text-shadow: 0 0 0 #000;

Using vagrant to run virtual machines with desktop environment
...l machines, running on VirtualBox. We would like to move one step further, and use the capabilities of Vagrant to have the description of the machine in a text file and then be able to "raise" that machine based on that text file.

How do I print the type of a variable in Rust?
...
If you merely wish to find out the type of a variable and are willing to do it at compile time, you can cause an error and get the compiler to pick it up.

let mut my_number: () = 32.90;

Use of Application.DoEvents()
