How to extract data from a table dynamically?

I have the following table

And I would like a formula that would produce the following result

enter the description of the image here

I would like to browse the table by going from left to right, from top to bottom and if there is a value in a cell, I would like to come back with the corresponding criteria from the top line. How would I do that?

magento2 – dynamically changes the layout according to the url setting

The standard layout of my categories is 2 columns to the left, so layered navigation is visible in my shop. What I want is to use the same categories to display content.

This is an example for my shop link:
products / chemicals.html
If I click on this link, my products are displayed in my list.phtml

This is an example for my link "cms":
products / chemicals.html? cms_id = 123
If I click on this link, my content "cms" is displayed in my list.phtml

What I want now is to display my content without the left sidebar.
By css, I can set the display of the sidebar: none, it works, but the page loads my products.

I would prefer to change the layout when I call my category page "cms".

An idea?


How to compare a cache allocation technology to a dynamically assigned watchdog from MIT for the prevention of side channel spectrum attack?

After research, I find it difficult to find a way to compare each solution. Is it correct to say that both solutions are software-based? Therefore, could I compare the overall performance of a computer with each software implementation?

network – Dynamically add a network adapter to Windows

I need to dynamically add network interfaces to a Windows computer.

Regarding its configuration, I know that I can configure an existing network interface card using the netsh cmdlet.

If I had to work manually, I could have used the hardware assistant application. Unfortunately, working manually is not a viable solution in my case

I tried to create a new entry in the registry tree [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E972-E325-11CE- BFC1-08002bE10318}] but it did not seem to work in my case

Any other suggestion on how this could be done is welcome

javascript – how to dynamically build an array of objects in js

I'm trying to create a reaction app that constantly updates the details of the order on the fly. I'm therefore trying to create a dynamic array of objects to contain these order details and display them as needed.

I'm not sure to build a dynamic array of objects.
control object to these accessories,

var order = [
‘id ‘: ‘ ‘,
‘ name’: ‘ ‘,
‘quantity ‘: ‘ ‘,
‘price ‘: ‘ ‘

How to build the command object in react? Is there an alternative to this approach?

domain name system – sssd dynamically updates the DNS

I'm trying to figure out how to get SSSD to dynamically update the DNS for different domains, map by map.

For example, if I have a server named that has two network interface cards.

I would like the first NIC to use DDNS to update the NIC1 DNS entries to reflect However, for Network Card 2, I want to try to register it in the DNS under the name

The files and are served by the same Kerberos domain (AD or IPA).

The problem I encounter is that the host name is determined by the system host name or by the ipa_hostname value in sssd.conf. Since these values ​​must be fully qualified, I can not simply add the DNS domain suffix to the host part to dynamically generate the FQDN.

I have seen people write nsupdate scripts, which I would like to avoid having to implement in an environment of nearly 1,000 servers.

My question is simply this: Is there a simple way, native to sssd, to accomplish the above?

api design – Are REST methods that safely return dynamically generated random data

Is a REST method that returns dynamically generated random data for each access considered safe?

According to RFC 2616 (that's me pointing out):

In particular, the convention has been established according to which the EEG and HEAD methods SHOULD NOT have the importance of taking any action other than recovery. These methods should be considered "safe". This allows the user agents to represent other methods, such as POST, PUT, and DELETE, in a special way, so that the user is informed that a potentially dangerous action is requested.

Naturally, it is not possible to make sure that the server does not generate side effects as a result of the execution of a GET request; In reality, some dynamic resources consider that a feature. The important distinction here is that the user has not asked for side effects and therefore can not be held responsible.

From what I understand from this, the method should be considered safe because the only action is to recover. The state of the server does not change with multiple calls (although the result may be different), since all the side effects generated would be the same (like logging of terminal access).

I am not sure if this is the case, because no real resource is used because the data is generated dynamically. I could also misunderstand the concepts of safe methods, idempotence and their relation with the REST APIs. Any information is very appreciated!

I have a dynamically generated page in a WordPress environment. This page uses a simple, no parameter shortcode, but the page is launched via another page and transmits a URL parameter. This parameter specifies the dataset that I have to display on the page. Works great, with a big but …..

Sharing on the page works. The link correctly shares the location and with the URL parameter, the correct information is displayed at the opening. BUT I want the image, the description and the name to be different from those of the default page.

After some work and the help of other people here on StackExchange, I managed to change the header with the mandatory meta fields of facebook and to confirm the existence of it .

First of all the title of the page:

    add_filter (& # 39; document_title_parts & # 39; ChangeTitleParts & # 39 ;, 10, 1);
function ChangeTitleParts ($ TitleParts)
if (isset ($ TitleParts[ 'title' ] ) && $ TitleParts[ 'title' ] == & # 39; Details & # 39;)
$ TitleParts[ 'title' ] = $ _GET[ 'Name' ];

return $ TitleParts;

Then change the meta-values ​​in the header:

    add_action (& # 39; wp_head & # 39 ;, & quot; add_custom_meta & # 39 ;, 10);
function add_custom_meta ()
$ slug = basename (get_permalink ());
if ($ slug == & # 39;)
$ Name = $ _GET[ 'Name' ];
$ Desc = $ _GET[ 'Desc' ];
$ Logo = $ _GET[ 'Logo' ];
<meta property = "og: title" content = "> "/>
<meta property = "og: description" content = "">
<meta property = "og: image" content = "">
<? PHP

The meta-properties of Facebook are as such:


The problem is that facebook refuses to display the title, description or associated image, even if the required meta values ​​are in the header. What am I doing wrong?
