network – Snort analyze reply based on request

I’m trying to write a snort rule which detects if certain binary files where requested via HTTP based on a regex rule matching there names.
But it should only send an alert if the file exists (e.g. HTTP 200 OK reply).

Is it possible to have this kind of “statefull” scan?
What kind of technique could I use else since the files have no reliable information in them I could search for.

The current look of my rule:

alert TCP $EXTERNAL_NET any -> $HOME_NET $HTTP_PORTS (pcre:"/d{6}-d.d.pdf$/U"; sid:90000512; classtype:patent-access;) 

When should run Analyze table statement in mysql

Hello DBA’s i have also some question
1/ Why should we never run ANALYZE TABLE?
2/ How do I know for sure this table/db needs to be analyzed ? It seems that MySQL doesn’t store when the last time “stat” was updated ?

Just for Example :-
Assume i have queried

+-------+------------+----------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+---------------+
| Table | Non_unique | Key_name | Seq_in_index | Column_name | Collation | Cardinality | Sub_part | Packed | Null | Index_type | Comment | Index_comment |
+-------+------------+----------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+---------------+
| goods |          0 |  PRIMARY |            1 |          id |         A |     7765796 |     NULL |   NULL |      |      BTREE |         |               |
| goods |          1 |  shop_id |            1 |     shop_id |         A |       14523 |     NULL |   NULL |      |      BTREE |         |               |
| goods |          1 |  shop_id |            2 | create_date |         A |      168168 |     NULL |   NULL |  YES |      BTREE |         |               |
+-------+------------+----------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+---------------+
3 rows in set (0.00 sec)```
So to see this output,how do i get to know for this table need to run analyze table command  ?

SQL Server – SSIS 2017 – Analyze a flat file with several columns and headers on several lines

I receive a daily CSV file which contains more than 600 positions of company employees, each of which is formatted as follows:

Position,Description
SUP1015,Shipping Supervisor Day
Work UOM:,Hours,Active:,Yes,Permanent:,Yes,,
Default Rate Level:,0,Default Rate Source:,Master,Default GL Source:,Master,,
Effective Date:,,Expiry Date:,,Created Date:,29-Apr-2014,Revised Date:,06-Jun-2019
Job Class:,,,,,Location:,,1004 - Shipping,,
Union Code:,,,,,Reports To:,,MGR1056 - Delivery & Shipping Manager,,
Position FTE:,,1.0000,,,,,,

My goal is to transform the 600+ records into a single table:

Position | Description                     | Work UOM | Active | Permanent | Default Rate Level | Default Rate Source | Default GL Code | Effective Date | Expiry Date | Created Date | Revised Date | Job Class | Location                 | Union Code | Reports to                                    | Position FTE |
=========================================================================================================================================================================================================================================================================================================================
SUP1015  | Shipping Supervisor Day         | Hours    | Yes    | Yes       | 0                  | Master              | Master          |                |             | 29-Apr-2014  | 06-Jun-2019  |           | 1004 - Shipping          |            | MGR1056 - Delivery & Shipping Manager         | 1.0000       |

I have no idea how to analyze this, given the connection managers in SSIS. Any help and advice is greatly appreciated.

real analysis – Analyze a complicated double summation

Let $ f (x) $ be a function with real value twice continuously differentiable, and considered as the double sum below $$ F (t, f (x)): = dfrac {1} {t} Big ( sum_ {k = 0} ^ { infty} sum_ {m = 0} ^ { infty} f ( x + (km) / sqrt {n}) dfrac {t ^ {k + m}} {2 ^ {k + m} k! m!} e ^ {- t} -f (x) Big) . $$ I want to calculate the limit of $ F (t, f (x)) $ when $ t rightarrow 0 $, but I don't even know where to start …

My idea was to write this double sum in two parts, the first part can be our desired answer and the second part can be null when $ t rightarrow 0 $, but I don't know what to do to analyze such a complicated sum …

An idea?

How to analyze and correct the google test of the form "The page is not suitable for mobiles"?

I work on a website and when I test for mobile compatibility Google shows these errors.

