In the fall 0f 2008 Countrywide Morgage Corporation announced that the private information for thousands of their customers, including social security numbers and loan numbers, had been compromised. Countrywide offered these customers a free 2-year subscription to a credit protection service. Should this action shield Countrywide from customer lawsuits? Could Countrywide do more? Should they? Given that it was a Countrywide employee who sold the data, does this change Countrywide's responsibilities toward the affected customers? Explain why or why not.

Your task is to build an Android application that satisfies the following requirements:
Has two activities: MainActivity that implements the main functionality of the application and AboutActivity that shows your full name as per college record and student id
The AboutActivity should be available through a menu
A back button should appear in the ActionBar of the AboutActivity that takes user back
to the MainActivity. It should be done through configuration!
MainActivity should implement the following functionality
o read the following input from the user: § number of hours worked
§ hourly rate
o calculate the pay using the following formula
§ if no of hours is less or equal than 40 then pay=no_of_hours*hourly_rate
§ else, pay=(no_of_hours-40)*hourly_rate*1.5 + 40*hourly_rate o calculate the tax using the following formula
§ tax=pay*0.18
o present following data to the user
§ pay
§ overtime pay § total pay
§ tax

An ink droplet with a mass of 1.2E-10 kg and a charge of
-1.6E-13 C is moving horizontally at 17 m/s. It then passes between
2 deflection plates. The horizontal length L of these plates is 1.5
cm. There is a uniform electric field of magnitude 1.4E6 N/C,
directed downward, between the plates. Everywhere else, the
electric field is zero.
a. Calculate the magnitude and direction of the droplet’s
acceleration between the plates. Ignore gravity.
b. Calculate the vertical deflection of the droplet when it reaches
the end of the plates.

Time Complexity: Build a table in Excel and record the time complexity taken by linear and binary search to look for an element with the following array sizes: 10, 50, 100, 200, 500, 700, 1000. Compare the performance of both algorithms highlighting the time complexity for both algorithms when run on small input size and when run on large input size.
To accomplish this, load a list with the file data and then create a program that selects at random X amount of elements from the original list (where X is a value that the user selects) and place them in an array, then select at random an element in the original list to search in the sampled array using both algorithms. Measure the time it takes for both algorithms on an array of a given input size.

Hello!
I need to present my xml file on the Windows form application I tried but it dosent work at button 2, I cann't show Xml_file. What is problem here please? have you any suggest or solution .

const string XML2 = "Path";
const string ResultFile = "Path";
public Form1()
{
InitializeComponent();
}
private void Run(object sender, EventArgs e)//run button
{
Compare_D_R d_R = new Compare_D_R();
d_R.compareD_R();
}
private void Button3_Click(object sender, EventArgs e)
{
xmlGridView.ClearSelection();
}
private void Button2_Click(object sender, EventArgs e)//show
{
if (showinput.Text != null) {
string DefaultFile = "DefaultFile":
string Alternative = "AlternativeFile";
string Result = "ResultFile";
if ( DefaultFile==showinput.Text) {
DataSet ds = new DataSet();
xmlGridView.DataSource = ds.ReadXml(XML1);
}
if (Alternative == showinput.Text) {
xmlGridView.DataSource = XML2;
}
if (Result == showinput.Text)
{
xmlGridView.DataSource = ResultFile;
}
else
{
MessageBox.Show("Invalid Input");
showinput.Text = string.Empty;
showinput.Focus();
}
}
}
private void TextBox1_TextChanged(object sender, EventArgs e)
{
}
private void XmlGridView_CellContentClick(object sender,DataGridViewCellEventArgs e)
{
}
private void Button4_Click(object sender, EventArgs e)
{
}
}
}
How can I play/show my xml_file on the grid view. I'm really new in winform so please try to understand my question. if you have a better Idea you are welcome it is a free desigen.
