kandi X-RAY | knock Summary

knock is a C library typically used in Utilities, Development Tools applications. knock has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

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.

            Out of Range error Copying UsedRange - Why did this break?
            Asked 2021-Jun-09 at 08:46

            (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:

            1. File dialog and open Excel file.
            2. Open the workbook
            3. Copy data in first sheet to clipboard
            4. Paste into A1 on pre-existing sheet in ThisWorkbook
            5. 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 :)

            APCSP create task issue - Method ends program after being called
            Asked 2021-May-21 at 16:19

            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!

            PostgreSQL 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.

            Using flexbox, menubar pushes rest of body off center
            Asked 2021-May-14 at 20:54

            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.

            Answered 2021-May-14 at 20:54

            This 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.

            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.

            Unless 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.

            As 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.