  • Content wider than the screen
  • Clickable elements too close together

I do not know what elements give this error?
And also if the content wider than the screen is for the table with the horizontal scrolling, then how can I solve this problem because this data is a little bigger and cannot be adapted to the screen ..

c – How to analyze a more efficient command line entry?

in the main() based on the following code, i wrote a very naïve command analysis. Is there a more effective way?

This program aims to ADD, SUB, MUL, DIV these four arithmetic operations for integers. The entry would be in the following form: ADD 1 1, MUL 12 90. And there would also be a special input character % which means using the last result. For example, ADD 1 1 would return 2, then ADD % 1 would return 3.

#include 
#include 
#include 

typedef int (*calc_function)(int, int);

typedef struct operation {
        char *name;
        calc_function calculate;

} Operation;

int add(int a, int b) { return a+b; }
int sub(int a, int b) { return a-b; }
int mul(int a, int b) { return a*b; }
int divi(int a, int b) { return a/b; }


int calc(int a, int b, int (*c)(int, int)) {
        return c(a, b);
}

int main() {

        char *command = malloc(9);
        int result = 0;
        int a;
        int b;

        Operation ADD = {"ADD", add};
        Operation SUB = {"SUB", sub};
        Operation MUL = {"MUL", mul};
        Operation DIV = {"DIV", divi};

        Operation ops(4) = {ADD, SUB, MUL, DIV};

        while((command = fgets(command, 9, stdin)) != NULL) {

                for(int i = 0; i < 4; ++i) {
                        if (0 == strncmp(ops(i).name, command, 3)) {
                                command = strchr(command, ' ');
                                command++;
                                if (*command == '%') {
                                        a = result;
                                } else {
                                        sscanf(command, "%d", &a);
                                }
                                command = strchr(command, ' ');
                                command++;
                                if (*command == '%') {
                                        b = result;
                                } else {
                                        sscanf(command, "%d", &b);
                                }
                                result = ops(i).calculate(a, b);
                                printf("%dn", result);
                        }
                }
        }
        free(command);

        return 0;
}

In addition, any advice on improving the performance and style of this program would be greatly appreciated!

Analyze the array in a chain and get the value to display in html

I have made a few changes to a plugin that returns me an array with several vaues and an array inside.
I tried to get the value of the array to display in a table, but I didn't find the right way to do it.
Here is the code I created to display the output:

    foreach ( $arr as $num => $el ) {
        $arr( $num ) = maybe_unserialize( $el );
    }

    $is_added = isset( $post_meta( $meta_key ) ) ? false : true;


    echo $is_added ? '' : '';
    echo '
' . esc_html( $meta_key ) . '

"
echo & # 39;

' . esc_html( var_export( $arr, true ) ) . '

". " not";

}

echo & # 39;

"

The output is:

array (
  'sampleemail@gmail.com' => 
  array (
    'leads' => 
    array (
      'name' => 'Mark',
      'phone' => '',
      'message' => 
      array (
        0 => 'Good Morning',
        1 => 'Hi Jack',
      ),
      'time' => 
      array (
        0 => '13 April 2020',
        1 => '16 April 2020',
      ),
      'extras' => NULL,
    ),
    'status' => 'unread',
    'replies' => 
    array (
      'message' => 
      array (
        0 => 'ok',
      ),
      'time' => 
      array (
        0 => '16 April 2020',
      ),
    ),
  ),
)

I want to get all the data in the array and convert it to a string to display formatted in an array, instead of displaying the array as before. What's the best way to do it? Is it better to convert it to json format?

SQL Server – Why analyze a clustered index rather than looking for a nonclustered index?

There is an SQL script:

CREATE TABLE users 
  ( 
     id        INT, 
     firstname VARCHAR(50), 
     surname   VARCHAR(50) 
  ); 

CREATE CLUSTERED INDEX ix_users_id 
  ON users (id); 

CREATE NONCLUSTERED INDEX ix_users_firstname 
  ON users (firstname); 

SELECT firstname, 
       surname 
FROM   users 
WHERE  firstname = 'John';

I don't understand why for the SELECT request above, the SQL Server 2019 engine selected follows the execution plan:

enter description of image here

Why is the clustered index analyzed? I thought, faster is:

  1. search for the non-clustered index;
  2. move to a clustered index by clustered index pointer, which
    storage in the leaf node of the nonclustered index;
  3. and take rest surname value from there.
