Comparison of ISPmanager 6 server panels with Plesk, cPanel and VestaCP.


Each of the panels is easy to manage, but there are so many tools in Cpanel that at first the user will have to use a global search.

All is well in terms of security. All panels have a variety of functions and insertions.

Data backup is also important. ISPmanager has enough functions for saving at each tariff. information can be saved locally or uploaded to a third-party resource and protected with a password.

What can you say about each of these panels and which one would you choose yourself?

Picture Comparison Code Not Working Properly

I am still very much a beginner in programming and am facing a problem with a Java code. I would be very thankful for suggestions and comments. The problem is as following:

I found a Java code online that is designed to compare two pictures and highlight the differences between them. However, the way the code works is by using a loop that compares the RGB value of each pixel of the two pictures and highlights it in a certain color if the value is equal. This however results in a problem that even the slightest shift in camera angle or lighting conditions between the two pictures leads to a different RGB value of the pixels making the code highlight them as a difference even though the pictures are mostly identical. The code is written below and i have added the link to photos showing examples of the outcome of the code. What would you suggest i change in the code? Thank you for your help in advance.

The code:

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;
public class PictureOverlayTest {
/*
* Four variables, three for the wanted BufferedImages, one String for the
* Path of the third Image, which does not already exist.
*/

private BufferedImage image1;
private BufferedImage image2;
private BufferedImage image3;

private String pathImage3;

public PictureOverlayTest(String filePathAndName1, String filePathAndName2,
String filePathAndName3) throws IOException {
/*

* three Strings. The paths and Filenames of all three images. Image 1
* and 2 should exist already, Image 3 will be created if all
* requirements are met. Constructor creates the first two buffered

*/

Color blue = Color.blue;
Color yellow = Color.yellow;

if (image1.getHeight() == image2.getHeight()
&& image1.getWidth() == image2.getWidth()) {

image3 = new BufferedImage(image1.getWidth(), image1.getHeight(),
image1.getType());
for (int y = 0; y < image1.getHeight(); y++) {
for (int x = 0; x < image1.getWidth(); x++) {

int colorImage1 = image1.getRGB(x, y);
int colorImage2 = image2.getRGB(x, y);

if (colorImage1 == colorImage2) {

image3.setRGB(x, y, blue.getRGB());

} else {
image3.setRGB(x, y, yellow.getRGB());
// Whatever Color you want. By default it is black.

}

}
}
savePicture3();
System.out.println(“Message: Image comparison is done”);

} else {

System.out.println(“Error: Image dimensions do not match”);

}

}

private void savePicture3() throws IOException {
/*

File file = new File(pathImage3);

api – Is this string comparison code resistant to timing attacks?

I have to create an API that authenticates a request by checking if the token in the request is equal to the valid token stored in our database. Initially I used the == operator to compare the two tokens, but then I learned that this was vulnerable to a timing attack.

So I wrote the below code in C# to do the token comparison:

static bool constantTimeStringCompare(string a, string b)
        {
            if (a.Length != b.Length)
            {
                return false;
            }

            int result = 0;
            for (int i =0; i < a.Length; i++)
            {
                result |= a(i) ^ b(i);
            }
            if (result == 0)
            {
                return a == b;
            } else
            {
                return false;
            }
        }

Since I am paranoid about “rolling my own crypto” I added the check at the end of the function that does the naïve string comparison to double check that the tokens really are the same. Does doing this open me up to a timing attack? I don’t think it does, as the naïve string comparison only gets run if the xor check thinks the two strings are the same, which will only happen if they really are the same or if there is a really rare bug in the code — the upshot is that it will rarely get run, thus the running time of the function will be constant.

Personally I think it’s a bad idea for me to be doing this (we should be using client certificates), but my company doesn’t care.

edition comparison – What are the differences between the two Ghostbusters RPG systems?

I’m trying to ascertain exact differences between these two editions (the ’86 edition subtitled A Frightfully Cheerful Roleplaying Game and the ’89 edition subtitled International), mostly to see if I need one or both editions to play.

West End Games released Ghostbusters International (…) as a single book, and aside from the more elaborate rules (ranges in combat, more detailed rules for how much equipment could be carried, etc.), the advanced game included descriptions for new equipment that debuted in the second movie.

– Ghostbusters Fandom

Are there any more details as to what exactly the more elaborate rules are? The examples in the passage above seem to be additions, not direct changes? The wikipedia doesn’t have any more details.

