## Decades of old website in the finance category

This site is in the finance category and has been online for over a decade. I've linked an Adsense screenshot with the revenue since 2008 and an Analytics screenshot since 2015 (at the earliest). The RPM for this site is very high at \$ 31.49. It has earned \$ 1,147.68 since it went online.

Do not want any updates or maintenance anymore.

How is it monetized?

No

How long does it take to run this website?
Zero, unless you want to add new content.

What are the challenges in running this website?
None, just a simple Adsense site.

## Time Complexity – Can an optimal global trees classification tree be created for each category?

Suppose we have a series of objects, each of which belongs to one of the disjoint categories $$c_1, …, c_n$$, Suppose that for each category $$c_i$$ there is a corresponding amount $$T_i$$ This contains all the optimal binary classification trees that divide the objects only by whether they belong to them $$c_i$$ or not. Optimal is defined as the least sum of distances from the root to the leaf nodes.

Question: Can this adjust $$T_1, …, T_n$$ be used effectively to create a single global binary classification tree that classifies objects for each category and is also optimal?

## mysql – Returns an ID specifying data that does NOT have the same category as the given id

I have 3 tables: video, video_category and video_category_join.

A video can have multiple video_category and a video_category can be associated with multiple videos: hence the video_category_join table

TABLE: Video

`| video_id | title | description | Duration |`
`| --------------------------------------------`
`| 12 | hello | ... | 190 |`
`| 24 | hello | ... | 190 |`
`| 78 | hello | ... | 190 |`
`| 34 | hello | ... | 190 |`
`| 91 | hello | ... | 190 |`
`| 88 | hello | ... | 190 |`

TABLE: video_category

`| video_category_id | name |`
`| ------------------------------`
`| 4 | Music |`
`| 8 | tv |`
`| 5 | black |`
`| 2 | politically |`
`| 1 | Movie |`
`| 6 | others |`

TABLE: video_category_join

`| video_id | video_category_id |`
`| ------------------------------`
`| 24 | 4 |`
`| 24 | 5 |`
`| 88 | 1 |`
`| 91 | 6 |`
`| 91 | 5 |`
`| 78 | 4 |`

Accepted `video_id`I want to select random videos that do NOT have the same category as the one specified `video_id`,

So for example, if the `video_id` At 24, the result set should return videos that do not match the same category as `video_id` 24. In this case, the only videos do not have the same category as `video_id` 24 are: `video_id` 88 and `video_id` 91st

This is a query that I thought might work, but if that is true `video_id` has no categories there is nothing back.

``````SELECT DISTINCT v.video_id, v.title, v.duration, 2 AS preferred
FROM video_category_join vc
JOIN video_category_join vc2 ON vc2.video_category_id <> vc.video_category_id AND vc2.video_id <> vc.video_id
JOIN video v ON v.video_id = vc2.video_id
WO vc.video_id = 5
ORDER BY EDGE ()
LIMIT 20
``````

I upgraded Magento through Megento Connect Manager from 1.9.2.0 to 1.9.4.2.
The upgrade process was successful and all loaded files except the category menu from the homepage. The catalog menu from the homepage is missing. I have a mega-menu module and tried to disable it but no luck. How can I restore the menu?
Connect Manager can log in after the upgrade. The sign-in page will refresh after logging in and return the following URL
Before I could log in by switching from https to http, but that did not work after the upgrade

Yes, it's

## Plugins – How do I display pagination for posts grouped by category?

I have a blog page where I list all categories as tabs. When I click on a tab (category), I take a picture of the API call example `http: // my_domian / abc / wp-json / wp / v2 / posts? categories = 35` Where 35 is the category ID. However, this always gets 10 newest posts and there is no scrolling to navigate to the next posts.

How can I implement paging in it? I miss something in the settings.

P.S: I have set a static page as the start page and have NOT set the posts page for the site.

## wordpress.org – View the post of the current parent category and display the subcategory contribution on the right

I have a category menu if category.php on the left shows only the contribution of the current parent category and the right one shows the contribution of the child category.

If I have two categories. A and B. A is the parent of B b is a child.

In the left side you want to display the entire contribution of Nur A, in the right side you want to display the contribution of Nur A only.

Both actions should be performed with the same template.

## magento2.3 – To display the total number of categories for a category in Magento Admin on the category page?

I want to show the total number of categories for this category below Add subcategory (Before showing / hiding all links) on the left side.

The total number of categories should also consider subcategories.
e.g. when I'm on Standard category (root category) then it should cover What's new? to Fitness Membership but not gear (since these are not children) in arithmetic.

For category counting, I use the below function, which works fine at the moment, but I do not know how to use this dynamic text under "Add subcategory".

``````\$ childrenCategories = \$ this-> getChildCategories (\$ category);
``````

Here `\$ category` would be an object.

