linux – On an Azure hosted RHEL instance, how could the Tomcat service get started as root when the .service file specifies a user?

We have 3 RHEL servers running in 3 different Azure regions.
All 3 have been running Tomcat, as a service, as the expected non-root user that is specified in the .service file, for months.

On the 25/26th May all 3 started running the tomcat service as root.
Restarting the service and systemctl demons-reload did not fix the problem.
Rebooting the box did fix the problem.

Any ideas how such a situation could occur?
Azure SNAFU or bad actor?
How worried should I be?

woocommerce offtopic – Hook that specifies an action code is only applied to a certain product category slug or product ID number

I have some code running globally on my website that places a notation between my product variation and the add to cart button, however, I do not want it to appear globally, but rather only applied to particular Product Category Slugs or Product ID’s.

I’ve tried what seems like a million different things to make it happen, but the code still appears on every product/category I have published.

The code is as follows:

add_action( 'woocommerce_before_add_to_cart_button' , 'aj_add_below_prod_var', 5 );
 
function aj_add_below_prod_var() {
    echo '<span style="font-weight:bold; color:red;"> Quantities are in HALF YARD increments. (1=1/2 Yard, 2=1 Yard, 3=1 1/2 Yards, etc.) </span>';
 }

Can anyone help? I only want it to appear on the products that are in the
category slug ‘pre-order-fabrics’

Thanks so much for any assistance! I posted over in the WordPress.org/support/plugin/woocommerce group and they referred me over here.

cyberpunk 2020 – What book specifies rules for running fast on paired cyberlegs?

In Cyberpunk 2020, suppose you have a team with three members: Apple, Banana, and Canteloupe.

Movement Allowance {MA): This is an index of how fast your character
can run (important in combat situations). The higher your Movement
Allowance (MA), the more distance you can cover in a turn. RUN: To
determine how far your character can run in a single combat round
(@3.2 seconds) in meters, multiply your MA by 3. The character can run
three times this distance in a full 10 second turn. Write this in the
RUN section of your Hardcopy Form. LEAP: To determine how far your
character can leap (from a running start), divide your RUN by 4.
Write this in the LEAP section of your Hardcopy Form.

(p.26, 2020 rulebook)

The Solo, Apple, starts with a Movement Allowance of 2.
This means he can run 6 meters in 3.2 seconds and his RUN score is 18; that is, he can run 18 meters in 10 seconds. His LEAP stat is 18/4=4.5; this means he can do a running jump of 4.5 meters.

His friends, Banana and Canteloupe, have Movement Allowances of 3 and 4. They have RUN scores of 27 and 36; thus they have LEAP stats of 6.75 and 9, respectively. Because the basic rules do not mention vertical leaping, I assume that they cannot vertically leap to any major extent.

This solo, Apple, gets paired cyberlegs.

“Characters with paired cyberlegs can leap 6 meters straight
up, or make a running jump of up to 8 meters.”

(p. 89, 2020 rulebook)

This means that Apple effectively has a LEAP stat of 8. Assuming consistent equations, Apple’s RUN score should be 32. So Apple can run faster than Banana but is still slower than Canteloupe.

As far as I can tell, even though Apple can leap vertically, he is not protected from most falling damage. (If I were GM, I would say because he can leap up 6 meters, he can also fall 6 meters without taking damage IF he lands on his feet, but would take ordinary falling damage if he failed to land on his feet. I can’t find anything in the rules about that.)

As play proceeds, Apple wants to modify his legs so that he can run very fast. In the core rulebook, I cannot find any rules covering this. Some old R. Talsorian books probably have various rules. Which books have rules for running?

assembly – What specifies the agreement (i.e. the convention) of which registers are used to pass which arguments and to return which values?

In Computer Systems: a Programmer’s Perspective:

procedure calls may involve
passing data as arguments, and returning from a procedure may also
involve returning a value. With x86-64, most of these data passing to
and from procedures take place via registers. For example, we have
already seen numerous examples of functions where arguments are passed
in registers %rdi, %rsi, and others, and where values are re- turned
in register %rax. When procedure P calls procedure Q, the code for P
must first copy the arguments into the proper registers. Similarly,
when Q returns back to P, the code for P can access the returned value
in register %rax. In this section, we explore these conventions in
greater detail.

enter image description here

Is it correct that a caller and its callee procedure must agree on which registers to be used to pass which arguments and which registers to be used to return which values?

