How can dash be used as a main action if actions and bonus actions aren’t interchangeable?

I’ve found two twitter chains that I can’t seem to make sense of.

From Jeremy Crawford:

"Actions and bonus actions aren’t interchangeable." [source]

Also from Jeremy Crawford:

"Double dash in one turn can happen with dash as bonus action." [source]

So how can a rogue use both their action and bonus action to dash twice with [Cunning Action]? It is specified in [Cunning Action] that the [Dash] can only be used with a bonus action.

Prevent block from being used in main editor, use only as inner block

I am currently using the allowed_block_type filter to control the available blocks in my theme, similar to the following example:

function acf_allowed_blocks($  allowed_blocks, $  post) {     // Register core blocks     $  core_blocks = array(         'core/buttons',         'core/heading',         'core/image',         'core/list',         'core/paragraph',     );      // Register custom blocks     $  custom_blocks = array(         'acf/test-block',     );      // Register plugin specific blocks     $  plugin_blocks = array(         'gravityforms/form',     );      // Specify block groupings available on specific post types     switch ($  post->post_type) {     case 'post_type_example':         $  allowed_blocks = array_merge($  core_blocks);         break;     default:         $  allowed_blocks = array_merge($  core_blocks, $  custom_blocks, $  plugin_blocks);     }      return $  allowed_blocks; } add_filter('allowed_block_types', 'acf_allowed_blocks', 10, 2); 

While this works perfectly, I am trying to determine whether or not it’s possible to remove the gravityforms/form block, but allow it inside the acf/test-block. Currently, if I remove the block from this function, it’s also becomes unavailable as an inner block in my ACF block markup, which looks like this:

$  allowed_blocks = array( 'gravityforms/form' ); echo '<InnerBlocks allowedBlocks="' . esc_attr(wp_json_encode($  allowed_blocks)) . '" />'; 

Does anyone have any idea on whether or not this is even possible with the current state of Gutenberg? I can just as easily live with it being available as both a main and an inner block, but it would be my preference to only use it as an inner block.

A 32 – bit wide main memory unit with a capacity of 1 GB is built using 256M X 4-bit DRAM chips

A 32 – bit wide main memory unit with a capacity of 1 GB is built using 256M X 4-bit DRAM chips. The number of rows of memory cells in the DRAM chip is 2^14. The time taken to perform one refresh operation is 50 nanoseconds. The refresh period is 2 milliseconds. The percentage (rounded to the closet integer) of the time available for performing the memory read/write operations in the main memory unit is _______ .

I calculated that the no of DRAM chips needed is 32. Now each DRAM have rows = 2^14
and columns 2^16 also as we can refresh the rows in parallel and since for one memory cell the time is 50 nanoseconds so for 2^16 columns we will need 2^16 * 50 nano sec ?…Is my approach right

or if i consider that 50 nanoseconds is the time for refresh of a complete row then also it would need a total of 50 nanosec to refresh all in parallel

Does the Polearm Master bonus attack have to be used after the main attack?

Using the Polearm Master bonus attack rules:

When you take the Attack action and attack with only a glaive, halberd, quarterstaff, or spear, you can use a bonus action to make a melee attack with the opposite end of the weapon.

Does this additional attack clearly occur after the attack with the main weapon, or is there a time to use it between the attack being "declared" and resolving the main attack?

Background/motivation: I would like to attempt the following:

  1. Announce I am attacking Bandit Keith;
  2. Use the bonus action to attack with my halberd’s shaft, with a Tripping Attack maneuver;
  3. Assuming success on the attack / STR check, attack with the halberd blade at advantage;

While that appears to fit how the flow of a fight works in my head, the word take appears a bit ambiguous to me if I wish to argue from RAW. If an Action is taken does this mean it is completely resolved?

Does every thread have its main function?

Does every thread have its own main function?

I know that its have its own stack, but what about main function (not necessarily a function which called main).

For example, when creating a thread, we pass a function as an argument for the new thread to run it.

I tried to search about this topic, but couldn’t find answers.

Nginx main domain overwriting subdomains

I have an Nginx server running a website, and I’d like to add a new host under a subdomain, to the main domain.

However as the title suggests, the subdomain’s host seems to get ignored, and replaced by the main domain regardless.

Am I correct in assuming that the following statements, each in their own server block: server_name; server_name;

Will always go to
