The Washington Post has a simulation and visualization of how fast Ebola spreads and how deadly it is compared to other infectious diseases. I ran the simulation:
A comparison that has been made is to the Flu, which kills over 30,000 people every year in the US. While this figure is certainly true, Ebola is much more deadly, with a death rate of 70% this year. This is visualized very well with this simple comparison:
Flu spreads fairly rapidly, infecting 100 people within 14 days. However, only 2 of those people will die of Flu.
Ebola, by comparison, spreads more slowly, taking 68 days to infect 100 people. But the consequences are much more severe – about 70% of those infected will likely die.

Jen Cardello has a excellent post up with ten usability issues found on the HealthCare.gov (Obamacare) web site. Many of these issues are worth reading about for any web site or dashboard that you develop or maintain.

I’ve been using Stack Overflow for a couple of years now. In my opinion, this is the single best site to search for answers to technical or programming questions. Highly recommended! I post there as user kevin-p
If you haven’t heard of Stack Overflow, its Wikipedia article provides a good overview of how it works.
My C#.NET application needs to read from an Oracle database. There are many elaborate ways to connect to a database in .NET, including the Linq for Entities ORM. However, this was way too much for my purpose. I’ve found the following code to be much simpler. It’s largely copied from a C# Station post. The key difference is that you have to use the OracleClient class.
First: Make sure that your project has a reference to System.Data.OracleClient
string connectionString = @"
OracleConnection conn = new
OracleDataReader rdr = null;
// 2. Open the connection
// 3. Pass the connection to a command object
OracleCommand cmd = new OracleCommand(
"select * from mytable", conn);
// 4. Use the connection
// get query results
rdr = cmd.ExecuteReader();
// print each record
for ( int i = 0;
// Print each field
// close the reader
if (rdr != null)
// 5. Close the connection
if (conn != null)
} // End of try-catch-finally
