kandi X-RAY | knock Summary
This is a port-knocking server/client. Port-knocking is a method where a server can sniff one of its interfaces for a special "knock" sequence of port-hits. When detected, it will run a specified event bound to that port knock sequence. These port-hits need not be on open ports, since we use libpcap to sniff the raw interface traffic.

QUESTION
(I know the code is messy - I'll refactor when it works)
This code chucks up an 'Out of Range' error. It worked for days, and then suddenly stopped working and I can't figure out why.
The desired functionality is:
- File dialog and open Excel file.
- Open the workbook
- Copy data in first sheet to clipboard
- Paste into A1 on pre-existing sheet in ThisWorkbook
- Close workbook
Debugging suggests it's OpenBook.Sheets(1).UsedRange.Copy which is failing.
I think I must have knocked something while editing at the bottom of the Sub?
Thanks in advance :)

I want to check the registration field for validation. And it works for me, but if the user enters something wrong, then I get a page with (type = Bad Request, status = 400) and should knock out an SMS with an error in the form itself. what am I doing wrong?

QUESTION
I am creating a short RPG game for my AP CSP project and for some reason when I call the method Element in line 310-313, it just ends the rest of the code in Main (which is all the remaining code in the program). The user is required to press x to continue the game but it skips all of that and auto-fills the user-inputs correctly. Put it short, once you select your element in the code, the program finishes the game by itself, which is not supposed to happen since the user needs to have its input to continue the dialogue.
Aforementioned, the intended output of this code is to complete the dialogue with the user input and user information only. Please help as this is due soon!

I am trying to create a clone of a Postgres table using plpgsql. To date I have been simply truncating table 2 and re-inserting data from table 1.
...ANSWER
Answered 2021-May-21 at 14:11PostgreSQL doesn't provide a very elegant way of doing this. You could use pg_dump with -t
and --section=
to dump the pre-data and post-data for the table. Then you would replay the pre-data to create the table structure and the check constraints, then load the data from whereever you get it from, then replay the post-data to add the indexes and FK constraints.

QUESTION
I am aiming to place a text box in right in the center of the page, and three buttons below it. Now I hope to add a menu bar on top with a few buttons to the right, but when I use flex to align the menu to the top right, it pushes the text/buttons to the left. If I don't align the menu to the right, everything stays centered. I think it's how I'm using flex properties, but I'm not sure how I can ensure the two sections don't knock each other out of alignment.
...ANSWER
Answered 2021-May-14 at 20:54This has nothing to do with your use of flex
properties. The issue was the float: right
on your .topnav
element. When you added that, it floats the element next to the form
element. What you need to do is add clear: both
on the form (.search
).
Also, you had a few gap
properties, which will do nothing for flex items (gap
is for CSS Grid elements), and you can remove the justify-content
property on the topnav
since it's not a flex parent.

I am currently trying to code a linkblocker in discord.js. The link should only be deleted if you are not in the group with the correct ID.
My code:
...ANSWER
Answered 2021-Apr-24 at 20:27That's probably because you are sending a message to the channel after you have deleted it. Maybe it returns member as null because of you being a bot. Just do a simple check, if the message is not coming from you or a bot to see, if that is the problem.

The game of billiards involves two players knocking 3 balls around on a green baize table. Well, there is more to it, but for our purposes this is sufficient.
The game consists of several rounds and in each round both players obtain a score, based on how well they played. Once all the rounds have been played, the total score of each player is determined by adding up the scores in all the rounds and the player with the higher total score is declared the winner.
The Siruseri Sports Club organises an annual billiards game where the top two players of Siruseri play against each other. The Manager of Siruseri Sports Club decided to add his own twist to the game by changing the rules for determining the winner. In his version, at the end of each round, the cumulative score for each player is calculated, and the leader and her current lead are found. Once all the rounds are over the player who had the maximum lead at the end of any round in the game is declared the winner.
...ANSWER
Answered 2021-Apr-22 at 18:14Unless I'm missing something, you don't need to store the scores for each round in an array at all.
You only need a two element array, indexed by player number, to hold the total/accumulated scores
Just remember the "best" round (largest lead) and the player that had it as you read in the data.
Here's what I came up with [it passes the submission for all data]:
QUESTION
I have a large table with a comments column (contains large strings of text) and a date column on which the comment was posted. I created a separate vector of keywords (we'll call this key) and I want to count how many matches there are for each day. This gets me close, however it counts matches across the entire dataset, where I need it broken down by each day. The code:
...ANSWER
Answered 2021-Apr-21 at 18:50As pointed out in the comments, you can use group_by
from dplyr
to accomplish this.
First, you can extract keywords for each comment/sentence. Then unnest
so each keyword is in a separate row with a date.
Then, use group_by
with both date and comment included (to get frequency for combination of date and keyword together). The use of summarise
with n()
will give number of mentions.
Here's a complete example:

I have a data in JSON format, I am currently working on creating data filtering. I created a sorting of numbers from smallest to largest and reverse, and sorting of names, which work when clicking on input [checkbox]. They work well, but individually and confuse each other's result (i.e. if you click on price sorting, it knocks down sorting by product name and reverse). I want to connect them in .filter() function, but I don't understand how to do it correctly.
Sort works, but on click on other checkbox knocks previous sort values:
