    a: T,
    b: T,
}

impl<T> PairSet<T> where T: Eq {
    /// If the values are different, creates a `PairSet` with them.
    pub fn new(x: T, y: T) -> Option<PairSet<T>> {

I noticed this in my syslog:

Mar 19 08:23:23 ralph systemd[1]: Configuration file /lib/systemd/system/nvidia-persistenced.service is marked executable. Please remove executable permission bits. Proceeding anyway.

I corrected the permissions with:

sudo chmod -x /lib/systemd/system/nvidia-persistenced.service

I'm running Ubuntu 17.10.

After I installed Terminator, it became the default terminal in Gnome.

I would like to switch back to the default terminal.

First, I checked:

gsettings get org.gnome.desktop.default-applications.terminal exec

Pros and Cons of Wrapper Types in Rust

I've written a mathematically-oriented and computatioally-intensive application in Rust. While the mathematical theory is not necessarily difficult, keeping the various quantities clear required some care.

For this reason, I'm refactoring it to clear it up. I've created some custom structs to wrap various mathematical types.

For example, I created a type to write PDFs (probability density functions)
