custom post types – Recoverable fatal error – WP_Post class object could not be converted to string

I am using ACF and trying to display a post type title based on the current time. So I have my post type input with start_time and end_time and my conditional shows my div.onAir, but I get this recoverable fatal error. Here is my code:

 'shows',
      'meta_query' => array(
        array(
          'key' => 'start_time',
          'compare' => '<=',
          'value' => $time_now,
          'type' => 'DATETIME',
        ),
        array(
          'key' => 'end_time',
          'compare' => '<=',
          'value' => $time_now,
          'type' => 'DATETIME',
        )
      ),
    ));
  if( $shows ) {
    foreach( $shows as $show ){ ?>
       
Currently On Air:

I feel like I'm close, but I haven't seen this particular error before. Any help would be appreciated! Thank you.

memory management: why are primitive types stored in a stack in system level software?

First 2 disclaimers, I am very new to the concept of a low level stack. I've only found it because I'm learning rust and the documents mention it. Second, I am aware of another similar question on this site, but it does not address a very specific concern.

My understanding of a stack is that it follows First In Last Off and cannot be searched, this confuses me if I do this.

variable a = 22;
variable b = 33;
variable c = 44;

So I understand that c will be on top of the pile. So if I want to do something with a and b, will the system have to reveal c and drill down on a and b? This seems inefficient. And an indexed array looks better.

7 – How to hide the body field in a view only in certain types of content

I have a search results view of different content types, and I want to display the body field (trimmed) on some content types, but no body on other content types. Since they all share the same body field, I would need to exclude content types from displaying bodies that I don't want to see.

Right now I am doing this through the Views hack with rewrite results. I add the content type field and exclude, then add the body field. Under rewriting results, I rewrite the output of the body field with this:

(body)

Then I hide the content type bodies I don't want to see with css:

span.search-body-MY-NODE-1,
span.search-body-MY-NODE-2 {
  display: none;
}

This works "visually", but the class and the trimmed body are still rendered in the HTML. Is there a better way to do this with a theme hook?

(I am completely inexperienced with PHP).

Custom post types: change the order of menu items

Here is an example of one way I have managed to edit them:

function wpse_custom_menu_order( $menu_ord ) {
    if ( !$menu_ord ) return true;

    return array(
        'index.php', // Dashboard
        'separator1', // First separator
        'edit.php', // Posts
        'upload.php', // Media
        'link-manager.php', // Links
        'edit-comments.php', // Comments
        'edit.php?post_type=page', // Pages
        'separator2', // Second separator
        'themes.php', // Appearance
        'plugins.php', // Plugins
        'users.php', // Users
        'tools.php', // Tools
        'options-general.php', // Settings
        'separator-last', // Last separator
    );
}
add_filter( 'custom_menu_order', 'wpse_custom_menu_order', 10, 1 );
add_filter( 'menu_order', 'wpse_custom_menu_order', 10, 1 );

I have found using this plugin to be the simplest, you can also rummage through the code to see how they do it: https://wordpress.org/plugins/admin-menu-editor/. It is a free add-on!

optimization: can all types of computational problems be modeled as decision problems?

Can all types of computational problems (search, count, optimization …) be modeled as (sets of) decision problems? Reformulation: For each type of computational problem, is there a set of decision problems that if you solve those problems get the result of the original problem?

colloquially: can all types of questions you can ask a chain be answered with (a series of) question results YES NO … So the game is: you are given a question about a chain and only allowed ask the string YES NO questions and answer those that are computable. Can you compose all the answers you get to limit yourself to ONE answer to the original question (not an extension of answers / this result, but with some probability).

Decision problems can be modeled as word-to-language membership. On the surface, this only models the functions ranging from f: {0,1}-> 1 not all other types of functions. Some f: {0,1}-> {0,1} for example. But I have a feeling the answer could be yes …

Does anyone have a clue or proof?

SQL Server 2017: parsing column types of columns used in joins

Is it possible to do deep type analysis on the basis of source code, views and stored procedures to identify column joins that don't have compatible types?

I inherited a database that has not been consistent in using varchar vs nvarchar columns. And sometimes numeric columns are joined with text fields that contain numbers. There are now a few changes that bring more tables into the database with millions of records, and any discrepancies in joined types can have a big impact on performance. These tables have varchar fields and cannot be changed to nvarchar (they are populated by a third party product that does not support varchar).

The options I have:

  1. Convert all varchar columns to nvarchar. Unfortunately, it is not possible. That would have been my preferred option.
    1.b Convert all columns nvarchar to varchar. Hmmm … I feel like this is a rabbit hole that I probably don't want to get into, although all text data is supposed to be in English.
  2. Use the MS Transact SQL (DacFx) parser to parse the queries, however I think this will require significant programming effort. You would need a complete list of all sql server functions and the types they return.

Any other idea?

Thank you

Using encryption that produces random memory / storage, can you randomly enter memory / data that is read as known file types?

I mean the answer to this question, the second part mentions the random data and not headers or anything including files that are recognizable. Reading the answer made me think that adding data from random files would only increase security.

If an encryption method makes all the data (by viewing the HEX values) random, wouldn't it add an additional level of security for the encryption algorithm to add the values ​​of random and known file types, in random locations, and selecting the default known file type types (.PNG,. Jpeg, .TXT and more) and placing a random number of random file types (randomly selected from the list or known file types / extensions), in random places. Perhaps by not placing them in areas that generally contain headings and other information. So it wouldn't be 100% random, because you need to know the types of files being added, and a possible pseudo-random algorithm on the frequency or quantity, simply because you can't have the randomness producing too many of these bogus extensions, and not the I want it everywhere, I guess that would not be good. Just based on memory?

I feel like if you can add a certain degree of questions from whoever is examining it, that not everything is random, that would add security because they couldn't determine that it is random data, because the file traces. Ultimatley makes it more difficult to determine what's on a hard drive or SDD or even files.

sharepoint server: migrate a subsite with content types

I have a large subsite within a Sharepoint 2016 site hierarchy that I would like to export to a different site collection. The problem is that each document set library on the subsite uses a single content type that was created at the primary level of the subsite. E.g. If my site is at http: // example / type / site, the content type and columns are configured on the http: // example / type site.

I tried using import / export-spweb to copy the site and its content to the new location, but it only moved the secondary content types as part of the libraries. How can I move the content type and columns of the primary site and re-associate them with the secondary content types? And can I preserve any additional columns or column hides present in secondary content types?

I'm comfortable enough with Powershell to import scripts of the content type / columns or update them on child elements, given some idea how to do it without missing customizations or more.

data tables: save functionality with input of multiple data types

I apologize if the title of the question seems unclear. I have a commercial application with multiple input / data types on the same screen:

  1. A couple of "basic" text input and drop-down menus. These fields are
    normally configured / saved first, and everything else can be completed
    then. Users have the ability to go back and change values.
  2. A single long text area (requiring a WYSIWYG)
  3. An editable table, where one of the column fields includes a 500
    max textarea of ​​character

Given the different types of data, what would you recommend to handle the save functionality?

My initial thought was editable pop-ups for table rows (# 3), as inline editing would not work well with the text area field. Similarly, would it make sense for the long text (# 2) to initially show up as a read-only paragraph with an edit button that will open a WYSIWYG popup? If so, would auto save be considered in that field?
Since the last two parts are popup windows, I am very tempted to have a popup edit for the basic fields (# 1).

Would it make sense? Am I doing things too complicated?
