$S ^ {n-1}$$we get an exact order

$$pi_1 (S ^ {n-1}) to pi_0 (O (n-1)) to pi_0 (O (n)) to pi_0 (S ^ {n-1})$$

and since $$S ^ n$$ is simply connected for $$n geq 2$$.

$$pi_0 (O (n-1)) cong pi_0 (O (n)).$$

Check the result on $$n = 1.2$$follows inductively that $$GL (n)$$ has exactly two path components.

Because the identity component of $$GL (n)$$ is a normal subgroup, the quotient giving a homomorphism to a group of order 2, i. $$phi: GL (n) to mathbb {Z} _2$$,

Since $$mathbb {Z} _2$$ is Abelian, $$phi$$ unique factors due to the Abelianization $$GL (n) ^ {ab}$$ as $$phi = bar { phi} circ pi$$ from where $$pi: GL (n) to GL (n) ^ {ab}$$ is the canonical projection and $$bar { phi}: GL (n) ^ {ab} to mathbb {Z} _2$$ is the card $$g [GL(n),GL(n)] mapsto phi (g)$$,

When I find out how to proceed, clearly $$pi$$ will turn out to be $$det$$, and $$GL (n) ^ {ab} cong mathbb {R} ^ { times}$$,

If I manage to prove the multi-linearity and anti-symmetry of $$pi$$ in the columns of the matrices in $$GL (n)$$I expect that I can derive the Leibniz formula and prove the uniqueness to a true constant.

How could I prove multilinearity and antisymmetry in this regard?