## permalinks – Woocommerce – I'd like to have urban development sites for my product, state / city / product category / product

I am Amit and I'm not a professional website developer. I make my own E-commerce website for cake delivery With OceanWP Theme & Elementor in the WordPress,

My problem is what I want city-related pages for my product, where the customer is asked to click on the icon State Your choice (every state side has its cities), followed by another click on city Their choice (each city has a product category) and then they are asked to choose the one product category they want and finally click on the product You want to.

I need four loops in the slug > State / City / Product Category / Product

Please guide me step by step how to do it.

## haskell – Can two empty sets be isomorphic in category theory?

I am a Haskell beginner and would like to create a function to see if there is an isomorphism between two lists. I think if they have the same length> 0, the answer is yes.

But what about empty sets? Can there be an isomorphism between empty sets?

Many Thanks.

## Categories – Create isotope filter groups with category terms

Sorry for the big question. I am a bit lost and would like to provide all the data that is possible for understanding the problem. There are two ways to reach the goal. First, make the markup with a Walker, and then create the markup by iterating an array. The main question is how to build it with a stroller. Although I make my attempt to build it with an array available to ask if it is a good practice.

I have this category term structure:

``````Term-1 Level-1
Term 2 Level 2
Term 3 Level 2
Term 3 Level 2
Term-4-Level-2
Term-5 level 1
Term-6 Level 2
Term-7 level-2
Term-8-Level-2
``````

Trying to create this markup from category terms:

``````

``````

The question is: is it possible to build it with the Walker class? I tried unsuccessfully to extend Walker and Walker_Category as follows:

``````Class Isotope_Walker extends  Walker {

public \$ tree_type = & # 39; category & # 39 ;;

public \$ db_fields = array (& # 39; parent & # 39; => & # 39; parent & # 39; id & # 39; => & # 39; term_id & # 39;);

Function start_lvl (& \$ output, \$ depth = 0, \$ args =[]) {
\$ output. = " n n ";
}

Function end_lvl (& \$ output, \$ depth = 0, \$ args =[]) {
\$ output. = " n ";
}

Function start_el (& \$ output, \$ category, \$ depth = 0, \$ args = [], \$ id = 0) {
\$ output. = & # 39;& # 39 ;;
}

}
``````

On the other hand, I know that I can create an array of terms for iterating the array in the following ways:

``````public function filters ()
{
\$ terms = get_terms (array ()
& # 39; taxonomy & # 39; => & # 39; category & # 39 ;,
& # 39; # 39 & hide_empty; => false,
));

foreach (\$ terms as \$ term) {
if (\$ term-> parent === 0 && \$ term-> slug! = & # 39; no-category & # 39;) {
\$ Parents[] = [
'id' => \$term->term_id,
'name' => \$term->name,
'slug' => \$term->slug,
];
}
}

foreach (\$ parent as \$ parent) {
\$ parent_id = \$ parent['id'];
\$ {& # 39; parent_childs _ & # 39 ;. \$ parent_id}['parent_' . \$parent_id] = \$ parent;
foreach (\$ terms as \$ term) {
if (\$ term-> parent === \$ parent_id) {
\$ {& # 39; childs_of_ & # 39 ;. \$ parent_id}[] = [
'id' => \$term->term_id,
'name' => \$term->name,
'slug' => \$term->slug,
];
}

if (isset (\$ {# childs_of_ #. \$ parent_id})) {
\$ {& # 39; parent_childs _ & # 39 ;. \$ parent_id}['childs_' . \$parent_id] = \$ {# Childs_of_ #. \$ parent_id};
}
}

\$ output['parent_childs_' . \$parent_id] = \$ {# Parent_childs _ #. \$ parent_id};

}

return \$ output;
}
``````

This results in:

``````Array (size = 3)
& # 39; # 39 & parent_childs_3; =>
Array (size = 2)
& # 39; # 39 & padre_3; =>
Array (size = 3)
& # 39; id & # 39; => int 3
& # 39; # 39 & nombre; => String & # 39; s kindes visuales & # 39; (Length = 14)
& # 39; slug & # 39; => string & artes-visuales & # 39; (length = 14)
& # 39; # 39 & childs_3; =>
Array (size = 6)
0 =>
Array (size = 3)
& # 39; id & # 39; => int 4
& # 39; name & # 39; => string & # 39; Escultura & # 39; (Length = 9)
& # 39; slug & # 39; => string & escultura & # 39; (Length = 9)
1 =>
Array (size = 3)
& # 39; id & # 39; => int 4
& # 39; name & # 39; => string & # 39; Escultura & # 39; (Length = 9)
& # 39; slug & # 39; => string & escultura & # 39; (Length = 9)
2 =>
Array (size = 3)
& # 39; id & # 39; => int 4
& # 39; name & # 39; => string & # 39; Escultura & # 39; (Length = 9)
& # 39; slug & # 39; => string & escultura & # 39; (Length = 9)
``````

So I can iterate and create the markup without a walker. Regarding this method, I would like to ask if it is a good exercise or if it is better to walk on the sidewalk.

Many Thanks!
