Let’s recreate the Simon game of the 1980s using a Raspberry Pi and Sonic Pi!

Let’s learn how to flash an LED on the Raspberry Pi when someone sends us a new email.

Let’s combine the SqlDataReader’s GetFieldValue and GetOrdinal methods into an extension method that lets us pass a column name and get back a specific type.

In WPF, a ListView allows for quite a bit of flexibility. Let’s take a look at filtering a ListView, using input being typed into a TextBox.