It does sounds like it should be a stand alone book, but I’m not completely certain. Does that mean I can’t use the supplements from the previous edition, or are the system differences small enough that they still work together?

Image overlay and comparison code error.

I am still very much a beginner in programming, and i am facing an issue with a code that i am hoping someone could help me with. I found the java code below for overlaying and comparing the pixels of two images in an online forum. When i try to compile the code i get a syntax error. Hope you can help me find the error. Here is the link to the three images showing the errors that i am getting ( https://postimg.cc/gallery/fJZW2k5 ). Thanks in advance.

python – OpenCV face recognition quality in comparison to iPhone like true Depth Camera

I chanced upon a guide to using OpenCV and Python to do face recognition here. This looks pretty cool. On my iPhone, I can log in through face recognition, which I set up by constantly rotating my face around. If I understand it correctly, the iPhone camera is what they call a true depth camera, which takes an Infrared mapping of my face.

My questions:

  1. Will the OpenCV method (involving deep learning) will be in general as quick and accurate as the iPhone true depth camera?

  2. Will it be able to detect twins, or somebody wearing glasses while original photo did not have one (and vice vera) like iPhone true depth camera does?

  3. Is there overall more sophisticated method to do face recognition with high accuracy right now?

python – Efficient Comparison Of Two Images Using Numpy

I want to compare 2 images using numpy. This is what I have got so far.
One of the outputs should be a white image with black pixels where pixels are different.

I am sure it’s possible to make it more efficient by better use of numpy, e.g. the for loop can be avoided. Or maybe there is a function/package that has implemented something similar already?

 import gc
 import PIL
 import numpy as np

 def compare_images(image_to_test_filename, image_benchmark_filename):

  print('comparing', image_to_test_filename, 'and', image_benchmark_filename)

  image_benchmark = plt.imread(image_benchmark_filename)
  image_to_test = plt.imread(image_to_test_filename)

  assert image_to_test.shape(0) == image_benchmark.shape(0) and image_to_test.shape(1) == image_benchmark.shape(1)
  
  diff_pixel = np.array((0, 0, 0), np.uint8)
  true_array =  np.array((True, True, True, True))
  diff_black_white = np.zeros((image_benchmark.shape(0), image_benchmark.shape(1), 3), dtype=np.uint8) + 255
  is_close_pixel_by_pixel = np.isclose(image_to_test, image_benchmark)
  nb_different_rows = 0
  for r, row in enumerate(is_close_pixel_by_pixel):
    diff_indices = (c for c, elem in enumerate(row) if not np.all(elem == true_array))
    if len(diff_indices):
      diff_black_white(r)(diff_indices) = diff_pixel
      nb_different_rows += 1

  dist = np.linalg.norm(image_to_test - image_benchmark) / (image_to_test.shape(0) * image_to_test.shape(1))

  if nb_different_rows > 0:
    print("IS DIFFERERENT! THE DIFFERENCE IS (% OF ALL PIXELS)", dist * 100)
    im = PIL.Image.fromarray(diff_black_white)
    im.save(image_to_test_filename+'_diff.png')
    del im

  del image_benchmark
  del image_to_test
  del diff_black_white
  
  gc.collect()

  return dist, None

edition comparison – What are the differences between versions of Mouse Guard?

I have the hardcover first edition of Mouse Guard, and I’ve been trying to determine what differences there in content between the book, the box set and the second edition versions of both. Answers I’ve found online seem to suggest very little, but don’t go into much detail.

So what are the rules, layout, organisational and narrative differences between the four versions? Do both box sets come with the cards? Is it worth buying the second edition, even as a PDF, if I have the original? Are there any additional materials available that are only compatible with one edition or the other?

Comparison site for EU SIM cards?

Now the EU has waived roaming fees, one can buy a SIM from any of the EU countries. I am sure I am not alone in just wanting the lowest data prices when I visit. Is there a comprehensive comparison of prepaid SIM cards in the EU?

web development – WordPress & M360 Comparison

We are going to revamp our website completely, it’s a news website with hundreds of more pages being added. Currently we are using word press, but recently someone told me about M360 from Times Internet Company. Can anyone in detail share their experience with M360 or if it’s in any way better than Word press. If anyone can share comparison chart, it would be great. Also tell me if anyone using word press should shift to M360?

Thanks
