It seems to be that we've got a lot of people in this subforum at the minute looking for help with school/college programming projects at the minute.

   I keep wondering if c++ and c programming languages can be separated. in the last two decades, c++ programming language has evolved too much and currently it has lee and less relationship with the c language. Does this mean that in the nearby future these two languages will be separated?

11. PIC16LF1618 - mpasm how to work with arrays

    Hi, I'm looking for a means to write a subroutine that fills an array with a value, as well as a way to parse/read data from an array. I've been looking about various keywords from the standpoint of a C/C++ coder, but I'm not sure how the piece fits together: - declare array in cblocks, which I am familiar with - What is mpasm's approach to array[index] access? - How do I raise the index? - How can I get from one array place to the next? - How do I create a while loop? In assembly, is the recursive loop GOTO $-n the only way?

12. What this compilation error means? I cannot solve it

    I am making a fairly simple tictactoe game with Borland C++ Builder. But it is the first time i am making a project alone with it. I have worked with it for a few months, before, but in projects that were working. I just adjusted or added some kinds of things. My project is a win32bit thing. First, i had an issue with the "onClick" event function. The 9 buttons (the game positions where we play) must have 9 different position. When i drawed the dialog, i copied an empty and basic button to have them 9. But after doing this, if i double clicked the "onClick" event of one of them, and created a new function, this function were "magically" given to all 9 buttons.…

13. Py2EXE Not Importing PIL Properly?

    I wrote myself a little QR code generator. I installed a flatpak of one and it would just straight up crash if you entered too much information, so I decided to just tinker around and write my own in Python that has some proper error handling to warn me if I give it too much to work with instead of just crashing out of the blue. I fired up my Windows 10 VM, did: python -m pip install qrcode And a handful of other libraries so that the raw Python file itself runs properly on Windows. But, when I try to compile it with Py2EXE, the resulting EXE file complains about not being able to import "Image", even though I've double checked that it is indeed…

19. Jellyfin and Fail2Ban

    Could somebody tell me what I'm doing wrong? I'm trying to set up Fail2Ban to handle my Jellyfin service. Jellyfin has a built in "block this user after X failed login attempts", but I'd like to use Fail2Ban in addition to that to block attempts to log in with incorrect usernames and such that wouldn't get caught by the built in autoban feature of Jellyfin. Fail2Ban sees the jail and when I query the jail status, it appears to correctly report a list of the appropriate log files, but when I intentionally enter incorrect credentials Fail2Ban doesn't register the failure, and I'm fairly certain it's something to do with my regex in the filter file. First off,…

21. Efficient/fast CSV file from client (Windows) to server (CentOS)

    Hello, I am seeking some guidance on the best possible way to send a CSV file from a Windows client to CentOS server with the lowest overheads. The CSV file changes perhaps 2-3 times a second and I need to send this to the server for data capture and processing. This send process happens for perhaps 8 hours and then sleeps for weeks or sometimes months. When not sleeping I need to send the CSV as fast as possible, once per second would be acceptable. Appreciate any suggestions or guidance. Client side current: Run a program and sends data when datafile.csv file is modified. Uploads via WinSCP / SFTP. Overhead of SFTP mean transfer takes 1-3 seconds before send…

23. Batch Script - Take user input and rename+move files

    I am having difficulty with a script for work; what I am looking to do is allow the user to input a string, then the replacement string and the script will rename the files in the directory and move them to a location.
