Well written fake review articles …

I need experienced copy writer is to find some product on Amazon that has plenty of reviews and then write fake reviews for that product as if you bought the product. Write bad reviews, good reviews, neutral reviews. Our lab at school compares them to the real ones.
I am in charge of getting reviews done and I need a lot from what I was told.
We also need a them written for many categories like lawn care, auto parts, toys,…

Well written fake review articles …

XSS exploitation tools written in PHP/python comparable to BeEF [on hold]

I asked already a similar question. But for most it was not clear what I was asking about. Now I try my best and clarify as much as possible.

I tested XSS-exploitation tools: JSShell, BeEF, xssshell-xsstunnell and JShell. But was not satisfied (reasons below).

BeEF and co. are simply “command & control” (C&C) tools (with some extra exploits added as bonus) which obviously need to run on a public server to create a “communication channel” between an attacker and a victim. Now BeEF is written in ruby, but most websites are using PHP (79.1% in 2019) and often have also natively python installed. Many hosting providers don’t give you root access. That makes it a bit odd that someone comes to idea to write C&C in ruby or even in ASP.NET since one would expect it to be written in PHP or python.

I wanted to bypass such restrictions (if even possible?) and still (!) use it on my local machine but allow it being accessible from the the outside. Yes! By using VPN and reverse proxy: https://serverfault.com/questions/979393/hosting-files-on-local-machine-behind-a-nat-which-can-be-accessed-from-public-se But I will need to test it and as far as haven’t tested it remains an open problem for me and I will just try existing tools.

Question:

Are there any C&C tools which are comparable in quality to BeEF (since it offers many useful features which I miss in other tools which I tested so far) but written in PHP or python? Most tools which I’ve seen so far aren’t comparable in quality to BeEF or written in other scripting languages or for other platforms like Windows Server. I googled but maybe I’m overlooking something.

Because currently it appears to me that if you want to fully exploit XSS you need to rent a server which supports ruby or ASP.NET. This is absolute valid, but not far from ideal.

How can we convert between a program using `call/cc` and a program using functions written in CPS?

The Scheme Programming Language says

It turns out that any program that uses call/cc can be rewritten in CPS without call/cc, but a total rewrite of the program (sometimes including even system-defined primitives) might be necessary.

What are the general techniques to

  • convert a program using call/cc to a program using functions written in CPS

  • convert in the reverse direction?

How can I match handwritten character segments (including the direction they are written)?

I am trying to test Chinese character production by having users draw the characters on their device. There are plenty of data models that include the character information already, so I will have that. My question is, how do I check if the user drew the stroke that is expected (with some sort of threshold value). Some of these segments may have curves in them, which makes it a little more difficult than just line matching. I have a video here demonstrating what I’d like to achieve. Notice how if I draw the wrong segment, or in the wrong direction, it is not accepted.

How exactly should unit tests be written without mocking extensively?

As I understand, the point of unit tests is to test units of code in isolation. This means, that:

  1. They should not break by any unrelated code change elsewhere in the codebase.
  2. Only one unit test should break by a bug in the tested unit, as opposed to integration tests (which may break in heaps).

All of this implies, that every outside dependency of a tested unit, should be mocked out. And I mean all the outside dependencies, not only the “outside layers” such as networking, filesystem, database, etc..

This leads to a logical conclusion, that virtually every unit test needs to mock. On the other hand, a quick Google search about mocking reveals tons of articles that claim that “mocking is a code smell” and should mostly (though not completely) be avoided.

Now, to the question(s).

  1. How should unit tests be written properly?
  2. Where exactly does the line between them and integration tests lie?

Update 1

Please consider the following pseudo code:

class Person {     constructor(calculator) {}      calculate(a, b) {         const sum = this.calculator.add(a, b);          // do some other stuff with the `sum`     } } 

Can a test that tests the Person.calculate method without mocking the Calculator dependency (given, that the Calculator is a lightweight class that does not access “the outside world”) be considered a unit test?

Magento 2.2.7 Pagination Block not being written to page on search results

Pagination works fine on other pages but when I do a search and the results are posted, in this case more than 20, there are no paging controls displayed at the bottom and the block hasn’t been output onto the page (/catalogsearch/result/index/?product_list_dir=asc&q=electric+jack) so it’s not a css thing and I can’t tell where I should be looking. Fairly new to Magento so it’s still confusing 🙂

WordPress 4.4.2 upload give error, can’t write is upper directory allowed to be written

I searched around for this problem en found a lot of ideas most has to do with write access. The idea is: Put all directories in the wp-content/upload to 744 if not work to 755 and all the files to 644 (like this one for example: https://www.wpbeginner.com/wp-tutorials/how-to-fix-image-upload-issue-in-wordpress/). And some even said 777 looks to me a bit of a over kill but, I tried and it didn’t work as well. I keep getting the some error.

Empty cash of browser and from WordPress it self. Didn’t do the trick.

The rights to the directories is to the user and the root so I would say the the system has all access to the directory. I have ssh access to change if needed.

Even if i write a small code to copy a image from a uploaded image. It made a new directory in wp-content/upload and it did copy the file. But when i try it with WordPress it still fails.

Does anyone has a idea of what I can try more?

Is C the fastest language because most kernels are written in C viz. Unix, DOS and Macintosh?

Hypothetically if there were an OS named YAOS(yet another OS) written in ALWAC (Another language with another compiler), assuming ALWAC is assembly optimized of course. Would ALWAC be comparable to C in performance, given that C is the fastest language that there is.

To rephrase the question: Would it be a good idea to write a language specifically for a kernel plugin like Symbian OS, Purity OS or Nutanix OS to speed up the development without compromising C like performance? A language native to an OS/kernel module, if you will. I mean, C came after Unix, historically, which is what raised this doubt.
