Suppose two threads with a shared variable "lockywocky" execute the following instructions: shared int lockywocky; Thread 1: lockywocky = 0 lockywocky lockywocky + 1 lockywocky lockywocky - 1 cout << lockywocky + 1 << endl; = Thread 2: lockywocky = 0 lockywocky lockywocky - 1 lockywocky lockywocky + 1 cout << lockywocky + 1 << endl; = = It may seem like this code can only bring the number "1". Demonstrate that a race condition can cause it to instead print "2" by number each instruction to form a sequence that triggers the bug. You do not need to continue numbering instructions once your code has reached the cout that prints '2'.

The Cupid matchmaking Service maintains two files - one for the male clients and another for female clients. Each file contains a client ID, last name, first name, and address. Each file is in client ID order. Use the provided pseudocode to write a C++ application that merges the two files into one file containing a list of all clients, maintaining ID member order. // Pseudocode Project8// Start// Declarations// InputFile inFile1;// InputFile inFile2;// OutputFile outFile1;// num mClientNumber, fClientNumber// string mClientName, fClientName// bool atLeastOneFileNotAtEnd = true// bool inFile1Written = false// bool inFile2Written = false// output "File merge processing starting"// open inFile1 "MaleClients.rtf"// open inFile2 "FemaleClients.rtf"// open outFile1 "MergedClients.rtf"// read mClientNumber and mClientName from inFile1// read fClientNumber and fClientName from inFile2// while ( atLeastOneFileNotAtEnd == true )// if (inFile1 is EOF)// if (inFile2Written == false)// output…
Part C Consider the standard web log file in assets/logdata.txt. This file records the access a user makes when visiting a web page (like this one!). Each line the log has the following items: • a host (e.g., '146.204.224.152') a user_name (e.g., 'feest6811' note: sometimes the user name is missing! In this case, use '-' as the value for the username.) • the time a request was made (e.g., '21/Jun/2019:15:45:24 -0700') • the post request type (e.g., 'POST /incentivize HTTP/1.1' note: not everything is a POST!) Your task is to convert this into a list of dictionaries, where each dictionary looks like the following: example_dict = {"host":"146.204.224.152", "user_name":"feest6811", "time":"21/Jun/2019:15:45:24 -0700", "request":"POST /incentivize HTTP/1.1"} In [ ]: import re def logs(): with open ("assets/logdata.txt", "r") as file: logdata = file.read() # YOUR CODE HERE raise NotImplementedError(() In [ ]: assert len(logs()) == 979 one_item={'host': '146.204.224.152', 'user_name':…
Some already helped me with this but I get the following error: Exception in thread "main" java.util.NoSuchElementException: No line found at java.util.Scanner.nextLine(Scanner.java:1540) at BirthdayReminder.main(BirthdayReminder.java:57) Write an application that allows a user to enter the names and birthdates of up to 10 friends. Continue to prompt the user for names and birthdates until the user enters the sentinel value ZZZ for a name or has entered 10 names, whichever comes first. When the user is finished entering names, produce a count of how many names were entered, and then display the names. In a loop, continuously ask the user to type one of the names and display the corresponding birthdate or "Sorry, no entry for name" if the name has not been previously entered. The loop continues until the user enters ZZZ for a name. The code for above program is given below: Step 2 Java: import java.util.*; public class BirthdayReminder{ public static void main(String[] args) {…

Lab Activities: Exercise 1: 1) Write a thread class TabPrinter that prints the elements of an array of integers (in one line) every 2 seconds 5 times. Use the way of extending the class thread. Write the main method which creates and starts three threads Printer which will print different arrays of integers. After that it prints "Main won't wait. Main exits". 2) Modify the above thread program so that you implement the interface Runnable. Make the main thread waiting till all other threads finish execution.
Need help to implement networking in python Server.py Load data from file This option will ask the user for a fully qualified path and will load a JSON file containing the information for users and pending messages. The format of the JSON file will be defined based on your implementation and it will the same used to save the data into file (menu option #4). Functionalities the server must provide: 1) User Sign Up: adds a user identified by a phone number to the system. a) Protocol: USR|username|password|display_name b) Response: 0|OK for success. 1| for an error. c) The server should validate that the username does not exist 2) User Sign In: verify user credentials a) Protocol: LOG|username|password b) Response: i) 0|OK → the credentials are correct. ii) 1|Invalid Credentials iii) 2|Already Logged In → in case that the user is logged in from another client. c) This will help the server knowing which user is connected. d) The server should keep a list of connected clients, which should…
please write with proper explanation. Question half solution is here please write what is main disadvantages of this approach? Half solve questions: Mutual Exclusion: Mutex is an abbreviation for Mutual Exclusion. It is a programme object that prevents multiple users from accessing a shared resource at the same time. When a process accesses a shared variable, it is said to be in the critical section. When no two processes are present in the critical section at the same time, this is referred to as Mutual Exclusion or Mutex. while (true) { semaphore sem = S; while (S <= 0) do no operation { S = S-1; wait (S); } /*critical section*/ while (S > 0) { S = S+1; signal (S); } /*remainder section*/ }
