    Need to write 3 scripts in c++. The scripts must have two functions each, the first to encrypt the file, the second to decrypt the file. Well, each file should be approximated as follows: int main() { encrypt("", "","(key)"); decrypt("", "","(key)"); } File encryption must be implemented using the following libraries: Salsa20 HC-256 SOSEMANUK The source code there is written in C, but it can be plugged into c++ and compiled into one file. It also needs optimization of RAM, and the correct read/write file, so that the memory is freed after the encryption of the file. Write code and test it strictly on Linux, because RAM on windows and linux in c++ is optimized differently. Also for clarity, there is an example of...

    Brief I have a windows app that records a users video from a webcam and audio from an external mic The app has been written in C# Windows Form and uses AForge,NAudio, DirectShow libraries. ( Currently, it records video and audio in the separate file and has playback synchronizing issue 1-4 seconds difference) I need a solution so it records audio from a specific microphone with Video from a Webcam when played back the audio is in sync with the video with no frame loss. Also seems to be some issue with identifying the camera if using windows 11, a fix for this would also be appreciated. I will supply you with read access to the depository on bitbucket.

    The robotics cape was designed to turn the beagle bone black (BBB) into a full featured drone platform. The capes API comes with the all drivers and tools necessary to interface the on-board IMU, PWM channels, MAVLink and more. It also comes with example code in C for an easy start. QGC (Ggroundcontrol) is an open source software acting as the ground station for drones. It uses the MavLink protocol to communicate with drone platforms. That said, we need someone willing to work with us on a project where we use the BBB together with QGC to control underwater drones. A first task would be to send the IMU data from the robotics cape to the QGC using the MavLink protocol and display the physical orientation of the drone. Later we need to be able to close loop control up to 8 thrusters via...

    I have assets for a full game, but it was coded back in 2001-2004, and is using old C language, written poorly, and uses technologies (like online multiplayer) that are dated. I have the source code to the server and the editors (map editor, quest editor, etc.) but I do not have the source code to the game client. My goal would be to convert the current source code to be compiled in a more modern environment. I would also like to make a new front end client. When the project is finished my hope is that I would have a game in the same state as it is in now (but with modernized code) and the ability to edit and add more to the game in the future using the editors.
