## Automatically add Link Images to Posts in WordPress if has not linked before or has specified class

I use this code to Automatically add Link Images to Posts in WordPress.

``function wpguy_linked_image(\$  content){ if (is_single() === TRUE){ \$  searchfor = '/(<img[^>]*\/>)/';   \$  replacewith = '<a target="_blank" href="'.get_permalink().'">\$  1</a>'; { \$  content = preg_replace(\$  searchfor, \$  replacewith, \$  content); } } return \$  content; } add_filter('the_content', 'wpguy_linked_image'); ``

## Instantiate prefab on specified position of GameObject on scene

I have a room that I want to connect to a staircase. Both the room and the stairs have the following parameters:

I need to "magnet" the "Room Exit" position of the room (start room) to the "Room Entry" staircase. The staircase itself, I create through Instantiate

How can i do this?

## Why SQLMap Doesn’t Attack Specified Parameter?

I am new to SQLMap. I have setup Kali and OWASPBWA VM. Both VMs are on same NAT Network set in VirtualBox.

When I try to run following command:

``sqlmap -u "http://<IP_ADDRESS>/mutillidae/index.php?page=user-info.php?username=111&password=bbb&user-info-php-submit-button=View+Account+Details" -p username ``

I get following messages:

• Previous heuristics detected that the target is protected by some kind of WAF/IPS.
• Multiple messages – Unable to connect to the targeturl. sqlmap is trying to reconnect.
• heuristics test shows that GET parameter ‘username’ might not be injectable.

There are several YouTube videos which display same setup with above 2 VMs, and are able to run the command and find injection in username parameter. What am I doing wrong? Please help.

## Does Nmap use only one of the DNS servers specified in the –dns-server flag per host?

When I’m scanning with Nmap, I make an effort to get proper hostnames associated with the target IPs. To do this, I scan UDP 53 on the targets to identify DNS servers and then run something like the following for each identified DNS server:

``nmap -sL -v4 --dns-servers DNSSERVER TARGETS ``

I have to review the results for each tested DNS server to see how many of the targets it can resolve, and also determine if the resolved targets differ.

The docs seem to imply that if you specify multiple servers in the `--dns-servers` flag, that it will choose one at random (or round robin). This interpretation comes from the "is often faster" part.

The problem I have is that my scan targets may not all be supported by the same DNS server. In my case, I’d rather specify all identified DNS servers in `--dns-servers` and have it fail over until it finds one that returns a response. If only one of the specified servers is used, to get accurate results I would need to perform multiple scans, each with a single DNS server specified.

My question is, is it true that the `--dns-server` flag will use only one of the specified DNS servers, and not try them all?

## Complexity of Subset Sum where the size of the subset is specified

I know it should be easy but I’m trying to determine the complexity of the following variant of Subset Sum.

Given a subset $$S$$ of positive integers and integers $$k>0$$ and $$N>0$$, is there a subset $$T\subset S$$ such that $$|T|=k$$ and the members of $$T$$ sum to $$N$$ ?

All of the formulations of subset sum that I’ve seen don’t specify $$k$$ so I’m wondering if this problem can be solved in polynomial time. If $$k$$ is fixed for all instances, then I know that the problem is in P and solvable by brute force in $$O(n^k)$$ time. However, I’m allowing $$k$$ to vary from instance to instance.

I tried to run AceGen/AceFEM on my Mac(10.15.5). I installed Mathematica (12.1.0.0) successfully and also the latest version of the AcePackage (7.113). The installation of the AcePackage is successful, saying the C compiler is found. Now I can build an element (from the MainLibrary) for example, but running a simulation is not possible. Both packages can be loaded, but executing the `SMTInputData[];` command gives the following error.

``LinkOpen: Specified file is not a MathLink executable..  External numerical module is closed. Please restart Mathematica and try again. If the error repeats rebuild and recompile all user elements in debug mode. ``

What can I do?
