Architecture – Hierarchical Vs. chronological schema for a tree depth of 1

If you want your messages in chronological order, you must save them in a chronological schema. If you want your messages to be in hierarchical order, you must save them in a hierarchical schema.

There is no situation in which you would choose between them. So it makes no sense to ask about the advantages of one over the other.

Custom Taxonomy – How to quickly fix duplicate term slugs in hierarchical taxonomies?

My problem is that in WordPress I imported a few hundred terms from a custom taxonomy from another system into five languages. I have found out that these terms have sometimes duplicated snails, and they are not allowed.

I could fix it by hand, but it would take too much time. So I'm trying to find the fastest way to programmatically:

  • Find the terms that have duplicated snails
  • fix it

Without finding duplicates, I think it would be easy to use get_terms to get all the terms and then circling them and updating them without parameters.> The error should be fixed automatically.> This happens when you create a page to edit Open terms and just click on the "Update" button: If it is a duplicated slug, it will be automatically repaired.

Okay, is there any other cleverer way? Maybe a special WordPress feature to find duplicate slugs or something …?

Generate Hierarchical Path

I have a classstructure Table:

create table classstructure (classstructureid number(8,0), classificationid varchar2(25), parent number(8,0));

insert into classstructure(classstructureid, classificationid, parent) values(1001, 'FLEET', null);
insert into classstructure(classstructureid, classificationid, parent) values(1002, 'LIGHTDUTYVEHICLE', 1001);
insert into classstructure(classstructureid, classificationid, parent) values(1004, 'MEDIUMDUTYVEHICLE', 1001);
insert into classstructure(classstructureid, classificationid, parent) values(1022, 'ACTIVETRANSPORTATION', null);
insert into classstructure(classstructureid, classificationid, parent) values(1023, 'FACILITYWALKWAY', 1022);
insert into classstructure(classstructureid, classificationid, parent) values(1024, 'TRAIL', 1022);
insert into classstructure(classstructureid, classificationid, parent) values(1085, 'SIDEWALK', 1022);
insert into classstructure(classstructureid, classificationid, parent) values(1091, 'SDWRAMP', 1085);

select * from classstructure;

---------------- ------------------------- ----------
            1001 FLEET                               
            1002 LIGHTDUTYVEHICLE                1001
            1004 MEDIUMDUTYVEHICLE               1001

            1022 ACTIVETRANSPORTATION                
            1023 FACILITYWALKWAY                 1022
            1024 TRAIL                           1022
            1085 SIDEWALK                        1022
            1091 SDWRAMP                         1085

I want to reduce the records to hierarchy paths:



How can I do that?

public key – Which hierarchical deterministic derivation path is used for FIDO authentication on a Ledger Nano S?

Which hierarchical deterministic derivation path is used for FIDO authentication on a Ledger Nano S? Does it always ask for a different key or is it always the same key?

If I connect to Google for 2FA, can it request proof of the desired keypath, or must it be a specific key?

I wonder how much privacy I lose when using a Ledger Nano S that is not exclusive to a particular 2FA account. For example, What happens if I use it for multiple Google Accounts or other companies or have cryptocurrency? Could Google find a Bitcoin balance if the same ledger is used for 2FA?

Entity system – handling dynamic hierarchical entities in ECS

Here's the analogy:
I have an organism made up of cells that continue to be composed of a mixture of attachments.

What I currently have is a kind of child / parent event chain to handle attaching and removing components (which could affect anything along the chain) that do not contain any ecs at all, they are functions in the entities.

Now I've already used event components (for mouse events on objects).
If the system is supposed to be pure, would I create an attach component when attaching components, etc.? Even then, how would I get all the necessary receivers to the system that consumes the component? Is it worthwhile to handle it instead of a functional chain? Is there a better way?

seo – Hierarchical vs flat sitemap

Your question is actually divided into a few categories, each of which has different considerations:

XML Sitemap
In your Sitemap, you can specify both the frequency of change and the priority ranking for the various pages. In this way, search engines can determine how important a page is on the site and how often it should be crawled for changes. Avoid listing duplicate content sites like / fashion / women / shoes and / fashion / shoes / women. In such cases, select a URL as the canonical URL that you want to send to search engines.

URL structure
By maintaining a minimum hierarchy in your URL structure for each page or for faceted search results, a search engine can index your website and display top-level category pages. (The search result of a department store can, for example, show the different departments.)

user experience
A menu with too much depth can lead to a bad user experience, as the user may be overwhelmed by the choices or simply tired of browsing through many navigation levels. A well-structured search interface with the most common categories as predefined filters will help you avoid an overly complex menu. Similarly, users can use breadcrumbs on the page to return to the top category or subcategory pages.

