For this assignment, name your R file fastfoodStats.R For all questions you should load tidyverse, openintro, and lm.beta. You should not need to use any other libraries. If the tidyverse package is not installed, you’ll need to do a one-time installation from the Console Window in RStudio like this:install.packages("tidyverse")You cannot attempt to install packages in code that you submit to CodeGrade. If the openintro package is not installed, you’ll need to do a one-time installation from the Console Window in RStudio like this:install.packages("openintro")You cannot attempt to install packages in code that you submit to CodeGrade.

We will use the file classlist.txt. Note that it contains a list of usernames. 3. Write a script called finduser that is to be called as follows, where classlist is the name of the classlist file, and username is a particular student's username, either first name or last time. ./finduser classlist username The script should check that the correct number of arguments was received and print an error message if not, check whether the classlist file exists and print an error message if not, print the line of the given username in the classlist file If you have not been doing so all along, you should now add some comments to your script and thoroughly test it! 4. Write the script into your lab report.
Using JAVA, Create a File Menu in your GUI Add a file menu to your BulbGUI with options to open any file for reading (and displaying the file as in Project 2), and one to Quit the program. You will need a FileMenuHandler class to handle the events from the FileMenu. Be sure to use getAbsolutePath() when getting the file from the JFileChooser, not getName(). Handle Exceptions Create an exception called IllegalBulbException (by extending IlegalArgumentException as shown in the lecture) and have the constructor of the Bulb throw it. For our purposes, a Bulb is illegal if the wattage is less than 5. Use a try/catch statement to catch this exception in your program, and display the erroneous Bulbs to the console (do not put them in the ArrayList). Use ArrayLists Use an ArrayList to store the unsorted Bulbs. For this project, display only the unsorted bulbs in the GUI.

For Submission, create the kernel module, install it, and remove it and then show a screenshot of your log file that has the hello world and goodbye world lines in the log. A few notes. You may need to do some things as root (the admin user). In order to become root (not groot - even though i know we are all watching infinity wars at the start of class) you can type su - root into the console and enter your password. I would make sure you have a snapshot done before you do this. Become root and do the following 2 commands in your terminal in the VM apt update apt upgrade -y These commands will update your system and may be needed to ensure you have completely up to date packages and software A note on making the hello-1.c Add the following line of code at the end, it will fix the issues we were having last night. Forgot i had to add that in. Its basically just tagging your kernel mod to have the gnu public license, which we had talked about in chapter 1. MODULE_LICENSE("GPL"); Please…
Our users do not want to have to re-enter the price levels each time the app starts. Therefore, we need to save the price levels to a file on disk – called levelsFile - and populate the levelsList with the file’s items when the app starts. Also, every time the user manipulates the values in levelsList, levelsFile needs to be updated accordingly. The easiest way is not to update the file, but to simply override it (create a new file) with the new values in levelsList (each time the user manipulates items in the list). Two new methods need to be created in the PriceChecker class. They are readLevelsFromFile() and writeLevelsToFile(). And then the Main Code Section must also be updated to use these methods in the object. Note: The changes required to the Main Code Section are supplied on the next slide, but you need to complete the skeleton code of the two newly mentioned methods (supplied on subsequent slides).

Find the words in the word list “dict.txt” that contain the string “gry”. Write a two-line shell script called “lookfor1.sh” that executes this command to look for words containing “gry” in dict.txt. The first line should specify that the program “/bin/sh” is to be used. The second line should contain your command.

This is sample data from my JSON file: "firstName" : "Juan","middleName" : "Dela""lastName" : "Cruz","username" : "JuanDelaCruz","password" : "1234", I already have a JAVA GUI that displays the data of each user in a table format. I need the part of my program that will allow the server to either accept or reject the user. If the user is accepted, the credentials of the user will be saved in another JSON file. If rejected, the server will do nothing.
Download words_alpha.txt from https://github.com/dwyl/english-wordsLinks to an external site. Implement the "wc" command to get statistics By adding a "-f" that outputs letter counts as well. Word Count: the "wc" commandTest it out. You are reimplementing that command! PLUS ONE NEW OPTION You need to look at it's --help to understand! Make it identical except for options that are not listed below. Note that command operates on multiple files. Especially how specifying an option "turns off" the other default ones. Main options to implement-c / --bytes-l / --lines-L / --max-line-length-w / --words(do the minor ones too)New option to implement-f - output frequency counts of printable characters at end (format " " on a line)Options NOT to implement-m / --chars--files0Write 1-3 unit tests,
2. Read all eight messages into Mailbox object from the file of "messages1.txt". The values for each line will be used to initialize each instance variable of the Message object, and then added into the Mailbox object. Important: Your must read the values in from the file using Scanner object, you are not allowed to initialize the objects manually. 3. Print out all messages using printAllMessages () method. Your output should look like Figure 2.
