Which of the following statements is not true regarding Debugging?  1- Valuable information can be retrieved from API functions. For example, the presence of WS2_32 means that the program might use Windows 32-bit functions. 2- x86dbg is not able to recognize the WinMain function where the real code starts. 3- CFF Explorer can show imported registry items and cryptography APIs.
The issue: Do you "sort of" know what method you're looking for's name? Because the procedures in the Windows API have incredibly inconsistent names, this is a common issue for programmers who work with Microsoft Windows. Not much better are UNIX programmers. The only issue is that UNIX prefers to omit letters from system call names (for instance, creat), which results in naming conversions that are inconsistent.

Build a Java game based on Rock Paper Scissors Lizard Spock, an extensionof the classic game Rock Paper Scissors. The application is to be based on a client and server architecture where a minimum of 3 clients should be able to connect to the server. The rules of the game are as followsScissors cuts paper.Paper covers rock.Rock crushes lizard.Lizard poisons Spock.Spock smashes scissors.Scissors decapitates lizard.Lizard eats paper.Paper disproves Spock.Spock vaporizes rock.Rock crushes scissors.Minimum Requirements:- Make a desktop application using the Java programming language (SE)- Either Java RMI or socket programming should be utilized- Multiple clients should be able to use the application simultaneously- GUI and Audio is expected for a pleasant UX create using ANDRIODSTUDIO PLEASE
Answer the following questions What is Socket Programming in Java? Differentiate between any three stream sockets and datagram sockets Explain the life cycle of ServerSocket class (Server side) in Java. Your explanation should include detailed steps. Explain the life cycle of Socket class (Client) in Java. Your explanation should include detailed steps. Write a simple Java program for establishing a client and server using socket
Write a Java application for a server that listens to a client. The server should run on port 8250. Once the server is running it should output “Server is starting….”, then it should wait to receive a message from the client. Once it receives the message, it should close the socket. Create a client that sends a message to the server through port 8250. The message that should be sent to the server should be the sum of two numbers. Once it sends the message, it should close the socket. Figure 2 shows messages from the server:

Task 3: Measure the Entropy of Kernel In the virtual world, it is difficult to create randomness, i.e., software alone is hard to create random numbers. Most systems resort to the physical world to gain the randomness. Linux gains the randomness from the following physical resources: void add_keyboard_randomness(unsigned char scancode); void add_mouse_randomness(__u32 mouse_data); void add_interrupt_randomness(int irq); void add_blkdev_randomness(int major); The first two are quite straightforward to understand: the first one uses the timing between key presses; the second one uses mouse movement and interrupt timing; the third one gathers random numbers using the interrupt timing. Of course, not all interrupts are good sources of randomness. For example, the timer interrupt is not a good choice, because it is predictable. However, disk interrupts are a better measure. The last one measures the finishing time of block device requests. The randomness is measured using entropy, which is…