Look for products in Engjne Optimization
For each product on your site, consider adding schema microdata to your markup. That way, search engines can identify the individual products that are being offered for sale on your E-Comm site. See

Also, consider adding an RSS or XML feed and sending it to multiple sources to improve the reputation of your site.

seo – Hierarchical vs flat site map

I want to create a sitemap for my ecommerce site.

On the homepage there is a multi-level menu like this:

Enter image description here

The user can click on one of the following links in the start page:

  1. Fashion -> enter the fashion department
  2. Fashion> Mrs -> Enter the women's section in fashion
  3. Fashion> Women> Shoes -> enter shoe unit under women

There is also a page link Help and about us This usage can navigate from At home Page.

What is the better way to create a site map in terms of SEO?

Enter image description here

So users have two ways to navigate MrsSubdivision, either directly through At home Page or from to navigate Fashion and then too Mrs Page.

Website Design – Hierarchical list for selecting an item

The user tries to select an item to use in a form. So it could be like selecting interests in an app where you can select the more general case (eg, sport) or the more specific one (eg, baseball).

I have hierarchical data where:
* Exactly one node can be selected.
* Users can select nodes anywhere in the tree
* Leaf node Got to be selectable
* Parent nodes can be selectable. Selecting a parent node represents a selection of all its child leaf nodes.
* Selectable parent nodes are unusual.
* The depth of the data is deeper than can be displayed on the screen immediately.

I'm developing a UI to search this data. This data must be usable on both desktop and mobile web interfaces.

I'm thinking about modeling a UI based on what Apple does with hierarchical menus, like the following. The differences in my case are mainly that:
* The elements can have three states: Selectable node, Refineable node, and Nodes with both functions. How do I make this look clear?
* My design must work well on both the desktop and mobile devices. How do I design the refinement signifier in an unobtrusive way that is clearly visible on desktop views?
* My lists have a lot of heterogeneous content. This is rare in Apple menus, z. For example, the shutdown button in the second screenshot. How do I show heterogeneous content without looking disjoint?
iOS settings menu

Notice the blue line at the bottom that represents different content.
Shut down iOS screen

What I've been thinking about is similar to Apple's design. The next two screenshots show the top level of the hierarchy and …
Top hierarchical level

… the screen afterwards foods is selected.
Refinement of the hierarchy

I like the multi-screen approach to this design for my use case, so first and foremost, I'm looking for feedback on which icons / buttons to insert and how content should be cut out. I'm particularly interested in web examples and high fidelity mocking examples, but I'm also open to low fidelity feedback.

The one structural thing that I think could be changed is the combination case in which a parent node can also be selected. Conceptually I presented it here:
Alternative design to the combination housing

I would like to point out that the rows are less crowded and more homogeneous. But I'm not sure how to do it exactly Current level Selection mechanism. How can I clearly indicate that the current level can be selected? How can I indicate the situation in which the current level is located? tilt to be selected?

Tagging – How do I clean up hierarchical tags when I add new layers in Digikam?

I suspect you are incapable of doing so because it would nullify the point of nesting.

You can create the same tag a second time out of this hierarchy, but at the point of


is that ant and cat are both animals, but not all animal is a mammal and or cat,

Therefore, if you are looking for the day animalHere you will find all animals. If you are looking for mammalYou will only find it mammals – and so on.

If, on the other hand, you had a housing search:


then there is no possibility that a picture is just tagged cat is found in the search animal,

Theoretically, one could have a routine that does the hierarchy thing automatically while the image contains only the tag catYour program puts it in animals and so on. I am not sure if DigiKam (or any other program) can do that, and it probably would not be the best idea because of the possibility that tags are not unique (eg. cat could also refer to machines from Caterpillar Inc.).

Tagging – Clean up hierarchical tags as you add new layers

I often find myself restructuring and refining my hierarchical tags Digikam,
Suppose an image is assigned day 2 which resides downstairs day 1:

day 1
Day 2 (image assigned)

If I decide now that I want to have Day 3 below day 2 and add Day 3 the image is then assigned to the image, day 2 and Day 3,

day 1
Day 2 (image assigned)
Day 3 (image assigned)

Is it possible to clean up the top-level tags and remove all tags above the bottom-level tag in the hierarchy from the image?
