Build an application using HTML, CSS, javascript, json. It is not necessary for backend to be working but the frontend should be good. App should to simple and useful in our day to day life. For eg- grocery shopping list or alarm or weather forecast or reminder.

Design a class named Octagon that extends GeometricObject class and implements the Comparable and Cloneable interface. Assume that all eight sides of the octagon are of equal size. The area can be computed using following formula:

Write a test program that creates an Octagon object with side values 5 and display its area and perimeter. Create a new object using clone method and compare the two objects using compareTo method.

Describe the data breach incident and the primary causes of the data breach.

Windows PowerShell

Log in as Tawny Madison and create a directory called c:\users\tmadison\research and within it, another directory called departmental meeting minutes. Set the permissions on the departmental meeting minutes directory so that the user tmadison can read and modify it, any other members of the research group can only read it, and no one else can do anything with it. (If someone is listed as belonging to both the research group and another group, they should still be allowed to read it.)

This is what I have so far:

1) New-Item -Path “c:\users\tmadison\research\departmental meeting minutes” -ItemType “directory”

2) Icacls “c:\users\tmadison\research\departmental meeting minutes” /grant “user”:r

I used New-Item to create the directory but I'm having trouble setting up permissions for the directory "departmental meeting minutes".

These are the permissions I need to set up using PowerShell.

"tmadison" Owner = Read & Modify

"research" Group = Read Only

Everyone else = Cannot do anything with it

I need to separate my program into header files/need to use header files for this program.Their needs to be 2-3 files one of which is the menu. thanks!

The Delta Insurance Company is having a policyholder subsystem which has started giving trouble. Over the years, the application evolved from using fixed length, multi-record type files to using a hierarchic database to using a relational database. The programs did not change much, but the data structures changed radically. Program code was patched to provide for the new data structure. The amount of people-time allocated to policyholder maintenance grew 15% per year over the last five years and is now costing as much per year as it did in 1980 to develop the original application. No one ever considered reevaluating the subsystem for redevelopment, but they would like to now. Upon inspection, the documentation was found to be up-to-date and includes flow charts and data flow diagrams. There are no current diagrams of the data structure. There are also no historical files of decisions or of changes. Apply the concepts of change management to discuss how should the company get this application in order? What type( s) of maintenance should they consider for the next set of changes?

Write Matlab code that solves (dy/dt)= yt^3 - 1.5y on the interval t= 0 to 2 where y(0) = 1. As well as (dy/dx) = (1+4x)y^.5 on the interval x = 0 to 1 where y(0) = 1 using Matlab functions that solve any ODE using the below methods

• Midpoint Method
• Huens Method

Functions need to call:

• Error desired
• number of iterations
• Step size
• Initial Interval
• y(0)

And return

• Result
• Error of that result

Please perform the following tasks using a Timer Control:

1. When an NO Push Button (I:0/0) is pressed (I0) and released, a Pilot Light (O:0/0) will be on and after 7 seconds (T4:0), a single-active cylinder will be pushed forward.
2. The piston will remain at its position for another 5 seconds (T4:1) and then it will automatically retract. The pilot light will be off and the timer will also be automatically reset. The whole cycle can then be repeated.

(a) Write a stack class that is based on a linked list. It can be just pop(), push(), and anything you need for those methods or testing.

(b) Write a queue class that is based on a linked list. As above, it can be just enqueue() and dequeue(), as well as anything you need for those methods or testing.

(c) Write some test cases, trying to include edge cases. Why did you choose those tests? Did you get the results you expected?

RCS (Revision Control System), a configuration management tool, adopts a reverse delta approach for storing multiple versions of a file. To optimize storage, RCS only stores the latest version of each configuration item and the differences between each version. For example, assume a file has three revisions—1.1, 1.2, and 1.3. RCS stores the file as of version 1.3, then the differences between 1.2 and 1.3, and finally the differences between 1.1 and 1.2. When a new version is created, say 1.4, the difference between 1.3 and 1.4 is computed and stored, and the 1.3 version is deleted and replaced by 1.4. Do you think RCS is able to apply Version Control in this case? Research the internet and find the pros and cons of this tool as a configuration management tool. Also, suggest some other tool that could be used for this scenario.