What specifies this agreement?

  • The procedure to be called (so different procedures specify different agreement which callers must agree on?)

  • The assembly language (so different assembly languages specify different agreement which procedures and callers must agree on?)

  • The machine language (ISA) (so different machine languages specify different agreement which procedures and callers must agree on?) ?

What specifies the particular convention in the example and the figure in the quote?

Import Export – Drupal 8 specifies how to set a URL alias for nodes created by items imported through the Feeds module (RSS feed)

In Drupal 8 I have nodes of the item type with the module & # 39; Feeds & # 39; created. The source is RSS feed. How can I create a URL alias for each node created for each element?
I tried source: & # 39; Element URL (Link) & # 39; Target: & # 39; URL alias (path) & # 39; assign. It doesn't work because it contains the entire link (including http: // …) as an alias.

Measure Theory – Help understand the proof of the measurability of a function that only specifies a class of sets that produce the Borel Sigma algebra

The following question may be too simple for many people and concerns about a very basic doubt, which I certainly miss somehow, but I would be happy if someone could help me clear up my confusion a little.

To let $ mathcal {B} $ denotes the Borel $ sigma $Algebra on $ mathbb {R} $ and let $ (S, Sigma) $ be a measurable space with the crowd of all $ Sigma $-Measurable functions denoted by $ m Sigma $. Then sentence 3.2 (b) of the book Probability with martingales by David Williams notes the following

To let $ mathcal {C} subseteq mathcal {B} $ and $ sigma ( mathcal {C}) = mathcal {B} $. Then $ h ^ {- 1}: mathcal {C} to Sigma $ implies that $ h in m Sigma $.

The proof continues by showing that the class of sets $ mathcal {A} = {A in mathcal {B}: h ^ {- 1} (A) in Sigma } $ is a $ sigma $-Algebra contains $ mathcal {C} $ and is therefore the same $ mathcal {B} $Set the desired result. Although the proof is very simple, I am confused to see that the author does not show this during the proof $ mathbb {R} in mathcal {A} $, or equivalent, $ Emptyset in mathcal {A} $.
I've seen the same type of evidence in some other books, which means this must be something trivial, but I don't understand how to show it $ h ^ {- 1} ( mathbb {R}) in Sigma $ or equivalent, $ h ^ {- 1} ( Emptyset) in Sigma $ unless $ mathbb {R} in mathcal {C} $ or $ Emptyset in mathcal {C} $. Somehow it has to do with that $ sigma ( mathcal {C}) = mathcal {B} $? Can someone help? Thank you in advance.

python 3.x – The most frequently repeated string in a list and specifies the index at which each instance begins

So I wanted to write a script that essentially prints the longest repeated string in the entire list. So far I have received:

import re
import collections

#-----------------

def Rep_String(inp):
    words = re.findall(r'w+', open(inp).read().upper())
    commons = collections.Counter(words).most_common(4)
    #print("The most commmon string reapititions are as follows: ", commons)

def main():

    inp = input("What's the file? ")
    file = open(inp)
    #f = file.readlines()
    liste = ()
    for i in file:
        liste.append(i)
    new_liste = (x(:-1) for x in liste)
    print(new_liste)

    Rep_String(inp)


if __name__ == "__main__":
        main()

After the most common repeated string is found, the script should also provide the index number where each repeated instance is in the list. But the list itself is cumbersome:

The correct result should be "BEMXBICCLISO" because it is the longest repeating string that repeats four times in the list. I understand that I am missing an index command, but I am more concerned with the script's repeating string function and am really more of a convenience to the script than a necessity. The output is strange and I can't see where I made a mistake with this. I hope everyone can help me with this and any guidance is welcome to help everyone.

php – How to put in an array at a position specifies the values ​​of an input text

I need to retrieve the values ​​contained in an input text in a form, and each time the user clicks Submit Submit below that input, I must put that value into an array and display the current value on the screen. However, I can not do this without having to change sides. I try to repeat to test my logic, and nothing happens.
