## splistitem – Date of when a Field was populated

Is it possible to get the date of when a choice field was populated? I’m asking because we have a SharePoint list which is automatically populated by an automation and the entries are later reviewed by one of our team members. Whoever is reviewing the entry add his name to the entry through a choice field, and I’d like to get the date when the ‘Reviewed By’ field is populated. I thought about using a calculated column but I’m not sure what formula would get the results I’m looking for.

## node.js – How to apply server side datatable regex ( search ) ( filter ) using node js on different columns of two or more combined (populated )collections

i am getting data form two collections of mongodb using nodejs..one is student collection and other is books…in this project i am assuming that this is one to many relation (one student can read multiple books but each book will be read by only one student)..this could be a many to many relation but i m working with the situation (one student can read multiple books at a time but each book will be read by only one student at a time)..Now by using populate function in ( node js ) i am getting all the columns data of a books collection and student collection using Book model because i used the reference of student model in books but when i apply datatable server side regex search on all columns it only filters the column of books collection and not working for the columns belongs to Student collection.

## 7 – Content statistics: The “Most Recent” view is not populated

I have views in my Drupal 7 site that show the last 4 viewed objects. rather, it’s supposed to do so. Instead it shows 4 objects views almost 2 years ago, coinciding when we had an ISP migration.

I have built a very basic view to show me just the titles and the most-recent-view of the objecs, and I can see that the Content Statistics: Most Recent View field is null for nearly everything the past two years. (This is impacting other views as well, such as my “Ten Most Viewed” which has also remained stagnant.)

Has anyone encountered this in their Drupal 7 sites and found how to turn back on this information gathering?

## blocks – Adding section components with populated fields to a Layout Builder enabled node

I’m working on migrating content from fieldable panels panes in D7 to Layout Builder in D8. So far, I’ve managed to extract the content I need from my D7 database, but I’ve been unable to add that content to layout builder section components. Backing up a bit, I’m currently trying to just add some inline blocks with sample content to a layout builder section in an attempt to determine how to populate the fields, as follows:

``````    /*
Add an inline block of 'basic' type to a section
'basic' blocks only have a field called "body" of type "Text (formatted, long, with summary)"
*/
\$section = new Section('two_column');

\$testcomponent = new SectionComponent(\$this->uuid->generate(), 'first', (
'id' => 'inline_block:basic',
'label' => 'Test component label',
'label_display' => 'visible',
'body',(
'value'=>'Test',
'format'=>'limited_html_text',
)
));
\$section->appendComponent(\$testcomponent);

``````

After I run my migration, I end up with a node with a inline block of “basic” type in the “first” region, as expected, but it’s empty aside from the label. Could someone advise me on how to set field values for section components?

## nfs – Read-only file system that is populated on demand

Basically, I have a file system that both NFS and ssh can access. I need a copy of it on my local one. However, I only want to retrieve the files that I need (basically cache if necessary). Since I'm going to use this as a read-only fs, the cache is a permanent copy (even the remote doesn't change). Is there an application that does this right away or should I write my own FUSE implementation for it? The problem is that the FUSE implementation would be for Mac (although I have a Linux container that can do that).

## jquery – Few items in the SharePoint list are not automatically populated in the search bar

I am using a SharePoint 2013 website with one of the pages containing a search bar (using the "auto complete" feature). The values ​​from the SharePoint list must be filled in as soon as a character is entered in the dropdown list.
It worked fine at first, but now the problem arises when a new item is added to the SharePoint list and when we type this into the search bar it is not automatically inserted into the search bar.

## Diagrams – Minimum basis for the null space of thinly populated matrices

To let $$A in mathbb {F} _2 ^ {m times n}$$ and call their null space as $$V = {x in mathbb {F} _2 ^ m: xA = 0 }$$. The weight of a base $$B = {b_1, dots, b_l }$$ to the $$V$$ is the total weight of the vectors in the base $$| B | = sum_ {b in B} | b |$$, Where $$| b |$$ is the Hamming weight of the vector $$b in mathbb {F} _2 ^ m$$. From all bases for $$V$$Some bases have the minimum weight. We call this the minimum base for $$V$$.

In general, it is NP-difficult to find a minimum basis, because this allows the distance of the binary linear code to be calculated using codespace $$V$$. Given some sparsity restrictions, however $$A$$, the problem of finding a minimum base for $$V$$ can be easy.

For example, if every line of $$A$$ has exactly two nonzero entries (two ones), then a minimum basis for $$V$$ can be produced in $$text {poly} (m, n)$$ Time. That's because $$A$$ can then be interpreted as an incidence matrix for a graph $$G$$ With $$m$$ Edges and $$n$$ Key points. Then the minimal basic problem is tantamount to finding a minimal cycle basis for $$G$$a task that e.g. Horton's algorithm.

This brings me to my main question. Can you say anything about the time complexity of finding a minimum basis for? $$V$$ if every row of $$A$$ has exactly three non-zero entries?

## On Google Sheets – Find the last value in a column if the column is populated by an ARRAYFORMULA

Some columns in my worksheet are filled manually, but then two columns are created dynamically from one ARRAYFORMULA (that is, the column does not contain anything if the manually filled cells are empty, but if they contain data, the values ​​of the other columns are automatically filled in). To find the last value in a manually filled column, I can use a function like the following:

``````=INDEX(H:H,COUNTA(H:H),1)
``````

However, if I use the same formula (adjusted for the right column) in the ARRAYFORMULA column, no error will be displayed, but no results will be displayed.

I also tried that:

``````=INDEX( FILTER( H:H , NOT( ISBLANK( H:H ) ) ) , ROWS( FILTER( H:H , NOT( ISBLANK( H:H ) ) ) ) )
``````

This works fine again for a column that is manually filled, but those calculated from an array formula are not populated

If it's useful, my array forum in I2 is as follows:

``````=ARRAYFORMULA(IF(B2:B, B2:B-H2:H, ""))
``````

How do I find the last value in column I?

## Windows Server 2016 – Active Directory Domain Services Installation – DNS is not automatically populated

I have a Windows Server 2016 server on which I have installed the Active Directory Domain Services role. Which in turn installs the "DNS server" role as a dependency.

I have created a new forest "sales.localhost".

I would have expected Active Directory to automatically create at least one forward search – but is not this the expected behavior?
